Privacy Policy

Last updated: July 29, 2026

1. Who We Are

Mixtuby (mixtuby.com) is a free web application that lets you create and play YouTube music playlists. The service is operated from Romania.

2. Information We Collect

Account data (if you register): email address, name (optional), and profile picture (if using Google Sign-In).

Usage data: playlists you create, app settings, and preferences.

Lyric search queries: when you use "Find a Song by Lyrics", the text you enter is processed to find a matching song — including, if needed, by the third-party services listed in section 6 — and cached on our servers for up to 24 hours to speed up repeat searches. We do not link these queries to your account.

Cross-device playback state (if you are logged in): to let you resume listening on another device, we store the currently playing YouTube video, its playback position (in seconds), your playback queue (up to 50 track references), an optional playlist name/icon, and a device label we derive from your browser's user-agent (for example "iPhone", "Mac", or "Windows" — we do not store the raw user-agent). We also store a random device identifier that your browser generates and keeps in its local storage — it contains no personal data and is not derived from your hardware; it exists only so each of your devices keeps its own place in the song instead of overwriting the others. We keep the most recent playback state per device (overwritten each time you play on that device), so that opening Mixtuby on your laptop can offer you the spot you left on your phone.

Screen-lock PIN (only if you set one): the optional 4-digit Screen Lock (Child Lock) is available to signed-in users. We store your PIN on our servers only as a one-way bcrypt hash (we cannot read the digits); it follows your account so you can unlock on any device. You can always change your PIN from Player Settings; tapping "Forgot?" on the lock screen signs you out so you can set a new PIN after signing back in.

Analytics data (with your consent): Google Analytics 4 collects anonymized usage statistics such as pages visited, session duration, browser type, approximate location (country/city level), and device type. This data is processed by Google under their Privacy Policy.

Push notification data (only if you turn on a reminder): to send your device reminders when the app is closed, we store a push subscription that consists of the push service endpoint URL provided by your browser, two encryption keys (so only your device can read the message), a device label we derive from your browser's user-agent (for example "iPhone · Safari"), and your device's time zone (for example "Europe/Bucharest"). We obtain the time zone from your browser's locale settings only — we do not use GPS, location permissions, or your IP for this. For each reminder you switch on, we also store which reminder it is (for example "Daily Mix"), the time you chose, how often it should repeat (daily, every 3 days, weekly, or specific days you pick), and the date it was last sent — so it arrives at the right moment in your local time. For the Meditation reminder we also store which meditation session you chose it to open (for example "Body Scan" or "Sleep Wind-Down"), so the notification takes you straight there; it is a content preference, not a health assessment, and it is deleted when you turn that reminder off. This subscription is anonymous by default and is linked to your account only if you are logged in. Most reminders carry only a short generic message such as "your daily mix is ready"; the one exception is a to-do reminder you set yourself (below), whose notification shows the task's own text. Turning a reminder off unsubscribes that device immediately. The Pomodoro timer's optional end-of-phase alert is a different thing: your own browser shows it locally while Mixtuby is open, so it needs your notification permission but creates no push subscription and sends nothing to our servers.

Notes you write (ideas & to-dos): the sticky-note ideas and to-do items you create in the Notes panel. They stay in your browser's local storage unless you are logged in, in which case they sync across your devices, stored encrypted at rest. We never read or share them (limits: 100 ideas, 200 tasks).

To-do reminders (only if you set one): when you tap ⏰ on a task and pick a time, we store the task's text (up to 200 characters, encrypted at rest) and the reminder time, linked to your device's push subscription. This works without an account and is not tied to your account. The record is deleted as soon as the reminder is sent, or when you check off, delete, or clear the task; unsent reminders older than 24 hours are auto-deleted.

Focus timer stats (Pomodoro): the Pomodoro focus timer keeps a tally of your focus rounds — your current day streak, the date you last focused, rounds today, and your all-time rounds and minutes — plus a rolling count of rounds per day for the last 30 days, which draws the seven-day chart. Signed out, this stays in your browser's local storage. Signed in, it is saved with your account settings so your streak and your week survive a new device. It records only counts and dates — never what you were working on.

3. Legal Basis for Processing (GDPR)

We process your data under the following legal bases:

  • Contract performance — to provide your account, sync playlists, resume playback across your devices, and carry your focus-timer streak between them
  • Consent — for analytics cookies (Google Analytics 4), which you accept or decline via the cookie banner, and for notification reminders, which are off by default and which you can withdraw anytime by turning each reminder off.
  • Legitimate interest — for essential session cookies and security (rate limiting)

4. Cookies & Local Storage

Essential cookies (always active):

  • _mixmusic_session — Rails session cookie for authentication
  • remember_user_token — keeps you signed in across visits (sliding, up to ~1 year)

Analytics cookies (require consent):

  • _ga, _ga_* — Google Analytics 4 (loaded only after you click "Accept")

Third-party cookies:

  • YouTube embedded player may set cookies when you play a video. These are governed by Google's Privacy Policy.
  • YouTube may set advertising cookies (e.g., for ad personalization, frequency capping, view counting). Mixtuby does not control these — they are managed by Google.

Local storage (not cookies, no consent needed):

  • mixtuby-theme — your dark/light theme preference
  • mixtuby-settings — player settings (crossfade, speed, etc.), your Pomodoro preferences (rhythm, custom durations, sound, auto-start, alerts), your Pomodoro focus tally (streak, totals, and rounds per day for the last 30 days), and your Meditation preferences and tally (guidance mode, background visuals, last session and length, day streak and minutes meditated) — the Meditation tally never leaves this device
  • mixtuby-cookie-consent — your cookie consent choice
  • pwa_installed — PWA installation state
  • mixtuby-layout-* — your grid/carousel layout preference for playlists
  • mixtuby-locked — whether the screen lock is currently engaged
  • mixtuby-constellation-* — your Constellation game progress (mode, XP/rank, and which constellations you've discovered), stored only on this device
  • mixtuby-notes — your ideas & to-do items, cached on this device (synced to your account if signed in)
  • mixtuby-notes-prefs — your Notes text settings (size, ink color, bold), stored only on this device
  • mixtuby-device-id — a random identifier for this browser, so cross-device resume can tell your devices apart (no personal data, not shared with anyone)
  • mixtuby-session — the playlist, track and position you last played on this device, so the Continue card can offer it back

Plus small preference keys for individual tools (games, sleep tools, prompts you have dismissed) — all stored only on this device and never sent anywhere.

5. How We Use Your Information

  • Provide and maintain your account
  • Sync your playlists across devices
  • Send password reset emails when requested
  • Understand how the service is used (analytics, only with consent)
  • Protect the service from abuse (rate limiting)

6. Third-Party Services

  • YouTube Embedded Player — streams content directly from YouTube. We do not download or store any audio/video.
  • Google OAuth 2.0 — optional sign-in method. We receive your email and profile picture.
  • Google Analytics 4 — anonymized usage analytics (only with your consent).
  • Genius (lyric search) — when you use "Find a Song by Lyrics" and the song isn't already in our catalog, the text you type is sent to the Genius API to identify the song. Only your search text is sent; we receive back the song title, artist, and thumbnail. We do not request or store full lyrics. Governed by Genius's Privacy Policy.
  • Mixtuby AI lyric assistant (powered by OpenAI) — if Genius and our catalog cannot identify your song, the words you type in "Find a Song by Lyrics" are sent to OpenAI (US-based) to suggest up to three songs you may mean. Only your typed text is sent — no account data, email, or identifiers. We do not use your input to train AI models, and we do not store it beyond the 24-hour query cache described above. Governed by OpenAI's Privacy Policy.
  • Browser push services (Apple, Google, Mozilla) — when you enable a reminder, it is delivered through the push service built into your browser/operating system (Apple Push Notification service, Google FCM, or Mozilla autopush, depending on your device). This is an inherent part of the Web Push standard; the message contains only the reminder text — which for a to-do reminder is the task text you wrote, and for all other reminders is a short generic message.

6.5. Workout Mode & Health Data (Premium)

If you subscribe to the optional Workout Mode, Mixtuby may collect and store the following health-related data that you choose to enter:

  • Fitness profile — sex, age, height, weight, training goals, equipment access, weekly schedule
  • Workout history — completed sets, reps, exercises, dates, AI coach interactions
  • Weight log — optional dated body-weight entries you record after workouts
  • Cycle tracking (optional, for users who enable it) — last period start date, cycle length, period length, daily logs (flow, mood, energy, symptoms, notes)

How we treat this data:

  • Stored encrypted in our PostgreSQL database (Render.com, EU-based)
  • Never sold, shared, or used for advertising — period
  • Not shared with employers, insurers, partners, or third parties
  • Used only to power your AI coach (Coach Vince) and your personal calendar
  • You can delete all of it anytime via Profile Settings → Delete Account

Cycle data is NOT medical-grade. Mixtuby is not a contraception, fertility planning, or medical diagnostic tool. See Terms of Service §7.5 for full disclaimer.

7. Data Sharing

We do not sell, trade, or share your personal information with third parties. We may disclose information only if required by law.

8. Data Retention

  • Account data — kept until you delete your account
  • Session cookies — the session cookie expires when you close your browser; the persistent login token lasts up to ~1 year and renews while you stay active
  • Cross-device playback state — the latest state is kept per device (overwritten on each play on that device); deleted with your account, or on request at privacy@mixtuby.com
  • Push subscription & reminder schedule — kept while a reminder is on; deleted when you turn off the reminder (the schedule goes with it), and otherwise with your account or on request at privacy@mixtuby.com
  • Notes (ideas & to-dos) — kept until you delete them or delete your account
  • Focus timer stats (Pomodoro) — kept in your account settings until you delete your account, or on request at privacy@mixtuby.com; the per-day counts roll off automatically after 30 days. The copy on your device is cleared when you clear your browser storage
  • To-do reminders — deleted when sent or when you cancel the task; unsent reminders are auto-deleted after 24 hours
  • Screen-lock PIN — the bcrypt PIN hash is kept until you change or remove it (Player Settings) or delete your account

App Guide

What is Mixtuby?

A free YouTube music player and mixer. Pick a mood or browse curated playlists, paste your own YouTube links, and enjoy continuous, gapless playback (with crossfade on desktop). On top of the music: karaoke with synced lyrics, A-B loop, and Vibe Mode — the original Mixtuby experience, with relaxing games and sleep tools. Not just music: anything that plays on YouTube works here — full movies, podcasts, DJ mixes. No account required.

Tap Mix. Play. Enjoy. to dive into Vibe Mode.

Quick Start

1

Add music

Search for songs directly, paste YouTube links, or scroll down and tap any curated album card. Preview tracks before adding — tap ▶ to listen, drag the seekbar to seek, then tap + to add to your playlist.

2

Play & customize each track

Press Play, then tap the settings icon on any track in your playlist to set its speed, A-B loop region, and volume. Tap Next to save and move to the next track.

3

Enjoy continuous playback

Tracks flow one into the next with no silence — gapless on phone and tablet, with a smooth crossfade on desktop. Your playlist, position, and settings auto-save right on this device — reopen Mixtuby and you land back on the exact playlist, track, and spot you were last listening to here.

Continue on another device

Start a song on your phone, finish it on your laptop. Sign in with the same account on both — cross-device resume is off for guests. Each device is remembered on its own, so the card always points you at the other one.

1

Play on one device

Listen as usual. While music is playing, Mixtuby quietly saves your current track, exact position, and whole queue every few seconds.

2

Open Mixtuby on the other device

A Continue card appears near the top of the home page: “Continue from 📱 iPhone — Pick up at 2:14”. Nothing changes until you tap it. The same card also offers a plain Continue where you left off when your last listen was on this device.

3

You decide — continue or dismiss

Two clear choices, never automatic — see below.

▶
Tap ▶ on the card to continue Tap the ▶ button on the card and your full queue jumps over and continues from the exact second you left off on the other device.
×
Tap × to keep this device Don't want it? Tap × and whatever is already on this device stays untouched — the card stays away for the rest of your visit.

Search & Preview

The fastest way to build a playlist — search, listen, and add without leaving the page.

▶
Preview a track Tap ▶ on any search result to hear it instantly. The full track plays in the main player with a seekbar on the result row.
DRAG
Seek within preview Drag the seekbar on the previewing track to jump to any point. A time bubble shows the exact position.
+
Add to playlist Tap + to add the track to your playlist. Preview stops automatically. Switch between results freely — only the last tapped plays.
TIP
Quick playlist workflow Search → ▶ preview → + add → search again → repeat. When done, tap Start Mix. Your previewed and added tracks are ready for continuous playback!

Find a Song by Lyrics

Forgot the title but remember a line — or just a few fuzzy words? Open the By Lyrics tab (the magnifier, next to Quick Start and Add Tracks) and let Mixtuby find it for you.

TYPE
Type or paste a line you remember Type a chorus line, paste a whole refrain, or just a few half-remembered words — the box grows to fit. Exact wording, spelling and order don't matter; a close fragment is enough.
🔍
Tap Search Nothing happens as you type — tap the search button when you're ready. Mixtuby checks its own catalog first, and only reaches out to find the song if it needs to.
💡
Not sure? Pick a “Did you mean?” suggestion If your words are too fuzzy to match exactly, Mixtuby AI suggests up to 3 songs it thinks you mean (artist — title, with the real line). Tap the right one and it loads into your player.
▶
Tap a result to play Found it? Tap the matching song and it loads straight into your player, ready to go.

Notes — I have an idea ✨

Jot down ideas and to-dos without ever stopping the music. Tap the little pencil button next to Your Mood in the hero — a panel slides in from the right on phones, or opens as a centered window on desktop. Two tabs inside: sticky-note Ideas and a Todo checklist.

💡
Ideas — pin sticky notes Tap ＋ New idea to pin a note to the corkboard. Tap any note to edit it right on the post-it — type your text, pick one of 8 colors, or tap 🗑 to delete. Drag the ⠿ grip in a note's corner to reorder the board. The first two notes are examples that vanish for good once you write a real one.
☑
Todo — a notebook checklist Write a task on a line — press Enter or tap away to add it. Tick the box to cross it out in red, tap ✕ to remove the line. The pencil button shows a cyan badge with how many tasks are still unchecked (up to 9+).
⏰
Reminders — a nudge for any task Tap ⏰ on a to-do, pick a date and time, and Mixtuby sends a push notification with the task's text when it's due. It works even without an account — just allow notifications when your phone asks. The reminder rings only on the device where you set it; checking off, deleting, or clearing the task cancels it.
⚙
Text settings — size, color, bold Tap ⚙ at the bottom of the panel to set your writing size (13–48px), pick one of 6 ink colors, or turn on Bold. These stay on this device only — they don't sync.
CLOSE
Four ways to close — music plays on Tap ✕, tap the dark backdrop, press Esc, or swipe the panel to the right. The music never stops, and the whole panel is hidden while you're in Sleep Mode.
☁
Saved on device — sign in to sync Your notes always save on this device. Sign in to your Mixtuby account and they sync automatically across all your devices — stored encrypted, never shared, and deleted for good if you delete your account. Limits: 100 ideas, 200 tasks, 2000 characters per note.
NOTE
Anyone with your unlocked phone can read them Notes aren't PIN-protected — on this device they're visible to anyone using your unlocked phone or computer. Keep anything truly private out of them.

Hidden Gestures

These are not obvious from the UI — learn them to get the most out of Mixtuby.

HOLD
Skip 5s buttons Tap to skip 5 seconds. Hold down to skip 5s every 0.3 seconds continuously until you release.
TAP / HOLD
A: and :B markers Tap the A: or :B label to set it to the current playback time. Long press to type a specific time manually.
TAP
✂ Share a segment When A-B loop is active, a ✂ duration label appears above the progress bar. Tap it to share that exact segment with a link.
HOLD
Theme toggle (moon icon) Tap to switch dark/light. Long press to activate system theme (follows your device settings automatically).
SWIPE
Pull to refresh (mobile) Pull down from the top of the page on mobile to reload.
DRAG

TAP
Grid ↔ carousel layout toggle Tap the layout button next to Quick Start and Saved Playlists to flip the album cards between a vertical grid and a horizontal swipeable carousel. Swipe (or click-drag on desktop) to scroll the carousel. Mixtuby remembers your choice for next time.

Per-Track Settings

Tap the gear icon on any track in your playlist to open its settings. Each track can have its own:

  • Speed — 0.25x to 2x (great for practice or podcasts)
  • A-B Loop — set start/end points, loop count, and what happens after loop ends
  • Volume — override the global volume for this track

Tap Next in the dialog to save and jump to the next track — perfect for setting up an entire playlist quickly.

Settings Panel

Open Settings (gear icon in navbar) to find these options:

Sleep Timer Set a timer (15m to 120m) and music fades out automatically. A countdown badge appears in the player. Tap again to cancel.
Notifications & Reminders Set gentle reminders to come back and play music, even when Mixtuby is closed. Off by default. See the Reminders section below for details.
Now Playing Shows the track name as an in-app toast (and a browser notification) when a new song starts, even with Mixtuby in the background. Stays on your device — off by default.
Crossfade (desktop) & Gapless On desktop, crossfade blends tracks together (1-30s). On iPhone and iPad, playback is gapless — each track goes straight into the next with no overlap. Turn crossfade off any time to force gapless everywhere.
Stars Theme, Video Quality, Audio Mode Enable animated stars background, choose video quality (360p–1080p), or switch to Audio-only mode to save data.

Reminders

Gentle nudges to come back and play music — they arrive even when Mixtuby is closed, in your own local time. Open Settings → Notifications to set them up. No account needed.

1

Turn on a reminder

In Settings → Notifications, flip on the Daily Mix card. The first time, your browser asks to allow notifications — tap Allow. On iPhone you must install Mixtuby to your Home Screen first.

2

Pick the time

Choose when the reminder fires — it arrives at the exact minute you set (17:44 means 17:44), always in your local time, no matter where you travel. Change the time later and you get a fresh reminder the same day.

3

Pick how often

Set the frequency: Daily, Every 3 days, Weekly (pick one weekday), or Custom (tap any days of the week you like).

Tap a reminder and Mixtuby opens right where you left off — same playlist, track, and spot. Turn a reminder off anytime — the device is unsubscribed and stops receiving it.

Sleep Mode tools

Sleep Mode is a calm full-screen mode with relaxing games and tools that play over your music — Karaoke, Rubber Duck, Baby Sleep, Typo, Breathe, Pomodoro, Party, Shooter, Constellation, Dropbeat, and Gems. They are all free, no account needed.

🌙
Browse every tool Open the Features page (/features) to see the full list of Sleep Mode tools, each with a short description.
TAP
Play now — jump straight in Tap Play now on any tool and Mixtuby enters Sleep Mode with that tool already open over your music — no setup.
🔗
Share a tool Tap ⏸ to open a tool's Paused · Settings, then Share this game / tool 🔗. It opens your device's share sheet (or copies the link on desktop) — whoever opens the link lands straight in that tool over their music.

Karaoke — Sing Along

Time-synced lyrics that scroll line by line over whatever is playing. Open Sleep Mode (moon icon) and tap Karaoke — the current line highlights automatically and follows the song. Switch tracks and the lyrics follow. Works on any YouTube song that has lyrics on file; if none exist, karaoke just stays off for that track.

Learn more about Karaoke →

Screen Lock (Child Lock)

Locks the screen so a child or a nightstand phone can't change the track, skip, or exit by accident — the music keeps playing. Screen Lock works with a free account. Tap the 🔒 lock button in the top navbar to lock; it then turns red.

Set or change the PIN in the Player Settings panel (Screen Lock card). Your PIN is saved to your account and follows you across devices. Forgot it? On the keypad, tap "Forgot?" — this signs you out (stops the music); set a new PIN after signing back in.

Rubber Duck (DJ Quack)

Digital debugging companion from The Pragmatic Programmer. Enable in Settings → Rubber Duck. Tap the duck button to summon DJ Quack — 12 skins, animated affirmations, particle effects. Explain your problem to the duck and find the solution yourself.

Learn more about Rubber Duck →

Sleep & Relax

Science-based sleep aid. Enable in Settings → Baby Sleep Game. In Sleep Mode, tap Sleep → choose a playlist (Baby, Rain, 528Hz...) → set timer → Start. Ducks fall slowly, tap to catch with warm particle effects. Screen dims progressively. Based on Cognitive Shuffle, bilateral tapping, and progressive dimming.

Learn more about Sleep & Relax →

Breathe

Guided breathing to fall asleep or calm down. In Sleep Mode, tap the Breathe card, pick a technique, then Start breathing. An animated circle expands as you inhale and shrinks as you exhale, with the phase and a countdown shown inside.

🎯
Pick by how you feel Each technique shows the benefit it's linked to: 4-7-8 to lower cortisol and ease into sleep, Box to reduce stress, Coherent to ease anxiety, Physiological Sigh to lower panic fast, Long Exhale to wind down gently, Wim Hof to boost energy, Alternate Nostril to sharpen focus. A relaxation aid, not medical care.
🌬️
7 science-backed techniques Choose 4-7-8, Box, Coherent, Long Exhale (4-8), Wim Hof, Physiological Sigh, or Alternate Nostril. Tap the info button on a technique to read what it does and the research behind it.
🫧
Long Exhale (4-8) — the gentlest one Breathe in through the nose for 4 seconds, then out for 8 through pursed lips — as if cooling a hot spoon — which is what keeps the out-breath slow and even. Six cycles, tagged “Wind down”. There are no breath holds at any point, so it is the easiest one to try first or to use lying in bed.
🔊
Sound cues — breathe with eyes closed Tap the Sound button to hear a real breath play as you inhale and exhale, with a short bip marking the end of each phase. Holds stay silent. Now you can follow along without looking at the screen.
⚙️
Pause & quick settings Tap the ⏸ button to pause the exercise, or the ⚙ button for quick settings — toggle the breath Sound, the background Music, and a Mini player so your song stays in reach.

Pomodoro — focus timer

A focus timer that runs over your music — free for everyone, no account needed. Turn it on in Settings → Pomodoro, then open Sleep Mode and tap the 🍅 Pomodoro card. The outer ring counts the round down, the inner one is the song playing underneath, and the next unchecked item from your to-do list rides along on screen.

25/5
Pick your rhythm 25/5 is the classic — 25 minutes of focus, 5 of break — and 50/10 is for longer blocks. Every fourth round earns a longer break (15 minutes; on 50/10 it is every third round and 20 minutes). Tap Custom and the − / + steppers let you set all four numbers yourself: focus, break, long break, and how many rounds earn one.
∞
Flow — no fixed round Tap Flow and focus counts up instead of down — it runs until you tap ☕ Take a break. The break is then worked out from how long you actually went (a fifth of it, never under 5 or over 30 minutes). Use it for work that a 25-minute cut keeps interrupting.
⚙️
Auto-start & alerts Auto-start next phase is on by default, so focus and breaks flow into each other. Untick it and the clock waits at 0:00 with a ▶ button until you are ready. Alert me when a phase ends adds a notification on top of the alarm sound — worth it when the tab sits in the background, where a browser can mute its audio. Your browser asks permission once; refuse it and the box simply unticks itself.
🔥
Streak & your last seven days Every finished focus round counts. Tap ✓ Finish to end the session and see rounds today, your day streak, your all-time total, and a seven-day bar chart of the rounds you ran. All of it works signed out, kept on this device — sign in and the streak follows you to every device you focus from.

Party Light Show

Turn the screen into a full-screen light show synced to the vibe. In Sleep Mode, tap the Party card to launch 11 effects — including a strobing Blitz mode and a packed Insane mode. Set the intensity, and drop your own custom text in the center with size and color controls. Great as a second-screen visual at a party while your playlist plays.

Rhythm games — Typo & Shooter

Two quick arcade games that play over your music. Open Sleep Mode and tap a card to start — your best score is kept on the leaderboard.

⌨️
Typo — type the falling words Type each word before it reaches the bottom. You're scored on speed and accuracy. When lyrics are available, the words can come from the song you're playing.
🎯
Shooter — tap on the beat Targets fly in to the beat — tap to shoot them before they pass, and chain hits for combo multipliers. Any track becomes a playable level.

Constellation — trace the stars

A calm star-tracing game in Sleep Mode. Open Sleep Mode (moon icon) and tap Constellation, then pick how you want to play. Your rank and collection are kept on this device — no account needed.

HUNT
Hunt — find the hidden shape You get a constellation's name and a tiny FIND THIS poster in the corner. The real stars hide among look-alike decoys — tap the right ones to trace the figure. More decoys appear as your collection grows.
SLEEP
Sleep — calm & no-fail The next star gently breathes — just follow it. No timer, no misses, made for drifting off.
PUZZLE
Puzzle — memorize, then rebuild Watch the lit shape for a moment, then rebuild it from memory once the stars go dark.
✦
Score, ranks & the 88 collection The big number counts every star tap (e.g. “4/4”). Finish clean — exactly the star count in Hunt, no wrong pairs in Puzzle — to earn an XP bonus; a sloppy finish still reveals the constellation but skips the bonus. XP builds a named rank (Stargazer → Cosmographer), and each first-time finish banks toward “X / 88 discovered” with a one-time First light bonus.

At the reveal you see the constellation's name, a short fact, and its myth — the story behind the figure. It holds a little longer so you can read it; tap Skip to jump ahead. Tap any discovered constellation in your collection to re-read its story. Want a harder Hunt? Pause and turn off the Reference poster in Settings to hide the FIND THIS outline.

Dropbeat — blocks on the beat

A falling-blocks game where the pieces drop on the beat. Open Sleep Mode (moon icon) and tap Dropbeat, then pick a vibe to start. Move and rotate the pieces to clear full rows — your best score is kept on the leaderboard.

🎵
Pick a vibe — it sets music & tempo Choose Ambient, Lo-Fi, Hip-Hop, Pop, Electro, or Rock. Your pick sets both the background playlist and how fast the blocks fall — Ambient is the calmest, Rock the fastest.
⚙️
Pause & quick settings Tap ⏸ to pause, then the ⚙ button for quick settings — toggle the game Sound, the background Music, and a Mini player so your song stays in reach.

Gems — match three

A match-3 puzzle over your music. Open Sleep Mode (moon icon) and tap Gems. Swap two neighbouring gems to line up 3 or more of a colour — they pop, the board cascades, and chains build into combos. Match 4 clears a whole line; match 5 makes a colour-bomb.

TIMED
Timed — 60-second score attack Score as high as you can in 60 seconds — your best run is kept on the leaderboard.
ENDLESS
Endless — play with no clock Keep matching for as long as you like, no timer pushing you.
ZEN
Zen — calm & no pressure A relaxed mode for winding down — just swap and watch the gems cascade.

Why don't I always see ads?

Ad display is controlled entirely by YouTube — based on the video owner's monetization settings, autoplay behavior, your region, and your YouTube account. Mixtuby does not block ads. They may appear at any time.

How do I listen with the screen locked?

Background playback depends on your device and browser, not just on Mixtuby. On iOS, embedded players pause when the screen locks — YouTube Premium does not change this for third-party sites. On desktop and many Android setups, if you're signed in to YouTube in the same browser, playback can continue in the background. Lock-screen and Bluetooth controls work whenever the browser allows it. For guaranteed screen-off listening, keep the screen on (Focus mode) or use the official YouTube app.

Control from your car, lock screen & Bluetooth

Mixtuby talks to your device's built-in media controls — so you can skip tracks without touching the screen. Perfect for driving, the gym, or pocket listening.

🚗
Car & Bluetooth buttons Steering-wheel, infotainment, and earbud/headphone next/previous and play/pause buttons control Mixtuby directly.
🔒
Title & artwork on display The lock screen and car display show the current track title and artwork, with skip and pause controls.
🎙️
"Hey Google, next track" / Siri Use Google Assistant on Android or Siri Now Playing on iOS to skip tracks by voice. (This is your phone's assistant — Mixtuby has no built-in voice command.)

With the screen on and Mixtuby in the foreground, these controls work for everyone. The real hands-free case — screen off or phone in your pocket — depends on your device and browser, not on Mixtuby (see "How do I listen with the screen locked?" above).

Ask your browser's AI to play music

If your browser has a built-in AI assistant (like Gemini in newer Chrome), Mixtuby teaches it a few tricks. Just ask in plain words — “play some focus music” or “search Mixtuby for Adele” — and the assistant can do it for you, hands-free.

🔎
Search & browse, hands-free Your assistant can search Mixtuby's catalog, list the curated playlists, or check what's trending — and read the results back to you, without you tapping anything.
▶
Start a playlist or a Vibe tool Ask it to play a curated playlist or open a Vibe Mode tool (Karaoke, Breathe, Party…) and it opens Mixtuby right on what you asked for.
NOTE
No AI in your browser? Nothing changes This only works if your own browser has a compatible AI assistant. On every other browser Mixtuby behaves exactly as before — nothing is added, removed, or sent anywhere. The assistant runs inside your browser; Mixtuby just lets it search our own catalog and open links for you.

You're offline

Playback requires an internet connection. Your playlist and position are saved — music will resume automatically when you're back online.
