Stash
your Spotify + YouTube Music library, on your phone or browser
Stash grabs your Spotify and YouTube Music playlists and mirrors them on your Android phone. Download them, stream them, mix and match. Hi-res when it exists.
No Stash account, no analytics, your logins stay on your phone. Free and open source, forever.

Install
Easiest: grab Stash.apk from the latest release, open it, tap Install. If Android grumbles about unknown sources, allow it for your browser and try again.
Want auto-updates? Use Obtainium and add https://github.com/rawnaldclark/Stash. It'll ping you when there's a new version.
You need Android 8.0 or newer, and a Spotify and/or YouTube Music account.
Build it yourself
git clone https://github.com/rawnaldclark/Stash.git
cd Stash
./gradlew assembleDebug
# APK lands in app/build/outputs/apk/debug/
You'll need Android Studio Hedgehog (2023.1.1) or later, JDK 17, and Android SDK 35. A build from a plain checkout skips the project's lossless relay and Last.fm proxy. CONTRIBUTING.md has the rest.
First-time setup
Open Settings, tap Spotify or YouTube Music under Accounts, tap Connect and sign in like normal. That's it. Then hit the Sync tab, pick the playlists and mixes you want, and tap Sync Now.
The first sync is the slow one (a big library with Download on can take an hour). After that it only grabs what's new. Turn on Auto-sync and forget about it.
Stash doesn't use Spotify's or YouTube's official APIs, because they don't let apps like this exist. It uses your login instead, the same way your browser does. Your login stays on your phone, encrypted, and only ever goes back to Spotify or YouTube.

Same incognito tip as Spotify.
🎮 Discord status (read this first)
Discord has no official way for a phone app to show what you're playing, so Stash does it through your own account's session (the same trick PreMiD and similar tools use). It's not a bot and it only sets your status.
Heads up: Discord calls this kind of thing a self-bot in its Platform Manipulation Policy, and its support article says it can get an account banned. In practice they go after spam, not music statuses, so the risk is low. But it's your account, so it's your call. The app asks before connecting, and everything else in Stash works fine without it.
To connect: Settings → Discord → Connect, and sign in. If that fails, tap Paste token: sign in at discord.com/login on a computer, open DevTools (F12) → Application → Local Storage → https://discord.com, and copy the token value.
Disconnecting clears your status right away and deletes the token from your phone.
FAQ
Download or stream, what's the difference?
Flip Download on (Sync tab) and your playlists get saved to your phone so they play with no signal. Leave it off and they stream, taking almost no space. Either way, any single playlist has its own Download button. Stream on mobile data by turning on Stream on cellular in Settings.
Where does the FLAC come from?
Qobuz and Tidal. Stash looks every song up there. If you have a Qobuz account you can connect it in Settings and it uses yours. If not, it uses the project's relays, which hand your phone a link and the audio comes straight from Qobuz or Tidal. Everyone gets 500 lossless songs a day, which is a lot. No lossless copy? It plays AAC or Opus instead, and Now Playing tells you where it came from. The full details are in PRIVACY.md.
Is my login safe?
Your logins live on your phone, encrypted, and only ever get sent back to the service they came from. There's no Stash server holding your stuff and no analytics. Want every single host Stash talks to and why? It's all in PRIVACY.md. Yes, all of it.
Why isn't it on the Play Store?
Google Play doesn't allow apps that save audio from YouTube. So it lives here.
Stash never downloads audio from Spotify. It reads your Spotify library with your login and finds each song somewhere else. It isn't affiliated with any of the services it connects to, and you're responsible for how you use it.
Sync keeps stopping in the background
Some phones (looking at you, Samsung, Xiaomi, OnePlus, Huawei) kill apps to save battery. Go to phone Settings → Apps → Stash → Battery and set it to Unrestricted. Still dying? dontkillmyapp.com has a fix for your exact phone.
