Privacy Policy
Last updated 13 August 2026
I'm Samir. I make Vein on my own, under the name Abyssal Works, and I wrote this myself. It's short because there isn't much to say.
Vein is a music player for files you already have. Your songs, playlists, ratings, notes and listening history sit on your phone. They stay there. Nothing about your music goes anywhere unless you sign in and ask it to, and signing in is optional. If you never do, every section below about accounts and friends is simply not about you.
What stays on your phone
All of this lives on the device only, and goes when you uninstall:
- Your music files, plus the tags, artwork and lyrics inside them
- Playlists, likes, pins, ratings, private notes, the never-play list
- Listening history, play counts, statistics
- Settings, themes, the equalizer
If you sign in
Signing in goes through Google Sign-In and Firebase Authentication. What I get is your email address, your display name, your profile photo and a user ID. Your Google password never comes anywhere near me.
After that, these things live on Firebase under your account:
- Your profile. The handle, display name, status, bio and avatar you picked.
- Playlists you shared. Only the ones you marked as shared. The rest never leave your phone.
- Friends. Who you're connected to, and pending requests.
- Presence. What you're playing right now, if your sharing setting allows it, and only to whoever that setting names.
- Listening summaries. Your top songs and artists, if you set history sharing to friends or everyone. Set it to no one and nothing gets published.
- Notification tokens. So your phone can be told about a friend request or a change to a shared playlist.
You can turn any of it off in the app, and you can delete all of it. See Deleting your data.
Songs you back up
Your songs are never on my servers. Back one up and it goes into a folder called “Vein” in your own Google Drive, on your own storage, still yours. All Vein keeps is a note of the title, artist, length, and which file it is. Not the audio.
Vein asks Google for one permission there, called
drive.file. It covers files this app created and nothing
else. Vein can't see or list the rest of your Drive: not your documents,
not your photos, not music you put there yourself.
Songs backed up by an older version are still sitting in Firebase Cloud Storage, so they keep working. Delete any of them from Settings → your account → cloud library.
Things the app looks up online
A few features ask the internet a question. Those requests carry a song title, an artist name or whatever you typed, plus your IP address, which is unavoidable. They don't carry your name or your account.
- MusicBrainz fills in album, year and composer tags that are missing.
- LRCLIB finds lyrics.
- Deezer provides the charts, artist pages, thirty-second previews and suggestions.
- radio-browser.info is the station directory. Playing a station tells it that station got played, which is how the popularity list works. It isn't told who played it.
- The Podcast Index and Apple's directory answer podcast searches. Whichever answers gets the words you typed and nothing else.
- Podcast feeds and episodes come straight from whoever hosts them, so those hosts see the request the same way a browser would. Downloaded episodes are kept on your phone only — they are never uploaded to your cloud library.
Two more only happen if you set them up:
- Spotify. Connect it and Vein reads your listening history and library to fold into your stats, and can drive playback. Disconnect and that stops.
- ListenBrainz. Paste in a token and switch scrobbling on, and the songs you play get submitted to your ListenBrainz account. Off until you do both.
Private listening
There's a switch in the side menu that pauses the lot. While it's on, nothing goes into your history, nothing reaches your friends, nothing gets scrobbled.
What I don't do
- No ads, and no advertising identifiers.
- No analytics, no tracking SDKs. Nothing is measuring how you use the app.
- Nothing sold, nothing handed to data brokers.
- Crash reporting is switched off.
Children
Vein isn't aimed at children under 13, and I don't knowingly collect anything from them.
Deleting your data
In the app: Settings → Delete account. That removes your profile and handle, the playlists you shared, your friendships on both sides, your presence and listening summaries, your notification tokens, the Vein folder in your Drive, and the account itself. Permanently.
It doesn't touch anything on your phone. To clear that too, uninstall Vein or wipe its storage in Android settings.
Locked out of the app? Email samirabilhasanli@gmail.com from the address the account uses and I'll delete it for you. There's also a page about this.
How long I keep it
Until you delete it. There's no other retention rule, because there's no other use for any of it.
Where it's kept
The account side (profile, shared playlists, friendships, presence) is on Google Firebase: Authentication, Firestore and Cloud Messaging. Google may process that outside your country. Your songs are in your own Google Drive, under your own Google account.
If this changes
The date at the top changes and the app's release notes mention it.
