Who publishes Sostina
The Sostina app and this website are published by Hassan Yassine, an individual developer. Hassan Yassine is the publisher responsible for this privacy notice and the contact for any question about it.
The app
What stays on your phone, and only there:
- Your settings: the noise and voicing you chose, Boost and Persist.
- The night log: start and stop times and any interruptions, used to show the morning receipt.
- While Persist is on: a copy of your Do Not Disturb settings, so they can be put back exactly when you stop.
The app opts out of Android’s cloud backup, so this data is not copied to your Google account. Uninstalling Sostina deletes it.
Permissions and why
- Foreground service, media playback and wake lock: to keep the sound playing all night with the screen off.
- Notifications: for the playback notification with its Stop button.
- Ignore battery optimisations: to ask Android, with your permission, not to close Sostina overnight.
- Do Not Disturb access: only for Persist, and only if you grant it in Android settings.
Sostina does not request internet, location, microphone, contacts or storage access.
