The short version. Your tab files never leave your phone. Tabline has no account, no login and no server of its own. It sends anonymous usage events and crash reports so the app can be fixed and improved, and nothing that identifies you.
Every score you open, read or play is processed entirely on your device. Tabline contains no HTTP client at all, so it cannot upload a score file anywhere, and it keeps no copies of them, and has no ability to read them once you close the app.
Tabline asks for no storage permission. It reads a file only when you hand it one — through the system file picker, through "Open with" from another app, or through a share. Android grants access to that specific file, and Tabline keeps that grant only so a design in your Recents list opens again later. You can revoke it at any time in Android's settings.
Tabline writes nothing back: it opens a file, draws it and plays it. The only thing it remembers about a score is its name, its track count and where you were in it, so the Recent list can take you back.
Tabline uses Google Firebase Analytics and Google Play's billing service. Between them these record:
There is no advertising in Tabline, and no advertising or tracking network is embedded in it.
Analytics events are retained by Firebase according to the project's configured window and are aggregated. Purchase records are retained for as long as the purchase is valid, which for a one-time unlock is indefinitely, so the unlock can be restored on a new phone.
You can stop collection at any time by revoking the app's data sharing in Android's settings, or by uninstalling Tabline.
To have the records associated with your install deleted, email machadowg@gmail.com from any address, with the subject “Tabline data deletion”. Say which app you mean (Tabline, by machado001) and, if you have it, your RevenueCat app-user ID. You do not need an account, because Tabline does not have one.
What gets deleted: the anonymous usage events, the crash reports, the device and app basics (app version, device model, operating-system version, country) and the resettable app-instance identifier tied to that install, and the record of your one-time unlock. Requests are answered within 30 days.
What cannot be deleted, because it was never collected: your tab files and anything derived from them, your name, email address, phone number or contacts, your precise location, and your photos. None of it ever leaves your phone.
Deleting the record of your unlock also gives up your ability to restore that purchase on a new phone. Google Play keeps its own record of the transaction under Google's terms, and that is not ours to erase.
Tabline is a tool for guitarists reading their own tab files and is not directed at children under 13. It collects no personal information from anyone.
If this policy changes materially, the date at the top changes and the updated policy appears here before the change takes effect in the app.
