This page is for the app Libertylang, published by Mykhailo Ponochovnyi. It explains how to delete the data the app holds about you.
Libertylang has no accounts and no server of its own. Your name, settings, learning progress and everything you create live only on your phone.
If you switched statistics on, Firebase Analytics and Firebase Crashlytics (services of Google) hold anonymous usage events and crash reports tied to a pseudonymous installation identifier. They never contain your name, your texts or audio.
Uninstall the app: this erases all local data. To delete only part of it, remove the words, situations, topics or chats you created inside the app.
Turn off the switch “Share anonymous usage and crash data” on the Terms of use page (Settings → Help & feedback). The app then stops sending anything.
To delete statistics that were already sent, write to feedback@libertylang.com with the subject “Libertylang data deletion” and tell us your device model, your country and roughly when you installed the app, so we can find the installation. We delete the matching data in Firebase within 30 days and confirm by email.
Deleted on request: the usage events and crash reports linked to your installation identifier.
Kept: aggregated statistics without identifiers, for example how many people opened a screen; they cannot be linked to you.
Without a request, Crashlytics deletes crash reports after 90 days and Analytics deletes identifier-linked data after the retention period set in Firebase, at most 14 months.
