Deleting your account and data
In line with Google Play's and the App Store's account-deletion requirements, any user of Matura na 100 (published by LogicLoom Kamil Zwarycz) can request permanent deletion of their account and associated personal data — without needing to reinstall the app.
Settings → Account → “Usuń konto” (Delete account, the app's UI is Polish-only). Premium access is revoked immediately, login sessions are invalidated right away, and data is permanently and irreversibly deleted after a 30-day window to withdraw the request.
Send an account/data deletion request from the e-mail address associated with your account to:
privacy@matura-na-100.plWe respond and start deletion without undue delay, no later than one month after the request (GDPR Art. 12(3)).
Deleted on request: account and profile data, learning progress (SRS history, answers, badges), essays, diagnostic sessions, and mock-exam results. Details: Privacy Policy.
