Delete your account and data

Applies to Daily Killer Sudoku (app.fatmika.sumdoku)

SumDoku creates an anonymous account automatically so your progress survives reinstalls. You can delete that account — and everything tied to it — at any time.

How to request deletion

Email contact@fatmika.com with the subject "Delete my SumDoku account".

• If you signed in with an email code, send the request from (or mention) that email address so we can find the account.
• If you never signed in (anonymous account), open the app, go to Settings, and include the information shown there so we can identify your account — or simply uninstall the app: an anonymous account that is never used again is deleted automatically after 12 months of inactivity.

What gets deleted

Everything tied to the account, within 14 days of the request:

• Solve history (times, errors, hints, dates) and streak data
• Profile row (display preferences, active mascot/theme)
• Push notification token
• The account itself (Supabase auth user)

Purchase state lives with RevenueCat and your Google Play account; refunds and purchase management happen through Google Play.

Data kept

None. We keep no analytics, no advertising identifiers, and no marketing lists, so there is nothing else to remove. See the full privacy policy.
