An account in SineO is needed for the watchlist only; the rest of the app works without one. If you never signed in, there is no account to delete — this page is for people who did.
This is the fastest way and it is the same on both platforms: Settings → Account → Delete account. After you confirm, the account and anything synced with it are removed.
For safety, Firebase can ask for a recent sign-in before deleting. If you see that notice, sign out and back in from the same screen, then delete again.
Lost the phone, or already removed the app? Ask by e-mail: mustafa@mustafaevleksiz.com. Put "SineO account deletion" in the subject and tell me the address you signed in with.
If you hid your address with Sign in with Apple, give the @privaterelay.appleid.com address you were issued — that is how I find the account. Requests are completed within 30 days, usually within a few, and I write back to the same address.
A deletion request removes all of this:
Sync carries identity and time only — never a name, poster or rating — so there is no copy of those to delete.
The list on your phone stays where it is: deleting the account does not empty the app. If you want everything on the device gone as well, removing the app is enough — SineO keeps no other record off your device.
We hold no backup of our own. A deletion takes effect immediately; transient copies inside Google's infrastructure fall away on their own schedule.
You can sign in again at any time after deleting. The new account starts empty: the deleted sync record does not come back.
