# Sign out or delete your account

Use **Log Out** to end the current sign-in. Use **Delete Account** only when you intend to permanently remove the account and its study data.

## Log out

1. Finish or save any active card edits and AI drafts.
2. Open **Settings**, then the account card to reach **Account Info**.
3. Tap **Log Out** and confirm the **Log Out?** dialog.
4. Wait for the sign-in screen.

The local study profile remains on that installation. Signing back in to the same Flashnerd account reopens it. Logging out is not a backup operation, and signing in with a different account opens that account's separate profile.

To switch accounts, log out and choose the intended provider account on the sign-in screen. Use [linked sign-in methods](https://docs.flashnerd.com/guide/accounts/sign-in.md) when you want Apple and Google to access one Flashnerd account.

## Delete an account

:::danger
Account deletion permanently removes the account and its study data, including decks, cards, review history, and statistics. It cannot be undone through the app. Export a backup first if you want to keep a copy of your study material.
:::

1. While signed in, [export your collection](https://docs.flashnerd.com/guide/import-export/backups.md) if you want to retain study content.
2. Open **Settings → Account Info** and verify the account being removed.
3. Tap **Delete Account** and read the confirmation.
4. Complete any requested Apple or Google verification using a method linked to this same account.
5. Confirm deletion and wait for the app to return to the sign-in screen.

A backup preserves selected study content, not the deleted account's credentials or identity. It is not a way to reverse account deletion.

## If verification or deletion fails

Use the same linked account when verifying. Signing in with a different provider identity cannot authorize deletion of the active account. On iPhone, if Apple verification fails and Google is linked, the app may offer **Try Google**.

Check your connection and retry the reported operation. Do not clear app storage to fix an uncertain deletion result; reopen the app online so it can resolve the account state. If the error persists, [contact support](https://docs.flashnerd.com/help/contact.md) with the error message and steps taken.

For offline restrictions and retained profiles, see [Local data and offline use](https://docs.flashnerd.com/guide/accounts/offline-and-data.md).
