Delete your One Line account and data

1. Delete from your browser

This page is enough: you do not need to install or reinstall One Line to delete your account. The button below opens the One Line sign-in page in your browser, then takes you straight to the Account section of Settings, where the deletion action lives.

1. Select “Sign in and delete my account”.
2. Sign in with the same method you use in the app (email or Google).
3. In the Account section, choose “Delete my account”.
4. Read the summary, type DELETE to confirm, then submit.

2. Delete from the app

If One Line is installed on your device, the path is the same and requires no contact with support:

1. Open One Line and sign in to your account.
2. Open Settings.
3. In the Account section, tap “Delete my account”.
4. Type DELETE in the confirmation field, then submit.

An internet connection is required, because the server must confirm the deletion before local data is erased.

3. What is deleted

Deletion permanently removes:

• the account itself, your email address and your sign-in sessions;
• your profile, display name and synced preferences;
• your synced progress, solutions and Daily Challenge results;
• your hints, rewards and hint events;
• your packs and the entitlements attached to your account;
• your leaderboard entries;
• your feedback, comments, ratings and reports;
• the local identities linked to your account and their encrypted backups;
• the community worlds you published, with their revisions and levels;
• your duel participation, results and statistics;
• the referral relationships that identify you;
• the local One Line data on the device making the request.

Other devices still signed in to that account reset themselves on their next launch or next sync.

4. What may be kept

In normal operation, only the following three categories may remain. None stays linked to your account, name or email address:

• A fingerprint of your former local identities. To prevent an old offline installation from restoring deleted progress, One Line keeps a one-way SHA-256 hash of each deleted local identifier, with its date. This record contains no email, no name, no account id and no plaintext local identifier, and exists only to enforce the deletion.
• Data belonging to other players. A duel you took part in still exists for your opponent, but your participation, results and statistics are removed from it and you are no longer named. Hints already granted to someone else through a referral remain theirs.
• Genuinely anonymous analytics, meaning aggregate measurements that cannot be linked back to your account or your device.

Some data may also have to be kept where the law requires it. Details are described in the privacy policy.

5. Timing and effects

Deletion is immediate and irreversible: there is no grace period, no restore option. The self-service path requires no manual processing. Once it completes, the account can no longer be signed in to and the synced progress cannot be recovered.

Deleting your One Line account does not delete your Google account and does not cancel purchases made through Google Play. You can keep playing immediately with fresh local progress, as after a first install.

6. If you can no longer sign in

If you have lost access to your account, email max.manseau01@gmail.com from the address associated with the account, including the display name used in One Line. Reasonable identity verification is required before any manual deletion, so that nobody can have another player’s account deleted. Requests are handled within a reasonable time.
