Delete your account and data

Last updated: September 28, 2026

This page explains how to ask us to delete your Tactiq account and the data stored with it, what exactly is removed, and how long it takes. It covers the Tactiq app for Android and this website, and it is part of our Privacy Policy.

How to send a request

Email tactiq.chess.app@gmail.com with the subject Data Deletion Request, ideally from the address you signed in with, and tell us what should be removed:

• The whole account. The account and everything stored under it is deleted.
• Only part of the data. Name what should go — for example your leaderboard entries, the feedback you sent us, or your cloud progress — and the account stays open.

If the request comes from a different address, we may ask you to confirm that the account is yours before deleting anything. We never ask for your password and we do not need any payment details.

What we delete

• The sign-in account itself, including the email address, name and profile picture received from Google Sign-In.
• Cloud progress stored under your account: solved-puzzle history, training progress by theme, and your statistics.
• Your entries in the seasonal and global leaderboards.
• Feedback you sent from the app. It is stored with your account id, the app version and the device model.
• Technical records tied to your account, such as request limits and synchronisation markers.

What a deletion request does not cover

• Data on your device. Progress, settings and downloaded puzzle databases are kept on the phone itself. Uninstalling the app removes them, and you can also clear them in the Android settings (usually Settings → Apps → Tactiq → Storage → Clear storage). We have no access to that copy.
• Progress on this website. Puzzles you solve here are recorded in your browser’s local storage and never reach us. Clearing site data for tactiqchess.com in your browser removes them.
• Subscriptions and payments. These are handled by Google Play, not by us. Deleting your account does not cancel a subscription — manage it in Google Play subscriptions. Refunds also go through Google Play.
• Anonymous statistics that are not linked to your identity, copies inside backups until those backups rotate out, and anything we are required to keep by law.

How long it takes

We confirm the request by email and delete the data from our active databases within 30 days.

Playing without an account

The app can be used without signing in, and this website needs no account at all. In that case nothing is linked to your identity and there is nothing to request: uninstalling the app, or clearing your browser data, is enough.
