Delete your app account

Request deletion without the app

Email support@stacklab.com with the subject “Account deletion — KanjiYama” (or the name of your other StackLab app). Include the account email and sign-in provider so we can locate the correct account. You do not need to reinstall the app. We may verify ownership before completing the request. We will respond with the next steps and expected completion time.

Never send passwords, authentication codes, or full payment-card details.

In-app deletion steps

1. Open the app.
2. Open Settings or Account.
3. Select Delete Account.
4. Review the notice.
5. Confirm deletion.

If you cannot access the app or your account, support can assist at support@stacklab.com. Sending an email does not automatically complete deletion; identity or account verification may be required to protect the account.

What is removed or retained?

For KanjiYama, deletion removes your Firebase Authentication account and private account profile. In-app deletion also clears learning history on that device. An email request cannot remotely erase offline learning data on your devices or their backups; use Reset learning progress or remove local app data there. Purchase/security records needed for fraud prevention, refunds, or legal obligations may be retained; store records are controlled by the store.

Deleting your account or app does not cancel a subscription. Manage or cancel it through the store where you purchased it. Cancellation is not a prerequisite for requesting account deletion.
