Delete your CardStacks account
In CardStacks, open Profile → Delete account. Sign in to the account you want to delete, review the consequences and confirm the request. Version 3.0 requires a registered account. Older versions that support guest accounts provide guest deletion on the original device; contact feedback@cardstacks.xyz if an older account is inaccessible.
You can also open account deletion in the web app. You do not need to install the mobile app.
What is removed
The deletion scope includes your login account, linked identities, private stacks and legacy card rows, saved practice, statistics, account-linked purchase access and account-linked promotion records.
Store purchases are not automatically refunded. Purchase access linked to an account cannot be transferred to a different CardStacks account. Keep your store receipts.
Current availability and retained copies
The authenticated request service accepts confirmed requests and returns a pending receipt. Use an updated CardStacks release that includes the deletion flow. A queued request preserves the account and data; its receipt does not mean deletion is complete. Completion handling and timing are not yet verified.
Protected migration copies and backups still exist. Their deletion or lawful retention must be accounted for before the service can report complete deletion. We do not promise an unverified backup removal period.
If deletion cannot finish, the app shows an error. Some active data may already have been removed; retry rather than assuming the whole account was deleted.
For questions about existing copies or retention, contact feedback@cardstacks.xyz. Contacting support is not intended to replace the authenticated in-app deletion flow.
