Contact TaKnow
Send a support request
The secure request form opens in a new page. You can also use Profile → Settings → Feedback inside the app. The form is hosted by Feishu/Lark and processes the details you choose to submit as described in the Privacy Policy.
If you cannot continue under the adult policy
You can use this public page without signing in or passing age screening. Request access to or export of existing account data, ask for deletion, or report an account belonging to an ineligible person. We may need to verify account ownership before acting. An eligibility restriction does not automatically delete your account or cancel an Apple subscription. Manage subscriptions in your Apple account and request refunds through Apple's refund service.
Delete your account in the app
Open Profile → Settings → Delete Account. No support request is required. Deletion is permanent and removes your authentication account and related TaKnow content. See the account deletion guide for step-by-step instructions and the Privacy Policy for details.
