FAQ

Does TKN see my API keys?
Your keys are encrypted on your device. In the local-only configuration they're never sent to us. If you enable background spend monitoring, encrypted keys are stored so we can poll your providers — see the Privacy Policy.

Will TKN stop every overcharge?
No tool can promise that. TKN is a fast second line of defense — keep your provider-side hard spend limits on too.

What does the kill switch do?
It revokes the API keys you've connected so dependent services stop authenticating. Revocation is irreversible — you'll reissue keys from your provider.

How do I cancel Pro?
Manage or cancel from your Apple ID subscription settings. Lifetime purchases don't renew.

Delete your account & data

You can remove your data at any time:

• In the app: Settings → Account → Delete Account. This permanently removes your account, stored settings, and any keys held for monitoring.
• Local data: deleting a key in the Vault, or uninstalling TKN, removes that data from your device.
• By email: write to support@gettkn.com from your account email and we'll delete everything within 30 days.

Deleting your TKN account does not revoke your provider keys — use the kill switch or your provider's dashboard for that.
