Privacy

Kartero stores the Google tokens of the Gmail accounts you connect, encrypted at rest (AES-256-GCM). It does not store your email: messages are fetched from Gmail when you or your authorized AI apps ask.

Kartero uses the Gmail gmail.modify scope to read, search, label, archive and draft, and gmail.settings.basic to read each account's addresses and signatures so drafts carry the right one. It keeps a copy of those signatures, encrypted like the tokens. It never sends, deletes or trashes mail, never changes your Gmail settings, and does not sell or share your data.

Email content is sent to the AI app you authorized (for example Claude), under that app's own terms.

You can disconnect any account, revoke any app, or delete your account and all stored data at any time from the dashboard.
