Account & Recovery

Cynosure uses end-to-end encryption. Your recovery phrase is the only way to access your encrypted data — if you lose it, no one (including A3RN) can recover your data.

Delete Your Account

You can delete your account at any time from Settings in the Cynosure iOS, Android, or web app — sign in, open Settings, and submit a delete request. This permanently removes all your data from our servers.
