Notenz

Notenz is an automated check-in service that acts as a safety net if something happens to you. You set a check-in interval from daily to monthly; if you miss it and don't respond during a grace period, Notenz notifies your trusted contacts and delivers your designated vault items, such as passwords, account access instructions, and final messages, to the recipients you chose.

Everything is encrypted at rest. For the most sensitive secrets like password manager master passwords, recovery codes, and crypto seed phrases, Guardian's Sealed Vault uses zero-knowledge encryption—encrypting in your browser with a password only you know, which Notenz never has and can never recover.
