Terms of use

Last updated: 2026-10-19. Operated by nikolaisen.org.

By using lastknow.com you agree to these terms and the acceptable use policy.

What this is

A check-in and delayed-send service. You write letters or last wishes, optionally attach files, and name who should receive them if you miss check-in or on a date you set. Optional latest-status notes go only to people you invite as watchers.

Your content

You keep ownership of letters, files, and status notes. You grant us a licence to store them and to send them exactly as you instructed (to named recipients or watchers). Cancel or emergency-stop before send if you change your mind. Once a recipient has opened a link, we cannot take the words back.

Who may use this

You must be at least 18 years old to use this service. It is not intended for children. If you are under 18, do not use it. We do not knowingly collect personal information from anyone under 18, and we will delete an account and its contents if we learn one belongs to someone under 18.

Accounts

You are responsible for the email, password, ping PIN, and API token on the account. We may suspend or delete accounts that break the AUP or the law.

No warranty

The service is provided as-is. Mail can fail, cron can miss, a host can go down. Do not rely on this as your only plan for documents or family notice.
