About Future Letter: Time Capsule

Future Letter is a time-locked letter app — write something now, and it stays completely sealed until the date you choose.

Choose who it's for: yourself, a partner, a spouse, or a friend. A letter to open on your anniversary. A letter to yourself one year from now. A letter for a niece to open when she graduates. No one can open it before that date — not even you.

- Letters to yourself are encrypted and kept only on this device.
- Letters to someone else are shared as a single code. Once they register it in this app, it unlocks only on the date you chose — on their own device.
- No server, no account. Every letter is encrypted locally, on your device only.
- Forgot your app PIN? You can still recover everything from a backup.

This isn't a lock — it's a promise. Changing your device clock might open it early, but that would just be lying to your future self (or to the person you wrote it for).

An anniversary letter. A letter your child opens when they grow up. A promise to your future self, one year from now. Future Letter keeps today's words safe until the day they're meant to arrive.
