Sealmate

Write a letter to your future self. Fully offline with no account, no server upload, and no cloud sync—open your message on the day you choose.

Sealmate is a letter to your future self.

Capture how you feel right now—words you want to say, plus an optional photo—and seal them gently. Open them on the day you choose. It is your own small ritual: no rush, no pressure, no interruption—just time returned to you.

You can use Sealmate to: · Write to your future self: for next year, for an anniversary, or for the day you return from a trip. · Hold your emotions safely: store hesitation, courage, longing, and blessings, then read them again later. · Mark meaningful moments: birthdays, graduation, new jobs, farewells, reunions—make opening itself a ritual.

What Sealmate offers: · Seal and unlock: set an unlock date, then let your message wait quietly. · Text and photos: keep pure text or add a photo to preserve both scene and tone. · Home & Lock Screen widgets: view your next upcoming message at a glance (optional). · Local reminders: receive a local notification on unlock day (optional, can be turned off in iOS Settings).

Privacy, by design: · Fully offline: no account, no server, no cloud sync. · Data under your control: uninstalling removes local data; you can also clear all data in-app. · Minimal permissions: photos are selected through the system picker; saving to Photos is write-only and only when you tap it after unlock.

Current limitation (to set clear expectations): · Device migration is not supported in the current version. Since there is no cloud sync, please save important content after unlock (e.g., Save Photo, Copy Text). If migration is added later, it will be announced in release notes.

Sealmate does not decide what you should say. It simply keeps time for you—so opening your message can become a meaningful moment in life.
