Unletter wax seal

Seal a letter
to the future.

Write a letter, add a photo or your voice, and seal it with wax. Pick a day, and no one can open it until then. Three months, six months, a year, or further into the future — a notification quietly arrives.

Write & Seal

Write a letter,
seal it with wax.

Add photos or your voice to your message, then seal the envelope with wax. Once you pick an open day, no one can see inside until that day arrives.

“To someone dear” does not send the letter to them. It stays in your Unletter so you can open it together on the same device.

The Day Comes

When the day comes,
a notification arrives.

Three months, six months, a year, or further into the future — a notification reaches you on the day you chose. Break the seal, open the envelope, and meet your letter again.

A note, always visible before opening, holds the promise — when, where, and with whom to open it.

One of a Kind

A wax seal that is
never the same twice.

Every time you seal a letter, a wax seal is born that is never the same twice in color or shape. A special seal for your letter alone.

Your letters line up in the “Letterbox,” and you can gather your wax seals. A quiet little collection that grows with you.

Safely Kept

Safer storage
for every letter.

Your letters are saved and synced with your own private iCloud database. Unletter also keeps an integrity-checked copy on this device.

If iCloud is temporarily unavailable or its settings change, Unletter does not replace your letters with an empty Letterbox. It leaves the data unchanged and guides you through what to check.

FAQ

 

Can I change the open day after sealing a letter?
Once a letter is sealed, its contents stay hidden until the open day. You can freely edit a letter any time before you seal it.
Can I only choose one of the four suggested opening dates?
No. Three months, six months, one year, and three years are one-tap suggestions. You can also choose any future date and time, down to the minute—tonight, next week, or 20 years from now.
Where is my data stored? Does it survive switching phones?
Your letters are kept in your private iCloud database and sync across devices signed in with the same Apple Account. Unletter also keeps an integrity-checked copy on this device. Letters already saved in iCloud can sync back after reinstalling with the same Apple Account. The device copy is in the App’s private container and is removed if you delete the App. The developer cannot access the contents of your letters.
My letters suddenly disappeared
If you sign out of iCloud, switch to a different Apple Account, or turn off iCloud for Unletter, the App does not present an empty Letterbox in place of your letters. It leaves letter data unchanged and guides you through what to check. Make sure you are signed in with the Apple Account you used to write the letters and that Unletter is enabled in iCloud. If the issue remains, contact us below.
Can I send a “to someone dear” letter to them?
No. “To someone dear” keeps the letter in your Unletter so you can open it together on the same device on the day you choose. It does not deliver the letter to another person’s device.
Is the wax seal different for each letter?
Yes. Every time you seal a letter, a wax seal is born that is never the same twice in color or shape.
How long can a voice message be?
With Pro, new voice recordings can be up to 3 minutes. Recordings longer than 3 minutes that were already saved in an earlier version remain protected without being shortened or deleted.
What’s the difference between Free and Pro?
The free plan lets you create up to 3 letters, with 1 photo per letter. Pro unlocks unlimited letters, new voice recordings up to 3 minutes, and up to 4 photos per letter. One purchase, yours forever.
