To receive it sealed, yes. When you send a sealed letter to someone else, their Lettera holds it closed and opens it in wax on the morning you chose — that ceremony only exists inside the app. So for the full experience, they need the free app (on the day, or beforehand). You can send them the App Store link with the letter.

If they don’t have the app, you’re not stuck. On the arrival day, your own desk hands you the letter rendered as a finished page — a picture you can send by Messages, email, or print — that anyone can read, no app required. The sealed file is for app-to-app; the paper version is for everyone else.

A sealed .lettera file is meant to be opened by Lettera. In the current App Store version, some share destinations and file previews can show the text carried inside instead of presenting it as a document. Inside Lettera, the same file opens as a properly sealed letter on its chosen day.

If a sharing app puts the contents into a message instead of attaching the .lettera document, cancel before sending. Save the file to Files and attach the document, or use AirDrop to another person with Lettera. Remember that the wax is ceremonial rather than encryption, as explained below.

The wax is a promise, not a lock. Inside your own device the letter is held closed until its day. But a sealed .lettera file you send to someone is readable by a determined person who has the file — it is carried in good faith, the way a wax seal always was. Don’t put in a shared letter anything that would harm you if it were opened early.

Never. Open the app and write. There is no sign-up, no email, no password — nothing to forget and nothing for us to lose.

In the app’s private space on your device. If you turn on “Keep a copy in iCloud,” Lettera also mirrors the archive in Apple’s private CloudKit database under your Apple account. Apple may separately include app data in your iCloud or computer device backup, depending on your backup settings. Mama Bloom operates no sync server and cannot access any of those copies.

Deleting the app removes its on-device archive. If a private iCloud copy still exists, reinstalling Lettera under the same Apple account and turning sync back on can bring that archive back. A device backup may also restore app data. Without an iCloud copy, backup or export, the on-device archive is gone. Before deleting, use Export to save a copy you control.

No. Sealing is deliberate and final — that’s the whole point. It keeps you honest with the person you’ll be when it arrives. Write in that spirit; nothing forces you to seal before you’re ready.

On a calm day you write short letters to the you inside Anger, Dread, Grief, Overwhelm, Sleepless nights, or Doubt. In a hard moment you tap the storm you’re in, and your own earlier voice answers — with a matched passage from the ancients beneath it. No AI counsellor. The wisest person about your 2 a.m. is you, three weeks ago.

No. If you ask for a suggested first line on a supported device, that runs on-device with Apple Intelligence and sees only the letter you’re writing, not your archive. Lettera does not send the writing to Mama Bloom or to a cloud AI service.

The core app is free forever. Patron is an optional subscription (monthly or yearly) shown at your App Store’s price for your region. There’s no free trial — the free app never expires, so nothing can bill you for one you forgot. Cancel anytime in your Apple account; your letters are untouched either way.

On your iPhone or iPad: Settings → [your name] → Subscriptions → Lettera → Cancel. Billing is handled by Apple, so cancellation and refunds go through your Apple account, not through us.

English, German, French, Spanish and Japanese. The interface and all forty letters in Season One are available in all five. Lettera follows the app-language preference set by your Apple device; the Apple Watch companion follows the language set for the Watch.

iPhone, iPad and Apple Watch. The full correspondence desk lives on iPhone and iPad. The Watch companion is a brief, private pause; personal letters and arrivals stay off the wrist.

Arrival alerts are scheduled locally on your device and only ever say a letter has arrived — never a word of its contents. Nothing about your writing travels over a network to deliver them.

In the quiet corner, Export writes the correspondence archive to a readable file in a location you choose. Exporting does not remove the archive from Lettera or iCloud.

Erase every copy first connects to your private iCloud and removes Lettera’s CloudKit mirror, even if ordinary sync is off, and then clears the archive on the device. If iCloud cannot be reached, Lettera erases nothing and asks you to try again rather than leaving an old copy behind. Turning sync off by itself does not delete an existing iCloud copy. You can also remove Lettera data through Apple’s iCloud storage controls. Export first if you want a copy to keep.

You can write, seal, receive and read without a connection. A network is used only for features you choose that need one: private iCloud sync, buying or restoring Patron, or a sharing service such as Messages or Mail.
