A real writing space
Bold, italics, lists and links. Properly formatted entries, with search across your whole journal, all on your device.
Use case
Write like no one will ever read it. Because no one can.
Honest journaling needs the certainty that it stays yours. Sealby is a diary with real encryption: entries with formatting, encrypted on your device, inside a vault that nothing on your phone points to.
What is the most private journaling app for iPhone?
The most private journal never leaves your device in readable form. Sealby encrypts entries with AES-256 before they are saved, needs no account, and keeps your journal inside a hidden vault. No one can stumble on it, nothing readable ever syncs out, and nothing records that it exists.
No one stumbles onto it
A journal in a notes app can be read by anyone who scrolls past it. A journal in a hidden vault stays out of sight, even from someone holding your unlocked phone.
Not a service, a vault
Journaling services hold your inner life on their servers. Sealby holds nothing: no account, no server, and no way for anyone, including us, to read a word.
Common questions
Is this more private than Apple’s Journal app or Day One?
Journal services and synced apps keep readable data or keys within reach of the provider or your cloud account. Sealby has no account. Entries are encrypted on your device with AES-256, and with Premium the only thing in iCloud is encrypted data no one can read.
Can I add photos to journal entries?
Yes. Keep photos, videos and files in the same vault as your entries. Everything is encrypted the same way and organized with folders and tags.
