A real writing space
Bold, italics, strikethrough and headings. Properly formatted entries, with search across your whole journal, all on your device.
Use case
A private journal, encrypted on your device.
Write freely in rich-text entries encrypted on your device. Sealby stores no list or count of vaults. Lock your journal when you finish: an open vault, a known credential or an external copy can expose entries, and the app itself may still draw attention.
What is the most private journaling app for iPhone?
Look for encryption on your device and a separate vault credential. Sealby encrypts entries with AES-256 before saving them and stores no vault list or count. Keep the vault locked when not in use. Open content, known credentials and copies elsewhere remain outside that protection; no stored vault list does not mean no clues.
No stored list or count of other vaults
Lock the vault before handing over your phone. Opening another vault does not list or count the others, but an open journal, a known credential or an external copy can still expose your entries.
Not a service, a vault
Sealby requires no account and runs no servers for your content. That limits what Sealby holds; it does not remove data on your devices or in copies elsewhere, or determine what you may be required to provide.
Common questions
Is this more private than Apple’s Journal app or Day One?
Compare the encryption, account access and backup settings of the app you use. Sealby needs no account and encrypts entries on your device with AES-256. Premium can back up encrypted data to your iCloud. An open vault, a known credential or copies saved elsewhere remain outside the protection of a locked vault.
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.
