PearlNote

A journal that never phones home.

Why it exists

PearlNote is the smallest thing we ship and the one we are proudest of technically. There is no account, no sync server and no analytics SDK. Your entries are encrypted on the device and leave it only if you export them yourself.

That constraint shaped the product: streaks that forgive a missed day, a search that runs locally over years of text in under a hundred milliseconds, and a data export that is plain Markdown in a zip you can read in twenty years.

What makes it work

No account, no server

The app requests no network permission at all. There is nowhere for your journal to go.

Forgiving streaks

Habits track consistency over a rolling month instead of shaming a single missed evening.

Local search in under 100ms

Full-text search across years of entries, running entirely on device over encrypted storage.

Markdown you keep

One tap exports everything as plain Markdown and attachments in a zip. No lock-in, no proprietary format.
