Leafmark — Privacy Policy

Last updated: June 11, 2026

Leafmark is built on a simple principle: your books, highlights, and reading habits belong to you — and to no one else, including us.

What we collect

Nothing.

• No account. You never sign up, log in, or give us an email address.
• No tracking. The app contains no analytics SDKs, no advertising SDKs, and no third-party trackers of any kind.
• No cloud. Your books, highlights, notes, reading positions, and reading statistics are stored only on your device, in plain files you can inspect.
• No network requests. The app does not phone home. It works fully offline.

What stays on your device

• Imported EPUB files (stored in the app's Documents folder, included in your own iCloud/iTunes device backup if you have backups enabled — that backup is managed by Apple under your Apple account, not by us)
• Highlights and notes (a local JSON file, exportable as Markdown at any time)
• Reading positions and appearance settings
• Reading statistics (local sessions history)

Deleting the app deletes all of this. We could not recover it even if you asked us to, because we never had it.

Third parties

Leafmark uses the open-source Readium Swift Toolkit to render EPUB files. It runs entirely on your device and sends nothing anywhere.

Changes

If a future feature ever needs to touch the network (for example, optional iCloud sync), it will be opt-in, documented here first, and the default will remain: everything stays on your device.
