Leafmark — Privacy Policy

Last updated: October 5, 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

Books, highlights, notes and reading habits stay on your device or in your own iCloud. Purchase processing in versions that enable RevenueCat is described below.

• No account. You never sign up, log in, or give us an email address.
• No reading-behavior tracking or advertising. Purchase analytics use RevenueCat only in versions that enable it.
• No Leafmark cloud. Leafmark has no server. Your books, highlights, notes, reading positions, and reading statistics are stored on your device, in plain files you can inspect. Some of them are also synced through your own iCloud (see iCloud sync below).
• No reading content is sent to us. Core reading features work offline. Apple and, in enabled versions, RevenueCat handle purchase-service requests.

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 from your device. Copies already synced to iCloud stay in your iCloud account. We could not recover any of it even if you asked us to, because we never had it.

iCloud sync

• When you are signed in to iCloud with iCloud Drive turned on, Leafmark automatically copies your highlights (with their text and notes), bookmarks, reading positions, and the title and author of each book in your library to the app's folder in your iCloud Drive, so your other devices can pick them up.
• There is no switch for this in the app. Signing out of iCloud or turning off iCloud Drive stops it, and the app keeps working on its own.
• EPUB files, reading statistics, imported fonts, and appearance settings are not synced.
• The transfer is done by iOS, and the data is stored in your iCloud account. None of it is sent to us.

Third parties

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

Purchase processing with RevenueCat

Versions that enable RevenueCat use its purchase service for receipt validation, fraud prevention, purchase reliability, and purchase analytics. The currently distributed versions keep this SDK disabled and do not send data to RevenueCat.

When enabled, the SDK automatically sends past and new Apple purchase records, including product and transaction identifiers, purchase dates and status, and renewal, expiry or revocation information where applicable. It also uses a randomly generated anonymous app user ID. RevenueCat receives request information such as app and operating-system versions, locale, currency and network IP address. Purchase records may include purchases from earlier versions and both production and Sandbox transactions.

The app does not add your name, email address, advertising identifiers or a custom cross-app identity to RevenueCat. Automatic device-identifier collection is disabled. App-created content is not sent to RevenueCat. See RevenueCat's Privacy Policy.

Apple StoreKit continues to determine purchase ownership and eligible Family Sharing access. Existing purchases, prices and free features are unchanged, and this migration does not require a repeat purchase. Uninstalling the app removes local app data but does not delete Apple's purchase history or RevenueCat purchase records. Manage subscriptions through Apple and send privacy or deletion requests privately to andphoto.co@gmail.com. Do not post receipts or transaction identifiers in public issues.

Changes

This policy describes the automatic purchase-service processing in versions that enable RevenueCat. Other future changes will be documented here before activation.
