Privacy Policy

Effective date: October 13, 2026

Leafpost is a Chrome extension that turns web pages into e-books and sends them to your Kindle. It was built so that your reading stays private: we do not run servers that receive your content, we do not collect analytics, and we do not sell or share any data.

What happens when you send a page

1. When you click Leafpost (or use its menu or shortcut), the extension reads the current page, the text you selected, or the link you chose. This happens only on your request.
2. The page is converted into an EPUB file inside your browser. If you allowed it, images in the article are downloaded from the websites that host them so they can be included in the book.
3. The file is uploaded from your browser directly to Amazon's Send to Kindle service using the Amazon account you are signed in with in Chrome. Amazon's privacy notice applies to that delivery.

Data stored on your device

• Settings (your Amazon store, whether to include images, PDF layout) are saved with Chrome's storage and, if you use Chrome sync, synced between your own browsers.
• A history of your last 100 sends (title, page address, date and whether it succeeded) is kept locally so you can see it in the settings page. It never leaves your device.

Removing the extension deletes this data.

Data we collect

None. Leafpost has no user accounts, no tracking, no advertising and no analytics. The developer cannot see what you send, your Amazon account, or your browsing.

Permissions

• Active tab and scripting: to read the page you choose to send, only when you ask.
• Amazon sites: to upload your file to Amazon's Send to Kindle service with your session.
• Access to all sites (optional): only if you enable it, to download article images and PDFs or pages you send from a link.
• Storage, context menus, offscreen document: to save settings, add the right-click menu, and build the e-book in the background.

Children

Leafpost is a general-purpose tool and does not knowingly collect information from anyone, including children.

Changes

If this policy changes, the new version will be published on this page with a new effective date.

Política de privacidad (resumen en español)

Leafpost no recoge datos personales: no tiene servidores que reciban tu contenido, ni cuentas, ni analítica. Cuando envías una página, se convierte en libro dentro de tu navegador y se sube directamente al servicio Send to Kindle de Amazon con tu propia sesión. Tus ajustes y el historial de los últimos 100 envíos se guardan solo en tu dispositivo y se borran al desinstalar la extensión.

Leafpost is not affiliated with Amazon. Kindle is a trademark of Amazon.com, Inc. or its affiliates.
