Privacy Policy for Medium to Kindle EPUB

Effective date: April 12, 2026

Medium to Kindle EPUB is a local-first Chrome extension that converts a Medium article currently open in your browser into an EPUB file.

Data collection

This extension does not collect, sell, or share personal information.

• No analytics or tracking SDKs are used.
• No user account is required.
• No browsing history is collected beyond the currently active Medium tab when you click the extension.

How data is used

When you click Create EPUB, the extension:

1. Reads article content from the active Medium tab.
2. Optionally fetches article image files referenced by that page so they can be embedded in the EPUB.
3. Generates the EPUB in-browser and saves it to your device using Chrome's Downloads API.

All processing is performed locally in your browser session.

Data storage and retention

• The extension does not transmit extracted article content to an external server controlled by us.
• The extension does not store personal data in remote databases.
• The generated EPUB file is saved only where you choose on your device.

Permissions and why they are needed

• activeTab: access the tab you chose so article content can be extracted.
• scripting: run extraction logic in that page context.
• downloads: save the generated EPUB file.
• Host permissions for https://medium.com/* and https://*.medium.com/*: limit operation to Medium pages.

Third-party services

The extension does not load remote executable code. Network requests are limited to fetching content/assets from Medium pages needed to build the EPUB.

Children's privacy

This extension is not directed to children under 13 and does not knowingly collect personal information from children.

Changes to this policy

If this policy changes, the updated version will be published in this repository with a revised effective date.
