Overview

JormunEpub is a browser extension for reading EPUB files. We are committed to your privacy. This policy explains clearly what data is handled and how.

Data We Do Not Collect

JormunEpub does not collect, store, transmit, or share any personal data. Specifically:

• We never see your epub files or their contents
• We never track what you read, how long you read, or your reading habits
• We never collect your name, email, IP address, or any identifying information
• We never use analytics, telemetry, or crash reporting services
• We never sell or share data with third parties — because we have no data to share

Data Stored Locally On Your Device

Everything JormunEpub stores stays entirely on your own device:

• Your epub files — stored in your browser's local IndexedDB storage, never uploaded anywhere
• Reading position and progress — saved in your browser's localStorage so you can resume where you left off
• Display preferences — font size, theme, line spacing, and other settings saved locally

You can delete all of this at any time from the extension's library page, or by clearing your browser's local storage.
