1. Summary
Efrd does not read, store, or transmit the content of the sites you visit. It NEVER collects or transmits the sites you visit, URLs, or your browsing history. Your settings are stored only in your browser via chrome.storage.sync (browser.storage.sync on Firefox) — they never go to a server we own. Anonymous usage statistics are fully opt-in and disabled by default.
2. Permissions the extension requests and why
storage — To save your preferences: font, weight, color, background, sound.
scripting — A fallback mechanism to apply settings instantly right after the extension is installed or updated.
activeTab — Required so the fallback mechanism above can only operate on the tab that's currently open.
host_permissions (<all_urls>) — Required so bionic reading, font, and theme features can run automatically on every site you visit. It lets us change how a page looks; it is never used to read, store, or transmit page content.
3. What data is NOT collected
The sites/URLs you visit, page content, form data, passwords/session information, location, or any information that directly identifies you (name, email, etc.) — none of this is collected or transmitted.
4. Optional (opt-in) anonymous usage statistics
The "Privacy" section of the settings panel has a toggle that is off by default. If you enable it, only aggregate, site-independent counters (such as "bionic reading enabled X times") are sent in bulk. No information about which site or when you used a feature is ever sent. You can turn this off at any time from the same panel.
5. Third-party services
To display fonts (Lexend, Atkinson Hyperlegible Next, Inter), font files are downloaded from Google Fonts (fonts.googleapis.com, fonts.gstatic.com). As a natural consequence of this standard web request, your browser's IP address reaches Google — this is an inherent part of how Google Fonts works and is not otherwise processed by us. Google's privacy policy: https://policies.google.com/privacy
6. Sale or sharing of data
No user data is sold, rented, or shared with third parties for marketing purposes.
7. Data retention and deletion
Your settings are automatically deleted by the browser when you uninstall the extension. If you enabled usage-statistics counters, you can reset them via the "Reset" button in the settings panel or by uninstalling the extension.
8. Children's privacy
Efrd does not knowingly collect data from children under 13. Since the extension does not collect any personal data in the first place, it poses no additional risk in this regard.
9. Changes to this policy
If this policy is updated, the "Last updated" date on this page will change accordingly.
