FontXify — Privacy Policy

Last updated: 2 June 2026

FontXify is a browser extension that changes the fonts displayed on websites you visit. This policy explains exactly what data the extension handles.

What the extension stores (on your device)

FontXify saves the following using Chrome's built-in extension storage:

• Your font rules and preferences (which font to apply globally, per-domain, and per-site, plus weight/spacing/line-height/size settings) and your list of favorite fonts. These are stored in chrome.storage.sync, which Chrome may sync across your own signed-in devices via your Google account. They are never sent to the developer.
• A cache of downloaded fonts and the Google Fonts catalog, stored in chrome.storage.local on your device to avoid re-downloading. This never leaves your device.

You can clear all of this at any time by removing the extension.

Data sent to third parties (Google Fonts)

When you apply a Google font, the extension requests that font from Google's public Google Fonts service:

• https://fonts.googleapis.com and https://fonts.gstatic.com — to download the font's stylesheet and font files.
• https://fonts.google.com/metadata/fonts — to download the list of available font families.

These requests include the requested font name and standard request metadata (such as your IP address), which Google receives as the service provider. This is the same data any website using Google Fonts would send. FontXify sends no other information, and sends nothing about the pages you visit. Google's handling of this data is governed by Google's Privacy Policy.

Website content

FontXify applies fonts by injecting a stylesheet into the pages you visit. It does not read, collect, store, or transmit the content of the pages you visit. The host permission is used solely to apply your chosen font styling.

Permissions and why they are used

• storage / unlimitedStorage — to save your settings and cache fonts on your device.
• scripting — to inject the stylesheet that applies your chosen font.
• activeTab — to read the current tab's address when you open the popup, so FontXify knows which site you are configuring.
• Access to Google Fonts (fonts.googleapis.com, fonts.gstatic.com, fonts.google.com) — used only to download the font catalog and the fonts you choose. It is not used to read the websites you visit.
• Access to the sites you visit (requested per site) — FontXify holds no access to your browsing by default. When you turn a font on for a site, a domain, or everywhere, Chrome asks you to grant access to just those sites. FontXify can only read or style sites you have explicitly enabled, and that access is removed when you turn a site off. No page content is read or collected.

Children's privacy

FontXify does not knowingly collect any data from anyone, including children.
