Cookie & Local Storage Policy

Effective Date: September 21, 2026 | Last Updated: September 21, 2026

Learn how browser local storage, WebAssembly caching, and third-party advertising cookies function on our site.

1. Local Storage & WASM Binary Caching

To deliver high performance and near-instant processing, Free Browser Tools utilizes browser Web Storage (IndexedDB, Cache API, and localStorage):

WASM Model Caching: Pre-compiled WebAssembly binaries (e.g., Tesseract.js language data, OpenCV.js, and ONNX AI models) are cached in your browser so you don't have to re-download them on subsequent visits.
User Theme Preferences: We save your preferred UI theme (Dark/Light mode) in localStorage.

2. Analytics Cookies

We use Google Analytics (gtag.js) cookies to monitor general traffic performance and page load metrics. These cookies collect aggregated data without tracking individual identities.

3. Advertising Cookies

Advertisements are served via Google Ad Manager (GAM). Google and its advertising partners use cookies to serve ads based on prior visits to our website or other websites on the internet. You can manage or disable ad personalization settings through your Google account or browser preferences.

4. Managing Cookies

You can choose to block or remove cookies through your web browser settings. Note that disabling WASM local caching may increase initial load times when using heavy processing tools.
