Privacy Policy
Last updated: July 17, 2026. BrowserPowerToys is built around a single, absolute principle: your data belongs on your device.
1. The Zero-Upload Guarantee
Unlike traditional online utilities that require uploading your documents, images, audio, or video files to a remote server, BrowserPowerToys processes everything locally in your web browser.
We use modern browser technologies such as WebAssembly (WASM), Web Workers, and client-side JavaScript APIs to perform conversions, compression, editing, and formatting directly inside your browser sandbox. Absolutely zero bytes of your files are uploaded to our servers or any third-party services.
2. Data We Do Not Collect
Because all processing happens on your local machine, we have no access to, nor do we collect, view, or store:
- Any files you drag and drop, select, or input into our tools.
- Any passwords, keys, or decrypted data you generate using our security or developer tools.
- Any text data, code inputs, formats, or parameters you submit to our formatting or text tools.
3. Local Storage and Preferences
We may store simple preferences on your device (such as your dark/light theme preference or tool-specific settings) using standard browser APIs like localStorage or sessionStorage. This data remains entirely on your device and is never sent to our servers. You can clear this data at any time by clearing your browser cache and cookies.
4. Basic Web Analytics
To understand website traffic and improve user experience, we use Google Analytics 4 and Cloudflare Web Analytics. These services record usage data such as page views, referrer URLs, scrolling, approximate location, and browser or device type, and Google Analytics may set cookies or similar identifiers to do so. This telemetry never includes any file names, file contents, inputs, or generated outputs. You can see these analytics requests in your browser's DevTools; they are separate from your files, which stay on your device.
5. Independent Verification: How to Verify Zero Uploads
You do not have to rely solely on our word. You can independently verify our zero-upload, client-side architecture using standard browser tools or an air-gap test:
- The DevTools Payload Check: Press F12 (or right-click → Inspect) to open your browser's Developer Tools and switch to the Network tab. Filter by Fetch/XHR. Select and process any document, image, or text input. You will observe that 0 bytes of your files or input data are ever transmitted over the network. Analytics requests may appear; they carry page activity only. File processing is executed 100% in local browser memory via WebAssembly and Web Workers.
- The True Air-Gap / Offline Test: Load any tool on BrowserPowerToys, then completely disconnect your internet connection (turn off Wi-Fi or unplug your Ethernet cable). Continue processing your files, converting images, or formatting data. Every tool functions seamlessly offline because the execution code runs entirely on your local machine. An offline browser physically cannot send your data to any server.
6. Third-Party Websites
Our website may contain links to external sites that are not operated by us. Please be aware that we have no control over the content and practices of these sites, and cannot accept responsibility or liability for their respective privacy policies.
