Your privacy is our priority. Every note, highlight, and piece of analytical data is stored 100% locally on your computer's browser storage. We do not use cloud servers, meaning your data never leaves your device.

Yes, Web Notes is completely free and designed to be a high-performance productivity tool for everyone. There are no hidden subscriptions or data-selling practices involved in its operation.

You can easily backup your entire library by visiting the Settings page and clicking the "Export to Excel" button. This generates a high-fidelity XLSX file containing all your notes, timestamps, and source URLs for safe archival.

Absolutely. Web Notes is designed to work across the entire web. You can use the floating on-page canvas or the right-click "Add Web Note" context menu on virtually any public website to capture information instantly.

Because all data is stored locally in your browser, uninstalling the extension will remove all captured notes from your device. We highly recommend using the Export to Excel feature in Settings to save a backup before uninstalling.

Not at all. Web Notes is built with a "Light-Performance" architecture. It only activates its on-page components when you explicitly choose to take a note, ensuring your browsing speed remains lightning-fast even with a large library of discoveries.
