Nestmark Privacy Policy

Effective date: 25 September 2026 · Applies to: Nestmark 1.4 and later

Nestmark is a browser extension for highlighting text on web pages. This policy explains what the extension does with your data. The short version: Nestmark keeps everything on your device. It collects nothing and sends nothing anywhere.

What Nestmark stores

When you highlight text, Nestmark saves the following locally in your browser's extension storage (chrome.storage.local / browser.storage.local):

This data never leaves your device unless you choose to export it.

Notes are private to you. Nestmark never writes a note into the web page or sends it to the page, so the websites you visit cannot read what you wrote about them.
