Markwise is a local-first browser extension. It stores bookmark metadata such as title, URL, domain, summary, tags, folder, saved date, and local search data on the user device. Markwise reads the current tab URL and title when the user opens the popup, reads the browser bookmark tree to save and check duplicates, and may read selected text or page text only when the user saves a page or requests metadata generation. Markwise does not collect, sell, or share personal data with the developer, and it does not send bookmark data to a Markwise server. Optional external AI requests only happen if the user configures and uses a third-party or self-hosted AI provider; those requests are governed by the selected provider. Users can delete data by removing saved entries or uninstalling the extension. Public policy: https://ai-bookmark.ming13821007683.workers.dev/privacy
