The uuTools extension does not collect, sell or share any personal data. Your favorites, tasks, shortcuts and settings are stored only in your browser (extension storage). The extension downloads the public tool list from www.uutools.net. Files you choose are handed from the extension to the uutools.net tab in your own browser; the extension does not upload them anywhere. If you turn on sync, favorites, tasks, shortcuts, notes and settings are stored in your browser account's sync storage (Chrome or Firefox Sync). The weather widget sends the city you enter to open-meteo.com to show the forecast. If you choose "Photo of the day" as background, the photo is loaded from picsum.photos (Lorem Picsum, photos from Unsplash). A background image you upload stays in your browser. uutools.net's own privacy policy applies to its pages: https://www.uutools.net/en/privacy-policy
