Privacy
For the Clicksaur browser extension and clicksaur.com. Last changed 26 October 2026.
Clicksaur keeps what you mark in your browser. It has no account and no server of its own. Nothing is sent anywhere unless you switch on an online feature, and Firefox asks you to confirm before it turns on.
What Clicksaur keeps, and where
Your highlights, notes, flags, clippings, notebook and settings are kept in the storage your browser gives each
extension (storage.local), on your computer. They aren't synced or sent anywhere. Removing the
extension removes them. To move them to another computer, use the notebook's backup, a file that you save and
keep.
Pictures the magnifier and the Developer tools take of a tab are made in your browser and stay there.
What it collects
Nothing by default. When you install Clicksaur, Firefox lists its required data collection as none, and two optional kinds: website content and browsing activity. They belong to two switches in Settings → Online. Both start off, and Firefox asks you to confirm before either turns on. Turning a switch off withdraws the permission.
| Switch | What is sent, and to whom | Firefox's name for it |
|---|---|---|
| Look things up online | Define: the word you chose goes to Wiktionary, and to Datamuse if Wiktionary has no entry. Find synonyms: the word goes to Datamuse. Translate: opens Google Translate with the text you selected. Translate page: opens Google Translate with the page's address. Google Lens: opens Google Lens with the address of the image you chose. | Website content, browsing activity |
| Save a public copy of pages I annotate | The address of a page you highlight or note on goes to the Internet Archive, which saves a public copy. Nothing else is sent. | Browsing activity |
Until a switch is on, those menu items say what they need and link to Settings. Those services handle what they receive under their own privacy policies.
Things you click that open another site
A few menu items take you to another site, the way a link does. Each one runs only when you click it, and its label names where it goes:
- Search and Try on hand your search to one of Firefox's own search engines, as Firefox's search bar would.
- On a map site, this spot on Google Maps, OpenStreetMap, Apple Maps or Bing Maps opens the same place on that map.
- Save the thumbnail on YouTube downloads the picture from YouTube's image server, as saving any image does.
- Copy image fetches the picture you right-clicked from the site that serves it, as your browser already did to show it.
- Open in new tab, Open image and similar items open the address you right-clicked.
What its permissions are for
| Permission | Used for |
|---|---|
| Access your data for all websites | Drawing Clicksaur's menu in place of the right-click menu on any page, and showing your highlights and notes there. The page is read in your browser and isn't sent anywhere. |
| Storage | Keeping your highlights, notes, notebook and settings. |
| Bookmarks | Bookmark this page and Bookmark link, when you choose them, and showing whether a page is already bookmarked. |
| Downloads | Save image as…, Save link as…, screenshots, Save the thumbnail and notebook exports, each with Firefox's Save dialog. |
| Notifications and alarms | The timer on the desk, and its notice when time is up. |
| Search | Searching with Firefox's own search engines. |
| Clipboard (write) | The Copy items. Pasting uses Firefox's own Paste prompt. |
| Scripting | Loading the reader's text extractor, Mozilla's Readability, packaged with the extension, and the styles for highlights. |
Clicksaur doesn't load code from the internet. Everything it runs comes with the extension.
This website
clicksaur.com has no analytics and sets no cookies. It remembers the theme you pick in your browser's local storage. The menu you can try on the home page keeps everything in memory and forgets it when you leave, except that Define and Synonyms there ask Wiktionary and Datamuse, as the extension does. The site is served by Cloudflare, which handles requests under its own policy.
Changes
If something Clicksaur sends changes, this page and the extension's Settings change with it before the new version is released, and nothing new is sent without asking you first.
