Data Collection

We are committed to protecting your privacy. Here's what data we collect:

Bookmark titles, URLs, folder structure, creation dates, and Chrome sync status from the current Chrome profile
Optional browser history matches only after you grant the history permission while starting an analysis
When you start a link check, the HTTP status, final destination URL, and at most a one-byte response sample from each selected destination
Link-check results, language preference, and a local Mac App connection token stored in Chrome local extension storage
No account registration, advertising identifier, analytics telemetry, or developer-server upload is required

The data we collect is used to:

Generate the bookmark analysis report and the categories you explicitly open
Estimate recent visible visits when you choose to grant Chrome history access
Carry out bookmark sorting, moving, URL cleanup, and deletion only after your explicit action
Remember completed link checks and your interface language on this device

We take the security of your data seriously:

Bookmark and history analysis runs locally in the extension and is not uploaded to our servers
The optional Mac App connection uses only 127.0.0.1 on the same computer and verifies the official extension ID
Link checks omit credentials and referrers, prefer HEAD, and use a one-byte Range GET only when a site does not support HEAD
The extension does not download or execute remotely hosted code
Use of information received from Chrome APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements

Information about how we share your data:

We do not sell bookmark, history, or link-check data and do not share it with advertisers or data brokers
When you start a link check, the extension contacts the selected bookmarked website directly; that website may receive the normal network information needed to answer the request
No developer-operated server receives bookmark titles, URLs, history matches, or analysis results

How long we keep your data:

Bookmarks and history remain managed by Chrome and are not copied to a developer-operated server
Link-check results and preferences remain in Chrome local extension storage until you clear them or uninstall the extension
Bookmark changes are applied through Chrome APIs and may sync to other devices when Chrome Sync is enabled

You have the following rights regarding your data:

Deny or revoke the optional history and website permissions in Chrome at any time
Clear local extension data or uninstall Chromate to remove saved link-check results and preferences
Review every proposed move, edit, or deletion before it changes your bookmarks
