Is BookmarkMars Assistant safe?

Medium risk

书签地球助手 sends visited page URLs and titles to its statistics endpoint when record-visit mode is enabled.

The extension's all-sites content script reports the current URL, page title, and referrer to its background worker on page load. If the synced record-visit setting is enabled, the worker queues a view event with the URL, title, visit time, user ID, favicon, and browser name, then posts the queue to the vendor statistics endpoint.
