Is BlockDistraction – Block Site Extension safe?

Low risk

BlockDistraction - Block Site Extension sets an uninstall URL with encoded usage and subscription details.

The extension reads sync storage values for legacy status, installation date, Pro subscription status, manifest version, and rule count, then encodes them in the ctx parameter for https://blockdistraction.com/uninstall.html. Its service worker refreshes that uninstall URL shortly after startup and then on a daily alarm, so those fields are included if the browser opens the uninstall page.
