Sublore has no accounts, analytics, telemetry, or ads. Its developer receives no data from it.

What leaves your browser. When you click Check beside a Reddit commenter, Sublore sends that commenter's username and a date range to the Arctic Shift API at arctic-shift.photon-reddit.com (https://github.com/ArthurHeitmann/arctic_shift). On a subreddit thread, it may send one more request for the same username with a 7-day range. Requests carry no cookies, page URL, page content, or watchlist. Arctic Shift receives your IP address, as with any web request. Nothing is sent until you allow lookups in settings, and then only when you click Check, Retry, or the recheck button beside a commenter.

What stays in your browser. Sublore stores your settings and up to 500 cached lookups (each checked username with its subreddit names and counts) in the browser's extension storage. Clear cache in settings deletes the cache. Removing the extension deletes everything.

Sublore uses this data only to show subreddit activity beside commenters. It does not sell the data, transfer it anywhere except Arctic Shift for the lookup, or use it for advertising.
