StopSlop runs inside your signed-in X session. Here is what it needs, what stays in your browser, and what leaves it.
What stays in your browser
Topic labels, the posts you hid or reopened, repeat counts, your topic choices and your reading persona are kept in a database inside your Chrome profile. Nothing syncs to an account. Removing the extension removes all of it.
What it needs, and why
- Your X timeline. To read the posts on the page, label them and fold the ones you chose not to read.
- Which X account is signed in. So labeling only ever runs for the account you confirmed in the guide. It never reads your password or your session.
- The side panel and local storage. That is where its controls and your choices live.
- A background worker. For the local database.
Nothing else. No browsing history, no other sites.
What leaves the browser
After you confirm your account in the guide, post text and author handles are sent to our labeling service so each post can get a topic. The persona sends post text too, when you use it. Your password, cookies and session never leave the browser. Labels are cached, so a post is sent once.
Usage statistics
To know whether StopSlop is installed and still used, it sends a few anonymous counts under a random id: installed, set up, and how many posts it folded today. No handle, no post, no choices. The counts stay on our own servers; no third-party analytics service is involved. The switch Share anonymous usage statistics in the side panel turns it off.
Nothing acts for you
No automatic liking, posting, following, reposting or messaging. The only button that touches X is "Not interested", and it waits for you to press it.
