Bot & Spam Blocker for Reddit does not collect, store or transmit any personal data to the developer or any third party.

What the add-on does:
• Reads the Reddit pages you visit to find the usernames of posters and commenters.
• Requests those users' public Reddit profile pages from reddit.com to read their contribution count and account age. These requests go only to Reddit, from your browser, like any normal page visit.
• Saves your settings, whitelists and cached profile stats (username, contribution count, account creation date, karma) in your browser's local extension storage. Cached stats expire after 7 days by default. Nothing is synced or uploaded.

There are no analytics, tracking, advertising or external servers. Uninstalling the add-on removes all of its stored data.
