Privacy Policy
Last updated — March 1, 2026
SlopMuter is built with a simple privacy principle: your data never leaves your device. We don't collect, store, or transmit any personal information. Period.
What we don't collect
- No personal data or account information
- No browsing history or feed content
- No analytics, telemetry, or usage tracking
- No cookies or fingerprinting
- No data is sold, shared, or transmitted to third parties
What is stored locally
SlopMuter uses your browser's local storage to save:
- Your blocklist preferences (which lists you've enabled or disabled)
- Cached blocklist data (so the extension doesn't re-download unchanged lists)
- Scan and removal statistics (displayed in the extension popup)
All of this data lives entirely in your browser and is never transmitted anywhere.
Network requests
The only network requests SlopMuter makes are to fetch publicly available blocklist files hosted on GitHub. These requests contain no user-identifying information — they are simple GET requests to public URLs.
SHA-256 hashing is used to check whether a blocklist has changed before re-downloading, minimizing unnecessary network activity.
Browser permissions
SlopMuter requests only the permissions it needs:
- storage — to save your preferences and cached blocklist data locally
- activeTab — to communicate with the current X/Twitter tab and filter posts
The extension only runs on X/Twitter pages. It does not inject code into other websites, run in the background on unrelated pages, or access any data beyond what is needed to filter your feed.
No account interaction
SlopMuter does not block, report, mute, or interact with any account on X/Twitter. It only hides posts locally in your browser. Your X account settings are never modified.
Open source
SlopMuter is fully open source. You can audit the extension code, the blocklists, and the blocklist criteria at any time on GitHub.
