Privacy Policy — Reply Filter for X

Last updated: 2026-09-19

Reply Filter for X is a browser extension that collapses low-value replies on x.com post pages. This page explains exactly what data it handles.

What the extension sends

• The text and author handle of the post you are viewing, and the text and author handles of the replies being evaluated.
• Up to 10 "don't want to see" and 10 "keep" example replies that you explicitly marked.
• A random anonymous install ID generated on your device, used only for rate limiting.

It never reads or sends your X account, cookies, passwords, direct messages, browsing history, or any page other than x.com / twitter.com post pages.

Where it goes

• Free mode (default): to this service (xrf.ship2market.ai, a Cloudflare Worker), which forwards it to OpenRouter's TypeSafe Jev decision model and returns the scores.
• Your own key mode: directly from your browser to OpenRouter. This service is not involved.

What this service stores

• Only counters: replies evaluated today per install ID, per hashed IP address, and total daily spend. They expire after 26 hours.
• It does not store post text, reply text, examples, or raw IP addresses.

What stays on your device

Your examples, cached verdicts, review queue, custom keywords, blocked handles and optional API key are stored in Chrome extension storage. You can delete them from the options page or by removing the extension.

Sharing and selling

Data is not sold, not used for advertising, and not used for any purpose other than deciding which replies to collapse. Third-party processors: Cloudflare (hosting) and OpenRouter / TypeSafe (model inference).
