winnower collects nothing.

winnower has no server, no account and no analytics, and it never sends anything about you or your browsing. Its filter lists come inside winnower, so blocking never needs the internet.

winnower comes from the Chrome Web Store, and Chrome keeps it up to date. Google's privacy policy covers the store.

Copies installed from the zip download winnower used to offer ask GitHub once a day which version is the latest. That request carries no account, no identifier and nothing about you or the pages you visit.

The sites where you've switched blocking off, whether winnower is on, and which filter lists are on. Chrome keeps these on your computer, and removing winnower deletes them.

winnower keeps a short record of errors so a broken site can be reported. Developer mode, which is off unless you turn it on, records everything it does instead, including which sites. Either way the record stays on your computer and is thrown away when you close your browser.

To block and hide ads on whatever site you visit, winnower needs access to every page. It uses that access only to block, to hide, and to show you in its menu what ran on the page you're looking at. What it sees stays in your browser.

This site has no analytics, ads or tracking scripts, and it stores nothing in your browser: no cookies, and no local storage. Its fonts come from the site itself, not a font service.

The site is hosted on Vercel. Like any host, Vercel receives the requests your browser makes, including your IP address, to deliver the pages. Vercel's privacy policy covers what it does with them.

Releases, the source code and bug reports all live on GitHub, and GitHub's privacy statement covers those.

If what winnower or this site stores or sends ever changes, this page is updated first.
