Feedmark privacy policy

Effective 2 July 2026.

Feedmark is an RSS reader that runs entirely in your browser. It has no server, no accounts, no analytics, and no way to phone home. This page exists because the extension stores require one — and it's short enough to actually read.

What Feedmark stores

Everything Feedmark knows lives in your browser's local extension storage:

• the titles and URLs of bookmarks in the one folder you point it at,
• any feed address you paste in yourself,
• item titles and identifiers from those feeds, used to count what you haven't read,
• standard caching headers (ETag, Last-Modified), so feeds aren't re-downloaded needlessly.

Nothing syncs anywhere. Uninstalling the extension deletes all of it. I have no copy — there is nowhere for a copy to go.

What Feedmark sends, and to whom

Feedmark fetches the feeds you subscribed to, directly from your browser to the sites that publish them, over https only. Those sites see what they'd see if you visited them yourself: your IP address and the request. That is the complete list of network traffic. There is no other destination — no proxy, no aggregator, no telemetry endpoint, and nothing that reaches me, the developer.

What Feedmark doesn't do

• It doesn't read your browsing. There are no content scripts; it never sees the pages you visit, only the specific feed URLs you gave it via a bookmark or a paste.
• It doesn't touch bookmarks outside the folder you chose, and it never edits any.
• It doesn't collect analytics, show ads, or share or sell anything — there's nothing to sell.

Changes and contact

If any of the above ever changes, this page and the extension's store listings change with it, and the version history of this page is public in the Feedmark repository. Questions or concerns: open an issue there, or email json.birchall@gmail.com.
