Privacy Policy

Nothing leaves your device.

Effective date: 2026-07-06  ·  Applies to: the Nullfeed browser extension

Nullfeed is local-only by design. No accounts, no analytics, no telemetry, no tracking of any kind. This policy describes exactly what the extension does — nothing is simplified away.

What Nullfeed stores, and where

All of your data lives in your browser's local extension storage on your device:

  • your blocking rules (built-in toggles and elements you chose to block),
  • per-site settings and presets,
  • the self-lock timer state,
  • a cached copy of the current blocking-rule list.

None of this is transmitted to us or anyone else. Uninstalling the extension deletes it. The export feature writes this data to a file on your device that only you control.

The only two network requests Nullfeed ever makes

REQUEST 01 · AUTOMATIC · READ-ONLY

Blocking-rule updates

Roughly every 6 hours, and on browser startup, the extension downloads the current blocking-rule list from our server (a Cloudflare Worker). This is a plain download: no account, no identifier, no cookies, and no information about you or your browsing is included. Like any web request, our infrastructure provider (Cloudflare) processes your IP address to deliver the response; we do not log or store it.

REQUEST 02 · ONLY WHEN YOU CLICK IT

“Report broken site”

If — and only if — you explicitly choose right-click → “Report broken site” and press Send, the extension transmits: the site name (e.g. “youtube”), the CSS selectors of elements you blocked on that site, your optional typed note, and the extension/rule-list version numbers. The dialog shows you this exact list before you send. Reports contain no personal data and no page content; they are stored for up to 90 days for review and then deleted. Your IP address is used only in a transient rate-limiting counter that expires within one hour and is never stored with a report.

That is the complete list. Nullfeed never sends page content, browsing history, or any behavioural data anywhere.

What Nullfeed does on pages

On the seven built-in sites (YouTube, X/Twitter, Reddit, LinkedIn, Facebook, Instagram, Amazon) — and on any additional site you explicitly enable via “Enable on this site” or the right-click menu — the extension reads the page's structure locally in your browser to hide feed, Shorts/Reels, sponsored, and user-chosen elements. This processing never leaves your device.

Access to additional sites is granted by you per site through Chrome's own permission prompt, and you can revoke it at any time from the extension's details page.

Third-party links

The extension links to Ko-fi (donations) and niallcodes.com (our other tools). These open in a new tab and have their own privacy policies; nothing is sent to them by the extension itself.

Data sales and sharing

We do not sell, share, or monetise any data. There is nothing to sell.

Who we are

Nullfeed is published by Florence Publishing Ltd (United Kingdom), trading as niallcodes.

Changes

Any change to this policy will be listed in the extension's open changelog and reflected in the effective date above.
