Applies to the declutter browser extension for Chrome, Edge, Firefox and Safari. Last updated 3 October 2026.
declutter collects nothing on its own. It has no account, no analytics and no tracking. The one exception is a report you choose to send: see below.
Your settings, the sites you set to accept or leave alone, counters (banners answered, clicks saved) and the list of sites you reported as "not handled right" are kept in the browser's extension storage on your device. They are not sent anywhere unless you send a report. Removing the extension deletes them.
To answer cookie banners, declutter runs on the pages you open and looks for consent banners, then clicks through them (or calls the banner's own API) according to your choice. To hide YouTube Shorts it runs on youtube.com. It does not record, store or transmit the pages you visit or their contents. For the toolbar menu, the status of each open tab (site name, what happened to its banner) is kept in session storage, which the browser clears when it closes. Site names are saved only when you choose a per-site setting or press "report".
declutter makes no requests of its own, except fetching rule lists (JSON files). Versions from the stores fetch declutter's own list from theanhgen.github.io (GitHub Pages) every 12 hours, so fixes for sites arrive without an update; you can remove it in settings → rule lists, and add others. Those requests carry no information about you beyond what any download does (your IP address is visible to that server; GitHub keeps its own logs).
If you switch on "send Global Privacy Control" (off by default), your browser adds the standard
Sec-GPC: 1 header to its requests and tells pages navigator.globalPrivacyControl, asking
sites not to sell or share your data. It is not sent to sites you set to accept or leave alone. declutter learns
nothing from it.
When you remove declutter from Chrome, Edge or Firefox, the browser opens a page on theanhgen.github.io with links for reporting what went wrong. That page has no script and records nothing.
After you press "not handled right", the menu offers "send to developer" and shows what it sends. Only if you press it, declutter sends: the site's address only (for example https://www.idnes.cz, never the page's path, query or fragment), what declutter saw on that page (for example "failed" and the banner's platform name), the declutter version and the browser type. No account, identifier, cookies, page content or other browsing is included. Reports are stored in a database hosted by Supabase (EU, Frankfurt) that only the developer can read, and are used only to fix how declutter handles those sites. Like any web request, it reveals your IP address to Supabase's servers, which keep request logs briefly; declutter does not store it. To have a report deleted, open an issue or email via the link below.
Supabase stores reports you choose to send, and nothing else. GitHub Pages serves the rule list and the pages above. declutter includes DuckDuckGo's open-source autoconsent library, which runs locally and sends nothing.
