Description
Privacy organized by purpose. Block ads, trackers and banners per site. Two modes, conditional GPC, 40+ blocklists, open source. ProtoConsent is a browser extension that gives you purpose-based control over how websites may use your data - directly from your browser, with no central server. You set a privacy profile (Strict, Balanced, or Permissive) and adjust six purpose toggles: functional, analytics, ads, personalisation, third-party services, and advanced tracking. ProtoConsent enforces your choices at the network level, blocking requests before they leave the browser. KEY FEATURES • Per-site profiles and purpose toggles - choose a default privacy profile (Strict, Balanced, Permissive) that applies everywhere, then override per site with six individual purpose toggles: functional, analytics, ads, personalisation, third-party services, and advanced tracking. • Two operating modes - Blocking mode enforces your choices directly using 100,000+ curated domains organised by purpose. Monitoring mode runs on top of your existing ad blocker and shows what each tool does, per purpose, in the Overview dashboard. • Enhanced protection out of the box - 40 curated blocklists from trusted open-source projects in three tiers (basic, full, optional), cosmetic filtering, CNAME detection, URL parameter stripping, and regional filters for 36 languages. Lists refresh automatically. • Consent banner management - banners from known CMP frameworks (including IAB TCF v2.2) are handled automatically based on your purposes. Cosmetic hiding, scroll unlock, and experimental cookie injection. No click simulation. • Overview dashboard - real-time view with purpose-attributed block counts, signal indicators (GPC, Client Hints, CMP, site declarations), coverage metrics, and parameter stripping detail. • Privacy signals - conditional GPC header per site (not a global toggle), Client Hints stripping to reduce fingerprinting, and URL parameter stripping (utm_source, fbclid, etc.). • Site declarations - websites can publish a .well-known/protoconsent.json to declare their data practices. Displayed in a side panel with Consent Commons icons. • Inter-extension API - other privacy extensions can query your consent state. Disabled by default, read-only, per-extension allowlist. • Local-only and open source - no account, no cloud, no backend. Extension GPL-3.0+, SDK MIT, docs CC BY-SA 4.0. WHAT IT IS NOT ProtoConsent is not a VPN or anonymity tool. It is a personal consent control panel in the browser, organised around purposes. It can coexist with existing ad blockers and consent tools. Learn more: https://protoconsent.org Live demo: https://demo.protoconsent.org Source code: https://github.com/ProtoConsent/ProtoConsent
