  description

  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
  
  • Two operating modes - Blocking mode blocks requests directly using 40,000+ 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.
  
  • Overview tab - real-time dashboard with purpose-attributed block counts, signal indicators (GPC, Client Hints, CMP, site declarations), coverage metrics, and parameter stripping activity.
  
  • Consent banner auto-response - banners from 31 CMP frameworks (including IAB TCF v2.2) are answered automatically based on your purposes, plus site-specific signatures. No click simulation.
  
  • Protection lists - 26 curated blocklists from trusted open-source projects. Three presets or individual list control. Lists can auto-activate based on your denied purposes.
  
  • Regional filter lists - language-specific blocking and cosmetic filters, auto-detected from your browser language.
  
  • 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.).
  
  • Log monitoring - real-time view of blocked requests, GPC signals, blocked domains by purpose, CNAME cloaking indicators, and domain whitelist management.
  
  • 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 DOES NOT DO
  
  ProtoConsent is not a full ad blocker and not a VPN. It adds a missing layer: a personal consent control panel in the browser, organised around purposes.

  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.
