Consent you can express, enforce and observe
User-side, purpose-based consent for the web
Browser extension · Blocklists · Website
ProtoConsent organizes privacy around purposes instead of individual trackers or domains. The project has two main outputs: a browser extension for end users and purpose-based blocklists for any tool.
No central server, no tracking, no sharing of personal data.
A personal consent control panel that lives in the browser. Purpose-based blocking, tracker detection, and signal management in one place - can coexist with existing blockers and consent tools.
- Per-site profiles and purpose toggles: choose a default privacy profile that applies everywhere, then override per site and refine individual purposes across six data-use categories.
- Enhanced protection out of the box: curated blocklists, cosmetic filtering, CNAME detection, URL parameter stripping, and regional filters for 36 languages - enabled by default and kept up to date automatically.
- Two operating modes: Blocking enforces purpose-based blocking directly. Monitoring delegates to your existing blocker and adds purpose attribution and signal observability.
- Consent banner handling: cosmetic hiding, scroll unlock, and experimental cookie injection to auto-respond to consent banners based on your purpose preferences. No DOM interaction, no click simulation.
- Site declarations: websites can publish .well-known/protoconsent.json to declare their data practices. Open protocol with spec, JSON Schema (source), validator, and GitHub Action.
- JavaScript SDK (MIT) for web pages to query user preferences via protoconsent.get('analytics').
