Simplify EU websites.
End cookie banners.
ADPC is an open, machine-readable signal for privacy choices (consent, refusal, withdrawal and objection). A digital signal can replace thousands of annoying banners and make users’ privacy choices simple and interoperable across websites and devices.

From cookie banners to effortless privacy choices.
Today you are asked about the same privacy decisions again – and again. The current “cookie banner” approach is exhausting for users, and generates a lot of friction for organisations. It is not suitable for future interfaces, like immersive services and AI-mediated environments.
ADPC only changes the communication channel through which choices are communicated. Instead of interface requiring hundreds of manual clicks, ADPC enables a standardised digital exchange between the service and the user-side software that represents the person covering all relevant GDPR rights, like consent, refusal, withdrawal and objection.
Developed by economics and privacy researchers and aligned with the GDPR and ePrivacy Directive, ADPC is not a simple opt-out flag that is the same for all services. It is a richer communication mechanism for a European fundamental-rights approach allowing to have specific choices per controller and purpose.

Proven technology.
All privacy choices covered.
For decades our devices exchange user preferences automatically. For example, browsers send websites language preferences or screen sizes to ensure users get the right page in the right format.
ADPC uses these existing digital communication channels (like header signals) to also communicate privacy choices. This way users can automatically send their preference to services – without effort, annoyance or friction.
Each controller provides its privacy options
Each controller can provide a list of freely defined purposes for which it seeks to process user data. Controllers can choose from existing B2B purpose definitions or choose their own purposes. The user agent can load these lists with each visit.
Users make their privacy choices
Users can make privacy choices manually or through automated agents like learning browser plug-ins. If users do not want to consent to processing, they can simply stay silent or send a reject signal. Consent or objections are actively communicated by the user agent.
Effortless compliance
Organisations read the signal and apply user preferences without banners, annoyance or friction. Organisations benefit from a massively improved user experience, lower bounce rates and an increased legal certainty.
Built for Europe.
Open to the world.
ADPC was designed around the actual requirements of EU data-protection law, not as a workaround. At the same time ADPC uses open concepts like “opt-in” and “opt-out” that are interoperable with most global privacy frameworks.
GDPR & ePrivacy choices fully covered
ADPC starts from EU data-protection logic built around consent, refusal, withdrawal and objection. This allows ADPC to make “cookie banners” fully redundant.
Fair and open communication
Both services and user-side tools participate in the exchange. Services express what they request; user-side software communicates back. Neither party nor a third party has a gatekeeper function. Controllers keep the power to set purposes and have individual consent for their service.
Specific Purposes
ADPC can communicate specific choices for specific purposes. It is not a global binary system like DNT or GPC. Users keep different preferences for analytics, advertising, personalisation and more.
Opt-In Compatible
Unlike signals designed purely for opt-out markets, ADPC supports consent as well as refusal, withdrawal and objection matching the full grammar of EU data-protection law.
Implementation-Ready
ADPC is publicly specified and already connected to existing website and CMP workflows. There is a working browser extension, WordPress integration and documented CMP-side support.
Future-Ready
ADPC extends beyond websites to IoT, mixed reality, children’s protection with guardian support, AI-assisted privacy management and rights-aware AI-based systems.
ADPC works for people and for organisations.
Users are exhausted by “cookie banners”. Organisations are struggling with compliance that disrupts user flows. ADPC addresses both through a shared rights infrastructure. We have developed sample-implementations for users and organizations to show how simple implementing Article 88b can be.
