MyDataKey is a nonprofit data ownership tool that helps you discover, manage, and control your personal data. Using the PDAOS (Personal Data Asset Origination System), you can see who has your data, opt out of data brokers, and generate proof-of-ownership certificates for your personal information.

The core platform is free. MyDataKey is operated by Own Your Data Inc., a nonprofit organization. Our mission is empowering individuals to exercise their data privacy rights. The iOS app is free to download and uses 100% local storage — we never collect or store your personal data on our servers.

How does data opt-out work?

MyDataKey connects you to over 20 data broker opt-out portals and walks you through the removal process for each one. We provide direct links, pre-filled forms where possible, and tracking so you can monitor which brokers have processed your removal request.

What is a data certificate?

A data certificate is a verifiable document that proves you have taken steps to manage and protect your personal data. It includes a timestamp, the actions you have completed, and a unique verification code. Think of it like a deed for your house — but for your personal information.
