Privacy is the foundation of Hylon, treated as an engineering guarantee and a documented legal posture rather than a promise. This summary describes the approach. A full privacy policy will be published before launch.
On device by default
Your Personal AI learns from your data on your own device. Raw personal data never leaves the device.The network does not receive your messages, files, or activity.
What the network learns from
Only privacy preserving learned signal is shared, through federated learning with differential privacy and secure aggregation. Individual contributions are combined so that no single person's information can be reconstructed, and defenses are evaluated against membership inference and model inversion.
Legal basis
Hylon operates under a documented lawful basis with a data protection impact assessment and technical mitigations. We do not claim to be outside data protection law. We are built to be defensible within it, including the ability to honor access, deletion, and objection rights where they apply.
Site analytics
This website uses privacy respecting, cookieless analytics. We measure page views to understand which pages are useful. We set no cookies, store no cross site identifiers, and collect no personal data: only a sanitized page path is recorded, never the query string, the full URL, or your IP as an identifier. There are no third party surveillance SDKs. Your browser's Do Not Trackand Global Privacy Control signals are honored, and when either is set nothing is collected at all. With no cookie and no identifier there is nothing to consent to under GDPR.
Rewards and wallets
Wallets are non custodial by default. Where rewards are paid, wallet addresses may be screened against applicable sanctions lists. We collect the minimum necessary to operate the network and deliver rewards.
This is a working draft summary. The complete, binding privacy policy will be published and maintained with counsel.
