Site data and registration status.

Site data notice · updated 2026-09-27 · website scope

Email registration is paused and participation applications are closed. You can read the public pages without accepting a policy or providing an email address.

01Registration status

There are no public email registration or application forms. The email subscription endpoint rejects new registrations, including requests sent directly to it. The participation endpoint remains closed.

Project and publication updates will appear on this site.

02Visiting the site

Opening a page sends a request to the website and its hosting infrastructure. Request logs may contain your IP address, the requested path and the time of the request. The hosting provider’s log retention has not been verified for this notice.

The published static pages use self-hosted page assets. The site code does not include analytics or advertising trackers, and there is no public visitor account system.

Following a link to another website takes you to a service with its own data practices. External links do not require you to provide information to Centram.

03Browser preferences and cookies

Webπ records its language selection in the page URL. Blog pages may read a saved language preference and save an appearance preference in your browser’s local storage. The site code does not send those local preferences to the server.

The former policy acceptance screen has been retired. An older acceptance entry may remain in your browser’s site data; the current site does not read or update it. Clearing site data removes locally saved preferences and that older entry.

Cookies are used for authenticated administrator sessions. The public static pages do not set a visitor tracking cookie.

04Earlier submissions

Closing registration does not delete earlier email subscriptions or participation applications. These records remain in the existing database and are accessible through authenticated administrator tools.

Existing subscriber records can be exported or sent to an operator-configured spreadsheet service. Resend may deliver queued administrative notifications about earlier applications. The hosting infrastructure also processes database records.

This notice does not claim that earlier records have been erased or assign them a new retention period.

05Before registration reopens

Operator details and a public privacy contact have not yet been confirmed for publication. New registrations remain paused until those details and a complete data policy are published, including purposes, recipients, retention and a working contact for requests concerning personal data.

This page describes the current website behavior. It does not ask you to agree to an unfinished policy.

06The node software

The website and the node software are separate systems. The following describes design intent for software run on your own machine; it is not a guarantee of a released or independently audited product.

The design aims to keep personal inputs and the model that learns from them on your device. Peers may see network identifiers, connection IP addresses, reputation information and signed contribution metadata.

Keeping raw data local does not, by itself, prevent private information from being inferred from shared representations or model updates. Information flows and possible reconstruction must also be evaluated.

Privacy across physically separate machines has not been demonstrated by this website. Read the privacy design principles and implementation status before treating those goals as capabilities.
