Cassandra plugin privacy

How data is handled in the engineering preview.

Project contact

Cassandra is an independent project operated by Nima. Contact contact@projectcassandra.uk with privacy questions or requests.

Guest examples

The guest tool receives only a selected example topic. Cassandra stores aggregate run counts by topic. The application does not collect full ChatGPT transcripts or guest account identifiers through that tool.

Render may process technical connection information to host and protect the service. OpenAI processes your ChatGPT interaction under its own privacy policy.

Private account preview

Auth0 handles sign-in. Cassandra uses the account identity and permissions to restrict access to account-owned synthetic machine definitions and reference artifacts. Measurement rows sent to account analysis tools are processed to perform the requested calculation. Reference artifacts and machine definitions are stored for the preview.

Submit synthetic data only. Preview storage is temporary and can reset when the service restarts or redeploys. The application does not pool customer data for cross-customer model training.

Website and hosting

Cloudflare hosts this public presentation. The site does not collect passwords locally or provide plant-data upload or payment forms. The website has no sign-in. Its contact form prepares a visitor-reviewed email draft. Website interactions use browser code and do not submit plant measurements. The cooling and heating demos use precomputed synthetic reference outputs. Slider values remain in the page and are not sent to an analysis service. Hosting providers may process connection data for delivery and security.

See Cloudflare privacy information, Render privacy information and Auth0 provider privacy information.

Support and your requests

Emailing support sends your message and contact information to the support mailbox. Include only information needed to resolve your request. Contact contact@projectcassandra.uk for access, correction or deletion. We may need to verify account ownership. Provider-held records follow the relevant provider’s retention practices.

This notice covers the current engineering preview. A release accepting measured customer data will require an updated notice and defined retention and recovery arrangements.

Website contact

The contact form prepares an email draft locally in your browser. You choose whether to open and send the draft using your email provider. Cloudflare Email Routing forwards messages sent to contact@projectcassandra.uk to the Cassandra support inbox so we can reply. Do not include confidential plant records, passwords or payment details.

Existing private ChatGPT connections use Auth0 separately.
