Technical delivery data
When the Site is requested, the hosting and security infrastructure necessarily processes technical request data such as IP address, time, requested path, response status, browser user agent and referrer when supplied. Processing is necessary to deliver and secure the Site and to diagnose abuse or failures. The legal basis is the controller's legitimate interest in a reliable and secure service under Article 6(1)(f) GDPR.
Infrastructure providers act as technical recipients or processors. Data is retained only as required for delivery, security, incident handling and applicable legal obligations. Where a provider processes data outside the EEA, the controller relies on an applicable adequacy mechanism or appropriate safeguards.
Public demos
The decision and network-reference demos send the structured values entered in the browser to same-origin endpoints so the requested response can be calculated. The application does not create an account, attach a wallet, request a private key or persist those demo payloads in an application database. Normal security request logs may still contain request metadata, but not the submitted JSON body by design.
Do not enter personal data, secrets, private keys, seed phrases, real wallet balances, customer records or confidential transaction details. The demos are unsigned and have no production authority.
Contact and rights
If you contact the operator by email or telephone, the provided contact data and message are processed to answer the request and, where relevant, take pre-contractual steps requested by you. The legal bases are Article 6(1)(b) and (f) GDPR. Messages are retained only while required for the request, legal obligations or the defense of legal claims.
You may request access, correction, deletion, restriction, portability where applicable, or object to processing. You may also complain to the Austrian Data Protection Authority. Contact the controller using the details above.
