Data storage and security

Your contact form submissions are stored in a secure database hosted in the EU (Neon PostgreSQL). Analytics data is processed by PostHog's EU servers. We implement appropriate security measures to protect your data.

CamNexus client portal

People we invite to the CamNexus portal sign in with a link sent to their email. For this we keep their email address, their company and their sign-in sessions, including an identifier of the browser they signed in from (Neon, EU).

In the compare screen, the two pictures a user uploads are made at most 1280 pixels wide in their browser and sent over an encrypted connection through our website (Vercel, Frankfurt) and Cloudflare to the CamNexus server (Contabo, EU). They are compared in memory and dropped as soon as the result is returned. They are not stored, not logged and not used to train CamNexus. We record who ran a comparison, when, and its result, and that the user confirmed the note shown before their first comparison.

Camera pictures can show people and number plates. Users may upload only pictures they are allowed to share with us.
