Privacy Policy

We collect the following information when you use Behavioural Engines:

• Account data — name, email address, and authentication credentials managed by Clerk
• Simulation data — parameters and results of simulations you run, stored in our database (NeonDB/PostgreSQL) against your user ID
• Usage data — daily simulation counts stored ephemerally in Redis for quota enforcement (auto-expires at UTC midnight)
• Payment data — billing is handled entirely by Stripe. We do not store card details. We store your Stripe subscription status in your Clerk account metadata
• Analytics — anonymised page view data via Google Analytics

• To provide and operate the simulation platform
• To enforce fair usage quotas

Simulation data is stored in a PostgreSQL database hosted on NeonDB (EU region). Authentication is handled by Clerk with industry-standard encryption. Payments are processed by Stripe with PCI-DSS compliance.

Redis quota data expires automatically and contains no personally identifiable information beyond hashed IP addresses for anonymous users.

We use the following third-party services:

• Clerk — authentication and user management
• Stripe — payment processing
• Railway — backend hosting
• NeonDB — database hosting
• Google Analytics — anonymised usage analytics

Each provider operates under their own privacy policy and data protection standards.

Simulation history is retained for the lifetime of your account. You may request deletion of your data at any time by contacting us. Account deletion removes all associated simulation records.

Under UK GDPR and applicable data protection law, you have the right to: access your data, correct inaccuracies, request deletion, and object to processing. Contact us to exercise any of these rights.

We use session cookies required for authentication (via Clerk) and analytics cookies (via Google Analytics, which can be blocked with standard browser controls or extensions). We do not use tracking cookies for advertising.
