Privacy

How this website handles customer accounts, enquiries, product interests, and operational records.

Effective 25 October 2026 · Website accounts and enquiries

What we collect

Account registration stores your name, email, password hash, optional company, terms acceptance, and email-verification status. We store your chosen product interests separately. Enquiries store the details and message you submit, even if you do not create an account.

Why we use it

We use account information to authenticate you, maintain your profile, and send verification, recovery, and account-security messages. Product interests let us understand demand and contact you about the specific product you selected. They do not automatically subscribe you to a general newsletter.

Email and operational records

Messages are delivered through the configured SMTP provider. Pending outbound messages are encrypted at rest; the application holds the key needed to send them. Delivery records retain status and limited error information. Authentication tokens are stored as hashes separately and expire after use or their validity period. Successful or permanently failed queue payloads are cleared.

We use essential session cookies and limited security/rate-limit records. No analytics, advertising cookies, or payment-card collection are included in this release. Hosting and email providers necessarily process traffic and delivery data as part of operating their services.

Retention and account closure

You can withdraw product interests and close your account from the dashboard. Closure removes your profile and interests, revokes sessions and tokens, and removes associated queued email. Standalone enquiries and limited operational delivery/security records may remain for handling correspondence, investigating abuse, and maintaining service records. Security rate-limit records and expired sessions/tokens are pruned by scheduled cleanup. Backups may retain deleted data until replaced under the hosting operator’s backup schedule.
