4. We do not sell your data

We do not sell, rent or share your personal data with third parties for commercial purposes.

5. Payments with Stripe

Payments are processed by Stripe, Inc. Khristallos does not receive or store your full card numbers. Stripe handles this data under its own privacy policy.

6. Service providers

We use trusted providers that process data only to deliver their service to us: Stripe (payments), Formspree (form submissions), Zoho (email) and Cloudflare (website hosting and security). Some may process data outside your country, with the safeguards required by law.

7. Confidentiality of client data

Data you share with us for a project is used solely for that project, with restricted access. We do not share it with third parties unless required by law. When the project ends, we delete or return it as agreed; unless otherwise agreed, we delete it within 90 days of delivering the report, keeping only the billing records required by law.

8. How long we keep it

We keep contact data for as long as needed to handle your request or maintain the business relationship, and billing data for as long as the law requires.

9. Security

We apply reasonable technical and organizational security measures to protect your data. No system is infallible, but we work to minimize risk.

You may at any time request access to, correction or deletion of your data, object to its use or unsubscribe from our communications by emailing [email protected]. We will respond within a reasonable time and, in any case, within the deadlines set by applicable law.
