We share personal data only where required to operate the service, such as:

• Hosting/infrastructure and database providers.
• Email delivery providers used for account and security communications.

We do not sell personal data. We require processors to handle data under written contractual safeguards and security obligations.

We may retain limited data longer where required by law, for legal claims, or to prevent fraud and abuse.

We use technical and organizational safeguards including access controls, encryption in transit, environment hardening, and security monitoring. No internet system is 100% secure, but we continuously improve protections.
