SecurityOps acts as controller for enrollment data. We process name, email, order/payment references, access logs and support messages to perform the contract, prevent fraud, secure the service, meet legal obligations and exercise rights. We do not sell data or use advertising trackers.
Payment providers process financial data under their own notices. Necessary records are retained for contractual, tax, fraud-prevention and limitation periods, then deleted or anonymized. Infrastructure providers may process limited technical data, including internationally, with applicable safeguards.

You may request confirmation, access, correction, information about sharing, portability where applicable, objection, revocation of consent and deletion when legally available.

Security controls include access restriction, isolated services, encrypted transport, backups and audit logs. No system is risk-free; incidents with relevant risk or harm will be handled and communicated as required. Last updated: 31 August 2026.
