Sub-processors
Last updated: October 27, 2026
Esan engages the following third-party processors to deliver the Service. Each processor is bound by a written agreement compliant with Article 28 of the EU General Data Protection Regulation (GDPR), including obligations of confidentiality, security and data protection by design.
We notify connected users by email at least 14 days before adding or replacing a sub-processor that processes personal data, so you can object before the change takes effect. Past versions of this list are archived and available on request to support@esan.ai.

Transfers outside the EEA rely on the safeguards in each provider's data processing terms, mainly the EU Standard Contractual Clauses or the EU-US Data Privacy Framework.
For the payment-card, identity-verification and bank-account data you provide directly to Stripe, Stripe acts as an independent data controller under its own privacy policy (see our Privacy Policy, Section 5).
