Cross Border Transfer of Personal Data
In general, the Company does not transfer or disclose your personal data to recipients located outside the country, unless such transfer is necessary for business operations, such as the use of cloud service providers located overseas, or where the transfer is required to fulfil the purposes of personal data processing previously communicated to you.

- Countries or jurisdictions that have been recognized as providing an adequate level of data protection under applicable laws, or
- Recipients who are bound by legally enforceable data protection agreements, such as a Data Processing Agreement (DPA) or other legally required standard contractual terms.
