3. Purposes and legal bases for processing
We process your personal data for the following purposes:

Processing is based on your consent, the need to perform a contract, our legal obligations, or other cases permitted by law. If the processing purpose changes, we will notify you and obtain your consent as required.
4. Sharing personal data
We do not sell your personal data. Data is only shared in the following cases:

Where personal data is stored or processed on infrastructure located outside Vietnam (e.g. international cloud services), we will carry out the required cross-border transfer impact assessment procedures and related obligations under Vietnam's personal data protection laws, and apply commensurate safeguards.
6. Retention period
Personal data is retained for as long as necessary to fulfil the processing purposes stated in this Policy, or for the period required by law (e.g. accounting document and contract retention obligations).
