People and data

How we handle contributors, data and contracts

Consent first

Every voice contributor signs an agreement that states how their recordings will be used, including AI training where the project requires it. We follow China’s Personal Information Protection Law and local rules such as Indonesia’s Personal Data Protection Law.

Controlled access

Project files are kept in access-controlled storage, shared only with the people working on the project, and deleted after the retention period agreed with the client.

Clear contracts

Each project runs on a written agreement with a defined scope, price and acceptance criteria. We invoice in CNY or USD.
