International Transfers

Some processors, including Perso.ai, Google, Vercel, and Neon, may be located outside Korea or use global infrastructure. Transferred information is limited to what is necessary for the purposes above and is handled under each processor’s security policies and contractual or policy safeguards.

• Transferred items: account information, YouTube API data, dubbing/translation inputs and outputs, job records, and payment information needed by the relevant processor
• Transfer purposes: sign-in, hosting, database storage, AI processing, YouTube integration, payment approval, and settlement
• Retention period: generally the shorter of the retention period in this Policy or the period needed by the processor to provide its service

We do not disclose data to other third parties without your explicit consent, except where required by a lawful request.

• account information: retained in a recoverable pending-deletion state for 7 days after withdrawal, then deleted automatically if you do not sign in again during that period
• OAuth tokens: deleted immediately from server storage when you disconnect YouTube, revoke Google permissions, or request account withdrawal
• YouTube channel/video cache: retained only as needed for display and reliability, and deleted or no longer refreshed upon request
• dubbing job records, upload queue records, and YouTube upload records: retained in pending deletion for 7 days after withdrawal, then deleted after the recovery period
• payment and billing records: contract, withdrawal, payment, and supply records may be retained for 5 years, and consumer complaint or dispute records for 3 years under Korean e-commerce law. After withdrawal, user identifiers are anonymized and only the minimum information needed for settlement and disputes is retained separately
