Upstage: data residency & retention
Headquarters
🇰🇷 South Korea (Other)
Where inference runs
Not disclosed
Controller: Upstage Co., Ltd., Seoul, Republic of Korea (Korean law; California law for US customers). No specific inference region is published; the privacy policy discloses overseas transfers to US-based processors including AWS, Microsoft Azure and RunPod, so processing is not Korea-only.
Region pinning
Not disclosed
No region-pinning controls disclosed; users may refuse overseas transfer via the Help Center but with service restrictions.
Prompt retention
Not retained
ToS Art. 22 (paid API): 'the company does not store member input/output data' except where operationally necessary. But per the privacy policy: async-API inference results kept 30 days, Console Playground data kept until membership withdrawal (non-members: 1 year), Solar Chat demo 3 months, free-tier API data 'until end of service provision'. Azure OpenAI / OpenAI-routed models add their own up-to-30-day retention.
Trains on API data
No
Paid services (ToS Art. 22): input/output data is not used for service improvement or AI model training without separate prior consent. Exception: free services/free-tier data 'may be used for service provision and improvement, and AI technology R&D (including training)', and Solar Chat demo inputs may be used for training after PII masking.
Zero data retention
Not disclosed
No formal ZDR offering published; paid API defaults to not storing I/O per ToS, but no contractual ZDR product or enterprise ZDR page was found.
