SiliconFlow: data residency & retention
Headquarters
🇸🇬 Singapore (Other)
Where inference runs
Not disclosed
International entity is SILICONFLOW TECHNOLOGY PTE. LTD. (Singapore, PDPA-governed); no data center or processing locations disclosed (dc:US hint unverified). Privacy policy allows sharing 'whether within or outside Singapore' with no geographic detail. Chinese-origin company: ToS states 'The Services are not available for users located in the territory of mainland China and users in China may access our services through https://siliconflow.cn' — the intl API is a separate offering from the .cn service; no explicit mainland-transfer language either way.
Region pinning
Not disclosed
No region selection described in policy, ToS, or site.
Prompt retention
Not retained
Homepage privacy claim: 'No data stored, ever. Your models stay yours.' — but this is marketing copy not mirrored in legal docs. Privacy policy only says 'we have no obligation to store your Interaction Data'; ToS says services 'strictly execute your instructions for processing Interaction Data' except for law/troubleshooting. No retention window or formal commitment published.
Trains on API data
Not disclosed
Neither privacy policy nor ToS addresses use of customer inputs for training.
Zero data retention
Available
Marketed as no-storage by default ('No data stored, ever'), but not backed by explicit contractual language in privacy policy or ToS.
