Not disclosed
No region-pinning controls disclosed.
Prompt retention
Retained · 30 days (non-ZDR requests)
Per Wafer's stated privacy posture (as summarized on Opper's provider page; wafer.ai/privacy-policy returned 404 on 2026-09-02), non-ZDR request logs are anonymised and deleted within 30 days; ZDR requests are not retained. ToS confirms prompts/completions are processed 'solely as needed to operate, secure, and bill the Service'.
Trains on API data
No
Wafer states it never trains the models it serves on customer prompts or completions (per its published privacy posture; the policy page itself was unreachable at time of check).
Zero data retention
Available
Wafer Serverless supports Zero Data Retention for every model marked 'ZDR supported' in app.wafer.ai; a self-serve paid Privacy tier includes ZDR. Not verified directly on wafer.ai because /privacy-policy and /dpa returned 404 on 2026-09-02.
