AI privacy
A practical AI data residency guide for API and enterprise AI buyers: regional storage, inference location, retention, zero data retention, DPAs, privacy controls, and vendor review.
Comparison
| Option | Best for | Strengths | Tradeoffs | Use when |
|---|---|---|---|---|
| Storage data residency | Choosing where customer content is stored at rest | Helps meet regional data sovereignty and customer procurement expectations. | Storage location may not answer processing, logging, support, or subprocessor questions. | Customer content, files, conversations, or generated artifacts must remain in a region. |
| Inference or processing residency | Workloads requiring model execution or processing to occur in-region | Addresses stricter requirements where data movement during processing matters. | May have limited provider, region, model, or feature availability. | A contract or regulation cares where processing happens, not only storage. |
| Zero or reduced retention | Sensitive API workloads where prompts and outputs should not be stored after processing | Reduces exposure from retained content and logs. | May limit abuse monitoring, debugging, support, features, and eligibility. | The workload contains sensitive customer, health, legal, financial, or confidential business data. |
Buyers often ask one question: where is our data? A useful review breaks that into storage, processing, retention, training use, logs, support access, backups, subprocessors, and deletion behavior.
Regional controls can affect model availability, tool support, file search, image generation, logging, and enterprise features. Do not assume every feature works in every region.
Policy pages are only useful when engineering and procurement convert them into configuration, monitoring, and contract terms. The real control is what your app does by default.
Decision Rules
Do not approve an AI vendor until storage, processing, retention, and training-use questions are answered separately.
Use region-specific projects or endpoints for regulated customer content when available and required.
Use reduced retention or zero-retention paths for the most sensitive API traffic when eligible.
Track feature and model availability by region before committing to customers.

OpenFAQ
No. Data residency is about where data is stored or processed. Zero or reduced retention is about whether prompts, outputs, or logs are stored after processing.
Not always. Some providers separate storage residency from processing or inference residency. Check official docs and contract terms for the exact feature.
Ask where prompts, outputs, files, embeddings, logs, backups, and metadata are stored and processed, how long they are retained, and whether customer data is used for training.
