Privacy Policy
Effective 1 November 2026
InferStack ("we") provides AI model inference through an API, mainly to customers of OpenRouter. This policy explains what we process, what we keep, and for how long.
1. Prompts and completions
- Prompts, images and generated completions are processed in memory only to produce the response.
- We do not store, log or retain prompt or completion content.
- We do not use customer data to train or fine-tune models, and do not sell or share it.
- Images sent by URL are downloaded by our gateway, used for that request, and discarded.
2. What we do keep
For billing, capacity planning and abuse prevention we keep request metadata:
| Data | Retention |
|---|---|
| Request ID, timestamp, model, input/output token counts, latency, HTTP status, amount billed | 13 months |
| Aggregated metrics (request rates, error rates, throughput), with no per-request content | 30 days |
Request metadata does not contain prompt text, completion text or images.
3. Where processing happens
- Inference runs on GPUs located in Canada.
- Some GPU capacity is rented from third-party infrastructure providers. Those providers operate the physical hardware but receive no data from us beyond the computation itself.
- Network traffic passes through Cloudflare, which terminates TLS on our behalf.
4. Who we share data with
- OpenRouter: request metadata, for billing.
- Infrastructure providers (Cloudflare, GPU and server hosts): only as needed to run the service.
- Authorities: where required by Canadian law.
5. Your rights
Because we do not store request content, there is generally no personal content for us to access, correct or delete. For questions about request metadata, or a complaint under Canada's Personal Information Protection and Electronic Documents Act (PIPEDA), contact hello@inferstack.ca.
6. Security
All traffic is encrypted in transit (TLS). GPU servers accept no inbound connections from the internet and are reachable only over a private encrypted network from our gateway.
7. Changes
We will post updates on this page with a new effective date.
