Privacy

Costslice is a usage meter for LLM APIs. The proxy forwards your provider request and records a small usage row after the provider responds. We do not store prompt bodies or completion bodies. We do not train models on customer data — we do not keep payloads to train on.

Account data we keep: email, workspace name, membership, hashed API keys, optional tenant plan prices, and usage metadata (tokens, model, tenant, feature, env, cost, latency, status). Billing is handled by Stripe.

Use an opaque internal tenant id in x-cs-tenant, not an email address or other personal data.

We do not claim SOC 2 or HIPAA. A data processing agreement can be provided later; this page is the MVP privacy notice. Contact hello@costslice.com.
