How your data is protected at every step.

Encryption

TLS 1.3 enforced in transit. AES-256 encrypted storage at rest. No plaintext connections accepted.

Access controls

Authentication required on all endpoints. Row-level security on every table. Service access restricted to backend routes only.

API key storage

Keys stored as SHA-256 hashes. Plaintext shown once on creation, never stored or logged after that.

Forecast delivery

Precomputed on schedule and served from cache. API queries do not trigger model inference. No customer-specific training.

Availability

99.9% monthly uptime target across Developer, Team, Growth, and Enterprise plans. Service credits available under negotiated Enterprise terms; see SLA for measurement and remediation.

Data residency

All customer data, accounts, API keys, forecast metadata, is stored in the United States on Supabase (AWS US regions) and served via Vercel's North American edge. No data leaves US infrastructure.
