Privacy Policy

Last updated: July 2026

Starwell is built by the Starwell team (Toronto, Canada). We serve public official statistics, so the service needs very little of your data.

What we collect

• Waitlist and update signups: your email address and, if you choose to provide them, a short note about what you are building and what data you need. Used to grant access, send occasional product updates, and decide which sources to add next.
• API key requests: the email address you provide when requesting a key, kept for abuse prevention and account contact.
• API and MCP usage metadata: for each request we log the endpoint or tool called, the data source and series requested, response latency, an API key identifier when a key is used, and a one-way hashed network identifier for anonymous rate limiting and abuse prevention. We do not log request contents beyond this, and we do not build advertising profiles.
• Questions sent to the answer endpoint: the question text is processed to compute the answer and may be cached (with its computed result) so repeated questions are served faster. Do not include personal or confidential information in questions.
• Monitor webhooks: the webhook URL you register, used only to deliver the alerts you asked for.
• API keys: stored only as cryptographic hashes. We cannot recover a lost key; we issue a new one.

What we do not collect

• No personal data beyond the above. Starwell serves aggregate official statistics and never handles microdata about individuals.
• No third-party advertising or analytics trackers on this site.
• We do not sell user data.

Processors we rely on

Some vendors process data on our behalf: model inference for the answer endpoint (Anthropic), email delivery (Resend), and our hosting and database provider. Each receives only what its function needs.

Retention

Waitlist entries are kept until you ask to be removed. Usage metadata is kept in aggregate for capacity planning and to decide which sources to add next; request-level records are pruned on a rolling basis. Cached answers expire automatically when the underlying official data is revised or on a fixed schedule.

Your choices

Email hello@starwell.dev to unsubscribe from updates, delete your waitlist entry, revoke an API key, or ask what we hold about your email address. We respond within 30 days.

Changes

We will update this page when practices change and adjust the date above. Material changes affecting API users are announced through the update list.
