Privacy Policy

How we handle the data that flows through the Asterwise API, MCP server, and dashboard, written for the engineers who have to trust it.

Last updated 28 May 2026 · Asterwise Labs Private Limited

Who we are

This service is operated by Asterwise Labs Private Limited ("Asterwise", "we", "us"), incorporated in India (CIN U62011HR2025PTC136714, GSTIN 06ABDCA8258P1Z2). This policy covers the API at api.asterwise.com, the MCP server at mcp.asterwise.com, the dashboard, and our marketing site.

What we collect

We collect only what we need to run an API business:

  • Account data: your email, name, hashed password (or Google OAuth identifier), and the API keys we issue you.
  • Usage metadata: for each request, the endpoint called, a timestamp, response status, latency, and your key ID. This powers your usage dashboard and our rate limiting.
  • Billing data: your plan, subscription state, and invoices. Card details are handled by our payment processor; we never see or store full card numbers.

Calculation inputs

Birth dates, times, and locations you send to calculation endpoints are inputs to a deterministic computation, not a profile we build about a person.

Because the same inputs always produce the same signed result, we keep a calculation cache (default 30-day TTL) keyed on a hash of the request, so a repeated calculation can be served instantly. The cache stores the computed result against that hash; it is not linked to an identity or browsed for any purpose. You can purge the data associated with a key at any time from your dashboard.

How we use it

  • To operate, secure, and rate-limit the API and MCP server.
  • To show you accurate usage and billing in the dashboard.
  • To send transactional email (verification, password resets, billing) via our email provider.
  • To debug and improve reliability. We do not sell personal data, and we do not use your calculation inputs to train models.

Sub-processors

We rely on a small set of infrastructure providers, each handling a specific function: cloud hosting and databases for the API, a CDN for the marketing and docs sites, a transactional email provider, and Dodo Payments as merchant of record for subscriptions. Each receives only the data required for its role.

Retention

Account and billing records are kept for as long as your account is active and as required by Indian tax and company law. Request logs are retained on a rolling window for operational and security purposes. Cached calculations expire on their TTL. When you delete your account from your dashboard, we remove your personal data except records we are legally required to keep.

Your rights

You can access, export, correct, or delete your data from your dashboard. To exercise any right or raise a concern, email us and we will respond to verified requests within a reasonable period.
