Security & your data
You're trusting us with calculations your product depends on. Here, in plain terms, is how we keep your requests and your data safe.
All systems operational · live status ↗Encrypted & signed
Everything travels over HTTPS, and we sign every API response so you can confirm a result came from us and arrived untouched.
Keys you control
Create as many keys as your plan allows, name them, and rotate or revoke any of them at any time. Connect an AI assistant and it stays read-only: it can calculate, never change your account.
Your data stays yours
Download everything we hold from your dashboard, or delete your account whenever you like. We never sell your data or use the birth details you send to train models.
Always the same answer
The engine is deterministic: the same inputs always return the same result. That makes what we compute easy to verify and easy to trust.
What we keep, and for how long
We hold on to as little as we can: your account details, and the usage records that power your dashboard and billing. The birth dates, times, and places you send to calculation endpoints are just inputs to a calculation, not a profile we build about anyone.
You're always in control. Export your data anytime, delete your account when you're done (with 30 days to change your mind), and your call log ages out automatically after 90 days, your usage history after 13 months.
Because the same inputs always produce the same result, we keep a short-lived cache so repeat calculations come back instantly. It is kept separately for each account, expires on its own within 30 days, and is never used for anything else. The privacy policy lists every period.
Who helps us run Asterwise
We work with a small, carefully chosen set of providers. Each one only ever sees the slice of data it needs to do its job, nothing more.
| Provider | What they do |
|---|---|
| Railway | Hosts the API, database, and cache |
| Cloudflare | Delivers the website and docs quickly and securely |
| Dodo Payments | Our merchant of record; handles checkout and billing, so card details never touch our servers |
| Resend | Sends account email like sign-in and password resets |
| Optional sign-in with your Google account, and website analytics on asterwise.com if you allow it | |
| Sentry | Error reports, with names, birth details, request values and credentials removed first |
| OpenStreetMap | Turns place names into coordinates; sees only the place text |
