Privacy Policy

Last updated October 22, 2026

This page explains what Ksty.ch stores about you and why.

What we collect

• Account: your email address, and your name if you add one. Sign-in uses one-time codes; we don't need a password.
• API usage: for each call — time, API and endpoint, the key used, status, latency, credits charged, the calling IP address and the country it resolves to. We use this for billing, abuse detection, geo rules and the usage charts you see.
• Payments: handled by Stripe. We store the payment reference and amount; card details go to Stripe and never reach our servers.
• Request content: what you send to an API is processed to produce the response. The usage log records the facts above about each call, not the request or response bodies.

How long we keep it

Detailed usage logs are kept for 90 days, then reduced to daily totals. Payment records are kept as long as accounting rules require. Closing your account signs out every device and removes your access.

Cookies

We use a session cookie to keep you signed in and remember your light/dark theme choice in your browser. No advertising or third-party tracking cookies.

Sharing

We don't sell your data. Processors we rely on (payments, email delivery, and the upstream providers that serve some APIs) receive only what they need to do that job.

Your choices

You can download your usage and billing history from the dashboard, and close your account from Account settings. For anything else — a copy of your data, a correction, a deletion request — write to api@kstych.com.
