Privacy Policy

We collect the minimum needed to run the service — and we never see your card number.

What we collect

• Email address — for sign-in (magic link), watchlist alerts, and billing receipts.
• Your API access key — the personal key that connects our data to your AI tools. It, and the usage counts tied to it, are stored in our database to authenticate you and enforce fair-use limits.
• Your watchlist — the tickers you choose to monitor.
• Usage counts — number of checks used, to enforce fair-use limits.
• Support & access-link requests — if you email us or ask for your access link to be re-sent, we log that request (your email address) to process it.

Where it is stored

The service runs on Cloudflare. Your email, API key and usage counts are held in a Cloudflare D1 database; reports and site pages are served from Cloudflare's edge. We use aggregate Cloudflare Analytics only (no cross-site tracking cookies).

What we do not collect

Payment card details are handled entirely by Polar and its payment processor (Stripe) — they never reach our servers. We do not sell or share personal data with third parties for marketing.

Your choices

Email support@koreastockcheck.com to export or delete your data. Unsubscribing stops alerts immediately; account data is deleted within 30 days of a deletion request.
