Privacy Policy

Last updated: May 27, 2026

1. Who We Are

Currency Strength Radar is operated by a sole trader registered in Slovakia. Contact: [email protected]

2. What Data We Collect

  • Email address and nickname (on registration)
  • Subscription status and plan type
  • Chat messages sent to the AI assistant
  • Community votes and comments you submit
  • Basic usage data (page visits via Vercel logs)

3. How We Use Your Data

  • To provide and maintain the service
  • To process your subscription via Stripe
  • To send transactional emails (Resend)
  • To power the AI chat assistant (Anthropic API)

4. Third-Party Services

We share data with the following processors:

  • Stripe — payment processing (stripe.com/privacy)
  • Google Firebase — data storage, servers located in the United States (nam5/us-central)
  • Vercel — hosting and delivery, and privacy-friendly Web Analytics (page views, referrers, approximate location and device type; no cookies, no cross-site tracking) (vercel.com/docs/analytics/privacy-policy)
  • Resend — transactional email
  • Anthropic — AI chat processing (your messages are sent to Anthropic's API)

5. Data Transfers

Your data is stored on servers in the United States. By using CSR, you consent to this transfer. We rely on standard contractual clauses where applicable under GDPR.

6. Data Retention

We retain your data for as long as your account is active. You may request deletion at any time by emailing [email protected].

7. Your Rights (GDPR)

If you are in the EU/EEA, you have the right to access, correct, delete, or export your personal data. Contact us at [email protected].

8. Cookies

We use only essential cookies. We do not use tracking or advertising cookies, and we do not share any cookie data with third parties.

  • __session — keeps you signed in. Only set once you log in.
  • csr_sid — a randomly generated identifier set for all visitors, including those without an account. It contains no personal data and is used to apply fair-use limits on how often data can be refreshed, which protects the service from automated scraping. It expires after 30 days.

9. Anonymous Usage Statistics

You can browse currency scores, news, the calendar and score history without an account. For visitors who do, we record aggregate daily counters only — for example, how many sessions started on a given day, how many people reached the sign-in prompt for the AI assistant, and how many times each page on the site was viewed. These counters are totals per day and per page, not per visitor: we do not keep a record of which pages any individual visitor looked at, their IP address, or any other trail of their session, and nothing here can be traced back to a person. Because this data is anonymous statistical data rather than personal data, it does not require consent, and there is nothing in it for us to delete on request.

Separately, Vercel's Web Analytics (see Section 4) provides us aggregate, privacy-friendly traffic statistics such as visit counts, referrers and approximate country/device — collected without cookies and without tracking individuals across sites.

10. Changes

We may update this policy. We will notify you by email for material changes.
