Privacy policy

Who is responsible: Anastasia Kalacheva. Contact: store@aiusecasestore.com.

What this site stores, and why:

• Your email address — when you unlock a use case, join a waitlist, follow for updates, or send feedback with a reply address. Used to give you access, save your progress, and (waitlist/follow) notify you about the thing you asked about. Waitlist and follow subscriptions use double opt-in: you receive updates only after clicking the confirmation link we email you, and you can unsubscribe from any update email. Legal basis: performing what you requested (Art. 6(1)(b) GDPR) and your consent (Art. 6(1)(a)).
• Your progress — which use cases you unlocked and which steps you completed, linked to your email.
• Feedback messages — what you write in the "Write to me" form.
• Anonymous usage statistics — page visits with an anonymized identifier (a hash; no name, no full IP stored) and the referring site, plus cookieless visit counting through Umami (see below). Used to understand which use cases help people. No advertising trackers, no cookies beyond one sign-in cookie.

Sign-in cookie: after you click a sign-in link, a cookie keeps you signed in (up to 1 year). It contains only your account reference.

Who else processes data:

• Resend (resend.com) delivers the emails this site sends, and receives emails you send to store@aiusecasestore.com.
• Railway (railway.com) hosts the site and the database. Servers are located in the USA; the transfer is covered by Railway's data processing agreement with EU standard contractual clauses.
• Umami (umami.is, EU-hosted) counts page visits and clicks without cookies and without storing personal data.
• Gumroad (gumroad.com) handles purchases as the seller of record when paid checkout is active; their own privacy policy applies at checkout.

Your rights (GDPR): access, correction, deletion, restriction, portability, objection, and complaint to a supervisory authority. For any of these, email store@aiusecasestore.com — deletion requests are honored manually within 30 days.

Data is not sold or shared beyond the processors listed above.
