นโยบายความเป็นส่วนตัวPrivacy Policy

We only collect what's needed to run the service: your email (to send your access link), payment details (handled entirely by Stripe — we never see or store your card number), a device identifier (to enforce the per-purchase device limit), and a record of the purchase itself.

Your data is used to deliver your access link, confirm your purchase, help you if you contact us, and prevent one link from being shared beyond the allowed number of devices. We never sell or share your data for advertising.

We rely on a small set of trusted services to run: Stripe (payment processing), Resend (email delivery), Supabase (data storage), and Vercel (web hosting). Each has its own privacy policy.

The app stores some data locally on your device (learning progress, unlock status). This stays on your device — it's not used for tracking or ads.

You can ask what data we hold about you, or ask us to delete it, at any time — just reply to your purchase confirmation email.

This app isn't designed for children under 13 without parental supervision.

We may update this policy from time to time. Changes will be posted here.
