This policy explains what we collect, why, and how you get it deleted. It applies to brisakorean.com and the emails we send you.
| Data | When | Why |
|---|---|---|
| Name, email | You submit the level test | To send your diagnosis and follow-up lessons |
| Test answers | You take the test | To generate your level and personal report |
| Goal, study habits, interests | You take the test | To personalise examples and recommendations |
| Country/region, timezone | Automatically, from your browser | Pricing, scheduling, and knowing which markets to serve |
| Referrer, campaign tags | Automatically | To know which channel you came from |
| Account (name, email, password), country, lesson progress, class bookings | You sign up and use the app | To run your lessons and classes |
| Voice recordings | You send a recording | To give you feedback (deleted within 90 days) |
We do not collect payment card details. Digital books and the Self plan are paid through Lemon Squeezy, who act as merchant of record. Teacher plans are paid through PayPal.
Until you ask us to delete it, or 24 months after your last interaction — whichever comes first. Records we are legally required to keep for tax purposes are retained for the period Korean law requires.
| Processor | What | Where |
|---|---|---|
| Google (Sheets, Apps Script, Gmail) | Lead records, email delivery | United States |
| Cloudflare | Website hosting | United States / global |
| Supabase | App accounts, lesson progress, class bookings, voice recordings | (Supabase 프로젝트 리전 확인 후 기입) |
| Lemon Squeezy | Payments, invoicing, tax | United States |
| PayPal | Payments for teacher plans | United States |
| Meta | Advertising measurement (only if enabled) | United States |
Your data is transferred outside Korea and outside the EEA to the processors above. We do not sell your data, and we do not share it with anyone not listed here.
Email koreanclass365@gmail.com with the subject "Delete my data" and we will remove your records and confirm within 30 days. No reason needed.
If you are in the EU or UK, you also have the right to complain to your local data protection authority. If you are in Korea, you may contact the Personal Information Protection Commission (privacy.go.kr, 국번없이 182).
When you submit the level test you consent to receive your report and follow-up lessons. Every email contains an unsubscribe link. Unsubscribing stops all marketing email immediately; you may still receive messages required to service a paid subscription.
We use browser localStorage to remember your language choice and where you first arrived from. This stays on your device and is never used to track you across other websites. If advertising measurement is enabled, a Meta pixel may set cookies — you can block these in your browser.
This service is intended for people aged 14 and over. We do not knowingly collect data from children under 14. If you believe we have, contact us and we will delete it.
Questions about this policy or your data go to the same address. We reply to all of them.
