Tadak (“we”, tadak.app) is a Korean typing practice service run by an individual, Park Hyunjong. This policy explains what we collect, why, and the choices you have. We keep it short and collect as little as we can.
1. What we collect
- Account — when you start, we create an account for you automatically (a guest account). It has a random ID, the nickname you choose (optional), and your settings: keyboard type, sound, theme and meaning language.
- Learning records — steps you cleared, stars, scores and the time you played, and the words you missed (for review).
- Session — a login token. We store only a one-way hash of it, plus a short note of your browser type (user agent) so you can recognise your devices.
- Server logs — like any website, our servers record IP addresses and request times to keep the service running and secure.
- Sign-in — if you sign in with Google or LINE, we receive your account ID from that provider and, if you allow it, your email address. If you sign in with email, we store your email address and send you one-time codes; we keep only a hash of each code, and it expires after 10 minutes. We never receive or store a password.
We do not collect your real name, phone number, location or payment details, and we do not use advertising.
Analytics
We use Google Analytics to see which pages and lessons are used, so we can improve them. It records things like pages viewed, approximate country, device and browser type, using cookies (_ga). We turn off Google's advertising features and do not share this data for ads. Visitors in the EU, UK and Switzerland are asked first; anyone can choose Decline in the banner, and Tadak works the same either way. To change your choice, clear this site's data in your browser.
2. Why we use it
- To save your progress and let you continue on any device.
- To calculate points and show daily, weekly and monthly rankings.
- To bring back the words you missed for review.
- To keep the service secure and fix problems.
3. What others can see
Rankings are public: your nickname and points are shown to other users. Pick a nickname that does not identify you if you prefer to stay anonymous.
4. Stored on your device
Tadak saves a copy of your progress and your login token in your browser's local storage (tadak.v1, tadak.token, tadak.pending) and remembers your theme in a cookie (tadak-theme). These are needed for the app to work. If you allow analytics, Google Analytics also sets cookies (see Analytics above); we use no advertising cookies. Your cookie choice is saved as tadak.consent. Clearing your browser data removes them.
5. Service providers
We do not sell or share your information. Some providers process data only to run the service:
- Our server hosting provider (where the database and logs are stored).
- Cloudflare — delivers lesson audio and pictures.
- Google Analytics — usage statistics, if allowed.
- jsDelivr — delivers the web font.
- Resend — sends sign-in code emails (only your email address and the code).
- Google and LINE — only if you choose to sign in with them.
Some of these providers may process data outside your country, including in the Republic of Korea and the United States.
6. How long we keep it
We keep your account and records until you delete them or ask us to. Accounts with no activity for 12 months may be deleted. Server logs are kept only for a limited time, for security and troubleshooting. Where the law requires us to keep something longer, we keep only that, only for as long as required.
7. Your rights
You can ask to see, correct, export or delete your information, or ask us to stop using it. “Start over” in Me clears your stars and points at any time. For anything else, email us — we reply within 10 days.
8. Children
Tadak is not meant for children under 14 without a parent or guardian's consent. If you believe a child has given us information without consent, contact us and we will delete it.
9. Security
Connections are encrypted (HTTPS), login tokens are stored only as hashes, and access to the database is restricted. No system is perfect, but we work to protect your information.
10. Changes
If we change this policy, we will update the date above and, for important changes, let you know in the app.
