Your chats with AI and the AI’s evidence or summary text never reach our server. Scoring happens in your browser.
No names, phone numbers or accounts. We don’t store raw IP addresses.
2. What we store and why
Statistics (optional, off by default): your 6 scores (numbers), AI-side MBTI, the MBTI you pick (optional) and confidence — used for the real distribution and ranking.
When you start the 30-day challenge: starting scores, weakest skill, AI-side MBTI, language and time zone, which days you completed, difficulty answers, re-test scores and the ad source label — used to run the challenge and show your growth.
Email (optional): only if you ask for reminders; used only for the daily mission email and resending your link.
Spam protection: a one-way hash of your IP mixed with the date, valid for one day — it can’t follow you across days.
Payment (if paid mode is turned on): card details are handled by Toss Payments, never by this site. We keep only the payment confirmation id.
3. Retention and deletion
Statistics: deleted as soon as you untick the box.
Email: deleted immediately with “Stop and delete my email” on the challenge page; reminders stop automatically when the challenge ends.
Challenge records: deleted one year after your last activity, or earlier on request.
4. Processors
Cloudflare (hosting, database), Resend (reminder email, if requested), Toss Payments (payment, if enabled).
