Frequently asked
Everything you'd want to ask first
Does hieu.asia predict the future?
No. We don't claim to predict the future. The goal is to help you see your behavioral patterns and innate tendencies clearly, so you can make better decisions yourself.
I don't know my exact birth time — can I still use this?
Yes. You can start with MBTI, Big Five, Numerology, and Face Reading without a birth time, and update your chart later once you find more accurate information.
How is my personal data protected?
Data is transmitted over encrypted TLS. Reports and exported files are stored on infrastructure with encryption at rest (Cloudflare R2 / Supabase Storage). We don't sell your data or use it to train models. You can delete your account anytime from your Account page.
How much does it cost? Is there a free plan?
Standard is free — the intake survey plus basic lookup tools. Premium 99.000₫ one-time (1 full chart + PDF + 3 Mentor questions). Mentor 199.000₫/month or 1.990.000₫/year (30 Mentor questions/day + yearly-cycle readings). Lifetime 4.990.000₫ one-time.
Can I cancel anytime?
Yes. Cancel from your Account page — your plan stays active until the end of the paid period, no auto-renewal. Within 24 hours of purchase, if your report hasn't been generated yet, you get a full refund, no questions asked.
How is hieu.asia different from other fortune-telling apps?
Three things: (1) Tử Vi and Bát Tự are calculated using the Northern-school method with 114 stars — not pulled from a lookup table; (2) the AI Mentor holds a real, contextual conversation, not a scripted chatbot; (3) the tone stays calm and non-deterministic — you're always the one who decides.
