BITNA Terms of Service

Effective 2026-11-10 · DYQ (Daeyeon Won)

1. The service

BITNA analyzes your personal color from a photo and lets you preview hair, clothes and accessories with AI, for reference. Analysis and color previews run on your phone; AI images are made only when you tap to create them.

2. Eligibility

• You must be 16 or older.
• You agree to these terms and the Privacy Policy when you first open the app.

3. What you must not do

• Use only photos of yourself, or of people who have agreed. Do not use other people's photos without permission.
• Do not try to create nude, sexual, demeaning or deceptive images. Such requests are refused.
• Do not present AI images as real photos to mislead others, or infringe anyone's portrait rights or copyright.
• Abnormal heavy use or obtaining credits fraudulently may lead to restrictions.

4. AI images

• AI images are reference previews of how something might look. Real salon results, colors and sizes can differ.
• AI images are labeled "AI-generated". Images you share outside the app carry a small "AI-generated · BITNA" mark and AI-generated file metadata. If a result is broken (odd body or face, or someone else's face), report it in the app and we refund that credit (once a day, up to 3 times a year).
• You may use the AI images you create freely for personal purposes.

5. AI credits

• Welcome and bonus credits (card sharing, friend invites) are free; amounts may change.
• Paid credits are sold only through Google Play billing. There is no automatic renewal.
• Paid credits can be used for 5 years from purchase.
• Refunds: within 7 days of purchase, if no purchased credits were used, you can get a full refund. If some were used, you can request a refund for the unused credits. Free credits are not refundable.
• Detailed color report: no separate payment; it opens with AI credits (the number shown in the app, currently 1), including one AI drape photo of your face. Once opened it stays open, and the credits used are not returned. You can see a preview (some colors) before opening; if it fails to open, no credits are used. Reports bought earlier (2,900 KRW) stay available, and we refund them if they do not open or differ from the description.
• Request refunds through Google Play or by email (support@designyourquality.com).

6. Changes and termination

We may change or stop features and will announce important changes in advance in the app and on this page. If the service ends while you hold paid credits, we refund the unused credits.

7. Liability

Except for intent or gross negligence, BITNA is not responsible for decisions (salon work, purchases) made based on AI previews. Shops linked from the app are responsible for their products and delivery.
