2. Privacy Policy (개인정보처리방침)

What we collect

Account: your email address (used as account identity and for service contact). No password is stored — access is via API key.
Your indexed images: when you index a folder, only downscaled thumbnails (≤256px) and derived data (captions, embedding vectors, file names/paths as text) are sent and stored. Original image files never leave your machine. Indexing only happens for folders you explicitly select — HyeAn does not scan your project or disk on its own.
Usage records: API calls (e.g., match/index counts, timestamps) for quota, billing and abuse prevention.
Site analytics: the landing page uses Google Analytics (cookies) to measure visits; our own server-side counters use no cookies and store no raw IP addresses (only a short non-reversible hash and country code).

What we do NOT do

We do not sell or share your data with third parties for advertising.
We do not train AI models on your indexed images.
We do not store your original image files.

Payments

Card payments are processed by our merchant of record (Lemon Squeezy); we never see or store card numbers.

Deletion & retention

You can remove indexed items at any time from the app (index management), and request full account/data deletion by emailing admin@14dimension.com from your signup address. Backups are purged on a rolling basis.

3. Terms of Service (이용약관)

HyeAn is provided "as is". We aim for high availability but do not guarantee uninterrupted service; matching results are AI-generated suggestions and may be imperfect.
You must own or have rights to the images you index. Illegal content and abuse (including attempts to index content you have no rights to, or abnormal automated bulk traffic) may result in suspension.
Paid plans are month/year subscriptions handled by our payment processor; you can cancel anytime and keep access until the end of the paid period. Refunds follow the processor's consumer policy and applicable Korean e-commerce law (전자상거래법).
Free-tier quotas and fair-use limits may be adjusted with notice on this site.
These terms are governed by the laws of the Republic of Korea.
