Terms of Use

Last updated: 2026-05-20

Informational tool only — travel safely

HiddenGem aggregates the Tourism OpenAPI (data.go.kr) open data to suggest low-crowd tourist spots and shows estimated crowd indicators. Real on-site conditions may differ from what the app shows. Crowd estimates are derived from public big-data feeds released with a delay (typically about a month). Visiting hours, parking, and accessibility information come from the Tourism OpenAPI (data.go.kr) and may be out of date. HiddenGem and its author are not liable for travel decisions, accidents, delays, fees, or any other consequence of relying on the information shown.

Data accuracy and availability

Catalog, capacity, image, and event data come from Tourism OpenAPI 4.0 (data.go.kr) (KorService2 / EngService2 / ChsService2 / JpnService2). Region-level visitor statistics come from the DataLabService big-data API. KakaoMap renders map tiles. Any of these upstream feeds can be intermittently unavailable, delayed, partially updated, or removed. HiddenGem does not control these feeds and does not guarantee accuracy, completeness, or availability.

Acceptable use

• Use HiddenGem to plan your own personal travel.
• Do not bulk-scrape, redistribute, or re-host TourAPI / DataLabService data through the app.
• Do not circumvent or abuse the Tourism OpenAPI service key, Kakao app key, or Supabase rate limits.
• When uploading community discoveries, do not upload illegal content, sexual content, hate speech, personally identifying photos of strangers, or copyrighted material you do not have rights to.
• Three user reports auto-hide a community post; repeated violations may result in account suspension or removal.

Sign-in and accounts

HiddenGem supports Sign in with Apple, Google Sign-In, email magic-link, and Kakao Login. You authenticate with the provider you choose; HiddenGem receives only the identifiers that provider shares. You are responsible for the security of your provider account. You can delete your HiddenGem account in Settings; we will revoke third-party tokens where the provider supports it and finish permanent deletion within 30 days (see Privacy Policy).

Pricing

HiddenGem is free at launch. If a paid tier is added later, these terms will be updated with the relevant subscription details before any charges occur.

Privacy Policy

Your use of HiddenGem is also governed by our Privacy Policy.

Termination

You can delete your account inside the app at any time, or uninstall the app to stop using the service. We may suspend or terminate accounts that violate these terms.

Changes to these terms

We may update these terms over time. The "Last updated" date at the top reflects the current version. The app records the version you accepted; if the version changes after a release, you will be asked to re-consent on next launch.

Governing law

These terms are governed by the laws of the Republic of Korea, without regard to conflict-of-law principles. Apple's standard EULA also applies to your use of the app as a licensed application from the App Store.
