Privacy Policy

1. Information we collect and why

Email address: used only to send login codes and identify your account.

Content you create: trip plans, conquest records, album photos, favorite works, new-spot notification settings and spots you submit. Used only to provide the features of the service.

Access logs: our service providers (Vercel, Supabase) keep IP addresses, access times and similar data for a limited period for security and incident response.

We do not collect location data or the location metadata in photos (EXIF). Photos are re-rendered on your device before upload, which removes location data.

2. Retention and deletion

We keep your data until you delete your account. When you do, your account, records and photos are deleted immediately. Spots you submitted remain as public information, but the link to you is removed.

You can delete album photos at any time.

Deletion procedure and method: when the retention period ends or you delete your account, the data is destroyed without delay. Electronic files are permanently erased so they cannot be recovered. We do not create paper records.

3. Sharing with third parties

We do not share or sell personal data to third parties, except where required by law.

4. Processors and international transfers

We entrust processing to the providers below, all of which are located outside Korea. The timing and method of transfer are the same for all: network transmission over the internet each time you use the service.

Supabase, Inc. — Data transferred: email address, content and photos you create · Destination: data is stored in Seoul, Korea (AWS); administrative access may occur from the United States · Recipient contact: privacy@supabase.com · Purpose: database, login and photo storage · Retention: until you delete your account (destroyed immediately on deletion)

Vercel Inc. — Data transferred: IP address, access time, request details · Destination: United States (requests pass through the nearest Vercel server) · Recipient contact: privacy@vercel.com · Purpose: web hosting, security and incident response · Retention: access logs are deleted automatically after Vercel's retention period

Resend — Data transferred: email address, body of the login code email · Destination: United States · Recipient contact: support@resend.com · Purpose: sending login code emails · Retention: delivery logs are deleted automatically after Resend's retention period

Cloudflare, Inc. — Data transferred: IP address, browser information (bot detection), map file requests · Destination: United States (requests pass through the nearest Cloudflare server) · Recipient contact: privacyquestions@cloudflare.com · Purpose: blocking automated sign-ups at login (Turnstile), serving map files · Retention: deleted automatically after Cloudflare's retention period

Spot descriptions are translated with AI (Anthropic via Vercel AI Gateway), but no personal data is sent.

How to refuse and what happens: if you do not want your data transferred abroad, contact us at the address below or delete your account. Without these providers, however, login, storage, email delivery and maps do not work, so the service cannot be used.

5. Security measures

Data in transit is encrypted with HTTPS.

The database uses row-level security (RLS), so only you can read and write your own records.

We do not store passwords. Login uses only a one-time 6-digit code sent by email.

Administrator access is limited to the minimum staff needed to run the service, and server keys are kept only in server environment variables.

6. Cookies and on-device storage

We store on this device a cookie to keep you logged in, a cache of your trip screens for offline use, conquest records that could not be sent yet and favorites chosen before login. We do not use advertising or tracking cookies.

How to refuse cookies: you can block or delete cookies in your browser settings. If you do, you will not stay logged in and cannot use features that require login.

7. Your rights

In the Me tab you can view and delete your records or delete your account. To request access, correction, deletion or suspension of processing, contact us at the address below.

Users under 14 may not sign up.

9. Changes

If we change this policy, we will announce it in the service at least 7 days before it takes effect.
