Privacy Policy

This app does not require sign-in and does not collect, store, or transmit any personal information.

• All user data — trips, expenses, photos, rate alerts — is stored only on your device.
• Nothing is sent to remote servers or stored in the cloud.
• No accounts, no email/name/photo collection, no identity database.

External communication is limited to the cases below. None of these include personally identifiable information.

• Exchange rates — Anonymous fetch from ExchangeRate-API.
• Advertising — Google AdMob (app) / AdSense (web) when ads are enabled. See section 7.
• Subscription — Communicates with Google Play Billing for the ad-removal subscription (₩990/month) checkout, renewal, and cancellation. The app only receives subscription status, not card details.

None.

We collect no personally identifiable information. No email, name, phone number, location, or contacts. We do not operate a user database.

The following stays on your device only:

• Trip information (name, dates, currency)
• Expenses (amount, category, memo, location, photos)
• Rate alert preferences
• App settings (dark mode, language, base currency)

Uninstalling the app deletes all of the above. There is no remote backup.

The in-app backup feature lets you export your data as a ZIP file and share it wherever you choose (e.g. KakaoTalk, Google Drive). The app and developer never upload it automatically.

• ExchangeRate-API — Currency rates (anonymous)
• Google AdMob — Mobile app ads (skipped after ad-removal purchase)
• Google AdSense — Web ads
• Google Play Billing — In-app purchase only when buying ad removal
• Vercel — Web page hosting

When ads are enabled, Google AdMob/AdSense may collect the advertising ID, device info, and usage data to serve ads. The ad-removal subscription (₩990/month) removes all banner/interstitial ads and stops the ad-related data collection while active. You can cancel anytime.

See Google Privacy Policy for details.

Because we do not collect personal information, traditional access/edit/delete requests do not apply.

• Delete all data: uninstall the app — everything is gone.
• Export data: use the in-app backup to create a ZIP.
• Reset advertising ID: Android Settings → Privacy → Ads → Reset advertising ID.

The app does not knowingly collect data from children under 14. Since we collect no identifying information, individual children cannot be identified. To minimize ad ID exposure, consider buying the ad removal IAP or limiting the device ad ID.

We may update this policy as laws or features change. Updates are posted on this page.
