Privacy Policy
Effective date: October 28, 2026
TodaySpend - Expense Tracker (“the app”, called 오늘지출 in Korean) has no sign-up and no servers run by the developer. Your expense records are stored only on your device and are never sent to the developer. The app does use the outside services listed below for ads and purchases, and those services process some information.
1. Information stored only on your device
- Expense amounts, dates, categories, payment methods, notes, budgets, recurring expenses and app settings
The developer cannot see this information, and it is deleted when you delete the app. Backup files you create with the Backup feature are saved wherever you choose (the Files app, a messenger and so on), and you are responsible for them after that.
2. Information processed by outside services
| Service | Purpose | Information processed |
|---|---|---|
| Google AdMob (Google) |
Showing a banner ad at the bottom of the screen to free users | Device information (model, operating system), IP address, advertising identifier, ad impressions and clicks |
| RevenueCat | Confirming and restoring TodaySpend Pro purchases | An anonymous user ID created by the app, purchase history (product, purchase time, store receipt), device information |
| App Store / Google Play | Payments | Each store handles payment itself. The app and the developer never receive card numbers or other payment details. |
The app does not request personalized ads (only non-personalized ads are shown) and does not track you across other companies’ apps or websites. Once you buy Pro, ads are no longer shown and no information is sent to AdMob. Each service handles information under its own privacy policy: Google, RevenueCat.
3. Device permissions
- Notifications: used only if you turn on the daily reminder. Reminders are scheduled on your device.
- Face ID / fingerprint: used only if you turn on App Lock. The app only learns whether authentication succeeded and never accesses biometric data.
- File picker: when restoring a backup, the app reads only the one file you choose.
Permissions are requested only when needed, and you can turn them off at any time in your device settings.
4. Retention and deletion
Information on your device is deleted when you delete the app, and you can delete any expense in the app at any time. Information processed by outside services is kept according to each company’s policy. To ask for your purchase record at RevenueCat to be deleted, contact us at the address below.
5. Sharing and sale
The developer does not sell your information or share it with anyone other than the services listed in section 2.
6. Children
The app is not directed to children under 13 (under 14 in Korea).
