# Privacy Policy
**App name:** Financial Calculator (금융계산기)
**Effective date:** August 10, 2026
This Privacy Policy describes how the Financial Calculator application ("the App", "we", "us", or "our") handles information when you use it. By downloading or using the App, you agree to the practices described in this policy.
## 1. Information We Collect
The App itself does not require you to create an account and does not ask you to provide personal information such as your name, email address, or phone number. Calculations you perform in the App are not stored on our servers.
However, the App uses third-party services that may collect certain information automatically:
- **Device and usage information** — such as device model, operating system version, language, app version, crashes, and how you interact with the App.
- **Advertising identifiers** — such as the Google Advertising ID (AAID), used to serve and measure advertising.
- **Approximate location** — some advertising services may infer approximate location from your IP address to deliver relevant ads.
We do not collect or store this information on our own servers. It is processed by the third-party services listed below.
## 2. Web Content
The App displays its calculator screens by loading web pages from our web server. Like most web servers, it may automatically record standard technical information in server logs, such as your IP address, request time, and browser/user-agent string. This information is used only to operate and maintain the service and is not linked to your identity.
## 3. Third-Party Services
The App uses the following third-party services, each of which has its own privacy policy:
- **Google AdMob** (advertising)
https://policies.google.com/technologies/ads
- **Google Firebase Analytics** (usage analytics)
https://firebase.google.com/support/privacy
- **Google Play Services**
https://policies.google.com/privacy
These services may collect and process data as described in their respective privacy policies.
## 4. How the Information Is Used
Information collected through the services above is used to:
- Display advertisements, including personalized or non-personalized ads;
- Measure advertising performance;
- Understand how the App is used so we can improve it;
- Diagnose crashes and technical problems;
- Maintain the security and proper functioning of the App.
## 5. Advertising
The App displays banner and interstitial ads served by Google AdMob. AdMob may use advertising identifiers to show personalized ads. You can control ad personalization and reset or delete your advertising ID in your device settings:
- **Android:** Settings → Google → Ads
For more information about how Google uses data from apps that use its services, see:

## 6. Children's Privacy
The App is not directed at children under the age of 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided personal information through the App, please contact us so we can take appropriate action.
## 7. Data Retention
We do not retain personal data on our own servers beyond standard, short-term server logs described in Section 2. Any data processed by the third-party services listed above is retained according to their respective data retention policies.
## 8. Your Rights
Depending on your location, you may have rights regarding your personal data, such as the right to access, correct, or delete it, or to object to certain processing. Because the relevant data is handled by the third-party services listed above, you may exercise these rights directly through those services, or contact us for assistance.
## 9. Security
We rely on the security measures provided by the third-party services and platforms used by the App. However, no method of electronic transmission or storage is completely secure, and we cannot guarantee absolute security.
## 10. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated effective date. Your continued use of the App after changes are posted constitutes your acceptance of the revised policy.
