Privacy Policy

Last updated: July 17, 2026

1. Introduction

Korutech.io ("we," "our," or "us") operates the Quick Currency Converter mobile application (the "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Service.

GDPR Compliance Notice: This app is designed with privacy-conscious defaults. We do not require an account, and we limit collection to data used for app functionality, reliability, subscriptions, analytics, and advertising in the free version.

This diagnostic data helps us identify and fix issues that affect app stability, performance, and security.

2.4 Third-Party Data Collection

Premium Subscription Privacy: Active Premium subscribers do not see in-app ads, and the app skips in-app advertising initialization for premium access. Limited analytics, crash reporting, purchase processing, and support-related processing may still occur.

3.1 Premium vs Free Version Data Usage

We implement appropriate technical and organizational measures to protect your personal data:

8. International Data Transfers

Your data may be transferred to and processed in countries outside your country of residence. We ensure appropriate safeguards are in place for such transfers, including:

9. Children's Privacy

Our Service is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately.

10. Third-Party Services

10.1 Google Mobile Ads (Free Version Only)

We use Google Mobile Ads to display advertisements in the free version of our app. Google may process advertising identifiers, device identifiers, app activity, diagnostics, and approximate location signals as described in Google's policies and depending on your device settings, region, consent choices, and platform permissions. On iOS, we request tracking permission where required before personalized advertising. In some regions, the app uses non-personalized ads. Premium subscribers do not see in-app ads while premium access is active.

10.2 Google Analytics 4 and Korutech Analytics Backend

The app sends limited usage events to a Korutech analytics backend using the app-generated identifier described above. These events may be forwarded to Google Analytics 4 when configured. We use this data to understand app usage patterns, troubleshoot issues, and improve the product. The website also uses Google Analytics to measure website visits and performance.

10.3 Sentry (Crash Reporting)

We use Sentry for crash reporting and performance monitoring to improve app stability and user experience:

Note: Sentry is configured with default personal information collection disabled. We filter sensitive breadcrumb text before sending crash reports, but crash data can still include technical context needed for debugging.

10.4 RevenueCat

We use RevenueCat for in-app purchase management. RevenueCat processes purchase history, subscription status, product identifiers, and store receipt information according to their privacy policy so that Premium access can be granted and restored.

10.5 Exchange Rate API

We use ExchangeRate-API.com and the Korutech backend to fetch current currency rates. Rate requests may include the requested base currency and the app-generated identifier described above so the service can provide rates, monitor reliability, and troubleshoot issues. This service does not need your account information.

11. Data Controller and Processor

Korutech.io acts as the data controller for the personal data collected through the Quick Currency Converter app. For third-party services, we act as a data processor, and those services act as data controllers for their respective data collection.

12. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy in the app and updating the "Last updated" date. Changes are effective immediately upon posting.
