Privacy Policy

Last updated: September 3, 2026

Kumpu App ("we", "us", or "our") operates mobile applications to serve users securely and transparently. This Privacy Policy outlines our data collection, usage, and protection practices across all our applications.

1. Information Collection and Local Processing

We do NOT collect, store, or transmit your personal data to external servers. All core operations take place strictly on your local device:

• General Data: We do not collect names, email addresses, phone numbers, location data, or account details on remote databases.
• Mortgage Loan Calc (Optional Inputs): Any borrower names, phone numbers, or repayment calculations entered into the app are used exclusively on your device to generate on-screen schedules and exported PDF reports. None of this data is transmitted off your device.
• PDF Export Feature: Generated PDF reports are saved directly to your local device storage. We do not access or store your generated files.

2. Children's Privacy (COPPA Compliance)

Our educational apps for children (such as Khmer Alphabet - Kids Version) strictly adhere to the Children's Online Privacy Protection Act (COPPA):

• No Tracking or Analytics: We do not collect analytics, track behavioral patterns, or collect persistent identifiers (like IMEI or Android ID). All progress and quiz scores remain on your local device.
• Parental Protection: Settings or external links are protected by parental gates to prevent accidental child interaction.

3. Local Device Permissions

Certain features request hardware access strictly for in-app processing:

• Microphone: Used for audio pronunciation practice in educational apps. Audio is processed locally and instantly discarded without being recorded or uploaded.
• Camera: Used exclusively for interactive educational activities. Photos are displayed locally and never saved or transmitted externally.
• Network Access: Required to stream audio (KangMeas FM) or check connectivity to serve advertisements (Mortgage Loan Calc).

4. Third-Party Services & Advertising

Our applications rely on standard Google services for features and monetization:

• Google Cast (KangMeas FM): Used to stream audio to compatible devices. Governed by Google's Privacy Policy.
• Google AdMob (Khmer Alphabet): Set to Child-Directed Treatment and restricted to 'G' (General Audience) rating. No interest-based or behavioral tracking is used for children.
• Google AdMob (Mortgage Loan Calc): Serves standard advertisements using device identifiers (e.g., Android Advertising ID).

5. Data Security

Because we do not transmit personal data or maintain external user databases, your information remains fully protected under your own device's security.

6. Changes to This Policy

We may update this policy periodically. Any changes will be published on this page with an updated revision date.
