Information We Collect

We do not collect any personal information. Our apps work entirely offline and do not require account creation, name, email, phone number, or any other personal data.

Data Storage

Any data entered into our apps (loan amounts, appliance lists, tax figures) is stored locally on your device only. This data is never transmitted to our servers or any third party.

Analytics & Advertising

Our apps do not display advertisements. We do not use Google AdMob, Facebook Audience Network, or any advertising SDK. We do not use analytics tools that collect user behaviour data.

Children’s Privacy (COPPA)

Several apps are designed for children under 13 (Learn & Identify, ABC Kids, 123 Numbers, Math Kids, Phonics & Spelling, Shapes & Colors, Jigsaw Puzzles). We are fully COPPA-compliant. These apps collect no personal information from children. No behavioural advertising or third-party analytics are used in children’s apps.

Permissions

Our apps request only minimum permissions necessary. Most require no permissions at all. Where storage permission is requested, it is used only for saving locally generated reports to your device — never for accessing personal files.

Third-Party Services

Our apps do not integrate with third-party SDKs for advertising, analytics, social media, or crash reporting. The only third-party integration is Google Play Services (required by Android), governed by Google’s own privacy policy.
