Privacy Policy
1. Introduction
Welcome to Calc Studio Hub. We develop utility, educational, and study apps for Android devices (including study guides, flashcard tools, calculators, and reference applications).
Your privacy is extremely important to us. This Privacy Policy explains our commitment to protecting your privacy when you use any application published by Calc Studio Hub on the Google Play Store.
2. Information Collection and Use
A. No Personal Data Collection
Our applications do NOT require user registration, account creation, or login. We do NOT collect, transmit, store, or sell any personally identifiable information (PII) such as your name, email address, phone number, physical address, precise location, or contact list.
B. Local On-Device Data Storage
Our apps are designed to work locally on your device. Any data generated while using our apps—such as quiz progress, score history, flashcard bookmarks, timer settings, or theme preferences—is stored 100% locally on your device. This information never leaves your device and is never transmitted to us or any third party.
C. No Analytics or Advertising Frameworks
No Advertisements: Our apps do not contain third-party advertisements or ad networks. We do not use advertising identifiers (like Google Advertising ID) to track you.
No Analytics: We do not embed third-party tracking scripts, behavioral analytics, or profiling frameworks.
3. Internet Access & Network Usage
Most of our applications operate completely offline. In cases where an app may offer optional external links (such as directing you to the Google Play Store to rate the app or view developer details), opening those links is entirely optional and subject to the privacy policies of those external services.
4. Children’s Privacy (COPPA Compliance)
Our applications do not collect any personal information from anyone, including children under the age of 13. Because our apps contain no ads, no tracking, and no data collection, they are fully safe for users of all ages.
5. Security
Because all user data (such as app progress and preferences) remains strictly on your local device, your data security is inherently protected by your Android device's built-in operating system security.
Uninstalling the application will permanently remove all locally saved app progress from your device.
6. Changes to This Privacy Policy
We may update our Privacy Policy from time to time to reflect updates to our applications or legal requirements.
