Privacy Policy ​

Last Updated: August 31, 2026

Welcome to Flügel Mathematics, an open academic initiative and educational treatise developed by Flügelsoft Labs ("we", "our", or "us"). We are committed to protecting your privacy and ensuring transparency regarding any data collected through our website, web application, and mobile applications (Android and iOS).

1. Information We Collect ​

A. Information You Voluntarily Provide ​

  • Inquiries & Academic Submissions: When you reach out to our editorial team via our Contact Form or direct email (mathematics@flugelsoft.com), we collect your name, email address, academic subject/role, and message content to respond to your queries, errata submissions, or collaboration requests.
  • Problem Set & Practice Inputs: Your interactive practice responses, drill toggles, and formula tracker selections are processed locally in your browser/device session storage and are not transmitted to external commercial databases.

B. Automatically Collected Technical Data ​

  • Device & Usage Diagnostics: To maintain optimal uptime, performance, and responsive layout across different screen sizes, standard web server logs may record your browser type, device operating system, approximate geographic region (country/city level), referring URL, and page request timestamps.
  • Crash Reports & Performance Metrics: Our mobile applications may record anonymous diagnostic stack traces in the event of unexpected application termination to improve stability.

2. How We Use Your Information ​

We use collected information exclusively to:

  1. Deliver and render academic mathematics content, interactive simulations, and formula cheat sheets.
  2. Respond to academic peer-reviews, error corrections, and user inquiries.
  3. Optimize mobile application performance, navigation responsiveness, and offline caching.
  4. Safeguard our platform against automated abusive requests and malicious traffic.

We never sell, rent, monetize, or trade your personal information to third-party advertisers or data brokers.

3. Cookies & Local Storage ​

  • Session & Theme Preferences: We use lightweight browser localStorage to preserve your UI preferences (such as Dark/Light theme mode and mobile navigation states).
  • No Third-Party Advertising Cookies: Flügel Mathematics contains zero third-party commercial tracking or behavioural advertising pixels.

4. Mobile Application Permissions (Android & iOS) ​

Our Android (com.flugelsoft.mathematics) and iOS applications are engineered for lightweight, distraction-free mathematical study:

  • Network Access: Required to fetch online asset updates and submit editorial messages via the contact API.
  • Local Storage Access: Used solely to cache offline study guides, formula cards, and interactive diagrams.
  • No Invasive Permissions: We do not request or access your device location, contacts, microphone, camera, or personal photo library.

5. Data Security & Retention ​

We employ industry-standard transport layer security (HTTPS/TLS) encryption for all transmitted communications. Editorial communications and contact records are retained only as long as necessary to resolve inquiries and ensure editorial accuracy.

6. Children's Online Privacy Protection ​

Flügel Mathematics provides academic curriculum suitable for high school, college, and Olympiad students. We do not knowingly collect personally identifiable information from children under the age of 13. If you believe a minor has submitted personal information without parental consent, please contact us immediately for prompt deletion.

7. Changes to This Privacy Policy ​

We may periodically update this policy to reflect enhancements in curriculum features, regulatory requirements, or mobile app releases. Changes will be posted on this page with an updated revision date.
