Exam Countdown & Study Planner (accessible at examstudyplanner.com and available on Android & Windows) is developed and operated by LazyByte Labs (lazybyte.in), founded by PhD Research Scholar Ikramul Hossain Mondal.
Our mission is to empower high school, university, and competitive exam students with distraction-free, syllabus-aligned study management tools. We operate with complete transparency regarding data processing, privacy, and intellectual property.
📌
Official App Privacy Policy Notice: The official, master Privacy Policy governing the
Android, iOS, and Windows applications is hosted on our brand website. Users and store reviewers should refer to the official brand policy and any legal updates directly at
https://lazybyte.in/privacy-policy/exam-countdown--study-planner.
We follow the principle of strict data minimization. We only collect or process information necessary to deliver core application functionality and ensure system reliability:
- ✓
Local Study Data (Stored on Device): Your exam subjects, countdown dates, syllabus chapter lists, Pomodoro focus logs, and daily to-do lists are saved locally in your device's internal database (e.g., SQLite or LocalStorage).
- ✓
Account Information (Optional Cloud Sync): If you choose to enable cloud sync across devices, we collect your email address and authentication credentials via secure Firebase/Google Auth authentication protocols.
- ✓
Aggregate Operational Analytics: We process anonymized operational metrics (app crash reports, device OS version, and page load diagnostics) to optimize app stability across Android and Windows platforms.
- ✓
Support Communications: When you email us directly at
support@lazybyte.in, we retain your email and query history solely to respond to your technical request.
Your data is processed strictly to serve your academic preparation goals:
- ✓
Calculating remaining study days and syllabus progress completion percentages.
- ✓
Synchronizing your exam countdowns and revision schedules seamlessly between your Android phone and Windows desktop when logged into cloud sync.
- ✓
Generating AI study schedules and quiz questions when requested via the Diya AI Study Assistant.
We hold a firm commitment to maintaining a safe, distraction-free environment for students:
- ✕
No Selling or Renting Data: We do NOT sell, rent, trade, or monetize your personal details or study records with any third-party advertisers or data brokers.
- ✕
No Intrusive Ad Telemetry: We do not run third-party advertising SDKs or invasive cross-site behavioral tracking scripts.
- ✕
No Unsolicited Spam: We will never send marketing spam or sell your email address to mailing list aggregators.
Our premium optional features—Cloud Sync and Diya AI Assistant—are built with privacy-by-design principles:
☁️
Encrypted Cloud Sync: All multi-device sync data transmitted between your device and Google Cloud Firestore is encrypted in transit via SSL/TLS (HTTPS) and encrypted at rest using industry-standard AES-256 encryption.
🧠
Diya AI Processing: AI study prompts (such as requesting a custom revision schedule or generating chapter quizzes) are processed via secure API endpoints. Your study notes and AI queries are never used to train public foundation AI models.
We implement technical and organizational measures to safeguard your information against unauthorized access, alteration, or disclosure:
Local data is protected by standard OS sandboxing on Android and Windows. Remote cloud infrastructure is hosted on enterprise-grade Google Cloud Platform infrastructure featuring multi-layer firewalls, automatic security patching, and strict access controls.
Exam Countdown & Study Planner is designed for school, college, and university students preparing for exams. We comply with student privacy laws including the Indian Digital Personal Data Protection (DPDP) Act 2023 and the Children's Online Privacy Protection Act (COPPA).
We do not knowingly collect personal identifiable information from children under 13 without parental consent. If a parent or guardian becomes aware that a child has provided us with email credentials, please contact us for immediate data deletion.
You maintain full sovereignty over your data under global data protection laws:
- ✓
Right to Clear Local Data: You can clear all local app data anytime via the app's settings menu or your device's application manager.
- ✓
Right to Account Deletion: You can delete your cloud sync account and remove all server-side Firestore records directly from inside the app's Account tab or by emailing support.
- ✓
Right of Access & Export: You may request a copy of any personal data linked to your sync account by contacting
support@lazybyte.in.
We may periodically update this Privacy Policy to reflect app feature enhancements, infrastructure updates, or evolving statutory compliance requirements. The latest version will always be published on this page with an updated timestamp.
