1. Executive Privacy Commitment
Code Calendar is an open-source Android utility engineered for competitive programmers. We operate on a strict Zero-Knowledge and Zero-Harvesting privacy policy. We do not collect, sell, or transmit any personally identifiable information, browsing history, or coding profile credentials.
2. 100% On-Device Room Database Storage
All bookmarking data, contest reminders, user handle queries, cache entries, and heatmaps are stored locally on your device in a sandboxed SQLite/Room Database. The application does not maintain any remote user accounts, databases, or cloud profiling servers.
3. Interaction with Public Contest APIs
Code Calendar queries publicly accessible, read-only API endpoints (LeetCode, Codeforces, CodeChef, AtCoder) to retrieve contest schedules and public user rankings. These network requests are performed over encrypted HTTPS/TLS 1.3 connections. No private tokens or session secrets are ever collected or required.
4. Package Visibility & Android 10/11+ Compatibility Disclosures
To provide seamless developer ergonomics, Code Calendar resolves device intents to open contest links directly in installed apps (e.g. GitHub, LeetCode client, web browser) or export schedules directly into native Calendar apps.
• Android 10 (API 29) & Below: Package visibility is provided natively by the Android OS to resolve installed activity intents.
• Android 11+ (API 30+): Package visibility is strictly constrained using explicit <queries> elements declared in the Android Manifest.
Guarantee: The app never inventories, stores, logs, or transmits your installed applications list. All intent checks execute strictly on-device in volatile runtime memory.
5. Zero Third-Party Advertising & Telemetry SDKs
Code Calendar is completely free of third-party advertising SDKs, tracking pixels, and behavioral telemetry frameworks. Your schedule planning and rating analysis remain completely confidential to your personal device.
6. Google Play Developer Policy Compliance
This application complies strictly with Google Play Developer Program Policies, including the User Data Policy, Permissions Policy, and Exact Alarm Guidelines. All permission requests are explicitly justified by core application features.
7. User Data Deletion & Account Erasure Policy
Under Google Play Data Safety requirements and global privacy standards (GDPR / CCPA), users have the right to permanent deletion of all stored data:
1. Instant On-Device Deletion: Navigate to Android Settings > Apps > Code Calendar > Storage & Cache > Clear Data. This immediately and permanently deletes all local Room databases, cached profiles, and alarms.
2. Cloud Profile Erasure: If you have synced handles or cloud streak data, you can request immediate server-side deletion anytime via our dedicated online Data Deletion Portal (https://vishalbhutekar.netlify.app/myapps/codecalendar/delete-account) or by emailing the developer. All matching records are purged within 24 to 48 hours.
8. Developer Inquiries & Source Audit
For any legal inquiries, security disclosures, or questions regarding this Privacy Policy, please contact developer Vishal Bhutekar directly at vishal.bhutekar1@gmail.com or inspect the source repository on GitHub.
