Welcome to BolNepali. We are committed to protecting the privacy, security, and digital dignity of all our learners. This Privacy Policy explains transparently how our application collects, uses, protects, and handles your information across our web platform and Progressive Web App (PWA).
1. Information We Collect
- Account Information: When you create an optional cloud account for cross-device sync, we collect your chosen name, mobile number, and a securely salted SHA-256 cryptographic password hash. We never store plain text passwords.
- Learning Progress Data: XP points, daily streak counts, completed lessons, learned words count, active lesson level/day, and starred vocabulary words.
- Feedback & Word Suggestions: Messages, ratings, and requested Nepali words submitted through our feedback portal.
2. Microphone & Pronunciation Recognition
BolNepali requests microphone access exclusively when you tap the 🎤 Speech button in daily lessons or the AI Voice Tutor.
3. Camera & Nepali Signboard Scanner
When you use the 📸 Signboard & Menu Scanner in the AI Suite, photos of Nepali signboards or restaurant menus are processed temporarily via secure API to extract text and generate Malayalam translations. Photos are not saved to our servers or used for marketing.
4. Cross-Device Cloud Sync & Storage
For registered learners, progress is synced securely to Google Cloud Firebase Firestore so you can start a lesson on your mobile phone and seamlessly continue on your PC/laptop. For guest learners, progress remains 100% local on your device inside browser LocalStorage.
5. Google AdSense & Third-Party Advertising
We use Google AdSense to serve non-intrusive advertisements to keep our language education free and accessible.
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads based on visits to BolNepali and/or other sites on the Internet.
- Learners may opt out of personalized advertising by visiting Google Ads Settings or aboutads.info.
6. PWA Service Worker & Offline Storage
Our Progressive Web App (PWA) uses a Service Worker to cache essential assets, including the complete Travel Survival phrasebook and audio synthesize engines. No sensitive personal data is leaked during offline caching.
7. Security Standards & Data Protection
We implement strict security measures including sliding-window API rate limiting to block automated brute-force attacks, timing-safe cryptographic comparisons (`timingSafeCompare`), input sanitization to eliminate Cross-Site Scripting (XSS), and HTTPS Transport Layer Security (HSTS).
8. User Rights & Data Control
You have full autonomy over your data. You may at any time log out from your profile, clear your local browser learning history, or request full account deletion by submitting a request through our in-app feedback modal or contacting support.
