1. About this policy
Neurobyte operates HSC ICT+, a study app for Bangladeshi HSC students. Core study tools, books and practice are available without creating an account.
2. Information we handle and why
- Google sign-in: Firebase Authentication identifies your app account using your Google account identifier and provides your name, email and Google profile photo, when available. The photo can appear in your profile and in an ICT Battle room you join.
- Student profile: After sign-in, we ask for your name, phone number, college and district to set up your profile. The phone number is for account support and recovery verification. We do not use it for marketing. An optional custom photo is compressed on your device and saved with your profile in Cloud Firestore. Profile information is also cached on your device so it can load offline. A copy of your name, phone number, college, district, email and whether you added a photo is also kept on the Neurobyte server so our team can support students; it is removed when you delete your account. If our server is offline at that moment, your Firebase account is still deleted and the app removes the server copy the next time it can reach our server.
- ICT Battle: When you create or join a room, our server uses your display name, your custom profile photo or available Google photo link, room and session details, and answers to run the match. The server temporarily uses the connection IP to limit repeated room requests. Other players in the room can see your display name and photo. A custom photo is kept in server memory only while the room exists, for up to 15 minutes, and is not stored on disk. Recent match history is saved on your device.
- Question reports: When you send feedback on a question, the app can store the question, reason, comment and report time locally and send them to the Neurobyte server for review by our team. If you are signed in, the app sends a sign-in token that the server checks, and the report stores your account ID, name and email. Reports queued offline may be sent later.
- Notifications: Firebase Cloud Messaging uses an app installation token to deliver push notices. Notification permission is managed in Android settings. Study reminders are scheduled locally on your phone. Older app versions may have a linked Battle invitation registration.
- Local study data: Study notes, practice activity and app preferences can be stored on your device.
3. Service providers and external links
We use Google Sign-In, Firebase Authentication, Cloud Firestore and Firebase Cloud Messaging to provide the features above. Neurobyte operates the live Battle server. See Google's Privacy Policy for information about its services.
HSC ICT+ can show announcements about Neurobyte classes. Tapping the class contact button opens WhatsApp with a draft message for you to review and send. WhatsApp handles any message you choose to send under its own privacy policy. HSC ICT+ does not use a third-party ad network or the Android Advertising ID for these announcements.
4. Retention and deletion
We keep your account and saved profile until you delete the account or we process a verified deletion request. ICT Battle room data is held temporarily in server memory. Unused rooms expire after 15 minutes. Active rooms expire after the match deadline, with up to 15 extra minutes for results. Expired rooms are removed during server cleanup. Local notes, activity and preferences remain on the device until you remove them or clear the app's storage.
To delete your account, open Student Profile, select the account deletion option, and confirm your Google account. The app deletes the Firebase sign-in record, saved profile and photo, and any linked legacy Battle invitation registration. On the device where you delete the account, it also clears the saved profile cache and Battle history. General push notices are tied to the app installation and can still be managed in Android settings after account deletion.
Question reports are kept for reviewing and correcting questions. To request removal of personal information from a report or delete an account without the app, use the Account Deletion page. We verify account ownership before processing requests.
5. Children's Privacy
Our app is designed for students in grades 11 and 12 (typically 16–19 years of age). We do not knowingly collect information from children under 13. If any parent or guardian becomes aware that their child under 13 provided personal information, please contact us immediately.
6. Independent Educational Disclaimer
HSC ICT+ is an independent digital study aid created by Neurobyte. It is not endorsed by or affiliated with the National Curriculum and Textbook Board (NCTB) or the Ministry of Education, Bangladesh.
