Frequently Asked Questions
Is RollBook really 100% offline?
Yes. RollBook stores all subjects, timetables, and logs directly in your device's internal storage database. You can track attendance seamlessly without an internet connection or cellular data.
How does the 75% target calculator work?
RollBook automatically tracks your overall percentage and calculates exactly how many consecutive classes you need to attend to satisfy the standard 75% attendance threshold. If your attendance slips below the threshold, it flags the class with an immediate "At risk" badge.
How do I back up my attendance records?
Under Backup & Restore in settings, you can export a full .bak database archive to your device downloads or connect your Google Drive account for automatic secure cloud backups.
