Frequently Asked Questions

Everything you need to know about Foliq’s ledger precision and offline architecture.

No! Foliq is designed from the ground up as an offline-first application. All your transactions, contacts, balances, and reports are saved directly on your Android device's secured local database. You can use Foliq anywhere without internet connectivity.

The `.foliq` format is our custom tamper-proof binary container format. It compresses your data using GZIP and encrypts it with AES-256-GCM authenticated encryption. Opening the file in a text editor reveals only scrambled binary bytes, ensuring your financial privacy is completely protected when shared or stored.

Yes, absolutely! Foliq features 100% backward compatibility. When inspecting a file to restore, Foliq automatically detects whether it is a `.foliq` binary container or a legacy `.json` backup file and restores your ledger seamlessly.

Traditional apps use floating-point numbers (`Float` or `Double`), which introduce rounding drifts (e.g., `0.1 + 0.2 = 0.30000000000000004`). Foliq calculates every transaction amount in minor currency units (such as paisa or cents) using strict 64-bit integer arithmetic (`Long`), guaranteeing mathematical determinism.

No. Foliq never accesses or uploads your contact list to a cloud server. When you tap "Remind" on a customer's Khata, Foliq simply constructs a pre-formatted message link and opens your device's WhatsApp app with your approval.
