Cloud Security & Backups

1. Hybrid Security Architecture

INLedger by Revenueer Solutions is engineered around a hybrid security model that delivers the unyielding reliability of local offline desktop billing alongside the automated disaster protection of real-time cloud sync.

Traditional cloud-only web applications force your billing counter to pause whenever internet speeds fluctuate. With INLedger, local transaction processing occurs directly on your PC hardware at microsecond speed, while background services automatically maintain your live cloud sync and disaster backups.

2. Local Storage Privacy & Data Isolation

Your day-to-day business accounting records are stored in a high-performance local SQLite database on your desktop computer:

• Zero External Keystroke Telemetry: Invoices, inventory counts, barcode scans, and party names are typed directly into local application memory.
• Hardware Isolation: Each terminal maintains its own local transaction journal, eliminating single-point cloud network failures.
• Customer Ledger Confidentiality: Your trade records are never shared, indexed, or analyzed by advertising trackers.

3. Automated Real-Time Cloud Sync & Backup

Cloud synchronization in INLedger is automated and real-time — it is neither an optional afterthought nor limited to simple manual backup copies:

• Delta Sync Technology: Only modified records (such as a new sales invoice or updated inventory balance) are transmitted, minimizing bandwidth consumption.
• Automatic Reconnection: If your network drops during a sale, your bill is printed immediately offline. When connectivity is restored, the queue syncs automatically without requiring user intervention.
• Single-Sync Reconciliation: Timestamped version tokens prevent data collision and ensure that bills raised at counter terminals sync accurately with administrative workstations.

4. Encryption Standards in Transit & At Rest

We deploy modern cryptographic standards across all synchronization pipelines:

• In-Transit Security: All API communication between the INLedger desktop application and our cloud sync servers uses TLS 1.3 with SHA-256 certificate validation.
• At-Rest Encryption: Backup archives stored in our central cloud vault are encrypted using AES-256 (Advanced Encryption Standard with 256-bit keys).
• Per-Account Secret Keys: Each business account is allocated a unique vault namespace that isolates your company's database snapshots from other subscribers.

5. 1-Click Disaster Recovery & Hardware Replacement

Accidents happen — hard drives fail, laptops get damaged, and operating systems can crash. INLedger makes recovery immediate and painless:

• Zero License Keys to Find: Download INLedger on your replacement PC and log in with your account email and password.
• Instant Cloud Restore: The software automatically verifies your subscription entitlement and downloads your latest encrypted database snapshot from the cloud vault.
• Complete Continuity: All your customer ledgers, item pricing, pending receivables, and tax invoices are restored in minutes, ready for billing.

6. Multi-Terminal Synchronized Ecosystem

For multi-counter retail stores, distributors, and supermarkets running the Professional Plan:

• Counter 1 (Main Billing POS): Fast thermal billing operates locally and streams sales to the cloud vault.
• Counter 2 / Admin Terminal: Live dashboard reflects updated stock levels, purchase vouchers, and receivables in real time.
• CA / Auditor Access: Your accountant can log in from a separate authorized terminal to audit ledgers and generate GST return files without interrupting sales counters.

7. Security Compliance & Standards

Our infrastructure adheres to stringent information security benchmarks:

• ISO/IEC 27001 Certified Tier-IV Data Centers: Cloud servers are housed in enterprise facilities with biometric access controls, uninterruptible power, and climate monitoring.
• DPDP Act 2023 Compliance: We adhere to India's Digital Personal Data Protection standards regarding data minimization, consent, and user data rights.
• PCI-DSS Certified Payment Gateway: Online subscriptions are powered through Razorpay under Level 1 PCI-DSS compliance.
