Security & Data Ownership
Practical safeguards engineered for everyday business realities: local data sovereignty, secure cashier authentication, and full data portability.
Local Database Sovereignty
Your business transactions, product catalog, customer directories, and daily sales records live locally on your computer inside an embedded SQLite database. Your business data remains your property on your premises.
Argon2id Staff PIN & Password Hashing
Staff PINs and manager credentials are mathematically hashed with Argon2id (memory-hard, brute-force resistant) before touching disk. Plaintext passwords or PINs are never stored in the database.
Role-Based Cashier & Manager Permissions
Staff access is strictly segregated into Cashier, Manager, and Admin roles. High-risk counter actions—such as line voids, refunds, manual discounts, and cash drawer opens without a sale—require manager PIN approval.
OS Keychain Credential Storage
Cloud sync tokens and API secrets are stored within the native operating system vault (Windows Credential Manager) via Rust system bridges, preventing plaintext exposure in config files.
Local & Cloud Disaster Recovery Backups
OneScale enables direct local database backup exports to USB drives, alongside automated encrypted cloud backups when internet is active, so you can restore your shop operations immediately if a machine fails.
Full Data Portability & CSV Export
No proprietary vendor lock-in. Store owners can export complete product catalogs, customer histories, inventory adjustments, and sales ledgers to standard CSV and Excel formats at any time.
Opt-In Error Diagnostics with PII Scrubbing
Crash and diagnostic reporting is strictly opt-in. When enabled by the owner, automated scrubbers strip customer phone numbers, names, and card details before any telemetry leaves the device.
Encrypted Cloud Transport (TLS 1.3)
All background cloud synchronization between local registers and the web back-office is transmitted securely over TLS 1.3 HTTPS channels with verified certificates.
Our Core Operational Commitments to Store Owners
Zero Lock-in Guarantee
Your customer records, inventory quantities, and sales logs can be exported to standard Excel / CSV sheets at any time.
No Advertising Monetization
We never sell, rent, or share customer contact numbers or transactional data with third-party advertisers or marketing brokers.
Local Hardware Control
Your POS software continues operating and printing receipts locally even if your internet connection goes down for days.
