Privacy policy.

1. Data Collected for Licensing & Billing: SmartSDC collects merchant contact details, Taxpayer Identification Numbers (TIN) when provided for commercial invoicing, payment transaction identifiers from Stripe and PayPal, and workstation Hardware IDs required to bind device licenses.

2. Local Fiscal Data Isolation: SmartSDC's cloud licensing platform never ingests or stores your retail line-item receipts. All fiscal invoice signing and FRCS TaxCore audit package queuing occur locally on your Windows workstation inside ESDC.CoreService.

3. Opportunistic Telemetry & Clock Advisories: When an E-SDC workstation is online, it may verify license status and report system clock drift so administrators can maintain NTP compliance across branches.

4. Security & Retention: Account credentials are encrypted with bcrypt, payment card numbers are processed directly by Stripe and PayPal (PCI-DSS Level 1), and license audit logs are retained for regulatory verification.
