1. Privacy Commitment & Fundamental Principles

At ContaExperto ERP, we recognize that our clients' financial and accounting records represent their most confidential corporate asset. This Privacy Policy transparently outlines how we collect, safeguard, process, and protect your personal and corporate financial data.

Exclusive Purpose Principle We strictly process data necessary to operate the cloud accounting ERP and provide contracted software services.
Non-Invasion Principle We never commercialize, monetize, or profile your balance sheets, journal vouchers, or tax books.

2. Information We Collect

We categorize the processed data into the following three categories:

  • A. Registration & Identity Data Administrator full name, corporate email address, issuing phone number, and encrypted password (stored solely via one-way cryptographic hash).
  • B. Billing & Subscription Data Company legal name, Tax ID / Corporate ID number, billing address, wire transfer or Mobile Payment reference numbers, and subscription tier status.
  • C. Tenant Accounting Data NIIF/IFRS chart of accounts, journal entries, vouchers, bank balances, and fixed asset depreciation ledgers. This data is stored strictly in your dedicated, isolated PostgreSQL schema.
03

3. Purpose of Processing Data

We use the information collected solely for the following legitimate business purposes:

  • Provisioning and maintaining your active multi-tenant workspace and organization database schema.
  • Generating trial balances, journals, general ledgers, and financial statements as requested by authorized users.
  • Validating and processing subscription orders and reconciling payment transactions.
  • Transmitting critical transactional notices (account verification, security alerts, and invoice confirmations).
  • Delivering dedicated accounting software support upon explicit customer inquiry.

4. Technical Isolation & Encryption Safeguards

We implement a defense-in-depth architecture designed for enterprise-grade financial systems:

Transit and Rest Encryption

All web and API traffic is encrypted via TLS 1.3 (256-bit SSL certificates). At rest, all database storage volumes and backups are encrypted utilizing 256-bit AES algorithms.

PostgreSQL Schema Logical Isolation

Each connection sets the organization's schema route dynamically (SET search_path = tenant_schema), preventing cross-tenant leakage.

  • Transactional Email Services: Secure SMTP dispatch strictly for system notifications and verification tokens.
  • Official Rate APIs: Read-only queries to central bank feeds for official exchange rates.
