Privacy Policy

Last updated: 3 July 2026

Welcome to Flux Stock, developed by idocode. Flux Stock is an "offline-first" application, which means your data lives on your own computer and stays under your control. This policy explains exactly what the application stores and how it is protected.

1. We Do Not Collect Your Data

Flux Stock runs entirely on your computer. We do not collect, receive, store, or transmit your business data, not to idocode, and not to any third party. The application contains no analytics, no usage tracking, and no crash reporting, and it does not need an internet connection to work.

2. What Is Stored on Your Device

Everything you enter is kept only in a local database on your computer. This includes:

  • Products & inventory: your product catalog, cost and selling prices, price tiers and volume discounts, and stock levels and movements.
  • Customers & suppliers: names, phone numbers, emails and addresses, along with any fiscal identifiers you choose to record (NIF, RC, AI, NIS), credit limits and payment terms.
  • Financial records: invoices, quotes, sales and purchases, payments, credit and debit notes, and receivables and payables.
  • Your company profile: business name, contact details, tax identifiers, logo and invoice settings.
  • Activity log: the app keeps an internal record of important actions, what changed, the user role that made the change, and when, so you have your own audit trail. This record never leaves your device.

3. How Your Data Is Protected

  • Automatic encryption: your database is automatically encrypted on your device using AES-256, with a key tied to this computer. A copy of the database file cannot be opened on another machine.
  • Protected backups & exports: when you create a manual backup or export a file (database or CSV), you can set your own password to encrypt it. Keep this password safe, it cannot be recovered if lost.
  • You stay in control: at any time you can export your data, back it up, or permanently erase it, including a full factory reset, from the Settings screen.

4. Software Licensing

To confirm that your license is valid, Flux Stock creates a unique fingerprint from your computer's hardware. This fingerprint is stored locally and on your USB license key, and is used only to verify your license on this machine. It is never transmitted to idocode or anyone else, licensing works completely offline.
