This is a summary for IT and other departments for buying VDA QMC products
Licensing
Named Licensing Model
Each tool is licensed to a specific user (“named license”).
The same user can install and use the tool on any number of devices.
If needed, license ownership can be transferred by submitting a request to the Webshop.
Licenses do not expire for the current version of the product, and all minor updates are included.
Support and updates continue for at least three years, or as long as the associated book/rules remain current.
Software
Browser-Based Progressive Web App (PWA)
Runs in modern browsers with full JavaScript support.
Optimized primarily for tablets and workstations, with limited optimization for mobile devices.
Operates fully offline after initial installation, as long as the browser’s cache is not cleared.
Update & Licensing Model
The server is only needed to download the latest version and perform periodic license checks (typically every 2–4 weeks).
If the product integrates with a REST API backend, additional server communication is used for data exchange.
All server interactions (e.g., license requests or API calls) trigger user-visible status messages.
Technical Stack
Built with Angular (legacy products use AngularJS) alongside various open-source libraries.
Designed primarily for offline operation, with a file-based architecture.
All data is stored in JSON files, facilitating easy data exchange.
IndexedDB is used for convenient local storage, though it is not intended as a permanent data repository.
Certifications
Because the product does not store any data outside the client’s device—and we have no access to that data—we currently have no plans to pursue cloud-related certifications such as TSIAX.
