Is my data safe?
Absolutely. All data is stored locally in your browser using Chrome's Storage API. We don't have servers that collect your data. The only external communication is directly with official government APIs (EU VIES at ec.europa.eu, Swiss UID at uid.admin.ch, Norwegian Brønnøysund at brreg.no). Your verification history never leaves your device.
What is the Pro license?

How do I activate my Pro license?
After purchase, you'll receive a license key via email. Open the extension, click "Upgrade to Pro" or go to Settings, paste your license key, and click Activate. The license is valid for up to 3 devices and never expires.
What is the VIES consultation number?
The VIES consultation number (requestIdentifier) is an official reference provided by the EU VIES system for each validation. This number serves as legal proof that you verified a VAT number at a specific date/time — essential for tax audits. Pro PDFs include this number automatically.
Why do I need to verify VAT numbers?
EU law requires sellers to verify buyer VAT numbers for B2B intra-community sales to apply reverse charge (0% VAT). Without valid proof of verification, you may be liable for the uncollected VAT plus penalties. This extension provides quick verification and audit-ready documentation.
