Security & privacy
Erynva separates document processing from optional online account services. Your files, OCR text and extracted details stay on your computer.
Stays on your device
Only when you use account features
Local processing flow
Text layers and Apple Vision or Windows OCR read supported documents on the device.
A downloaded local model extracts only the fields selected in your filename preset.
Review, corrections, history and file operations remain on the same computer.
Account-service providers
Online providers are used only for the website, authentication, billing, downloads and optional account features—not to process document content.
Authentication, account records and protected service functions.
Hosted checkout, subscription billing and customer portal.
Optional Google sign-in when you choose that method.
Website delivery, DNS, security and basic request logs.
Security is a continuing process. To report a potential vulnerability without including private documents, contact support@erynva.com.
