SDK & Extension Development for European Businesses
SDK & Extension Development — Europe
GDPR and the ePrivacy Directive shape how every browser extension or SDK in the EU handles personal data and consent, and enterprise buyers review permission models closely before approval. Tantrija builds extensions and SDKs engineered for that landscape — GDPR-compliant data handling, ePrivacy-aware consent flows, and documentation built for EU enterprise procurement review.
