SDK & Extension Development for UK Businesses
SDK & Extension Development — UK
UK enterprise buyers expect clear privacy disclosures under UK GDPR for any extension or SDK that touches user data, and procurement teams review permission models closely before approving a browser tool. Tantrija builds extensions and SDKs engineered for that scrutiny — UK GDPR-aware data handling, clean permission models, and documentation built for enterprise procurement review.
