EyeFitU SizeEngine is a SaaS platform that helps fashion and footwear web shops let customers choose a fitting size. It uses machine learning and includes SizeFinder for size recommendations after a short onboarding, SizeVisualizer for a personalised view of garment fit, fit-preference settings, and analytics on size and behaviour data. According to the vendor it works with any e-commerce platform, with direct integrations for Oracle, Shopify and WooCommerce. For footwear there is also the FootScanner.

SizeEngine is offered by EyeFitU AG, based in Herrliberg near Zurich, Switzerland. No foreign parent company is stated. According to the privacy policy, personal data is held in the company's own database or with service providers located in the European Union, and the vendor says it fully complies with the GDPR. Swiss law governs the terms. Switzerland is not an EU member state but is an EFTA country with an EU adequacy decision. Ask which service providers are used in your case.

Why digital sovereignty matters with EyeFitU SizeEngine

EyeFitU SizeEngine is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Data is hosted exclusively in the EU, so EyeFitU SizeEngine scores best on data residency.

EyeFitU SizeEngine is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs EyeFitU SizeEngine together with your other vendors and gives a total score, a heatmap and the main risk drivers.
