Data portability for fit
The ability for body and fit data to move with the customer across brands, ateliers, and platforms.
Definition
Measurement Portability is the portability mechanism within Size Passport that lets a person's fit data move from one brand, atelier, or platform to another — without re-measurement, data loss, or lock-in to any operator.
For the person
It means not repeating the same measurements every time a new tailor, brand, or stylist enters the relationship.
For the ecosystem
Portability is the wedge that turns fragmented tailoring data into a network layer with interoperability potential.
Why it matters
It reframes fit as customer-owned infrastructure rather than operator-owned residue from a transaction.
Normalizes body and garment measurements into reusable records.
Attaches permission logic so portability does not break privacy.
Keeps historical context so the receiving operator can interpret the data correctly.

Trusted system for shared fit records
Portability only scales when the storage and permission model are not brand-bound.
Brand-neutral fit translation
Cross-brand sizing is impossible if measurements cannot travel.
Shared language for fit records
Interoperability begins with portable data definitions.
Questions answered clearly
No. Export is one expression. Portability also means shared interpretation, permissions, and continuity across approved operators.
Because it changes who owns the data relationship and makes the platform useful across multiple brands instead of inside a single stack.
Data export is a one-time action that produces a file. Portability is a standing architecture — fit data remains continuously reusable, shareable, and interpretable across any approved operator, not only when a manual export is triggered.
GDPR Article 20 establishes data portability as a legal right for EU residents. Size Passport is designed to operationalize this right for fit data specifically — making technical portability as durable as the legal entitlement.
