Privacy Policy

Updated4 November 2026

PatronIA attaches great importance to the protection of your personal data. This policy describes what data we collect, why, and how we protect it, in accordance with the General Data Protection Regulation (GDPR — Regulation (EU) 2016/679).

Body measurements

The body measurements you enter (bust, waist, hip, lengths…) are used exclusively for making made-to-measure garment patterns. In this purely clothing-related context, they do not constitute data concerning health within the meaning of Article 9 of the GDPR: they are processed on the basis of the performance of the contract, only to generate your patterns, and are never used for any other purpose.

Your bust, waist and hip measurements and, if you have entered them, the skirt length and inside leg are sent to Anthropic to write the sewing instructions for your pattern; no photo is attached to that transmission. To build, check or correct the pattern you have ordered, all your body measurements and your photos are also sent to the studio's assistant, a programme that runs from our servers using Anthropic's service, under the data processing agreement that binds us. Your name and e-mail address are never sent to it. Details of what is sent are given in the section Processors, recipients and transfers.

* Transfers outside the EU: Anthropic (United States) — for transmissions via the API, standard contractual clauses of the European Commission incorporated into its data processing agreement; for the studio's assistance, see below. For our other providers located outside the EU, the applicable safeguards (standard contractual clauses or Data Privacy Framework) can be obtained on request from [email protected].

What we send to Anthropic: for reading the garment, your photos (the main view and, if you add them, the back and the detail); for writing the sewing instructions, the description of the garment resulting from that reading, some of your body measurements (bust, waist and hip, and where applicable skirt length and inside leg) and the characteristics of the drafted pattern (pieces, dimensions). The pattern itself is drafted by our pattern-cutting programme, without artificial intelligence.

For the studio's assistance, which builds, checks and, if needed, corrects the patterns ordered, for each of your paid projects: the initial of your name, the photos, the analysis of the garment, all your body measurements, your choices and the status of your order in credits. Never your name, your e-mail address or your payment data.

This assistance runs mainly through Anthropic's API, from our servers. It is then covered by the data processing agreement and the standard contractual clauses described above: the data are not used to train the models, and the files sent are deleted at Anthropic once the order has been processed.

Part of the checking may still go through a Claude account of the studio for which the model improvement option is switched off: these data are not used to train Anthropic's models. This route is not covered by the data processing agreement: Anthropic then processes these data in the United States under its own terms of use and privacy policy. Every reading is logged.

The data sent for reading the garment and writing the sewing instructions are not used to train Anthropic's models: in accordance with the terms of the Anthropic API, they are used only to produce the requested response and are not reused for training purposes.
