Privacy policy

Last updated: 26 September 2026

Short version: the application works on your computer and does not send your models anywhere; this website uses no cookies and no analytics.

1. Who is responsible

Américo Mateus Rodrigues, Rua Diu n.º 5, 1.º Dto., 2685-326 Prior Velho, Portugal, NIF (VAT number) PT 207991952, trading as Isometra, is the controller of the personal data described here. Contact: [email protected].

2. The application

  • Isometra Workbench runs locally. Models, drawings, comments and projects stay on your computer; we do not receive or store them.
  • The licence is a file on your computer. The Software checks it there and does not contact us to do so.

3. This website

  • No cookies, no analytics, no advertising and no third-party scripts or fonts. Everything the site needs is served from our own domain.
  • The site is hosted on Cloudflare. As with any web server, Cloudflare processes technical data such as your IP address, browser type and the pages requested, to deliver the site and protect it from abuse.

4. When you write to us

If you email [email protected] we use your email address and what you tell us to answer you, to provide support and, if you buy, to manage your licence. Email to this address is forwarded to our mailbox, which is provided by Google (Gmail).

5. When you buy

Today we invoice you ourselves and you pay by bank transfer, so we hold the billing details you send us (your full name, email address and tax number, and, if it is a company, its name, address and country), the invoice and the payment record, and the licence details. The name and email address of each user are also written in that user’s licence file (you see them in Help > Licence), so a copy can be traced to who bought it. For a refund we ask for the same name, email and tax number, to match the request to the payment. Because each licence file is tied to one computer, you also send us the Machine ID that the Software shows in Help > Licence. It is a code derived from the computer’s identifier by a one-way function; we cannot read the identifier from it, and we use it only to issue the licence file. We do not receive card details. If we later use a payment provider, we will say so before you buy, and its own privacy policy will apply to what it processes.

6. Why we use data, and for how long

  • To deliver what you asked for (answering you, issuing and renewing a licence, support): while the relationship lasts.
  • To meet legal duties (invoicing, tax and accounting records): for the period the law requires, generally several years.
  • Legitimate interest (keeping the site secure): logs are kept by Cloudflare for a short period.

We do not sell personal data and we do not use it for advertising.

7. Who else sees it

Only the service providers named above (Cloudflare for hosting and email forwarding, Google for the mailbox, the payment provider) and, where the law requires it, authorities. Some of them may process data outside the European Economic Area under the safeguards the law provides, such as standard contractual clauses.

8. Your rights

You can ask us to access, correct, delete or export your data, to restrict or object to its use, and to withdraw consent where we rely on it. Write to [email protected]. You also have the right to complain to the data protection authority of your country; in Portugal this is the CNPD (cnpd.pt).

9. Changes

If this policy changes in a way that matters, we will update the date above and, for customers, tell you by email.
