Privacy policy

In short: this website does not use cookies, tracking or analytics. Your jig measurements stay in your browser. Personal data is only processed when the website is delivered to you and when you send a message through one of the forms.

1. Controller

The controller responsible for data processing on this website is:

2. Hosting and delivery (Cloudflare)

This website is hosted and delivered by Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA (“Cloudflare”). When you open the website, Cloudflare necessarily processes technical data such as your IP address, the date and time of the request, the page requested, your browser and operating system, and the referring website. This is needed to deliver the website securely and to protect it against attacks.

Legal basis is Art. 6(1)(f) GDPR (legitimate interest in a secure and reliable website). Cloudflare processes the data on my behalf under a data processing agreement. Data may be transferred to the USA; Cloudflare is certified under the EU-U.S. Data Privacy Framework, for which the European Commission has issued an adequacy decision. More information: cloudflare.com/privacypolicy.

3. The jig tools

The jigs are calculated entirely in your browser. The measurements you enter are not sent to me or to anyone else. They only appear in the address bar of your browser, so that you can bookmark or share a jig. Nothing is stored on your device beyond what your browser keeps in its normal cache.

4. Feedback form and print requests

If you send feedback or a print request, the following data is transmitted: your message, and if you enter them, your name and email address. With a print request, the STEP file of the jig and a link to its settings are also sent. The data is passed through Cloudflare (see section 2) and delivered to my email inbox at Google Ireland Ltd. (Gmail).

I use the data only to read and answer your message and, for a print request, to discuss the print with you. Legal basis is Art. 6(1)(b) GDPR for print requests (steps prior to a possible agreement) and Art. 6(1)(f) GDPR for feedback (legitimate interest in answering messages and improving the website). The data is deleted once your request has been dealt with, unless legal retention periods require otherwise.

Giving your name and email address is optional for feedback. Without an email address I cannot reply.

5. Email

If you write to me by email, your email address and the content of your message are processed to answer you. The same purposes, legal bases and deletion rules as in section 4 apply.

6. Your rights

Under the GDPR you have the right to:

• access your personal data (Art. 15),
• have it corrected (Art. 16) or deleted (Art. 17),
• restrict its processing (Art. 18),
• receive it in a portable format (Art. 20),
• object to processing based on legitimate interest (Art. 21).

To exercise these rights, write to the email address above. You also have the right to lodge a complaint with a data protection supervisory authority, for example the authority of the German federal state where you live.

7. No cookies, no tracking

This website does not set cookies and does not use analytics, advertising or social media plugins. It does not load fonts or scripts from other providers.
