Privacy policy

Last updated: 13 November 2026

This policy applies to the website perfboardlab.com. The Perfboard Lab app has its own privacy policy.

1. Controller

2. Visiting the website

When you open this website, your browser sends technically necessary data to the server. These are your IP address, the date and time of the request, the address requested, the page you come from and details of your browser and operating system. Without these data the server cannot deliver the page.

The website is hosted by Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA (Cloudflare Pages). Cloudflare processes these data on my behalf in order to deliver the pages and to protect them against attacks. A data processing agreement according to Art. 28 GDPR is in place. Cloudflare answers your request in a data centre close to you, which may be outside the European Union. Cloudflare is certified under the EU-US Data Privacy Framework. For the USA, an adequacy decision of the European Commission therefore applies (Art. 45 GDPR). For other countries, the standard contractual clauses of the European Commission apply (Art. 46(2)(c) GDPR), which are part of the agreement.

The domain’s name service (DNS) is run by STRATO GmbH (section 6). If you open the address without “www”, a server of STRATO forwards you to this website. STRATO processes the same data on my behalf. The data processing agreement with STRATO covers this as well.

Cloudflare analyses the data in order to detect and fend off attacks and then deletes them according to its own retention periods. I do not see any logs with IP addresses myself, only aggregated numbers, for example how often the website was opened. I cannot identify a person from them and I do not combine the data with other data.

The legal basis is Art. 6(1)(f) GDPR. My legitimate interest is the secure and error-free operation of the website. This includes knowing how often the pages are opened.

3. Cookies and browser storage

This website sets no cookies. It puts nothing else into your browser by which it could recognise you, and it reads no information from your device. That is why there is no cookie banner here.

At this website’s request, your browser remembers two technical things. It keeps the style sheet and the pictures of the website for a short time so that the pages load faster. It also remembers to open this website only over an encrypted connection. Both are strictly necessary for secure operation (Section 25(2) no. 2 TDDDG) and contain no information about you.

With every request, Cloudflare also sends an instruction for error reports (Network Error Logging). Some browsers, for example Chrome and Edge, remember this instruction for seven days. If your browser cannot load the website during this time because of a network error, it reports this to Cloudflare. The report contains the address you opened and the kind of error, and Cloudflare receives your IP address with it. Cloudflare uses this to detect faults in its network. On Cloudflare Pages I cannot switch this instruction off. Safari and Firefox ignore it.

4. No analytics, no third-party content

The website uses no analytics and no advertising services. Images and all other files come from this website itself (at Cloudflare, see section 2). No content of other providers is embedded, for example no videos from video platforms and no fonts from the web.

5. Links to other websites

The website contains links to other providers, for example to Apple’s App Store. Data only go to that provider once you open the link. From then on, that provider’s privacy policy applies.

6. Contact by email

If you write me an email, I process your email address and the content of your message in order to reply. The legal basis is Art. 6(1)(f) GDPR. My legitimate interest is to answer your request. If the message concerns a contract, the legal basis is Art. 6(1)(b) GDPR.

My mailbox is hosted by STRATO GmbH, Otto-Ostrowski-Straße 7, 10249 Berlin, Germany. The servers are located in Germany. A data processing agreement according to Art. 28 GDPR is in place with STRATO for this.

I delete the messages once your request is settled and no statutory retention duty applies.

7. Your rights

Under the GDPR you have the following rights:

• Access to your data (Art. 15)
• Rectification of incorrect data (Art. 16)
• Erasure of your data (Art. 17)
• Restriction of processing (Art. 18)
• Data portability (Art. 20)

Right to object (Art. 21 GDPR): You can object at any time to the processing of your data that is based on Art. 6(1)(f) GDPR. The grounds must relate to your particular situation.

For all rights, an email to info@perfboardlab.com is enough.

You can also lodge a complaint with a data protection supervisory authority (Art. 77 GDPR). The authority responsible for me is the Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen, Kavalleriestraße 2–4, 40213 Düsseldorf, Germany, www.ldi.nrw.de.

8. No obligation, no automated decision

You are not obliged to provide data. Without the technically necessary data from section 2, however, the website cannot be displayed. There is no automated decision-making and no profiling.

9. Changes

When the website changes, I update this policy. The version shown here applies.
