Privacy policy

Last updated: November 15, 2026

3DVWR collects no data about you. The app works offline, has no account, no analytics and no ads, and never uploads a file.

Who is responsible

The app

Your files

3DVWR reads the files you open and shows them on your Mac. It does not send them, or anything derived from them, anywhere. The same applies to the Quick Look preview and to the thumbnails in Finder.

macOS runs the app in its sandbox. It can read a file you open and a folder you explicitly allow, for example so that a model can load the textures stored next to it. It cannot read the rest of your disk.

No network connections

The app does not connect to the internet. If a model file refers to textures or other resources on a web server, 3DVWR does not load them. The entries in the Help menu open this website in your browser; what the website processes is described below.

What the app keeps on your Mac

To work the way you left it, the app stores a few things locally:

• the list of recently opened files,
• your view settings, such as appearance, look and background,
• the folders you allowed it to read.

This information stays on your Mac. I have no access to it.

Mac App Store

If you get 3DVWR from the Mac App Store, Apple processes the download and any payment under Apple's privacy policy. Apple does not give me your name, your Apple Account or your contact details. If you chose in macOS to share analytics with app developers, Apple provides me with aggregated usage statistics and crash reports that do not identify you.

This website

Connection data

When you open this website, the server processes the connection data that is technically required: your IP address, date and time, the requested resource and the information your browser sends about itself and your operating system (user agent). This is necessary to deliver the pages and to keep the server secure.

The legal basis is Art. 6(1)(f) GDPR. My legitimate interest is a reliable, secure and working website.

Hosting

The website runs on my server at Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany. Hetzner provides the server infrastructure and is involved in the technical processing as a hosting provider. The server is located in Hetzner's data center in Helsinki, Finland, within the European Union.

The regular access log of the website's web server is switched off. That does not mean that no log data exists at any level: upstream services and the hosting infrastructure may process connection or security data.

Connection data is needed to answer the request. Where technical logs are required to analyze operation or security, they are kept as long as they are needed to detect, contain and fix a fault or a security incident, and deleted afterwards.

No cookies, no tracking, no third parties

This website sets no cookies and stores nothing in your browser. It has no visitor statistics. Fonts, style sheets, scripts and images are loaded from this website; no font service, content delivery network or other external server is contacted.

Links to other websites

Links to the Mac App Store, to my legal notice on biermann.dev and to other websites are plain links. A connection to those sites is only made when you follow a link. From then on, the privacy policy of that site applies.

When you write to me

If you send me an email, I process your email address, the content of your message and the information and files you send along, in order to answer you and to solve your problem. The legal basis is Art. 6(1)(f) GDPR; my legitimate interest is handling support requests.

I keep the correspondence as long as it is needed to handle your request and to be able to follow it up. After that it is deleted, unless legal retention duties or the defense of legal claims require otherwise.

Your rights

Under the conditions of the GDPR you have the right to:

• access the data processed about you (Art. 15),
• have incorrect data corrected and incomplete data completed (Art. 16),
• have your data erased and its processing restricted (Art. 17 and 18),
• receive your data in a portable format, where the conditions are met (Art. 20),
• object to processing based on Art. 6(1)(f) GDPR on grounds relating to your particular situation (Art. 21).

You are neither legally nor contractually obliged to provide personal data. Without the technically required connection data the website cannot be delivered, and without a reply address I cannot answer you. There is no automated decision-making or profiling.

You also have the right to lodge a complaint with a data protection supervisory authority (Art. 77 GDPR), in particular where you live or work or where you believe the infringement took place. The authority responsible for me is:
