Hosting on GitHub Pages

This website is hosted by GitHub Pages, a service of GitHub, Inc., 88 Colin P. Kelly Jr. Street, San Francisco, CA 94107, USA. When you open a page, your browser sends technical data to GitHub’s servers, including your IP address, the requested page, date and time, and your browser type. GitHub needs this data to deliver the website and to protect it against attacks, and stores it in server log files.

Some images on this website and all PIVlab downloads are also delivered by GitHub (github.com, raw.githubusercontent.com).

To show download buttons for a beta version when one exists, your browser asks GitHub’s interface (api.github.com) for the list of PIVlab releases, at most once per hour; GitHub receives your IP address with this request.

The legal basis is our legitimate interest in presenting the website and its downloads reliably and securely (Art. 6 (1) (f) GDPR). Data may be transferred to the USA. GitHub is certified under the EU-U.S. Data Privacy Framework. More information: GitHub Privacy Statement.

YouTube videos

Videos on this website are embedded in YouTube’s privacy-enhanced mode (youtube-nocookie.com). Nothing is loaded from YouTube until you click a video. When you click, the video is loaded from the servers of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, and your IP address and technical data are transmitted to Google. Google may also transfer data to the USA. The legal basis is your consent, given by clicking the video (Art. 6 (1) (a) GDPR). More information: Google Privacy Policy.

Settings stored in your browser

When you switch between light and dark mode, or between the PIVlab versions on the setup pages (for example “Standalone app” / “MATLAB toolbox”), your choice is stored in your browser’s local storage, so the website remembers it. The result of the beta check (see above) is kept in your browser’s session storage for one hour. This data stays on your device and is never sent to us or anyone else. You can delete it at any time in your browser settings.

Contact by email

If you contact us by email, we process your email address and your message to answer your request (Art. 6 (1) (b) and (f) GDPR). We delete this data when it is no longer needed, unless legal retention periods apply.

Links to other websites

This website links to other websites, for example the PIVlab forum on Google Groups, MathWorks, and camera manufacturers. Their own privacy policies apply when you visit them.

Your rights

You have the right to access your personal data, to have it corrected or deleted, to restrict its processing, to data portability, and to object to its processing (Art. 15–21 GDPR). You can withdraw a consent at any time with effect for the future. To exercise these rights, contact us at info@optolution.com.

You also have the right to lodge a complaint with a data protection supervisory authority, for example the State Commissioner for Data Protection and Freedom of Information Baden-Württemberg (Landesbeauftragter für den Datenschutz und die Informationsfreiheit Baden-Württemberg).
