How can I uninstall PhotoPipr?

On macOS, drag the PhotoPipr application to the trash. If you wish to delete all the files created by PhotoPipr, read the next question.

Where are the program data files?

PhotoPipr places its configuration files, authorization token(s), and log files in a directory named .photopipr in your home directory. If you want to back up your workflow definitions and program state, this directory contains what you are looking for. Uninstalling PhotoPipr will not delete this directory, so if you want to get rid of all of PhotoPipr's files, you will need to delete this directory manually.

Warning: If you delete these data files, you will lose all of your workflow definitions.

What are the system requirements?

PhotoPipr is written in Java, and should run on nearly any macOS system that is compatible with Java 17. See the Download page for more information.

What are the license terms?

PhotoPipr is licensed under the GNU General Public License, Version 3. You are free to use and modify the code, but your changes must be distributed under the same license. If you want to help develop PhotoPipr, head over to github.
