FAQ
Q. Can I use it for free?
A. There is a 30-day free trial, and after the trial period ends, you can purchase it for 300 JPY.
Q. Why is there no tree view?
A. A tree view takes up screen width and sometimes requires horizontal scrolling, which we believe reduces usability. We are currently considering alternative UI solutions, so if you have any ideas, please feel free to let us know!
Q. Are tags and favorites written directly into files?
A. No. Tags and favorites are managed in PicSum's own database. Nothing is written into your files.
Q. I cannot move, delete, or rename files.
A. Modifying files is an operation that requires caution. PicSum is designed to be read-only so you can use it with peace of mind without worrying about unintended file modifications. However, exporting (copying) files is supported.
