TimeStory is a macOS app which works with document files on your computer (or on your personal cloud storage). What you put into those documents, and where you send them, is totally up to you.
The above statement applies to any version of TimeStory, including the free trial edition.
If you contact email@example.com to report bugs, provide feedback, make requests, or anything else, I will treat your messages as confidential unless you explicitly tell me otherwise, and I will not share your contact information with anyone unless required by law.

The only third-party service it uses is Google Fonts, to supply the custom font; their privacy statement is here.
