Personal-use terms

Effective November 2, 2026. OSSUS Substack Books is personal-use software under development for its owner’s private reading library, not a public sign-up service.

The owner is responsible for using only content they are entitled to access. Combining authorized chapters into a private reading file does not grant redistribution rights. Google, Substack, and other third-party services remain subject to their own terms.

The application may change or be stopped by its owner. There is no promise of uninterrupted availability, complete archives, or recovery of every third-party revision. Keep recoverable copies of source material and reading data.

These pages do not offer access to a hosted mailbox or reading service. See the privacy policy for data handling and the support address on Google’s consent screen for contact.
