Terms of Service
Last updated September 2026
Using the service
The Master Key Library and Experience are provided for personal study. By using them you agree to these terms and to our Privacy Policy. You must be old enough to consent to data processing in your jurisdiction.
Your account
You are responsible for activity under your account and for keeping your sign-in secure. Do not attempt to disrupt, overload, scrape at scale, or circumvent access controls or rate limits.
Library content
Each book page states the rights position for that text. The editorial and AI-assisted enrichment (summaries, definitions, imagery) is Better Thought's. Enrichment may contain inaccuracies; it is offered for study, not as authoritative reference. If you believe a work is presented in error, contact us for prompt review or takedown.
Community contributions
Content you post (such as ledger insights) must be lawful and respectful: no hateful, harassing, infringing, or unlawful material. We may edit, hide, or remove contributions and suspend accounts that violate these terms.
No warranty
The service is provided “as is,” without warranties of any kind. To the extent permitted by law, we are not liable for indirect or consequential damages arising from its use.
Changes
We may update these terms; material changes will be posted here. Continued use after changes means you accept them.
