Terms of Use

✦1. What This Is

Presentation Brain is a gesture-driven presentation tool by Nathalie Chou Lab, currently offered free of charge as pre-release software. It is provided "as is" and "as available", without warranties of any kind — including fitness for a particular purpose. Rehearse with it before any presentation that matters; pre-release software can misbehave at the worst moment, and you use it at your own risk.

The public app is the free Brain edition — provided as-is, as described above. The full edition (decks, slide control, and the local helper) is shared by invitation only and unlocked with a passphrase; these same terms apply to both.

✦2. The Waitlist

Joining the cloud waitlist creates no obligation on either side — it is not a purchase, a reservation, or a promise that the cloud edition will launch on any date, at any price, or at all. If and when a paid cloud tier launches, it will be offered under its own terms of service, presented to you before you pay anything.

✦3. Ownership

Presentation Brain's software, design, name, and content are © 2026 Nathalie Chou Lab — all rights reserved, proprietary, and not open source. No license is granted to copy, modify, reverse-engineer, or redistribute any part of it. Your decks and notes are, of course, entirely yours — the tool claims no rights whatsoever over what you present.

✦4. Liability

To the maximum extent permitted by law, Nathalie Chou Lab and its operator shall not be liable for indirect, incidental, or consequential damages — including a presentation that goes wrong — arising from use of this free tool; total aggregate liability shall not exceed USD 50. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.

✦5. Governing Law, Changes, Contact

These terms are governed by the laws of the State of Washington, USA. They may be updated from time to time; the date above reflects the latest revision. Questions: nathalie.studio/contact.html · The site's Privacy Policy forms part of these terms.
