Effective date: 16 October 2026
1. Acceptance of terms
By accessing or using Otis on the web (appotis.com) or on iPhone and iPad, you agree to these Terms of Service. If you do not agree, please do not use Otis.
2. The service
Otis is an AI presentation designer. You describe what you need, Otis asks questions to complete the brief, and then it creates a slide deck you can preview, edit by chat, and download. The service includes:
- AI deck creation from prompts, notes, data, and images you provide
- Redesign of PDF, Word, PowerPoint, and image files you upload
- Edits by chat, and PDF and PowerPoint downloads
- My Decks storage, account, and subscription management
3. Your account
You need an account to create decks. You are responsible for activity on your account and for keeping access to your email or Google account secure. Don’t share your account with others.
4. Subscriptions and billing
Creating decks requires an Otis Pro subscription. On the web, subscriptions are sold through Stripe; in the apps, through Apple. Subscriptions renew automatically at the end of each billing period until you cancel. You can cancel anytime — on the web in Account → Manage billing, or in your Apple ID settings for app purchases — and you keep access until the end of the period you’ve paid for. Fees are billed in advance and are non-refundable except where required by law or stated on our pricing page. We may change prices with advance notice; changes apply from your next billing period.
5. Fair use
Otis Pro is for your own professional and personal work. To keep the service fast and fair, we apply reasonable usage limits (currently 100 new decks per month) and may rate-limit or suspend automated, abusive, or resale use.
6. AI output
Otis is designed to use only the information you provide or facts it has verified, but AI can still make mistakes. Review your deck before you present or share it. You are responsible for how you use the output.
7. Acceptable use
You agree not to:
- Use Otis to create unlawful, harmful, deceptive, or infringing content
- Upload material you don’t have the right to use
- Attempt to reverse engineer, overload, or gain unauthorised access to Otis
- Use bots or scripts to access the service, or resell access
8. Your content and our rights
You own the content you provide and the decks Otis creates for you. You grant us a limited licence to host, process, and display your content solely to provide the service to you. The Otis software, brand, and design system remain the property of Otis Technologies.
9. Termination
You can stop using Otis and delete your account at any time. We may suspend or terminate accounts that violate these terms or pose a security or legal risk.
10. Privacy
Our Privacy Policy explains how we collect, use, and protect your information.
11. Disclaimers and limitation of liability
Otis is provided “as is” without warranties of any kind, to the extent permitted by law. We don’t guarantee the service will be uninterrupted or error-free. Our total liability is limited to the amount you paid for Otis in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law, or your statutory rights as a consumer.
12. Changes to these terms
We may update these terms from time to time. We’ll notify you of material changes; continuing to use Otis after they take effect means you accept them.
13. Governing law
These terms are governed by the laws of England and Wales, and disputes are subject to the exclusive jurisdiction of the English courts, without affecting any mandatory consumer protections where you live.
