PLEASE READ THESE TERMS OF SERVICE CAREFULLY. BY CREATING AN ACCOUNT, CLICKING "I AGREE," OR USING ANY PART OF THE OTTO SERVICE, YOU AGREE TO BE LEGALLY BOUND BY THESE TERMS. IF YOU DO NOT AGREE TO ALL OF THESE TERMS, YOU MAY NOT ACCESS OR USE THE SERVICE.
These Terms of Service ("Terms") constitute a legally binding agreement between you ("User," "you," or "your") and Otto AI, Inc. ("Otto," "we," "us," or "our"), governing your access to and use of the Otto AI assistant platform, including all associated software, APIs, websites, mobile applications, and services (collectively, the "Service").
By (a) creating an account, (b) clicking any button indicating acceptance, (c) accessing or using the Service, or (d) otherwise manifesting your assent to these Terms, you represent that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated herein by reference.
If you are accepting these Terms on behalf of a company or other legal entity, you represent that you have the authority to bind that entity to these Terms, in which case "you" refers to that entity.
You must be at least 16 years of age to use this Service. By using the Service, you represent and warrant that you meet this age requirement. If you are under the age of majority in your jurisdiction, you may use the Service only with the involvement of a parent or legal guardian who agrees to these Terms.
Otto is an AI-powered personal assistant that connects to third-party applications and services (such as Gmail, Google Calendar, Google Drive, Slack, Notion, and others) and performs tasks on your behalf through natural language interaction. Otto uses large language models (LLMs) and automated systems to understand requests and execute actions.
The Service includes, but is not limited to: email reading, drafting, and sending; calendar viewing, creation, and modification; task management; web research; document creation and editing; scheduled automations ("Routines"); memory storage and retrieval; and integration management.
We reserve the right to modify, suspend, or discontinue any feature of the Service at any time, with or without notice, without liability to you. We will use reasonable efforts to notify you of material changes.
Registration. To access the Service, you must create an account by providing accurate, current, and complete information including your name, email address, and a password. You agree to keep this information updated.
Account security. You are solely responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You agree to immediately notify us at legal@ottohq.app of any unauthorized use of your account or any other breach of security. We will not be liable for any loss or damage arising from your failure to protect your credentials.
One account per person. You may not create multiple accounts to circumvent plan limits or bans. Accounts are non-transferable.
Account termination by you. You may delete your account at any time from the Settings page. Upon deletion, your data will be permanently removed within 30 days, subject to our data retention obligations described in the Privacy Policy.
You agree to use the Service only for lawful purposes and in accordance with these Terms. You agree not to:
We reserve the right to investigate suspected violations and to suspend or terminate your account without notice if we determine, in our sole discretion, that you have violated these Terms.
Nature of AI outputs. Otto uses artificial intelligence and machine learning models that may produce outputs that are inaccurate, incomplete, outdated, biased, or otherwise unreliable. AI-generated content does not constitute professional advice of any kind.
Not professional advice. Nothing in the Service constitutes legal, medical, financial, tax, investment, psychological, or any other form of professional advice. You should not rely on Otto's outputs as a substitute for qualified professional consultation in any field.
User responsibility for actions. YOU ARE SOLELY RESPONSIBLE FOR ALL ACTIONS TAKEN BY OTTO ON YOUR BEHALF. Before authorizing Otto to send emails, delete data, schedule events, make purchases, or take any other consequential action, you agree to review and verify the intended action. Otto's confirmation prompts are a convenience feature, not a guarantee of accuracy.
No guarantee of results. We do not warrant that the Service will meet your specific requirements, that outputs will be accurate or complete, or that the Service will be uninterrupted, error-free, or secure.
Third-party AI models. The Service uses third-party AI providers (including Anthropic) to process your queries. Your inputs may be transmitted to these providers in accordance with their terms of service and our Privacy Policy.
OAuth connections. To provide its functionality, Otto requires you to grant it access to third-party services via OAuth 2.0 or similar authorization protocols. By connecting a third-party service, you authorize Otto to access and act upon that service on your behalf, within the scopes you grant.
Scope of access. We request only the minimum permissions necessary to provide the features you use. A complete list of permissions requested for each integration is available on the Integrations page.
Third-party terms. Your use of connected third-party services is governed by those services' own terms of service and privacy policies. We are not a party to those agreements and have no control over third-party services, their availability, accuracy, or data practices.
Revoking access. You may disconnect any third-party integration at any time from the Integrations page, which will cause Otto to delete the stored access token and cease accessing that service.
No endorsement. Our integration with any third-party service does not constitute an endorsement of that service.

Otto's use of data obtained from Google APIs is limited to the purposes disclosed in these Terms and our Privacy Policy, consistent with Google's API Services User Data Policy including the Limited Use requirements.

Informal resolution. Before initiating any formal legal proceeding, you agree to first contact us at legal@ottohq.app and attempt to resolve the dispute informally. We will use good faith efforts to resolve the dispute within 30 days.
Binding arbitration. If informal resolution fails, any dispute, claim, or controversy arising out of or relating to these Terms or the Service (except as noted below) shall be resolved by binding arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules. The arbitration shall be conducted in English, and the arbitrator's decision shall be final and binding.

We may impose usage limits, throttling, or restrictions to maintain service quality for all users. Excessive use that materially impacts other users may result in temporary restrictions.

Severability. If any provision of these Terms is found to be invalid, illegal, or unenforceable, the remaining provisions will continue in full force and effect.
Waiver. Our failure to enforce any right or provision of these Terms will not be considered a waiver of those rights. A waiver of any right or provision must be in writing and signed by an authorized representative of Otto AI, Inc..
