We encourage you to periodically review these Service Terms to be informed about your and Posit’s rights and obligations with respect to Posit AI.

Types and Ownership of Content. Any information you input into Posit AI, including your queries, or make available for analysis by Posit AI, is referred to as “Input Data.” Any information output by Posit AI in response to your Input Data is referred to as “Output Data.” Together, Input Data and Output Data are referred to as “Content.” You own and are responsible for the Content, including ensuring that it does not violate any applicable law or these Service Terms.

Use of Content by Posit. Posit will use Content to provide, maintain, develop, train and improve Posit AI, comply with applicable law, enforce these Service Terms, and keep Posit AI safe. In connection with the provision of Posit AI, Posit relies on third-party LLM providers, and your Content will be shared with such third-parties for processing Input Data and providing Output Data. Posit has in place a Zero Data Retention agreement with its LLM providers and, as a result, your Content will not be retained by such third-parties, and will not be used by such third-parties to train their models.

Opting Out. If you do not want Posit to use your Content to train its models, do not opt in to Help Improve Posit AI at the time of account creation. If you have opted in and later wish to opt out, please contact support.

Accuracy. Posit is working to make Posit AI accurate, reliable, safe, and beneficial. However, given the nature of AI and machine learning, use of Posit AI may result in inaccurate Output Data. As a result, when you use Posit AI, you understand and agree:

  • Output Data may not always be accurate. You should not rely on Output Data from Posit AI as a sole source of truth or factual information, or as a substitute for your own assessment and review.
  • You must evaluate Output Data for accuracy and appropriateness for your use case, including using human review as appropriate, before using or sharing Output Data from Posit AI.
  • You must not use any Output Data relating to a person for any purpose that could have a legal or material impact on that person, such as making credit, educational, employment, housing, insurance, legal, medical, or other important decisions about them.
  • Output Data does not represent Posit’s views. If Output Data references any third party products or services, it doesn’t mean the third party endorses, or is affiliated with, or is endorsed by, Posit.

Types of Accounts; Payments and Taxes; Refunds; Changes to Your Plan. Posit allows you to use Posit AI, without charge, as described on the free trial plan entitlements page (the “Free Trial”). One person may not maintain more than one free Posit AI account.

Posit also offers a paid plan under which you are provided a specified number of usage credits per month to be used in connection with Posit AI (the “Paid Plan”). In connection with Posit AI, the “month” begins on the day you sign up for the Paid Plan. For example, if you sign up on the 15th of a calendar month, the “month” will end on the 14th of the following calendar month. The details of each of the Free Trial and the Paid Plan are set forth on the Posit AI website at https://posit.ai. All Paid Plan purchases are final, and no refunds will be given for unused credits, unless otherwise required by law. Unused credits do not carry over from month to month (unless such credits were purchased in addition to the credits included in the Paid Plan).

For the Paid Plan, Posit AI is billed in advance on a monthly basis and is non-refundable. All Paid Plans will automatically renew each month unless and until you cancel your Paid Plan. To cancel your Paid Plan at any time, please visit https://posit.ai/billing. If we are unable to charge your credit card when you sign up for a Paid Plan, or upon the monthly renewal of any Paid Plan, we will suspend your usage of Posit AI until such time that the monthly fee has been paid.

All fees for Paid Plans are exclusive of all taxes. You are responsible for all applicable taxes and we will charge you for taxes when required by law.

You can cancel your Paid Plan at any time. Payments are non-refundable, except where required by law. If you cancel, your cancellation will take effect at the end of the billing month and you will be entitled to use Posit AI (subject to available credits) until the end of that period . These Service Terms do not override any mandatory local laws regarding your cancellation rights.

Price Changes. We may change our prices from time to time. If we increase our subscription prices, we will give you at least 30 days’ notice and any price increase will take effect on your next renewal so that you can cancel if you do not agree to the price increase.

Termination and Suspension. Posit has the right to suspend or terminate your account and refuse current or future use of Posit AI if you breach these Service Terms or any terms referenced in these Service Terms, or if required to do so by law. Posit may also suspend or terminate your account for non-payment, or if your usage of Posit AI is deemed likely to harm Posit, Posit AI users, or others.

Notifications and Service Messages. Posit may notify you via the email address associated with your account, within Posit AI, or on Posit’s website at posit.co.

Posit Intellectual Property Rights. All right, title, and interest in and to Posit AI is and will remain the exclusive property of Posit, including all intellectual property rights in Posit AI.

Posit disclaims all liability for, and is not responsible for, any harm to your computer system, loss or corruption of data, or other harm that results from your access to or use of Posit AI. WITHOUT LIMITING THE FOREGOING, POSIT EXPLICITLY DISCLAIMS ANY AND ALL WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT OF THIRD PARTY RIGHTS AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE. YOU ACKNOWLEDGE THAT USE OF POSIT AI MAY RESULT IN UNEXPECTED RESULTS, LOSS OR CORRUPTION OF DATA OR COMMUNICATIONS, PROJECT DELAYS, OTHER UNPREDICTABLE DAMAGE OR LOSS, OR EXPOSURE OF YOUR INFORMATION OR DATA TO UNINTENDED THIRD PARTIES.

POSIT MAKES NO WARRANTY THAT POSIT AI WILL MEET YOUR REQUIREMENTS OR BE AVAILABLE ON AN UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE BASIS OR THAT THE RESULTS THAT MAY BE OBTAINED FROM THE USE OF POSIT AI WILL BE ACCURATE OR RELIABLE OR THAT ANY ERRORS IN POSIT AI WILL BE CORRECTED. YOU ACCEPT AND AGREE THAT ANY USE OF OUTPUT DATA IS AT YOUR SOLE RISK AND YOU WILL NOT RELY ON OUTPUT DATA AS A SOLE SOURCE OF TRUTH OR FACTUAL INFORMATION, OR AS A SUBSTITUTE FOR PROFESSIONAL ADVICE.

Your Indemnity. You agree to indemnify, defend and hold harmless Posit and its officers, employees, directors, agents, affiliates, subsidiaries, successors and assigns from and against any and all third party claims, damages, liabilities, loss, government fines, costs and expenses (including reasonable attorney’s fees and litigation expenses), arising out of or related to any alleged or actual breach of these Service Terms (including the policies and terms referenced in these Service Terms), your use of Posit AI or your Content.

Limitation of Liability. POSIT WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES, INCLUDING DAMAGES FOR LOSS OF PROFITS, GOODWILL, USE, OR DATA OR OTHER LOSSES, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. POSIT’S AGGREGATE LIABILITY UNDER THESE SERVICE TERMS WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID FOR POSIT AI DURING THE 12 MONTHS BEFORE THE LIABILITY AROSE OR ONE HUNDRED DOLLARS ($100). THE LIMITATIONS IN THIS SECTION APPLY ONLY TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW.

Some countries and states do not allow the disclaimer of certain warranties or the limitation of certain damages, so some or all of the terms above may not apply to you, and you may have additional rights. In that case, these Service Terms only limit our responsibilities to the maximum extent permissible in your country of residence.

Governing Law. These Service Terms shall be governed by the internal laws of the Commonwealth of Massachusetts, U.S.A., without giving effect to principles of conflict of laws.

Binding Arbitration. If a resolution is not reached within thirty (30) days, all claims arising out of or relating to these Service Terms shall be finally settled by binding arbitration administered by the American Arbitration Association (“AAA”) under its Consumer Arbitration Rules.

Waiver of Class Action. THE PARTIES AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING.

Attorney’s Fees: Each party shall bear its own attorneys’ fees and costs, unless the arbitrator finds that either the substance of the claim or the relief sought was frivolous or brought for an improper purpose (as measured by the standards set forth in Federal Rule of Civil Procedure 11(b)).

You acknowledge and agree that any claim or dispute arising out of these Service Terms or your use of Posit AI must be brought by you within one year from the date the cause of action first accrued.
