13. Subscriptions, Automatic Renewal, and Cancellation

13.1 Automatic renewal. Chai Pro, CHAI MAX, and paid add-ons (such as voice, video, and image packages) are sold as subscriptions that renew automatically. Before you buy, we show you the price, the length of the billing period (for example, weekly, every four weeks, or every 52 weeks), and these renewal terms. By completing your purchase, you authorize Chai Research Corp. to charge your payment method that price, plus any applicable tax, at the start of each new billing period until you cancel. Each add-on is a separate subscription with its own price and billing period.

13.2 Free trials and introductory prices. If your plan starts with a free trial or an introductory price, it will automatically convert to a paid subscription at the regular price shown at purchase when the trial or introductory period ends, unless you cancel before then. To avoid being charged, cancel before the trial or introductory period ends.

13.3 Usage-based charges. CHAI MAX Auto is billed by usage at the rate shown at purchase (for example, a price per 1,000 tokens generated). Usage charges are billed in arrears for the usage you incur and renew with each billing cycle until you cancel.

13.4 Image and video generation. Pro subscribers can generate images and short videos of characters in chat. Generations beyond any credits included with your plan are charged per use at the rate shown before you generate (currently $0.12 per image and $0.22 per video), and you must confirm before your first paid generation. Per-use charges are billed to your payment method on file, either with your next invoice or when your unbilled usage reaches a threshold, whichever comes first.
  • Image Generation package: a yearly subscription that includes 50 image generations each week. Weekly credits reset every week and do not carry over.
  • Video Generation package: a yearly subscription that includes 150 video generations, granted once when the package is activated. Credits are not replenished when the package renews.
Generated images and videos are created by AI and may be inaccurate or unexpected. They are Contributions under Sections 6 and 7 and must follow the same rules.

13.5 Confirmation and reminders. After you subscribe, we will send you an email confirming your subscription, its renewal terms, our cancellation policy, and how to cancel. We will remind you about your subscription at least once a year. For subscriptions with a billing period of one year or longer, we will notify you 15 to 45 days before the subscription renews.

13.6 How to cancel. You can cancel at any time, online, without calling or contacting us:
  1. Go to your profile.
  2. In the subscription section, select "cancel plan" (or the cancel option next to the add-on you want to cancel).
  3. Follow the prompts to confirm.
When you start to cancel, we may show you an offer to keep your subscription. You do not have to accept it, and you can continue straight to cancellation. When your cancellation is complete, we will show you a confirmation that includes the date your access ends.

13.7 Effect of cancellation. Cancellation stops future renewals. You keep access to your paid features until the end of the billing period you have already paid for, and you will not be charged again. If you subscribed through a third-party store (such as the Apple App Store or Google Play), you must cancel through that store, and its billing and refund terms apply.

13.8 Refunds. Except where required by law, payments are non-refundable and we do not provide refunds or credits for partial billing periods or unused features. If you believe you were charged in error, contact support@chai-ai.com and we will review your request.

13.9 Price and term changes. We may change subscription prices or renewal terms. If we do, we will notify you by email at least 7 days, and no more than 30 days, before the change applies to you. The notice will explain the change and how to cancel. If you do not want to accept the change, you can cancel before it takes effect.

13.10 Failed payments. If a renewal payment fails, we may retry the charge, and we may suspend paid features until payment succeeds or your subscription is cancelled.

14. Termination

This agreement is valid until terminated by Chai Research Corp. or by You. Your rights under this agreement will terminate automatically and without notice if You fail to adhere to any term herein. Upon termination, You shall immediately cease accessing and using the Service. Cancelling a paid subscription is covered by Section 13 and does not by itself terminate this agreement or Your account.

15. Third-Party Terms

Chai Research Corp. will comply with applicable third-party terms of agreement in the operation of the Service. When using the Service, You must also ensure compliance with any applicable third-party terms and conditions.

16. Intellectual Property Rights

Chai Research Corp. will be solely responsible for the investigation, defense, settlement, and discharge of any third-party claim that the Licensed Application or End-User's use of it infringes on the third party's intellectual property rights.

17. Applicable Law

This License Agreement is governed by the laws of the State of California, excluding its conflicts of law rules.

18. Miscellaneous

18.1 If any term of this agreement becomes invalid, the validity of the remaining provisions shall not be affected. Invalid terms will be replaced by valid ones that achieve the same primary purpose.

18.2 Collateral agreements, changes, and amendments are only valid if laid down in writing.

18.3 Chai Research Corp. has no tolerance for objectionable content or abusive users. Users posting objectionable content or being abusive may be banned from the app without prior notice.
