What changed in AI vendor terms the week of September 21–27, 2026?

data sharing improved from high/sale or sell to medium/third party or vendor sharing.

“If you are an agent making a request on behalf of a consumer, we reserve the right to take steps to verify that you are authorized to make that request, which may include requiring you to provide us with written proof such as a notarized authentication letter or a legally sufficient power of attorney signed by the data subject pursuant to California Probate Code sections 4121 to 4130, or other written authorization acceptable to us. We also may require the consumer to verify their identity directly with us where permitted. We are not responsible for the security risks of this or any other arrangements that a consumer may have with an agent. For clarity, this is not permission for any user to disclose their login credentials to an agent or any third party. Such disclosure is prohibited and is not required for an agent to make requests under this Notice.”

data sharing worsened from medium/third party or vendor sharing to high/sale or sell.

“To our knowledge, we do not “sell” or “share” the personal information of individuals under 16 years of age.”

model training improved from high/training permitted to medium/training with opt out.

“(c) Opt-Out; Withdrawal. Except as provided in Section 3.6 with respect to Forge Content while Bolt Forge is enabled, you may opt out of the uses described in Sections 3.5(a) and 3.5(b) at any time, free of charge and regardless of your plan, through your account settings or by contacting privacy@stackblitz.com . Upon receipt of an opt-out request, Stackblitz will promptly place the account on a suppression list designed to prevent the selection of that account’s Bolt Model Development Content for new model-training runs or new licensed datasets while the request is being processed. Stackblitz will complete implementation of the opt-out across applicable systems as soon as reasonably practicable and in any event within fifteen (15) days after receipt of your request. After the opt-out is effective, Stackblitz will not use your Bolt Model Development Content for new model development under Section 3.5(a) or include it in datasets newly licensed under Section 3.5(b). An opt-out or withdrawal does not, by itself, unwind processing completed before the request, models already trained, or datasets already delivered to licensees, but nothing in this Section limits any right or remedy available under applicable law or any action Stackblitz is required to take under applicable law. This Section does not limit the operational license in Section 3.2. No opt-out is required for a Restricted Region Account; see Section 3.5(e).”

model training improved from high/training permitted to low/no training claim.

“4.2 License to Customer Materials and Customer Created Content: The Services may enable Customer to submit and upload Customer Materials to the Services. Customer hereby grants Colossyan a worldwide, royalty-free, fully paid-up, and sublicensable license to display, host, copy, use, process, edit, modify and reproduce (in any form) Customer Material for the sole purpose of providing and maintaining the Services to Customer. Colossyan will not use, and will not permit any third party to use, the Customer Materials to train any AI model or algorithm, with the sole exception that, solely to the extent necessary to provide the Services, Colossyan may use Recordings to train the AI model that creates and operates Customer’s Custom Created Avatar. Such AI model is exclusively used by Colossyan to provide the Custom Created Avatar for Customer, is not used for any other purpose and will be deleted by Colossyan within a reasonable period after the expiration or termination of the Agreement.”

data sharing worsened from medium/third party or vendor sharing to high/sale or sell.

“We never sell your data. It's simple: Your personal information and calls are not for sale. Ever.”

model training improved from high/training permitted to medium/training with opt out.

“In addition, if you are on a Hobby plan or trial Pro plan, you agree that we may use Your Content to train our artificial intelligence (" AI ") and machine learning models, and we may share Your Content with third parties for the purpose of developing and improving their products, including training and improving their AI and machine learning models (collectively, " Model Training "). If you are on a paid Pro plan, Model Training is not enabled by default and you may opt in to Model Training. You may opt-out of Model Training at any time by adjusting your Team account settings or by upgrading to an Enterprise plan.”
