| Training detail | The consumer FAQ, last shown as May 12, 2025, says SpaceXSI may use your content and interactions with Grok, including prompts, searches, and other materials you submit, along with Grok's responses, to train models, and that you control this in settings. The pages we read do not explicitly say whether Improve the Model is on or off when you first create a logged-in account. They do say that if you use Grok without logging in, where that is permitted outside the EU and UK, you will not have an option to opt out of model training. The same FAQ and the Enterprise FAQ say SpaceXSI does not use content from business and enterprise customers to train models, except that the Enterprise FAQ allows an optional trade of free credits for permission to train. Grok on the X platform is governed by X's privacy policy and terms, not this consumer policy. | The data-collection article says some data may be used to train AI models unless you opt out, and that AI data retention is enabled by default for Free, Pro, and Max. | The enterprise terms say Perplexity shall not use customer content to train, retrain, or fine-tune generative models, and shall not authorize third parties to do so. The help center says enterprise data is never used to train or fine-tune Perplexity's models. |
| How to opt out | On grok.com, open Settings, then Data, and deselect Improve the Model. In the Grok mobile app, open Settings, then Data Controls, and deselect Improve the model. The consumer FAQ says this applies to new conversations. Private Chat, where available, is also excluded from training; turn it on with the ghost icon. Even after you opt out, voluntary feedback such as a thumbs-up or thumbs-down may still be used for training. Unauthenticated use outside the EU and UK has no opt-out. If you use Grok on X, the consumer FAQ points you to the X Help Center instead. | In account settings, open Preferences and turn off AI data retention. Perplexity says previously collected training data cannot be removed, and the setting applies to that user only. | No opt-out is required. If the organization downgrades to a Free or non-Enterprise plan, Perplexity says the consumer default applies and someone must opt out manually. |
| Data retention | Logged-in users can keep conversation history until they delete it. If you delete conversations or your account, or if you use Private Chat, the privacy policy and consumer FAQ say the data is deleted from SpaceXSI systems within 30 days, unless it must be kept longer for legal, compliance, or safety reasons, or has been de-identified or pseudonymized and disassociated from your account. The privacy policy, last updated October 27, 2026, does not state one retention period for ordinary saved chats you have not deleted. For the API, the security FAQ says inputs and outputs are stored encrypted for 30 days by default, or not persisted if the team enables Zero Data Retention. | Unknown for a single chat-storage period. The article says opting out stops later training use, and that data may still be processed to run the service. | Uploaded files are retained for 7 days. Organizations with 50 or more Enterprise Pro seats, or one Enterprise Max seat, can set a custom retention period and force deletion. A lapsed subscription does not, by itself, switch the data into training. |
| BAA / HIPAA | No | Unknown | Unknown |
| BAA detail | The consumer privacy policy and terms do not offer a business associate agreement for personal Grok accounts. The Enterprise FAQ and the API security FAQ say SpaceXSI can support a customer's HIPAA obligations under some circumstances, and they point businesses to a BAA questionnaire. The API product page describes the enterprise API as HIPAA eligible, with a BAA available. That is not a consumer-plan offer. | The consumer help article does not mention a business associate agreement. | The enterprise terms incorporate a data processing addendum. They do not mention HIPAA or a business associate agreement in the sections we read. |
| Certifications | Unknown | Unknown | Unknown |
| Enterprise and admin controls | This draft is for the personal Grok app and grok.com, not for a Business or Enterprise workspace. Consumer terms say that if you sign up with a work email, your account may be linked to your organization's Grok Enterprise subscription, and an admin may access, monitor, and control it. Grok Business and Grok Enterprise, described on the business product page, the December 30, 2025 announcement, and the Grok.com user guide, are separate workspaces. Those pages and the consumer and enterprise FAQs say business and enterprise customer content is not used for training, with an Enterprise FAQ exception if the customer agrees to training in exchange for free credits. Business and Enterprise listings include no-training, team and seat management, and SOC 2. Enterprise adds custom SSO, SCIM, custom data retention, and, in Enterprise Vault, customer-managed keys and an isolated data plane. API customers can use a US regional endpoint and optional Zero Data Retention, which turns off features that need stored data. Authorized personnel may still review data when legally required, and automated classifiers may run for safety. A separate Grok Business or Grok Enterprise directory entry would be the cleaner way to rate those plans, similar to how ChatGPT is split. Certifications: Unknown for the consumer app. The API product page and API security FAQ say SpaceXSI is SOC 2 Type 2 compliant, and the Grok Business page also lists SOC 2 Type I and Type II. The pages we read do not say that certification covers the personal Grok app. | The opt-out is per user. Organization-wide retention is described for Enterprise plans, not for Free or Pro. | Admins on qualifying seat counts can set retention and force deletion. User content in a workspace is not visible to other members unless the product is used to share it. Marketing use of contact details is described separately and does not include customer content. |
