You can use Grok to research products and prepare a cart without typing card details into chat. Keep passwords, card numbers, security codes and one-time codes out of ordinary prompts; take control for authentication and payment confirmation; and inspect the merchant’s checkout before submitting anything. Grok’s documented Allow/Deny step and Link payment flow do not establish that card details are hidden from Grok, Link or the retailer.
Keep sensitive credentials out of ordinary chat
SpaceXAI’s consumer privacy policy asks users not to include personal information in prompts, while noting that it cannot control what users provide. The policy applies to direct use of Grok websites and apps; access through a third party can be governed by that service’s policy instead. Read SpaceXAI’s Privacy Policy.

For shopping, ask Grok to research products, compare options or prepare a cart, but set a clear boundary: it must not submit an order, purchase anything or save payment details without your approval. SpaceXAI’s Grok Bot guidance recommends explicit boundaries for purchases and other consequential actions.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Do not type card numbers, security codes, passwords, passkeys or one-time verification codes into ordinary chat.
- When authentication or a payment confirmation is required, take control of the computer and enter the information through the user-facing step.
- Do not assume every field in a checkout page is covered by a secure-secret process. The documented masked-secret behavior applies to a supported secure-secret request, not ordinary chat or every checkout field.
SpaceXAI’s guidance says the Bot should hand control to the user for passwords, passkeys, two-factor codes, CAPTCHAs and payment confirmations, and says not to send a password or one-time code in ordinary chat. See Grok Bot’s approvals, security and privacy guidance.

Review the Link approval step yourself
SpaceXAI’s changelog documents a purchase flow in which a card displays the amount and lets the user Allow or Deny the purchase; Link then completes payment. A separate changelog entry says the “Pay with” option can select a saved card from the user’s Link wallet. These details describe an approval and payment sequence, not which payment fields Grok Bot, Link or the retailer can see.
- Before approving, check the merchant, item, amount, shipping details and selected payment method on the purchase screen.
- Choose Allow only if the details match what you intend to buy; otherwise choose Deny and correct or abandon the order.
- Complete any payment confirmation yourself through the presented user-facing step.
The documented approval screen is not evidence that Link masks a card number from the merchant or that Grok Bot cannot access payment-related information. The reviewed product materials do not enumerate which transaction fields each party receives. See the Grok Bot changelog.

Check checkout forms before sharing contact details
A merchant may need an address or phone number to fulfill an order. Grok Bot documentation says it can present forms one step at a time in chat and fill a user’s answers into the web page. That convenience does not establish that the merchant receives less information than if you filled in the form directly.
- Confirm that the page is the merchant you intended to use before answering.
- Read each field and provide only what is needed for the order.
- Inspect the completed checkout page before submitting it, including the shipping destination and contact details.
The same documentation describes browser use of a hardware security key such as a YubiKey when the setting is enabled and each use is approved. A security key can help protect account sign-in; it does not conceal checkout information from a merchant. Grok Bot form and security-key guidance.

Use the privacy policy for the Grok surface you are using
Check whether you are using Grok directly, through X, or inside another company’s app. SpaceXAI’s consumer policy says third-party use is governed by that service’s policy; it specifically says Grok on X is covered by X’s privacy policy and terms. The policy also points users in the European Economic Area, United Kingdom and Switzerland to a regional addendum.
SpaceXAI’s consumer terms say some features may take autonomous actions, including browsing the web and interacting with third-party services, including financial institutions. They also describe circumstances in which X account details and Grok-on-X conversation history may be brought into a SpaceXAI account when a user connects with X credentials. Review the terms and the applicable service policy before connecting accounts or authorizing actions. SpaceXAI Consumer Terms of Service.

Do not confuse Grok Bot checkout with Gopuff’s Go assistant
Go is a shopping assistant inside Gopuff’s own app, powered by Grok models. Gopuff’s description says it can personalize carts using prior preferences and external signals. That is a separate shopping product, not evidence about Grok Bot’s Link checkout or a way to reduce payment-data sharing. Its published description does not establish a privacy comparison with the Grok Bot flow. Gopuff’s description of Go.

The official materials establish that Grok Bot can request user approval for a purchase, show an amount, and use Link to complete payment, including a saved Link wallet card selection. They do not establish merchant-side card masking or specify exactly which payment credentials and transaction fields are visible to Grok Bot, Link or the retailer. If limiting disclosure is important, review the retailer’s checkout and privacy terms as well as the policies for the Grok service and payment method you use. Do not treat an approval prompt as a guarantee of anonymity or concealment.
