How to cancel Grok by mail
Get your account details together

Send the letter by certified mail
Post it by certified mail to Grok in Palo Alto, United States, using the exact address below, and note the tracking number.
Keep the proof of delivery
Keep the tracking record with your copy of the letter. If Grok bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Grok, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.
