Unfortunately, there is no option to pause your subscription at Ahrefs.
Instead, you can cancel your subscription and re-subscribe when you're ready to join us again (be sure to click both fields shown on below screenshot to enable "Cancel subscription" button):
Cancellation takes effect at the end of the current paid period – after which, your account will be downgraded to our free AWT plan.
If you have any questions or issues with cancellation, please contact us at support@ahrefs.com or drop us a note in a live chat.
