At the moment we do not have a way for you to temporarily pause or suspend your account. That said, you don't have to go through your potentials, and by virtue of you not going through them, Hinge will recognize that you've become less active and show you to fewer and fewer people. Moreover, the potentials that you haven't checked won't go anywhere.
We're looking at suspension options and we've got some ideas coming down the pipeline. Sorry that option isn't available for you yet.
In the meantime, here's a little hack: If you go into Preferences, you can set your criteria a very unlikely combination. I recommend setting your preferences for a person who is 7 feet tall within a 1 mile radius, with the Dealbreakers toggled on. This will ensure that you aren't shown to anyone and that no one is shown to you.
Please note that this will not pause your paid subscription if you have one. Your subscription is managed by Apple or Google and we don't have the ability to change your billing cycle.
