You can cancel your subscription, delete your account, and close your profile any time you wish - and the cancellation process depends on what sort of membership you have.
Free accounts can be closed at any time, and your profile suspended or deleted depending on whether you want to leave the platform temporarily or permanently.
If you have a premium membership, you can cancel at any time through the Account Settings section of your account and can continue to enjoy premium member access until the end of your subscription duration.
Should you decide to cancel a paid subscription towards the end of the billing cycle, you should cancel with your payment provider as well as with Flirt to ensure no further payments are taken.
