If you use the app regularly, your kicks will never expire. Kicks will only ever expire due to extended inactivity. We reclaim kicks from accounts that have been inactive for 6 months or longer. We always attempt to send an email to your Shopkick-registered email address first (if you have provided one), letting you know that your kicks will be reclaimed unless you log back in by a certain date. If you cannot log into your account from a Shopkick-compatible device within a 6 month period, please contact our support team.
