They can, but only if you don’t log in for a full year. If your account remains inactive for 12 months, it will be closed automatically, and any unredeemed CowCoins will be permanently lost.
The good news? Staying active is simple. Just log in at least once every 12 months to keep your account (and your CowCoins) safe. You can hold onto your rewards for as long as you like, as long as you remain active.
Please note that CashCow reserves the right to update its reward expiration policy at any time. Should any changes occur, all users will be notified in advance through official communication channels. However, once rewards expire, they may be removed from your account and cannot be refunded or reinstated.
