A free trial is a promotional offer that allows customers to use a product or service for a limited time without charge. This period typically lasts from a few days to a month, giving users the chance to evaluate the features and benefits before committing to a purchase. Free trials are common in software, streaming services, and subscription-based products. During a free trial, users can access the full functionality of the product, but they may need to provide payment information upfront. If they do not cancel before the trial ends, they will be automatically charged for the subscription, making it important to keep track of the trial period.
