Pricing and Payment FAQs
Can I get a refund if I am not satisfied?
We are committed to our clients’ satisfaction and therefore offer a generous 30-day return policy. If you are not 100% satisfied with your purchase, we will be happy to provide a full refund of the purchase price.
What is automatic renewal?
ESET auto-renew ensures that your ESET licences and products are always up to date, providing continuous, year-round protection. We handle the billing and renewal for you using auto-renew.
By enabling auto-renew, you agree that at the end of your licence period, we will automatically renew your licence using the payment details currently on file.
We will inform you about upcoming auto-renewal and renewal prices 30 days before your renewal date (for annual subscriptions) and after your subscription automatically renews, we will email you the transaction details.
How do I cancel my subscription?
Auto-renew is continuous, unless you turn it off after your purchase, via your account. Turning off auto-renew will not cancel your licence – your ESET protection will continue until your licence expires. We will notify you before licence expiration so you may renew manually.
