Yes. All Streamline subscriptions renew automatically at the end of each billing cycle (monthly or annually, depending on your plan).
You can cancel your subscription at any time from your Account Settings. Once canceled, your subscription will remain active until the end of your current billing period, and you won't be charged for the next renewal.
What happens to the assets I've already used?
Assets that you downloaded and used while your subscription was active are covered by a lifetime license. You can continue using those assets in your existing and future projects, even after your subscription ends, as long as your usage complies with our license terms.
However, assets that you downloaded but never used during your active subscription are not covered by the lifetime license. To use those assets in a project, you'll need to have an active subscription at the time you first use them.
Note: After your subscription expires, you won't be able to download new assets, access updates, or use previously downloaded but unused assets until you renew your subscription.
