Storage for Contact Form 7 is a free and open source plugin licensed under GPL — you’re free to use it on any number of sites, share with friends and learn from it. We charge a fee only to support the continued development and updates.
If for some reason you’re unable to buy the plugin, we would rather provide you with a free copy instead of having to use a “nulled” version which might have been modified to include malicious code.
Please reach out to support@preseto.com and we’ll send you a copy.
