Frequently asked questions
Everything you need to know
Can I unlock all paid wallpapers with one plan?
Choose a Weekly, Yearly, or Lifetime plan and unlock instant access to every premium wallpaper — from stunning Mobile designs to breathtaking 8K Desktop backgrounds.
Can I get a refund if I change my mind?
Unfortunately, we do not offer refunds as you gain immediate access to paid wallpapers upon purchase. We kindly ask you to carefully examine the paid wallpapers before making a purchase decision.
Are future updates included with paid plans?
We add fresh content every day — at least 3 free and 3 Pro wallpapers. With a Weekly or Yearly subscription, you’ll enjoy full access as long as your plan is active. And with Lifetime, every wallpaper is yours forever.
Do you offer any discounts?
Our app supports Purchasing Power Parity (PPP), which means plan prices are fairly adjusted for each country — making premium wallpapers accessible to everyone, everywhere.
May I use your wallpapers for business or projects?
All of our wallpapers are unique and created by our talented team. Please note that they are not permitted for commercial use. If you would like to use them for your project, kindly reach out to us via email. Also, if you notice our wallpapers inside a different app or a website, please send us an email about it. Thank you!
