  • Do you offer support ?
    We offer nearly 24/7 technical support and help with installation.
  • What happens after I pay?

    You will get an email right after you pay with the source (packed version) + demo license + full document. You need to reply that email and give us your domain names corresponding with plan you purchased, we will give you license for registered domains (in 24 hours).

  • What's license file ?

    It’s a file that allows the script run and hosted on domains you have registered with us.

    Please save this file, do not lose it until expired.

  • What's different between 1 domain and unlimited domain ?

    1 domain: script will works when you open http://your-domain.com with this script embedded, but if you use this script for other domain by adding this code <script src="http://your-domain.com/pop.js"></script> to other domain, it will not works. If you're adnetwork, have to use unlimited domain.

    unlimited domain: script will works on any domain, just add <script src="http://your-domain.com/pop.js"></script> this code to any domain you want. But if you download pop.js and upload to other domain and use code like <script src="http://other-domain.com/pop.js"></script>, it will not works.

  • Can i modify this script ?
    Since 2.x, we don't provide raw source code any more, so you can't modify it. But we provide more APIs, you can use hooks to customize and integrate with your tracking system.
  • Can i have a trial before purchsae ?
    Sorry, we don't have any trial version yet. We already provide demo that you can test it on any devices you have before decide purchase or not.
  • Is possible to make pop under on page load, hover or unload ?

    There is no way to make pop under on page load (onload) event or before closing window (unload) or hover. It’s possible if you’re in before 2007.

    Pop under only works when you touch/click to page content.

  • Can i cancel recuring payment ?

    If you want to purchase only one year and don't want to renew it, you can cancel it after purchased. But next year if you want to use it, you have to purchase it again with price at that time (price may be changed)
