Frequently Asked Questions


How can I pay?

We support a variety of payment methods, including PayPal, credit card, and iDeal.


What happens when my prepaid period runs out?

Your experiment can still run but it will no longer collect data. It can still be used as a demo. Your data will be saved, also without an active prepaid experiment, as will your other materials. Accounts that have been inactive (with no logins) for one year after the prepaid period has run out may be deleted. You will be notified by this in advance by email.

Scripts that are shared in the Share Section or put up for sale in the Task Store will not be deleted and neither will the owner's account.


What happens when I purchase another plan while the current one is still running?

The new period of data collection will be added seamlessly to the end of your current period.


I need to show hours of high-definition movies for my research, how can I do that?

If you upload these videos to your account it is likely you will exceed the allowed transfer size. You can also serve your videos from YouTube, which does not use transfer GBs in your account. If this is not an option, contact us: We may make media transfer vouchers available if there is a demand for it.
