Do I need a subscription to run Kaleidoscope?

Kaleidoscope 4 is a subscription-based product. An active subscription is required to use the app. Once the subscription has ended, you can no longer use Kaleidoscope 4.

If you own a license to Kaleidoscope 3 or Kaleidoscope 2, you can use that for as long as you like, even after having been subscribed to Kaleidoscope 4. Contact us if you require help retrieving your previous license.

How long does a subscription run?

A subscription is active once you purchase a yearly or monthly plan. By default, it will renew automatically. It ends after being canceled, either by you or by a repeatedly failing payment. You can cancel your subscription at any time.

What happens when I cancel my subscription?

From the moment you cancel until the end of the period (one month or one year from the start/renewal), you can still use Kaleidoscope 4.

Can I disable auto-renewing?

You can purchase a plan and then immediately cancel it. This will give you access to Kaleidoscope 4 for the entire period, but the subscription will not automatically renew at the end of that period. Then, you are free to purchase a new subscription at your convenience.

Is there a one-time purchase option for Kaleidoscope 4?

Kaleidoscope 4 is a subscription-based product and there is no one-time purchase.

Can I use Kaleidoscope 4 and Kaleidoscope 3 at the same time?

Let us know why would you want to do that.
