We have a formal end user license agreement, which you can read if you're really bored. What follows is an interpretation of how that license agreement applies in various scenarios.

Important note: The following applies to apps you purchase directly from us. If you purchase our apps through the Mac App Store, then you're subject to Apple's Mac App Store license agreement. We have no ability to do anything about Apple's policies; their store is their store.

Our app license is a perpetual license: Once you purchase an app from us, you own that version of the app (plus any updates released within at least the first year) forever. It is not a subscription; the app will work until/unless some future macOS update breaks it and we haven't released an update to address that breakage.

Your perpetual license also includes at least a year of free updates. After that year is up, there may be paid updates available for your app. If you purchase one of these paid updates, you will receive that update, plus any features released in prior updates, plus at least one more year of free updates. These are optional purchases, and won't affect the continued operation of the app you purchased. For more details on our paid updates plan, please read about our evolutionary app update model.

All of our products fall under one general license relative to usage. Here's how the licensing works; we think it's user-friendly and easy to understand. It's basically a "buy only one" license model, except in the case of possible simultaneous usage. There are three types of usage that need to be discussed:

If you use only one Mac: If you use just one Mac, then your Many Tricks' license is good for all users of that machine. So if your family is sharing a single Mac, you need only one Many Tricks license for each of our products, regardless of how many people are using them on that one machine.

If you use more than one Mac: If you use more than one Mac, and it's just you that uses it, then you also need just one license per Many Tricks app that you use. So if you want to use Witch on all seven of your Macs, go right ahead and do so -- you just need to purchase one license to cover all seven.

If you and others in your family use more than one Mac: You need only one license (for each of our apps that you purchase) to cover everyone in your family. What is a family? Relative to the licensing of our apps, our intent is that one license should cover a group of directly-related people living in one home, plus any children who may live elsewhere. But we'll leave the specifics up to you, instead of trying to define every permutation of a family.

Please note that our licensing is done on the honor system: Many Tricks does not track your usage of our apps or installations of our licenses. We simply trust our users to do the right thing.

To install your license on multiple Macs: Simply copy the license file to each Mac (to its Desktop, for instance) on which you'd like to use the app, and make sure the app is installed on that Mac. Then double-click the license file, and the app should open and show you as a licensed user. You can then delete the license file from the Desktop, as the app will copy it to the right location.

Enterprise use: If you are going to use Moom at a company, the same general rules apply: Regardless of how many Macs you personally use at home and/or work, as long as it's just you running our software, you need only one license.

If the app will be installed such that more than one user may use the app, or if you're buying for a number of users at your employer, then you need to purchase enough licenses to cover the expected number of users, even if they're all sharing one Mac (because these users would be licensed to use it at the same time on another Mac). Note, too, that we have generous multi-item discount pricing, and can work up a custom discount for even larger quantities.
