The current version of the free version of the app can be used indefinitely. However, there is no right to this sales concept remaining in place indefinitely.

This app is completely ad-free. User data is not sold to business partners. This means that the sources of income that have become common in the app sector are no longer available. The author of all4hue consciously decided against these two financing methods. The financing of the time-consuming and costly further development of the app and above all the continuous provision of support for user inquiries is therefore be made via one-time in-app purchases. A cost-intensive subscription model, as with competing apps, is not offered. The in-app purchases were intentionally divided into different packages so that the main program can be offered as cheaply as possible. Compared to simple apps, such as shopping lists or note management, all4hue has many complex functions that are difficult to implement, which is why the prices may seem comparatively ambitious for one or the other user. Since the introduction of all4hue in 2015, however, more than 200 functional updates have been provided by all4hue and the author continues to work tirelessly with great commitment to continue offering all4hue as the third-party reference app for Philips Hue.

• Android: During installation of the app, it is automatically checked which packages have already been purchased and the recognized purchases are automatically made available on the device. If the app is already installed on your device, go to the "Activations" section to manually trigger the recognition process of existing purchases.
• iOS/macOS: During installation of the app, it is automatically checked which packages have already been purchased and the recognized purchases are automatically made available on the device. If the app is already installed on your device, go to the "Activations" section to manually trigger the recognition process of existing purchases.

• The sales concept is designed in such a way that the free version can be tested indefinitely. Only after checking the free version is it recommended to activate additional features. So users can be sure that they are not buying a "pig in a poke".
• Unfortunately, there are a significant number of users who would take advantage of a refund to use the app they purchased to fully configure their Hue Bridge and then request a refund.

Unfortunately, it is neither legally nor technically possible to recognize and use activations of one operating system on another. For example, if you have purchased an activation on Android, this activation cannot be used on Windows 10 or iOS for technical and legal reasons. You have to do the activation again there.
