Purchasing options for Freedome (License Length, Terms, Platforms and Support)

I purchased a 1 month subscription through the Google Play Store. I figured it was applicable for 1 month (30 days) for up to 2 devices (in my case it would be an Android Phone, and 2 Windows devices). I was dismayed when it was only valid for Android devices during that period. I forgot to read the fine print. (The last time I used Freedome was months ago but stopped due to it crashing or not updating, until the recent Google Play Store purchase).

I then found out that if purchased through the website, it is 3 devices on any platform), but you must purchase a minimumlicense period of 1 year.

Are there more flexible and affordable options?

I have some feedback (constructuve) for F-Secure staff if they would like it on licensing/purchasing choices. Just offering it. I don't want to make a fuss, overall it is a relatively good product.

Edit: Platform

Android 5.1.1 (to be Upgraded to 6.0.1 by Carrier soon I hope)

Device: Samsung Galaxy S5 (SM-G900T)

Windows 10 Home 64 bit build 10586.164 (1511)
