You can get all the current and future NetGuard pro features (including updates) without Google Play services for the GitHub or F-Droid version by a one time donation of 1 euro or more. If you donate 5 euros or more, you are allowed to activate the pro features on all the devices you personally own, else you are allowed to activate the pro features one time only.

You can donate with PayPal or a credit card:

The development of NetGuard took more than 2,500 hours, so I think a donation of at least € 5 is not too much to ask for. I still want to donate less than 5 euros and I accept that I can activate the pro features one time only

Instructions about how to activate the pro features will be automatically sent to your (PayPal) email address.

PayPal donations are not possible from some countries, in these cases you can send money directly to marcel@faircode.eu.
