(1) Are you planning on having support for more than 5 devices at a future point?
5 devices is what we estimate 1 user has (avg max). If there is demand, we will definitely add a plan to support more devices (or users).
(2) Will you have any features to support parents protection of their children?
We already collect NSFW filter lists to be activated in the settings. Otherwise such features are tricky, as we need to start protecting against the person in front of the device, which is very hard. If you have suggestions, please share!
(3) How easy is it to integrate Safing into a home security stack, or an enterprise security stack?
Can you elaborate on what exactly you have in mind? We don't offer any integrations with other system out of the box yet. We have APIs though that you can use.
(4) Have you considered a one-time unlimited buy-in level in lieu of monthly?
We had a couple lifetime plans on our Kickstarter (years ago). Right now, we don't have any plans for this. You can pay in advance though - up to 4 years.
(5) Is this coming for iOS & MacOS?
Yes. Or, at least we will attempt. Going to be "fun" if Apple continues their locking down strategy. Maybe the EU will force them to open up until then. Expect at least 1-2 years for this to land though.
