Questions
Is this legal advice?
No. Pixatom points out where a flow touches published rules, such as subscription and pricing rules, and names them so you know what to check. For a final view on compliance, ask your legal team.
Does it connect to Stripe or my billing system?
No. You describe the flow in plain words. Pixatom does not need access to your billing data or your code.
What if my flow is mostly on iPhone or Android?
Tell Pixatom where people subscribe. It checks app store rules as well as web flows and marks where a step has to hand over to Apple or Google.
