How to detect if a user has already used the free trial?

[wspirin]

Hi! 👋

I’m building a React Native app using expo-iap, and I’m not sure how to properly detect if a user has already used their free trial period.

In my app, I show two different screens depending on the trial status:
• One for users who haven’t started the trial yet,
• And another for users who already used the trial (and now need to subscribe).

The problem is:
👉 My app doesn’t have user registration or accounts, so I can’t check it on the backend side (no way to identify users via email or userId).

Is there any reliable way (via expo-iap or store API) to detect if the user has already used the trial on this device or with their store account (Google Play / App Store)?

Environment:
• React Native (Expo Bare Workflow)
• Library: expo-iap (latest)
• Platform: Android & iOS

Expected behavior:
I’d like to detect if a user has already consumed the trial before showing the trial activation screen.

Actual behavior:
There’s no clear way to determine if the trial was already used without a user account or backend.

Question:
Is there a built-in method, property, or recommended approach to check the trial usage status per store account?

You can't.
I did try to contact Google Play for help but they couldn't do anything about it.
