Hey @Noor_XD
I saw your post and make a little extension for your help.
com.glich.onlinevalidation.aix (8.6 KB)
(I haven’t test it 
)
How Users Will Use It in Kodular
Drop extension
On Screen Initialize → SetDurationHours(24)
Call → CheckValidation
Then handle events:
- OnValid → allow app
- OnExpired → close or lock
- OnTampered → block
- OnInternetRequired → show message
Features (short)
Uses real internet time (Google server date header)
Anti-tamper detection (manual time change, rollback, timezone tricks)
Auto expiry from first launch (24h / 7d / 30d / custom hours)
Works offline temporarily with forced periodic online check
Persistent storage — remembers state across app restarts
Simple events: Valid, Expired, Tampered, InternetRequired
