You can sign in to NoteAI using your Apple ID or Google account when those options are available.
To sign in:
Open NoteAI
Go to Settings
Tap Sign In
Select Continue with Apple or Continue with Google
Follow the on-screen instructions
Use the same Apple ID or Google account that you originally used for your NoteAI account. Using a different account or sign-in method may open a different NoteAI account instead of your existing one.
If your subscription or notes do not appear after signing in, make sure you used the correct account and then try Restore Purchase from Settings if needed.
