Lingmah is a vocabulary and English-learning app. We're here to help.
Subscriptions (Lingmah Pro, Battle, 4 Skills) are billed by Apple through your App Store account and renew automatically. To view, change, or cancel:
On your iPhone: Settings → [your name] → Subscriptions → Lingmah. Cancelling stops the next renewal; you keep access until the end of the current period. Deleting the app does not cancel a subscription.
If you reinstalled the app or switched devices, open any paywall and tap Restore Purchases to re-activate a subscription you already own.
Purchases are processed by Apple. Refund requests are handled by Apple at reportaproblem.apple.com. We're not able to issue App Store refunds directly, but email us and we'll help where we can.
You can permanently delete your account and personal data from inside the app: Profile → Settings → Delete account. This removes your profile and learning data. (Note: deleting your account does not cancel an active subscription — cancel that separately in your App Store settings.) You can also request deletion by emailing support@lingmah.com.
Sign-in uses a one-time code sent by SMS to your phone number. If the code doesn't arrive, check your signal, wait a minute, and tap resend. You can also use the app as a guest and sign in later from Profile.
