How can we help?

First, try closing the app completely and reopening it. If it keeps crashing:

1. Go to your phone's Settings → Apps → Math Drill → Clear Cache
2. Restart your phone
3. If the issue persists, uninstall and reinstall the app from Google Play (your data may be lost)
4. If it still crashes, use our support form with your phone model and Android version

Open Math Drill → go to the Stats tab → tap "Upgrade to Pro". On the upgrade screen, scroll down and tap "Restore Purchase". Make sure you are signed in to the same Google account you used when you originally purchased Pro. Restore is free and unlimited.

This can happen if the purchase confirmation was delayed. Try the following:

1. Close the app fully and reopen it
2. Go to Stats → Upgrade → "Restore Purchase" to re-confirm your purchase
3. Make sure you have an internet connection when restoring

If ads still appear after restoring, please contact us via the support form with your order number from Google Play (found in your Google account → Payments).

Unfortunately, progress data is stored locally on your device and is not backed up to any cloud server. When you uninstall the app, this data is deleted. We are planning to add optional backup functionality in a future update. Your Pro purchase however can always be restored — it is tied to your Google account, not your device.

Google Play allows refund requests within 48 hours of purchase. To request a refund:

1. Open the Google Play app on your phone
2. Tap your profile icon → "Payments & subscriptions" → "Order history"
3. Find the Math Drill Pro purchase and tap "Request a refund"

After 48 hours, refunds are at Google's discretion. For special circumstances, you can also contact us via the support form.

We work hard to ensure all answers are accurate, but mistakes can happen — especially in topics like fractions or negative numbers where rounding may vary. If you believe you've found a wrong answer, please use the support form with the specific question and topic. We'll verify and fix it in the next update.

Go to the Settings tab → scroll to the General section → look for the Language option. Currently English and Hindi are supported. More languages are coming soon.

We love suggestions! Use the support form below and describe what you'd like to see. Popular requests get added in future updates. You can also leave a review on Google Play — we read every single one.

Math Drill is designed for smartphones (portrait mode). It will run on tablets but the layout is optimised for phones. Tablet-optimised layout is on our roadmap.
