Write to support

This page answers the questions we are asked most often about the HD Melmods Sandbox Mod application. If your question is not covered here, email us — there is no support queue, no ticket number and no bot in between.

HD Melmods is an unofficial companion app. We are not the developer of Melon Sandbox and we cannot help with problems inside that game itself. For anything happening in the game rather than in our app, please contact its developer.


1. What to include in your email

You will get a useful answer much faster if your first message already contains these details:

  • Device and operating system — for example "iPhone 13, iOS 18.2" or "Samsung Galaxy A54, Android 14".
  • App version — open the app and go to Settings → Version; send the whole line, including the number in brackets.
  • What you did and what happened — the steps you took, what you expected, and what the app did instead.
  • A screenshot or screen recording, if anything is shown on screen. This is the single most helpful thing you can attach.
  • For payment issues — the store you paid through (App Store or Google Play) and the email address on that store account. Never send us card numbers; we do not need them and cannot use them.

2. Subscriptions and billing

Subscriptions are sold and charged by Apple and Google, not by us. That means the subscription itself is managed in your store account, and we cannot start, stop or change it on your behalf.

To view or cancel on iPhone or iPad: open the Settings app, tap your name at the top, tap Subscriptions, select HD Melmods and then Cancel Subscription.

To view or cancel on Android: open the Google Play Store, tap your profile picture, then Payments and subscriptions → Subscriptions, select HD Melmods and then Cancel subscription.

Cancelling stops the next renewal. It does not shorten the period you have already paid for — premium features stay available until the end of the current billing period. Deleting the app does not cancel a subscription.

A subscription renews automatically unless it is cancelled at least 24 hours before the current period ends. The price, the period and the renewal date are always shown on the purchase screen before you confirm.

3. Refunds

Because the payment is taken by the store, refunds are decided by the store as well. We are not able to issue one directly.

If you were charged twice, charged after cancelling, or charged for something you never received, email us as well. We will confirm from our records what your account actually received and reply with a short written statement that you can attach to your refund request.

4. Premium is missing after paying

This is almost always one of three things, and all three are quick to fix:

  • A different store account. A purchase belongs to the Apple or Google account that paid for it. Make sure the device is signed in to that same account.
  • The purchase was not restored on this device. Open the premium screen in the app and use Restore purchases. On a new phone this step is always required.
  • The payment is still pending. Some payment methods take a few hours to clear. If the store has not confirmed the charge yet, the app cannot unlock the features.

Still missing after all three? Send us the details together with your store receipt (Apple emails it to you; Google Play shows it under Payments and subscriptions → Budget and order history) and we will unlock it manually.

5. Mods will not download or install

Work through this list in order:

  • Is Melon Sandbox installed? Our mods are files for that game. Without the game on the same device there is nothing for them to be installed into.
  • Is there free storage space? Large mod packs need room to unpack. Free up a few hundred megabytes and try again.
  • Is the connection stable? A download interrupted halfway leaves an unusable file. Switch between Wi-Fi and mobile data and start the download again.
  • Did you grant the file permission? On Android the app needs permission to write the mod into the game's folder. Check it under Android Settings → Apps → HD Melmods → Permissions.
  • Try one other mod. If everything else installs, the problem is that single file — tell us which one and we will repair or remove it.

6. Your account and your data

Much of the app works without an account. If you created one, you can ask us at any time to:

  • Delete your account and the personal information attached to it — request deletion. Write from the email address on the account, or tell us which address it uses. We complete deletions within 30 days and confirm by email when it is done.
  • Receive a copy of your data, or have it corrected — send a data request.

Deleting your account does not cancel a paid subscription, because the subscription lives in your store account. Cancel it in the App Store or Google Play as described in Section 2, otherwise it will keep renewing.

What we collect and why is set out in full in our Privacy Policy.

7. Reporting a bug or a broken mod

Bug reports are welcome and they are read. Send a bug report with the details from Section 1, and tell us whether the problem happens every time or only occasionally.

If a specific mod is broken, crashes the game or is not what its preview shows, include its name and, if you can, a screenshot of its page in the app. Mods reported as broken are checked and either fixed or taken down.
