The Coolmuster Android Backup Manager giveaway gives you a 1-year license, normally $19.95, for free, and I tested it on version 4.0.11 on Windows 11 on November 11, 2026.
Most readers need one thing from this offer: the unlocked Restore button. The free trial can back up your phone, but it locks restoring. Therefore, a backup you cannot restore is only half a solution. Below, I show how to claim the license, how to register it, and what the tool does not back up.
Coolmuster Android Backup Manager 1-Year License
Submit your name and email on the official page. The license code appears in a pop-up, and you register it inside the app.
Offers can end without notice. Both buttons go to Coolmuster’s official pages.
What Is Coolmuster Android Backup Manager?
Coolmuster Android Backup Manager is a Windows program that copies data from an Android phone to your PC and restores it with one click. It works locally, so your files do not pass through a cloud account.
According to Coolmuster, it covers eight data categories:
- Contacts
- Text messages (SMS)
- Call logs
- Photos and videos
- Music
- Documents and books
- User apps (.APK installers)
Why the Free Trial Is Not Enough
In my test, the trial let me back up phone data but locked Restore phone data. After registering the giveaway license, both options became available. As a result, the license matters most on the day you need to bring a backup back.
How to Get the Coolmuster Android Backup Manager Giveaway License
Follow these five steps in order. Use the same email address from Step 1 until the very end.
Step 1: Submit the Official Giveaway Form
Open the official giveaway page. Then fill in your name, a working email address, and the captcha, and click Submit.
Step 2: Copy the License Code From the Pop-Up
Right after you submit, a pop-up shows your personal license code. Copy it immediately, and save it next to the email address you used.
Step 3: Install the Official Windows Setup
Download the installer with the button in the box above, then run it. Click Next through the wizard until setup finishes.
Step 4: Register the License Inside the App
Open the program and click the key icon (1), then the Register button (2). Next, type your giveaway email (3) and paste the license code (4). Finally, click Register (5).
The most common cause is a different email address. Register with the exact same email you typed on the giveaway page, with no spaces before or after it. Also paste the code instead of retyping it.
Step 5: Confirm the 365-Day Subscription
After registration, the window shows a 1 Year Subscription from 2026-11-11 to 2027-11-11, with 365 days remaining. The Trial vs Full table also marks Restore as available.
How It Works: USB Cable vs Wi-Fi
The main screen asks you to connect your phone in one of two ways. In this test, I verified the registration and the unlocked features. Backup speed depends on your phone, cable, and data size, so I do not quote speed numbers.
- USB cable: the better choice for large photo and video libraries. However, you must enable USB debugging on the phone first.
- Wi-Fi with a QR code: useful when no cable is nearby. It uses Coolmuster’s companion app on the phone.
Selective Restore
You can restore chosen categories instead of the whole backup. According to Coolmuster, restoring does not overwrite existing data on the target phone unless you tick the option to clear it. Even so, test on a spare phone first if your data is important.
What It Backs Up and What It Does Not
It saves app installers, not app data. The tool copies the .APK files of your apps. It does not copy logged-in sessions or internal chat databases such as WhatsApp. If you need those chats, read our Coolmuster Android WhatsApp Recovery Giveaway guide.
It prevents loss; it does not recover deleted files. The program copies what exists on the phone today. Therefore, if you already deleted contacts, SMS, or photos before making a backup, try Coolmuster Lab.Fone for Android instead. iPhone users should read our Coolmuster iPhone Data Recovery review, and iCloud users can see the Coolmuster iCloud Backup Recovery guide.

Final Verdict: Who Should Claim This Giveaway?
