Installing the app, step by step
The warning shown when installing outside the Play Store isn't a danger signal — it's Android's standard notice. We'll walk you through why it appears, how to proceed, and how to confirm the file is genuine.
① Why does this warning appear?
Android asks for confirmation the first time you install an app from outside the store. It appears for everyone, regardless of the app's risk.
Every file has a tamper-check fingerprint (SHA-256). Compare it with the value on the download page to verify authenticity yourself.
The “allow from this source” permission you turned on for installing can be turned off again afterward. It's a temporary allowance you open only when needed.
② Installation steps
Choose the tab that matches your device.
Tap the file from your browser's download notification or a file manager.
Android asks once when you first install an app from outside the store. It's a standard safety step, not a danger signal.
It applies only to the browser or file manager you just used. Go back and the installation continues.
Once installed, tap [Open] to launch it right away.
This notice appears because the app is new and not yet registered with Google. If the fingerprint (SHA-256) below matches, the file is genuine and untampered.
Tap the file in the “My Files” app or the Samsung Internet download list.
Samsung devices manage install permission per app. Just allow the app you just used.
Turn on the toggle in Settings, then press Back to continue the installation.
It installs to your regular home screen, not the Samsung Secure Folder.
If One UI's Auto Blocker is on, you may need to turn it off briefly. You can turn it back on after installing and the app still works fine.
③ How to verify authenticity (optional)
Compute the fingerprint of your file and compare it with the SHA-256 value on the download page. If even one character differs, don't install — download it again. Downloads →

Does this warning mean the app is dangerous?
No. It's a standard notice Android always shows when installing apps from outside the Play Store. It's unrelated to the app's own risk, and you can verify authenticity yourself with the SHA-256 fingerprint below.
Why isn't it on the Play Store?
We distribute it directly to fully include advanced features that are hard to offer under store policies (e.g., how media is processed). In return, we publish a tamper-check fingerprint for every release.
Can I turn off “allow from this source” after installing?
Yes. After installing, you can turn off the permission and the already-installed app keeps working. You only need to allow it again the next time you update.
How do I enter the license key?
Run the app, create a request key on the license screen, and enter the key (or QR) issued on this site. The key is permanently bound to the one device that created the request key.
What if the fingerprint (SHA-256) doesn't match?
Don't install — download it again. If it still differs, the file is corrupted or came from an untrusted source, so download only from this site's download page.
Grab the latest version from the download page and give it a try.
