BDG Win Install Checklist: 12 Checks to Run

Updated 8 October 2026 · 5 minute read

Before an app file goes on your phone, answer twelve short checks about the link, the file and what it asks for. The tool counts the passes, the problems and the checks still open, then lists what to do next. It never calls a file safe.

Tool · runs in your browserNothing is uploaded

Answer each check for the file in front of you. Nothing you tick is stored or sent anywhere.

Where the link came from. You reached the download from a page whose address you typed yourself, or from a link you can account for.

How to check this
  • Think back to where you first saw the link.
  • An ad, a comment, a group chat, a forwarded message, a video description or a message from a stranger does not count.
  • If you cannot remember, leave this open and go back to the page you started from.

How to check this
  • Press and hold the link and copy it instead of tapping it.
  • A link that ends in .apk, or a short link, hides the page you would want to read first.
  • Paste the copied link into the link checker and read the warnings.

The file

Why you want it. You want the app for a reason of your own. Nobody told you a file is needed to log in, claim a bonus or unlock something.

How to check this
  • Ask yourself who first said you needed a file.
  • Installing a file does not fix a login problem.
  • If the only reason is that someone said so, the honest answer is a problem.

What the file is called. Neither the file name nor the page that offers it uses the words mod, hack, unlimited, premium unlocked, predictor or cheat.

How to check this
  • Read the exact file name and the words on the page that offers it.
  • Those words promise something a file on your phone cannot deliver, because a file cannot change what an online service keeps on its own servers.
  • Files sold on those words usually do something else.

Who published it. A publisher’s name is given, and the same name appears on a second page that you reached by typing the address yourself.

How to check this
  • Look for a publisher or developer name on the page the file came from.
  • Look for the same name on another page you reach on your own, such as a store listing.
  • A name that appears in one place only proves nothing, because whoever uploaded the file typed it.

The file’s fingerprint. The publisher gives a SHA-256 fingerprint on a second page, and your file matches it.

How to check this
  • A fingerprint is a 64-character value worked out from every byte of the file.
  • Find one on a page you reached on your own, not beside the download link.
  • Work out your file’s fingerprint with the file fingerprint checker and compare the two.

What it asks for

Permissions. None of the permissions it asks for is one a game has no use for: reading texts, accessibility service, device administrator, notification access or display over other apps.

How to check this
  • A store listing or the publisher’s page may list the permissions. Check it if it does.
  • A file from outside a store has no listing, so the pop-ups and the Settings screens are your only preview. In that case leave this open.
  • Refuse any request for your texts or for accessibility each time it appears.

Payments. Nobody has asked you to pay, to send money to a person’s UPI ID or to share card or bank details, in order to get this file or unlock it.

How to check this
  • Check the page and any chat with whoever sent the file.
  • A fee, a deposit or a “verification payment” for a file is a trick, and so is a request to send money to a person’s UPI ID.
  • If the app later asks for card, bank or UPI details on screens of its own, stop and remove it.

Read more: After a scam

Play Protect. Play Protect is switched on, and it has not warned about this file.

How to check this
  • In the Play Store, tap your profile picture, then Play Protect, and check that scanning is on.
  • A warning is a stop sign, not something to tap past.
  • Do not switch Play Protect off to make a file install.

Read more: Checking an app file

Around the app

How it updates. You know how new versions arrive: through a store listing or the page you got the file from, not through links sent in chats.

How to check this
  • Ask where new versions come from.
  • An app that tells you to download and install another file, or a chat that sends “update files”, keeps asking you to leave the door open.
  • A web page saved to your home screen has no updates to manage.

Read more: Old and latest versions

Reviews. The reviews you can find are on a store listing or a page you reached yourself, and none describes lost money, locked accounts or surprise requests. This is the weakest check.

How to check this
  • Ratings and download counts on the page that offers the file are typed by whoever uploaded it.
  • Look for reviews on a store listing or a site you reached on your own.
  • Treat this as the weakest check, because reviews can be bought or copied.

Read more: Checking an app file

A way back. You have a screenshot of the page the file came from, and you know how to remove the app.

How to check this
  • Take a screenshot of the page and its address before you install.
  • To remove an app, touch and hold its icon and choose Uninstall, or open Settings, then Apps.
  • If you ever need to report a problem, the screenshot is your record.

Why twelve checks and not one

Any single sign can be made to look right. A fingerprint can be printed beside a swapped file, a short permissions list says nothing about behaviour, and reviews can be bought. The twelve checks cover different ways a file reaches a phone, so one faked sign does not settle the matter.

Nobody can see inside a file from outside, and this tool does not try. It works only from what you tell it. What comes back is a count of passes, problems and open checks, and the most it will ever say is that the risk looks lower.

First question: do you need a file at all?

At the time of writing (8 October 2026) the platform’s login and sign-up screens opened as web pages in the browser, with no file. Its home page had a download icon at the top right, which we did not tap, so we cannot say what it offers. It also showed an “Add to Desktop” prompt, which saves a shortcut to the web page and is not an app file. BDG Win app without an APK explains it.

So the third check, “Why you want it”, can end the search early. If the only reason is that someone said a file is needed, treat that as a problem. The app file guide covers the choice.

The twelve, in the order you meet them

A problem in eight of them is a reason to walk away from the file. A problem in the other four is something to put right.

A worked example: a file found by searching

You searched for the app, a download site came up, and its button starts a download. The tool opens on these answers:

  • Where the link came from: a problem. A search result is a page you cannot account for.
  • What the link points to: a problem. The button hands over an .apk the moment you tap it.
  • Why you want it, what the file is called, payments: fine. You want it for your own reasons, the name is plain and nobody has asked for money.
  • Reviews: a problem. The ones you found describe locked accounts.
  • The other six: not checked yet.

The tool counts 3 of 12 checks passed, 3 problems and 6 still open. One of the three, the source of the link, is a reason to walk away. Three passes do not outweigh it, so the tool says not to install the file, and to begin again from a source you can account for if you still want the app.

One check can end things alone. Say the sender tells you the file unlocks only after you pay a fee. Mark Payments as a problem, with three checks passed and eight open, and the tool counts 1 problem that is a reason to walk away. Its advice for that check starts: pay nothing and stop. If money has already gone, the next steps after a scam give the order.

Not checked is not passed

An open check counts as open, never as passed. Take permissions. A file that did not come from a store has no listing, so there is no list to read beforehand. The pop-ups and the Settings screens are your only preview, and what to say no to lists the requests. Leave the check open until they appear, and say no each time an app asks to read your texts or to use accessibility. A game has no use for either.

Where the checklist stops

It cannot open a file, so every answer is yours to give, and a careless answer gives a careless result. It cannot judge whether a publisher is honest or whether an app will accept your account. Play Protect, when it is switched on, does its own scanning. The list is a second layer beside it, not a replacement for it.

Two checks have tools of their own. Check 2 is a job for the link checker, and check 6 for the file fingerprint checker. A file will not fix a login problem, so if that is your real trouble, the login troubleshooter asks the questions instead. More tools are listed on the tools page.

Common questions

What if every check passes and I still feel unsure about the file?

Listen to that. Twelve passes lower the risk and do not remove it, because nobody can see inside a file from outside, and every sign on the list can be made to look right. If all you want is an icon on your home screen, a web page can be saved there, so you can skip the file.

Which of the twelve checks should I do first?

Where the link came from. It is the quickest to answer, and no later pass can repair it: a file from a source you cannot account for starts with a handicap. Then ask why you want the file at all. If someone told you a file is needed to log in or claim a bonus, stop there.

Why is Reviews the only check marked as the weakest?

Ratings and download counts on a page that offers a file are typed by whoever uploaded it, and reviews elsewhere can be bought or copied. So good reviews never outweigh a problem in another check. Bad reviews that describe lost money, locked accounts or surprise requests are worth taking seriously.

I already installed the file and now I see a problem. What should I do?

Stop using the app and remove it: touch and hold its icon and choose Uninstall, or open Settings, then Apps. If you typed card or UPI details, or paid someone, call your bank straight away and call 1930, the national cyber-fraud helpline. Report it at cybercrime.gov.in and keep the screenshot of the page.

What happens to my ticks when I copy a link to my result?

The link carries your twelve answers after the # sign, which a website never receives. Whoever opens it sees the same ticks and the same result on their own phone. Nothing is stored on this site, and there is no account. Send it only to someone you want to show.
