Stack IT ("we", "the app") is published by Stackvaly. This policy explains what the
Stack IT E-Question Bank Android app (package com.stackvaly.stackit) does
with your information.
The app needs an internet connection to run — it is ad-supported, and it checks for a live connection every time you open it. Your questions, answers, progress and bookmarks are still stored only on your own phone. We do not ask you to create an account, and we do not collect your name, email address, phone number or location.
This data is stored in an encrypted database inside the app's private storage. It is never uploaded to us. Uninstalling the app deletes it.
The app shows advertisements through Google AdMob, including rewarded ads that unlock additional exam content and support the app's running costs. To serve and measure these ads, Google may collect:
We do not receive this data in a form that identifies you; we only see aggregate earnings reports. Google's use of this data is governed by the Google Privacy Policy and the Google Advertising policies. You can reset or delete your advertising ID at any time in Settings → Google → Ads on your device.
| Permission | Why |
|---|---|
INTERNET | Required to use the app at all — checking for a live connection, loading advertisements, and opening our website, Facebook and Telegram links |
ACCESS_NETWORK_STATE | Checking whether the device has a live connection |
AD_ID | Required by Google Play so AdMob can serve ads |
The app does not request access to your contacts, camera, microphone, files, location or phone state.
The app links to stackvaly.com, a Facebook group and a Telegram group. Once you follow a link you are on that service and its own privacy policy applies.
The app is made for adults preparing for public-sector, bank and private-sector job exams in Bangladesh. It is not directed to children under 13, and we do not knowingly collect information from them.
Stack IT E-Question Bank is an independent study app built by exam candidates for exam candidates. It is not affiliated with, endorsed by, or operated on behalf of the Government of Bangladesh or any government agency, and it does not provide any official government service. The exam papers it references are cited as historical recruitment-exam material for study purposes only. The full list below links every organisation named in the app to its own official website — always confirm current, official recruitment details there, not in this app. The same list is also inside the app under Settings → Official Sources.

A small number of exam-catalog entries name two organisations at once (combined recruitment notices) and are intentionally left off this list rather than guessing which one to link.
If this policy changes we will update the date at the top of this page and, where the change is significant, mention it in the app's update notes.
