CoreForge is an HVAC certification exam study aid. It runs entirely on your device. There is no account to create, no login, and nothing you study is sent to us. This page explains the one place data does leave the app — the advertising component — and exactly what you can do about it.
This app is published by TapForge Studios (99 Cent Apps LLC), Crown Point, Indiana, USA. For any privacy question, contact contact@tapforgeapps.com.
The following is written to local storage on your phone and is never sent to us or to anyone else:
This lives in a local database and a local settings file inside the app's private storage. If Android backup is enabled on your device, this data may be included in your own Google backup, which is governed by Google's Privacy Policy, not by us. Uninstalling the app deletes all of it. You can also clear it at any time from About → Reset all progress.
The app itself collects nothing. Its advertising component does. This table matches the Data safety declaration on our Google Play listing.
| Data type | Collected | Shared | Purpose | Optional? |
|---|---|---|---|---|
| Device or other IDs (advertising ID) | Yes | Yes | Advertising, fraud prevention | Removed by purchasing Pro |
| Approximate location (derived from IP address) | Yes | Yes | Advertising, legal compliance | Removed by purchasing Pro |
| App interactions | Yes | Yes | Advertising, analytics | Removed by purchasing Pro |
| Crash logs and diagnostics | Yes | Yes | Stability and performance | Removed by purchasing Pro |
All of it is transmitted over an encrypted connection. We do not sell personal information, and we do not run any analytics SDK of our own — the only third party in the app is Google.
Serves the banner, interstitial and rewarded ads in the free version. AdMob's handling of data is described in How Google uses information from sites or apps that use our services and in Google's Privacy Policy. You can limit ad personalisation at the OS level via Settings → Google → Ads, and reset or delete your advertising ID there.
In the European Economic Area, the United Kingdom and Switzerland, the app shows a consent form on first launch before any personalised advertising occurs. Your choice is stored by Google's consent framework. Where that form applies, you can change your answer later from the privacy options the app presents.
Handles the optional one-time purchase. The transaction happens inside Google Play — we never see or store your card number, billing address or any payment credential. The app receives only a token confirming the purchase.
Buying CoreForge Pro disables all advertising in the app. Once purchased, no ad requests are made and the AdMob data collection above stops.
INTERNET and ACCESS_NETWORK_STATE — required to
fetch ads and to complete a purchase. All study content ships inside the
app and needs no connection.com.google.android.gms.permission.AD_ID — access to the
advertising ID, required by AdMob.The app requests no access to your camera, microphone, contacts, files, precise location, or any other sensitive permission.
CoreForge is a professional trade-certification study aid intended for adults working in or entering the HVAC trade. It is not directed to children, and we do not knowingly collect personal information from anyone under 13. If you believe a child has provided information through this app, contact us and we will act on it.
Because we hold no personal data about you on any server, there is no account for us to look up, export or erase. In practice:
If you are in the EEA, the UK, California or another region with statutory data rights, you may still contact us at contact@tapforgeapps.com and we will respond within 30 days.
