PipeFitter Calc — Last updated: August 14, 2026

1. Overview

PipeFitter Calc ("the App") is a free Android app developed by 강건한건강 ("we", "us") that calculates pipe offsets, fitting takeouts and finished cut lengths for pipefitters. This Privacy Policy explains how we handle information when you use the App.

2. Information We Collect

The App does not collect, store, or transmit any personal information to our servers. There are no user accounts, no sign-up, and no cloud sync. Your saved fitting takeouts and entered measurements are stored only on your device in a local database.

3. Third-Party Services

The App uses the following third-party service:

• Google AdMob — for displaying advertisements. The App shows a bottom banner, an app-open ad on launch (limited to once per day), and an interstitial ad when you switch between calculators. AdMob may collect device identifiers (such as the Advertising ID) and usage data to serve personalized or non-personalized ads. Your measurements are never shared with AdMob or any other third party. For more information, see the Google Privacy Policy.

4. Permissions

• Internet — used only to load advertisements. The calculations run entirely on your device and works with no connection at all.

The App does not use or request access to your location, camera, microphone, contacts, or photos.

5. Data Storage and Sharing

The App does not create user accounts and does not sync any data to the cloud. When you share a cut sheet, the image is handed to the app you choose (for example a messaging or email app) by your own action — we never receive a copy. Uninstalling the App removes your local data and any cached AdMob data stored on the device.

6. Children's Privacy

The App is suitable for general audiences and is not directed at children under the age of 13. We do not knowingly collect personal information from children.

7. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
