Pipefitter Offset Calculator — Privacy policy
Effective date: September 15, 2026
Pipefitter Offset Calculator works out pipe offsets — travel, run and the finished cut length after fitting take-offs and weld gaps — on Android and iPhone, and is made by Pro Vision Services LLC (Fairbury, Illinois). It is designed to collect as little as possible. There is no account, no login, and no email address is ever asked for.
What stays on your device
- Your last cut. The set, run and roll you typed are saved on the phone so a half-entered calculation survives the app being closed. This never leaves your device.
- Your setup. Fitting angle, pipe size, elbow type, joint type, the gap for each joint type, and the fraction precision you work to are stored on the device only.
- Your preferences. Whether the screen should stay awake while an answer is showing.
- How many free cuts you have used. A count, stored on the device, so the app knows when the ten free cuts are spent. Reinstalling the app resets that count, which is deliberate.
- Whether you have unlocked the cut length. Stored on the device so the feature keeps working with no signal.
What leaves your device
- An anonymous purchase identifier. To sell and restore the one-time unlock, the app uses RevenueCat, which assigns a random anonymous identifier to the installation. It is not your name, email, phone number, Google account or Apple Account, and it is not linked to any of them. It exists so that a purchase can be restored if you reinstall or change phones.
- Purchase records. Google Play (on Android) or the App Store (on iPhone) processes the payment and tells RevenueCat whether it succeeded, so the app knows to unlock the feature. We never see your card or payment details.
That is everything the app collects, and it is used only to sell, check and restore the unlock.
Sending a cut to someone
When you share a cut it is sent as plain text, built on your phone from the numbers you typed, so that it survives being pasted into a text message. Your phone's own share sheet sends it wherever you choose — a message, an email, a notes app. That destination is your choice, and the text never passes through our servers.
What the app does not do
- No ads, and no advertising identifier. The app does not request the Android advertising ID or Apple's advertising identifier, and it never asks to track you.
- No analytics, no tracking, no crash reporting.
- No account, no sign-in, no email address collected.
- No location, camera, microphone, contacts or files on your phone. The app requests no permissions of any kind, on Android or iPhone. Keeping the screen awake is a display setting, not a permission.
- Nothing is sold or shared with advertisers or data brokers.
Who else handles your data
RevenueCat stores the anonymous purchase identifier and purchase records on our behalf and uses them only to process and restore purchases. Any service provider that receives this data must give it the same or equal protection as this policy. Payments themselves are handled by Google Play or Apple under their own privacy policies.
Children
This is a tool for pipefitters and steamfitters laying out pipe. It is not directed at children and collects nothing that could identify one.
Keeping and deleting your data
Everything the app stores about your work lives on your phone; uninstalling the app deletes it. The anonymous purchase record is kept for as long as it is needed to restore your unlock. To have it deleted, email support@provision.services and say which app you mean. Note that deleting the purchase record also removes our ability to restore your unlock.
You can withdraw consent at any time: uninstall the app and nothing more is sent, then email us to have the purchase record deleted.
