Privacy Policy
Last updated: 1 September 2026 · Applies to XPipe Pro for iOS and Android
XPipe Pro collects nothing about you. It has no network code, no analytics, no advertising and no accounts. Everything you type stays on your phone.
Who is responsible
XPipe Pro is made and published by Jakub Trytek. For anything in this document, write to kubatrytek@gmail.com.
What the app collects
Nothing. No personal data, no usage data, no device identifiers, no diagnostics, no location. The app does not send anything anywhere, because it contains no code that talks to a network.
What is stored on your device
So the app can pick up where you left it, the following is kept in the app's own private storage on your phone:
- Your settings: language, millimetres or inches, decimal places, theme, root gap and haptics.
- The pipe and elbow you last chose, so the calculators open on it.
- Measurements you save yourself, and the scientific calculator's own log.
None of it leaves the device. No part of it is readable by other apps. Deleting the app removes all of it; you can also clear the saved measurements from inside the app at any time.
Permissions
The app asks for no permissions at all. It does not request internet, storage, camera, contacts, location or anything else.
Third parties
There are none. No advertising networks, no analytics or crash-reporting services, no social sign-in, no software development kits belonging to anyone else. Nothing about you is shared or sold, because nothing about you is gathered.
Apple and Google may collect their own information when you download or update the app from their stores. That is covered by their policies, not by this one.
The tester form on the website
The one thing on the website that asks for anything is the closed-test form on the front page. It sends the address you type, and the optional note beside it, to kubatrytek@gmail.com — either straight from your own mail program, or through a form relay if one is configured. There is no database behind it and no newsletter attached to it.
The address is used to put you on the Google Play tester list and to send you the opt-in link back. It is deleted when the closed test ends, or sooner if you ask.
Children
The app is a work tool rather than something aimed at children, but it is safe for any age: it gathers no data from anyone.
Your rights
Rights of access, correction, erasure and portability under the GDPR apply to data held about you. The app holds none — what it stores is on your own phone and under your own control. If you sent your address through the tester form, write to kubatrytek@gmail.com and it will be removed from the list.
Changes
If a future version of the app ever does anything with data, this page will say so before that version ships, and the date at the top will change.
A word about the figures
XPipe Pro is a calculating aid, not a substitute for your own judgement or for the drawings and standards a job is built to. Check a figure on the steel before you cut.
