Isofitters Privacy Policy

Last updated: October 23, 2026

Isofitters is a sketching and take-off app for the pipe trades. It is made by Timothy Patton.

What we collect

Nothing. The app has no accounts, no ads, no analytics and no tracking. It does not use the internet to send anything to us or anyone else.

Your drawings

Your drawings and settings are saved only on your phone. They leave your phone only when you choose to share or export them (for example a drawing file, picture or PDF sent through your phone's share menu). Where they go after that is up to you and the app you share them with.

Android may include the app's data in your phone's own backup to your Google account, if you have backups turned on. That backup is handled by Google under your account settings, not by us.

This website

This website has no cookies, no analytics and no tracking. The company that hosts it may keep standard server logs (such as IP addresses) for security, as all web hosts do.

Children

The app is made for working tradespeople and is not aimed at children.

Changes

If this policy changes, the new version will be posted on this page with a new date.
