Privacy Policy
Last updated: September 2026
Grease Sheet is a paid, offline-first reference application built for tradespeople. We designed it to respect your privacy. This policy explains, in plain terms, what we do and do not collect.
No account required
You do not need to create an account or sign in to use Grease Sheet. There is no login, no username, and no password stored by the app.
Works offline
All reference charts, conversions, and how-to guides are bundled with the app and read directly on your device. The core app does not require an internet connection and does not send your data to our servers.
Data we do not collect
We do not collect personal information, location data, usage analytics, or device identifiers from your use of the app. We do not sell or share any data with third parties.
What you create stays on your device
Any pages you print or export as PDF are generated locally on your device. That content is not transmitted to us.
App stores
Downloading or purchasing the app through Apple's App Store or Google Play is subject to those platforms' own terms and privacy practices. We do not control how Apple or Google handle transaction or account data.
Children
Grease Sheet is a professional reference tool and is not directed at children.
Changes to this policy
If we ever change how the app handles data, we will update this page. Any material changes will take effect with a new app release.
