Privacy Policy

Last updated: 8 July 2026

Stu is built with your privacy in mind. Your home data stays on your device. This page describes what information Stu collects and how it is used.

Your home data stays on device

All data you enter into the app, including your home profile, maintenance tasks, and completion history, is stored locally on your iPhone and never leaves your device. Stu does not collect, store, or transmit your home information.

No account required

Stu does not require you to create an account or provide an email address. There is no login, no cloud sync, and no server that stores your data.

App analytics

Stu uses PostHog to collect basic, anonymized usage information to help improve the product. This includes general details such as your home's state, climate zone, construction type, and in-app navigation patterns. No personal identifiers, home profile content, or task details are included in these reports.

Local storage only

All app data is stored using local device storage on your iPhone. Stu does not use iCloud, network services, or any remote database. Your data is retained until you delete the app.

Data export

You can export your home data directly from the app at any time. Your data is stored in a standard format and is never locked in. If you delete the app, your data is removed from your device.
