Privacy Policy

Last updated: October 30, 2026

The short version

Your answers, scores and study progress are stored on your device only. There are no accounts, no third-party analytics and no advertising. The only data that leaves your device is what it takes to check a purchase of Propwash Pro, described below.

What leaves your device

• Purchases. If you buy Propwash Pro, Apple processes the payment. We use RevenueCat to check the purchase and unlock Pro. RevenueCat receives your purchase history for this app and an anonymous app user identifier, a random value created for this app. It never receives your name, your email or your Apple Account. See RevenueCat's privacy policy.
• Feature settings. The app may fetch a small anonymous configuration file from our server so a broken feature can be switched off without an update. The request carries no identifier and nothing about you or your progress.
• Crash diagnostics. Standard Apple crash reports, only if you opted in to sharing analytics with app developers in iOS Settings.

What we collect through the app

The App Store privacy label reads Data Not Linked to You: Identifiers, Purchases. In those terms: Identifiers (the anonymous app user identifier) and Purchases (purchase history), used only for App Functionality, to check and restore your purchase. Neither is linked to your identity and neither is used for tracking. Nothing else is collected: your study progress never leaves your device.

Your data, your device

Deleting the app deletes your study progress with it. A purchase stays with your Apple Account and comes back with Restore Purchases.

Children

Propwash is not directed at children under 13 and collects no personal information.

Changes

If this policy changes, the new version is posted at this address with an updated date.
