Privacy Policy

AI Don't Fix Stupidity · Last updated 2026-08-07

This Privacy Policy describes how the iOS app AI Don't Fix Stupidity (the “App”), developed by Magnus Oxenwaldt (“we”, “us”, “our”), collects, uses and shares information.

What we collect

Account information (optional)

On first launch the App signs you in anonymously via Supabase. No email, no password and no personal details are required to use it.

During onboarding the App optionally asks for:

• Email address — if you provide it, we use it to identify your account across devices and to contact you about the App.
• Name, company, role, country — if you provide these, they help us understand who the App is reaching.

Every one of those fields is skippable, and the App works fully without them.

App usage

• Progress — which chapters you have opened and finished, your XP, your streak, your assessment score.
• Plan checkmarks — which items you have marked complete on the ninety-day plan.
• Runtime preferences — which Advisor tier you have chosen.

This lives on your device and syncs to your anonymous account row in Supabase, so your progress survives reinstalls when you have provided an email.

Diagnostics

We use Sentry for crash reporting. A crash report includes the stack trace, device model and OS version. Crash reports do not include your email or profile fields.

Product analytics

We use PostHog to understand which screens are visited and which features are used, so we can improve the App. PostHog events are linked to a randomly generated app-install identifier, not to your email address. You can opt out by deleting the App.

AI Advisor

The Advisor runs entirely on your iPhone via Apple Foundation Models, which requires iPhone 15 Pro or newer with Apple Intelligence enabled. Your Advisor conversations never leave your device. We do not collect, store or have any access to anything you type into the Advisor.

Data storage

Account and progress data are stored in Supabase (Postgres) in the EU (Frankfurt region). Crash reports are stored by Sentry. Product analytics are stored by PostHog in its US region.

What we do not do

• We do not sell your data to third parties.
• We do not show third-party advertising.
• We do not track you across other apps or websites.
• We do not use your content to train any AI model.

Your rights

• Access all data we hold about you by emailing magnus@oxenwaldt.com.
• Correct any profile field by contacting us.
• Delete your account and all associated data by emailing us — we will action it within 30 days. Deleting the App also removes everything held on the device.
• Export your progress and profile by emailing us; we will provide a JSON export within 30 days.

Children

The App is a professional tool and is not directed at children. We do not knowingly collect information from anyone under 13.

Changes to this policy

If we change this policy materially, we will update the “Last updated” date at the top and, where the App has a way to reach you, notify you in-app on next launch.
