Privacy Policy

The History – Reparations is primarily an offline educational reference. Historical timelines, citations, calculator models, and state-by-state data are bundled with the app and do not require a network connection to read.

The app may store your display preferences locally on your device, such as currency display settings and cached exchange-rate values used only for USD/EUR formatting.

If you create an account, the app collects the information needed to sign you in:

• your email address,
• a password processed and hashed by Firebase Authentication,
• a unique user ID generated by Firebase,
• and the date your account was created.

If Firebase is not configured in a given build, the app may use a local development sign-in mode on that device only. Production App Store builds use Firebase Authentication when credentials are present at build time.

We use account information solely to authenticate your session and maintain access to the app. We do not sell personal information. We do not use your account for advertising or political campaigns.

Historical and calculator content is processed locally on your device. We do not operate analytics or usage-tracking services in the app.

Firebase Authentication and Cloud Firestore (Google LLC) process account sign-in and may store basic profile metadata needed for authentication. Google's privacy practices are described at firebase.google.com/support/privacy.

When you choose EUR display, the app may request a public exchange-rate feed from frankfurter.app to convert USD figures for display only. If that request fails, the app uses a cached or fallback rate stored locally on your device.

External source links in the historical record open in your device's browser. Those sites operate under their own policies.

Account data retained by Firebase remains until you request deletion. You may request deletion of your account and associated authentication data by contacting privacy@ovairasystems.com. We aim to process verified deletion requests within 30 days.

Local preferences stored on your device can be cleared by removing the app from your device.

The app contains mature historical content and is rated 17+. We do not knowingly collect information from anyone under 17. If you believe a minor has created an account, contact privacy@ovairasystems.com and we will delete the account.

When we update this policy, we will revise the date shown at the top of this page and in the in-app Privacy Policy screen. Continued use of the app after an update constitutes acceptance of the revised policy.
