App: Temporis: Learn History

Last updated: 6 September 2026

1. Overview

Temporis is an offline-capable history learning app. We process as little personal data as possible. There are no user accounts, advertising, or ad tracking. An optional usage-statistics feature, disabled by default, can be turned on in the app settings.

• Learning progress and settings are stored only locally on your device.
• The app does not ask for names, email addresses, contacts, location, or camera data.
• Optional Temporis Pro subscriptions involve technical purchase and subscription data processed through Google Play and RevenueCat.
• Usage statistics are sent only if you explicitly enable them in the app.

3. Local app data

Temporis stores learning progress, activity results, settings, language, and the locally cached status of a previously confirmed subscription on your device. This data is not transmitted to us. You can delete local app data through Android settings.

4. Subscriptions through Google Play and RevenueCat

Temporis Pro is an optional monthly or yearly subscription. Payment is handled by Google Play. The app uses RevenueCat, Inc. to display and verify subscription status. This may include a random app user ID, product and purchase data, transaction data, and subscription status and expiry information. We do not receive full payment details such as credit card numbers.

This processing is used only to provide, restore, and manage the subscription. See RevenueCat's privacy policy at https://www.revenuecat.com/privacy/.

5. Optional usage statistics (PostHog)

With your explicit consent, the app sends pseudonymous usage data to PostHog (PostHog Inc., EU cloud data centre in Frankfurt am Main, Germany). This feature is off by default and only becomes active after you enable it in the app. You can withdraw your consent at any time in the app settings; locally queued, unsent data is deleted when you do.

Data collected: a pseudonymous random app-local ID (no account name, email, or advertising ID), app version, language setting, subscription status (free/Pro), events such as campaigns opened, lessons started and completed with a coarse quiz result band, screens viewed, app starts, and technical error reports. No content you type, no location data, no advertising.

Purpose: improving learning content and usability (error analysis, popular content, aggregate insight into learning progress). The legal basis is your consent (Art. 6 (1)(a) GDPR). A data processing agreement is in place with PostHog. More information: https://posthog.com/privacy

6. Permissions and network access

Learning content and progress work offline. An internet connection is needed only to purchase or restore a subscription or update its status, and, with your consent, to send usage statistics. The app does not access the camera, microphone, contacts, or location.
