Privacy Policy

Last updated: November 2, 2026

Event Horizon ("the app", "we") is an idle astronomy game made by an independent developer. This page explains what happens to your information when you play it, in plain language.

1. Information we do not collect

There is no sign-up and no login. Event Horizon never asks for your name, email address, phone number, contacts, precise location, or access to your camera or microphone. We don't run a server that receives your gameplay.

2. What's stored, and where

Your progress (energy, levels, missions, discoveries, purchases you've unlocked) and your settings (sound, ambience, vibration, notifications) are saved only on your device, in the app's own storage. The pictures in your observation journal are also saved only in the app's storage. We never receive a copy. Resetting progress in Settings, or uninstalling the app, removes them.

3. Sharing

When you choose to share a journal picture, the app opens Apple's share sheet with that picture. Where it goes is up to you; the app sends nothing on its own.

4. Notifications

If you allow notifications, the app schedules reminders on your device (for example, when the night's observing plan is ready). They are created and shown by iOS locally; nothing is sent to us. You can turn them off in the app's Settings or in iOS Settings.

5. In-app purchases

Optional purchases (time skips, permanent double output and No Ads) are sold through Apple's App Store and processed with RevenueCat, which receives an anonymous app user ID and the purchase record so the app can unlock what you bought and restore it. Payments are handled entirely by Apple; we never see or store your payment details.

6. Advertising (Google AdMob)

The app shows ads, including optional rewarded video ads (for example, watching an ad to double a reward), through Google AdMob. To serve, cap and measure ads and to prevent fraud, Google may collect:

• a device advertising identifier (on iOS, only if you allow tracking; see below),
• your IP address and the approximate location derived from it,
• device and app information (model, OS version, language, app version),
• ad interactions (which ads were shown or tapped), and
• diagnostic data such as crash and performance information from the ad SDK.

You can learn how Google uses this information at How Google uses information from sites or apps that use our services.

Tracking choice on iOS: on iOS 14.5 and later the app asks for permission through Apple's App Tracking Transparency prompt before the advertising identifier is used. If you decline, you still see ads, but they are not personalized using that identifier. You can change this any time in iOS Settings → Privacy & Security → Tracking.

The No Ads purchase removes the ads.

7. Analytics

Event Horizon does not include analytics or crash-reporting software. If that ever changes, this policy will be updated first.

8. Children's privacy

Event Horizon is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

9. Changes to this policy

If this policy changes, the "Last updated" date above will change too, and any change that affects what data is collected will be described plainly.
