Privacy Policy
This Privacy Policy explains how Just Sum! (the “App”) handles information when you use it. It is intended to give you a clear view of local game data and third-party advertising services.
1. Information We Collect Directly
The App does not require an account. We do not directly collect your name, email address, phone number, precise location, or similar personal information through the App.
Level progress, clears, play time, best times, no-mistake clears, hint count, achievements, and settings are stored on your device. They are not sent to a developer server.
The App does not use Game Center. There is no account-based leaderboard or cloud synchronization.
2. Information Processed by Third-Party SDKs
The App uses Google AdMob and Google User Messaging Platform (UMP). Ads may include App Open, adaptive banner, interstitial, and rewarded formats.
For ad delivery, measurement, fraud prevention, and—when permitted—personalization, these services may process advertising, app, and device identifiers (including IDFA when allowed), IP address and approximate region, device and operating-system details, app version, ad impressions and interactions, and diagnostic information. Google’s handling is governed by its policies:
3. Consent and Privacy Options
Depending on your region, Google UMP may show a consent message before ads are initialized. If available, you can show the Privacy Options form again from the privacy settings inside the App.
4. App Tracking Transparency
When required, Apple’s App Tracking Transparency (ATT) prompt asks whether the App may access the Identifier for Advertisers (IDFA). If you do not allow it, the IDFA cannot be used by the App, although ads may still be shown.
You can change this choice in iOS Settings → Privacy & Security → Tracking. The exact ad experience can also depend on consent and other signals handled by the advertising provider.
5. SKAdNetwork
The App uses Apple’s SKAdNetwork, a privacy-preserving framework for measuring advertising attribution without identifying individual users.
6. Children’s Privacy
The App is for a general audience and is not directed to children under 13, or the equivalent minimum age in your region. We do not knowingly collect children’s personal information directly through the App.
7. Data Retention
We do not directly collect personal information on developer servers. Game data remains on your device until you delete the App or its local data. Google retains information it processes according to Google’s policies.
8. Your Choices
- Use the in-app Privacy Options form when it is available.
- Manage the ATT choice in iOS Settings → Privacy & Security → Tracking.
- Delete the App to remove locally stored game data.
- Use Google’s advertising settings where applicable.
9. International Users
Advertising partners may process information in countries other than the country where you live, subject to their policies and applicable safeguards.
10. Changes to This Policy
We may update this policy when the App or its data practices change. We will update the Last updated date at the top of this page when we make a change.
