Privacy Policy for Sum Trail

Last updated: June 1, 2026

Your privacy is important to us. This policy explains how Sum Trail handles data when you use the app.

About the App

Sum Trail is an offline-first math path puzzle game. The app can be used without creating an account or signing in.

Data Stored on Your Device

Sum Trail stores some game data locally on your device, including:

• Your gem balance and level progress
• The current level and any unfinished trail, so you can resume
• Daily challenge completion history and streaks
• Your selected theme and any themes you have unlocked
• Whether you have seen the tutorial and first-time tile tips

This data is stored using app storage on your device. We do not use this data to identify you personally.

You can clear this data at any time by uninstalling the app or clearing its storage in your device settings.

Personal Data

Sum Trail does not require account sign-in.

We do not ask you to provide:

• Name
• Email address
• Phone number
• Account login details

However, third-party advertising providers such as Google AdMob may process limited technical data as explained in the Advertising section.

Advertising

Sum Trail may use Google AdMob to show ads, such as rewarded ads that grant optional in-game gems.

The app is currently configured for child-appropriate ad treatment, including:

• Max ad content rating set to G (general audiences)
• Child-directed treatment tag set to YES
• Under age of consent tag set to YES

AdMob and its partners may process limited technical data such as:

• Device information
• Advertising ID or similar device/ad identifiers, where available and permitted
• Approximate location
• Ad interaction data
• App activity related to ad delivery, measurement, and fraud prevention

This data may be used to show ads, measure ad performance, prevent fraud, and support advertising compliance.

Because the app is currently configured for child-appropriate ad treatment, we do not request personalised ads, interest-based advertising, or remarketing ads.

Consent for Ads

For users in the United Kingdom, European Economic Area, and Switzerland, Sum Trail may show a consent or privacy message before loading ads where required.

The app is currently configured to request child-appropriate, non-personalised ad treatment.

Data Sharing

We do not sell your personal data.

Limited technical data may be processed by third-party advertising providers for:

• Ad delivery
• Ad measurement
• Fraud prevention
• App advertising compliance

Analytics and Crash Reporting

Sum Trail does not currently use analytics or crash reporting tools.

If this changes in the future, this privacy policy will be updated.

Device Permissions

Sum Trail does not request access to sensitive device features such as:

• Contacts or address book
• Camera or microphone
• Phone or SMS capabilities
• Precise device location

Children

Sum Trail is designed for a general audience, including children.

For ad requests, we currently apply child-directed and under-age-of-consent settings as described above.

We will only change these settings if the app’s target audience, product design, legal requirements, or store policy requirements change.

Changes to This Policy

We may update this privacy policy in future app versions. Updates will be reflected by changing the “Last updated” date.
