Privacy Policy for Sum Trail

Last updated: July 27, 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 uses Google AdMob to show ads. These include rewarded ads that grant optional in-game gems, and occasional full-screen (interstitial) ads shown between levels. A one-time in-app purchase to remove the interstitial ads is available.

For ad requests, the app currently sets:

• Maximum ad content rating: PG (parental guidance)
• A consent or privacy message where Google requires one; your choices there determine whether personalised ads are used

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.

Whether personalised or non-personalised ads are shown depends on your region and the consent choices you make.

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.

Your choices in that message determine whether personalised or non-personalised ads are shown.

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

Limited technical and usage data is also processed by Google for analytics, as described below.

Analytics

Sum Trail uses Google Analytics for Firebase to understand how the app is used in aggregate — for example app opens, sessions, and general usage trends — so we can improve it.

Firebase Analytics is provided by Google and may process limited technical and usage data, such as:

• Device and app information (e.g. device model, operating system, app version)
• A Firebase installation identifier and, where available and permitted, an advertising identifier
• In-app events and usage activity
• Coarse location estimated from IP address

We use this data to analyse performance and usage in aggregate and do not use it to identify you personally. Sum Trail does not currently use a separate crash-reporting tool.

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 intended for a general audience and is not specifically directed to children.

Ad requests use a maximum content rating of PG, as described in the Advertising section above. Parents or guardians should supervise children’s use of the app where appropriate.

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.
