This Privacy Policy applies to the Tracewell: One Line Puzzle mobile game ("Tracewell," "the App," "the Game"), available on the Apple App Store. It explains what information is collected when you play, why, and the choices you have. By using the App, you agree to the practices described in this policy.
Tracewell is a calm, single-player puzzle game. Tracking for ads happens only if you allow it. You never create an account, and we never ask for your name, email address, phone number, contacts, photos, or precise location. Your game progress is saved on your device. The App is free to play and supported by ads; to understand how the game is used and to keep it stable, it also uses Google Firebase for anonymous analytics and crash reports. Everything is described below.
To let you pick up where you left off, the App saves the following locally on your device only:
This data is not sent to our servers and is not synced to any cloud service by us. It is deleted when you delete the App.
We use Google Firebase Analytics to understand how players experience the game, for example which levels are started, completed, or abandoned; where players get stuck; how often hints, skips, and settings are used; which screens are opened; and how the Remove Ads offer is used (shown, bought, restored, or closed — never your payment details). This helps us balance level difficulty and fix confusing parts of the game.
Along with these gameplay events, Firebase receives basic technical information: device model, iOS version, app version, language, an anonymous Firebase-generated app instance identifier, and approximate (country/region-level) location derived from your IP address.
If the App crashes or encounters a serious error, Firebase Crashlytics sends a crash report so we can find and fix the problem. A crash report contains technical details such as the part of the code that failed, the device model, iOS version, app version, and an anonymous installation identifier. It does not contain personal information.
Google's handling of Firebase data is described at https://firebase.google.com/support/privacy/.
Tracewell is free to play and shows ads provided by Google AdMob:
To deliver, measure, and limit ads and to prevent fraud, Google may collect information from your device, such as IP address and approximate location, device and operating system information, app information, and how you interact with ads (views and taps). Google may also use cookies or similar technologies and device identifiers, such as an identifier for vendors. If you allow tracking when the App asks (see Section 8), Google may also use your device's Advertising Identifier (IDFA) to show more relevant ads and to measure them across apps and websites owned by other companies. If you do not allow tracking, the IDFA is not available to the App or to Google. Depending on your region and your choices, ads may be personalized or non-personalized.
Google's use of this information is governed by Google's Privacy Policy (https://policies.google.com/privacy). You can learn how Google uses information from apps that use its services at https://policies.google.com/technologies/partner-sites.
Tracewell offers an optional one-time in-app purchase, "Remove Ads", that turns off banner and between-level ads. All purchases are processed by Apple through the App Store using Apple's StoreKit. We never receive your name, Apple ID, or payment card details. The App checks with Apple, on your device, whether you own Remove Ads, so it can turn ads off, keep them off after a reinstall, and let you restore the purchase on your other devices. Apple's handling of payment information is governed by Apple's Privacy Policy.
When you download Tracewell through the Apple App Store, Apple may collect information as part of its platform operations, governed by Apple's Privacy Policy, not ours. If you have opted into sharing App Analytics with developers in iOS Settings, Apple may share aggregated, anonymized usage and crash statistics with us. You can change this at any time in Settings → Privacy & Security → Analytics & Improvements.
We do not sell your personal information for money, and we do not use data brokers.
If you contact us at feedback.sfsk@gmail.com for support or feedback, any information you provide is:
On your device: game progress and settings remain on your device until you delete the App, which removes them.
Firebase: analytics data is kept by Google for a limited period (we use a retention period of no more than 14 months) and crash reports for up to 90 days, after which they are deleted automatically.
Advertising: data collected by Google for advertising is retained according to Google's policies.
Requests: because analytics and crash data are anonymous and not linked to your identity, we may not be able to locate a specific person's records. If you would like us to try, email us with the details in Section 17 and we will help where we can.
Depending on where you live, including under the GDPR (EU/UK), the California Consumer Privacy Act (CCPA/CPRA), and other laws, you may have the right to access, correct, delete, or restrict the use of your personal data, to object to its processing, to withdraw consent, and to opt out of targeted advertising. You can withdraw or change ad consent at any time in Settings → Privacy choices. For anything else, contact us using the details below. We will not discriminate against you for exercising any of these rights.
Where the GDPR applies, our legal bases are your consent (for personalized advertising and related storage on your device) and our legitimate interests (to keep the game working, measure its performance, fix crashes, and show non-personalized ads).
Tracewell is a puzzle game suitable for a general audience, but it is not directed at children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has provided personal information through the App, please contact us and we will take appropriate steps to delete it.
We may update this Privacy Policy from time to time, for example when we add features or change service providers. When we do, we will revise the "Last Updated" date at the top of this page. If a change materially reduces your privacy protections, we will notify you in the App before it takes effect. Continued use of the App after an update means you accept the revised policy.
