Speed Stacking Timer Privacy Policy
Last updated: November 9, 2026
Summary
Speed Stacking Timer is a timer for sport stacking. Your training data stays on your phone. The app has no account and no server of ours. The only data that leaves your phone is described below: advertising (AdMob), and, only if you agree, usage statistics (Firebase Analytics) and crash reports (Firebase Crashlytics).
No account and no backend
You do not sign up for anything. We run no server that receives your attempts, times, notes or names.
Your training data stays on the device
Attempts, times, notes, stacker names, settings and Backups are stored only on your phone. They are excluded from Android's automatic backup and from device-to-device transfer, so they are not copied to your Google account. To move your data to a new phone, share a Backup file from Data and backups and import it there. "Clear all data" in the app deletes them from the phone.
Advertising: AdMob and UMP
The app shows ads with Google AdMob. The Google Mobile Ads SDK processes, for advertising, analytics and fraud prevention: your IP address (which can indicate a rough location), app interactions such as launches, taps and video views, diagnostic information such as launch time and hangs, and device identifiers such as the Android advertising ID and an app set ID. Whether ads are personalised depends on your consent where the law requires it. Google's use of this data is described in Google's privacy policy: https://policies.google.com/privacy
Where required (for example in the European Economic Area and the United Kingdom), Google's User Messaging Platform (UMP) asks for your consent when you first open the app. UMP stores your choice on the phone.
Usage statistics: Firebase Analytics
Only with your consent, Firebase Analytics receives usage events and technical data: a random app-instance identifier, device and app data (such as model, operating system and app version) and the app's own events: when a stacker is added or removed (with the number of stackers) and when adding a stacker meets the ad step (with its outcome). Events never contain names, results or times. Without consent nothing is sent.
Crash reports: Firebase Crashlytics
Only with your consent, Firebase Crashlytics receives crash reports: the stack trace, the state of the app at the time of the crash, device metadata (such as model and operating system), an installation identifier and, with Analytics on, a short trail of app events before the crash. Without consent no report is sent. A report made before you answered stays on the phone and is sent only if you consent, and deleted if you refuse.
Your choices
You can change your consent at any time in the app: CONFIG, Privacy, "Privacy settings" (shown where consent is required). Refusing does not limit what the app does, except for the ad rules shown in the app. You can also reset your advertising ID in Android's settings.
Age
The app is intended for people aged 13 and over. It is not directed at children under 13, and we do not knowingly collect their data. Younger children should use it only with a parent.
