Privacy Policy
1. Your data stays on your phone
Timersmith is a timer. Your rest and interval timers, saved presets, the daily set tally and your last sessions are stored only in the app's private storage on your phone. We do not collect workout data, health data, your location, your contacts, photos, microphone or camera, and we operate no servers that process your content; cloud backup of that storage is disabled. There is no account and no sign-in. Timer times are measured with the phone's own clock; no sensor data is read. A backup or a shared preset only leaves the phone if you choose to save or share it (you pick the file or app yourself).
2. Permissions
- Notifications (POST_NOTIFICATIONS) — asked when you start your first timer. Used for the ongoing countdown on your lock screen and notification shade (with Pause, +15 s and Skip buttons) and, only if you turn it on, a workout reminder. If you decline, timers still run while the app is open and Timersmith shows a row where you can allow it later.
- Foreground service (FOREGROUND_SERVICE, FOREGROUND_SERVICE_HEALTH) — keeps your running timer and its beeps on time while the screen is off or you use another app, such as your music player. It runs only while a timer is running and stops when it ends. The related HIGH_SAMPLING_RATE_SENSORS permission is a standard (non-dangerous) permission Android requires alongside this service type; Timersmith does not read any sensor.
- Wake lock (WAKE_LOCK) — keeps the phone's processor awake only while a timer is running so the beep and vibration happen on time.
- Vibration (VIBRATE) — vibrates at the end of a timer segment if you leave vibration on.
- Files — no storage permission. Backups use Android's file picker, so you choose where a file is saved or which file is restored.
- Internet — ads, analytics, purchases and consent. Your content is never sent.
3. Analytics and crash reports (Google Firebase)
With your consent where required, we use Google Analytics for Firebase and Firebase Crashlytics to understand how the app is used and to fix crashes. We log anonymous events such as “paywall viewed” or “purchase completed”, plus device model, OS and app version, approximate region and an app-instance identifier. We never log your content; the app enforces this with an allow-list of event parameters. Crash reports contain the error type and stack trace only. Firebase Remote Config is used to tune paywall and ad settings.
4. Advertising (Google AdMob and Unity Ads)
The free version shows ads: one slim banner on the History screen, a full-screen ad now and then after you finish an interval session, and optional rewarded ads you choose to watch to unlock a Pro tool for a while. Ads never appear while a timer is running, during onboarding or on the paywall, and never appear in the first two minutes of first use. Timersmith Pro removes all ads.
Ads are served by Google AdMob, with Unity Ads competing through AdMob mediation and serving the banner directly. These partners may collect the advertising ID, device and usage information and approximate location derived from your IP address to serve and measure ads. See Google's and Unity's privacy policies.
5. Your choices (GDPR, UK GDPR, Swiss FADP, US state laws)
In the EEA, the UK and Switzerland, Timersmith asks for your consent through Google's consent message (IAB TCF) before personalised ads or analytics are used. If you decline, ads are non-personalised and analytics stays off. In US states with privacy laws (such as California, Virginia, Colorado), you can opt out of the “sale” or “sharing” of personal information and targeted advertising. You can change your choice at any time in Settings → Privacy choices.
Legal bases (GDPR): consent for analytics and personalised ads; performance of a contract for the features you use and for purchases; legitimate interest for crash diagnostics where consent is not required. You may request access, deletion, correction or portability of data we control, object to processing, or lodge a complaint with your supervisory authority. California residents (CCPA/CPRA): we do not sell personal information for money; ad partners may receive identifiers as described above, which you can opt out of in Privacy choices. We do not discriminate against users who exercise their rights.
6. Purchases
Subscriptions and the lifetime purchase are processed by Google Play. We never receive your payment details; Google tells the app whether Pro is active.
7. Retention and deletion
Your content remains on your device until you delete it or uninstall the app. Analytics data is retained by Google for up to 14 months. See how to delete your data.
8. Children
Timersmith is not directed to children under 13 (under 16 in the EEA) and we do not knowingly collect their data.
9. Changes
We will update this page if our practices change and revise the date above.
