Privacy policy

Last updated: 2019/02/12

This privacy policy outlines how Productivity Challenge Timer uses information collected from users. We reserve the right to modify this policy, so please review it frequently. Your continued use of the app signifies your acceptance of any changes to this privacy policy.


Productivity Challenge Timer doesn't allow users to create accounts and doesn't use any of your existing accounts, so it has no access to any of your account information. The only personally identifiable information we store is your email address if/when you contact support. However, the app does collect and share some of your device's identifiers and personal data with third parties in order to obtain analytics, personalize ads and report crashes.


Productivity Challenge Timer allows third party analytics service Answers by Fabric to collect usage data that is essential for us to provide services and understand the users' needs. This data includes but is not limited to unique device identifiers, installation UUID's, device hardware and firmware information and custom app events. None of this data can be used by us to personally identify the end users of our app.
Answers by Fabric retains the data for 90 days. You can review Fabric's privacy policy at


Productivity Challenge Timer is by default an ad-supported app that displays advertisements tailored to your interests. These advertisements are provided by the third party service AdMob. To facilitate this, the app shares your Advertising Identifier with AdMob.

You can disable ad personalization or reset your Advertising Identifier in your iOS device's Settings > Privacy > Advertising.

Crash reports

In order to improve the stability and reliability of the app, Productivity Challenge Timer reports any app crashes via the third party crash reporting service Crashlytics by Fabric. The reported data consists of crash traces, device make and model and the installation UUID.
Crashlytics retains the data for 90 days. You can review Fabric's privacy policy at
