As a research data collection app, Timer will collect three types of data:
Responses to the in-app surveys
Locking and unlocking of the screen
Changes made in the app settings
Timer will not collect any personally identifiable information.
There are four in-app surveys. The questions are about smartphone usage and experience with Timer. Except two open-ended questions, all other questions are to be rated on a 5 point scale.
Timer records the timestamps of users’ locking and unlocking of the phone screen. For example:
Unlock: 2024-01-01 20:55:10.000,
Lock: 2024-01-01 20:59:10.524.
Timer also records the changes of Timer settings. For example:
Variable: animationEnabled,
New value: false,
time: 2024-02-01 13:49:56.281.
After you login, Timer will check and upload the time zone information (in the format of "America/New_York") and the device information (Android version, Brand, and Model).
In Week 3, Timer will record changes of the phone's ringer mode: normal, vibration, or silent, in the format of {timestamp: 2024-01-01 20:59:10.524, newValue, 0}).
Data will be stored in Firebase realtime database (https://firebase.google.com/).
