Privacy Policy for Apps & Services

This Privacy Policy is adopted to explain what information is collected from apps made or services provided by me, and how this information is used.

Thereafter in this Privacy Policy, “App”/”Application” refer to applications I made, “You”/”Your”/”User” refers to the user of the app, and “I”/”me”/”we”/”us” refer to me

These apps automatically collect or use certain information as shown below.


Collected Data

For most apps, these might be collected, either automatically or through user-submissions, for the purpose of improving the app. The list below is exhaustive.

  • Your device type
  • Your device’s operating system
  • Your device’s operating system’s version
  • App usage analytics
  • App crash reports
  • Anonymous information about how you use the app (which section of the app you entered, what elements of the app have you interacted with etc.)

For automatic collection of data, this will occur by using data collected via Apple’s and/or Google’s Analytics. Any collected data cannot be traced to any singular device, except in the situation where a log for diagnostics purposes is attached in a user feedback. We do not collect Advertising Identifiers (such as iOS’s IDFA) in any form nor share that information with third-parties.

All apps hosted on the Apple App Store and Google Play Store will have data collected via Apple and Google, if you indicated to allow sharing App Analytics with Apple/Google and App Developers in your system settings. Otherwise, no information is collected via this channel.

For apps on the store, unless otherwise stated in App Store and Play Store app privacy notices, aside from this system channel, there will be no other sources of automatic data collection.

Apps that have data automatically collected via Google Analytics include:

  • Personal Diary
  • Digital Scale+
  • NUS High Helper

With Google Analytics, in addition to general details listed above, some anonymous information about you may be automatically aggregated by Google. These data points include all above analytics information. In addition, generalised statistics for cohort of users, such as gender, demographics, interests etc.* may be indicated by Google.

*These additional data points by Google Analytics are fully anonymous and grouped such that they cannot be accessed by us on a per-person basis. These are only provided by Google if you have opted-in to data sharing via Google Ad Settings. Read Google’s Privacy Policy for more info.

Customer Support Activities

The act of sending a customer support request will include personal information such as your name and email, unless you intentionally anonymise it. In addition, your activity (buttons pressed, pages visited, errors encountered) within the app or service may be attached in the form of diagnostic logs via email. If you see no indication of logs attached, then no such information is attached and sent. These diagnostic logs may contain minor amounts of personal information, but you can always omit it from your submissions.

Note that sending a support email with diagnostic logs links your user activity with the email and name you provide. This linkage won’t be shared to third-parties, and will only be used for the purposes of customer support and improvement of apps/services. If you don’t remove these logs, the act of sending the email with attached logs constitutes your consent of this linkage.

Apps with Advertisements
  • Apps that serves Google Ads may serve personalised ads based on your Google activity, which is up to Google to decide upon which ads to serve. The apps do not allow Google to access your data.
  • Apps that serve customised ads by me may or may not be personalised, with anonymous information provided by Google Firebase/Analytics.

Relevant apps in this category: None

Apps Designed to Store/Access Personal Data
  • No data is sent or transferred outside of the app without your consent.
  • Any analytics/diagnostic information will not contain any personal data created/saved by the user.
  • If analytics/diagnostic information contains any other data (such as location etc.), it’ll not contain any information with a high degree of traceable information (eg. location will be rounded off to ±1° lat/long (~100km) of precision)
  • External 3rd party services will NOT be able to access any data you personally store.

For web services, the privacy policy follows that of the website.

All collected information are not shared to third-parties, except for the channel where data is collected. For example, data collected as a result of sending e-mails would need to be transmitted through mail servers, data collected via Google Analytics would need to be transmitted through Google Analytics, etc. These data are not shared across channels.

The usage of apps will be deemed as agreeing to this Privacy Policy and the Terms of Use. Note that since there’s no personal information collected about you except during customer support, this Privacy Policy may be updated without the ability to notify you. It is suggested that you check these pages occasionally for any updates if you are keen.
