Privacy Policy

Last updated: 16 August 2026

This Privacy Policy explains how the ChiongAh mobile application (“ChiongAh”, “the app”, “we”, “us”) handles information when you use it. ChiongAh is published by BeaconWeaves and helps you get around Singapore using public transport.

We built ChiongAh to be private by default. You do not create an account, and we do not ask for your name, email address, or phone number.

The short version

  • No account, no sign-in. ChiongAh works anonymously.
  • Your precise location never leaves your device. It is used on-device to show nearby stops and plan journeys.
  • Transit data comes from Singapore’s LTA DataMall. Those requests do not include your identity or your GPS position.
  • Analytics and crash reporting are off until you consent, and are limited to diagnostics and product-usage information — never used to track you across other apps or websites.
  • Ads are non-personalized and shown only where required, and can be removed entirely with a one-time in-app purchase.
  • Your favourites, saved places, and settings stay on your device.

Location

If you grant permission, ChiongAh uses your device location while you are using the app (“When In Use” only — never in the background). Location is used to:

  • show bus stops and MRT stations near you, and
  • set the starting point when you plan a journey.

Your precise GPS coordinates are processed entirely on your device and are not transmitted to us or to any server. Nearby-stop lookups and journey planning run against transit data stored on the device. The only location values ever sent over the network are the fixed public coordinates of a bus stop or station (for example, to look up nearby bicycle parking) — never your own position.

You can grant, deny, or revoke location access at any time in iOS Settings → Privacy & Security → Location Services → ChiongAh. ChiongAh remains usable without location access; you can search for stops manually.

Transit data (LTA DataMall)

ChiongAh retrieves live and reference transit information — bus arrivals, bus and train routes, service alerts, facility and crowding information — from LTA DataMall, a service operated by Singapore’s Land Transport Authority. These requests are authenticated with an application key that belongs to the app, not to you, and do not include any personal information or your location.

Analytics and diagnostics

To understand which features are useful and to fix crashes and performance problems, ChiongAh can use Google Firebase (Analytics, Crashlytics, and Performance Monitoring) and Apple’s on-device MetricKit diagnostics.

  • Analytics collection is disabled when the app launches and is enabled only if you provide consent through the in-app consent prompt described below.
  • Analytics events describe product interactions (for example, viewing a stop, adding a favourite, or planning a journey). Some events include public transit identifiers such as a bus-stop code, station code, or service number. Paired with a timestamp these can act as a coarse-location signal — but they are public network references, not your GPS position.
  • Crash and performance data (diagnostic logs, device model, OS version) help us diagnose problems.

This information is not linked to your identity (you have no account) and is not used to track you across other companies’ apps or websites.

Advertising

ChiongAh may show a banner advertisement via Google AdMob. Advertising is handled as follows:

  • Where required (for example, for users in the EEA/UK), a consent prompt is shown using Google’s User Messaging Platform before any ads or analytics are enabled. Your choice is respected.
  • Ads are requested as non-personalized — they are not tailored to you using your personal data or interests.
  • ChiongAh does not display Apple’s App Tracking Transparency prompt because it does not track you across other apps.
  • Apple’s SKAdNetwork may be used for privacy-preserving measurement of ad installs; this does not identify you.

You can remove ads permanently with the one-time in-app purchase described below.

Purchases

ChiongAh offers a one-time in-app purchase (a “premium unlock” that removes ads). Payment is processed entirely by Apple through the App Store. ChiongAh never sees or stores your payment card, billing address, or other financial details. Your purchase status is determined on-device from your App Store transactions, and can be restored via Restore Purchases.

Information stored on your device

The following is stored locally on your device only and is not uploaded to us or synced to any cloud service:

  • Favourites — the stops and services you save.
  • Saved places — such as home or work locations you add.
  • Settings and preferences — accessibility, notification, and display options.

Favourites are kept in a shared app container so that ChiongAh’s widgets and Siri shortcuts can display them. Deleting the app removes all of this data from your device.

What we do not do

  • We do not require or create an account.
  • We do not collect your name, email, phone number, or contacts.
  • We do not transmit or store your precise GPS location.
  • We do not sell your personal information.
  • We do not track you across other apps or websites.

Your choices

  • Location: manage in iOS Settings (see above).
  • Analytics and ads consent: you can change your consent choice from within the app; declining keeps analytics disabled and limits ads to non-personalized.
  • Remove ads: purchase the premium unlock.
  • Delete your data: delete the app to remove all locally stored data.

Third-party services

ChiongAh relies on the following third parties. Their handling of data is governed by their own policies:

  • Land Transport Authority (LTA DataMall) — transit data.
  • Google (Firebase and AdMob) — analytics, crash reporting, performance, and advertising. See Google’s Privacy Policy.
  • Apple — App Store, payments, and on-device diagnostics. See Apple’s Privacy Policy.

Children

ChiongAh is a general-audience utility and is not directed at children. We do not knowingly collect personal information from children.

Data retention

Because ChiongAh does not maintain user accounts, we do not hold a personal profile about you. Data stored on your device remains until you delete it or uninstall the app. Diagnostic and analytics data collected (with consent) through Google and Apple is retained according to those providers’ policies.

Your rights

ChiongAh is operated from Singapore and handles personal data in line with Singapore’s Personal Data Protection Act (PDPA). Depending on where you live, you may have rights to access, correct, or request deletion of personal data. Since we do not hold an account or profile that identifies you, most data is under your direct control on your device; for anything else, contact us using the details below.

Changes to this policy

We may update this Privacy Policy from time to time. Material changes will be reflected here with a new “Last updated” date. Continued use of the app after an update means you accept the revised policy.
