Singapore MRT Privacy Policy

Roar Apps · Updated 25 October 2026

Singapore MRT provides offline maps, route planning, fares and timetables. You do not need an account. Route calculations and saved preferences are processed on your device.

Optional platform contributions

If you choose a platform letter, that tap sends your answer. Typed labels and “Varies” are sent only when you tap Submit. The report includes the departure station, line, adjacent next station, your answer, app version, operating system and a random app-installation identifier. It does not include your complete journey, name, contact details, GPS position or advertising identifier.

Roar Apps uses these reports to research and improve platform information. Cloudflare processes and stores them on our behalf. The database stores a hash of the installation identifier to prevent duplicate votes, rather than the raw identifier. Reports remain pseudonymous: reports from the same installation can be associated with each other. They are not linked to advertising, analytics profiles or accounts, and are not used for tracking or marketing.

Reports are unverified and privately reviewed; they are not shown to passengers or automatically used as travel advice. We retain them while needed for review and improving platform information, and remove identifiable report data when no longer needed. Network addresses are used transiently for abuse prevention and are not saved in the report database. Application request/body logging is disabled.

You may ignore the question, choose Not now, or choose Don’t ask again from its menu. Contribution prompts are hidden for the first 30 days of use, spaced at least seven days apart and limited to two unless you previously contributed, with a maximum of three. The optional contribution link remains available after the grace period. These choices do not affect route planning.

Analytics, crash reporting and advertising

The app uses Google Firebase Analytics, Firebase Crashlytics, Google AdMob and Google’s consent platform. Depending on your choices and applicable requirements, these services process app interactions, diagnostics, device or app identifiers, advertising data and network information to understand usage, diagnose crashes and provide or measure advertising. Their collection is separate from platform contributions. Advertising consent and Apple’s tracking permission are requested where applicable. Available advertising privacy choices can be reopened from the app’s About screen. Apple and Google handle store purchases; Roar Apps does not receive payment-card details.

See Google’s privacy policy and Cloudflare’s privacy policy for information about those providers.

Request deletion of platform reports

Email roarapps@gmail.com with the subject “Singapore MRT data deletion”. Tell us which platform report you want removed, including the station, line, next stop and approximate submission date; include your contribution identifier if available. Do not send names, GPS history or other unnecessary personal information.

We may ask for details needed to match the report and will explain if it cannot be identified. Once a request is matched, deletion covers the stored answer, station/line/next-stop context, installation-identifier hash, operating system, app version and receipt timestamps for that report. Reports otherwise remain while needed for private review and platform research; there is no fixed automatic expiry. Deleted data can remain in Cloudflare recovery backups for up to 30 days. Other providers’ analytics and advertising privacy controls are described above.

Your choices and contact

You can continue using the offline app without contributing. Uninstalling removes local contribution history; it does not automatically remove previously submitted reports. To ask about access, correction or deletion of information, contact roarapps@gmail.com. We may need information that lets us identify a report, and we do not ask for unnecessary personal details. Contact us if you believe a child has supplied personal information. We do not knowingly collect personal information from children under 13.

We may update this policy as the service changes. The date above identifies the latest revision.
