PDPA and data protection
This is general information, not legal advice. Your legal adviser has the final word.
Personal Data Protection Act 2012 (PDPA)
Sets the rules for collecting, using and disclosing personal data in Singapore, including notifying data breaches. We plan consent, purpose limitation and protection into the app from the first sprint.

The Personal Data Protection Commission (PDPC) administers the PDPA and publishes advisory guidelines for organisations.

Frequently asked questions
App development in Singapore: before you book a call.
Do you have an office in Singapore?
Yes. UnFoldMart's Singapore office is at 8 Kaki Bukit Road 2, Ruby, #02-08, Singapore 417841. Workshops, design reviews and weekly check-ins with Singapore clients take place by video, in English.
How much does it cost to build an app in Singapore?
Pricing is custom. Cost depends on platforms, screens and features, integrations, design depth, compliance needs and your timeline. After a short brief and a free 30-minute call, you get a written estimate.
How long does it take to build an app?
Typically: discovery 1 to 3 weeks, design 2 to 5 weeks, build 8 to 16 weeks for a first version, testing and store release 1 to 3 weeks. These are ranges, not guarantees.
Should we build a native app or use Flutter or React Native?
Native (Swift for iOS, Kotlin for Android) suits top performance and deep device features. Cross-platform (Flutter or React Native) shares one codebase and usually reaches both stores faster. We recommend one in discovery.
How do you handle the PDPA?
We plan consent, purpose limitation, protection and retention into the app from the first sprint, and collect only the data the app needs. Your legal adviser has the final word.
Do you build apps for financial companies in Singapore?
Yes, we build customer and internal apps for financial companies. Security testing runs before every release, and we document how the app handles data and access so your risk team can review it, for example against the MAS Technology Risk Management Guidelines.
Can you connect PayNow and other payment methods?
Yes. Singapore users commonly pay with PayNow, cards and wallets such as Apple Pay and Google Pay. We connect the methods your payment provider supports.
Can one app serve users across Southeast Asia?
Yes. We set up languages, currencies and regional settings so one app can grow from Singapore into other markets without a rebuild.
Who works on our project, and how do we communicate?
Projects are led by UnFoldMart from our international offices, with a small dedicated team. Calls are by video, in English, with a demo after each sprint.
Can you take over an existing app?
Yes. We start with a review of the code, the store listings and the backend, then fix, upgrade or rebuild in steps, so your app stays available.
