Privacy Policy

What we collect

• Email address — only if you create an account. You can sign in with an email sign-in link or with Google. If you use Google, Google provides us with the email address of the account you choose.
• Notification (push) subscriptions — if you turn on new-sale alerts for an estate, we store the technical details your device generates so notifications can be delivered: a push endpoint URL and two encryption keys, linked to your account and to the estates you follow.
• Saved estates (favourites) — if you save estates while signed in, the list of estate identifiers is stored with your account. If you are not signed in, favourites stay only in your browser and are never sent to us.
• Anonymous usage statistics — we use Vercel Web Analytics to count page views and understand which pages are used. This is aggregate and anonymous: no tracking cookies are set, and we do not build advertising profiles.

What we do not do

• We do not sell or rent your personal data.
• We do not run advertising or cross-site tracking, and the app contains no advertising SDKs.
• We do not collect your name, phone number, home address, or payment details.
• We do not track your precise location.

How we use it

• To sign you in and sync your favourites and alerts across your devices.
• To send the new-sale notifications you have subscribed to.
• To understand overall usage and keep the service reliable, using anonymous analytics.

Where it is stored

Your account email, favourites, and push subscriptions are stored in our database and authentication service, provided by Supabase, hosted in the Singapore (ap-southeast-1) region. The application is hosted on Vercel.

Third parties

We share data with the following service providers only as needed to run the service:

• Supabase — database and authentication. Stores your email, favourites, and push subscription records, and sends sign-in emails.
• Vercel — application hosting and anonymous usage analytics.
• Google — identity provider, used only if you choose to sign in with Google.
• The push service used by your browser or device (for example, one operated by your browser or device vendor) — receives the notification we send so that it can be delivered to your device. This is a standard part of web push notifications.

Map tiles are loaded in your browser from OpenStreetMap. When your browser requests map images, OpenStreetMap receives standard request information such as your IP address, as happens with any website you visit.

Cookies

We use only essential cookies needed to keep you signed in (a session cookie set by our authentication provider, Supabase). We do not use advertising or cross-site tracking cookies, and our analytics are cookieless. If you never sign in, no authentication cookie is set.

Data source

The property prices we display come from data.gov.sg (HDB resale transaction open data), and location data comes from OneMap (Singapore Land Authority). This is public government data about properties, not about you. SingBuDong is an independent service and is not affiliated with, endorsed by, or connected to HDB, data.gov.sg, or the Government of Singapore.

Your choices

• Sign out at any time from Settings.
• Turn off alerts — remove individual estate alerts, or turn off all alerts on a device, from Settings.
• Remove favourites — delete saved estates at any time.
• Clear local data — the Reset local data button in Settings clears your settings and locally saved estates from this browser.
• Delete your account and data — email us at wygxaa@gmail.com and we will delete your account, favourites, and push subscriptions.

Retention

We keep your account data for as long as your account exists. When you ask us to delete your account, we remove your email, favourites, and push subscriptions. Anonymous analytics are retained in aggregate by Vercel and cannot be linked back to you.

Children

SingBuDong is not directed at children, and we do not knowingly collect personal data from children.

Changes

We may update this policy. Material changes will be reflected on this page with a new effective date.
