Privacy Policy

Last updated: 11 April 2026

1. Who We Are

COEkaki ("we", "us", "our") operates the website coekaki.com, a Singapore-based platform that tracks Certificate of Entitlement (COE) prices, trends, and provides car ownership tools. This Privacy Policy explains how we collect, use, disclose, and protect your personal data in accordance with the Singapore Personal Data Protection Act 2012 (PDPA).

2. Data We Collect

Account Information

When you register, we collect your name and email address. If you sign in via Google, we receive your Google profile name, email, and avatar.

Usage Data

When Google Analytics is enabled and analytics consent is given, it records usage information such as pages visited and device information. The site also stores IP addresses with contact form submissions and some security records.

Subscription & Payment Data

If you subscribe to a paid plan, payment processing is handled entirely by Stripe. We store your Stripe customer ID and subscription status but never store your credit card number, CVV, or full card details.

Cookies

We use essential cookies (session, CSRF token, theme preference), analytics cookies (Google Analytics), and advertising cookies (Google AdSense). You can manage cookie preferences via our consent banner.

Price Alerts & Predictions

If you set up price alerts or submit predictions, we store your alert thresholds, category preferences, and prediction values linked to your account.

3. How We Use Your Data

  • Provide and improve our services (COE tracking, calculators, alerts)
  • Send you price alerts and bidding notifications you opted into
  • Send email digests and newsletters (with your consent)
  • Process subscription payments via Stripe
  • Analyse site usage to improve performance and content
  • Prevent fraud and enforce our terms

We do not sell your personal data to third parties.

4. Third-Party Services

We share data with these service providers who process data on our behalf:

5. Data Retention

Account deletion removes the account and its linked records from the application database. For a verified email address, it also removes matching newsletter, contact and lead records. This action does not itself erase external service records or existing backups. Use the contact form for questions about retained data.

6. Your Rights Under PDPA

You have the right to:

  • Access — Request a copy of your personal data
  • Correction — Update inaccurate personal data via your profile page
  • Withdrawal of consent — Opt out of marketing emails at any time
  • Deletion — Request deletion of your account and associated data

To exercise these rights, visit your profile page or use the contact form below.

7. Data Security

The application uses password hashing, CSRF protection and rate limiting. API keys are stored as hashes. Transport encryption depends on accessing the site over HTTPS.

8. Children's Privacy

Our service is not directed to individuals under 13. We do not knowingly collect personal data from children.

9. Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the site constitutes acceptance of the updated policy.
