DoubleHuat ("we", "our", "the Service") is a free statistical research platform for Singapore Pools 4D and TOTO lottery data. This Privacy Policy explains how we collect, use and protect your personal data in accordance with Singapore's Personal Data Protection Act 2012 (PDPA). By using the Service, you agree to the practices described in this policy.
When you register, we collect your name and email address. When you use the Service, we collect numbers you save to your tracker and your usage activity. We do not collect payment information — the Service is free and we do not process any financial transactions.
We use session cookies to keep you logged in. We also display advertisements through Google AdSense and similar ad networks. These networks may use cookies to show you relevant ads based on your browsing activity. You can opt out of personalised advertising at google.com/settings/ads. We do not control the cookies placed by advertising partners.
Your data is used solely to manage your account, provide the Service, and send account-related emails such as email verification and password resets. We do not use your data for marketing purposes and we do not sell your data to third parties.
We use Google AdSense and similar ad networks to display advertisements. These services operate under their own privacy policies. All lottery draw data is sourced from publicly available Singapore Pools historical results. We are not affiliated with or endorsed by Singapore Pools (Private) Limited.
We do not sell, rent or share your personal data with third parties except where required by Singapore law or a valid court order. Advertising partners may receive anonymised, aggregated data as part of standard ad-serving operations.
Under the PDPA, you have the right to request access to or correction of your personal data held by us. To exercise these rights, contact us at support@doublehuat.com. We will respond within 10 business days. You may also request deletion of your account and associated data at any time.
We implement reasonable security measures to protect your personal data from unauthorised access, disclosure or loss. Passwords are stored as one-way cryptographic hashes and are never stored in plain text. However, no internet service can guarantee absolute security.
The Service is intended solely for users who are 18 years of age or older. By registering, you confirm that you meet this requirement. If we become aware that a user is under 18, we will delete their account and associated data.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Continued use of the Service after changes are posted constitutes acceptance of the updated policy.
For any questions about this Privacy Policy or your personal data, contact us at support@doublehuat.com. We respond within 5 business days. Note: this contact email will be updated once our business incorporation is complete.
This Privacy Policy complies with Singapore's Personal Data Protection Act 2012 (PDPA) and applicable advertising regulations.
