6. Data Sharing and Disclosure

We do not sell your Personal Data. We may share or disclose your information in the following circumstances:

  • Service Providers: We may share your information with third-party vendors, consultants, and other service providers who perform services on our behalf (e.g., hosting providers, data analytics providers, payment processors, customer support tools). These service providers are contractually bound to protect your information, use it only for the purposes for which it was disclosed, and provide a standard of protection to the Personal Data so transferred that is comparable to the protection under the PDPA.
  • Affiliates: We may share information with our Affiliates, in which case we will require those affiliates to honor this Privacy Policy.
  • Legal Obligations and Rights: We may disclose your information if required to do so by law or in the good faith belief that such action is necessary to (i) comply with a legal obligation or governmental request; (ii) protect and defend our rights or property; (iii) prevent or investigate possible wrongdoing in connection with the Service; or (iv) protect the personal safety of users of the Service or the public.
  • Business Transfers: If the Company is involved in a merger, acquisition, or asset sale, your Personal Data may be transferred. We will provide notice before your Personal Data is transferred and becomes subject to a different Privacy Policy.

If you click on a third-party link, you will be directed to that third party’s site. We strongly advise you to review the Privacy Policy of every site you visit. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services. Our Service may also make available content or services from Third-party Social Media Services; your interaction with these is governed by their respective privacy policies.

7. International Data Transfers

Your information, including Personal Data, may be transferred to and maintained on computers located outside of your state, province, country, or other governmental jurisdiction where the data protection laws may differ from those in your jurisdiction. As our Company is based in Singapore, this includes transfers to Singapore if you are located elsewhere. If you are located outside Singapore and choose to provide information to us, please note that we transfer the data, including Personal Data, to Singapore and process it there.

When transferring Personal Data out of Singapore, We will take all steps reasonably necessary to ensure that your data is treated securely and in accordance with this Privacy Policy and the PDPA. This includes ensuring that the recipient country or territory has data protection laws comparable to Singapore’s PDPA, or that other appropriate safeguards are in place, such as binding corporate rules or contractual clauses ensuring a comparable standard of protection.

8. Data Retention

We will retain your Personal Data only for as long as is necessary for the purposes set out in this Privacy Policy and for which it was collected, unless a longer retention period is required or permitted by law (such as for tax, accounting, or other legal requirements) or for business purposes.

The criteria used to determine our retention periods include:

  • The length of time we have an ongoing relationship with you and provide the Service to you.
  • Whether there is a legal or business obligation to which we are subject.
  • Whether retention is advisable in light of our legal position (such as in regard to applicable statutes of limitations, litigation, or regulatory investigations).

We implement data lifecycle management procedures, including regular data purging strategies where appropriate, to maintain data timeliness and comply with storage policies and the PDPA’s retention limitation principle. Query logs related to the Service adopt short-term retention policies and are maintained in a manner that does not directly link them to user identity information for routine operational purposes.

9. Your Data Protection Rights (Under PDPA)

In accordance with the PDPA, you have certain rights regarding your Personal Data that we process. These rights may include:

  • The right to access: You have the right to request access to your Personal Data that is in our possession or under our control and information about the ways in which your Personal Data has been or may have been used or disclosed by us within a year before the date of the request.
  • The right to correction (rectification): You have the right to request that we correct any error or omission in your Personal Data that is in our possession or under our control.
  • The right to withdraw consent: If we are processing your Personal Data based on your consent, you have the right to withdraw your consent at any time. Withdrawing your consent will not affect the lawfulness of any processing we conducted prior to your withdrawal, nor will it affect processing of your Personal Data conducted in reliance on lawful processing grounds other than consent. Please note that withdrawing consent may affect our ability to provide the Service to you.
  • The right to erasure (right to be forgotten): You may have the right to request that we erase your Personal Data, under certain conditions as permitted by law.
  • The right to restrict processing: You may have the right to request that we restrict the processing of your Personal Data, under certain conditions.
  • The right to object to processing: You may have the right to object to our processing of your Personal Data, under certain conditions.
  • The right to data portability: You may have the right to request that we transfer the data that we have collected to another organization, or directly to you, under certain conditions.

To exercise any of these rights, please contact our Data Protection Officer using the contact details provided in Section 15. We will respond to your request in accordance with the PDPA and other applicable data protection laws. We may need to verify your identity before processing your request.

You may also have the right to lodge a complaint with the Personal Data Protection Commission (PDPC) of Singapore if you believe that your data protection rights have been breached.

10. Data Security

We are committed to protecting the security of your Personal Data.

10.1. General Measures: We implement and maintain commercially reasonable administrative, physical, and technical safeguards, constituting reasonable security arrangements as required by the PDPA, designed to protect the security, confidentiality, and integrity of Your Data (and particularly Personal Data) from unauthorized access, use, modification, disclosure, or similar risks.

10.2. Specific Mechanisms: These measures include, but are not limited to:

  • Employing strict privacy protection protocols for data storage and handling.
  • Storing all phone numbers processed through the Service using industry-standard hashing algorithms (such as SHA-256) with unique salts for each value, designed to prevent the reverse-engineering of original numbers.
  • Ensuring that Our database primarily stores number hash values, status information, and timestamps, without retaining identifiable plaintext phone numbers beyond the processing necessary to provide the Service.
  • Implementing data lifecycle management procedures, including regular data purging strategies where appropriate, to maintain data timeliness and comply with storage policies.
  • Adopting short-term retention policies for query logs, which are maintained in a manner that does not directly link them to user identity information for routine operational purposes.

Data Breach Notification: In the event of a data breach affecting your Personal Data under our control that is notifiable under the PDPA (i.e., is assessed to be likely to result in significant harm to affected individuals or is of a significant scale), we will notify the PDPC and affected individuals in accordance with PDPA requirements.

10.4. Limitation: While we strive to use commercially acceptable means to protect your Personal Data, we cannot guarantee its absolute security. No method of transmission over the Internet, or method of electronic storage, is 100% secure.
