5. Cross-Border Data Transfers

Your personal information may be transferred to and processed in countries outside of Australia, including the United States, where our third-party service providers (primarily Google/Firebase) maintain servers. These countries may have different data protection laws than Australia.

Before transferring personal information overseas, we take reasonable steps to ensure the overseas recipient handles your information in accordance with the Australian Privacy Principles, as required under APP 8. By using the Service, you consent to this transfer.

6. Data Storage, Retention, and Security

6.1 Storage

Your data is stored on Firebase (Google Cloud Platform) servers. We rely on Google’s infrastructure security, which includes physical security, encryption, and access controls.

6.2 Retention

  • Active accounts: we retain your data for as long as your account remains active.
  • Deleted accounts: when you delete your account, we will delete or anonymise your personal information within 30 days. Some data may be retained in encrypted backups for up to 90 days before being permanently removed.
  • Contact form submissions: retained for up to 12 months after resolution of your enquiry.
  • Aggregated/anonymised data: may be retained indefinitely for analytical purposes, as it cannot be used to identify you.
  • Legal holds: data may be retained beyond these periods if required by law or to resolve disputes.

6.3 Security measures

We take reasonable steps to protect your information, including:

  • Encryption of data in transit (HTTPS/TLS) and at rest.
  • Firebase Authentication for secure account access with hashed passwords.
  • Firestore security rules to restrict data access to authorised users only.
  • Regular review of our data collection, storage, and processing practices.
  • Restricting access to personal information to those who need it to operate the Service.

While we strive to protect your information using commercially reasonable measures, no method of electronic storage or transmission is 100% secure. We cannot guarantee absolute security, and you use the Service at your own risk.

7. Data Breach Notification

In accordance with the Notifiable Data Breaches (NDB) scheme under Part IIIC of the Privacy Act 1988, if we become aware of a data breach that is likely to result in serious harm to any individual whose personal information is involved, we will:

  • Take immediate steps to contain the breach and mitigate any harm.
