1. About this statement

This Privacy Statement explains how Water Software Solutions Ltd, trading as Watercalcs (we, us, our), collects, uses, discloses, and protects personal information, in accordance with the Privacy Act 2020. By using the Service you agree to this statement.

2. Information we collect

We may collect:

  • contact and account information you give us, such as your name and email address, when you create a Premium account or join our waitlist;
  • payment information, which is collected and processed by our payment provider, Stripe — we do not store your full card details; and
  • technical and usage information collected automatically when you use the site, such as device and browser information, IP address, and the pages or tools used, including through cookies and similar technologies.

You do not need to provide personal information to use the free calculators.

3. How and why we use your information

We use personal information to:

  • provide and operate the Service;
  • create and manage accounts and subscriptions;
  • process payments;
  • respond to enquiries and send service or waitlist communications;
  • improve and secure the Service; and
  • meet our legal obligations.

We will only use it for the purposes for which it was collected, related purposes you would reasonably expect, or as otherwise permitted by law.

4. Disclosure

We may disclose personal information to third-party providers who help us run the Service — for example, hosting, authentication, database, payment, analytics, and email providers. Some of these providers, and the servers on which information is stored, are located outside New Zealand (including in the United States). Where we disclose information overseas, we take reasonable steps to ensure comparable safeguards consistent with the Privacy Act 2020. We do not sell your personal information.

5. Storage and security

We take reasonable steps to protect personal information from loss, misuse, and unauthorised access, including by using reputable service providers. No system is completely secure, and we cannot guarantee absolute security.

6. Cookies

We use cookies and similar technologies to operate the site, remember preferences, and understand usage. You can control cookies through your browser settings; disabling them may affect how the site works.

7. Accessing and correcting your information

Under the Privacy Act 2020 you have the right to ask for access to the personal information we hold about you and to request corrections. To make a request, contact us using the details below. We may need to verify your identity before responding.

8. Retention

We keep personal information only for as long as needed for the purposes described, or as required by law, after which we will delete or de-identify it.
