Teach Me Maths Limited ("we", "us", or "our") operates the web platform at https://teachmemaths.co.nz (the "Service"). This Privacy Policy explains what personal information we collect, why we collect it, how we store it, who can access it, and how you can request its deletion. We comply with the New Zealand Privacy Act 2020 and the Information Privacy Principles it sets out.
This Privacy Policy should be read alongside our Terms of Service.
We collect the following types of personal information:
Account Information
Learning Progress Data
Class & School Information
School License Information (for subscribing schools)
Feedback form (optional)
We do not collect information for marketing, profiling, or sale to third parties. We do not use your data to train external AI models or sell it to advertisers.
Hosting: Your data is stored in a secure cloud database hosted by Base44, our platform provider. Data is stored and processed on servers located in the United States. By using the Service, you acknowledge that your personal data will be transferred to and processed in the United States. We take reasonable steps to ensure that this cross-border transfer is subject to appropriate safeguards consistent with the requirements of the New Zealand Privacy Act 2020. All data in transit is encrypted using HTTPS/TLS. The platform enforces HTTP Strict Transport Security (HSTS) to prevent downgrade attacks.
Authentication: You can sign in with Google (OAuth 2.0) or with an email address and password, verified by an emailed code. Passwords are handled securely by our platform provider, Base44, and are never visible to Teach Me Maths. Session tokens are stored as strictly necessary cookies and are not shared with third parties.
Access controls: The platform enforces role-based access control. Students can only view their own progress data. Teachers can view progress data for students in their own classes. Administrators can view data across their school. Access is enforced at both the application routing layer and the database row-level security layer.
No third-party tracking: We do not use Google Analytics, advertising pixels, or third-party tracking cookies. Google is involved only if you choose to sign in with Google (Google shares your email address and name with us) or a teacher uses the Google Classroom import.
We do not share personal information with any other third parties. We do not sell or rent personal data under any circumstances.
Active accounts: Your data is retained for as long as your account is active and, for school-licensed users, for the duration of the active school license.
After a school license expires or is terminated: Student progress data, class membership, and assignment records linked to that school are retained until 31 March of the following year (so the school can renew without losing anything), then permanently deleted.
Individual free accounts: If you stop using the Service, your data is retained for 12 months of inactivity, then deleted.
On request: You or your school administrator can request deletion of your data at any time (see Section 6 below).
We do not retain personal information longer than is necessary for the purposes for which it was collected, in accordance with Information Privacy Principle 9.
Under the New Zealand Privacy Act 2020, you have the right to:
To exercise any of these rights, please contact us at hello@teachmemaths.co.nz. We will respond to your request within 20 working days, as required by the Privacy Act.
For school accounts: A school administrator (e.g., principal, DP, or IT manager) may request bulk deletion of all student data for their school. This request should be sent from an official school email address.
In the event of a confirmed security incident or data breach impacting personal information, we will notify the designated contact at affected subscribing schools without undue delay to enable compliance with statutory reporting obligations under the Privacy Act 2020. This notification will include:
We will also notify the Office of the Privacy Commissioner where required under the Privacy Act 2020.
The Service uses strictly necessary cookies for authentication (keeping you logged in). These cookies are required for the Service to function and are not used for tracking or advertising. We do not use analytics cookies, advertising cookies, or third-party tracking cookies. No cookie consent banner is displayed because no non-essential cookies are set.
Google OAuth 2.0: Used for account authentication. When you sign in with Google, Google shares your email address and name with us. Google's use of this information is governed by Google's own Privacy Policy. We do not share any additional data back to Google.
Google Classroom (optional): If a teacher chooses to import a class, we read the course name and student roster (names and email addresses) from Google Classroom with the teacher's permission. We do not write anything back to Google Classroom. School IT administrators can see exactly which permissions are requested, and how to approve them, in our Google Classroom guide for IT administrators.
Google API data (Limited Use): Teach Me Maths' use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Data from Google Classroom is used only to set up and keep the teacher's Teach Me Maths class in step with their Classroom course. It is never used for advertising, never sold, never used to train AI models, and never shared with anyone else except our platform provider (Base44) as needed to run the Service.
Base44 (platform provider): Provides the database hosting, application hosting, email-and-password sign-in, system emails, and infrastructure for the Service. Base44 acts as a subprocessor and processes personal data only on our behalf. Base44 hosts data on servers located in the United States. For information about Base44's security practices, see https://base44.com/security.
KaTeX (CDN): Used to render mathematical notation. Loaded from jsdelivr CDN. No personal data is sent to this service — it is a client-side rendering library only.
We do not use any other third-party services that process personal data.
Teach Me Maths is designed for use in secondary schools (typically Years 9–13, ages 13–18). Subscribing schools act in loco parentis and are responsible for obtaining any parental notification or consent required under their internal policies before authorising students under the age of 16 to use the Service. We do not knowingly collect personal information from students outside of an authorised school context or individual free account signup.
We may update this Privacy Policy from time to time. We will notify users and subscribing schools of significant changes via email or a prominent notice on the Service. Continued use of the platform after changes take effect constitutes acceptance of the updated policy.
For any questions about this Privacy Policy, or to request access, correction, or deletion of your personal information, please contact us at:
If you are not satisfied with our response, you may lodge a complaint with the Office of the Privacy Commissioner at www.privacy.org.nz or by calling 0800 803 904.
