Privacy Policy
Last updated: 10 November 2026
Sigma Maths ("we") runs the Sigma platform at app.sigmaths.org, which teachers and their assistants use to run maths classes and keep parents informed. This policy explains what information we hold and how we use it.
Information we hold
- Student details entered by the teacher or through our registration form: name, school, year group, class, and student ID.
- Parent or guardian contact details: name, WhatsApp number and email address.
- Learning records: attendance, homework and quiz marks, lessons covered, and teacher comments.
- Staff accounts: name, username and an encrypted password, plus a log of actions in the platform for security.
How we use it
Only to teach and follow up students: planning lessons, setting homework and tests, and sending progress reports and reminders to students and parents by WhatsApp, email and Google Classroom. We do not sell information or use it for advertising.
Google services
The platform runs on Google Workspace services (Google Sheets, Drive, Classroom, Calendar and Gmail) under the teacher's own Google account. With the teacher's permission it reads the teacher's Classroom courses and rosters and creates coursework, materials and announcements in them. Data obtained through Google APIs is used only to provide these features, is not shared with third parties, and is not used to develop or train AI models. Our use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Who can see it
The teacher who owns the class and the assistants the teacher authorises, each limited to the permissions the teacher gives them. Parents receive reports about their own child only.
How long we keep it
For as long as the student studies with us, and then for a reasonable period for records, unless deletion is requested sooner.
Your choices
Parents and students can ask to see, correct or delete their information, or stop receiving messages, by contacting us below.
