Privacy Policy

Senary Maths is run by Senary Learning, the data controller for the personal information described here. For schools, we process pupils’ information on the school’s behalf and follow its instructions. Reach us through ourContact us page.

• Pupils: first name, surname, level, student code, school or class, and maths results (answers, speed, stars, ranks and certificates).
• Parents: title, name, email, phone, country, children’s details, subscription status and marketing choice.
• Teachers and schools: name, email, school name and address, office email, approximate pupil numbers, classes and tasks set.
• Messages: messages parents send to teachers, and Contact us enquiries.
• Consent records: when you agreed to our terms and your marketing choice.
• Device: basic technical information (such as IP address and browser) needed to keep you logged in and the app secure.

We do not receive or store full card or mobile money details.

• To provide the app — games, adaptive difficulty, progress, logins and certificates (to perform our agreement with you).
• To manage subscriptions and answer enquiries (agreement, and legal obligations such as tax records).
• To keep the app safe and prevent fraud and misuse (legitimate interests).
• To improve our maths content, using results in combined form (legitimate interests).
• Marketing emails about Senary Learning products and services only — sent only if you opted in (consent).

Some questions and practice plans are produced with an AI service. We send it only what it needs, such as a level and which facts were tricky — never names, contact details or passwords. We never use children’s information for marketing or profiling, and never send marketing to pupils.

• the pupil, their parent or guardian, and teachers at the pupil’s own school;
• service providers who host the app, send email and provide AI, only to deliver those services;
• Paddle, our Merchant of Record, to sell subscriptions, take payments, handle tax and issue invoices;
• professional advisers, such as lawyers and accountants, where needed;
• authorities, only where the law requires it or a child is at risk.

We never sell or rent personal information, or share it with other companies for their marketing.

Our service providers may store information outside your country. Where that happens, we use providers with strong safeguards, such as contractual protections, as required by the data protection law that applies to you.

Information is encrypted in transit and stored on secure cloud servers. Each school’s data is kept separate, access is limited to people who need it, and passwords are protected so that even we cannot read them. If a data breach affects you, we will tell you and the relevant regulator as the law requires.

We use only what is needed to keep you logged in and remember your country. We do not use advertising or tracking cookies. See ourCookies Declaration.

• Account and progress information: while the account is in use.
• When an account closes: deleted or anonymised within 90 days.
• Payment and tax records: as long as the law requires (usually up to 7 years).
• Contact enquiries: up to 2 years.
• Marketing choice: until you change it or close your account.

Depending on where you live, you can ask to see, correct, delete or download your information, or your child’s; limit or object to how it is used; and withdraw consent (including to marketing) at any time. Senary Learning is registered in the United Kingdom, so we follow the UK GDPR and the Data Protection Act 2018, as well as the data protection laws of the countries we serve, such as Zambia’s Data Protection Act, Nigeria’s Data Protection Act, Kenya’s Data Protection Act, South Africa’s POPIA and Ghana’s Data Protection Act. We reply within one month. You can complain to the UK Information Commissioner’s Office (ico.org.uk) or to your national data protection authority.

If we make important changes, we will update the date at the top and let account holders know.
