1. Who is responsible
Kani Math is operated by Mohammad M. AbuZer, a sole proprietor based in Jordan, who decides how the information described here is used and is responsible for it (the “data controller”). You can reach us about anything in this policy at the address at the bottom of this page.
2. What we collect
We collect the information needed to run the program: a learner profile (display name, age, level, avatar choice), practice and lesson activity, and any messages you send us. Learner and parent profiles need no email address, password or phone number; teacher accounts sign in with an email address and a password. If you take the placement exam on our website, it asks for a parent’s name, and the child’s name and age if you add them, and we keep them with the result. If you buy a subscription, we also record the purchase: which plan, when it started and renews, its status, and the reference the app store or payment provider gives it. We never receive or store your full card details. If you pay by bank transfer or CliQ, we see the payer’s name and the transfer reference that our bank shows us. If a purchase does not go through, we record technical details of the failure (the store, the plan, the error code, the app version, the device model and system version, and the country) so we can fix payment problems. During a test of our own speech recogniser, we also record what the microphone picks up while a learner answers in Shout mode (every learner, in their own drills and in homework set by a teacher), and keep it with the question, what the recogniser heard and details of the device. Only the staff who operate the platform can listen to these recordings, which are kept on our servers and deleted automatically after 30 days, or sooner if you ask us.
3. How we use it
We use the information to deliver lessons, track progress, generate dashboards for parents and teachers, send service updates, and improve the product. We do not sell personal information, and we do not run third-party advertising profiles against learner activity.
4. Where it is stored
Our servers run in a DigitalOcean data center in Frankfurt, Germany, and connections to them are encrypted. We keep a profile and its progress until it is deleted, from the app or at your request. Records of purchases are kept for as long as tax and accounting rules require.
5. Who can see it
Inside Kani Math, learner data is visible to a parent or guardian using the learner’s profile, the teacher of a class the learner joins in the app (once that teacher approves them), and the small number of staff who operate the platform. A learner’s display name, avatar, country and scores also appear on the public leaderboards, which anyone can see, unless “Show me on public leaderboards” is switched off when editing the profile. We share data with service providers only to the extent needed to run the service.
6. Children’s data
A core audience is school-age learners, so we minimize what is collected from accounts identified as children. A child profile holds a display name (a nickname works), an age, a level, an avatar, a language and practice activity — no email, password or phone number. Kani Math is designed to be set up and supervised by a parent, guardian or teacher, and that adult chooses what goes into the profile. It can be deleted, with all of its progress, from the app at any time or by writing to the address below.
7. Cookies and local storage
We use cookies and browser storage for sign-in sessions, language preference and remembering your last lesson. We also use Google Analytics to count visits and see which pages and features are used; on the web it sets its own cookies on our domain. We do not show advertising in Kani Math.
8. Third-party services
We rely on a short list of vendors for hosting, email delivery, analytics, error monitoring and payment processing. Subscriptions bought in the mobile apps are processed by Apple or Google under their own privacy policies; they tell us that a subscription exists and whether it is active, and we tell them nothing about the learner. Payments on our website are handled by the payment provider shown at checkout, which receives only what it needs to take the payment. If Shout mode is switched on, spoken answers are recognised by the speech service built into the browser or the device, which may send the audio to its provider, such as Google or Apple, under that provider’s own privacy policy. Each vendor only receives the data it needs to perform its function.
Payments on our website are processed by Paddle.com, our reseller and Merchant of Record. Paddle receives the details it needs to take the payment and charge the right tax, such as your email address, country and payment details, and handles them under its own privacy notice. We never receive your card details: Paddle tells us which plan was bought and whether it is active, and we look up the email address on an order only when you ask us to restore that purchase on another device.
9. Your rights
You can request a copy of the data tied to your account, ask us to correct it, or ask us to delete it. Parents and guardians can do the same on behalf of a child profile linked to their account. Requests are handled by a person, not an automated system.
10. Changes to this policy
We update this policy when the product changes or when we sign on a new vendor that handles personal data. Material changes will be flagged in-app or by email so you have a chance to review them before they take effect.
