This policy explains what information Mathemission collects when you use mathemission.in (the website and store) and Mathemission Study (the practice app at study.mathemission.in, including the version installed from an app store), why we collect it, and what you can do about it. Mathemission is run by Ashutosh Kumar (AK). Questions about this policy: mathactiveonly@gmail.com.
1. What we collect
In the Mathemission Study app
- No account needed to practise. You can use the app without signing in. Your progress is then kept only on your own device.
- If you sign in: your email address. Sign-in works with a one-time email link; we never ask for or store a password.
- Your study data, so it is saved across your devices: tests you attempt, your answers and scores, your mistake notebook, the notes you write, and app settings.
- Ask AK messages: the text, and any image you choose to attach, when you send AK a question, plus AK’s reply.
- Video plays: when you play a short explanation clip, we record that it was played, to learn which explanations help.
On mathemission.in (website and store)
- When you buy an e-book or course: your name, email address and phone number, and the order details.
- Payments are handled by Razorpay (UPI, cards, net banking). Your card, UPI or bank details go to Razorpay, not to us.
- Contact and other forms: whatever you type in them.
- Website statistics: the website uses Google Analytics to count visits and see which pages are read. It uses cookies and collects data such as pages viewed, device type and approximate location.
2. How we use it
- To run the app: sign you in, save and sync your progress, and show your notes and mistakes on every device you use.
- To unlock what you bought: the app matches the email you sign in with to the email on your store order, and opens the matching RA Plus assignments.
- To deliver your purchases and send order emails.
- To answer your Ask AK questions.
- To improve the questions, solutions and website.
We do not sell your information, we do not show advertising in the app, and we do not use your study data for advertising.
3. Who else handles it
We use these services to run Mathemission. Each one processes data only to provide its service to us:
- Supabase: the app’s database and sign-in.
- Hostinger: hosting for the website, store and app.
- Razorpay: payments.
- Google Analytics: website statistics.
We may also share information if the law requires it.
4. How long we keep it
We keep your account and study data for as long as you use the app. Order records are kept as long as required for accounts and tax. If you ask us to delete your data, we will do so, except for records we must keep by law.
5. Your choices
- Use the app without signing in; nothing is sent to us apart from loading the questions.
- Delete your own notes and Ask AK messages inside the app.
- Email mathactiveonly@gmail.com to see, correct or delete your data, or to close your account. Please write from the email you signed in with.
- Block or clear cookies in your browser settings.
6. Students under 18
Many of our users are school students. If you are under 18, please use Mathemission with the knowledge of a parent or guardian, and ask them to make any purchase. A parent or guardian can email us to see or delete a student’s data.
7. Security
All connections use HTTPS. Each student’s study data, notes and messages are protected so that only that student (and AK, to answer questions) can read them. No system is perfectly secure, but we take reasonable care to protect your information.
8. Changes
If we change this policy, we will update the date at the top of this page.
