What this notice covers
The Unlearn Math app for iPhone and iPad, this website (unlearnmath.app), the website chat and email to us.
What we collect
In short: from the app, nothing. From the website, only what you send us and standard server logs.
| Source | Data |
|---|---|
| The app | Nothing reaches us. Your skills, scores, XP, streak, reminder times and settings are stored on your device only. |
| App purchases | Apple processes the payment. We never see your card or Apple Account details. Apple tells the app only whether Premium is active. |
| Website visits | Server and network logs: IP address, browser type, the page requested, the time, and the page you came from. |
| Website chat | Your name and email address (asked before a chat starts), your phone number if you choose to give it, your messages and any files you send, the page you were on, basic browser details (browser type, language, time zone), and your rating if you answer the optional survey at the end. |
| Your email address, name if given, your message and any attachments. |
Why we use it and our lawful basis
| Purpose | Lawful basis |
|---|---|
| Answering your chat or email | Legitimate interests (replying to people who contact us) |
| Helping with a purchase, restore or refund question | Performance of a contract, or steps you ask for before one |
| Keeping the website secure and working (server logs) | Legitimate interests (security and fault-finding) |
| Keeping records we must keep by law | Legal obligation |
We do not use your data for marketing, profiling or advertising, and we do not sell it.
Do you have to give us data?
No. The app works without giving us anything. To chat, we need a name and email address so we can reply if you leave the page. No decisions about you are made by automated means.
Live chat
In short: if you start a chat, we keep what you tell us so we can reply. The chat runs on our own server.
The chat uses Chatwoot, a self-hosted chat tool. It loads only when you click the Chat button. Opening it sets one cookie, cw_conversation, which keeps your conversation open when you reload or come back. Before a chat starts we ask for your name and email address; a phone number is optional. If you leave the page, we can carry on the conversation by email. When a chat ends we may ask you to rate it; answering is optional. The data stays on our own server and is not shared with anyone.
Cookies and device storage
In short: one cookie, set only if you open the chat. No analytics or advertising cookies.
| Name | Purpose | Lifetime | Why no consent is needed |
|---|---|---|---|
cw_conversation | Keeps your chat conversation open between pages and visits | 12 months | Strictly necessary for the chat you chose to open |
You can delete it at any time in your browser settings. The chat will then start a new conversation.
Who sees your data
In short: a small set of providers process website data for us under written terms. Apple handles payments as a separate controller.

|---|---|---|

If a request is complex we may take up to two more months, and we tell you within the first month. We do not charge a fee unless a request is clearly unfounded or excessive.
