AI Math Kit is a browser extension for number-theory open problems and AI / formalization breakthrough guides. The problem bank, guides and prompt templates ship with the extension and read offline. The extension has no first-party server and does not collect your browsing content.
1. What we process on your device
- UI language and preferences (stored in
chrome.storage.localonly) - Optional Pro unlock via ExtensionPay: a local paid/email cache may be kept so unlock works offline for a limited TTL (~15 days if paid / ~7 days if unpaid). Payment card data is processed by ExtensionPay / its processors
- Search and filtering run locally; search terms are never uploaded
2. What we do not collect
- Page content, form data, or website cookies
- Browsing history, tab titles, or tab URLs
- Analytics or advertising identifiers; the extension UI does not make tracking requests
- Your chat content: this extension has no built-in cloud AI channel; if you paste prompts into a third-party AI, that provider’s policy applies
3. Permissions
| Permission | Why |
|---|---|
storage | Language prefs and local payment-status cache |
Host permission (only extensionpay.com) | Inject ExtensionPay scripts on purchase / login pages to complete unlock |
Problem and breakthrough content is bundled offline; reading it generates no network requests.
4. Network summary
- ExtensionPay (
extensionpay.com) — only when you open purchase, login, or force-refresh payment status - No other first-party analytics / ads; content is fully offline
5. Data storage and your rights
Preferences and payment cache stay in local storage on your device — delete them by clearing extension data or uninstalling AI Math Kit. For payment data handled by ExtensionPay, exercise your rights under its policy.
