Privacy Policy for TradeMind
Effective Date: September 5, 2026
Last Updated: September 5, 2026
This Privacy Policy explains how TradeMind: Quant Math Prep ("we," "our," or "us") handles your information when you use our mobile and desktop application on iOS and macOS, and when you use the browser practice tools at trademindapp.com. We are committed to providing a transparent, secure educational experience.
1. Website scope (trademindapp.com)
This section describes the public website as implemented on September 5, 2026. It does not make claims about infrastructure settings that are not visible from the site code or the deployed Cloudflare account.
- Browser practice: the public simulators run in your browser. They do not ask you to create a website account, and the website code does not post your answers or results to a TradeMind application server.
- Cloudflare delivery and analytics: the site is delivered through Cloudflare and includes Cloudflare Web Analytics' beacon script. Cloudflare describes that product as cookie-free. Its handling of request, analytics, and edge data is governed by Cloudflare's own terms and configuration; this policy does not state a retention period that we cannot verify from this repository.
- Email links: the Contact and Partners forms build a
mailto:draft in your email app. Nothing is sent until you send it from that app, and the form does not first submit its fields to the TradeMind website.
2. Information We Do Not Collect in the App
We believe that your interview preparation and practice data should remain private.
- No Personal Identifiable Information (PII): We do not require you to create an account, register, or provide your name, phone number, physical address, or personal email address to use the core features of the app.
- No Tracking or Advertising: We do not track you across third-party apps or websites, nor do we sell, rent, or trade your data to advertisers or data brokers. We do not integrate third-party advertising SDKs.
3. Local & iCloud Data Storage
To provide seamless functionality, our app generates and stores test results, custom difficulty settings, and practice histories.
- Local Device Storage: All cognitive game scores, high-speed mental math results, and custom settings are stored locally on your device.
- Apple iCloud Syncing: If you have enabled iCloud on your Apple devices, your practice progress may be synced across your iOS and macOS devices using Apple's native CloudKit/iCloud infrastructure. This data is encrypted by Apple and stored within your private iCloud account. We do not have direct access to, nor do we store, your synced data on any external servers.
4. In-App Purchases and Subscriptions
TradeMind offers auto-renewable subscriptions and one-time purchases (e.g., TradeMind Pro) to unlock advanced practice modules and assessment banks.
- Apple StoreKit Processing: All financial transactions, subscriptions, billing processing, and refunds are handled entirely and securely by Apple Inc. via the Apple App Store.
- Payment Privacy: We never receive, process, or store your credit card numbers, billing addresses, or Apple ID credentials. We only receive anonymous, non-identifying transaction receipts from Apple to validate whether a user has an active pro subscription or lifetime entitlement.
5. Third-Party References and Legal Disclaimer
TradeMind is an independent interview preparation tool designed to simulate high-speed mental math and sequence assessments.
- Non-Affiliation: This app is not affiliated with, endorsed by, sponsored by, or otherwise associated with Optiver, Akuna Capital, Flow Traders, Citadel, Two Sigma, Jane Street, or any other financial institutions or quantitative trading firms mentioned within the practice modules.
- Trademarks: All company names, firm names, trademarks, and logos belong to their respective owners and are used strictly for descriptive and reference purposes only.
6. Children's Privacy
Our application is designed for university students and professionals preparing for quantitative finance and engineering interviews. We do not knowingly solicit data from or market to children under the age of 13 (or the equivalent minimum age in your relevant jurisdiction).
7. Changes to This Privacy Policy
We may update our Privacy Policy from time to time to reflect changes in our app's functionality or legal requirements. Any updates will be posted on this page with a revised "Last Updated" date. Your continued use of the application after any changes signifies your acceptance of the updated terms.
