Xdquant ("we", "us") respects your privacy. This policy explains what information we collect when you use the Xdquant app (the "App"), how we use and protect it, and your rights.
1. Information We Collect
- Account information: the email address and password you use to sign up and sign in, plus the nickname and avatar you choose to set.
- Exchange API credentials: the exchange API Key and Secret you choose to add. They are uploaded to our servers so we can retrieve your account balances and perform actions you initiate in the App.
- Preferences: watchlists, price alerts and language settings, used to sync your settings across devices.
- Subscription status: when you buy Xdquant Pro through Apple, we receive your subscription status and expiry date. Payments are processed by Apple; we never receive your card or payment details.
The App does not use any third-party analytics, advertising or crash-reporting SDKs. We do not track you across other apps or websites, and we do not collect your contacts, photos (other than an avatar you upload) or precise location.
2. How We Use Information
- To create and maintain your account and verify your identity;
- To read your exchange account data and perform the actions you initiate through the API you authorize;
- To provide market data, price alerts, AI analysis, backtesting and other features;
- To manage your subscription benefits;
- To respond to your inquiries and send necessary account security notices.
We do not sell your personal information or use it for advertising.
3. API Key Security
- API Keys and Secrets are transmitted over encrypted connections (HTTPS), stored encrypted on our servers, and used only to provide the service to you.
- We strongly recommend that you disable withdrawal permissions when creating an API key and enable an IP whitelist where possible.
- You can remove an API key in the App at any time, or revoke it directly on the exchange.
AI Analysis
AI analysis in the App is provided by DeepSeek and is requested by our servers. Only public market data (such as candlesticks, prices and volume) is sent to DeepSeek. No personal information, including your email, account details, API keys, balances or positions, is sent.
4. Sharing
We share your information only:
- With the relevant exchange, via your API, when you instruct us to;
- With service providers required to provide the service (e.g. cloud hosting, and DeepSeek for AI analysis), which are bound by confidentiality obligations; the AI provider receives only public market data;
- When required by law or by a lawful request from a court or government authority.
5. Retention and Deletion
We keep the information above while your account is active. You can delete your account in the App or email us to request deletion. After deletion, we remove your account and API information within 30 days, unless the law requires us to keep it.
6. Your Rights
You may access, correct, export or delete your personal information, or withdraw your consent. To exercise these rights, contact us at the email below. We will reply within 15 business days.
