Quant Invest System ("QIS", "we", "us", "our") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights under applicable law including the EU General Data Protection Regulation (GDPR).
Contents
1. Data We Collect
We collect the following categories of personal data:
- Purchase data: Email address, name (if provided), and order details when you buy an EA. We do not store card numbers — payment processing is handled entirely by Stripe.
- Email address: When you subscribe to our newsletter or contact us.
- Usage data: IP address, browser type, pages visited, and time on site — collected via analytics tools (anonymised where possible).
- Communications: Any messages you send us through the contact form or email.
We do not collect sensitive personal data (health, financial account numbers, government IDs).
2. How We Use Your Data
- Order fulfilment: Processing your payment, generating your download link, and sending you the EA file.
- Customer support: Responding to your questions and support requests.
- Email communication: Sending transactional emails (order confirmation, download link) and, if subscribed, newsletter emails.
- Analytics: Understanding how visitors use our site so we can improve it. Data is aggregated and not used to identify individuals.
- Legal compliance: Maintaining order records as required by EU tax and accounting law.
We do not use your data for automated profiling or decision-making that significantly affects you.
3. Data Sharing
We share data only with trusted service providers necessary to operate our business:
- Stripe — payment processing. Stripe collects and stores your card details under their own privacy policy. We receive only a payment confirmation and your email address.
- SendGrid — transactional email delivery (order confirmation, download links).
- Mailchimp — newsletter delivery, only if you have explicitly subscribed.
- AWS S3 — secure storage of EA files. Access is granted only via time-limited presigned URLs sent to your email.
- Cloudflare — CDN, DNS, and DDoS protection. Cloudflare may process request metadata.
We do not sell, rent, or trade your personal data to any third party.
4. Cookies
We use only essential and analytics cookies:
- Functional cookies: Required for the website to work correctly (e.g., session state). These cannot be disabled without breaking functionality.
- Analytics cookies: Anonymous page-view tracking (e.g., Cloudflare Web Analytics). No personally identifiable information is stored.
We do not use advertising or tracking cookies. We do not use Google Analytics. A cookie consent banner is displayed on first visit.

- Access: Request a copy of the personal data we hold about you.
- Rectification: Ask us to correct inaccurate data.
- Erasure: Ask us to delete your data ("right to be forgotten"), subject to legal retention requirements.

7. Security
We implement appropriate technical and organisational measures to protect your data:

- EA download links are presigned S3 URLs, valid for 48 hours only
- Server access restricted to SSH key authentication
No system is 100% secure. If you discover a security vulnerability, please report it responsibly to hello@quantinvest.io.
