Privacy Policy

1. Who we are

Calculated Trading ({{Legal entity name}}) is the data controller for this website and its services. Our registered address is {{Street, postal code, city, Netherlands}}. You can contact us at all times at info@calculatedtrading.com.

2. What data we collect and why

We process the following personal data. The list reflects what our product actually stores today; we never collect data we do not need.

Data Purpose Lawful basis Retention
Email address Account login, activation, password reset, order notifications Contract / consent While your account exists
Password (hashed) Secure authentication Contract While your account exists
Exchange API keys (encrypted) Placing and managing your orders through the premium dashboard Contract Until you delete them
Stripe customer & subscription identifiers Managing your premium subscription Contract While needed for billing
Analytics identifiers (cookie-less hashes) Aggregated visitor analytics Legitimate interest See section 6

Card details are processed exclusively by our payment provider Stripe and are never stored on or transmitted to our servers.

3. Exchange API keys

Your exchange API keys are encrypted at rest using AES-256 with a key held only by our backend. They are never displayed back to you and are decrypted only in memory when needed to sign a request. The platform requests read and trading permissions only and can never move funds off your exchange account. We recommend disabling withdrawal permissions on the exchange side as a best practice.

4. Cookies and local storage

We set a single strictly necessary cookie and use local storage required for the application to function. We do not use advertising, social or third-party tracking cookies (see our Cookie Policy for full details).

  • Session cookie (PHPSESSID): keeps you logged in and protects forms from cross-site request forgery.
  • Local storage: stores a short-lived connection token used by the live trading data stream.
  • Analytics: cookie-less. We store only hashes derived from your IP address and browser so we can count unique visitors without retaining personal data.

5. Who we share data with

We share data only with the processors required to deliver the service: Stripe (payment processing, refunds and subscription management) and the exchanges you connect (to place and manage orders on your behalf). We never sell your personal data. Stripe may transfer data to the United States under the European Commission's standard contractual clauses, which provide an equivalent level of protection to the GDPR.

6. Retention and deletion

Account data is kept for as long as your account exists. Analytics hashes are stored in aggregated form and are not used to identify individual visitors. You can request deletion of your account and its data at any time by contacting us, and we will remove or anonymise whatever we hold, except where we are legally required or justified to keep records (for example for billing and tax purposes).

7. Your rights

Depending on your jurisdiction (in particular the GDPR and CCPA), you may have the right to:

  • access the personal data we hold about you;
  • correct or update it;
  • request deletion ("right to be forgotten");
  • restrict or object to processing;
  • receive your data in a portable format;
  • withdraw any consent you have given at any time.

To exercise any of these rights, email info@calculatedtrading.com. You also have the right to lodge a complaint with your national supervisory authority (in the Netherlands, the Autoriteit Persoonsgegevens). Email-only reminder: no financial or personal information is ever sent unencrypted.

8. Security

We encrypt API keys at rest, hash passwords, serve the site exclusively over HTTPS, and set hardened session cookie flags (Secure, HttpOnly, SameSite). These measures are designed to protect your personal data against unauthorised access, alteration or loss.

9. Changes to this policy

We may update this policy from time to time. The current version is dated {{Date of last update, e.g. 20 August 2026}} and any changes will be posted on this page.
