FORTRESS21 – COOKIE POLICY

Last Updated: 12/19/25

1. What are Cookies?

Cookies are small text files stored on your device when you visit a website. They allow the site to remember your actions and preferences (such as your booking slot) over a period of time.

2. Our Philosophy: Essential Use Only

Unlike most websites, we do not use cookies for retargeting, marketing, or selling your data to advertisers. We operate on a strict "Need-to-know" basis. We use cookies and similar technologies (like local storage) solely for:

  1. Functionality: Making sure the website actually works.

  2. Security: Detecting bot attacks and preventing payment fraud.

3. Types of Cookies We Use

3.1. Strictly Necessary Cookies

These are required for the operation of our website. They include:

  • Session cookies: To keep your booking session active while you select a time on Cal.com.

  • Payment cookies (BTCPay): To monitor the status of your Digital asset invoice (e.g., detecting when a technical procedure is confirmed on the network protocol) without refreshing the page.

3.2. Security  & Fraud Prevention (Third-Party)

If you choose to pay via credit card, our processor Stripe places cookies and utilizes browser fingerprinting technologies.

  • Purpose: These are not for advertising. They are used to detect abnormal behavior (e.g., bots testing stolen cards) and ensure the operational validation is legitimate.

  • Data collected: IP address, device ID, and browser patterns.

  • Opt-out: These cannot be disabled if you wish to use the credit card payment method, as they are essential for financial security compliance.

4. Third-Party Service Providers

We use trusted third-party tools that may set their own cookies to enable their functionality. We do not control these cookies, but we have vetted these partners for privacy alignment.

5. Managing Your Preferences

You can control or delete cookies via your browser settings (usually under "Privacy  & security").

  • For digital asset users: If you block all cookies/javascript, BTCPay Server may not auto-update the invoice status, requiring you to manually refresh the page to see your operational validation confirmation.

  • For card users: Blocking cookies may cause Stripe to reject your technical procedure due to inability to perform fraud checks.
