Cookie Policy

Last updated: September 6, 2026

When you visit cipherandcurve.com ("the Site"), Cipher & Curve ("we", "us") and trusted infrastructure providers use cookies and similar browser storage technologies (such as localStorage and sessionStorage) to deliver core site functionality, maintain your interface preferences, and protect against automated abuse. This policy explains what these technologies are, why we use them, and how you can manage them.

California Privacy & Zero-Ad Commitment

We operate a zero third-party advertising policy. We do not run third-party display ads, we do not employ cross-site tracking cookies, and we do not sell or share personal browsing data with data brokers.

1. About This Policy

This Cookie Policy supplements our Privacy Policy. Please read both documents together; in the event of any direct contradiction regarding data handling, the Privacy Policy controls.

2. What Are Cookies and Local Storage

2.1 Cookies are small text files placed on your computer or mobile device by a website to remember your session and actions.

  • 2.2 Related Technologies:
  • (a) Local Storage (localStorage / sessionStorage): Data stored locally within your browser that is not transmitted with every HTTP header, used primarily to remember interface states such as language selections;
  • (b) Form Relay & Security Tokens: Ephemeral tokens generated to prevent duplicate form submissions and protect against spam bots.

3. Categories of Storage We Use

We follow a strict principle of data minimization:

  • 3.1 Strictly Necessary Storage: Essential for basic navigation, security, and rendering:
  • Language State: Stores whether you are viewing the English or Chinese edition of our site;
  • Form State Preservation: Temporarily preserves your inputs during consultation requests to avoid data loss during network interruptions;
  • Security & Abuse Prevention: Verifies authentic human requests and blocks malicious DDoS patterns.
  • 3.2 Performance & Analytics:
  • Our own analytics are cookieless: the product analytics this site runs sets no cookie and stores no identifier in your browser, counting visits from a rotating server-side hash instead.
  • Current Status: This website does not currently deploy or load any third-party analytics, behavioral tracking, or performance measurement tools (including Google Analytics 4). Your browsing metrics are not transmitted to third-party analytics platforms.
  • Reserved Term: Should we activate Google Analytics 4 or comparable measurement tools in the future to improve website performance, we will update this policy in advance, enforce IP anonymization and strict data retention limits, provide an explicit opt-out mechanism (including the Google Analytics Opt-out Browser Add-on), and deploy a compliant Cookie consent banner.
  • 3.3 Advertising & Cross-Site Tracking: This Site uses zero advertising cookies. We do not track visitors across other websites and do not sell data to advertisers.
  • 3.4 Third-Party Integrations: Where third-party interactive embeds (such as Cal.com scheduling widgets) appear, those providers may deploy their own functional cookies in accordance with their respective privacy policies.

4. Managing and Clearing Cookies

  • 4.1 Browser Controls: All major browsers (Chrome, Safari, Edge, Firefox) permit you to inspect, block, or delete cookies and site storage at any time via your browser’s "Settings / Privacy & Security" preferences. Blocking all storage may require re-selecting your preferred language upon each visit.
  • 4.2 California Rights (CCPA / CPRA): California residents possess the right to know, delete, and opt out of the sale or sharing of personal information. We state unequivocally: Cipher & Curve does not sell or share personal information for behavioral advertising.

5. Policy Updates

We may update this Cookie Policy to reflect technical or legal modifications. Any revisions will be published here with an updated revision date.
