This Cookie Policy explains how Syntropi ("we," "us," or "our") uses cookies, local storage, and similar tracking technologies when you visit or use our web application and AI-powered cognitive operating system (the "Service").
By using our Service, you acknowledge the use of these technologies as described in this policy.
1. What Are Cookies and Local Storage?
Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work securely and efficiently.
Local Storage / Session Storage (Web Storage) are standard browser technologies that allow web applications to store data locally on your device. Given the heavy client-side architecture of our "Infinite Canvas," we primarily rely on Local Storage to ensure a seamless, ultra-fast experience without unnecessary server requests.
2. How We Use These Technologies
We are building a tool for deep thinkers, not an advertising platform. We DO NOT use any third-party marketing, retargeting, or advertising cookies. We only use technologies that are strictly necessary or strictly functional for the Service:
Strictly Necessary (Essential): These are required for the operation of our Service. They include secure authentication tokens (to keep you logged in) and security protocols to prevent malicious activity. Without these, the Service cannot function.
Functional & State Persistence: We use local storage (specifically via zustand-persist and similar state management frameworks) to remember your workspace configurations. This includes:
Your UI language preferences (locale).
Custom slider values in your Command Center, such as your selected "Socratic Depth" and "Jargon Filter" thresholds.
Physics engine tweaks (e.g., canvas damping and lasso sensitivity).
Note: Because these are essential for delivering the tailored experience you requested, they are automatically enabled.
3. Third-Party Technologies
While we do not run ads, we integrate with secure third-party platforms to provide critical functionality. These providers may set their own cookies:
Google OAuth: If you choose to register or log in using your Google account, Google uses cookies to authenticate your identity securely. Please refer to Google's Privacy and Terms for more information.
Lemon Squeezy (Merchant of Record): When you upgrade to our PRO membership, our reseller, Lemon Squeezy, processes the payment. Lemon Squeezy may set strictly necessary security and fraud-prevention cookies during the checkout process to ensure a safe transaction and comply with global tax laws. Please refer to Lemon Squeezy's Cookie Policy.
4. How to Manage Your Cookies
Most web browsers allow you to control cookies and local storage through their settings. You can usually find these settings in the "Options" or "Preferences" menu of your browser.
You can choose to block or delete all cookies and local storage data.
Warning: If you clear your browser's local storage or block essential cookies, you will be logged out of the Service, and your unsaved client-side UI preferences (like canvas physics tweaks) will be reset to default.
5. Changes to This Policy
We may update this Cookie Policy periodically to reflect changes in our technology or legal requirements. We will notify you of any significant changes by updating the "Effective Date" at the top of this page.
