Cookie & Anti-Tracking Policy
1. Zero Behavioral Tracking Principle
Natrium operates an ad-free, surveillance-free platform. We do not use advertising cookies, retargeting pixels, tracking beacons, device fingerprinting scripts, Google Analytics, Facebook pixels, or third-party behavioral telemetry.
2. Strictly Essential Storage Inventory
The following storage elements are strictly necessary to deliver authenticated services, protect against attacks, and maintain your UI preferences:
| Identifier | Type | Provider | Purpose | Lifespan |
|---|---|---|---|---|
| natrium_session | HTTP Cookie | Natrium | Cryptographically signed session token for authenticated portal access. | 24 Hours |
| cf_clearance | HTTP Cookie | Cloudflare | Perimeter DDoS mitigation and Turnstile challenge completion proof. | Session / 30 Min |
| natrium_device_id | HTTP Cookie | Natrium | Protects against credential stuffing and brute-force intrusion loops. | 30 Days |
3. LocalStorage vs. Cookie Isolation
We distinguish strictly between browser localStorage and network cookies. Your personal preferences and custom UI layouts reside exclusively inside client-side browser storage and are never transmitted over network HTTP request headers.
4. Managing Browser Storage & Cookie Controls
You may configure your web browser to reject cookies or clear local storage at any time. However, because our session cookies are strictly essential for cryptographic authentication, blocking them will prevent you from signing in to your mailbox.
5. Policy Updates & Privacy Contact
Any modifications to our storage practices will be reflected in this policy. For questions regarding tracking disclosures, contact [email protected].
