1. What are Cookies and Local Storage?
Cookies are small text files placed on your device by web browsers when visiting websites. Local Storage (HTML5 localStorage) is a modern web standard allowing sites to store key-value data in your browser without sending it back to servers on every HTTP request.
2. Strictly Necessary Technical Storage (Consent-Exempt)
In accordance with Article 5(3) of the ePrivacy Directive and CNIL/EDPB guidelines, strictly necessary technical storage required for user-requested interface features does not require prior consent.
| Storage Key | Mechanism | Duration | Purpose |
|---|---|---|---|
httplens-theme | localStorage | Persistent (until cleared) | Preserves your chosen display theme (light or dark mode) across page navigations. Contains no personal tracking data. |
3. Audience Measurement Cookies (Google Analytics 4)
HTTPLens uses privacy-configured Google Analytics 4 to understand which protocol guides and diagnostic tools are most helpful to developers.
| Cookie Name | Provider | Duration | Purpose |
|---|---|---|---|
_ga | Google Analytics | 2 years | Distinguishes unique browser sessions for aggregated traffic statistics. |
_ga_* | Google Analytics | 2 years | Maintains telemetry session state. |
4. Zero-Log Diagnostic Guarantee
We reiterate that none of the interactive tools (Response Explainer, CORS Simulator, Status Picker, cURL Converter, Security Analyzer, Cache Validator, Retry Calculator, API Error Inspector) write cookies or transfer your code snippets to server storage.
5. How to Manage and Disable Cookies
You can configure, block, or delete cookies at any time via your browser settings:
