+**Storage quota and detection tradeoff:** By default, the binary normalizes storage quota to pass FingerprintJS, which blocks persistent contexts that report non-incognito quota values. This means detection services that penalize incognito mode (like BrowserScan's `notPrivate` check, -10 points) will still flag it. If your target site penalizes incognito but doesn't use FingerprintJS, set a higher quota to appear as a regular profile:

 ### Site detects incognito / private browsing mode
 
-By default, `launch()` opens an incognito context. Some sites (like BrowserScan) detect this. Use `launch_persistent_context()` instead — it runs with a real user profile, so incognito detection passes:
+By default, `launch()` opens an incognito context. Some sites penalize this. Use `launch_persistent_context()` to get a real profile with cookie persistence:
 
 ```python
 from cloakbrowser import launch_persistent_context
 
 ctx = launch_persistent_context("./my-profile", headless=False)
-page = ctx.new_page()
 ```
 
-```javascript
+If the site still flags incognito, raise the storage quota to appear as a regular browsing session. See the [storage quota tradeoff](#launch_persistent_context) for details on how this affects different detection services.
-import { launchPersistentContext } from 'cloakbrowser';
-
-const ctx = await launchPersistentContext({
-  userDataDir: './my-profile',
-  headless: false,
-});
-```
-
-This also gives you cookie and localStorage persistence across sessions.
