Current July 2026 // Browser Performance Mapping
At presstrailies.hair, we maintain a clean and lightweight environment. We do not use advertising tracking cookies or cross-platform demographic harvesting metrics. Instead, we use local browser keys to support custom tool options, and to lock down security settings.
The table below provides a full map of the local storage keys, session values, and tokens that our technical network maintains on client browser devices:
| Key Parameter Name | Functional Description | Data Residency Type | Expiration Period |
|---|---|---|---|
| cookies_accepted | Saves user acknowledgment of the local storage parameters. | Local Storage Key | Persistent until cleared manually |
| cys_cache_val | Maintains last selected Cystine ratio for mathematical calculations. | Session Storage Key | Closes with browser session |
| temp_cache_val | Maintains heat levels on calculations for structural stability equations. | Session Storage Key | Closes with browser session |
If you prefer to prevent local storage variables from executing, you can easily disable cookies and local storage items inside your browser's security panel. Disabling these options will not block access to our media articles, though it will reset our calculator settings to their default values on each page reload.
