Privacy

Display name

Your display name is stored on your own device as part of saved profiles. It is used to personalize your method and is not included in anonymous community contributions.

Saved profiles

Saved methods are stored in browser local storage. You can clear them using your browser storage controls.

Shared method links contain styling variables such as hair length, goal and starting diameter. They do not include your display name or local session history.

RoundBrushLab can store saved styling methods, completed-session history and outcome feedback in your browser so you can continue or refine a method later. This personal styling state stays on the device unless you explicitly choose to contribute anonymous selections to Community Data.

Saved methods, guided sessions and feedback

Community contributions

If a shared database is connected, the wizard asks for opt-in before sending anonymous selections such as hair length category, texture category, styling goal, barrel band and method. The site does not need your name for community statistics.

Analytics and advertising

The site includes Google Analytics, Google AdSense and Microsoft Clarity. RoundBrushLab sets Google Consent Mode v2 defaults before these tags and provides privacy choices that update optional storage signals. For personalized AdSense advertising in the EEA, UK and Switzerland, the production deployment must also use a Google-certified CMP integrated with the IAB TCF. The local privacy control on this site is not a substitute for that certified CMP requirement.
