Unlock Sign is designed for use by adults — parents, carers, educators, family members, and support workers — who are building signing communities around people they care about.

The app is not directed at children and we do not knowingly collect personal information from children under the age of 13. If we become aware that a child under 13 has provided personal information without appropriate parental consent, we will take steps to delete that information.

Cookies & tracking.

The web version of Unlock Sign uses browser storage (localStorage) to maintain your session between visits. We do not use advertising cookies or third-party tracking pixels.

We may collect basic, aggregated analytics (such as page view counts) to understand how the app is used. This data is de-identified and not linked to individual users.

11

Changes to this policy.

We may update this Privacy Policy from time to time. When we do, we will update the date at the top of this page. If changes are significant, we will notify users within the app or by email (if you have provided one).
