Hash Cash — Privacy Policy

Last updated: 10 April 2026

This Privacy Policy describes how Roo J Solutions Ltd (“we”, “us”, “our”), a company incorporated in Hong Kong, handles information in connection with the Hash Cash application (“the App”).

Our approach

Hash Cash is designed with privacy in mind. We do not collect, store, or process your personal content or activity for profiling, advertising, or resale. We do not monitor your behaviour in the App for marketing purposes, and we do not sell your personal information.

Information we do not collect for these purposes

In line with the above, Roo J Solutions Ltd (HK) will not:

What may still be involved

Like most software, the App may rely on your device’s operating system, minimal technical data needed to run or update the App (for example crash or diagnostics information if you or your device vendor enable it), or services required by app stores. Those are governed by the relevant platform (e.g. Apple, Google) and your device settings—not by us as a general “monitoring” programme. We do not use such channels to replace this policy with broad surveillance of you.

Children

The App is not directed at children under the age where parental consent is required in your region. We do not knowingly collect personal information from children for marketing or profiling in conflict with applicable law.

Changes

We may update this policy from time to time. The “Last updated” date at the top will change when we do. Continued use of the App after changes means you accept the updated policy, unless applicable law requires a different process.
