Unlike other price comparison tools that hide how they collect and use your data, Royalty is 100% open source and transparent about our practices.
We only collect what's necessary to provide our service, and we never sell your data to third parties.
Our entire codebase is available on GitHub. You can review exactly what data we collect and how we use it.
As an open source project, we welcome contributors who want to help improve Royalty for everyone.
We believe consumers deserve to know when they're being overcharged. Online retailers often use dark patterns and dynamic pricing to maximize profits at your expense.
Many existing price comparison tools are themselves for-profit companies with hidden agendas and undisclosed partnerships with retailers.
Royalty was built to be different - a community-driven tool that puts consumers first and remains transparent about everything we do.
