DataReins

See where your personal data goes, understand meaningful privacy changes, and take action — privately in your browser.

DataReins helps you understand and manage your online privacy relationships. As you browse, DataReins builds a private, evidence-backed map of the organisations you interact with, the types of personal information that may be involved and other companies named in public privacy disclosures. Your privacy map stays in your browser. DataReins does not store the values you type into website forms and the current beta does not use a developer-operated backend. WHAT DATAREINS HELPS YOU DO • See the organisations connected to your online interactions • Understand the types of personal information that may be involved • View other companies named in public privacy disclosures • Review meaningful privacy changes • See which relationships may need attention • Find official privacy contacts, forms and account controls • Prepare and track privacy requests while remaining in control • Correct findings and review their supporting evidence • Export or reset your locally stored privacy map PRIVACY BY DESIGN • Your privacy map is stored locally in Chrome • No DataReins account is required • No advertising or sale of personal information • No analytics in the current beta • Passwords, uploaded files and form values are not stored • Privacy requests are never submitted automatically • Monitoring and notifications can be paused or disabled HOW IT WORKS 1. Browse normally after granting clearly explained website access. 2. DataReins recognises limited relationship signals and field metadata without retaining what you type. 3. It reviews relevant public privacy information for supporting evidence, possible additional providers and official action routes. 4. You decide whether to review, correct or act on each finding. IMPORTANT LIMITATIONS DataReins is beta software. Coverage varies between websites, and public privacy disclosures may be incomplete, outdated or ambiguous. A company appearing in a public disclosure is evidence of a possible relationship. It is not proof that the company received or currently holds your specific personal information. DataReins helps you find and organise privacy actions but does not provide legal advice, guarantee deletion or confirm that an external organisation has completed a request. Your data. Your control.
