We're a private beta. Full terms of use will be published when we open to a wider audience. In the meantime, here's what you can rely on.
Our Privacy Policy sets out what we do with your data and the rights you have under UK GDPR. That document is binding from the date it was published.
While full terms of use are being drafted, your use of the GreenStar browser extension and website is on a private-beta, best-effort basis. The product is provided as-is during this period. We may change, pause, or end features at short notice as we iterate towards a full release.
Sustainability scores are estimates based on publicly available information, not formal audits or compliance certifications. We say so on the product itself, and we explain how scores are calculated on the methodology page.
If something on the site or in the extension is unclear or wrong, please tell us — we'd rather hear about it directly than have you wonder.
