MyEcoHandprint is a community sustainability platform built and operated by Cosvaro (yourtrustedaipartner.com). Cosvaro is the controller of the personal data described here. Questions and requests: marketing@cosvaro.com.

When you create an account: your email address and, if you sign in with Google or GitHub, the name and profile picture that provider shares with us, plus the provider's account identifier. When you complete your profile: the details you choose to enter, such as your name and default ZIP code. When you use the platform: the environmental actions, baseline items and Community Solar pledges you record, and the Eco-Points calculated from them. Technical data: the date and time you last signed in.

If you make a Community Solar pledge we ask for the details a solar developer needs to assess your area: your housing status, street address, ZIP code, utility provider and approximate monthly electricity use (kWh). A phone number is optional, and you can leave it blank. We do not ask for your utility account number. These contact and location details are stored separately from the rest of your account, in a restricted table that only the pledge functions can write to and only an authorised handover process can read. Your pledge itself records only a reference to your account, never a copy of your name or email.

To create and secure your account and sign you in. To calculate and show your environmental impact and Eco-Points. To pool Community Solar demand by utility region, in aggregate. To show you on the public leaderboard, only if you switch on "Public Leaderboard Profile". To send you Community Solar alerts or a weekly impact summary, only if you switch those on.

We process your account and activity data to provide the service you asked for (performance of a contract). We use your data for the public leaderboard, for notification emails, and for sharing a Community Solar pledge with a solar developer, only with your consent, which you can withdraw at any time in your profile.

When you make a Community Solar pledge we record which version of the consent text you agreed to, the exact wording you were shown, and the date and time you agreed. That record is kept with your pledge so that it is always clear what you were told and when. You can see your pledges, and withdraw a pledge, from your profile page.

We do not sell your personal data. Your name and impact score appear publicly only if you opt in to the leaderboard. Company rankings and all published Community Solar figures use aggregated numbers only, and pledge counts for an area are hidden when fewer than five people have pledged, so that a small area cannot reveal who took part. Our hosting and infrastructure providers process data on our behalf under contract. If you sign in with Google or GitHub, that provider tells us who you are; we do not post anything to your account.

The purpose of a Community Solar pledge is to show a solar developer that there is real demand in your area, so a project can be proposed. We have not shared any pledge with a developer yet, and this is how it will work when we do. Only the fields that developer needs for its proposal in your area are shared, and nothing more. Every handover is recorded in our audit trail: who shared it, when, which pledges, and which developer. You are told when your pledge is shared, and the handover is shown on the pledge in your account. If you would rather not take part, withdraw the pledge from your profile and it will not be included.

We keep your account while it is active. When you delete your account, we remove your profile details, your pledge contact and location details, and stop using your data; aggregated statistics that cannot identify you may be kept.

You can view and change your profile at any time, switch the leaderboard and notification options off, withdraw a Community Solar pledge, and delete your account from your profile page. You can also ask us for a copy of your data, to correct it, or to stop processing it, by emailing marketing@cosvaro.com. If you are in the EU or UK you may complain to your local data protection authority.

We use one essential cookie per portal to keep you signed in. It contains your email address and expires after 12 hours. We do not use advertising or tracking cookies.

If we change this notice we will update the version above and ask you to accept the new version the next time you sign in.
