When do we share personal data?

We don't currently share data with other organisations. If we did, it would be to help our goal of planting 1,000,000,000,000 trees.

Sometimes we explicitly ask if you would be willing to release all your personal data publicly under a CC Zero license so that your answers can help other people working in this field. Where you've agreed to this, we will publish your data so that it can have the benefit you intended.

Where do we store and process personal data?

Data is stored and processed on a platform called Heroku which iteself relies on a service called AWS. Where possible we store data on servers running in the EU, but occasionally we may store data on other servers too.

We always make sure your data is held in databases protected by long passwords and by companies which provide an appropriate level of data privacy protection.

How long do we keep your personal data for?

We keep your name, email and comments for as long as the page you commented on exists so that people can read your comments and we so that we can delete your comments specifically if you request us to.

We keep your email and password for as long as your account is active to allow you to access the site.

We keep your survey responses until we decide the responses are no longer useful (unless you chose to make them available indefinitely under a CC zero license) so that researchers can use your answers to help plan how to plant more trees.

Once the data is no longer valuable to researchers it will be deleted from the main database.

Data backups are kept for a maximum of 6 months, so it will be removed from backups after that period too.
