Privacy Policy

Short form

We’ll do no harm and will never sell or give away your personal information to anyone ever (unless required to by law). And we mean, ever. We’ll do everything we can to protect your personal information. That’s a promise.

We have opt-in policies and won’t bug you or annoy you with requests or email. We may occasionally ask your opinions via a questionnaire on login which you are free to opt-out of.

Please be nice and accept that by signing up that we need to collect some data from your use of the site to make the site work for you and us and to conduct research into how people learn. No personally identifiable information including your email address will ever be given to anyone outside Ever.

We may have adverts in the future so we can generate revenue to pay for the upkeep of the site (it costs LOTS to build and maintain for you. Don’t ask how much, you’ll faint).

The long form below supersedes that above.
