ZenHome is a set of private web services for its members and invited guests. This policy covers the "Sign in with Google" step in front of them.
When you sign in, Google tells us your account's email address and that Google has verified it. We request no other information and no access to your Google data (mail, contacts, files or anything else).
Your email address is compared with a short list of accounts that may enter. If it is on the list, your browser receives a session cookie, valid for up to seven days, so that you do not have to sign in on every visit. If it is not, you are turned away.
The web server's logs record each request (time, address, page and, after sign-in, the account) for troubleshooting and security. They stay on ZenHome's own servers and are not shared, sold or used for advertising or profiling. The service you reach after signing in may keep its own records of what you do there.
You can sign out by deleting this site's cookies, and you can withdraw the access at any time in your Google account under Security → Third-party apps and services. To ask about or remove anything we hold about you, contact the person who invited you.
