axl uses your ARX Studios account to sign you in, with Google or an email link. We store your account ID and email address so your short links belong to you.
For each short link you create, we store the destination URL, the short code, when it was created, its expiry date if you set one, and how many times it has been opened.
When someone opens a short link, we only increase that link's click count. We don't store anything about the visitor.
