None of my plugins sends any data to external servers
The plugin Link Log stores IP-addresses of visitors in your database to identify multiple clicks from the same IP-address and exclude them from counting. As of version 3 the link-log plugin encrypts the visitors IP-address before storing it into the database. The encrypted IP-addresses can not be decrypted. The plugin also forces you to encrypt the already existing data.
