None of my plugins sets cookies
Except of Link Log none of my plugins collects or stores any data (details see below)
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.
Usage of cookies in WordPress Admin
Some of my plugins set a cookie named
[plugin]_current_tab. This cookie is only set if you visit the plugins settings page in WP admin. It doesn’t affect visitors of your website. The only purpose of this cookie is to store, which tab is currently opened. If you go to another page in WP admin and come back, the same tab will be activated automatically. The cookie only stores the active tab, no other data. No data is collected and nothing is shared with external services. The cookie is deleted as soon as the browser is closed.
