Sometime you want to log your own visits, especially when your blog or website is still small and your navigation can really influence the stats present in Metrical.
For this reason, you can filter IPS inside an application: just go to the application settings and you can add a list of IPs. Metrical won't save visits from these IPs.
If you want, you can also use a wildcard to filter IPs. Example: if you put only '1.2.' instead of a complete IP, Metrical will filter out all IPs that starts with that address (188.8.131.52, 184.108.40.206, 220.127.116.11, ecc)
This comparison between the visitor IP and the list of IPs inside your application is done as the first thing during a visit, so no data will be saved of that visit if the IP matches.
