I considered voting for them, but I didn’t.
The reason is because there are other parties with comprehensive plans for digitalisation / IT stuff PLUS lots of other plans for healthcare, economy, infrastructure, etc.
Pirate party seems like a party focused on IT stuff only, whereas I also care about other topics, such as international trains, subsidizing healthcare, improving education and lots of other things.
(I voted for Volt Nederland BTW)
If you just want to track your data for yourself, without the social media features (like Strava has), I would recommend Opentracks.
