Your storing in password protected zip file is better than storing it plain text in a file on your computer but the password encryption of zip is probably not that strong. A friend of mine insists on using a disk encrypted pen drive with an office document having his passwords. I hope he has a backup drive :)
On the Fediverse with micro-blogging like Mastodon, Pleroma and similar there is a hashtag which is related to work. I forgot what the exact hashtag is but I saw other people recommending it whenever people ask for job opportunities. If you get a match you may be able to contact them directly via email. Good luck!
What’s your level of trust in their provider, netcup? For instance I would never trust anything hosted at Hetzner and Linode because they’ve been known to intercept traffic.
Interesting. Do you have sources for this statement ?
Agreed. Trust is always a thing on the Internet. And uptime too. searx.be / yewtu.be (From the same person. They posted when their previous provider took them down) has been stable and useful for me for a long time. I do trust Disroot and they have search too : search.disroot.org If it does not work you can complain via their XMPP chat, or file a bug at one of their other services.
