Currently, sending search queries through Tor is disabled due to resource limitations.
A privacy-respecting metasearch engine written in Python, which gives you Google search results but without ads, AMP and other types of tracking.
It does not use official Google APIs, meaning on Google's side it looks like a single client (in this case, my server) is searching every query given to Whoogle. Since my host is quite small, this still makes it quite easy to deanonimize a client (you!).
My advice is to use Farside which is a service that redirects queries to public instances of privacy-respecting alternative services, basically decentralizing your search history.
Of course, you can't log in, so you can not follow accounts either. Only a search bar for now.
Because of its small feature set, I don't see any big privacy concerns with the service, but I would recommend to install LibRedirect (fork of the unmaintained Privacy Redirect), so every Twitter link redirects instead to a public Nitter instance.
liteshort is a very simple URL shortener which doesn't collect any data about the shortened URLs, for example creation date, your IP address and other personally identifiable information. I do not read the database of URLs. Keep in mind though, that I could read it at any time, so sadly you can only take my word for it.
The Ossia Music Player is a free, open source alternative to YouTube Music, it uses the Piped API to search across video streams.
The app is able to recognize songs and collect their metadata using video data and the Content ID system. Users can log in, which allows them to create playlists.
