There’s actually pretty many to choose from.

Ones I’ve tried:

• https://www.ecosia.org/ (🇩🇪) I’ve found this to work best for me

• https://www.qwant.com/ (🇫🇷) also good, but I find the ads sometimes too distracting

• https://www.startpage.com/ (🇳🇱) also good

others:

• https://www.mojeek.com/ (🇬🇧) if you like the brits… but really, who does?! 😅
• https://good-search.org/ (🇩🇪) interesting
• https://swisscows.com/ (🇨🇭) lol

Honestly, just switch your default search engine in your phone-settings and see what happens. After a while you don’t even realize you’re not using Google anymore. And if you’re not pleased with the search result (which I rarely am these days, using ecosia) see if Google gives a better answer. Mostly not. Happy experimenting! ;)

Agreeing with @sachamoto. One Calendar might be what you’re looking for. it’s cross platform, you can link all your calendars, has a free tier and like a one time purchase for 5 bucks to unlock all features. And they appear to be a small dutch company. one calendar

Ah yes, ze americans are at it again… 😩
