Any simple pregnancy apps that don’t sell my data?

[Caipulli]

Hi
As the title suggests, I’m looking for a simple pregnancy tracking app that doesn’t require me to give loads of personal information when signing up and won’t sell my data to private advertisers!
I really just want to know what week + day of pregnancy I’m at on a daily basis. No shopping suggestions, yoga tips or notifications...
Any suggestions?
Thanks

Thanks I will look up that one!
I also just did another internet search and read about Expecting. Haven’t downloaded it yet (going to now) but this is what the website says:

Expecting.app was developed by three leading European parents’ organisations and financed through an Erasmus+ project financed by the European Commission, and all the content available is free. The app is fully independent and non-commercial – your data is safe and your app experience will never be interrupted with ads.

I just get the MN emails. That tells me what week I'm on and I don't get bothered by annoying patronising or very American apps.

If I need to know the exact gestation for done reason I Google for a calculator.
