Looking for beta testers & honest feedback on a privacy-first fertility awareness app

Hi everyone,

I'm looking for a few people to test an early version of a project I've been building and give honest feedback.

It's called canihavesex.today—a privacy-first fertility awareness app that helps users understand whether they're likely to be fertile today using the symptothermal method. It's open source, doesn't require an account, and is designed to keep personal data on the user's device.

I'm mainly looking for feedback on:

• Whether the landing page clearly explains what the app does
• Whether you'd trust the product after seeing the homepage
• Whether the demo is intuitive and easy to navigate
• Anything that feels confusing, missing, or unnecessary
• Bugs, UX issues, or rough edges you notice

Landing page: https://canihavesex.today

I'm not looking for compliments—I'd much rather hear what would make you close the page or decide not to use it.

Thanks in advance to anyone willing to take a look!
