Hey Product Hunt!

I'm the developer behind CycleSync and I'm really excited to share it here today.

I built CycleSync after getting frustrated with cycle tracking apps that are bloated, require accounts, and quietly sell your health data. I wanted something that just lives in your browser, works instantly, and keeps everything private.

A few things I'm proud of:

• Onboarding flow (with cycle length + period length steps)

• Period countdown bar

• Period started button

• Symptom date defaults to today

• Uninstall feedback form (moved to background.js) which works

• manifest.json warning fixed
  Out of all the extensions really enjoying this one.

Further layout and rendering improvements for Windows users, thanks for your support.

36 downloads and the Users tab gives us much more useful data than before. A few things really stand out:

Windows is now 64% of your active users. That completely flips the picture from before. It means the Windows CSS fix in 1.0.1 is genuinely urgent over half your current user base is on a potentially broken experience.

India at 12% is a surprise. That's organic discovery you weren't targeting, which suggests there's real demand there.

The "Other" region at 56% is huge. Your audience is far more international than the US/UK/Australia breakdown suggests. This also means the Spanish-language uninstalls we saw earlier are likely part of a broader non-English user base that's not being served well.
