Support
It's free, and it's staying that way.
CPAP Clarity has no paywall, no account, and no ads on the pages that matter. If it has helped you make sense of your own sleep data, there are two easy ways to say thanks. Both are completely optional.
No paywall
Every feature is free for everyone.
No account
Nothing to sign up for. Just open it and go.
Private by design
Your data is read in your browser, never on a server.
Two ways to help
Both run through Buy Me a Coffee. Pick whichever fits, or neither. The site works exactly the same either way.
Buy me a coffee
A one-time thank you, whenever the mood strikes. No account, no recurring charge, nothing to cancel later.
Buy me a coffeeMonthly supporter
Pitch in a little each month if CPAP Clarity has earned a spot in your routine. Cancel anytime, no questions asked.
Become a monthly supporterWhy it's free
I built CPAP Clarity because the tools I needed as a CPAP user were either too basic or locked behind a subscription. I wanted the opposite: detailed, private, and open to everyone, with no paywall and no account. That is the whole point, and it is staying that way.
Support is not a fee, and nothing on the site is gated behind it. Every feature works the same whether you give a dollar or not. A coffee or a monthly tip is simply a thank you from people who found the site useful, and a quiet signal that it is worth continuing. If CPAP Clarity has helped you understand your own data, that is already the best outcome.
Your privacy does not depend on any of this.
Your CPAP, oximeter, and wearable data is read and analyzed entirely in your browser. It never touches a server, with or without your support. Read more in our privacy commitment or learn how the site is built on the about page.
