Does this site cost anything? No — every tool is free, with no account and no paywall.
Where is my data? In your own browser only. The site never receives it.
Can I use this on my phone? Yes — and you can install it to your home screen like an app (PWA).
Is this medical advice? No. See the disclaimer for details.
Which languages are available? English today, with 13 more languages rolling out across every page.
Yes. Every tool runs entirely in your browser — there is no account, no paywall, and nothing to download.
On your device only. Your quit dates and streaks live in your browser's local storage. We never receive, upload, or store them.
No. The self-tests and trackers are self-help tools, not diagnosis or treatment. If you're struggling, please see a qualified professional.
Because quitting is hard enough without fighting a language barrier. Every page is fully translated, not machine-garbled.
