Frequently asked questions
Are these tools really free?
Yes. All four calculators are completely free, with no sign-up, no email capture, and no paywall. Results are calculated in your browser and never sent to a server.
Is my data private?
Completely. All calculations happen locally in your browser. We don't collect, store, or transmit any of the information you enter. There are no accounts and no tracking cookies.
How accurate is the T-Break Duration Calculator?
The recommendations are based on published research on CB1 receptor recovery timescales, adjusted for usage frequency, consumption method, and individual goals. It gives a personalised range — not a one-size-fits-all number.
What's the difference between the tools and the app?
The tools give you a one-time snapshot: your spending, your ideal T-break length, your withdrawal timeline. The app tracks your progress over time — daily check-ins, craving patterns, mood trends, money saved, and personalised insights that emerge after a week of logging.
Can I use these tools on my phone?
Yes. All tools are fully responsive and work on any device with a web browser — iPhone, Android, tablet, or desktop. No app download needed.
