Quit21 provides educational and behavioral support for smoking cessation. It is not a medical device and does not diagnose, treat, cure, or prevent any disease or medical condition.
Health and recovery-timeline information in the app reflects publicly available guidance from sources such as the CDC and WHO, describing general patterns observed across populations. It is not a personal medical measurement, and results vary between individuals. Quit21 never claims that any specific benefit is guaranteed, that a health condition has been resolved, or that a person's medical risk has been eliminated.
Where Quit21 mentions medication sometimes used in smoking cessation (for example, nicotine replacement therapy, varenicline, or bupropion), this information is educational only. Quit21 does not prescribe medication, does not recommend a specific medication for you, and does not calculate a personal dosage. Always speak with a doctor or pharmacist before starting, stopping, or changing any medication.
Quit21 is not an emergency medical service and cannot manage a medical emergency, severe withdrawal symptoms, or a mental health crisis. If you believe you are experiencing an emergency, contact your local emergency number or an appropriate crisis or medical service immediately.
