By downloading or using 336 ("the App"), you agree to these Terms of Use. If you do not agree, do not use the App.
The App provides general information about nicotine withdrawal based on published clinical research. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider before making decisions about your health. If you experience severe withdrawal symptoms, seek medical attention immediately.
The App is intended for personal, non-commercial use by individuals who wish to quit nicotine products. You agree not to misuse the App, reverse engineer it, or use it for any unlawful purpose.
The App is provided "as is" without warranties of any kind, express or implied. We do not guarantee that the App will be error-free, uninterrupted, or that it will achieve any particular health outcome. Quitting nicotine is a personal journey and results vary.
To the maximum extent permitted by law, the developers and publishers of 336 shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the App.
Your use of the App is also governed by our Privacy Policy. Your data is stored locally on your device and you are responsible for its security.
The App is free. Donations are voluntary and non-refundable. Donations do not grant any additional features, rights, or privileges.
We may update these Terms at any time. Continued use of the App after changes constitutes acceptance of the revised Terms.
