Effective date: August 4, 2026
These Terms of Use are an agreement between you and Luka Bugarin, Serbia, the operator of Zero Nic ("Zero Nic", "we", "us"). By downloading or using the app, you agree to these terms.
Zero Nic is an educational and motivational companion for people who want to stop smoking, based on an understanding-based approach to habit and nicotine dependence. It is not a medical device, does not provide medical advice, and is not a substitute for professional healthcare. Nicotine withdrawal affects people differently; if you have a medical condition, are pregnant, or take medication whose dosing is affected by smoking status, consult a doctor before and while quitting.
Zero Nic is an independent product, not affiliated with, endorsed by, or connected to any organisation.
You must be at least 16 years old to use Zero Nic. If the law where you live requires a higher age to agree to these terms or to the processing described in our Privacy Policy, that higher age applies. By using the app, you confirm that you meet the applicable age requirement.
Quitting smoking depends on you. The app provides structure, reading material, and tools; it does not and cannot guarantee that you will stop smoking or stay stopped.
Some content and features require a one-time purchase or subscription ("Premium"), processed by Apple App Store or Google Play under their terms. The price and billing period shown by the store before purchase control the transaction. Subscriptions renew automatically unless cancelled in your store account settings before the renewal date. Cancellation normally takes effect at the end of the current billing period. A lifetime purchase is a one-time, non-renewing purchase. Refunds are handled by the respective store under its policies and any rights provided by applicable law. You can restore eligible previous purchases from within the app.
Premium includes AI-generated conversations. AI output is generated automatically and may be inaccurate or inappropriate despite our safeguards. It is not medical, psychological, or professional advice. Use judgement, and in a crisis contact a professional or emergency services.
Your entries are stored on your device. You are responsible for backups (Settings → Export my data). We are not liable for data lost through device loss, uninstalls, or failed transfers.
Optional features send limited data to service providers as described in our Privacy Policy, which forms part of these terms. An exported backup is a separate file under your control.
Except where applicable law expressly permits it, don't attempt to reverse engineer or resell the app. Do not abuse the app or its AI endpoints. We may rate-limit or suspend abusive usage of server-side features.
The app draws on publicly known concepts of quitting smoking. Our original text, selection, arrangement, design, software, and branding are owned by or licensed to us. Third-party names, marks, and materials remain the property of their respective owners. We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to use the app for its intended purpose. You may not extract, copy, resell, or republish app content except where applicable law expressly permits it.
The app relies on third-party services including app stores, RevenueCat, Cloudflare, Google Gemini, and Sentry. Their availability and processing are also governed by their own terms. We may maintain, change, rate-limit, suspend, or discontinue features where reasonably necessary for security, legal, technical, or operational reasons. We do not guarantee that every feature will always be uninterrupted or error-free.
Nothing in these terms excludes or limits statutory consumer rights or liability that cannot legally be excluded or limited, including liability for fraud, wilful misconduct, or death or personal injury caused by negligence where applicable. Subject to those mandatory rights, the app is provided "as is" and, to the maximum extent permitted by law, our total liability is limited to the amount you paid for Premium in the twelve months preceding the event giving rise to the claim.
These terms are governed by the laws of Serbia. If you are a consumer, this choice does not remove any mandatory protections or rights you have under the law of the country where you live, and you may bring a claim before any court that applicable consumer law permits.
We may update these terms for legal, security, technical, or service changes. The current version will remain available at this URL with an updated effective date. Material changes will be clearly communicated in the app or through another reasonable channel before they take effect where required by law. Changes do not reduce rights that have already accrued under applicable law.
