This Privacy Policy explains how CutPuff ("CutPuff", "we", "us", or "our") collects, uses, shares, and protects your information when you use the CutPuff: Quit Vaping mobile application (the "App") and the website at cutpuff.com (the "Site"). The App and the Site together are the "Service".
CutPuff is operated by Ethan Khoce, an independent developer based in Singapore, who acts as the data controller for the personal data described in this policy. If you have any questions about this policy or how your data is handled, you can reach us through the contact form at https://cutpuff.com/contact.
By using the Service, you confirm that you have read and understood this policy. If you do not agree with it, please do not use the Service.
CutPuff is intended for adults aged 18 and over. The Service is not directed to children, and we do not knowingly collect personal data from anyone under 18. See Section 12 for more detail.
We collect the following categories of information.
A note on minimisation: several values you see in the App, such as your streak, money saved, and progress, are calculated on your device when needed and are not stored by us as separate records.
We use your information to:
If you are in the European Economic Area or the United Kingdom, we rely on the following legal bases under the GDPR and UK GDPR:
Where we rely on consent, you can withdraw it at any time without affecting processing carried out before withdrawal.
We do not sell your personal data. We share information only as described below.
Service providers (sub-processors). We use trusted providers that process data on our behalf so we can run the Service:
Each provider is permitted to use your data only to deliver services to us under their own data protection terms.
Legal and safety. We may disclose information if required by law, regulation, legal process, or an enforceable governmental request, or where necessary to protect the rights, safety, or property of our users, the public, or us.
Business transfers. If the Service or its assets are transferred to another party (for example, in a sale), your information may be transferred as part of that transaction. We will notify you of any such change and any choices you may have.
We are based in Singapore, and our service providers may store and process your data in the United States and other countries. These countries may have data protection laws that differ from those where you live. Where required, we rely on appropriate safeguards for international transfers, such as the European Commission's Standard Contractual Clauses and, where applicable, our providers' certifications under recognised transfer frameworks. You can contact us for more information about these safeguards.
We keep your personal data for as long as your account is active or as needed to provide the Service. When you delete your account or ask us to delete your data, we remove or anonymise your personal data within a reasonable period, unless we are required to keep it to meet legal, tax, or accounting obligations, or to resolve disputes and enforce our agreements. Analytics and diagnostic data are retained for limited periods in line with our providers' standard settings, for example up to 14 months for certain analytics data.
We use technical and organisational measures to protect your data, including encryption in transit, database access rules, and restricted access to accounts and systems. No method of transmission or storage is completely secure, so we cannot guarantee absolute security, but we work to protect your information and to address any incident appropriately.
Depending on where you live, you may have some or all of the following rights:
To exercise any of these rights, contact us through https://cutpuff.com/contact. We may need to verify your identity before responding, and we will reply within the timeframes required by applicable law. You can also delete your account and associated data from within the App. If you are in the EEA or UK and believe we have not handled your data properly, you have the right to lodge a complaint with your local data protection authority.
If you are a resident of California or another US state with a comprehensive privacy law (such as Virginia, Colorado, Connecticut, or Utah), you have specific rights regarding your personal information.
Categories collected. In the past 12 months we have collected the categories described in Section 2, including identifiers, account information, commercial information (subscription and purchase records), internet and app activity, and information you choose to provide about your vaping and cravings.
Sensitive information. Information you log about your vaping and cravings may be treated as sensitive personal information. We use it only to provide the Service to you and do not use it to infer characteristics or for advertising.
No sale or sharing. We do not sell your personal information and do not share it for cross-context behavioural advertising, as those terms are defined under California law.
Your rights. Subject to applicable law, you may request to know, access, correct, or delete your personal information, and you have the right not to receive discriminatory treatment for exercising these rights. To make a request, use https://cutpuff.com/contact.
Some information you enter, such as your vaping habits and cravings, may reveal information related to your health. We process this information to provide the tracking and taper features you ask for. Where the law requires it, we rely on your consent, and you can delete this information or withdraw your consent at any time from within the App or by contacting us. CutPuff is a self-tracking and wellness tool and is not a medical device. See our Terms of Use for the full health disclaimer.
The Service is intended for adults aged 18 and over and is not directed to children. We do not knowingly collect personal data from anyone under 18. If you believe a person under 18 has provided us with personal data, please contact us and we will take steps to delete it.
The App relies on mobile software development kits and limited on-device storage rather than browser cookies. The Site at cutpuff.com may use essential cookies to function and, where you allow it, analytics cookies to understand traffic. You can control cookies through your browser settings. Where required, we ask for your consent before setting non-essential cookies.
The Service may link to third-party websites or services that we do not control, including the Apple App Store. This policy does not apply to those third parties, and we encourage you to review their privacy policies before providing them with your information.
We may update this policy from time to time. When we do, we will change the "Last updated" date above, and for significant changes we will provide a more prominent notice within the App or on the Site. Your continued use of the Service after an update means you accept the revised policy.
If you have questions, requests, or complaints about this policy or your personal data, contact us through the form at https://cutpuff.com/contact.
