Privacy Policy

Applies to the Tavi iOS and Android apps and this policy site | Version 1.0 | Effective October 4, 2026

1. Controller

Shenzhen Qingyuanzi Technology Co., Ltd. (“we,” “us”) is the controller. Contact [email protected] with the subject “Tavi Privacy Request.”

2. Data we handle

On-device data includes smoking and craving events, triggers, coping actions, reduction plans, reviews, recovery states, Tavi appearance/name/tone, journey content, preferences, and optional cost estimates. Store-provided purchase data may include product ID, transaction or purchase token, entitlement status, expiration, region, refund, or revocation. If you contact support, we receive the information you choose to send. Cloudflare processes limited web security data such as IP address, user agent, time, request path, and security signals.

The launch version does not request precise/background location, contacts, SMS, call logs, microphone, camera, advertising identifiers, installed-app inventory, biometrics, HealthKit, or Health Connect.

3. Purposes and legal bases

We process information to perform the service, honor your permission choices, secure the service under our legitimate interests, and meet legal obligations. Health-related information is sensitive. If a future feature uploads it, we will provide a separate prominent notice and obtain any explicit or separate consent required by law.

4. Sharing, sale, and advertising

We do not sell personal data, use cross-context behavioral advertising, share data with brokers, or use health data for advertising. Limited information may be handled by app stores, Cloudflare, our support-email provider, professional advisers, or authorities where legally required. Providers act under contractual restrictions.

5. Retention and security

On-device data remains until you clear it, uninstall the app, or the operating system removes it. Support messages are generally retained for no more than 24 months after closure. Accessible website security logs are generally retained for no more than 30 days unless required for incident investigation or law. We use minimization, encryption in transit, platform secure storage, access controls, redacted logs, dependency review, and deletion procedures.

6. International transfers

Core health records stay on device by default. Website and support providers may process limited data internationally. Where GDPR, UK GDPR, PIPL, or similar law applies, we use an available lawful transfer mechanism and apply minimization and safeguards.

7. Your rights

Depending on your location, you may have rights to know, access, copy, correct, delete, withdraw consent, restrict or object, obtain portability, complain, and receive non-discriminatory treatment. Use in-app export/clear controls for local data or email us for information we hold. We do not sell or share California personal information for cross-context behavioral advertising and do not use sensitive information to infer characteristics.

8. Automated rules

Plans and companion messages are generated from your entries and versioned rules. They are not used for insurance, employment, credit, diagnosis, or other legal or similarly significant decisions. You may review the basis, change future plans, or stop using the feature.

9. Changes and contact

Material changes will be communicated through the app, store listing, or this page with a revised effective date. Contact [email protected].

Terms of Service

Version 1.0 | Effective October 4, 2026

By using Tavi, you agree to these Terms and the Privacy Policy. The service is intended for adults aged 18 or older and provides self-tracking, reduction planning, craving tools, education, companion and journey content, and optional subscriptions.

Health limitation

Tavi is not a medical device or healthcare provider and does not diagnose, treat, prescribe, provide emergency response, or guarantee cessation. Seek professional advice and call local emergency services for urgent symptoms or safety concerns.

Acceptable use and IP

Do not attack, scrape, reverse engineer, bypass purchases, distribute malware, infringe rights, or use the service to make clinical or other high-risk decisions for another person. We and our licensors own the app, brand, characters, art, animation, text, audio, rules, and software. You receive a personal, limited, revocable, non-transferable license.

Availability, liability, and termination

We do not promise uninterrupted or error-free service. Offline data may be lost if you uninstall without exporting. To the extent permitted by law, we are not liable for indirect losses caused by treating education as medical advice, third-party store failures, or events outside our control. Nothing excludes non-waivable consumer rights or liability that cannot lawfully be limited. You may stop using the app and clear local data at any time; deleting data or the app does not cancel a store subscription.

Law and disputes

These Terms are governed by the laws of the People’s Republic of China, without overriding mandatory consumer rights in your country. Contact us first for good-faith resolution; unresolved disputes may be brought before a competent court at the operator’s domicile, unless local mandatory law provides otherwise.

Subscription & Auto-Renewal Terms

Tavi+ provides ongoing journey chapters, messages, postcards, long-term insights, themes, and scenes. Core planning, logging, craving and recovery tools, the first complete trip, export, and deletion remain free.

Monthly and annual plans may be offered. The localized price, taxes, period, and trial eligibility shown by Apple or Google control. Unless canceled before the end of the current period as required by the store, the subscription renews automatically. A trial converts to the displayed paid plan when it ends. Deleting the app or local data does not cancel billing.

Manage through Apple subscriptions or Google Play subscriptions. Cancellation normally preserves access through the paid period. Refunds, price changes, pending purchases, revocations, and restoration follow store rules and applicable law.

Health & Medical Disclaimer

Tavi is not a medical device and does not diagnose, treat, cure, prevent, prescribe, or provide emergency services. Plans, timers, trends, savings, health milestones, and companion feedback are estimates based on self-reported inputs and general information, not personal measurements.

Consult a physician, pharmacist, or cessation service before medication or treatment decisions, especially if pregnant, breastfeeding, under medical care, or taking other medicines. For chest pain, severe breathing difficulty, loss of consciousness, severe allergic reaction, self-harm risk, or another emergency, call local emergency or crisis services immediately.

Reduction aims toward stopping; smoking less is not risk-free. A lapse is not a moral failure. Record honestly, recover, adjust, and seek professional support where appropriate.

Data Choices, Export & Deletion

The launch version has no account and creates no cloud profile. Use “Me → Privacy & Data → Export My Data” for a readable summary and JSON, and “Clear Data on This Device” to permanently remove plans, logs, companion and journey progress, health milestones, and preferences. Uninstalling normally removes local data, subject to OS behavior. Neither clearing nor uninstalling cancels a subscription.

For support-email or purchase-verification information we actually hold, contact [email protected] with the request type, platform, and minimum verification details. Do not send passwords, full payment information, or unnecessary health records. If accounts are added later, this URL and the app will provide direct account deletion.

Permissions

Notifications are requested only after you set a reminder. Motion/activity access is requested only if you choose the 100-step coping action, with a manual alternative. Photo access uses the system picker or limited save flow only when you save/share a postcard. Network access supports purchases, restoration, content downloads, and support links; core logging and craving tools remain available offline.

The launch version does not request location, contacts, SMS, call logs, microphone, camera, advertising ID, broad file access, HealthKit, or Health Connect. Denying an optional permission does not block core functionality.

Age & Children

Tavi is designed and marketed for adults aged 18 or older. We do not knowingly collect children’s personal data or sell/share minors’ data for behavioral advertising. If we learn that server-held information was submitted by a child without valid parental authorization, we will take reasonable steps to delete it. Parents may also clear on-device data directly. Contact us with concerns.

Website & Cookie Policy

This site is hosted and protected by Cloudflare. It uses no advertising cookies, cross-site profiling, or third-party analytics. Cloudflare may use strictly necessary security cookies, local storage, IP and device signals to detect abuse, rate-limit, and maintain availability. Your language choice is stored locally in your browser.

Necessary security technology cannot be disabled through a marketing-cookie banner. We honor applicable Global Privacy Control signals; because we do not sell or share data for cross-context behavioral advertising, the signal does not change an advertising setting.

Third-Party Services & SDK List

Apple App Store/StoreKit and Google Play/Play Billing provide distribution and purchases; we receive limited transaction status, not full payment details. Cloudflare hosts and protects this site and processes security request data. Zoho Mail processes support messages you voluntarily send. The launch app contains no advertising or third-party product-analytics SDK. Each release must reconcile binaries, network domains, Apple privacy manifests, Google Data safety, and this list.
