This Policy explains how the Jogen app and related website handle your data. See the AI Data Processing Statement for AI data flows and consent.
1. Scope
This Policy covers accounts, language choices, text and voice practice, learning history, point purchases, support, and the website. Third party sign-in, stores, AI, and device speech services have their own policies.
2. Data we collect
We may handle account identifiers, email, and display name from Google or Apple; interface and learning languages, characters, scenarios, messages, AI replies, study notes, and conversation history; point balances, store product and transaction identifiers, verification and refund status; and app version, device and network technical information, errors, and security logs. Voice use may involve microphone permission, recognized text, and reply text used for speech synthesis. Onboarding does not ask for birth date, contacts, or precise GPS location. Older versions may have left birth-date data on the device.
3. Purposes
We use data for authentication, personalized practice and chat, learning continuity, point and refund verification, fraud prevention, troubleshooting, support, and legal obligations. We do not publicly market private conversations merely because you use Jogen.
4. AI and speech
After you consent to AI chat, Jogen sends the current message, some history, and the learning context through its server to OpenAI or Google Gemini to generate a reply. Gemini speech synthesis receives the reply text only after separate consent; declining speech consent does not affect text chat. If Live calling is enabled, after AI consent and microphone permission, call audio is sent to OpenAI over WebRTC for real-time replies and transcripts; transcripts may enter the signed-in account's conversation history. Short speech input primarily uses the device's recognition capability, subject to device and system settings. Do not submit sensitive data you do not want third parties to process. Providers may handle or retain data under their applicable terms. We do not make a blanket guarantee of no retention or model improvement.
5. Recipients
As necessary, Supabase processes authentication, database, and function requests; OpenAI or Google Gemini processes AI requests; Apple App Store or Google Play processes purchases; and the device system may provide speech recognition or playback. We share data only as needed for the feature, support, safety, or law. We do not sell private conversations. Each provider's practices depend on its applicable policy and service plan.
6. International transfers
Cloud and AI services may process data outside your country. The provider's current infrastructure determines processing locations and subprocessors. Transmission uses protections such as HTTPS/TLS, but no internet transmission is risk free.
7. Storage and retention
Signed-in conversation and account data are stored in Supabase; the device may also retain chat caches, settings, and guest data. We usually retain data until you delete it or your account, or it is no longer needed for the service. Necessary transaction audit, duplicate-purchase prevention, refunds, disputes, security records, and backups may be kept for lawful or legitimate periods. Provider retention is governed by provider policies.
8. Security
We use transport encryption, authentication, access controls, and other appropriate measures. This is not end-to-end encryption or a promise of absolute security. Report suspected account misuse promptly.
9. Aggregated data
We may use aggregated or de-identified information to assess quality and operation without re-identifying you. This does not authorize public display or sale of private conversations.
10. Your rights
Depending on applicable law, you may request access, a copy, correction, deletion, or a stop to collection or use. You can withdraw AI chat consent in settings; the related AI function may then be unavailable. Withdrawal does not undo processing already lawfully completed. Contact us in settings or at waynemvrs@gmail.com. We may verify identity to protect your account.
11. Account and guest deletion
Signed-in users can request deletion of Jogen account data in settings. Guests can clear local guest data there. Jogen deletion addresses chat, study notes, Live records, settings, and unused points. Necessary store transaction audit data may be retained after account unlinking. Shared sign-in identity and data from other apps are outside this process. Apple and Google handle their own transaction records.
12. Minors
Users under 18 need parent or guardian consent for use and related data handling. Onboarding does not ask for birth date. If we learn of data that should not legally be processed, we will handle it under applicable law.
13. Website and device data
The website and app may use necessary local storage, language preferences, and technical logs. Browsers, operating systems, and stores may collect data under their own policies. Your website language preference is stored in the browser and can be cleared there.
14. Policy changes
We show the latest update date here and will reasonably notify you through the app or website of material changes. We will obtain fresh consent first where the law requires it.
15. Contact and complaints
Email waynemvrs@gmail.com with the data you wish to access, change, or delete, or with your concern. We will respond after verifying identity and applicable legal requirements. You may also complain to a competent data protection authority.
16. Governing law
Subject to mandatory privacy and consumer protections where you live, this Policy is interpreted under Taiwan law. This clause does not limit your statutory data rights.
