LIGHTVESSEL 中文

Privacy Policy

Effective: September 14, 2026 · Last updated: October 4, 2026

Lightvessel ("Lightvessel," "we," "us," or "our") is an AI-powered emotional companionship app operated by WANG XIAOHANG. This policy explains what information the app and this website process, why it is processed, and the choices available to you.

In short: conversation history, mood records, memories, and drift bottles are stored on your device. Message content and limited context are transmitted securely when needed to generate an AI response. We do not sell personal data or use it for advertising. The app does not include advertising or tracking SDKs.

1. Information we process

Account information. Sign in with Apple provides a unique identifier for your account. We use it to authenticate requests, enforce free-use limits, associate subscription status, and support deletion. We do not request your Apple Account password or payment-card information.

Conversations, mood information, memories, and drift bottles. These records are stored locally on your device. To produce a reply or another AI-generated feature, the app may send the text you provide, recent conversation context, locally generated relationship context, and relevant recent mood information through our server to Google Cloud's Vertex AI Gemini service. Our server does not keep a cloud copy of ordinary conversations. Requests are processed transiently, although Google may retain limited data as described by its Google Cloud data-processing terms, including limited abuse-monitoring logs and in-memory caching. Google states that customer data is not used to train or fine-tune its AI models without permission or instruction.

Safety processing. Messages may be screened using keywords and a secondary AI safety assessment to identify possible self-harm, suicide, or harm-to-others risk and show crisis resources. This screening is automated and does not contact emergency services.

Voice input and output. Voice input uses Apple's Speech framework. Depending on device and language support, audio may be processed on-device or by Apple. If you ask the app to read a reply aloud, that reply text is sent through our server to Google Cloud Text-to-Speech to generate audio.

Reports. If you voluntarily report an AI reply, we store the reported content, reason, optional note, time, and account identifier so we can review safety and quality and delete the report with your account.

Subscriptions and usage. Apple processes purchases. We receive verified product, transaction, expiration, revocation, and subscription-status information, plus a count of free AI requests. We do not receive your payment-card details.

Technical information. Our systems may create limited security and diagnostic logs, such as time, response code, and error details. We do not use these logs for advertising profiles.

2. How we use information

3. Service providers and transfers

We use Apple for sign-in, purchases, speech recognition where applicable, and device services; Google Cloud for Vertex AI Gemini and Text-to-Speech; and Oracle Cloud infrastructure in the United States for our backend. These providers process data on our behalf under their applicable terms. Information may therefore be processed outside your country. Where required, we use appropriate legal safeguards for international transfers.

4. Retention and deletion

On-device records remain until you erase them in Settings, delete your account, or remove the app. Server-side subscription and usage records remain while the account exists and as needed for security, legal, and transaction-integrity obligations. User-submitted reports remain only as long as reasonably needed for safety review, unless law requires longer retention.

You can permanently delete your account in Settings → Delete Account. This deletes the account and associated data held by us and erases the app's local account data. Account deletion does not cancel an App Store subscription; subscriptions must be canceled separately in Apple Account settings. You may also revoke Sign in with Apple access in Apple Account settings.

5. Your choices and rights

You can erase local data, delete individual messages, decline microphone and speech permissions, avoid submitting reports, stop voice output, cancel a subscription, sign out, or delete your account. Depending on where you live, you may also have rights to access, correct, erase, restrict, object to, or receive a copy of personal data and to complain to a data-protection authority. Contact us to exercise those rights.

6. Children and wellbeing notice

Lightvessel is not intended for anyone under 17. It is an AI companion, not a medical device, therapist, crisis service, or substitute for professional care. If you may be in immediate danger, contact local emergency services or a crisis service; findahelpline.com can help locate resources.

7. Security, changes, and contact

We use safeguards including HTTPS and account-scoped authentication, but no method of processing is completely secure. We may update this policy and will update the date above or provide an in-app notice for material changes.

8. Website analytics

We use Umami Cloud to understand visits to this website and clicks on selected links and buttons. Privacy-policy and terms pages are excluded from analytics. Statistics include pages viewed, referring websites, campaign tags in links, approximate country, and browser and device categories. Analytics reporting is disabled in the app’s embedded web browser. Website analytics do not access your app records or collect anything you type into website demos. We do not enable session recordings or advertising cookies.

Statistics are processed by Umami Cloud in the United States and retained for up to six months under our current plan. Our tracker respects your browser’s Do Not Track setting and removes URL fragments and query parameters other than standard campaign tags. Read Umami’s privacy information for more details.
