Privacy Policy
Last updated: October 19, 2026 · Operator: lida
About this policy
Weiyang is operated by lida, an individual developer. This policy explains how we handle personal information in the Weiyang app and website. Weiyang provides AI character conversations, storytelling, memory and text-to-speech features for users aged 18 or older. Please read this policy before using the service.
Account and device information
When you sign in, we process the identity identifier returned by the sign-in provider and profile information you provide, such as a nickname or avatar, to create and recognize your account. Guest use also creates an account identifier. To maintain sessions and account security, we process device identifiers, device names, platform, region settings and recent activity times. Region settings are not precise location data. The relevant sign-in provider verifies third-party sign-ins.
Characters, conversations and memory
We process and store character settings, messages, conversations, story branches and related memories on our servers so you can save and continue your conversations. To generate replies, we use the necessary character settings, conversation context and relevant memories. When memory is enabled, the system may extract, retrieve and update memories from your conversations. You can review, edit or delete memories, or pause personalized memory. Please avoid sharing unnecessary identity documents, passwords, financial account information or sensitive information about other people.
AI and speech providers
Weiyang uses Qwen models through OpenRouter and Alibaba Cloud Bailian. Necessary text and context are sent to the relevant providers to generate replies, summaries and memories, or to support retrieval. For text-to-speech, the text to be read is sent to Alibaba Cloud Bailian to synthesize audio. Generated audio is cached on our servers for playback. OpenRouter may route requests to model providers. These providers handle received information under their own terms and privacy policies. Processing locations and retention practices depend on the services used.
Images and local storage
Personal character covers you select in the creation feature and local drafts are stored on your device. This feature does not upload those cover images to Weiyang servers. Device backups may include this data, depending on your system settings. Character artwork supplied by Weiyang is served from our servers. You can manage photo access through your device settings. Removing the app or its local data may delete local covers and drafts that have not been synchronized.
Purchases and subscriptions
Apple App Store processes iOS in-app purchases. We process transaction identifiers, products, purchase verification information and subscription status to verify purchases, restore entitlements and prevent duplicate grants. We do not directly process your payment card number. Renewals, cancellations, refunds and subscription changes are governed by Apple’s purchase rules and processing results. Deleting a Weiyang account does not cancel an App Store subscription; manage subscriptions separately through Apple.
Support, safety and operational records
When you submit feedback or a report, we process the contact information, issue description and relevant content you provide to contact you and address the issue. Necessary evidence of reported violations may be retained for safety review. Operational records include request times, endpoints, errors, usage and necessary network or device information to protect the service, troubleshoot problems and account for usage. Conversation text is not written to analytics logs.
Sharing and safeguards
We pass necessary information to relevant providers when needed to offer features such as sign-in, AI generation and payments. Information may also be disclosed as required by applicable law or to address security incidents. We use authentication, access controls and transport protection to limit unauthorized access. No system can guarantee absolute security. You can read product information, policies and support pages on this website without signing in.
Retention and account deletion
We retain information for as long as necessary to provide the service and meet security, financial and legal requirements. You can delete messages, conversations, characters or memories in the app, or request account deletion in account settings. Your account is disabled immediately after a deletion request. A cleanup task is scheduled for seven days after the request to process private content and identity information. Necessary transaction records and the account deletion status may be retained. Related audio caches are deleted through cleanup tasks. Local covers and drafts must also be managed through the app or your device’s storage settings.
Your rights and choices
Use profile, memory, privacy and account settings in the app to review and manage information, pause memory or request account deletion. Contact us for access, correction, deletion or other privacy requests that you cannot complete in the app. We may ask for information necessary to verify account ownership and prevent unauthorized requests.
Age requirements and updates
The service is intended only for users aged 18 or older. Please contact us if you believe a minor has provided personal information to us. We will update this policy and its date when our features or information handling practices change, and provide appropriate notice of material changes.
