Privacy Policy

Updated October 21, 2026

Who we are

MusVideo is operated by Beijing Youge Network Technology Co., Ltd. This policy covers the MusVideo mobile app and musvideo.ai. Contact [email protected] for privacy questions and requests.

Information we use

You can purchase credits, generate videos and restore eligible purchases in the mobile app without registering. A random guest identifier and a secret stored securely on your device connect your guest projects and purchase balance; we do not ask guests for a name or email. If you optionally sign in, your guest projects and remaining credits can be linked to that verified account. Account information includes your email, name, account identifier and the Apple or Google sign-in identifier when you use that sign-in method. Email passwords are stored as hashes. Apple authorization tokens needed to revoke access are encrypted. The mobile app offers Apple and email sign-in; available website sign-in methods may differ.

When you create a video, we receive the audio, artist photos, reference images, imported links, prompts, lyrics, project settings and generated results you choose to provide. System pickers give the app access to your selected files; the app does not upload your entire photo or music library.

We keep credit movements, subscription status and transaction identifiers to deliver purchases and prevent duplicate grants. Apple or Google handles mobile payment details, and Stripe handles website checkout. MusVideo does not receive your full card number.

Our servers process request logs, IP addresses, sign-in activity, technical errors and generation status to operate the service, prevent abuse and resolve problems. Website cookies and attribution information may support website sessions and campaign measurement. The native app uses Apple AdServices for Apple Ads measurement. App versions with TikTok advertising measurement request your permission through Apple App Tracking Transparency before using IDFA or sharing personal tracking events with TikTok.

AI processing and your choice

Before the mobile app sends your selected media or prompts for analysis or generation, it asks for explicit permission. You may decline and browse the app, or withdraw permission in You → Privacy & AI. Withdrawal stops new AI requests from the app; use Stop to cancel a running Director task. It does not recall processing already delivered to a provider. On the website, choosing an analysis, generation or refinement action sends the relevant project data to the services described below.

Depending on the chosen model and service configuration, media and prompts are sent to KIE.AI, OpenRouter or EvoLink and the model providers they route requests to, such as Google, for music analysis, creative suggestions, images and video. The permission screen lists these services and why they receive data. Our OpenEva-based MusVideo Director runtime stores project context, conversation history, tool inputs and outputs, and resumable session files. Director uses the configured text model through our model gateway for story planning and refinements. Relevant lyrics, story text, settings and reference descriptions are sent as context. For the new workflow, AssemblyAI transcribes the selected audio, including available word timing. The Director uses Anthropic Claude through our model gateway for story planning, storyboard prompts and self-review in one context, including relevant reference images. The Director stops after saving the plan; image and video generation run when you request them. OpenRouter routes image and video generation to the configured providers. Older workflows may use DeepSeek for planning or review. Final video composition runs on our own servers using FFmpeg, combining your selected song and clips without subtitles. Cloudflare and our hosting providers store and deliver files and operate the service.

Only provide music, images and likenesses you have permission to use. Reference photos are used to guide generation, not to identify you. Avoid including sensitive information in prompts or media. Provider processing, retention and any model-training practices are governed by their policies; we do not promise zero retention by every provider.

Purchases and service providers

RevenueCat receives a pseudonymous MusVideo purchase-account ID and store purchase history to validate receipts, restore entitlements, handle refunds and provide purchase analytics. We do not send your email, artist photos or music to RevenueCat. For Apple Ads measurement, the app sends a short-lived Apple attribution token to RevenueCat and to MusVideo, which verifies it with Apple. We record a random installation identifier, first observed app open, Apple campaign, ad group and keyword identifiers when available, country or region, download type and associated purchase amounts. This helps us measure campaign performance; Apple may return no attribution. MusVideo does not store the raw attribution token. Account deletion removes MusVideo’s installation attribution and its link to retained transaction records. Sandbox purchases use separate test credits and projects.

We share information with service providers as needed to operate MusVideo, comply with lawful requests and protect the service. We do not sell personal information. Optional TikTok app advertising measurement is described below and is subject to your iOS tracking permission. Data may be processed outside your country, subject to applicable protections.

TikTok website advertising measurement

On musvideo.ai, TikTok advertising measurement is enabled by default unless you turn it off or your browser enables Global Privacy Control. When enabled, TikTok receives website activity such as page visits, completed registrations and verified purchases, together with technical information such as browser details, IP address, cookies and advertising click identifiers. Purchase events include the plan, amount and currency. We do not include your email, phone number, uploaded music, photos or project prompts in these event fields. This helps us measure and improve TikTok advertising. Website privacy choices are separate from iOS tracking permission for the native app.

You can turn this measurement off or on using TikTok ad privacy in the footer. Turning it off stops future event sharing but does not recall data already shared. We remember your choice for up to 180 days and honor Global Privacy Control. This control applies to the TikTok integration. See TikTok’s privacy policy for its processing practices.

TikTok mobile app advertising measurement

In app versions with TikTok App Events SDK, and only if you allow tracking through the iOS permission prompt, TikTok receives app installation and opening events, new account registration, first successful video generation, and verified purchase events. This can include device and advertising identifiers, a pseudonymous account identifier, IP address and device information, and the purchased product identifier. We do not send your email, phone number, music, photos, video files, lyrics or project prompts in these event fields. We use this data to measure and improve our advertising.

You can decline or change tracking permission in iOS Settings without losing access to MusVideo. Declining stops personal tracking event sharing with TikTok; it does not recall information already shared. Apple SKAdNetwork may provide delayed, aggregate advertising attribution without sharing personal tracking identifiers. The app’s AI processing permission is separate from advertising permission.

Retention and account deletion

Your account and saved projects remain available while you use the service. Guests can choose You → Delete guest data without creating an account. A store restore restores eligible purchase rights and remaining verified purchase credits; it does not reveal another account’s personal profile or projects. Sign-in is optional and enables project access across devices. In the app, choose You → Delete account, review the consequences and verify your identity. Because the app and website share a user account, deletion closes that account on both. You may also request access, correction, export or deletion through [email protected].

Account access is disabled and identifying profile information and project records are removed when deletion is accepted. Director records, context snapshots, conversation history and workspace session files are included in account and project deletion. Running Director tasks are stopped and cleanup retries if a service is unavailable. Media cleanup and authorization revocation are queued for completion within 30 days; legacy files may require an ownership check. We retain limited transaction and fraud-prevention records where needed for legal, accounting or dispute obligations, with access restricted. Backups and provider-held copies follow their retention schedules and are not used to restore an active account.

Deleting your MusVideo account does not cancel an Apple, Google or website subscription. Cancel it in the store where you subscribed. Copies you exported, shared publicly or gave to others cannot be recalled by deleting your account.

Your rights and security

You can access your profile, manage subscriptions, withdraw AI permission and request deletion. Depending on your location, you may also have rights to portability, restriction, objection or a complaint to a privacy regulator. Contact [email protected]; we may verify identity before acting.

We use HTTPS, access controls and protected credentials to reduce risk. No system can guarantee absolute security. MusVideo is not directed to children under 13; users must also meet applicable local age requirements. Contact us if a child has provided personal information. Material policy changes will be reflected here and, where needed, presented in the app.
