1. Scope and controller
This Policy applies to WeSync for iOS and Android and related services. The personal information controller is Shanghai ProxiVisual Technology Co., Ltd (上海零距光影科技有限公司, “we,” “us,” or “our”).
This Policy does not govern cloud drives, video websites, or other third-party services opened through the in-app browser. Those providers independently process login details, cookies, files, memberships, and payment information under their own policies. A feature-specific notice may supplement this Policy and governs that feature where it is more specific.
2. Information we process and why
2.1 Registration, sign-in, and security
To create accounts, authenticate, recover or change passwords, and bind or change contact methods, we process contact details, authentication and verification information, session state, and necessary account-security records. If you choose Google Sign-In, we receive the profile information you authorize Google to provide. Passwords and one-time codes are used for verification and are not stored by us in plaintext.
2.2 Profile and social graph
We process account identifiers, display name, avatar, contact information where needed for identity mapping or search, friend requests, and relationship status to provide profiles, user search, and friend features. An avatar you choose is uploaded for display.
2.3 Messaging
We process conversation relationships, communications, message types, timestamps, and delivery and read status to provide messaging. Messages are retained on the device and server as necessary for history and multi-device synchronization.
2.4 Rooms and synchronized viewing
We process room, member, role, and online-status information, along with the playback and resource information needed to provide synchronization.
Local video: The app reads a file you explicitly select and its name for local playback and matching. The video file itself is not uploaded to WeSync or forwarded to members.
Cloud-drive viewing: At the host's direction, we may process and synchronize the provider, share details, resource name, and playback state. Room members can see this information.
2.5 Voice and room interaction
When you join a call and enable the microphone, we process real-time voice and the status information necessary to provide calls and room interaction. Voice is not recorded or retained as a message by default. Only information required by law or for security and operations may remain after a call.
2.6 Push notifications
With system permission, we process the information needed to identify an app installation and deliver notifications for messages, friends, invitations, calls, and service notices. Historical notification credentials may be kept where necessary for older-client compatibility. You may disable notifications in system settings.
2.7 Subscriptions
To verify benefits, restore purchases, prevent fraud, and process refunds, we handle necessary order, product, transaction-proof, and subscription-status information. The app store processes full payment-card information; we do not receive it.
2.8 Analytics, logs, and feedback
For reliability, debugging, security, and feature measurement, we may process account identifiers, feature usage, timing, relevant web information, and feedback content. We may also record necessary network, device, request-result, and error information. We do not use this information for third-party advertising profiles.
2.9 On-device preferences
The app stores information needed for sign-in, personal settings, bookmarks, message history, language and theme, and feature preferences on the device. Uninstalling ordinarily removes most local data, subject to operating-system backup or secure-storage behavior.
2.10 Legal bases
We process information to perform our contract with you, with consent, to meet legal obligations, to protect persons and property, and on other grounds permitted by applicable law. You may refuse or withdraw optional consent and permissions. Withdrawal does not affect prior lawful processing.
3. Device permissions
| Permission | Purpose | Optional? |
|---|---|---|
| Microphone | Room voice calls, only when you join and enable audio. | Yes. Refusal disables outgoing voice. |
| Camera | Take a profile image; iOS configuration also anticipates possible video-call use. Android currently removes foreground-service camera permission. | Yes. Choose an existing image or omit an avatar. |
| Photos, media, and files | Select an avatar, local video, image, or file to send. | Yes. Access is limited to your selection or system-authorized scope. |
| Notifications | Messages, friends, invitations, calls, security, and service notices. | Yes. Change in system settings. |
| Overlay, full-screen intent, vibration, wake, and foreground service (Android) | Timely incoming-call display and maintaining a necessary call connection. | Yes. Background call alerts may be incomplete. |
| Media library (iOS) | Access system music only when you use the relevant media-sharing feature. | Yes. Other features remain available. |
Permissions are requested in context and are not granted merely by accepting this Policy. Manage them under your device's application settings.
4. Local processing, in-app browsing, and cookies
The in-app browser is provided through the device's system web component. Websites independently process network, device, cookie, login, browsing, and interaction information under their policies. To identify synchronizable video and provide watch-together features, the app locally processes necessary playback state and resource information you choose to share. We do not access page content for the purpose of obtaining third-party account passwords.
Website cookies, cache, and site storage remain on the device under system controls. Manage them by signing out of the site, clearing application data, or uninstalling the app. This legal website uses no advertising or analytics components and sets no cookies; a manual language choice is remembered only for the current browser session.
6. Categories of third-party services
Availability depends on platform, region, client version, and service configuration. We provide only the information necessary for the relevant function.
| Service category | General information category | Purpose |
|---|---|---|
| Account authentication and third-party sign-in, including Google Sign-In | Information needed for registration, sign-in, identity verification, and profile display | Account access, security verification, and third-party sign-in |
| Mobile notification services, including JPush and operating-system push services | Information needed to identify an app installation and deliver a notification | Messages, invitations, calls, and service notices |
| Real-time communications services | Information needed to provide calls and room interaction | Voice calls and real-time room interaction |
| SMS verification services | Mobile number and information needed to complete verification | Phone registration, sign-in, and security verification |
| Apple App Store / Google Play | Information needed for orders, transactions, and subscriptions | Purchase, renewal, restoration, and refund verification |
| Content storage and delivery services | User-provided content and information needed to make it available | Store and display avatars and similar user content |
| Operations and security services | Information needed for operation, diagnostics, and security | Reliability, troubleshooting, and security auditing |
| Cloud drives and video websites you visit | Information independently processed by the third party under its policy | Independent web, cloud, video, and membership services |
Third-party services and their processing rules may change. Refer to each provider's official channel for its current privacy terms.
7. Storage, retention, and international transfers
Depending on service configuration, information is stored in facilities in China or other locations lawfully available to us. Some independent third-party services may process information outside China. We take measures required by applicable law.
We retain information only as long as needed: account, profile, social, conversation, and subscription records during the account term and applicable legal period; messages until lawful deletion, conversation cleanup, or account-deletion processing; room-interaction state while needed for the feature, with necessary room records retained for continuity and audit; notification, operational, analytics, and feedback information for delivery, diagnostics, security, statistics, and legal needs; and transactions for tax, financial, consumer, and store obligations. Expired data is deleted, anonymized, or isolated as legally required, including through backup rotation.
8. Security
We use safeguards appropriate to the risks of the Service, including identity verification, encryption, access control, security auditing, backups, and updates. Information stored on a device is protected by the security mechanisms provided by its operating system. No internet service can be absolutely secure. Use strong credentials, protect verification codes and room/share information, and keep software updated. If an incident may materially affect you, we will mitigate and notify as required by law.
9. Your rights
Subject to applicable law, you may:
- access and obtain a copy of relevant information;
- correct or complete your name, avatar, email, phone, and password;
- request deletion where information is unnecessary, unlawfully processed, or consent has been withdrawn;
- withdraw consent by disabling permissions, signing out, or stopping the relevant feature;
- request account deletion using the email address in this Policy, subject to ownership verification, outstanding subscriptions or disputes, and legal retention;
- request an explanation, restriction, object, complain, or appeal.
We generally respond within 15 working days. We may decline or limit requests where identity cannot be verified, a request is manifestly unreasonable, another person's rights would be harmed, or law requires retention, and will explain where appropriate.
10. Children
WeSync is not directed primarily to children under 14. A child must use it with express guardian consent and supervision. We process children's information only as necessary for the Service and not for targeted advertising. A guardian who believes information was provided without consent should contact us with sufficient verification so we can delete or protect it as required.
11. Changes to this Policy
We may update this Policy for product, legal, or provider changes. Material changes to purposes, methods, categories, or rights will be highlighted through an in-app notice, announcement, push, or another prominent channel, and we will obtain renewed consent where required. Prior versions will be archived for a reasonable period.
