Welcome to EchoWall ("the App"). We highly value your personal information and privacy. This Privacy Policy explains how we collect, use, store, share, and protect your personal information, and how you can manage your data.
Please read this Privacy Policy carefully before using the App. By registering, logging in, or continuing to use the App, you acknowledge and agree to this Privacy Policy.
I. How We Collect and Use Your Personal Information
1. Account Registration and Login
- When you register or log in, we collect your email address, password (transmitted in encrypted form), and account identifiers (such as user ID and login token).
- Purpose: account creation, identity verification, session management, and account security.
2. Profile and Personal Homepage
- You may voluntarily provide or update profile information, such as nickname, avatar, birthday, gender, language, and region.
- Purpose: profile display and better social interaction experience.
3. Content Posting and Interaction Features
- When you use posting, albums, chat, matching, blacklist, reporting, and similar features, we process the content you actively submit, including text, images, videos, and interaction records (such as likes, dislikes, comfort actions, match records, and chat messages).
- Purpose: core community and social functions, content display, interactions, and risk control.
4. Photo Library and Camera Permissions
- When you choose to upload images/videos or take photos for avatars and content materials, we access your photo library or camera after your authorization.
- Purpose: image/video selection, capture, and upload.
- If you deny authorization, you can still use other features that do not rely on these permissions.
5. Location Information (Optional)
- After you grant location permission, we may collect information such as latitude/longitude and country/region code.
- Purpose: account security, risk control, abnormal network environment detection, and service optimization.
- You can disable location permission in iOS settings without affecting basic app usage.
6. Device and Network Environment Information
- To ensure service stability and account security, we collect necessary device and network environment information, including but not limited to device model, OS version, app version, time zone, language, carrier, proxy/VPN status, emulator status, and device identifiers (locally generated and stored using secure system capabilities).
- Purpose: risk control, anti-fraud, troubleshooting, service optimization, and analytics.
7. Payments and In-App Purchases
- When you purchase virtual goods in the App, we process order and transaction-related information, including product identifiers, order numbers, transaction status, and Apple transaction receipt verification results.
- Purpose: purchase completion, reconciliation, fulfillment, refund support, and financial compliance.
- Payments are completed through Apple App Store In-App Purchase. We do not obtain your full bank card or payment account details.
8. Analytics and Attribution
- We may use third-party analytics and attribution services (such as Adjust and Facebook SDK) to measure install sources, campaign performance, and feature performance.
- Subject to applicable laws and system authorization mechanisms, we may process advertising identifiers or attribution information based on your authorization status.
- Purpose: performance analysis, product iteration, anti-fraud, and campaign optimization.
II. How We Use Cookies and Local Storage
- In mobile scenarios, we mainly use local storage mechanisms (such as UserDefaults, App Group shared storage, and Keychain) to store login status, required configuration, and widget display data.
- Purpose: maintaining login status, continuity of use, and widget data synchronization/display.
III. How We Share, Transfer, and Publicly Disclose Personal Information
1. Sharing
We only share personal information when necessary and require recipients to implement sufficient data protection measures. Main scenarios include:
- Cloud service and object storage providers: to store images/videos you actively upload;
- Analytics and attribution service providers: for install attribution, event analytics, and performance analysis;
- Apple: for in-app purchase processing, transaction verification, and settlement;
- Cases required by laws/regulations or lawful requests from competent authorities.
2. Transfer
Unless we obtain your separate consent or otherwise required by laws/regulations, we will not transfer your personal information to other companies, organizations, or individuals.
3. Public Disclosure
We do not publicly disclose your personal information unless we obtain your separate consent or disclosure is required by laws/regulations.
IV. How We Store and Protect Your Personal Information
1. Retention Period
- We retain personal information only for the minimum period necessary to achieve the purposes described in this Privacy Policy, unless otherwise required by laws/regulations.
- After account deletion, we will delete or anonymize relevant information as required by laws/regulations (except where retention is required by law).
2. Security Measures
- We implement reasonable and practical security measures, including encryption in transit, access control, least privilege, and audit logging, to prevent unauthorized access, disclosure, alteration, or loss.

VII. International Transfers
Due to service architecture and cloud infrastructure needs, your personal information may be processed outside your country/region. We will adopt necessary safeguards in accordance with applicable laws to ensure your personal information receives a level of protection consistent with this Privacy Policy.
VIII. Third-Party Services
The App may integrate third-party SDKs or services (including but not limited to Adjust, Facebook SDK, and Apple In-App Purchase services). Third parties may process data according to their own privacy policies. You are advised to read those third-party privacy policies as well.
