1. Information We Collect

When you interact with JW, we may collect several types of information:

1.1 Information You Provide Directly

  • Account Registration: When you register an account, you may provide personal details such as your name, phone number, email address, payment or bank card information, and other identifiers.
  • User-Generated Content: Any content you upload or share through our services (e.g., photos, messages, documents) is information you provide.
  • Communications: When you contact customer support, participate in surveys, or communicate with other users via our platform, we collect the content, timestamps, and associated account identifiers.

  • Log Data: We receive and store technical information your device sends whenever you access our services. This may include:
    • Device type and operating system version
    • Browser type and version
    • IP address
    • Unique device identifiers (e.g., device ID)
    • Date/time stamps and log data (pages viewed, search terms, referral URLs)
  • Usage Data: We track how you interact with our services—what features you use, how often you use them, and performance data to help us optimize user experience.
  • Location Data: With your permission, we may collect precise or approximate geographic location from your device’s GPS, Wi-Fi, or cell tower signals. You can disable location sharing in your device settings at any time.

1.3 Information from Third-Party Sources

  • Shared by Other Users: If another user shares information about you (for example, in a social context), we may collect that.
  • Partner Data: If you log in with or link a third-party account (e.g., social media login), we may receive profile information, friend lists, or other details from that provider, subject to your permissions.
  • Publicly Available Sources: We may supplement our records with information available from public sources (e.g., professional directories) to keep our data accurate and up to date.

2. How We Use Your Information

We use the information described above to:

  1. Provide and Maintain Services
    • Verify your identity, manage your account, and facilitate customer support.
    • Deliver requested features (e.g., messaging, content sharing, personalized settings).
  2. Ensure Security & Prevent Fraud
    • Monitor for suspicious activity, detect and prevent fraud, and secure our systems.
    • Maintain logs and backups for legal and compliance purposes.
  3. Improve & Develop New Services
    • Analyze usage patterns to identify areas for improvement, fix bugs, and enhance performance.
    • Tailor user experience by remembering your preferences (e.g., language, region) and suggesting relevant features.
  4. Personalization & Advertising
    • Offer personalized content and recommendations.
    • Show you interest-based ads (only if you opt in). We evaluate ad performance and may provide aggregated, de-identified data to advertisers.
  5. Aggregate & Cross-Service Uses
    • With your consent (where required), use data collected from one JW service to enhance another. For example, preferences stored in Service A may improve recommendations in Service B.
  6. Legal & Compliance Obligations
    • Comply with applicable laws, regulations, legal processes, or governmental requests.
    • Enforce our Terms of Service and protect our legal rights and those of our users.

3. How You Can Access, Update, or Delete Your Information

  • Account Dashboard: You can review and update most of your profile and account settings by logging into your JW account and visiting Account Settings.
  • Correction Requests: If you believe any information we hold about you is inaccurate or incomplete, contact us; we will respond in accordance with applicable law.
  • Deletion: You may request deletion of your personal information by contacting our Data Privacy team. We may require you to verify your identity before processing such requests.
  • Retention: We retain personal data only as long as necessary for the purposes outlined in this Privacy Policy and in compliance with applicable laws. Once data is no longer needed, we securely delete or anonymize it.

4. Information Sharing & Disclosure

We will not share your personal information with third parties except as described below:

4.1 Affiliates & Service Providers

  • We may share your personal information with:
    • Affiliated Companies: Entities under common ownership, for purposes consistent with this Privacy Policy.
    • Service Providers & Contractors: Third parties who perform services on our behalf (e.g., payment processors, email gateways, cloud hosting providers, customer support vendors). These partners are contractually obligated to use your data only to provide the requested service and to maintain confidentiality.

4.2 Business Transfers

  • In the event of a merger, acquisition, asset sale, or bankruptcy, your personal information may be transferred to the acquiring entity. We will notify you ahead of any such transfer whenever required by law.

  • We may disclose your information when:
    • Required by Law: To comply with a subpoena, legal process, court order, or government request.
    • Protecting Rights: To protect the rights, property, or safety of JW, our users, or the public.
    • Investigations: To detect, prevent, or address fraud, security, or technical issues.

4.4 Aggregate & De-Identified Data

  • We may share aggregated or anonymized usage statistics with partners, advertisers, or the public. This data cannot be used to identify you personally.

5. Information Security

  • Encryption: We employ industry-standard encryption (e.g., TLS/SSL) to protect data in transit.
  • Access Controls: Access to personal data is restricted to employees, contractors, and partners who need it to perform their jobs and are bound by confidentiality obligations.
  • Data Retention & Disposal: We retain data for as long as necessary to fulfill the purposes outlined in this policy or as required by law. Once no longer needed, we securely delete personal data.
  • Risk Mitigation: Despite our best efforts, no system is completely immune to vulnerabilities. We conduct regular security assessments and update our infrastructure to defend against unauthorized access, use, or disclosure.

6. Your Information That You Share Publicly

  • Content You Post: When you share photos, messages, or other content, that information may be visible to other users or publicly accessible, depending on your privacy settings.
  • Location in User Content: If you embed location data (e.g., geotags in photos), others may see it. Review your privacy settings to control who can view your location.
  • Irreversible Sharing: Once you share publicly, third parties may copy, cache, or store your content independently; deleting content from our servers does not guarantee full removal from external sources. Always consider carefully what you choose to share.

7. Sensitive Personal Information

Some data—such as racial or ethnic origin, religious beliefs, health or medical information—may be categorized as “sensitive personal information” under local laws. We do not require you to disclose sensitive data. If you choose to provide it, you consent to us handling it in accordance with this policy and applicable law. Please think carefully before sharing such details on our platform.
