EVICAM Privacy Policy

Last Updated: August 12, 2025

Introduction

Welcome to EVICAM, a secure, verified media sharing application owned and operated by ZDTech LLC ("we," "us," or "our"). This Privacy Policy explains how we collect, use, disclose, and protect your information when you use the EVICAM mobile application and website (collectively, the "Service"). By using the Service, you agree to the practices described in this policy.

Information We Collect

Personal Information

We may collect the following personal information when you use the Service:

  • Account Information: Phone number, name, and email address (if provided) during registration or account management.
  • Contact Information: Access to your contacts to facilitate sharing, with your explicit permission.
  • Payment Information: Transaction details for token purchases via Apple App Store or Google Play Store, processed securely by third-party payment providers.

Verified Media and Metadata

When you capture photos or videos in-app:

  • Media Files: Images and videos (up to 10 seconds) stored securely in AWS S3 with end-to-end encryption (E2EE).
  • Metadata: GPS location, date, time, device details, resolution, compression details, and GPS accuracy, embedded in media for verification.

Other Data

  • Messages: Text chats stored in Firebase Firestore, encrypted with AES-256-GCM using ECDH-derived session keys.
  • Token Transactions: Records of token balances and purchases stored in Firestore for analytics and validation.
  • Usage Data: Device information, IP address, app interactions, and analytics to improve the Service.

How We Use Your Information

We use your information to:

  • Provide and maintain the Service, including media capture, encryption, and sharing.
  • Verify media authenticity using metadata and cryptographic signatures.
  • Process token purchases and manage sharing limits (e.g., 4 free images, 1 web share/day).
  • Facilitate secure communication via E2EE chats and password-protected web links.
  • Improve the Service through analytics and troubleshoot issues.
  • Respond to your inquiries via support@evicam.app.

How We Protect Your Information

We prioritize your privacy and security:

  • End-to-End Encryption: Media and messages are encrypted using AES-256-GCM with ECDH-derived keys stored securely in SharedPreferences (encrypted) and Firebase Firestore.
  • Screenshot Deterrence: Features like Android FLAG_SECURE and iOS detection to prevent unauthorized captures.
  • Secure Storage: Media stored in AWS S3 with pre-signed URLs (5-minute expiry) and watermarks.
  • Access Controls: Only authorized users (via UIDs or password-protected links) can access shared media.

Sharing Your Information

We do not sell your personal information. We may share information:

  • With your consent, e.g., when sharing media with contacts or via web links.
  • With service providers (e.g., AWS, Firebase, Apple/Google for payments) under strict confidentiality agreements.
  • To comply with legal obligations or protect our rights.

Your Choices

You can:

  • Manage permissions (camera, location, storage, contacts) in the app or device settings.
  • Delete chats or media, which removes data from your subcollection and S3 (if shared).
  • Export your private key (as evicam_userphonenumber_secret.txt) for backup.
  • Delete your account via Settings, which removes personal data from our systems (subject to legal retention).

Data Retention

We retain personal information and media as long as your account is active or as needed to provide the Service. Deleted chats or media are removed from Firestore subcollections and S3. Token transaction records may be retained for analytics or legal purposes.

International Data Transfers

EVICAM operates globally, and your data may be processed in the United States or other regions (e.g., AWS S3, Firebase). We comply with applicable data protection laws, including GDPR for EU users, using safeguards like encryption and standard contractual clauses.

Children's Privacy

The Service is not intended for users under 13. We do not knowingly collect data from children under 13. If you believe we have such data, contact us at support@evicam.app.

Changes to This Policy

We may update this Privacy Policy to reflect changes in our practices or legal requirements. We will notify you via email or in-app notice. Continued use of the Service after changes constitutes acceptance.
