Terms of Service

Last Updated: November 18, 2025

These Terms of Service ("Terms") govern your access to and use of the peer-to-peer encrypted file transfer and messaging application ("Service"). By installing, accessing, or using the Service, you agree to be bound by these Terms. If you do not agree, you may not use the Service.

1. Description of the Service

The Service enables users to:

  • •transmit files and folders directly to one another using peer-to-peer technology, and
  • •exchange text messages, media, and other communication ("Messages") using encrypted communication channels.

Transfers and Messages are encrypted end-to-end where technically feasible. The Service does not store message content or file contents on central servers, except transiently and only if required for routing, delivery, or reconnection.

2. Eligibility

You must be the age of majority in your jurisdiction and have legal capacity to enter a binding agreement. If acting on behalf of an organization, you confirm you are authorized to bind that organization.

3. User Responsibilities

You agree to:

  1. •Use the Service only for lawful, non-abusive purposes.
  2. •Ensure you have rights to any files or content you send.
  3. •Not use the Service to transmit harmful, unlawful, infringing, harassing, or malicious material.
  4. •Avoid interfering with, modifying, or attempting to bypass any security, encryption, or rate-limiting systems.
  5. •Maintain secure devices, passwords, and access to your account or encryption keys.

You acknowledge that you are solely responsible for your Messages and files.

4. Content Ownership

You retain full ownership of your files, folders, and Messages. The provider does not claim ownership and does not monitor or view content except automatically and temporarily as needed for technical operation, such as message queuing, routing, or encryption key exchange.

5. Messaging Functionality

5.1 Nature of Messaging

The Service provides encrypted messaging between users, including but not limited to:

  • •one-to-one chats
  • •group messaging (if enabled)
  • •text, media, and attachment exchanges

5.2 Encryption

Messages are encrypted end-to-end where supported. This means:

  • •message content is intended to be readable only by intended recipients;
  • •the provider cannot access message content;
  • •some message metadata (e.g., timestamps, sender/receiver identifiers, routing details) may be processed for delivery and system functionality.

5.3 Message Delivery

Messages may be temporarily cached, encrypted, on servers solely to facilitate delivery when a recipient is offline. These temporary caches, if used, are automatically cleared after a short retention period.

5.4 User Responsibility for Messaging

You agree not to use messaging functionality to:

  • •send spam, threats, hate speech, or harassment;
  • •distribute malware or harmful links;
  • •coordinate unlawful activity;
  • •violate privacy, intellectual property, or data protection laws.

6. Encryption and Security

The Service is designed to protect your files and Messages using modern cryptographic methods. However:

  • •absolute security cannot be guaranteed;
  • •fallback relay servers or message queues may be required under certain network conditions;
  • •you are responsible for protecting your device, keys, and passwords.

The provider is not liable for unauthorized access resulting from your failure to secure your device or credentials.

7. Unlimited File or Folder Size

The Service aims to support unlimited file and folder sizes. Real-world performance depends on device capability, network quality, and recipient conditions. Technical limits may be applied to maintain system integrity or prevent abuse.

8. Service Availability

The Service is provided on an "as-is" and "as-available" basis. Messaging and file transfers may experience delays, throughput variations, interruptions, or failures due to network or technical limitations.

The provider may modify, suspend, or discontinue features at any time.

  • •harass, defraud, or harm others;
  • •attempt unauthorized monitoring or surveillance;
  • •disrupt the network or infrastructure.

Violations may result in termination.

11. Third-Party Software & Networks

The Service may rely on third-party libraries or network infrastructure. The provider is not responsible for failures, vulnerabilities, or changes introduced by such components or by the networks used for file transfer or messaging.
