Privacy Policy

Deep Sent is designed as a direct, non-persistent, one-time message delivery tool. We value your privacy and this policy explains how information is handled while using Deep Sent.

1. Product Design Principles

• Messages are sent one-way only (no conversations)
• No contact lists or social connections are created
• No long-term storage of message content locally or on servers
• Delivery completes the message lifecycle; messages cannot be recovered

2. Information We Collect

During normal use of Deep Sent:

• We do not collect, read, or analyze your messages
• We do not store any communication history
• We do not build social graphs or user profiles

To ensure basic functionality, minimal necessary information may be used, including:

• Device information (OS version, device model) for compatibility and stability
• System-generated push tokens used solely for message delivery

3. Message Handling

• Messages exist only temporarily during transmission
• Delivered messages are automatically cleared
• Messages cannot be retrieved, viewed again, or restored

4. Third-Party Services

Deep Sent may rely on compliant system-level services for essential functionality, such as:

• Apple Push Notification Service (APNs)

These services are used exclusively for message delivery and do not store any content.

5. Data Security

We take reasonable technical measures to protect message transmission. However, since Deep Sent does not store messages, delivered messages cannot be retrieved.
