Privacy Policy

1. Peer-to-Peer Architecture

Textunnel operates as a client-side peer-to-peer (P2P) utility. When transferring files, photos, videos, or text between devices on the same local network (Wi-Fi/LAN) or over the internet, payloads stream directly from device A to device B via WebRTC DataChannels.

2. Cryptographic Data Encryption

All communications are encrypted end-to-end by default using standard DTLS 1.2/1.3 and AES-GCM cipher suites. Encryption keys are generated locally in the browser of the connecting peers. Neither Textunnel nor any intermediate party can inspect or decrypt the contents of your transfer.

3. Zero Cloud Storage & Zero Data Retention

We do not store, save, or cache your files, documents, or clipboard history on any central database or cloud disk. Once a browser tab is closed or a transfer session ends, all session contexts and ephemeral room IDs are destroyed immediately from volatile browser memory.

4. Signaling Server Operations

To establish the initial WebRTC peer connection (the handshake), a lightweight signaling server relays connection metadata (such as Session Description Protocol / SDP packets and ICE candidates). The signaling server never processes, inspects, or stores the actual file or clipboard payload.

5. Third-Party Advertising and Cookies (Google AdSense Compliance)

We partner with third-party advertising companies, including Google AdSense, to display advertisements when you visit our website. These companies may use cookies and similar technologies to collect non-personally identifiable information regarding your browsing activity on this and other sites to provide relevant advertisements:

• Third-party vendors, including Google, use cookies to serve ads based on prior visits to our website or other websites across the internet.
• Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to our site and other sites on the web.
• Users may opt out of personalized advertising by visiting Google's My Ad Center.
• Alternatively, you can opt out of third-party vendor cookies for personalized advertising through the Digital Advertising Alliance (DAA) or the Your Online Choices portal.

6. GDPR & CCPA Compliance

Under the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), you have the right to know what personal data is processed. Because Textunnel requires no user registration and retains zero personal data or transfer archives, we do not maintain identifiable user databases.
