Private Session 23:59

Is this conversation really private?

Absolutely. No logs are kept. When your session ends, all data is securely wiped. Even the operators can't access your conversations.

What happens when my session expires?

Why OTR404?

Built from the ground up for privacy. No compromises.

Zero Logging

We don't store your conversations. Period. No database entries, no backups, no traces.

End-to-End Encrypted

Your messages are encrypted in transit and at rest. Only you and the AI can read them.

Ephemeral Sessions

Sessions auto-destruct. When time's up, memory is securely wiped using military-grade techniques.

No Tracking

No cookies, no analytics, no fingerprinting. We don't know who you are, and we like it that way.

Open Source Models

Powered by GPT-OSS and Qwen models. No proprietary black boxes. Full transparency.

Optional Safety

Content filtering is your choice. Enable or disable it based on your needs. Your rules.

How It Works

Privacy through architecture, not promises.

01

Start a Session

Create an account and purchase session time. Your credentials are hashed — we can't read them.

02

Chat Privately

Your session runs on an isolated server. Messages exist only in memory, never touching disk.

03

Session Ends

Timer expires or you end the session. The server's memory is cryptographically wiped.

04

Infrastructure Destroyed

The entire server instance is terminated. No forensic recovery possible. Gone forever.

Simple, Honest Pricing

Pay for what you use. No subscriptions. No hidden fees.
