T-Lang ("the Service") provides server-side prompt compression for Large Language Model (LLM) API calls. The Service compresses your prompts before your CLI sends them to your chosen LLM provider (OpenAI, Google Gemini, xAI Grok, DeepSeek, Groq, etc.), reducing token consumption and associated costs.
The Service is operated by an independent developer. For questions or support, please open an issue at github.com/ninja9998877/t-lang.
You must register for an account (via email/password or Google sign-in) to use the Service. You are responsible for keeping your T-Lang API key secure. Your LLM provider API keys (e.g., OpenAI key) are stored only on your local machine and never sent to T-Lang servers. You are responsible for all usage under your account.
We reserve the right to modify pricing with 30 days' notice. Existing subscribers will be notified via email before any price changes take effect.
Pro subscriptions may be cancelled at any time and will remain active until the end of the current billing period. Refunds are available within 7 days of the initial subscription purchase if no more than 50 compressions have been used.
T-Lang processes your prompts in-memory on Cloudflare's edge network to apply compression. We do not store, log, or retain the content of your prompts. Your LLM provider is called directly by the CLI on your machine — responses never pass through T-Lang servers. We only store aggregate usage statistics (token counts, request counts) for billing and analytics purposes.
