Security at PromptDC
PromptDC is designed to protect everyone who uses it for clearer prompts and writing. We prioritize safe data handling, secure access controls, and transparent reporting channels.
Our Mission
PromptDC is a universal AI prompt enhancer for coding and writing. Its Chrome extension improves prompts, grammar, emails, replies, and social posts directly in the text box where you work.
Bring your own key
On the Lifetime plan you use your own provider API key. It's kept in your browser's local storage and pushed to the PromptDC extension — not persisted on our servers — and is sent through PromptDC's backend to your chosen provider with each request.

The enhanced text returns where you work
For Lifetime requests, your BYOK key travels through the PromptDC backend to the provider you selected. PromptDC never stores the key on its servers.
Security Highlights
All internal tools and restricted areas are protected by robust authentication and are hidden from search engines.
Your API keys live in your browser's local storage (and the PromptDC extension), not persisted in our database. To run an enhancement, your key is sent through PromptDC's backend to your chosen provider for that request — usage is billed to your own provider account.
Built on modern, hardened stacks designed for scale and resilience against common attacks.

PromptDC uses a small set of subprocessors for core product operations.
