Yes, everything in CotranslatorAI—including the prompts in your prompt library, any text you enter or paste into the fields, and any backups or archives of past AI discussions—remains stored on your local computer. Nothing is uploaded to the cloud or shared with us or anyone else unless you manually do so or use another service outside of CotranslatorAI, such as a cloud backup service. CotranslatorAI never uses intermediary servers and only connects directly to OpenAI with an encrypted, enterprise-grade API connection. OpenAI does not train on your data, and deletes it promptly off their servers, too. You always keep complete ownership and control over your data, so your confidential instructions stay secure, private, and fully under your control.​
