 1. Your embeddings are generated by an open source model within our own dedicated endpoint [hosted on AWS with Huggingface](https://huggingface.co/inference-endpoints/dedicated). There's zero persistent memory to the Huggingface Inference endpoints (it's stateless).
 1. Your embeddings and the associated raw text are stored in a secure Postgres DB in our private AWS cloud. Your data is sharded on a unique user ID. We store the raw text in your files to improve file syncing and provide context when you chat with Khoj.
 1. When you use the single-sign-on option with Google, we only receive your name, a link to your profile photo, and your email address.
