Engula is an in-memory database designed to be privately deployed by you in your own environment (for example, on your own servers, infrastructure, or local machines). Engula is designed for self-hosting and private deployment. We do not operate or offer Engula as a hosted online service in which we control your data.
When you run Engula in your own environment, any data you store in Engula is controlled by you. Unless you explicitly send data to us (for example, by providing logs or sample data as part of a support request), we cannot access the data in your private deployment.
For this reason, this Privacy Policy primarily focuses on:
