End to End encrypted chats

Have you considered adding an end to end encryption / upgraded privacy mode where you don’t log chats and store then using user provided keys, even if it had a higher price tag associated with it? This could increase the feasibility of adoption by companies who require retaining confidential information. Your privacy policy mentions you do collect user content. I’m not sure if you already employ some nature of encryption at rest, but this might be a useful middle ground, or be helpful to mention in your privacy policy.
