We want to share our progress and get early feedback for Contact Cache and that’s why you can use Contact Cache today. We work on Contact Cache every day to improve its core functionality and to add new features.
We feel that Contact Cache is still not a finished product, and that’s why we call it beta. We try very hard to test everything and offer you an amazing product, but we cannot make any guarantees about our service at the moment.
Please note that even that we are still in Beta, all your data are being already encrypted on the client and there should not be any privacy risk even today.
