Extra Data Storage
Extra Admin Users
One device can be logged into a User account at one time. You may allow multiple staff to share a single account at different times, however it could inhibit the use of Activity logs and other User specific features.
You can store up to 750,000 records in 1 GB, dependent on the size of each record. Files/images generally take more space than other records. You can estimate your storage needs by creating sample JSON documents and measuring their individual size.
Paid plans are allowed to store up to 110% data capacity. You will receive alerts at 95% capacity in order to give you time to upgrade your plan. The server may automatically block additional writes beyond 110% capacity.
