Not a problem; here are the answers 1. No, you do not need to format your calendar in any special way. We've developed a machine learning algorithm that automatically figures out the correct phone number and PIN number (if available). It works in 99.98% of the cases. In those rare cases that it misses, Callr will ask the user for a feedback and adjusts the algorithm based on that input. 2. There are a couple of important points; Callr only looks at a few days worth of events at a time and we did that by design. This will ensure that Callr does not have more information than it actually needs. Once the data is pulled, Callr is built like a fortress; we encrypt it with AES-256 to make sure it's fully locked.
