No. Captures are held on your device and sync as soon as you are back online. This matters more than it sounds: a hall with twenty thousand people in it is one of the worst mobile environments there is, and the moment you need capture to work is the moment everyone around you is also on their phone.
What still works with no signal
What waits for the connection
The parts that need a server: extracting the fields, drafting the email, and sending it. Those resume on their own once you are online — in the taxi, at the hotel, or in the corner of the hall where the signal happens to work.
Because emails are sent in a paced queue rather than all at once, a backlog that syncs at six o'clock does not go out as one suspicious burst.
Unlimited leads free, no card. Try it in the worst corner of the hall.
