We only sync limited data/fields from Tally which we want to show it on the mobile app. So putting the data back might not give 100% result in Tally. Secondly, we do not have any database stored on the server through which the data can be pulled back. Thirdly, the key to decrypt the data is stored on the mobile device only and only at the mobile device, data can be viewed, thus making it not possible to reverse the data. Lastly, to provide another level of data security, we have decided not to provide this as a solution.
