All survey information as well as participant responses is backed up daily and archived for 90 days. This is in-line with iSolutions data retention policy and they reserve the right to reduce the retention period at any time.
Note that it is not possible to recover or restore data that you delete, so ALWAYS download a copy of your data before manually deleting participants’ data.
It should be noted that iSurvey data is only ever deleted by a survey editor i.e. you. Any data collected via iSurvey can be stored indefinitely on the server. However we highly recommend downloading your dataset as a CSV file for offline storage. This will give you peace of mind, but you can never have too many backups of your research data!
