As long as you have access to the Pintu app on the same smartphone, all of your assets will be secure even if you lose your cloud backup.
If you lose your cloud backup (files in the cloud are deleted) but still have access to the same cloud service and smartphone, Pintu will create a new backup copy of the files to ensure the safety of your assets. You can do this by visiting Pintu Web3 on the Pintu app and following the instructions.
In the Beta version, you can recover your wallet using the same smartphone system (Android or iOS) that you used when backing up your files. Therefore, make sure not to delete backup files on cloud services and avoid losing your smartphone.
