Each device that is bought back through Reebelo must undergo a full data wipe. Reebelo's partners are professional refurbishers registered with the Singapore Police Force who must respect PDPA and user privacy regulations. In any case, we always advise you to firstly backup, and then delete all data and remove all accounts from your device before selling it. Please note that once sold, we will not be able to retrieve any data that you have forgotten to backup.
