Hi @95.omega
Yes, as a user you need to give odrive access / permissions to the storage, authorizing a linked storage source allows us to send it requests on your behalf, triggered by your actions. When you utilize the odrive desktop client it then can make requests directly to the storage sources you are linked to.
We don’t store any of your data in our servers, communication and transfers to those sources are direct between the odrive desktop client (your computer) and the storage.
Thanks,
Asif
