Seedvault allows Android users to store their phone data without relying on proprietary cloud storage, with options ranging from a USB flash drive to a remote self-hosted cloud storage alternative such as Nextcloud. The use of Nextcloud logo by Seedvault is meant to refer to Nextcloud servers users can connect to and perform their backups. Seedvault is not a Nextcloud partner and is not affiliated with Nextcloud GmbH.
