myQNAPcloud is QNAP's family of cloud services for owners of QNAP NAS devices. It provides remote access to QNAP devices from phones and computers, plus cloud storage: myQNAPcloud Storage for backing up NAS data and as a cloud drive for documents, photos and videos, myQNAPcloud Object (S3-compatible object storage) and myQNAPcloud Surveillance for backing up surveillance recordings. The services are delivered as hosted cloud services connected to the QNAP NAS.
QNAP is headquartered in Taiwan (New Taipei City) and is a privately held company. According to QNAP, myQNAPcloud Storage runs in third-party data centres in regions across North America, Europe and Asia-Pacific. In Europe, QNAP lists Amsterdam, Frankfurt and Paris, plus a site in the United Kingdom (Slough). The software is not open source. A European region keeps stored data in Europe, but the provider is a non-European company, so check which region your data is placed in and what contractual terms apply.
