Such data, including the file content and file name, uploaded by You are completely encrypted at Your endpoint before being stored onto our platform. However, there are two cases where the C2 server decrypts and temporarily accesses the file: (a) When You apply dynamic watermark with the receiver's information to the transferred document, the C2 server will decrypt and temporarily access the document. The receiver's phone number and/or email address will be used for applying the dynamic watermark that demonstrates the receiver's information, or be hashed and used for one-time-password (OTP) verification, and will be stored on our platform until the transfer task is removed from Your account; and (b) When Your Content from Your Storage Space is transferred with watermark, the C2 server will decrypt and temporarily access the document to apply the watermark. In order to provide log records, IP addresses of Users (as defined in C2 Terms of Service) will also be collected by our server. Other usage information generated by using the C2 Transfer service, such as link expiration time, file size and other unidentifiable information, will not be encrypted and are collected and used for the sole purpose of improving the service experience and adding new features.

How we use your data

Synology only uses data you provide to us to offer you the C2 service that you order from us. We do not access or analyze the data you upload, except that, as stated above, for the cloud service backup, we will access part of Your Content to provide service and search feature. Apart from C2 Backup, other C2 services will not access the data you upload. To provide service stability and optimize user experience, Synology may analyze non-personal identifiable service usage information that cannot be used to identify you or your device.

How we store your data

Synology maintains your files in the Unites States, Germany, or Taiwan depending on your choice. Synology C2 services support full encryption of your files. Your data is protected with industry-standard encryption practices. Your files will never be accessed by our engineers unless a specific technical support request is made by you and requires us to do so. You can delete your data anytime during the subscription period. If your subscription ends, all your data will be deleted after a "grace period" defined by the Synology C2 Terms of Service. If you choose to delete your Synology Account, your data and subscription status for Synology C2 will also be forfeited and removed.

Synology AI Advisor

Data we collect

Synology AI Advisor is an interactive feature available on our website that enables users to engage in AI-powered conversations for assistance, guidance, and support. When using this feature, your chat conversations and feedback (such as thumbs up or thumbs down on AI responses) are collected and stored in an anonymous manner. This data is used to maintain continuity in ongoing conversations and to help improve the quality and accuracy of AI responses.

Conversations are stored exactly as entered. We strongly recommend that users do not share any personal information during their interaction with the AI Advisor.

Chat data and feedback are not linked to your Synology Account or any other identifying information. Instead, a randomly generated session ID is used solely to determine whether a conversation is new or ongoing.

How we use your data

The collected data is used to provide relevant AI responses, preserve conversation context, and assess the quality of the AI through user feedback. Synology may use this data to improve the AI Advisor experience and underlying models.

To enhance functionality, Synology may transmit conversation data to Microsoft Azure and utilize its OpenAI services. Access to conversation and feedback data is strictly limited to authorized personnel and is used only for maintaining and improving the AI Advisor feature.

How we store your data

Conversation logs and user feedback are stored securely on Synology servers and identified only by session ID. They are not associated with your Synology Account or any personally identifiable data from our systems.

Users may request deletion of their AI Advisor conversation data by providing their session ID. Upon verification, all data associated with that session will be permanently removed.

Session data may be retained for up to one year to support continuity and service improvement. Conversation data used for system training or evaluation is stored in a format that cannot be linked back to specific users.
