+3.  **Backup and Recovery**
 
-   You can use the global backup function to back up data locally or via the cloud, including identity, Persona, encrypted social information, wallet (optional), etc. The user needs to set up a backup password to encrypt the selected data. If the user chooses to back up the local wallet, the user needs to enter the payment password to verify the wallet. When the user chooses to back up via cloud provided by Mask Network, the user needs to set up a mobile phone number or email address for sending and receiving verification codes so that the encrypted backup data can be fetched from cloud.

-   Blockchain contract interactions refers to asset transferring, receiving, red packets, Swap, ITO, etc. You can use Mask Network's services such as transfer, receiving, red packets and Swap to manage digital assets, that is, use private keys for electronic signatures and to modify related blockchain ledger. Transfer means that the payer uses the payee's blockchain address to conduct transfer operations. The actual transfer and receiving operations occur in the relevant blockchain systems (not Mask Network).

For DApps provided by third-party platforms, Mask Network only provides users with access to the DApp and provides a blockchain browser, and users can click it to jump to the third-party DApp and use the services provided by the DApp. As Mask Network provides non-commercial integration services, it will integrate plug-ins provided by community members and excellent teams of third-party DApps. Before using any wallet-related plug-ins in Mask Network (including Mask Network’s own DApps and third-party DApps), the users need to confirm the risk warning.

-8. **File Storage Service**
+8.  **File Storage Service**
 
-   The file storage system currently used by Mask Network is Arweave's permanent storage system by charge. We do not rule out the possibility that in the future users may need to pay for file storage by themselves. Arweave's file storage can only be encrypted and stored by user's own account. Mask Network cannot parse any user’s encrypted files. The files can only be decrypted by users of Mask Network themselves. As the file storage service is provided by Arweave, Mask Network shall not be liable or responsible for any file problems that might occur.
+    Mask Network currently supports multiple file storage systems, including Arweave, IPFS, and Load Network.
 
-9. **Service of Suspension**
+    By default, files are stored using Arweave’s paid permanent storage system. In the future, users may be required to cover storage costs themselves.
 
-   You understand and agree that based on the "irrevocable" nature of blockchain system transactions, we cannot suspend or cancel transactions for you.
+    Within these file systems, files can be uploaded either with or without encryption, using the user’s own account.
+    Mask Network cannot access any encrypted files, and only the user who encrypted the file can decrypt and access it.
+
+    Please note that file storage services are provided by Arweave, IPFS, or Load Network. Mask Network assumes no liability or responsibility for any file-related issues arising from these services.
