These terms aim to outline the specific matters that users (hereinafter referred to as "User") must understand and adhere to when using the MYKEEPiN service (hereinafter referred to as the "Service") provided by Coinplug Inc. (hereinafter referred to as the "Company").

MYKEEPiN
A DID-based digital signature (authentication) service designed to allow users to securely manage their personal information using self-sovereign identity technology.

DID(Decentralized IDentifier)
A technology used to protect personal information by providing an ID. The DID displayed in MYKEEPiN is a unique anonymous ID issued through the Metadium blockchain and is commonly referred to as META ID.

Authentication Means
The tools defined by the issuing institution to issue certificates. Users can choose the authentication means they deem necessary to obtain the certificate. Before proceeding with identity verification, the issuing institution must inform users about how their personal information will be used and obtain their consent. The Company bears no responsibility for this.

Certificate
MYKEEPiN certificates can be obtained by users once they verify their identity through an issuing institution. The information contained in the issued certificates is used as a means of transmitting the requested information to services associated with the Company.

Issuing Institutions
MYKEEPiN forms a DID ecosystem with partners, including issuing institutions and connected services. Issuing institutions perform the role of certifying information for certificate issuance. Before this, each issuing institution must inform users about the use of their personal information and obtain consent. The Company is not responsible for this process.

Connected Services
MYKEEPiN forms a DID ecosystem with issuing institutions and partner services. Connected services refer to companies that apply MYKEEPiN’s DID solution in their services. These connected services can request necessary information from users via MYKEEPiN, and once the user approves the request, the connected service can acquire the requested information. The responsibility for collecting, storing, and utilizing this information lies with the connected service, and the Company bears no responsibility for these actions.

Approval Means
Password input or biometric authentication methods provided to approve actions. The password is mandatory, and users must set a 6-digit number. Biometric authentication is an optional feature provided for convenience, and its availability may vary depending on the device and OS.

Information Management
All personal information, including the user's DID and certificates, generated through the services provided by the Company, is stored locally on the user's device. The Company does not store, manage, or access this information in any centralized system.

The user's DID, certificate, and all personal information are stored only on the user's device, and the Company does not have any administrative authority over them. Partners may request necessary information from users via MYKEEPiN services, and users can decide whether to provide the requested information using their approval means.

Backup and Recovery
Backup refers to the process of storing data such as certificates, authentication logs, and wallets to prevent loss when the MYKEEPiN app is deleted or the device is changed. The backup feature can be accessed during the first entry into the wallet or through the settings, and it requires email verification for backup and registration of a backup password.

Recovery refers to restoring previously backed-up data, including certificates, authentication logs, and wallets. To use the recovery function, users must verify via the backup email and enter the registered password. Only one backup file can be stored per email, and for security reasons, the backup password cannot be retrieved.

MY Wallet
The wallet feature of the service supports deposits, withdrawals, and storage of the virtual asset META. META (Metadium) is a virtual asset traded on major cryptocurrency exchanges such as Upbit, Bithumb, Bittrex, and KuCoin.

Deposit and Withdrawal
The user must be aware of the following when depositing or withdrawing virtual assets.

[Deposit]
Only Meta-based NFTs and META coins can be deposited to the displayed address in the Deposit menu. Deposit time may vary depending on blockchain network congestion. If the address has been inactive for a long period, it may be changed due to software updates or changes in the address system.

[Withdrawal]
Withdrawals can only be made to META wallets. Withdrawals are irreversible once initiated. When withdrawing to contract addresses, there is a risk of failure, so it is recommended not to withdraw to contract addresses. When using saved withdrawal addresses, check whether the address has changed due to software updates or address system changes.

Once deposit or withdrawal is completed, it will be reflected in the wallet balance and available for review in the transaction history.

MY NFT
MYKEEPiN’s MY NFT manages and stores Meta-based NFTs. These NFTs stored in MY NFT can be traded on METAPiE.

Company’s Obligations
