4.          The Mailchain Platform And Becoming An Account Holder On The Mailchain Platform

 

4.1       The Mailchain Platform. The Mailchain Platform offers several services, the details of which are set out on the Mailchain Platform and in the Terms. To fully enjoy the services available on the Mailchain Platform you may be required to register as an Account Holder. Subject to compliance with the Terms, you are granted, during the term of this Agreement, a non-transferable, non-exclusive, non-sublicensable license to use the Mailchain Platform. You understand that your use of the Mailchain Platform and the Services does not confer on you any Intellectual Property Rights held by Mailchain and/or its licensors. You are merely given a license to use the Mailchain Platform provided by Mailchain, in accordance with the Terms.

 

4.2       Who can use the Mailchain Platform. To access all the features of the Mailchain Platform, you may be required to register as an Account Holder. To register as an Account Holder, you must:

 

(a)   be over 13 years of age;

(b)   complete any verification processes that we require; and

(c)   ensure that you have all relevant rights, licenses and/or approvals in relation to any blockchain addresses that you register on the Mailchain Platform.

 

4.3       Provided on an “as is” basis. The Mailchain Platform is provided on an “as is” basis and we disclaim to the fullest extent permitted by law all warranties, express or implied, statutory or otherwise. Specifically, we make no representations, warranties or guarantees about the accuracy, reliability, completeness, correctness or timeliness of the Mailchain Platform or communications provided on or through the use of the Mailchain Platform.

 

4.4       Availability of the Mailchain Platform. Access to the Mailchain Platform is provided on a temporary basis. We may discontinue or make changes to the Mailchain Platform at any time. We do not guarantee that the Mailchain Platform will be available at all times and on an uninterrupted basis and we will not be liable to any User or Account Holder for any Costs that they suffer or incur as a result of the Mailchain Platform being unavailable at any time or for any period. 

 

4.5       Account registration. You can create a Mailchain account using a private key that you own. This private key derives a set of public/private key pairs responsible for different protocol functions. These key pairs include an identity key, a root messaging key, and any number of other keys for account level functions. When you create a Mailchain account, an identity key is derived. The identity key acts as the principal identity for a Mailchain account holder. Optionally, an account username (e.g. firstname@mailchain.com) can be registered with the identity key and stored in our registry. This binds the username to the identity key so messages can be sent and received using the username. You can register an external identity or blockchain wallet address with Mailchain to receive messages sent to that external address. For each address, the root messaging key derives a child messaging key. A “proof” is generated, verifying this ownership. The proof contains the details of the corresponding “messaging key”. Proofs are stored in the Mailchain registry.

 

4.6       Account Level Functions. A Mailchain account has a set of keys for account-level functions, including identification, signing, and encrypting mailbox data. These functions run independently of the protocol, giving you full autonomy over your data and identity without relying on the protocol, Mailchain or any other party.

 

4.7       Identity key. When you register for an account on the Mailchain Platform, you will be issued with an “identity” key. You should safely store a record of this identity’s “secret recovery phrase” and your Account password. You are solely responsible for maintaining the confidentiality and safety of your Account, password and secret recovery phrase, and for restricting access to your computer or any device on which you use the Mailchain Platform. Your account is intended for your sole use. You agree to accept responsibility for all activities that occur under your account. If you have reason to believe that your account is no longer secure (for example, in the event or loss, theft or unauthorised disclosure) we recommend that you notify us and take steps to protect your registered accounts and data. You may be liable for the Costs incurred by us or others due to any unauthorised use of your account. Mailchain will, under no circumstances, be liable for any loss or damage arising from your failure to keep your account secure. 

 

4.8       Secret Recovery Phrases and Private Keys. If you lose your secret recovery phrase for your identity and your password, you will need to follow the steps on our support site to re-register on the Mailchain Platform with a new identity. A secret recovery phrase is a readable form of a private key. In this clause 4.8, we use the term “private key” to mean either secret recovery phrase or private key. We will never ask you to input your Mailchain private key unless you are attempting to recover your account. In this case, the unencrypted private key does not leave your device at any time, and we cannot ever read it. Likewise, we will never ask you to enter any private key related to another blockchain address or wallet that is not a Mailchain identity key. Please report any attempts to access your private key by sending a Mailchain message to phishing@mailchain or an email to phishing@mailchain.com.

 

4.9       Address Registration and Messaging Keys. If you register a blockchain address with Mailchain to receive messages in your inbox, you will “sign” a piece of data using your blockchain wallet to produce a “proof”. This proof is used when sending you messages and is publicly verifiable by anyone. It cannot be directly linked to your identity. If the blockchain address is re-registered to another Mailchain account, your account will stop receiving messages.

 

4.10    How you will use the Website and the Mailchain Platform. When using the Mailchain Platform, you agree that you will:

 

(a)   comply with the Terms at all times;
