Terms of Service And Privacy Policy (last updated: 13 April 2025)

This is a contract (the “Agreement”) between you and Cypher Box LLC (“Cypher Box” “we” or “us”), a company registered and incorporated under the laws of Delaware whose registered office is 8 The Green, Suite B. Dover, Delaware 19901, USA. References in this Agreement to “you” and “your” are to the person with whom Cypher Box enters into this Agreement. By checking the box, clicking on “Start”, “I understand”, “next” or similar terms when you open the application and go through the instructions and warnings with regards to using our integrated third-party APIs, and Vaults, (all referred to as ‘Services’) or by proceeding with a download or update when offered a choice of proceeding or not, you are agreeing to be bound by the terms and conditions found in this Agreement. You represent and warrant that you have the power and capacity to enter into this Agreement.

1. Third-party Custodian Lightning Account(s)

Cypher Box lets you connect through API(s) (create account and/or login) to one or more Bitcoin custodians that (if benevolent) allows you to request sending and receiving payments quickly and cheaply in Bitcoin (BTC) through their Lightning Network infrastructure. A custodian is an entity that allows you to transact and accumulate bitcoin (up to a certain subjective threshold) quickly and cheaply depending on your jurisdiction. The funds stored on your custodian ‘Lightning Account(s)’ are technically under the full control of the custodian, NOT OURS, NOT YOURS. The balance shown on your Lightning Account(s) may or may not be real Bitcoin. Despite our efforts in choosing the most trusted and regulated Bitcoin custodians, we can never be certain that when you use the ‘Receive’, ‘Send’, ‘Top-up’, or ‘Withdraw’ functions the custodian(s) will credit/debit your Lightning Account(s) balance(s) if you receive/send bitcoin from/to another user or from/to your vault with the fees they advertise, or if they will uphold their promise in keeping their internal ledger matched one to one with their bitcoin reserves. Moreover, while we carefully selected our custodians for reliability, we cannot guarantee a 24/7 uptime or that your particular transactions will be processed by them. Custodians might face liquidity issues or other technical problems that can only be solved on their side, NOT OURS. A Bitcoin custodian, just like a regular bank or exchange, can seize, freeze, or steal the balance displayed in your Lightning Account. Custodians can even sometimes get hacked. Cypher Box LLC is not liable for any funds stolen by the custodian(s) we integrate with. If you face any problems in Lightning Account(s) you should first login to your Custodian’s website or mobile application and validate your balance and transaction history from their side. Cypher Box is not liable for any error that occurs within the custodian(s)’s ledger(s) or in the transfer of requests and callbacks through their API. Due to all the uncertainties mentioned above; we highly recommend that you read and follow the instructions, assess the reputation and trustworthiness of the custodian and only store a measured amount of bitcoin inside your Lightning Account. You may use multiple custodian Lightning Accounts outside the app to spread the counter-party risk, periodically monitor your Lightning Accounts’ balances and activities from the custodian(s) website or application, and once you’re knowledgeable enough to understand self-custody and the risks associated with holding your own keys, withdraw your bitcoin into one of your Vaults preferably when your balance reaches the threshold where it makes economic sense to pay for Bitcoin Network fees and demand real ownership over your funds.

2. Crypto Exchanges

Some custodians in Cypher Box may give you the option to buy or sell ‘bitcoin’ for fiat currency depending on your jurisdiction. These regulated exchanges may also run their own lightning infrastructure so they may also allow you to transact in bitcoin quickly and cheaply. However, all the risks, uncertainties, and guidelines mentioned above with regular bitcoin custodians also apply to cryptocurrency exchanges.

Cypher Box LLC is also not liable for any financial losses due to a failure or error in executing any trade happening between you and a cryptocurrency exchange we have in our app.

3. Self-custodial Vault(s)

Cypher Box enables you to create single, hierarchical deterministic (HD), non-custodial wallet(s) (referred to as ‘Vault(s)’) for Bitcoin. You can use these vaults to withdraw from your Lightning Account(s), store, send, and receive the digital asset Bitcoin only (BTC). In order to use the hot or cold storage Vault(s) you are expected to be fully aware of the dangers associated with securing your 12-word backup seedphrase. You are expected to know that; you should never lose access to your seedphrase(s), you should write the words in their correct order on a physical medium such as a paper or a metallic plate, you should make multiple physical copies of them and store the copies in secure locations, you should never share them with anyone including us, and you should never ask us to recover your Vault(s) funds because the only entity capable of doing so is the one that holds the private keys represented in the form of a 12-word seedphrase which is YOU, NOT US. These Vaults are intended for use by persons who are very knowledgeable about cryptocurrency generally and HD non-custodial wallets in particular. If you read our instructions and warnings carefully and understand the risks associated with self-custody, you represent that you qualify as such a person.

4. Supported Digital Assets

Our Services are for use with Bitcoin (BTC) only and any other digital assets we may explicitly decide to support in the future at our discretion (“Digital Assets”). We have no obligation to support any digital assets (including but not limited to any forkcoins, altcoins, airdrops or any other digital assets however named) other than Bitcoin or any other digital asset we may explicitly decide to support in the future at our discretion. We assume no responsibility or liability in connection with any attempt to use your Vault for digital assets that we do not support.

5. Responsibility for Lightning Account(s) Credentials, Vault(s) Backup Seedphrases, Passwords and Other Authentication Means

Our Services provide a number of ways for you to secure your funds and help ensure you, and only you, are able to access and transact through Lightning Accounts and Vaults. These features include API authentication tokens, backup seedphrases, passwords, biometrics, among other features.

6. Mnemonics and Catastrophic Impact of Their Loss or Misappropriation

If you use our Services to create a Vault, the software will use an algorithm to generate a random 12-word phrase as a seed to a BIP39 hierarchical wallet. This 12-word phrase is called a backup seedphrase and if reproduced exactly stores all the information needed to recover your Vault(s) if access through the App or phone Password, face-ID or other authentication means is lost or otherwise not available. Cypher Box LLC does not store, have access to, or have any way or means of recovering your backup seedphrase. It is your responsibility to keep your seedphrase secure. You should not provide it to anyone, including any Cypher Box LLC representative.If you permanently forget or lose your backup seedphrase, you will NEVER be able to recover any cryptocurrency in your Vault, and you will suffer a complete, irrecoverable and catastrophic loss of all Digital Assets in your Vault. It is your responsibility to safeguard and retain your backup seedphrase. Cypher Box has no responsibility and will not be liable for any loss or damage you suffer from the loss or misappropriation of your seedphrases.

Cypher Box LLC has no responsibility and will not be liable for any loss or damage you suffer from the loss of access to or use of your Vault(s) during any termination of our Services.
