If you tap to one of the transactions you can see:
Yes, Lumi is an HD (or "hierarchical deterministic") wallet. That means a new, unique address will be generated every time you send or receive funds, which makes your transactions harder to track, keeping your financial business yours. There’s no need to back up each address separately, all of them can always be restored using your wallet’s 12-word mnemonic phrase. All addresses generated from the same wallet can be used to receive funds, and all funds sent to any of these addresses will show up in your balance. The balance you see on your main wallet screens represent the total sum between those addresses.
The previous version Lumi Lite is not HD. While that's simpler, address reuse undermines your privacy. We recommend you to use Lumi HD.
In order to receive coins from any other address you should provide your public address to the sender. To do so, you need to tap the “receive” button.
There you will see a QR code which you can show to the sender if they have a QR scanner. Otherwise you can copy the address by tapping on it. You also can tap “share” to send your public address via other applications such as “Mail”, “WhatsApp”, and others.
You also can specify the exact amount that you want to receive by clicking “Add Amount” but it works only with a QR scanner.
To send BTC or ETH you can either directly open the QR code scanner or tap “Send” and paste an address where you would like to send your bitcoins. Pay a lot of attention to the correctness of the receiving address and never type it manually due to the high risk of making a mistake! Always double-check the address you are going to send bitcoins to because in case you send coins to the wrong address you will not be able to cancel the transaction or request a refund.
Then you click “Next”. You will arrive at the screen where you can specify the amount you would like to send. You can type the amount either in BTC/ETH or in USD (it will calculate the amount in BTC/ETH based on the current exchange rate).
The transaction fee is calculated automatically or you can customize it manually. We suggest that you select the recommended fee amount, as it is balanced by speed and cost.
At the first launch of the Lumi application you will be obliged to set a PIN code. We do so in order to protect your funds. We do not require any other registration, and the PIN code is the only way to protect your wallet from any unwelcome quests.
If you would like to change your PIN code you need to go to the sidebar and select “Change PIN”. Then you enter your current PIN and after the new PIN twice.
Yes, you can. You should switch on Touch/Face ID in sidebar.

Go to the sidebar Backup wallet. You will see 12 words one by one. Write a copy of each of these words carefully. Then you will be required to retype all 12 words in order to check the correctness of your backup. Store your copy of these 12 words (mnemonic) in a very safe and secure place and never give it to anyone you don’t want to have access to your funds.
Never switch your wallet without having a Backup. The only way to get access to your funds is with your 12-word Backup Phrase.
We ask that you write down your 12-word Backup Phrase in the exact sequence before you exit your wallet as your funds and private key are tied to your unique Backup Phrase. Your 12-word Backup Phrase allows you to restore your wallet and regain access to your funds at any time on any device that supports Lumi wallet. After switching the wallet, you will not have any other way to access your funds except the 12-word backup phrase.
In the unlikely event that Lumi, as a company, is no longer around, you may also use your 12-word phrase to transfer your existing funds in Lumi to a similar wallet service that utilizes the mnemonic system and has the same derivation path.

Every time you send transaction in Bitcoin or Ethereum network you need to pay the network fee. This fee goes to bitcoin miners who confirm your transaction.
The size of the fee depends on the transaction difficulty and network load. If there are a lot of transactions at a particular moment in time, miners take first more expensive transactions and cheaper ones goes to the further blocks.
Therefore, higher fees guarantee faster confirmation.
Lumi wallet provides you 4 options to choose from:
Lumi is a client-side wallet and if your transaction was sent to blockchain and you see it on block explorers it means that it is waiting for a confirmation and cannot be cancelled. How long a transaction can be pending?
Different transactions require different amounts of time. It depends on a fee. The higher fee the higher speed of transaction confirmation.
