❓ Getting Started

PetalVault is a secure offline password manager with AES256 + Scrypt encryption, mnemonic phrase as the primary key, and offline synchronization using QR codes

PetalVault allows you to create multiple vaults on one device, each protected by different keys. For example, multiple people can use one device, or you can use separate vaults for different tasks

Each vault is securely encrypted with a master key derived from mnemonic phrase (12 words). You can scan or show this phrase using a QR code. Additionally, to simplify access to the vault, you can create your own master password. In this case, the mnemonic phrase will be encrypted with this password and stored in the vault. If you forget the master password, you can restore access to the vault by entering the mnemonic phrase

Each vault can be exported and imported using QR codes. You can also set up synchronization between two devices to sync only changes, not the entire vault. Synchronization can be performed in public places, as the data in QR codes is securely encrypted. Note that both devices must have the same mnemonic phrase since the synchronization key is also derived from it

📦 Download and Installation

• To download .apk or .aab file, go to the link https://github.com/F33RNI/PetalVault-Android/releases/latest and download the file for your device
• Alternatively, you can build the app yourself. For this, refer to the 🏗️ Building from Source section

🆕 Creating or Importing a Vault

1. First, create or import a vault. To do this, click on the + New or ↓ Import button
2. Choose any name for your vault. You can rename it later
3. Create a mnemonic phrase or choose a randomly generated one. Write this phrase down in a secure place because if you lose the master password, you can only restore access to the vault using this mnemonic phrase.
   • For import, scan the QR code of the mnemonic phrase from another device. Keep in mind that the phrase is in plain text, so during the scanning, no one should see the QR code
4. Choose whether you want to save the mnemonic phrase encrypted with your master password. If your password is strong you can safely use the master password.
5. Enter the master password twice. If they do not match, you will be prompted to enter it again
6. Wait for the vault to be created. On weaker devices, this might not happen instantly
7. For import, scan all QR codes from another device in sequence, after selecting export

🔐 Adding Entries

1. To add entries, click +. You have 4 fields available: website address (or name for which the password is used), username, password, and notes. The data in all fields are encrypted, so you can store sensitive data in any of them
   • To add an entry, you must fill in the site and/or username fields. PetalVault also automatically generates a strong password that you can use for this entry
   • All 4 fields have a copy to clipboard function. To do this, click the button to the left of the field
   • The password field is hidden by default. To show the text, click the 👁️ button on the right
2. Confirm by clicking the ✔️ Done button

✏️ Editing and Deleting Entries

• To edit and copy data of each entry, click on the text in the list. You can change any field
• To delete an entry, click on the 🗑️ button at the top of the editing dialog and confirm the deletion

🔄 Synchronization and Export

1. Click the Sync button and select Sync to. Choose an existing device or create a new one. This is necessary to sync only the changes in the future, not the entire vault
2. On the other device, select Sync from and scan the QR codes
3. If the mnemonic phrases do not match (the master password, unlike the mnemonic phrase, can differ), an error will occur because the synchronization data is encrypted
4. During the first synchronization, especially if there are many entries, there may be several QR codes. Scan them all sequentially. If you missed a QR code, you can scan it later, as the order of scanning does not matter

• To export the vault to a new device (without creating a device), click the Sync button and select Export. On the other device, click Import / Sync from and scan all the QR codes

⚠️ For synchronization/import/export, the mnemonic phrase on both devices must be the same. However, the master password, unlike the mnemonic phrase, can differ

📝 Editing and Deleting the Vault

• You can rename the vault. To do this, click the ✏️ button at the top of the dialog and enter a new name
• To delete the vault, click the 🗑️ button at the top of the dialog and confirm the deletion

⚠️ For security reasons, the vault can only be deleted after it is decrypted
