How to Sync Withholdwise Across Devices Using Your Own Cloud Storage

Why Portable Vault Sync Beats Cloud Accounts

Most financial web applications store your sensitive paystub data, SSNs, and salary figures on remote cloud databases. Withholdwise is built on a 100% on-device privacy architecture: your tax scenarios and paystub history live strictly inside your local browser storage.

To let you access your tax planning on your laptop, desktop, or tablet without sacrificing privacy, Withholdwise features Portable Vault — a secure sync mechanism using WebCrypto AES-GCM 256-bit encryption.

Step-by-Step: Syncing via Google Drive, Dropbox, or iCloud

• • Step 1: Open the Track tab in Withholdwise and locate the Portable Vault section.
• • Step 2: Enter a strong 12+ character vault password.
• • Step 3: Click "Save to Cloud Folder". Choose a location inside your local Google Drive, Dropbox, or iCloud folder.
• • Step 4: On your second device or browser, open Withholdwise, go to Portable Vault, enter your vault password, and click "Load from Cloud Folder".
• • Step 5: Select your synced file. Withholdwise decrypts the vault locally in your browser and restores your entire planning timeline.

Best Practices for Zero-Trust Cloud Storage Sync

Because Portable Vault encrypts your file before it ever touches your file system, you can safely store the backup file in any personal cloud storage folder (Google Drive, Dropbox, OneDrive, iCloud) or even an encrypted USB drive.

Store your vault password in a password manager (like 1Password, Bitwarden, or Apple Keychain). Withholdwise servers never receive your file or password, guaranteeing that only you have access to your financial data.
