Invoice documents stay on your device
Vault Mail reads supported files in your browser. The invoice comparison does not upload PDF files, extracted invoice text, or entered comparison details to our server or an AI service. The PDF reader is served with the website, rather than loaded from a third-party content delivery network.
Original invoice files are not copied into My vault. A saved record contains the entered fields, comparison result, and date. It is stored in this browser on this device.
Local storage and backups
We use local browser storage for your comparison allowance and saved records. These records are not automatically synchronized between devices. You can delete individual records, clear your saved vault, or download and restore a backup.
Local records and downloaded JSON or CSV files are not encrypted by Vault Mail. Someone with access to your unlocked browser or backup file may be able to read them. Use your device's access controls and keep backups in a private location. Clearing website data, browser storage eviction, or device loss can remove locally saved records.
Ordinary website requests
Your browser requests website pages, scripts, and images from our hosting provider. Like other hosting providers, it may process network information such as IP addresses and request details to deliver and protect the service. This is separate from invoice processing.
This version of Vault Mail does not include advertising trackers or third-party analytics. Opening an external link is subject to the destination's privacy practices.
When you contact us
If you submit the contact form, your name, email address, selected subject, and message are sent through Web3Forms to our contact inbox so we can respond. Do not include confidential invoice contents, passwords, or bank account details. The form does not attach your comparison files or vault records.
Contact correspondence may remain in our inbox while we handle the request and maintain the necessary conversation record. Contact us to request deletion of correspondence. See Web3Forms' privacy policy for its processing practices.
Purchases and Pro activation
Gumroad handles checkout, payment information, receipts and memberships. As the seller, we can access purchase and subscription information made available by Gumroad. We do not receive your payment card number through this website. See Gumroad’s privacy policy for its processing practices.
When you activate Pro, your browser sends the license key and our product identifier directly to Gumroad over HTTPS. The browser checks the returned purchase and membership status. Invoice files, extracted text, entered invoice fields and saved vault records are never included in this request. The website does not store the returned purchase details in a separate database.
Your license key is kept in local browser storage to check Pro access when you return. Checks also happen periodically while you compare. The key is not encrypted by Vault Mail: keep access to your browser private. Remove it on the Activate Pro page or clear website data. Removing the key does not cancel your subscription. Contact messages about billing may remain in our support inbox.
Questions and data requests
Email contact@vaultmail.app. We cannot recover, view, or delete invoice records stored only on your device; use the controls in My vault for those records.
