Offline Invoice Maker
Effective October 21, 2026. This policy describes the Windows desktop app published by Compile North. Contact [email protected] with privacy questions.
Data the app uses
The app stores the business name, address, email, phone and currency you type, plus each invoice: client name, address and email, dates, invoice number, line descriptions, quantities, prices, tax, notes, paid status and whether a logo file was used. If you choose a logo, the app reads that image file only to draw it on the PDF.
Where processing and storage happen
Invoices are saved on your Windows device at %LOCALAPPDATA%\CompileNorth\OfflineInvoiceMaker\ledger.json. PDF files are written only to the folder you choose. The app does not upload invoices to Compile North, use advertising, or send app analytics. It does not maintain a Compile North account or a remote copy of your invoices. Files, folders, Windows backups, sync software and other apps on your computer remain under your control.
Microsoft Store purchases
If the one-time Pro offer is available, Microsoft Store handles checkout, account details, billing and refunds. The app asks Microsoft Store whether that add-on is owned so it can unlock Pro features and show the Store price. Compile North does not receive your payment card details through the app. Microsoft processes Store account and purchase data under its own privacy terms.
Sharing, security and your choices
The app does not send your invoices to Compile North or to anyone else. You choose what to type, where to save the PDF, and whether to share or delete it. Deleting an invoice removes it from the local file. A PDF you already saved is not deleted by the app. Review each PDF before you send it to a client.
Support requests
If you email support, we receive the information you choose to send, such as your email address, message and attachments. Do not send invoices that contain client details unless support specifically requests them and you agree. We use support messages to answer your request and do not need your invoices for normal app operation.
