Your privacy.

Your PDFs stay in your browser.

The preview reads and renders your PDF on your device. The application does not upload it to OffToPost, a mailing provider, or an AI service. The file is held in memory while you use the sending flow, and is cleared from that flow when you leave it or close the page. If you open the original PDF in a separate browser tab, close that tab when you are finished; leaving the sending flow does not close it for you.

Your addresses and email are temporary.

Recipient and return addresses and the email you enter are used to display your preview. They are not saved to browser storage or submitted to a server in this version. We recommend using the sample addresses while exploring.

A small amount of demo data stays in this tab.

When you create a demo order, session storage holds an anonymous reference, page count, illustrative price, and creation time. It does not contain your name, addresses, email, filename, or document. Up to ten demo orders are kept, generally until you close the tab. Browser session restoration may preserve them. You can remove them here.

No advertising cookies or analytics scripts.

This application does not install advertising cookies or third-party analytics. Fonts are served with the website. The hosting provider may process connection information, such as IP addresses and request logs, to serve and protect the site. URLs and anonymous demo references may appear in browser history or hosting logs.

Before real mailing begins.

A live service will need to share documents and addresses with a print-and-mail provider and use a payment processor. The operating business, contact details, providers, retention periods, and privacy rights process must be specified in an updated policy before accepting live orders. This notice describes only the current preview.
