Your cards stay in your browser
Updated September 24, 2026.
Entries, drafts and saved cards
The card builder processes your entries in your browser. Working drafts and preferences use session storage; named saved cards use local storage. The application does not upload rifle names, loads, notes, card entries or editable backups to our server. Changing browsers or clearing site data can remove access to stored work.
Downloads and backups
Filled PDFs and editable JSON backups are generated on your device. Keep backups somewhere you control. Anyone with a backup file can read the entries inside it; choose deliberately before sharing one. Import is processed locally and does not upload the file. Large libraries may require several backup parts.
Website delivery
Cloudflare hosts the site and processes network requests to deliver it and protect its services. Requests include information such as IP address, requested URL, browser information and time. That network activity is distinct from card entries, which the builder keeps local. We do not use advertising pixels. Optional Google Analytics is described below.
Optional download analytics
Google Analytics loads only after you select Allow analytics. It uses analytics cookies and processes technical information about your visit to report website use and download requests. Advertising storage, advertising personalization and Google signals are disabled in our tag configuration. We send only the card format, download source (blank template, builder, saved card, batch or fit pack), paper size and number of requested cards, alongside a cleaned page address. We do not send card entries, rifle/load names, saved-card names, imported tables, backups, or generated PDF contents. Page query strings, fragments and referrer details are excluded from our analytics events.
A download event means a blank-file link was selected or a PDF was prepared and its download requested; it does not prove saving or physical printing. Offline use, declined consent and blocked analytics are not counted. We do not queue offline activity for later upload. Direct PDF visits outside our pages may not be counted.
Select Analytics settings in the footer to change your choice. No thanks stops measurement and removes accessible Google Analytics cookies for this site. Your choice is stored locally for up to 180 days; clearing browser storage removes it. We also keep analytics off when the browser supplies Global Privacy Control or Do Not Track. Card storage remains separate and is not affected by analytics choices. Google handles analytics data under its Privacy Policy.
Email feedback
The feedback form opens your email app with a draft. Nothing is emailed until you send it. If you contact us, your email provider and our email provider process your message, and we use what you send to respond and improve the site. Do not include information you do not want to share.
Choices and questions
You can delete named saved cards in the library or clear this site's data through your browser. Export an editable backup first if you want to keep your work. For privacy questions or requests concerning email you have sent, contact Preston@WillisInnovations.com.
