Contingency Zero: My Emergency Preparedness App If something happened to you today, would your loved ones know how to access your important information? Contingency Zero gives you and your family peace of mind by solving one of life's most overlooked challenges. THE PROBLEM WE SOLVE In today's unpredictable world, unexpected events can strike without warning. When the unthinkable happens, families are often left dealing with emotional trauma while facing the overwhelming task of piecing together financial and legal information. Most people understand the importance of having a plan, yet few take action until it's too late. Traditional estate planning methods are often cumbersome, outdated, and fail to address the digital nature of our modern lives. A SECURE SOLUTION FOR MODERN ESTATE PLANNING Contingency Zero transforms how you prepare for life's uncertainties through a secure estate planning platform built with privacy at its core. Our innovative zero-knowledge system ensures your sensitive information remains private while allowing you to share access with designated trusted contacts. KEY FEATURES + Privacy & Security First Your information is protected with end-to-end encryption, ensuring only you and your designated contacts can access your data. Our zero-knowledge security architecture means that even we cannot see your private information. + Organize Your Life into Binders “Cars”, “Pets”, “Bank accounts” are some of your important assets. If something happened to you, you would like your survivors to know what they are, where they are, and what to do with them. We help you organize them into “Binders”. You can have as many binders as you want. Each binder has a name, a description, and a fixed binder type. For example, you could create two auto binders, one named “My Texas cars” and one named “My Florida cars”. You can even set a different icon to each binder. Binders help you organize your assets in a way that makes sense to you. + Flexible Sharing Options Share your complete estate plan or only selected binders with trusted contacts. Choose exactly what to share and keep the rest private. You can also enable automatic sharing so that newly added binders are shared with your trusted contacts without extra steps. + Control Access Permissions Decide how much control your trusted contacts have: Read Only – They can view your shared binders but cannot make changes. Full Access – They can add, edit, and delete binders and binder entries. Your information, your rules — share with confidence. + Detailed Version History Our version control system lets you update your information while maintaining a history of previous versions, ensuring nothing important is ever lost. + Intuitive User Experience The app guides you through the estate planning process step by step, making a complex task manageable through a clean interface. HOW IT WORKS Getting started with Contingency Zero is simple. Download the app and create your estate plan. The guided setup helps you organize information into the four binder categories.

You're not sitting at a desk with a filing cabinet. You're on job sites, in client properties, running between appointments, buying materials on the fly. Every tax receipt matters. Every mile is a deduction you've earned. PaperTrail makes sure none of it slips through. Thermal receipts fade. Paper gets lost in the truck, the wash, or the junk drawer. Miles go unlogged because you forgot by the time you got home. PaperTrail captures everything the moment it happens — and keeps it searchable, backed up, and ready when your accountant needs it. Whether you're a contractor tracking job expenses across multiple projects, a gig worker separating business from personal, a freelancer managing 1099 income and deductions, or a real estate agent logging trip after trip between showings — PaperTrail handles the recordkeeping so you can focus on the work. No spreadsheets. No shoeboxes. No scrambling in April trying to reconstruct six months of business expenses from memory. Just a clean, organized expense journal that's always current, always backed up, and always ready. Your deductions are worth real money. The average self-employed worker leaves thousands on the table every year simply because they didn't track it. PaperTrail makes it effortless to capture every receipt and every mile — so when tax time comes, you hand your accountant a complete record instead of a pile of guesses. Download PaperTrail free. Every receipt. Every mile. Every deduction. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
