Phone batteries die. ZeroPercent makes sure that's never the moment you can't reach your people. When a phone runs out of battery, gets lost, or is stolen, its owner can borrow a phone from someone they trust (a teacher, shop or station staff, a friend) and open zeropercentapp.com in the browser. They sign in with three things they already know: their own number, their date of birth, and a 6-digit Zero PIN. Their people are right there, ready to reach. Nothing to install, and they sign out before handing the phone back. YOUR PEOPLE, IN ONE PLACE • On your plan: your family or Duo, using ZeroPercent together • Backup contacts: anyone else you'd want to reach, like grandparents, friends or a coach. They don't need the app, and they confirm once on our website HOW FAMILIES USE IT • The adults who run the plan see everyone's battery at a glance, and get a heads-up when a phone is about to go dark • Teens join with an invite code, and an adult who runs the plan approves them • Couples, housemates and solo adults use it too. Everyone has people they'd need to reach when their phone dies WHAT ZEROPERCENT DOES • Battery levels for the adults who run your plan, with honest "last checked" times • A short list of people you can reach from any borrowed phone • Rescue sign-in from any phone with internet access and a supported browser • A calm heads-up at 10% and 5%, before your phone dies, not after • A practice run, so you know exactly what to do WHAT ZEROPERCENT DOESN'T DO • No location tracking • No message monitoring • No app-activity reporting The adults who run your plan see your battery, whether you're set up, and how many backup contacts you have, the number only. They never see who those people are. Reaching your people by text from a borrowed phone is free, for everyone on your plan, for good. Not on iPhone? The full ZeroPercent works in any browser at zeropercentapp.com. ZEROPERCENT PRO Paid plans add voice calls and unlimited backup contacts.

Asking family to confirm is now one tap. • When you ask someone on your plan to confirm, they get a notification in ZeroPercent and agree with one tap. No numbers, no links. • If they're not on the latest version yet, you can still text them the link.
