Nuclear Guide
Nuclear Guide walks you through what to do in a nuclear emergency: the first minutes, sheltering, sealing your home, supplies and first aid. It works offline, and your notes stay on your phone.
A calm, offline plan for a nuclear threat
Calendar notes, the patient log, supplies and photos are stored only on your device, encrypted with AES-256, with the key held in the Android Keystore. There is no account, no ads and no analytics, and cloud backup is turned off. You can delete everything at once from the About tab.

Don't look at the flash: turn away and cover your head and neck. Once the blast wave passes, get into the nearest solid building or underground shelter; at home, move to an inner room without windows. Don't run home if reliable shelter is nearby. Then close windows and doors tightly and switch off ventilation.
A basement or underground parking, an inner hallway, a storeroom or a windowless bathroom. Rooms with large windows, balconies and cars offer poor protection from radioactive dust. Close windows and doors, turn off ventilation and air conditioning, and leave shoes and outerwear by the entrance.
The app's minimum kit: 3–4 L of water per person per day, non-perishable food, a flashlight with spare batteries, a power bank and cables, an AM/FM radio, a first-aid kit, an FFP2/N95 respirator and bags for contaminated clothing. Keep documents, cash and key contacts on paper together.
Only when officials announce a risk of radioactive iodine release. Potassium iodide saturates the thyroid; it does not protect the rest of the body from radiation. Taken without that advice it may be useless or harmful, especially with thyroid conditions. Until then, shelter, sealing and safe water come first.
Yes. Instructions, checklists, the calendar, the patient log and the supplies tracker all work offline. A connection is needed only if you choose to support the developer through Google Play. The app runs on Android 6.0 and later.
No. Nuclear Guide is an independent reference from RE:RiSE systems. It does not replace official alerts, sirens or instructions from emergency services. In an emergency, follow official announcements first and use the app as a supporting checklist.
Only on your phone, encrypted. We never receive them. Cloud backup is turned off, so your notes won't move to a new phone or survive a reset. That is by design, so sensitive data never leaves the device.
