Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://alertfriends.app/privacy AlertFriends is a Personal Protection system designed for people who live alone, travel alone or spend many hours without company. The app lets you set up life checks to confirm that you are okay at specific times of the day. If you do not respond within the set time, AlertFriends can send an alert to your trusted people so they know that something may be happening. It is not just a reminder app. AlertFriends is designed as a personal safety network: you choose who receives alerts, when checks take place and which level of protection you need. Who is AlertFriends for? AlertFriends can be useful for: People who live alone. People who travel alone. Separated, widowed or single people who spend a lot of time without company. Families who want more peace of mind when a loved one lives alone. People who want a simple alert system if they cannot respond. Users who want to strengthen their personal safety without relying on manual calls. How does it work? Set up one or more life checks for the times when you want AlertFriends to check that you are okay. If regular activity is detected or you confirm that you are fine, nothing happens. If you do not respond, AlertFriends can activate your alert protocol and notify your trusted people. Depending on your protection level, your contacts may receive alerts through the app, SMS, WhatsApp, phone call and location. Basic Protection With Basic Protection, you can start using AlertFriends and add one trusted person to receive basic in-app alerts. It is a simple way to test the system and understand how your personal safety network works. Active Protection With Active Protection, you can strengthen your alerts and expand your safety network. It includes more contacts, more life checks and reinforced alerts by SMS and WhatsApp to increase the chances that someone sees the alert in time. Total Protection Total Protection is designed for those who want maximum peace of mind. It allows unlimited life checks and adds phone calls and location sharing in case of alert. If you live alone or travel alone, having more checks and more alert channels may help your trusted people react sooner if something is not right. Different from other check-in apps AlertFriends does not simply ask once a day if you are okay. The app is designed as a more complete personal protection system: Configurable life checks. Connected trusted people. Automatic alerts if you do not respond. Different protection levels. SMS, WhatsApp and calls depending on the plan. Location sharing in case of alert. Designed for people who live or travel alone. Clear, serious and easy-to-use design. More peace of mind for you and for those who care about you Living alone should not mean going unnoticed if something happens. AlertFriends helps you create a simple safety network: your phone checks that you are okay and, if you do not respond, your trusted people may receive an alert. Important AlertFriends is a support and personal protection tool. It does not replace emergency services, does not guarantee detection of every situation and does not ensure that your contacts will respond. In an emergency, always contact your local emergency services.
