HopChat – Offline Mesh Chat

No network? Keep talking, and even swap large files* like videos, with no internet. HopChat is an offline messenger: your messages travel directly from phone to phone over Bluetooth and Wi-Fi, with no internet, no data plan, no account and no phone number. At a festival, a concert, on a hike, in the subway, on a plane, during an outage or simply when the network is overloaded, you stay in touch with the people around you. CHAT WITH PEOPLE NEARBY Open the public chat and talk with everyone using HopChat around you. The "Autour de moi" (Nearby) screen shows who is there, each with a colorful avatar. YOUR MESSAGES GO FURTHER With relay mode, HopChat forms a mesh network: a message hops from phone to phone through other users, up to 5 hops, to reach people out of direct range (the message shows how many relays it went through). And when you meet a new phone, recent public messages are shared automatically, so you never miss the conversation. PHOTOS, VIDEOS AND LARGE FILES Send your photos and videos, up to 200 MB per file*, quickly and with no internet. For a voice message, hold the mic, talk, let go. That's it. In private chats, your photos, videos and voice messages stay end-to-end encrypted. PRIVATE MESSAGES THAT STAY PRIVATE Tap someone to message them privately. Private messages are end-to-end encrypted: only you and the other person can read them, even when they travel through other phones. Your history is encrypted on the phone. Verify your contact's identity by scanning their QR code or comparing the safety number. Contact out of range? The message waits and goes out as soon as they or a relay come within range (24 h at most). A double check mark confirms it arrived. NO ACCOUNT, NO PHONE NUMBER No sign-up, no email, no phone number, no ads. HopChat gives you a nickname that you can change at any time. Your conversations are stored on your phone, never on a server. YOU STAY IN CONTROL • Content filter: messages containing abusive terms are hidden automatically, and you can add your own words. • Block someone in one gesture: you will no longer see their messages. • Report a message or a person to the Hopcast moderation team, which reviews every report within 24 hours. • Emergency wipe: triple-tap the title to instantly erase messages, photos, videos, voice messages and nickname. GOOD TO KNOW • HopChat works between phones running the app, within Bluetooth and Wi-Fi range (no internet or Wi-Fi network required), and further through relays. • An internet connection is needed once, on first launch, to activate the app. After that, chatting works offline; reports are sent as soon as internet is available. • Keep HopChat open on screen to discover people nearby. • Public messages can be seen by everyone nearby: be kind. Following the Terms of Use is mandatory and abusive content is not tolerated. For ages 16 and up. • The app interface is available in English, French, Spanish, German, Italian, Portuguese, Dutch, Swedish, Danish and Norwegian. * Large files can't be exchanged between iPhone and Android due to technical limitations. Between the two, you share text, light photos and voice messages. Terms of Use: https://hopcast.fr/legal/hopchat-terms-of-use Privacy Policy: https://hopcast.fr/legal/hopchat-privacy-policy
