Chat Local vs OffNet Chat

Chat Local is the messaging app that works when nothing else does. Using Bluetooth mesh technology, you can send messages to people nearby — no internet, no cell service, no problem. __________________________________ PERFECT FOR • Desert festivals and burns (no cell towers for miles) • Music festivals and concerts (overloaded networks) • Camping, hiking, and backpacking trips • International travel (avoid roaming) • Airplanes, basements, and parking garages • Emergency preparedness when towers are down __________________________________ HOW IT WORKS Open the app, pick a name, and start chatting. Messages travel directly between phones over Bluetooth, hopping through other users to reach people farther than Bluetooth alone would carry — and they keep arriving while Chat Local is in the background and your phone is locked. Just leave it running rather than force-quitting it. __________________________________ KNOW WHAT HAPPENED TO IT Every message shows its status — sending, sent, or received by however many nearby devices confirmed it. You see what the app actually knows. (Much older versions don't send confirmations, so a message can arrive showing only "Sent".) __________________________________ FREE FEATURES • Bluetooth mesh messaging that works with no signal • Delivery confirmations • Works completely offline, including airplane mode • No account or sign-up required • Discover and preview nearby conversations • Join up to 2 conversations • Profanity filter for family-friendly chats • Battery-optimized Bluetooth Low Energy __________________________________ CHAT LOCAL PRO • Unlimited conversations instead of 2 • 400-character messages instead of 50 • 500 messages of history per conversation instead of 20 • Password-protected conversations, with a lock on each message that went out protected • Message search, with jump-to-message • Export a full conversation transcript • 10 themes, 8 chat backgrounds in light and dark, and a bubble color per person • Block anyone you'd rather not hear from • Network view of every nearby device • Keyword alerts, and notifications for new nearby conversations • Send every half second instead of every five TRY BEFORE YOU BUY Tap any locked theme, background or sender color to see it applied to your real conversation right away — no purchase, no sign-up. __________________________________ YOUR PRIVACY MATTERS • Messages never touch our servers — there are no servers • No cloud storage of any kind • No account means no personal data to breach • Every message is protected in transit by default • Optional password protection for a conversation (Pro) Conversation and display names are broadcast to nearby users so discovery works. __________________________________ GOOD TO KNOW Chat Local needs Bluetooth on and works best within roughly 10-30 meters, farther when others relay along the way. The more people nearby running it, the better it works — bring a friend. Bluetooth messaging between moving phones is never guaranteed. Range, obstacles, crowds and battery savers all affect whether a message gets through, and one that can't reach anyone won't be delivered. 2.0 makes delivery considerably more reliable, but it improves the odds rather than promising them. Never rely on Chat Local as your only way to reach someone in an emergency. Everything except buying Pro works offline, so upgrade before you leave signal; what you bought keeps working offline. Conversation passwords are never stored and can't be recovered by anyone, including us. Once you unlock a conversation, a key derived from your password is kept in the device Keychain so it stays unlocked. Pro is a monthly or yearly subscription, or a one-time purchase that unlocks everything forever. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in your App Store account settings.

OffNet Chat is a private messenger that works in places other messengers can't — and collects nothing, anywhere. NO SIGNAL? NO PROBLEM. At a festival, on a flight, hiking off-grid, or when the network is down: OffNet Chat sends messages directly between iPhones over Bluetooth and peer-to-peer Wi-Fi. Phones running OffNet Chat can quietly pass messages along for each other, so your words can hop through the crowd to reach a friend across it — and every hop only ever carries scrambled data. FAR APART? STILL PRIVATE. Turn on the internet bridge and message friends anywhere in the world. Messages travel as anonymous, end-to-end encrypted parcels through rotating mailboxes that can't be linked to you — no servers of ours, no accounts, no metadata trail. NO ACCOUNTS. NOTHING COLLECTED. There is no sign-up. Your identity is a cryptographic key created on your phone, and it never leaves your phone. We have no servers, no analytics, no ads, no tracking — we couldn't read your messages or sell your data even if we wanted to, because we never have either. EVERYTHING YOU EXPECT FROM A MESSENGER • Text, photos, and voice notes — all end-to-end encrypted • Photos send instantly as previews, then upgrade to high quality over Wi-Fi, Bluetooth, or the bridge • Delivery ticks and icons showing which path each message took • Background notifications that decrypt privately on your device • Profile photos that sync to your friends automatically ADDING FRIENDS IS EFFORTLESS • Nearby: one of you scans the other's QR code — the other phone gets a simple accept prompt • Far away: share a one-time invite link over any app you already trust • Verify any friendship in person later with safety codes, like the pros do YOU'RE IN CONTROL • Three transport switches — Bluetooth mesh, Wi-Fi, internet — each one yours to flip • Block anyone, with a choice: notify them, or block quietly so they learn nothing • See exactly how much you've sent today • Delete your identity and every trace of your data, irreversibly, any time HONEST ENCRYPTION Modern, audited primitives from Apple's CryptoKit: Curve25519 key agreement and ChaCha20-Poly1305 encryption, end to end. Relay phones and the optional cloud mailboxes only ever see ciphertext. OffNet Chat does not yet implement forward secrecy (it's on the roadmap) — we'd rather tell you that than overpromise. OffNet Chat asks only for the permissions it visibly uses: Bluetooth and local network to reach nearby phones, camera to scan QR codes, microphone for voice notes you record, and notifications. Your words, your phone, your business.
