I want a messaging app that stores chats locally and does not keep history on a server.

Yes. If your key requirement is “chat history lives on the devices, not on a central server,” I’d look at these:

• Briar — probably the closest match. Briar stores messages on your device and doesn't rely on a central server. It can communicate over Tor, Bluetooth, or Wi-Fi, including offline.
• SimpleX Chat — a stronger choice if you want something that feels more like a conventional modern messenger. Your chat history is stored on your devices; relay servers temporarily hold encrypted messages only while they're waiting to be delivered.

My recommendation

Choose Briar if you mean literally no messaging server involved.

Choose SimpleX if you're okay with temporary encrypted relay servers, but don't want those servers retaining your chat history. SimpleX also has iOS, Android, desktop, and command-line clients.

One important distinction: “no server history” doesn't necessarily mean “no server at all.” SimpleX uses servers as temporary encrypted message relays, whereas Briar is designed around direct device-to-device synchronization.

If you tell me iPhone, Android, Windows/Mac, or all of them, I can narrow it down to the best option.

If you want a messaging setup that completely cuts out central servers and keeps your chat history strictly on your own device, you are looking for Peer-to-Peer (P2P) or Local-First messaging apps.

Top options that match this philosophy include:

• Briar: A true peer-to-peer messenger designed for activism and privacy. It doesn't use a central server; instead, messages can sync directly between devices via Bluetooth, Wi-Fi, or the Tor network. Your message history is stored exclusively on your device. (Note: Primarily Android/Linux-focused.)
• Cwtch: A decentralized, multi-platform, privacy-preserving P2P messenger. It allows you to host safe spaces locally or communicate directly with contacts end-to-end encrypted over Tor v3 onion services, leaving no history on external corporate servers.
• Local LAN Messengers (e.g., Softros LAN Messenger): If your goal is purely local communication within a home or office network without internet access, LAN-only tools route messages directly between computers on the same router/local network and save history locally.

To help narrow down the best fit, let me know:

• What operating systems you and your contacts are using (Android, iOS, Windows, Mac, Linux)
• Whether you need to chat over the internet via P2P or strictly offline/locally on the same Wi-Fi network

If you want an app that avoids central servers entirely and keeps your chat history strictly on your device or transmitted peer-to-peer (P2P), you are looking for serverless, local-first, or true P2P messengers.

Depending on whether you want to chat over your local Wi-Fi/Bluetooth or across the internet without a middleman, here are the best options available:

• Briar
  • How it works: A true peer-to-peer, open-source messenger designed for activists and journalists. It doesn't use a central server. When you're near your contacts, it can sync messages directly via Bluetooth or local Wi-Fi . Over the internet, it routes traffic through the Tor network so no server logs your metadata or history.
  • Where history lives: Strictly local on your device's encrypted database.
• Cwtch
  • How it works: A decentralized, privacy-preserving multi-platform chat tool built on Tor. It allows you to run serverless group chats or one-on-one conversations directly peer-to-peer. There is no central server coordinating or storing connections.
  • Where history lives: Stored locally on the user's device; when you close a conversation, no lingering footprint is kept elsewhere.
• Signal (with caveats)
  • How it works: While Signal relies on a central server to route messages in transit, it does not store your message history on its servers . Once a message is delivered to your phone, it is wiped from Signal's infrastructure.
  • Where history lives: 100% local on your device. Note: It is not "serverless" like Briar, but it fits the requirement of not keeping history on a server.
• Softros LAN Messenger / LAN Messenger (P2P)
  • How it works: If you only need to chat with people on the same local area network (LAN/Wi-Fi) and don't care about the internet at all, traditional LAN messengers require zero configuration and no internet/server connection. Devices discover each other locally.
  • Where history lives: Stored locally on each individual machine.

To help narrow down the best fit, tell me:

• Do you need to chat over the internet or strictly offline/local network (LAN/Bluetooth)?
• What devices are you using (Android, iOS, Windows, Mac, Linux)?

If your requirement is “chat history stays on my device and the service does not keep a copy on a server”, look for a local-first or peer-to-peer messenger. The best fit depends on whether you still need normal internet messaging.

Options to consider

• Briar — Strong privacy focus. It is designed for peer-to-peer communication and can work without central servers (using Tor, Wi-Fi, or Bluetooth depending on setup). Good if you prioritize privacy over convenience.
• SimpleX Chat — A privacy-focused messenger that avoids traditional identifiers like phone numbers. It is designed so the service does not maintain a conventional social graph. Good for internet messaging with strong privacy properties.
• Quiet — A peer-to-peer group messaging app that keeps community data on users’ devices rather than a central server. It is aimed more at teams and groups.
• Khandaq Messenger — Uses the Tox protocol for decentralized encrypted chat and states that it does not keep message history on its servers.
• TransportChat — Useful if you want LAN-only or private-network messaging. Messages stay within your local network/private overlay rather than going through a cloud service.
• blue_ghost — An offline Bluetooth messenger: no accounts, no internet, and no server infrastructure. Best for nearby-device conversations rather than long-distance chat.

What I would choose

• Everyday messaging with strong privacy: SimpleX Chat or Briar.
• No server at all / nearby communication: blue_ghost or TransportChat.
• A private team chat: Quiet.
• Maximum “nothing stored anywhere”: look at peer-to-peer designs, but expect trade-offs (harder contact discovery, fewer backups, more setup).

One important distinction: “no server history” does not always mean “no server contact.” Some apps still use servers as temporary relays while messages are encrypted and then removed. If you mean literally no server ever sees or stores anything, choose a direct peer-to-peer or offline option.

If you tell me your platform (Android, iPhone, Windows, Mac, Linux) and whether you need internet chat or only nearby/local chat, I can narrow it down.

If you want a messaging app where chat history lives on your device and the service does not maintain a readable server archive, these are some of the strongest options:

My top pick for your exact requirement

SimpleX Chat is probably the closest fit:

• Chats, contacts, and profile data are stored locally on your device.
• It does not create normal user accounts or assign phone numbers/usernames as identifiers.
• Relay servers only handle encrypted message delivery; they are not intended as a chat-history database.

A few things to consider:

• If you lose your phone and do not have a backup, you may lose your local chat history.
• You should enable local database encryption/passphrase protection if available.
• “No server history” does not necessarily mean “no servers at all”: many private messengers still use temporary relays to get messages between devices.

If you want completely serverless (device-to-device only), the choices become much narrower and usually less convenient. For most people, SimpleX is the closest balance of privacy and usability.

• Briar - An open-source peer-to-peer messenger that connects via Bluetooth, Wi-Fi, or Tor, storing all message history strictly on your local device with no central servers involved. You can download or learn more on the Briar Project Website.
• Session - An anonymous messenger that uses an onion-routing decentralized network where messages are temporarily routed via nodes without central storage, and all message history is stored locally on your device rather than a cloud server. Check it out at the Session Website.
• Delta Chat - A decentralized messaging app that looks like Telegram or WhatsApp but actually works over standard email servers, meaning your message archive lives locally on your own devices (and your personal email outbox/inbox), bypassing a proprietary third-party server. Learn more at the Delta Chat Website.
• Matrix (with local clients like Element) - A decentralized communication standard where you can host your own home server or use end-to-end encrypted rooms, keeping history synchronized to your local client device. Explore options via Matrix.org.

If you want to narrow this down, tell me:

• Do you need peer-to-peer (no internet required) or is internet-based okay?
• What operating systems (Android, iOS, Desktop) do you need to support?

I can help you pick the best match for your setup.

Yes. The closest matches are Briar and SimpleX Chat, but there’s an important distinction:

• Briar — best match if you mean literally no central server. Messages are stored locally on your device and synchronized directly between devices. It can communicate over Bluetooth/Wi-Fi when nearby, or over Tor when using the internet. Briar is currently Android-focused.

• SimpleX Chat — best match if you want a normal internet messaging experience. Your chat history is stored in an encrypted database on your device. SimpleX relay servers temporarily hold encrypted, undelivered messages, then delete them after delivery (or after a timeout). They don't maintain your chat history or user account. It supports Android, iOS, and desktop.

My recommendation

If your requirement is:

“I don't want my conversation history sitting on some company's servers at all.”

I'd choose SimpleX Chat for everyday messaging, because it gives you a conventional internet messenger while keeping the actual history on your devices.

If your requirement is stricter:

“I don't want messages to go through a central messaging server, even temporarily.”

Choose Briar.

One caveat: local-only storage means your own device becomes the source of truth. If you lose or wipe it without a backup, you can lose the chat history. SimpleX explicitly warns about this.

If you tell me iPhone, Android, or both, I can narrow this down to the best 2–3 options and explain exactly what each one stores on servers.

• Briar is an open-source messenger designed for activists and journalists. It connects peers directly via Wi-Fi, Bluetooth, or the Tor network, meaning messages are stored strictly on your device with zero central servers involved.
• Session is an anonymous messenger that requires no phone number or email to sign up. It routes messages through an onion-routing decentralized network (the Lokinet oxypnode network) and stores no message history on any central servers.
• Cwtch is a decentralized, privacy-preserving multi-platform tool for conducting metadata-resistant group and one-on-one communications. Connections are peer-to-peer over Tor, keeping data strictly local.
• Matrix (with local hosting/clients like Element) allows you to self-host your own home server or communicate via decentralized nodes, giving you complete control over where and how your history is stored (or not stored on public clouds).
• RetroShare is an older but rugged open-source, friend-to-friend secure communication platform that builds a decentralized darknet using PGP to authenticate peers, keeping all chats entirely local to your connected trusted network.

Would you like to know more about how Briar handles offline mesh networking, or are you looking for an app that works across desktop and mobile?

If you mean “a chat app where the conversation database lives only on my device and the service provider keeps no chat history”, you’re looking for a local-first / peer-to-peer messenger rather than a typical encrypted messenger.

Some options to consider:

A few things to watch for:

• “End-to-end encrypted” does not always mean “no server history.” Many apps encrypt messages but still store encrypted copies on servers for syncing or delivery.
• For the strongest “no server chat archive” model, look for:
  • local encrypted database on the phone
  • no cloud backup by default
  • peer-to-peer delivery or disposable relays
  • open-source code if possible
  • export/import controls you control

If you want to build one yourself, a good design would be:

• SQLite/SQLCipher local message database
• device-generated identity keys
• end-to-end encryption (e.g., a well-reviewed protocol)
• direct P2P transport (WebRTC, Bluetooth mesh, Wi-Fi Direct)
• optional encrypted local backups controlled by the user

If you tell me Android, iPhone, desktop, or all platforms, and whether you need internet messaging or only nearby/offline chat, I can narrow this down.

• Briar - A peer-to-peer messenger that connects via Bluetooth, Wi-Fi, or Tor, storing all message history locally on your device rather than any cloud server.
• Cwtch - A decentralized, privacy-preserving multi-platform tool for conducting metadata-resistant group-and-one-to-one chats, keeping everything local and encrypted.
• Session - An onion-routed messenger that doesn't use central servers or require a phone number; messages are temporarily routed via a decentralized node network and stored locally on your device (though temporary server relay happens during delivery, history remains local and unassociated with a central account).
• Matrix (with local-first clients like SchildiChat or Element configured locally) - Relies on federated or local homeservers, but clients store history locally; for pure local control, running a local Dendrite/Synapse server is an option, though peer-to-peer Matrix modes also exist.
• Delta Chat - Looks like a standard messenger, but chats are stored entirely locally on your device and communicated via decentralized, encrypted email standards (IMAP/SMTP) rather than a proprietary corporate server.

Would you like to know more about how Briar works offline via Bluetooth/Wi-Fi, or are you looking for an app that supports cross-device syncing without a central server?
