Flingr - Secure, Ephemeral, Messaging

flingr is a next-generation secure messaging app designed to offer unparalleled privacy through a unique "single-copy" messaging system. At any point, only one copy of a conversation exists.

Features

With these secure messaging and encrypted calling features, you can express yourself freely and privately.

End-to-End Encryption

All messages, images, and videos are encrypted using AES-256 encryption with randomised key changes to ensure they are protected throughout their journey from sender to recipient.

Customizable Deletion Timers

All messages and conversations will be set to delete if not collected within a set timeframe.

No User
Identifiable Data

flingr does not store any user-identifiable information on its servers, or in the app, ensuring full anonymity for you and your contacts.

Single-Copy Architecture

Messages exist in only one place at a time—on the sender’s device, on the server for a limited time, or on the recipient’s device—ensuring there is no persistent data stored.

Secure Invite System

Invitations to connect on flingr are sent via email from a secure server, with all metadata and invite details deleted immediately after sending. All of your contacts have an alias, and real names, emails addresses, phone numbers etc are never stored anywhere in the app or on our servers.

Point-to-Point Voice & Video Calls

Fully encrypted calls and video calls with no logs. Calls leave no trace; once a call ends, no records, metadata, or connection logs are kept.

How it works

When you send a message, it is securely sent to a random server.

Once delivered to the recipient, the message is deleted from our server.

The conversation exists only on your device or your contact’s device—never both at the same time.

If there’s no reply, the message is deleted when you leave the conversation, ensuring no trace is left.
