## What it is
Peergos is a peer-to-peer, end-to-end encrypted global filesystem with fine-grained cryptographic access control, built on IPFS/libp2p with post-quantum security. It also provides a secure messenger, encrypted email client, and a private social network where users control who sees what.

## Use cases
- store files encrypted in a decentralized p2p cloud
- share files and folders via secret links without accounts
- run a private social network where I control who sees my posts
- self-host my own encrypted cloud storage server
- chat and email with end-to-end encryption
- protect my data from surveillance including friendship graph metadata
- back up photos and documents privately across devices

## When to choose
- you want user-owned, end-to-end encrypted storage resistant to surveillance
- you need decentralized sharing without trusting a central provider
- you want post-quantum cryptography and cryptographic access control
- you prefer self-hosting your data on IPFS-compatible infrastructure

## When to avoid
- you need mature integrations with mainstream cloud ecosystems or standard S3 APIs
- you require high-performance POSIX filesystem semantics or local disk mounting at scale
- you want a widely adopted platform with a large user base and third-party app ecosystem
- you need simple drop-in cloud backup with minimal setup
