cloud sync lets you access your screenpipe data across all your devices with end-to-end encryption. we use zero-knowledge encryption, meaning we physically cannot read your data.

​
zero-knowledge encryption

your data is encrypted on your device before it ever leaves. we use your password to derive an encryption key locally - this key never leaves your device and we never see it. this means we physically cannot read your data, even if we wanted to. only you (and anyone you share your password with) can decrypt your data.

​
how it works

1

you set a password

this password is used to derive your encryption key using argon2id (a secure key derivation function).
2

data is encrypted locally

before any data leaves your device, it’s encrypted using chacha20-poly1305 (a fast, secure cipher).
3

encrypted data is uploaded

only encrypted blobs are sent to our servers. we store them but cannot read them.
4

other devices decrypt locally

when you access data from another device, it’s downloaded and decrypted on that device using your password.

​
what we store

  • encrypted blobs (we cannot read these)
  • your account email
  • encrypted master key (encrypted with your password - we cannot decrypt it)
  • salt for key derivation (not secret, needed to derive the same key)
  • device metadata (device name, os, last sync time)

​
what we cannot see

your screen recordings

all visual data is encrypted

your audio transcriptions

all audio data is encrypted

your ocr text

all extracted text is encrypted

your encryption password

never leaves your device

your encryption key

derived locally, never transmitted

any of your actual data

we only see encrypted blobs

​
verify it yourself

screenpipe is open source. you can audit the encryption code yourself:

view encryption source code

review the rust implementation of our zero-knowledge encryption

​
important notes

if you forget your encryption password, your cloud data cannot be recovered. we recommend using a password manager.
cloud sync requires a screenpipe pro subscription. sync happens automatically in the background and uses approximately 0.8 gb per monitor per day.
