Does Witness encrypt video? What protects footage and what does not

A direct answer to a question that deserves one.

People reasonably ask whether footage recorded with Witness is encrypted. The honest answer is that Witness does not add an encryption layer of its own, and this page explains what that means in practice. Written by the developer of Witness Camera, so read it with that in mind; where another approach is better, it says so.

Short answer. No. Witness does not add its own encryption to footage. It relies on your phone's protections (a strong passcode) and on the storage provider you connect. It has no server of its own, so there is no Witness copy to be breached or subpoenaed, and the only thing sent to a third party besides your storage is a hash of the manifest. Footage in Google Drive or Dropbox is subject to those providers' security and legal process. If you need files encrypted as they are captured, hidden from the gallery or an app that can disguise itself, look at Tella.

What protects footage in Witness

Your phone's passcode. Use a six-digit code rather than biometrics.
Your storage provider's security. Footage goes to the account you connected and nowhere else.
No developer server. There is no Witness backend to breach, and the developer cannot see, retrieve or produce footage.
Integrity checks. SHA-256 hashes and an independent time-stamp show whether files have changed, which is about tamper-evidence, not secrecy.

What it does not do

No end-to-end encryption of footage by Witness.
It does not hide the app or the recording. iOS shows a green recording dot and Android a notification.
It does not conceal files from someone who unlocks your phone.
Footage in a US cloud provider is reachable by legal process served on the provider. A Nextcloud or WebDAV server you run avoids that.

Integrity is not secrecy

Hashing and time-stamping make footage tamper-evident: anyone can check it has not changed. They do not make it confidential. Those are different properties, and many people mix them up.

If you need encryption

From its own site, read on 27 October 2026, Tella (Horizontal, a US nonprofit) is free and open source for Android and iOS, encrypts files as they are captured, hides them from the gallery and can disguise the app. If your risk is a device search, compare it on our comparison page. Witness is for getting footage out of the phone and making it checkable.

Questions

Is Witness footage encrypted?

Witness adds no encryption layer of its own. It relies on your device passcode and your storage provider, and has no server of its own.

Can the developer see my footage?

No. There is no server and no account system. Footage goes from your phone to the storage account you connected.

What is the difference between hashing and encryption?

Hashing makes footage tamper-evident: it shows whether a file changed. Encryption makes it unreadable without a key. Witness does the first, not the second.

Which app encrypts files as they are captured?

Tella, per its own site, encrypts files as they are captured and can hide them and disguise the app. Compare it before relying on Witness where a device search is the risk.
