Your data stays on your computer.

What stays on your computer

Everything you work with in Revise is processed and stored locally, and is never uploaded to us or to any third party:

• Datasets, spreadsheets, images (including DICOM), text, and signal files
• Cleaning steps, visualizations, and session history
• Trained models, predictions, metrics, and reports

Revise saves its working files to ~/Library/Application Support/Revise on macOS and %APPDATA%\Revise on Windows. Its internal server listens only on your own computer (127.0.0.1) and rejects requests from websites, so other computers on your network can't reach it.

What the app sends to us

Update check. Each time Revise opens while you're online, it asks whether a newer version exists. That request contains only your operating system and the app version you're running (for example, platform=macos&current=1.0.0), with no account details or any other identifier. If there's an update, Revise shows a notice with the release notes. Installing it is always your choice.

Sign-in. When you sign in, Revise sends the email address you enter, and then the 6-digit code we email you, along with an anonymous identifier for your computer (a one-way hash that can't be reversed into a serial number), your operating system, and the app version. The server replies with a sign-in token for this computer and a signed license.

Account check. While you're online, Revise checks your plan in the background (on launch and periodically while it's open) so it knows when a trial ends or a payment goes through. Each check sends exactly this:

Authorization: Bearer <sign-in token for this computer>
{ "app_version": "1.0.0" }

Subscribing, managing billing, and joining a group send the same sign-in token, plus the group access code when you join a group. Payment details are entered on Stripe's checkout page in your browser, never in the app.

All of these requests go to https://www.revise.live/api/ over HTTPS. If your network uses an allowlist, that's the only Revise address you need to allow.

Pretrained model downloads

Some imaging and NLP workflows start from publicly available pretrained models. The first time you use one, Revise downloads its weights from the model's publisher (for example, Hugging Face or PyTorch) and stores them on your computer for reuse. These are downloads only: none of your data is sent. Tabular and signaling workflows don't need them.

Working offline

After you've activated it, Revise works without an internet connection. Your license is a signed file stored on your computer, so the app checks it locally. A paid license stays valid offline until the end of your current billing period plus a short grace period. Connect at least once before then so the app can pick up your renewal.

What we store about you

See the Privacy Policy for how long we keep it and how to have it deleted.

HIPAA and regulated data

Because your datasets never leave your computer, we don't receive, store, or transmit protected health information (PHI) on your behalf, so we don't sign Business Associate Agreements. Your organization remains responsible for securing the computers Revise runs on and for following HIPAA, IRB protocols, and internal policies for the data you use.
