Privacy Policy

The short version

Revise is a desktop application that runs on your own computer. The datasets you load, the models you train, and your results never leave your computer and are never sent to us. We only collect what we need to sell you a license and keep it working: your contact details, your license and billing status, and a little information about the computers your license is active on.

For a technical breakdown of exactly what the app sends over the network, see Data & Security.

Who we are

Revise is operated by Aadi Ajmire, doing business as Revise ("Revise", "we", "us"). You can reach us at contactreviseml@gmail.com.

Information we collect

Account information

When you sign in, we collect your email address, and optionally your name, phone number, and organization. We keep a record of your plan (free trial, individual subscription, or group subscription), when your trial or subscription starts and ends, when you agreed to the trial terms, and which group you belong to, if any. To sign you in we email you a one-time code, which we store only in hashed form and which expires after 10 minutes.

Device information

When you sign in, and when the app checks your plan while you're online, it sends us:

• a sign-in token for this computer (we store only a hashed copy)
• an anonymous identifier for your computer: a one-way hash that can't be reversed to reveal your hardware or identity
• your operating system (macOS or Windows) and the Revise version you're running

Separately, each time Revise opens while you're online, it checks whether a newer version exists. That check sends only your operating system and app version, with no account details or other identifier.

We record when each computer was first and last seen. Like any website, our servers also receive your IP address when the app or your browser contacts them. Our hosting provider may keep it briefly in its logs, but we don't store it in our customer records.

Payment information

Payments are handled by Stripe. Your card details go directly to Stripe and are stored by Stripe if you choose to keep a card on file. We never see or store your full card number. Stripe shares with us your subscription status, payment history, and limited card details (such as card brand, last four digits, and billing country) so we can manage your subscription.

Communications

If you email us, we keep that correspondence so we can help you.

Website analytics

Our website uses Vercel Web Analytics, which counts page visits in aggregate without cookies and without tracking you across other sites.

What we don't collect

• The contents, names, or structure of any dataset, image, text, or signal you load into Revise
• The models you train, their predictions, or your results
• Usage analytics, telemetry, or crash reports from inside the app

The only way any of that reaches us is if you choose to send it, for example by emailing us a file while asking for support.

How we use information

• To sign you in, check which plan you're on, and enforce its limits (such as one free trial per person and per computer, two computers per account, and the seat count of a group)
• If you join a group subscription, to tell the person who bought it which email addresses are using its seats
• To process payments and manage your subscription
• To send you service emails, such as receipts, trial-ending reminders, payment problems, and important security notices
• To tell you about new versions and features, only if you've opted in. You can unsubscribe at any time.
• To respond to support requests
• To prevent fraud and abuse, and to meet legal, tax, and accounting obligations

Service providers we use

We share information only with companies that help us run Revise, and only what they need to do that job:

We do not sell your personal information, and we do not share it for advertising.

How long we keep it

We keep account and license records for as long as you have a trial or subscription, and for up to seven years afterward where needed for tax and accounting. If you ask us to delete your information, we'll delete it except for records we're legally required to keep.

Security

All communication between the app, our website, and our servers is encrypted (HTTPS). Customer records are stored in a database that only our server can access. Licenses are cryptographically signed so they can be verified on your computer without sending anything else to us.

Health and other sensitive data

Revise is designed for sensitive data, including clinical data, because that data stays on your computer. We do not receive, store, or process protected health information (PHI) from your datasets. You remain responsible for protecting that data on your own devices and for following any rules that apply to it, such as HIPAA, IRB protocols, or your institution's policies.

Your rights

Wherever you live, you can ask us to access, correct, export, or delete the personal information we hold about you, or to stop sending you marketing email. Email contactreviseml@gmail.com and we'll respond within 30 days. We won't treat you differently for making a request.

California residents have these rights under the California Consumer Privacy Act. We do not sell or share personal information as those terms are defined in that law.

If you're in the EU, UK, or Switzerland, we process your information to perform our contract with you (your license and subscription), based on our legitimate interests (preventing abuse and improving Revise), to meet legal obligations, and with your consent for product-update emails. Your information is stored and processed in the United States. You also have the right to object to processing, to restrict it, and to complain to your local data protection authority.

Children

Revise is not intended for anyone under 16, and we don't knowingly collect their information.

Changes to this policy

If we make material changes, we'll update the date above and email customers before the changes take effect.
