This page says what Hemmingway keeps when you use it, on your computer and on our server, in plain terms.

The desktop app

The desktop app keeps your chats, people and memory in files on your own computer. Your sign-in token is kept separately, in your operating system's secure keychain.

Your account

When you make an Hemmingway account, our server keeps:

• Your email address and name.
• Your picture from Google, if you sign in with Google.
• If you sign in with Google, the sign-in token Google gives us, which only reaches your name, email address and picture.
• Your password, if you set one. We keep only a hash of it, never the password itself.
• A record of each sign-in, with the device's IP address and the name of the app or browser you used.
• How much you have used Hemmingway in each 5-hour period.

We keep your email, name, picture and password hash for as long as your account exists. We keep a sign-in record for up to 90 days after you last used it, then remove it. We keep usage counts for 90 days.

Your chats, memory and People

When you are signed in, our server keeps your chats, memory and People, and your name and appearance settings, so they are the same in the desktop app and on the web. They stay until you delete them.

How we use your chats

We use your chats and memory internally to improve Hemmingway. We never sell them. We don't use your People for this.

Requests to the model

When Hemmingway asks the model a question, from the desktop app or the web, the request passes through our server and on to the machine that runs the model. Our server doesn't keep the request itself. It logs the request's token counts, how long it took and whether it worked, never its content.

Two answers

Now and then Hemmingway shows two answers and asks which you like more. One comes from another company's AI model, so that message and the chat before it go to that company through OpenRouter. We keep both answers and your pick to improve Hemmingway.

Payments

Stripe handles payments and sees your card. Our server never does. It keeps your plan, your Stripe customer id, and the amounts of API credit you buy and use.

Crash reports

If you turn on crash reports, a report can hold the app's version, your operating system, where the crash happened, the error message and the names of the functions involved. We remove anything that looks like a folder path or an email address before we keep it. A crash report never includes your messages, prompts or name, and is not tied to your account. We keep crash reports for 90 days.

Services we use

Hemmingway runs on a few outside services:

• Vercel hosts our server and this website.
• Neon holds our database.
• Resend sends the sign-in code emails.
• Stripe handles payments.
• Google, if you choose to sign in with Google.
• OpenRouter, which passes a chat to another company's AI model when Hemmingway shows two answers.
• A rented machine that runs the model.

Your data, and deleting it

From Hemmingway's settings you can download everything our server keeps for you as one file, or delete all your chats, memory and People and keep your account. You can also delete your account at any time. This removes everything listed above that our server keeps for you.
