Crate Systems
AI Usage Policy
Effective 27 September 2026, last updated 25 October 2026
Our products have one assistant, Cory: inside Crate Mail, as the Cory app on your Mac and in iMessage, and as Ask Cory on document share links. This page says which features use a model, what each one sends and when, who receives it, and what is never done with it. Sections 1 to 5 are about Crate Mail; section 6 is about the Cory app and Ask Cory. The Privacy Policy covers everything else the products do.
1. When Cory runs
Cory is part of Crate Mail. It runs whenever you are signed in to your Crate account, or whenever a key of your own is saved in Settings, and there is no setting that turns it off. Two features run on their own, without your asking, and section 2 marks them: sorting new mail into views written as a sentence, which includes the Important view Crate Mail starts with, and suggested replies. Mail, search, views built from rules, the calendar, and connector cards do not use a model.
2. What is sent, and when
Crate Mail sends text from your Mac, through our server (or, with a key of your own, directly), to Anthropic’s API. Our server checks that you are signed in, counts the request against your plan, and passes it on; it does not keep the text. Some features run only when you ask; some run on their own, and those are marked.
| Feature | When | What is sent |
|---|---|---|
| Sorting new mail into your views | On its own, as mail arrives, for each view written as a sentence, including the Important view | The view’s sentence; senders you moved in or out of it by hand; for each new thread the sender’s name and address, subject, and first 120 characters, at most 60 threads at a time |
| Suggested replies | On its own, when you open a thread from a person | Subject, up to 2,000 characters of the latest message, your writing style |
| Showing what a view would hold | When you make or edit a view | The view’s sentence; sender, subject, and first 120 characters for up to 60 recent threads |
| Setting up your first views | The first time you open Crate Mail, if you describe views then | Each sentence (to name the view); sender, subject, and first 120 characters for up to 250 threads from the last 90 days |
| Drafting in the reply box | When you press space and ask | Subject, what you have written so far, recipients’ names (or addresses where there is no name), your instruction, the previous draft if you ask again, your writing style |
| Drafting from the command menu | When you ask | Subject, up to 2,000 characters of the latest message, your instruction, your writing style |
Attachments, images, and the full HTML of a message are not sent. Nothing about your mail is sent in the background for any purpose other than the rows above.
3. Who runs the model
Anthropic runs the model (currently Claude Haiku 4.5) and receives the text in section 2, and processes it to return a response. Under Anthropic’s commercial terms, inputs and outputs of its API are not used to train its models, and Anthropic keeps them only for the limited period those terms allow, including for safety and abuse monitoring. If a key of your own is saved in Settings (possible only in a build without a built-in key, or kept from an earlier version), Cory uses it instead, and your text is processed under your own agreement with Anthropic. We may change the model or the provider; if the provider changes, this page will name the new one before it is used.
4. What is never done with it
- We do not use it to train or improve any model.
- It is not stored on Crate Systems’s systems, and no person here reads it.
- It is not used for advertising, profiling, or sale.
- In Crate Mail, Cory does not send mail, delete mail, or act on a connected service by itself. Every draft waits for you to send it, and every action waits for you to press it.
Where the text comes from Gmail, these commitments are also those of the Google API Services User Data Policy’s Limited Use requirements, as the Privacy Policy sets out.
5. What Cory gets wrong
Cory predicts text. It can misread a message, put mail in the wrong view or leave it out of the right one, suggest a reply that misses the point, or state something that is not true. Read a draft before you send it, and do not rely on a view built from a sentence as the only place you look for something that matters. You can check what a view would hold before you keep it, and see and edit the rules it is read into.
6. The Cory app and Ask Cory
- The Cory app. When Cory answers you with a model in the cloud, in iMessage or in its window on your Mac, it sends the message content the task needs: your message, the conversation around it, and what it needs to do what you asked, such as a file you named or a reply from a connected service. Chats you type in the Cory window are also kept on your Crate account so they survive a reinstall, as the Privacy Policy says.
- Ask Cory on a document share. When someone viewing a document share asks Cory a question, the document’s text and the question are sent to Anthropic to answer it.
Where Anthropic runs the model, the terms in section 3 apply. The model Cory uses varies by plan, and some replies may be made on your Mac without leaving it. We do not use any of it to train a model.
7. Limits
AI features are metered per plan. In Crate Mail, each plan includes a monthly allowance of Cory requests, which resets on the 1st, and requests in quick succession may be slowed for a minute. A feature may also stop for the rest of the day if a daily cap across the whole service is reached.
