by TypeSafe AI, Inc.

TypeSafe AI keeps two sets of terms. The Master Customer Agreement governs the product. The Terms of Use governs the website. Both are public, and you can switch between the two reads below.
This is a full commercial agreement, dense with defined terms and long all-caps blocks for liability, disclaimers, and arbitration.
The agreement that actually governs Jev keeps your inputs and outputs yours, and TypeSafe will not train on your data without your consent.
The Services are the TypeSafe-hosted console at console.typesafe.ai and the API. You get a limited license to use them for the length of your deal. On ownership the agreement is plain: TypeSafe does not claim your Input, disclaims the Output, and assigns the Output to you. TypeSafe keeps everything on its own side, the Services, the Telemetry, and the technology behind them.
"TypeSafe grants to Customer a limited, non-exclusive, non-transferable, non-sublicensable license during the Term to: (a) access and use the Services in accordance with the applicable documentation made available by TypeSafe from time to time"Section 2.1 · License
"TypeSafe does not claim ownership of Input and TypeSafe disclaims ownership of Output. TypeSafe hereby assigns to Customer all of its right, title, and interest, if any, in the Output."Section 4.2 · Output
TypeSafe and its licensors keep all rights in the Services, Documentation, Telemetry, and TypeSafe technology, and any product feedback or suggestions you send, it "may use and exploit... without restriction or obligation" (Section 11).
Day-to-day use comes with hard limits. You cannot use the Services or Output to distill or train a competing model, reverse engineer them, or exceed the Usage Limits. You carry the Input: its content, its accuracy, and every consent needed for TypeSafe to process it. Where your Input holds personal data, the Data Processing Addendum makes TypeSafe a processor that acts only on your written instructions.
"Customer will not do (and will not attempt to do)... (b) use the Services or any Output... to perform model distillation, train a model to imitate the output of the Services, or develop (or to facilitate the development of) a similar or competing product or service"Section 2.3 · License Restrictions
"Customer is responsible for Input, including its content and accuracy, and will comply with Laws when using the Services."Section 5 · Customer Obligations
On personal data the Data Processing Addendum makes TypeSafe a processor that "will only Process Customer Personal Data to provide the Services and in accordance with Customer's documented instructions," will not sell or share it, gives you fifteen days to object to a new subprocessor, and reports a security incident within seventy-two hours (Data Processing Addendum, Sections 2.1, 2.2, 3.2, 5.2). TypeSafe may suspend access for a breach, a payment thirty days overdue, a change in law, or risk to other customers (Section 6).
This is where the product terms stand apart. TypeSafe will not include your Customer Data in a training set without your prior consent, and the Privacy Policy repeats the promise for your Input. The one wide opening is Telemetry: the logs, hashes, statistics, and "learnings" about how you use the Services, which TypeSafe may process without restriction and keep for good.
"The foregoing license does not grant TypeSafe the right to, and TypeSafe will not, include Customer Data in a dataset used to train (i.e., to modify the model weights of) any artificial intelligence or machine learning models without Customer's prior consent."Section 4.1 · Use of Customer Data
"We will not train or fine tune any artificial intelligence or machine learning models on your prompts or other Input."Privacy Policy · Personal Data We Collect
The Privacy Policy also says TypeSafe "will not disclose any Input to a third party other than our service providers," and that it may make "anonymized or aggregated data that we may use for lawful purposes" (Privacy Policy). The training bar turns on "Customer's prior consent," and the agreement does not say how that consent gets asked for or given (Section 4.1).
Disputes leave the courts. You arbitrate individually through JAMS and give up class actions and a jury, with no opt-out. Liability on both sides is capped at the greater of twelve months of fees or fifty dollars. Indemnity runs both ways: TypeSafe covers third-party claims that the Services infringe United States intellectual property, and you cover claims about your Input. When the deal ends, TypeSafe can delete your Customer Data whenever it likes. California law governs, and TypeSafe can change the agreement on sixty days' notice.
"EACH PARTY'S... ENTIRE LIABILITY ARISING OUT OF OR RELATED TO THIS AGREEMENT WILL NOT EXCEED IN AGGREGATE THE GREATER OF (A) THE AMOUNTS PAID OR PAYABLE BY CUSTOMER TO TYPESAFE... DURING THE 12 MONTHS PRIOR... AND (B) $50 USD."Section 12.2 · Liability Cap
"CUSTOMER AND TYPESAFE AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN CUSTOMER'S OR TYPESAFE'S INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING."Section 15.7 · No Class Actions
The indemnity is two-way: TypeSafe defends you against claims that the Services infringe a U.S. patent, copyright, trademark, or trade secret, while you defend TypeSafe against claims about your Input (Sections 13.1, 13.2). On termination TypeSafe "will be under no obligation to store or retain Customer Data and may delete Customer Data at any time in its sole discretion" (Section 10.3). There is no arbitration opt-out here, unlike the website terms (Section 15).
Each item below is quoted and located in the documents.
It is short and boilerplate, and the reading is not the hard part; the terms you would actually need are in the product agreement on the other tab.
These terms cover TypeSafe's website only. The terms for the product are in the Master Customer Agreement, on the Product terms tab.
This page barely mentions a product. It covers the website, and it says outright that using any real TypeSafe product runs on a separate agreement, the Master Customer Agreement, read on the Product terms tab. The license on this page lets you browse the site, nothing more.
"These Terms of Use are a legally binding contract between you and TypeSafe regarding your use of the Site. If you enter into a separate agreement with TypeSafe for the use of any TypeSafe products or services... the terms of that separate agreement will govern your access to and use of those products and service."Preamble
"TypeSafe grants you, solely for your personal use, a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Site."Section 3(a) · Limited License
How the product treats you, your data, and what you make with it is set out in the separate Master Customer Agreement, shown on the Product terms tab.
The usual browsing rules apply: no illegal use, no touching or copying the site, no reverse engineering, no scrapers or bots. The site is meant for visitors in the United States, and reaching it from anywhere that makes access illegal is off-limits.
"you may not: (i) use the Site for any illegal purpose... (v) reverse engineer or otherwise attempt to discover the source code... or (vi) use... 'robots,' 'spiders,' 'scrapers,' 'webcrawlers,' or other computer programs that monitor, copy, or download data or other content"Section 3(b) · License Restrictions
"The Site is intended for visitors located within the United States. TypeSafe makes no representation that the Site is appropriate or available for use outside of the United States."Section 13(g) · International Use
"unauthorized use" and "misuse" set off your indemnity, and the document defines neither (Section 9).
The one clause here with real weight is about feedback. Whatever you send counts as non-confidential, and you hand TypeSafe a perpetual, irrevocable, sublicensable right to use it for anything. They also tell you flat out to keep anything confidential off the site. There is no training clause here; this page covers the website, and the product terms are on the other tab.
"Do not submit any information or other materials that you consider confidential or proprietary through the Site."Section 3(c) · Information You Submit
"you hereby grant TypeSafe an unrestricted, perpetual, irrevocable, non-exclusive, fully paid-up, royalty-free, transferable, sublicensable right to exploit the Feedback in any manner and for any purpose, including to improve the Site and create other products and services."Section 3(c) · Information You Submit
Whether the product trains on your inputs is covered in the Master Customer Agreement, on the Product terms tab. This page does not cover it.
Disputes go to individual arbitration through JAMS, and you give up class actions and a jury. You can opt out, but only by mailing a paper letter inside thirty days. The most you can recover is a hundred dollars. You indemnify TypeSafe one way. They can change the terms whenever they like and hold you to the latest version each time you visit, and Delaware law governs.
"YOU AND TYPESAFE AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING."Section 12(h) · No Class Actions
"THE AGGREGATE LIABILITY OF TYPESAFE TO YOU FOR ALL CLAIMS... IS LIMITED TO $100 USD."Section 11(b) · Limitation of Liability
The arbitration opt-out needs a letter in the post inside thirty days, and small-claims, agency, injunctive, and IP suits stay out of arbitration (Section 12).

Taken from the documents and sorted by what you need.
This explains what the documents say. It does not read the law for you, weigh whether a clause would hold up, or guess what happens if you break the terms. It is not legal advice, and it does not judge TypeSafe. Every quote is word-for-word from its source: the Master Customer Agreement and Terms of Use updated 19 September 2026, the Privacy Policy updated 19 November 2025, and the Data Processing Addendum updated 24 April 2026. The Terms of Use was read on 22 September 2026, and the Master Customer Agreement, Privacy Policy, and Data Processing Addendum on 23 September 2026. The separate product agreement is the public Master Customer Agreement, now read and folded in, so this covers both the product and the website terms.
