**CAT SOFTWARE LICENCE TERMS AND CONDITIONS OF USE**

(Starter, Professional and Team Plans)

_Effective date: September 1<sup>st</sup> 2026_

These CAT Software Licence Terms and Conditions of Use (the "Terms") govern the licence and use of the CAT Software supplied by **Data Tools s.r.o., Company ID: 19386788, with its registered office at V Přístavu 1585/10, 170 00 Prague 7, Czech Republic, registered in the Commercial Register maintained by the Municipal Court in Prague, Section C, Entry 385814/MSPH** ("DT"). The CAT Software is DT's software product for data testing.

For these Terms, "Customer" means the person or entity that obtains, purchases or administers a CAT Software plan, "Authorised User" means a named individual permitted to use it, and "User" means the Customer and each Authorised User, as the context requires.

## 1\. Scope and acceptance

**1.1** These Terms apply to the subscription plans for use of the CAT Software. Any other individually negotiated arrangements are governed by a separate written agreement and are not supplied under these Terms.

**1.2** The User accepts these Terms by accepting them at checkout or by creating an account in the CAT Portal, or by downloading, installing, accessing or using the CAT Software. A person accepting on behalf of an organisation confirms that he or she is authorised to bind it. The Customer must ensure that all Authorised Users comply with these Terms.

**1.3** The CAT Software is available at <https://portal.justcat.it> (the "Portal") and at marketing site [www.justcat.it](http://www.justcat.it) . Current product documentation is available at <https://docs.justcat.it> (the "Documentation").

## 2\. Licence

**2.1** The CAT Software is available in various subscription plans. The functions, outputs and technical usage limits of each plan are described at appropriate online channels (the Portal, [www.justcat.it](http://www.justcat.it), the Documentation).

**2.2** Subject to these Terms and the Documentation, DT grants the User a non-exclusive, worldwide, non-transferable and non-sublicensable licence to install and use the CAT Software for the period during which the relevant plan is valid and available to the User (the "Licence").

**2.3** All plans may be used for commercial or non-commercial purposes and with test, development or production data. The CAT Software may be used on local devices, cloud infrastructure or third-party hosted environments that the User is authorised to use. A User may use CAT to provide services to third parties, provided that access to the CAT Software remains limited to properly licensed named individuals.

**2.4** Each Authorised User may install the CAT Software on more than one device, subject to the applicable plan limits and technical controls. Except where these Terms or the Documentation expressly prohibit an activity, the User may use the functionality made available by the CAT Software. Functionality exposed by error or obtained by circumvention does not expand the Licence.

## 3\. Accounts and Seats

**3.1** Particular subscription plans of CAT Software require an individual Portal account and sign-in. Account information must be accurate and kept up to date.

**3.2** A "Seat" is access for one named individual identified by an individual email address (i.e. **place in a paid subscription for one person)**. A Seat may not be assigned to a shared mailbox, service account, technical account or other non-personal identity, and sign-in credentials may not be shared.

**3.3** The Customer may assign a Seat to any individual it chooses, including a person outside the Customer's organization. The Customer remains responsible for the administration of its Seats and for use made under them.

**3.4** A freed Seat may be reassigned through the Portal only after the reassignment waiting period (cooldown) displayed in the Portal has expired.

**3.5** The User must protect passwords and other credentials, promptly notify DT of suspected compromise and must not permit another person to use an Account or Seat assigned to someone else.

## 4\. Interactive use only

**4.1** Particular subscription plan of CAT Software may permit interactive use only. Each run must be deliberately and manually started by a signed-in individual.

**4.2** An "Autonomous Run" is any unattended or automatically initiated run, including a run started by a scheduler, CI/CD pipeline, background service, service account, technical account or another automated process.

**4.3** The User must not bypass or interfere with authentication, licensing, plan limits, Seat controls, Autonomous Run detection or other technical protections. DT may use technical measures and telemetry to verify compliance, as described in its Privacy Policy.

## 5\. Online purchases through Paddle

**5.1** Online purchases of particular subscription plans of CAT Software are made from the relevant Paddle entity, which acts as DT's authorised reseller and merchant of record ("Paddle"). The applicable Paddle entity is determined by the Buyer's location under the Paddle Buyer Terms, i.e.

- United States: _Paddle.com Inc._ incorporated in the U.S. with registered office at 3811 Ditmars Blvd. #1071, Astoria, New York, NY 11105-1803, USA;
- Canada: _Paddle.com (Canada) Ltd_. incorporated in Canada with registered office at 22 Adelaide Street West, Suite 3400, Toronto, Ontario, M5H 4E3, Canada; and
- Rest of world: _Paddle.com Market Limited_ incorporated in England and Wales with company number 8172165 and registered office at 30 Old Bailey, London, United Kingdom, EC4M 7AU

**5.2** A paid online purchase creates two related agreements: (a) the transaction agreement between the Customer and Paddle under the [Paddle Buyer Terms](https://www.paddle.com/legal/buyer-terms) and the [Paddle Refund Policy](https://www.paddle.com/legal/refund-policy); and (b) the licence agreement between the User and DT under these Terms. For the Paddle Buyer Terms, DT is the "Supplier", the CAT Software is the "Product", and these Terms are the "Supplier Agreement".

**5.3** Paddle is responsible for checkout, charging and collecting the price, recurring billing, payment methods, sales taxes, transaction receipts and tax invoices, subscription administration, cancellations, refunds and statutory withdrawal rights relating to the transaction. DT is responsible for providing the Licence, making the CAT Software available and handling product-related support and defects. Paddle is not a party to these Terms, and DT is not a party to the Paddle Buyer Terms.

**5.4** Particular subscriptions are monthly or annual, as selected at checkout, and automatically renew for successive periods equal to the initial subscription period until cancelled. Paddle charges the payment method on file. The Customer may cancel through Paddle's buyer portal or support channels; cancellation takes effect at the end of the current paid billing period, access continues until then, and no further renewal is charged.

**5.5** Subscription price changes are notified before they apply and take effect from a renewal date. Consent will be obtained where required by law. If the Customer does not accept a price increase, it may cancel before renewal. Failed payments, suspected fraud, abusive chargebacks or termination of the Paddle transaction may result in suspension or termination of access.

**5.6** Refunds and consumer withdrawal requests for Paddle transactions must be submitted to Paddle and are governed by Paddle's Refund Policy and mandatory law. DT does not issue refunds directly for Paddle transactions. For a technical defect or failure to obtain access, the User should first contact DT so that DT can attempt a remedy and, where appropriate, support a refund request to Paddle. An approved refund may end access to the relevant plan.

## 6\. Intellectual property and restrictions

**6.1** DT and its licensors retain all intellectual property rights in the CAT Software, the Portal and the Documentation. The Licence grants only the rights expressly stated in these Terms. The User retains its rights in its data, projects, test definitions and outputs.

**6.2** The User must not: (a) distribute, sell, rent, lease, sublicense or make copies of the CAT Software available to another person, except for authorised Seat use; (b) publish or share credentials; (c) remove proprietary notices; (d) circumvent technical controls or use functionality outside the applicable plan; (e) introduce malware or interfere with the CAT Software or Portal; or (f) use the CAT Software unlawfully or in a manner that infringes third-party rights.

**6.3** The Licence does not include source code. The User must not reverse engineer, decompile or disassemble the CAT Software, except to the limited extent that applicable mandatory law expressly permits that activity and does not allow the restriction to be waived. Before relying on such an exception, the User must request any legally required interoperability information from DT.

**6.4** The User is responsible for having all rights, permissions and legal bases required to use and process the data made available to CAT, and for the security, lawful configuration and backup of its systems and data.

## 7\. CAT Pilot

**7.1** CAT Pilot is an optional AI assistant available in CAT Studio. It is disabled unless the User actively configures and uses it with the User's own account at a third-party AI provider.

**7.2** CAT Pilot communications are sent directly between the User's environment and the selected AI provider and do not pass through the Portal or DT's servers. The AI provider's own terms and privacy policy govern that relationship, and DT is not a party to it.

**7.3** The User decides what is sent through CAT Pilot. Prompts and conversations may contain project details, tests, SQL queries, data structures and real data. The User is solely responsible for having authority to send that content, for protecting confidential and personal data, and for complying with applicable law and third-party obligations.

**7.4** DT does not control or guarantee the functionality, availability, security, legality or outputs of a third-party AI provider. AI output may be incomplete, inaccurate or unsuitable and must be independently reviewed before use. To the maximum extent permitted by law, DT is not liable for loss arising from the User's choice or use of an AI provider or reliance on its output.

**7.5** DT's standard telemetry may record that CAT Pilot was used and technical details of its use, but not the content of the CAT Pilot conversation, as further described in DT's Privacy Policy.

## 8\. Updates, availability and conformity

**8.1** DT may modify the CAT Software to improve, secure, maintain or comply with law. A material adverse change to a paid plan will normally apply no earlier than the next renewal, unless an earlier change is reasonably required for security, legal or technical reasons. Mandatory consumer rights relating to modifications and updates remain unaffected.

**8.2** Except for rights that cannot be excluded, the CAT Software is supplied "as available". DT does not warrant uninterrupted or error-free operation, compatibility with every environment, or fitness for a purpose not expressly stated in the Documentation. No service level agreement applies unless agreed separately.

**8.3** A User who is a consumer retains all mandatory rights relating to the conformity of digital content and digital services. Nothing in these Terms limits those rights.

## 9\. Suspension and termination

**9.1** The Customer may stop using Starter at any time and may cancel a paid subscription as described in Section 5. Cancellation of a paid subscription does not ordinarily create a right to a refund for the unused part of the current billing period, except under Paddle's policies or mandatory law.

**9.2** DT may suspend or terminate access if the User materially or repeatedly breaches these Terms, uses CAT unlawfully, threatens security, circumvents plan controls, shares Accounts or Seats, fails to pay through Paddle, or if Paddle suspends or terminates the relevant transaction. Where appropriate, DT will give notice and a reasonable opportunity to remedy the breach; urgent action may be taken without prior notice to protect security, prevent fraud or comply with law.

**9.3** When the Licence ends, the User must stop using the affected paid functions and delete copies that it is no longer entitled to retain. Clauses intended by their nature to survive, including intellectual property, liability and final provisions, remain effective.

## 10\. Liability

**10.1** For a User acting in connection with its trade, business, craft or profession (a "Business User"), and to the maximum extent permitted by law, DT is not liable for indirect or consequential loss, loss of profit, revenue, savings, goodwill, business opportunity, business interruption, loss or corruption of data, third-party contractual penalties, fines or claims.

**10.2** To the maximum extent permissible, DT excludes liability for any harm caused to the User by defects of the CAT Software, in particular, DT's liability for direct and indirect damages, including lost profits, contractual penalties claimed by third parties against the User, fines or other penalties imposed by public authorities is excluded.

**10.3** To the maximum extent permissible, DT excludes liability for any harm caused to the User by use of the functionality "CAT Pilot" as it redirects to the AI provider chosen by the User without any influence of the DT. The User shall be solely responsible for handling the data provided the chosen AI assistant.

**10.4** Nothing in these Terms excludes or limits liability where exclusion or limitation is prohibited, including liability for fraud, intentional misconduct, gross negligence, injury to natural rights, or mandatory consumer rights. The exclusions and caps apply only to the extent permitted by applicable law.

**10.5** DT is not responsible for delay or failure caused by events outside its reasonable control, including internet, cloud, identity provider, payment provider or third-party AI service outages, provided that this does not limit any mandatory remedy.

## 11\. Privacy, complaints and final provisions

**11.1** DT processes personal data and telemetry as described in its Privacy Policy at <https://docs.justcat.it/privacy-policy>. Paddle independently processes transaction and billing data under its privacy notice at <https://www.paddle.com/legal/privacy>. The selected AI provider processes CAT Pilot data under its own privacy terms.

**11.2** Product, licence and technical complaints should be sent to DT at <hello@justcat.it>. Payment, invoice, tax, subscription, cancellation and refund requests relating to a Paddle transaction should be submitted to Paddle through the channels stated in the Paddle Buyer Terms and transaction email.

**11.3** DT may amend these Terms. DT will notify registered Users of a material amendment at least 30 days before it takes effect, unless an earlier change is required by law, security or to prevent abuse. Material adverse amendments to a paid plan will normally take effect at renewal. Continued use after the effective date constitutes acceptance to the extent permitted by law.

**11.4** These Terms and the relationship between DT and the User are governed by the laws of the Czech Republic, excluding its conflict-of-law rules. A consumer retains the protection of mandatory law of the country of habitual residence and may use the courts available under mandatory consumer jurisdiction rules. Business Users submit to the exclusive jurisdiction of the Czech courts, with local venue at DT's registered office where legally permitted. Paddle-related disputes are governed separately by the Paddle Buyer Terms.

**11.5** A consumer dispute with DT that cannot be resolved directly may be submitted to the Czech Trade Inspection Authority, Central Inspectorate - ADR Department, Gorazdova 1969/24, 120 00 Prague 2, Czech Republic, email <adr@coi.gov.cz>, <https://coi.gov.cz/informace-o-adr/>.

**11.6** All notices may be sent electronically to the email address associated with the Account. If any provision is invalid or unenforceable, the remaining provisions remain effective. A failure to enforce a right is not a waiver. These Terms, the applicable order and Documentation constitute the agreement on use of the CAT Software; the transaction with Paddle remains subject to the separate Paddle terms. The English version prevails to the extent permitted by mandatory law.
