# 2. Licence grant

## 2.1 Core Edition

Subject to the terms of this Agreement, Telemity grants the Licensee a non-exclusive, non-transferable, worldwide licence to install and use the Core Edition on any number of Servers, including in commercial environments, free of charge, for the Licensee's own internal lawful business purposes.

## 2.2 Assured Edition

Subject to the terms of this Agreement and payment of the applicable Subscription fees, Telemity grants the Licensee a non-exclusive, non-transferable licence to install and use the Assured Edition on the number of Servers covered by the Licensee's active Subscription. This licence is valid for the duration of the Subscription and in the territories specified in the applicable order form.

## 2.3 Scope

Both licences granted under this clause 2 are licences to use the Software in object code form only. No source code licence is granted. Both licences are personal to the Licensee and may not be assigned, sublicensed, or transferred without Telemity's prior written consent.

# 3. Permitted uses

The Licensee may:

- (a) install and use the Software on its own infrastructure, whether on-premises or in a private cloud environment operated for the Licensee's own internal use;
- (b) use the Software alongside other software tools, platforms, or products;
- (c) publish factual benchmarks, technical evaluations, or reviews of the Software;
- (d) make a reasonable number of archival copies of the Software solely for backup purposes, provided that such copies are not distributed and retain all proprietary notices.

# 4. Restrictions

The Licensee must not, and must not permit any third party to:

- (a) redistribute, share, or make the Software available to any third party, whether for payment or free of charge, except as expressly permitted under this Agreement;
- (b) sublicense, resell, rent, lease, or otherwise transfer the Software or any rights in it;
- (c) offer the Software, or any service incorporating the Software, as a hosted, managed, or software-as-a-service offering to third parties;
- (d) reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the Software, except to the extent that such activity is expressly permitted by applicable law notwithstanding this restriction, and in that case only after giving Telemity prior written notice;
- (e) modify, adapt, or create derivative works based on the Software;
- (f) remove, alter, or obscure any proprietary notices, labels, or markings on or in the Software;
- (g) use the Software in any way that violates applicable law or regulation.

# 5. Assured Edition — subscription and licence compliance

## 5.1 Per-Server licensing

Each Server on which the Assured Edition is installed and operated requires a separate active Subscription. The Licensee must not install or operate the Assured Edition on more Servers than are covered by its current Subscription.

## 5.2 Verification

Telemity reserves the right to request written confirmation from the Licensee of the number of Servers on which the Assured Edition is deployed. The Licensee agrees to provide such confirmation within ten (10) business days of a written request from Telemity. Telemity may also verify compliance by technical means, including local validation of licence files, provided that any such verification does not transmit DNS telemetry, operational data, or configuration data to Telemity and does not unreasonably interfere with the Licensee's operations.

## 5.3 Subscription renewal

If a Subscription expires and is not renewed, the Licensee's right to use the Assured Edition terminates at the end of the Subscription period. The Licensee may continue to use the Core Edition, which remains available under clause 2.1.

## 5.4 Unpaid Assured features

Operating the Software with Assured Edition features enabled without a valid Subscription constitutes a material breach of this Agreement.

# 6. Intellectual property

## 6.1 Ownership

The Software and all intellectual property rights in it are and remain the exclusive property of Telemity. This Agreement does not transfer any ownership interest in the Software to the Licensee. The Licensee acquires only the limited licence rights expressly set out in this Agreement.

## 6.2 Feedback

If the Licensee provides Telemity with feedback, suggestions, or other input regarding the Software ("Feedback"), the Licensee grants Telemity a perpetual, irrevocable, royalty-free, worldwide licence to use that Feedback for any purpose, including incorporating it into the Software, without obligation or restriction.

## 6.3 Public suffix list data

The Software may incorporate or make use of data from the Mozilla Public Suffix List (https://publicsuffix.org
). The Public Suffix List is maintained by Mozilla contributors and made available under the Mozilla Public License 2.0.

# 7. Support

## 7.1 Core Edition

Telemity will use reasonable endeavours to respond to support enquiries from Core Edition users submitted by email to the address published at telemity.com. Support for the Core Edition is provided on a best-effort basis. Telemity does not guarantee any specific response time and is under no obligation to provide fixes, patches, or updates.

## 7.2 Assured Edition

Telemity will provide support to Assured Edition subscribers through the channels specified in the applicable order form or Subscription confirmation, which may include email, telephone, and a support portal. Telemity will target the response times set out in the Subscription documentation. These are target response times and do not constitute guaranteed service levels or contractual service level agreements unless separately agreed in writing.

## 7.3 No obligation to update

Nothing in this Agreement obliges Telemity to develop or release updates, new versions, or patches to the Software, whether for security vulnerabilities or otherwise.

## 7.4 Security updates

Telemity may, at its discretion, release updates, patches, or mitigations addressing security vulnerabilities or operational issues in the Software. Nothing in this Agreement obliges Telemity to provide any such updates unless separately agreed in writing.

# 8. Data and privacy

## 8.1 Data stays with the Licensee

The Software is designed to operate entirely within the Licensee's own infrastructure. The Software does not transmit DNS telemetry data, configuration data, or any other operational data to Telemity or to any third-party service operated or controlled by Telemity.

The Licensee is solely responsible for ensuring that its collection, processing, and transmission of DNS telemetry data using the Software complies with all applicable data protection and privacy laws, including without limitation the UK General Data Protection Regulation, the Data Protection Act 2018, and any equivalent legislation applicable in the Licensee's jurisdiction.
