End-User License Agreement (EULA)

Revision Date: October 11, 2026

Version: 2026-10-11. This revision accompanies releases that present it for acceptance. Existing purchases retain their applicable terms unless a change is lawfully notified and accepted where required.

Important: Please read this End-User License Agreement carefully before downloading, installing, purchasing, accessing, or using the Software or related Tweakrix services. This End-User License Agreement (“EULA”) is a legal agreement between you (either an individual or a single entity) and TERSISOFT LABS LTD, a company registered in the Republic of Cyprus under number HE 495617 (“Licensor”, “we”, “us”). This EULA governs your use of the Tweakrix software product(s) identified above, related websites, and associated software services, which may include related software components, media, printed materials, electronic documentation, and online functionality (collectively, the “SOFTWARE PRODUCT” or “Software”). Tweakrix is a brand of the Licensor.

You accept this EULA by selecting the agreement option presented during installation or another express acceptance step that identifies these terms. Downloading the installer alone does not authorize recurring charges or provide consent to optional analytics or advertising. If you do not accept, do not complete installation or use the Software. This EULA governs the Software license together with the applicable order terms and policies; it does not override mandatory rights or binding pre-contract information.

The SOFTWARE PRODUCT is protected by copyright laws and international copyright treaties, as well as other intellectual property laws and treaties. The SOFTWARE PRODUCT is licensed, not sold.

This EULA applies to software products developed and distributed by the Licensor under the Tweakrix brand, including but not limited to:

  • Tweakrix Driver Updater
  • other software utilities published under the Tweakrix brand

The Software is distributed via tweakrix.com and/or authorized distribution channels.

The Licensor is an independent software provider and is not affiliated with or endorsed by Microsoft Corporation or any hardware manufacturer.

1. INTRODUCTION

1.1 Acceptance and Consent

Express acceptance of this EULA forms the Software license agreement with TERSISOFT LABS LTD. Subscription authorization, requests for immediate paid performance, and optional data-processing consent are separate decisions. Accepting this EULA does not by itself waive any right to cancel or withdraw.

1.2 Eligibility

By using the Software, you represent that you are legally capable of entering into this agreement. If you accept this EULA on behalf of a company or other legal entity, you represent that you are authorized to bind that entity to this EULA.

1.3 Minors

By downloading, installing, or using the Software, you represent that you are of legal age to enter into this EULA under the laws applicable to you, or that you have obtained valid consent from a parent or legal guardian.

1.4 Updates to this EULA

We identify each revision by date and version. Material changes will be communicated before they apply, with notice and renewed acceptance where required by law. A website update alone does not retrospectively change an existing purchase or remove accrued rights. You may retain a copy of the terms presented to you.

2. DEFINITIONS

2.1 “Software” or “SOFTWARE PRODUCT”

Means the Tweakrix software product identified above, including executable files, components, updates, accompanying documentation, and related materials supplied by the Licensor.

2.2 “Documentation”

Means user-facing explanatory materials, website product descriptions, help content, and other written or electronic materials relating to the Software.

2.3 “Updates”

Means patches, bug fixes, compatibility changes, or new releases of the Tweakrix application supplied by the Licensor. Third-party device drivers and their updates are separate materials governed by the relevant manufacturer or other rights holder’s license.

3. SCOPE AND APPLICABILITY

3.1 Products in Scope

This EULA applies to software products developed and distributed by the Licensor, including but not limited to Tweakrix Driver Updater and other software utilities published under the Tweakrix brand, unless separate license terms are expressly provided for a specific product.

3.2 Distribution Channels

The Software may be distributed via tweakrix.com and/or authorized distribution channels.

3.3 Business Users and Authorization

If you accept this EULA on behalf of a business, organization, educational institution, government body, or other legal entity, you represent and warrant that you have the authority to bind that entity to this EULA. That entity is responsible for ensuring that its employees, contractors, and authorized users comply with this EULA.

3.4 Language

This version is in English. Mandatory local language requirements take precedence, including any requirement to provide a French version before offering a choice of language in Quebec. Where law permits and you expressly choose English after receiving any required local-language version, English governs inconsistencies. This clause is not a waiver of language rights.

4. LICENSE GRANT

4.1 License

Subject to this EULA and payment for any paid features, the Licensor grants you a personal, non-transferable, non-exclusive, limited license to install and use the Software during the applicable license term. Suspension or termination is governed by Section 9 and mandatory law; the license is not arbitrarily revocable during a paid term.

4.2 Installation and Use

Your paid plan determines the number of computers on which you may activate and use the SOFTWARE PRODUCT at the same time. Tweakrix Driver Updater Lite covers one computer; Standard covers up to five computers. Each computer must run a validly licensed, supported Microsoft Windows operating system. Free scanning does not require a paid activation.

4.3 Single User

The license is for the purchaser’s use within the computer limit of the purchased plan. You may not share the license key with unrelated users or exceed the plan’s simultaneous computer limit. You can release an old computer through the email-verified device-management flow before activating a replacement computer.

4.4 Backup Copies

You may make copies of the SOFTWARE PRODUCT as reasonably necessary for backup and archival purposes.

4.5 Reservation of Rights

The Licensor reserves all rights not expressly granted to you under this EULA.

5. RESTRICTIONS

(a) Maintenance of Copyright Notices

You must not remove or alter any copyright notices on any and all copies of the SOFTWARE PRODUCT.

(b) Distribution

You may not distribute registered copies of the SOFTWARE PRODUCT to third parties. If evaluation/trial versions are made available for download from Tweakrix websites, such evaluation versions may be distributed only in unmodified form.

(c) Prohibition on Reverse Engineering, Decompilation, and Disassembly

You may not reverse engineer, decompile, or disassemble the SOFTWARE PRODUCT, except and only to the extent that such activity is expressly permitted by applicable law notwithstanding this limitation.

(d) Usage Restrictions

You may not rent, lease, lend, resell, or sub-license the SOFTWARE PRODUCT. You may not circumvent any technical protection measures in the Software.

(e) Compliance with Applicable Laws

You must comply with all applicable laws regarding use of the SOFTWARE PRODUCT.

(f) No Unauthorized Access for Third Parties

You may not provide, share, sublicense, or otherwise make the Software available to any other person except as expressly permitted by this EULA.

6. PRIVACY, DATA COLLECTION, AND THIRD-PARTY SERVICES

6.1 Privacy and Data Collection

The Privacy Policy explains what data is processed, for which purposes, on which legal bases, and how to exercise your rights. Accepting this EULA acknowledges that notice; it does not constitute consent to optional analytics or advertising. Where consent is required, it is requested separately and may be withdrawn through the available controls. Declining optional tracking does not authorize us to withhold purchased core functionality. Data needed to provide the service or meet legal obligations is handled as explained in the Privacy Policy.

6.2 Third-Party Services and Components

Third-party drivers, components, services, and websites remain subject to their own applicable licenses and terms. This EULA licenses Tweakrix; it does not replace, expand, or grant redistribution rights under a manufacturer’s driver license. Applicable license conditions and notices must be respected regardless of whether a file comes directly from a manufacturer, through a proxy, or from another permitted source. Payment for Tweakrix does not purchase driver files or third-party licenses. Our own obligations and mandatory consumer rights are not transferred to a third party by this clause.

6.3 Scope of Functionality

The Software provides functionality as described on the official Tweakrix website or within the Software interface. The Software is not a substitute for professional services and does not provide guarantees of system performance, security, or error-free operation unless explicitly stated.

6.4 Availability and Third-Party Dependencies

Features may depend on third-party sources and infrastructure, and particular driver versions may become unavailable. We cannot promise that every device has a newer compatible driver. We remain responsible for our own contractual and statutory obligations, including applicable remedies if the paid service does not conform to its description.

7. SUBSCRIPTIONS, PRICING, AND PAYMENTS

7.1 Free and Paid Functionality

Tweakrix Driver Updater provides free scanning and review of available update information. A paid subscription covers Tweakrix software features for finding compatible updates and automatically installing the updates you select and confirm, within your plan’s device limit. The subscription does not purchase driver files or third-party driver licenses. Free results do not imply that every detected item is defective, unsafe, or requires a paid update. We do not guarantee a performance improvement or a newer driver for every device.

7.2 Seller, Price, and Order Information

For current website subscriptions, Creem (Armitage Labs OÜ) acts as Merchant of Record and handles payment, invoices, and applicable indirect taxes. TERSISOFT LABS LTD provides the Software and product support. The checkout identifies the seller, currency, billed total, taxes, plan, device limit, billing interval, introductory price if any, and renewal price. Review the final order and applicable Creem Buyer Terms before authorizing payment. We do not collect or store full payment card details. If a different authorized sales channel is used, its seller and payment arrangements must be disclosed before purchase.

7.3 Renewal and Cancellation

Monthly, six-month, and yearly subscriptions renew at the disclosed interval and renewal price until cancelled, where you expressly authorize recurring billing and it is permitted by applicable law. An introductory price applies only for its stated period. Renewal notices and notice or consent for price changes will be provided where required. No recurring charge is authorized merely by downloading or accepting this EULA.

You can manage or cancel renewal through the Creem Customer Portal at https://www.creem.io/portal or the subscription-management link supplied with your order. Contact support@tweakrix.com if you cannot access that route. Cancellation stops future renewals according to the applicable order and mandatory law; paid access normally continues until the end of the paid period. Any right to earlier termination or a refund is preserved. Uninstalling the Software does not itself cancel the subscription. Keep your order confirmation and cancellation confirmation.

7.4 Refunds, Withdrawal, and Faulty Services

The Refund Policy describes our commercial refund offer and how to request it. That offer is additional to mandatory rights and does not impose a deadline on statutory claims for defective or non-conforming Software or services. A refusal of a change-of-mind refund does not decide whether a statutory remedy is due.

Where a cooling-off or withdrawal right applies, starting digital supply affects that right only if the applicable legal requirements, including any separate express request, consent, acknowledgement, and confirmation, are met. Accepting this EULA, downloading the free installer, or activating alone is not a blanket waiver. The order flow must explain any effect of immediate performance before you request it. Contact support@tweakrix.com or the disclosed Merchant of Record for billing and remedy requests; their procedures do not reduce mandatory rights.

8. UPDATES AND NEW RELEASES

8.1

We may provide application Updates and will provide updates necessary to meet applicable contractual and statutory obligations, including required security and conformity updates. This is separate from the availability of third-party driver releases.

8.2

Where an Update or new release is provided by the Licensor: (a) you may be required to install the Update or new release to continue using the Software; and
(b) you may be required to accept a new license agreement for the Update or new release. If no new EULA is supplied, this EULA shall continue to apply to the Update or new release.

8.3

We may make reasonable changes for security, legal compliance, compatibility, or service maintenance. Material changes affecting purchased functionality will be notified as required by law. We will not use a change to avoid an existing paid commitment; applicable rights to continued conformity, termination, price reduction, or refund remain available. Urgent protective measures may be taken without advance notice where necessary, with an explanation when practicable.

8.4

Changes do not exclude our responsibility under Sections 11, 12, and 17 or mandatory law. No promise is made that an individual third-party driver source will remain available indefinitely.

9. TERMINATION

9.1 Termination by the Licensor

We may suspend or terminate the license for a material breach, unlawful use, or a genuine security risk. Where practicable and appropriate, we will explain the reason and allow a reasonable opportunity to remedy a breach. Immediate action may be necessary to prevent harm or comply with law. Termination does not remove accrued refund, remedy, or consumer rights and does not itself determine subscription billing obligations.

9.2 Effect of Termination

Upon termination, you must cease using the Software and destroy all copies of the SOFTWARE PRODUCT in your possession or control, unless applicable law requires otherwise.

9.3 Survival

The provisions relating to intellectual property, warranties, limitation of liability, indemnification, payment obligations, governing law, and any provisions which by their nature should survive termination shall remain in effect after termination of this EULA.

10.1

All title, including but not limited to copyrights, in and to the SOFTWARE PRODUCT, the Tweakrix brand, the related Website, documentation, and any copies thereof, is owned by TERSISOFT LABS LTD. All title and intellectual property rights in and to third-party content that may be accessed through the SOFTWARE PRODUCT remain the property of the respective content owners and may be protected by applicable copyright or other intellectual property laws and treaties. Any permission to use third-party content comes from its applicable license or law, not from ownership of a Tweakrix subscription. Those permissions and any required notices remain effective on their own terms; restrictions in this EULA do not override rights granted by third-party or open-source licenses.

10.2

You acknowledge that the Software and documentation are protected by intellectual property rights (the “Rights”). You must not, during or after termination of this EULA, permit any act that infringes those Rights.

For avoidance of doubt, this EULA does not grant you any right to use any trademarks of Tweakrix associated with the Software or documentation.

11. WARRANTIES

11.1 Product Commitments and Technical Risk

We will supply the Software and paid service in accordance with their agreed description and applicable law. Driver installation can cause incompatibility, instability, or data loss; review selections and maintain appropriate backups before making system changes. No promise is made that every issue will be resolved or that speed, reliability, or security will improve. These risk explanations do not exclude statutory guarantees, required reasonable care and skill, or our responsibility for a failure to meet them.

Except for express commitments and warranties or guarantees that cannot lawfully be excluded, no additional warranty of uninterrupted operation or universal compatibility is provided.

11.2 Pre-Contract Information

Nothing in this EULA excludes reliance on binding product descriptions, express promises, or pre-contract information protected by applicable law. No acknowledgement of independent judgment waives those protections.

11.3 Compatibility and Environment

The Software may not be compatible with all hardware, devices, driver packages, operating systems, system configurations, security tools, or third-party applications. You are responsible for ensuring that your device environment is suitable for the Software and for reviewing system requirements, detected devices, and available update information before making changes.

11.4 Geographic and Language Availability

The Software, related services, support options, pricing, billing flows, or certain features may not be available in all countries, regions, or languages. The Licensor makes no warranty that all features or services will be available in your location.

11.5 User Representations

You represent and warrant that: (a) any information you provide to the Licensor or its payment/service partners is accurate and current; (b) you will use the Software only on devices you own or are authorized to manage; (c) you will use the Software in compliance with applicable law and third-party rights; and (d) you will review update selections and make your own technical decisions before installing any driver updates or related changes.

12. LIABILITY

Nothing in this EULA excludes or limits liability for fraud, fraudulent misrepresentation, death or personal injury caused by negligence, intentional wrongdoing, or any other liability, warranty, guarantee, or remedy that cannot lawfully be excluded or limited. Section 17 takes precedence over conflicting limitations.

For consumers, we are responsible for losses for which applicable law makes us liable, including foreseeable loss caused by our breach where that is the relevant legal standard. No contractual monetary cap under this EULA applies to consumer claims. We are not responsible for a loss to the extent it is caused solely by your misuse or circumstances for which the law does not make us responsible.

For business users only, to the extent permitted by applicable law and subject to the first paragraph, we exclude indirect or consequential business losses and our aggregate liability under this EULA is limited to the fees paid for the Software in the twelve months preceding the event giving rise to the claim. This business limitation does not override any applicable non-excludable protection.

13. THIRD-PARTY CLAIMS

Consumers are not required by this EULA to indemnify us or pay our legal costs for using the Software. For business users only, to the extent permitted by law, you are responsible for third-party claims directly caused by your unlawful use or knowing infringement of third-party rights. This does not cover a claim caused by our breach or wrongdoing. We must promptly notify you and reasonably cooperate in any defence; no settlement admitting liability or imposing obligations on you may be made without your agreement.

14. EXPORT COMPLIANCE

You may not use the Software in violation of export control laws. You represent and warrant that you are not located in, under the control of, or a national or resident of any country to which the export of the Software is prohibited by applicable law.

15. GENERAL PROVISIONS

15.1 Severability

If any provision of this EULA is held to be invalid, illegal, or unenforceable, this EULA shall otherwise remain in full force and effect, and the invalid provision shall be deemed modified to the minimum extent necessary to make it enforceable.

15.2 Non-Waiver

Failure by the Licensor to enforce any right or provision of this EULA shall not constitute a waiver of such right or provision.

15.3 Assignment

You may not assign or transfer this EULA or any rights granted under it without prior written consent from the Licensor. The Licensor may assign this EULA in connection with a merger, acquisition, corporate reorganization, or sale of assets.

15.4 Force Majeure

Where events outside our reasonable control affect supply, we will take reasonable steps to mitigate their impact and inform affected customers when practicable. This does not remove mandatory consumer remedies or a right to terminate for prolonged failure to supply.

15.5 Governing Law and Jurisdiction

Cyprus law governs this EULA, subject to mandatory protections that apply in your country, state, province, or territory of habitual residence. A consumer retains any right to bring a claim in local competent courts and to use applicable complaint or dispute-resolution procedures. Cyprus courts have exclusive jurisdiction only for business disputes where legally permitted. No mandatory arbitration, class-action waiver, or waiver of access to a regulator is imposed by this EULA.

17. MANDATORY LOCAL CONSUMER RIGHTS

17.1 All Markets

If you purchase as a consumer, mandatory local rights prevail over this EULA, order terms, and our commercial Refund Policy. Depending on applicable law, these may include conformity, quality, safety, reasonable care and skill, security updates, repair, replacement, repeat performance, price reduction, cancellation, refund, and compensation. You do not need to accept a new agreement to retain those rights. References below are not an exhaustive list, a claim that every market is supported, or a substitute for required local disclosures and languages.

17.2 European Union and EEA, Including Ireland

Applicable national rules for digital content and services and distance contracts remain effective. These include conformity and applicable update obligations, remedies for non-conformity, and withdrawal rights subject to the lawful conditions for immediate performance. For Ireland, rights under the Consumer Rights Act 2022 are preserved. Commercial refund time limits do not shorten statutory claims.

17.3 United Kingdom

Applicable rights under the Consumer Rights Act 2015 and distance-contract rules remain effective, including digital-content quality, fitness and description requirements, service obligations, and applicable remedies. Nothing excludes liability for damage to devices or other digital content where the law requires a remedy. Withdrawal rights are affected by immediate performance only where the applicable legal conditions are met.

17.4 Australia

Our goods and services come with guarantees that cannot be excluded under the Australian Consumer Law. Applicable rights concerning acceptable quality, fitness for purpose, description, due care and skill, and remedies for failures are preserved. Depending on the type and seriousness of the failure, the law may entitle you to repair, replacement, cancellation, refund, or compensation for reasonably foreseeable loss. These rights are not limited to our commercial refund period or by any liability cap in this EULA.

17.5 New Zealand

Applicable guarantees and remedies under the Consumer Guarantees Act 1993 and protections under the Fair Trading Act 1986 are preserved, including quality, fitness for purpose, reasonable care and skill, and remedies for failures. We do not contract out of those protections for consumer purchases.

17.6 Canada

Applicable federal, provincial, and territorial protections remain effective, including statutory warranties, required distance-contract information, cancellation rights, renewal rules, and language rights where applicable. Quebec protections are not waived by a choice of Cyprus law, a liability limitation, or an English-language preference. Any required French contract and related disclosures must be provided before an alternative language is expressly chosen. This English version alone does not establish compliance with those operational requirements.

17.7 United States

Applicable federal and state consumer protections remain effective. Recurring billing requires the disclosures, consent, cancellation mechanism, and notices required by applicable law. Warranty and remedy rules vary by state; exclusions do not apply where prohibited. This EULA imposes no mandatory arbitration or class-action waiver and does not create a nationwide statutory cooling-off period where none applies.

17.8 Other and Future Markets

The same preservation of mandatory rights applies in other markets. Availability in a new market does not dispense with required local-language terms, disclosures, billing controls, taxes, or remedies. The terms presented with your order identify the service you are buying; this EULA does not promise worldwide availability.
