LegrolCAD Terms of Service
Version 2.0 | Effective date: 4 October 2026
These Terms are also provided in Chinese. In the event of any discrepancy or conflict between the English and Chinese versions, the English version shall prevail (see clause 18.5).
Please read these Terms in full before using LegrolCAD (the "App"). By tapping "Agree and sign in" you confirm that you have read, understood and accepted these Terms and the Privacy Policy. If you do not agree, do not use the App.
1. Who provides the App
The App is provided by LEGROL SDN BHD, a private limited company incorporated under the laws of Malaysia ("we", "us", "our"). Contact: qbcalculator@gmail.com.
2. Definitions
- App: the LegrolCAD Android application and any subsequent versions.
- Drawings: DXF / DWG files that you create, open, edit or export with the App, and anything derived from them (including underlays and exported images and PDFs).
- Conversion Service: the server-side component used for DXF ↔ DWG format conversion, whose address and access token are entered by the user in the App's settings. The App does not bundle or pre-configure any Conversion Service.
3. Account and sign-in
3.1 The App requires you to sign in. You may sign in with a Google account or register an App account with an e-mail address.
3.2 You warrant that the information you provide when registering and signing in is true and accurate, and that you have reached the age at which you may independently enter into a contract in your jurisdiction (persons under 18 must use the App with the consent of a legal guardian; the App is not intended for persons under 13).
3.3 Your account is for your personal use only. You are responsible for safeguarding your password and device, and for all consequences of anyone else using your account. Notify us immediately if you discover unauthorised use of your account.
3.4 The number of accounts a single person may register is limited to a reasonable number. We may restrict or delete accounts created abusively or by automated bulk registration.
4. Licence and restrictions
4.1 We grant you a non-exclusive, non-transferable, revocable licence to install and use the App for your own purposes on devices owned or controlled by you or by the organisation to which you belong.
4.2 You must not:
- decompile, disassemble or reverse-engineer the App, or attempt to extract any key, token or algorithm from it (except for interoperability purposes expressly permitted by law);
- crack, circumvent or remove the App's sign-in, verification, licensing or copyright notices;
- copy, sell, rent, sub-license or redistribute the App or its installation package;
- make automated large-scale calls to the App or the services it depends on, or perform load testing, denial-of-service attacks or vulnerability scanning against them;
- use the App for unlawful activities, or upload or process third-party files that you have no right to process;
- impersonate any other person, or offer services to others in the App's name without our written permission.
4.3 The App includes third-party open-source components, which are provided under their respective licences. Those licences take precedence with respect to the component concerned.
5. Your Drawings and content
5.1 Your Drawings belong to you. We do not acquire any ownership of your Drawings.
5.2 By default, Drawings exist only on your device. You may also choose to upload Drawings to your own Google Drive. We do not store, back up or view the content of your Drawings.
5.3 When you use a Conversion Service, your Drawing is uploaded to the server address you have entered for format conversion. You are responsible for verifying the ownership and security of that server. The App acts solely as a transport channel and gives no endorsement or warranty as to the availability, security or legality of any Conversion Service that you configure yourself. We accept no liability for any data leakage, interception of network traffic, file corruption, service interruption or third-party infringement caused by such a server, whether deployed by you, your organisation or any third party. Only where a Conversion Service is operated by us and clearly identified as such within the App do we accept responsibility for it under these Terms. Details of the conversion process and data retention are set out in the Privacy Policy.
5.4 You are responsible for the content of the Drawings you process, including whether you have the right to process them and whether they contain confidential or personal data.
6. Third-party services
6.1 Google Sign-In, Google Drive, Firebase and similar services are provided by Google and are governed by Google's own terms of service and privacy policy. We have no control over the availability, quotas or policy changes of those services.
6.2 We are not liable where a change, throttling or termination of a third-party service makes a related feature of the App (such as cloud backup or sign-in) unavailable, but we will make reasonable efforts to inform you or to offer an alternative.
7. Format compatibility and professional judgement (important)
7.1 The reading and writing of DXF / DWG files, font substitution, dimension styles, and the rendering of blocks and hatches may differ from AutoCAD or other CAD software. The App is not AutoCAD and is not certified or endorsed by Autodesk. The App's support for the DXF / DWG formats is based solely on publicly available technical specifications and on open-source libraries used in compliance with their licences; the App has no official partnership, authorisation, affiliation or technical endorsement relationship with Autodesk, Inc.
7.2 Measurements, areas, coordinates and other values produced by the App are calculated from the drawing data and are for reference only.
7.3 You must not rely on the App's output as the sole basis for any decision concerning construction, structural, fire-safety, electrical, regulatory-approval or other matters involving personal or property safety. Before any formal use, verify the results with professional software and have them reviewed by a suitably qualified person.
8. Data and backup responsibility
8.1 We do not provide any backup or recovery service for your Drawings.
8.2 Uninstalling the App, clearing system storage, changing devices, revoking file permissions, or suspension of a third-party cloud account may all result in data loss. Backing up your data is your responsibility.
8.3 Local mechanisms such as auto-save and the pending-conversion queue are best-effort aids and do not constitute any promise that data will not be lost.
9. Provision, changes and termination of the service
9.1 New accounts may use the App free of charge for a trial period of three (3) days. After the trial period, continued use requires us to grant or extend a usage period for your account. When your usage period ends, you will not be able to use the App until it is renewed (Drawings stored on your own device and in your own Drive are not affected). You may notify us from within the App to request a renewal. We may at any time add, modify, suspend or discontinue the App or any of its features, including interrupting the service for maintenance, upgrade or security reasons.
9.2 To verify your usage period, the App needs to connect to the internet periodically. The App may be used offline for up to seven (7) consecutive days, after which it must connect to the internet once to verify before you can continue using it.
9.3 If you seriously or repeatedly breach these Terms, we may suspend or terminate your account without prior notice. After termination you retain access to the Drawings stored on your own device and in your own Drive.
9.4 You may stop using and uninstall the App at any time, and you may delete your account record from within the App.
10. Fees
10.1 The App does not currently charge fees within the App. Usage periods after the trial are granted by us to individual accounts; whether any fee is payable, and its amount, shall be agreed separately between you and us.
10.2 We reserve the right to charge, within the App, for usage periods or certain features in the future. Prices and scope will be clearly stated within the App and in these Terms at that time. Charges will not apply retrospectively to any usage period already granted to you.
11. Intellectual property
The App's code, user interface, name, logo, documentation and all intellectual property therein belong to LEGROL SDN BHD or its licensors. All rights not expressly granted in these Terms are reserved. DXF, DWG, AutoCAD and Autodesk are trademarks of Autodesk, Inc.; Google, Android, Google Drive and Firebase are trademarks of Google LLC; other names are trademarks of their respective owners. References to those marks in the App are made solely to describe format compatibility or the services relied upon, and do not imply any affiliation, sponsorship or endorsement.
12. Disclaimer of warranties
To the maximum extent permitted by law, the App is provided "as is" and "as available", without any warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, reliability, uninterrupted operation or freedom from error. You use the App entirely at your own risk.
13. Limitation of liability
13.1 To the maximum extent permitted by law, we shall not be liable for any loss of profits, business interruption, loss or corruption of data or Drawings, loss of goodwill, third-party claims, or any indirect, incidental, special, punitive or consequential damages, even if we have been advised of the possibility of such loss.
13.2 In no event shall our aggregate liability arising out of or in connection with these Terms or the App exceed the total amount you have actually paid to us for the App in the twelve (12) months preceding the event giving rise to the claim. If you have paid us nothing during that period (including where you use the free part of the App), that cap shall be fifty Malaysian Ringgit (RM 50).
13.3 Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain liabilities, so the above clauses apply to you only to the extent permitted by local law. Nothing in these Terms excludes liability that cannot be excluded by law (such as liability for wilful misconduct, gross negligence or personal injury).
14. Indemnity
You shall indemnify us and hold us harmless against all losses, costs and reasonable legal fees arising from any third-party claim, demand, regulatory investigation or proceeding caused by your breach of these Terms, your unlawful use of the App, or the content of the Drawings you process.
15. Force majeure
We are not liable for any failure or delay in performance caused by events beyond our reasonable control, including natural disasters, war, epidemics, government action, power or network outages, or failure of third-party services.
16. Changes to these Terms
16.1 We may revise these Terms. The revised version will be published on the Terms of Service page with its version number and effective date.
16.2 Material changes (for example the introduction of fees, an increase in the categories of data collected, or a change to the dispute-resolution mechanism) will require your renewed consent within the App; if you do not consent, you will not be able to continue using features that require sign-in. Non-material changes take effect upon publication, and your continued use constitutes acceptance.
16.3 We record in your account the version of the Terms you accepted and the time of acceptance, as evidence for both parties.
17. Governing law and dispute resolution
17.1 These Terms are governed by the laws of Malaysia, without regard to its conflict-of-laws rules.
17.2 The parties shall first attempt to resolve any dispute through good-faith negotiation. If negotiation fails, the dispute shall be submitted to the courts of Malaysia having jurisdiction.
17.3 To the extent permitted by law, you agree to bring claims only in your individual capacity and not to participate in any class action or class arbitration.
18. General
18.1 Severability: if any provision of these Terms is held invalid or unenforceable, the remaining provisions remain in full force.
18.2 No waiver: our failure or delay in exercising any right does not constitute a waiver of that right.
18.3 Entire agreement: these Terms together with the Privacy Policy constitute the entire agreement between you and us concerning the App and supersede all prior oral or written communications.
18.4 Assignment: you may not assign your rights or obligations under these Terms; we may assign these Terms in connection with a transfer or reorganisation of our business.
18.5 Language: these Terms are provided in English and in Chinese. In the event of any discrepancy or conflict between the two versions, the English version shall prevail; the Chinese version and any other translation are provided for convenience only.
