SIRIUS LIDAR — TERMS OF USE AND SUBSCRIPTION LICENSE AGREEMENT

Version 1.0 — sold through Paddle on siriuslidar.com — 9 October 2026. English translation for reference; the Portuguese version prevails (clause 13.4).

LICENSOR: SIRIUS SOLUÇÕES GEOESPACIAIS INOVA SIMPLES (I.S.), CNPJ 68.164.899/0001-11, with registered office at Avenida Doutor João Batista Soares de Queiroz Júnior, 120, apto. 93, Edifício Araruama, Jardim das Indústrias, São José dos Campos/SP, CEP 12240-000, Brazil, e-mail contato@siriuslidar.com (“Sirius”).

LICENSEE: the individual or company that subscribes and installs the program (“User”).

These terms are shown before purchase on siriuslidar.com and must be expressly accepted by the User at the time of purchase and on the acceptance screen shown when installing the Program. The User may keep a copy of these terms at any time.

1. Purpose

1.1. Sirius grants the User, while the subscription is active and paid, a license to use the computer program Sirius LiDAR (the “Program”), under Brazilian Law No. 9,609/1998. The license is non-exclusive and non-transferable. The license key, the purchase receipt and the acceptance of these terms prove the regular use of the Program (Law No. 9,609/1998, art. 9). 1.2. Each subscription allows use on 1 (one) computer at a time. The User may move the license to another computer of their own with the “Release this PC” function. 1.3. During the subscription, the User receives all published updates of the Program. Updates may change features but keep the essential purpose contracted. 1.4. The Program, its code, trademarks and documentation remain the property of Sirius. 1.5. Sirius declares that it holds the rights to the Program, or is licensed for its third-party components, and is liable to the User if a third party claims, with grounds, that the regular use of the Program under these terms infringes copyright.

2. Purchase, payment and reseller

2.1. Our order process is conducted by our online reseller Paddle.com (Paddle.com Market Limited, United Kingdom). Paddle.com is the Merchant of Record for all our orders. Paddle processes the payment, issues the invoice, calculates and collects taxes, charges renewals and provides all customer service inquiries related to payments and handles returns. 2.2. The purchase is a contract between the User and Paddle, governed by Paddle’s buyer terms (Paddle Buyer Terms). The license to use the Program is a contract between the User and Sirius, governed by these terms. This division of tasks does not remove Sirius’s liability towards the consumer under the Brazilian Consumer Protection Code (CDC). 2.3. If these terms and the reseller’s terms conflict on refunds, withdrawal or cancellation, the rule more favorable to the User prevails. 2.4. The Program is not offered to consumers resident in the European Economic Area or the United Kingdom. If a consumer from those regions nevertheless subscribes, the mandatory rules of their country apply, including longer withdrawal periods.

3. Plans, price and automatic renewal

3.1. Plans: weekly (7 days), monthly and yearly, at the prices published on siriuslidar.com at the time of purchase, charged in US dollars (US$) or in the local currency shown on the payment page (including Brazilian reais, R$, for buyers in Brazil), with the taxes of the buyer’s country included or added as required by local law. The amount debited in another currency may vary with the exchange rate and taxes applied by the card issuer; the price only changes under clause 3.4. In some countries the bank may require additional authentication for renewals. 3.2. Automatic renewal. The subscription renews automatically at the end of each period (7 days, 1 month or 1 year), at the current price and charged to the same payment method, until the User cancels. The User expressly agrees to this when confirming the purchase, after seeing it shown prominently next to the price and billing period. The receipt of each charge is sent by e-mail and shows the amount and the link to manage or cancel the subscription. 3.3. Renewal notice. For monthly and yearly plans, Sirius sends an e-mail, directly or through the reseller, about 7 (seven) days before each renewal, with the charge date. 3.4. Price changes. The price of a period already paid never changes. Any new price only applies from a renewal that occurs at least 30 (thirty) days after the e-mail notice, which states the new amount, the date it takes effect and how to cancel at no cost. If the User does not cancel before the renewal, the subscription continues at the new price. 3.5. Failed payment. If a renewal charge fails, the User is notified by e-mail and the reseller retries for up to about 14 (fourteen) days. During this time the Program keeps working. If payment is not settled, the subscription ends and the license is suspended, with no penalty and no retroactive charge. The User may subscribe again at any time.

4. Cancellation

4.1. The User may cancel at any time, with no penalty and no reason: (a) through the “Manage subscription” link included in the purchase e-mail and in every receipt (Paddle’s customer portal); or (b) by e-mail to contato@siriuslidar.com. We send the cancellation confirmation by e-mail. Cancellation applies to future charges from the moment it is requested, regardless of any notice period in the reseller’s terms; any amount charged after the cancellation request is fully refunded. 4.2. After cancellation, the Program keeps working until the end of the period already paid. After that, the license expires. 4.3. Outside the right of withdrawal (clause 5) and the cases in the Refund and Cancellation Policy, there is no pro-rata refund of the current period.

5. Right of withdrawal

5.1. On the first purchase of any plan, the User may withdraw within 7 (seven) days of purchase and immediately receives a full, updated refund of the amount paid (CDC, art. 49). 5.2. On a yearly renewal, the same 7-day period counts from the date of the renewal charge. 5.3. Withdrawal may be requested through the same channel used for the purchase (by replying to the receipt e-mail) or by e-mail to contato@siriuslidar.com. Details are in the Refund and Cancellation Policy.

6. License activation

6.1. The Program is activated with the license key sent by Sirius by e-mail after payment is confirmed. Activation and periodic checks require an internet connection. 6.2. Without a connection, the Program keeps working for up to 14 (fourteen) days (monthly and yearly plans) or 2 (two) days (weekly plan), counted from the last successful check. 6.3. Activation and checks send to Sirius’s license server only the license key and a pseudonymous technical identifier of the computer (generated from hardware data, without the computer name or the content of the User’s files), as described in the Privacy Policy. 6.4. If the check does not happen within the period of clause 6.2, the Program is locked until the next successful check. The User’s files remain intact and accessible with other programs. 6.5. The license may be deactivated: (a) at the end of a subscription that is not renewed; (b) in case of refund, withdrawal or payment dispute (chargeback); (c) in case of fraudulent use, sharing of the license key or circumvention of the license system, with notice by e-mail stating the reason. In other cases of breach, deactivation requires 10 (ten) days’ prior notice to remedy.

7. Technical validity period and support (Law No. 9,609/1998, arts. 7 and 8)

7.1. The technical validity period of the licensed version is the period of the active, paid subscription. During this period, validity covers the latest published version of the Program and the immediately previous version, until 60 (sixty) days after the new version is published. 7.2. During the technical validity period, Sirius provides, at no extra cost, remote technical support by e-mail (contato@siriuslidar.com) on the proper operation of the Program, according to its published specifications and minimum requirements (including Windows 10 or 11, 64-bit). The first reply is given within 2 (two) business days, and Sirius fixes or works around reproducible errors within a reasonable time. Support does not include training, processing of the User’s data or engineering consultancy. 7.3. If Sirius discontinues the Program, it will notify the User by e-mail at least 60 (sixty) days in advance and will either keep the Program and support working until the end of the period already paid or refund the unused period pro rata (art. 8, sole paragraph).

8. Restrictions

The User may not: (a) copy the Program, except for installation and one backup copy (Law No. 9,609/1998, art. 6, I); (b) sell, rent, lend, sublicense, assign or distribute the Program or the license key, or share it with third parties; (c) modify, decompile, disassemble or reverse-engineer the Program, except for the acts allowed by art. 6 of Law No. 9,609/1998 and the rights granted by the licenses of the open-source components (clause 12); (d) remove copyright notices or circumvent, disable or falsify the license and activation system. Unauthorized use or reproduction subjects the infringer to the civil and criminal penalties of Law No. 9,609/1998.

9. Technical nature of the results and User responsibility

9.1. The Program is a support tool that automates steps of point cloud processing. Automatic classifications, digital terrain models, contour lines, profiles, sections and other products are generated by algorithms whose accuracy depends on the quality, density, reference system and parameters of the input data and on the settings chosen by the User. These products may contain errors. 9.2. Before being used in projects, reports, surveys, technical documents or deliverables to third parties, the results must be checked and validated by a legally qualified professional, who takes the corresponding technical responsibility (for example, through an ART before the CONFEA/CREA system, Law No. 6,496/1977, or the equivalent document of the relevant professional body). 9.3. The Program does not replace professional judgement, field surveys or the applicable technical standards. 9.4. The User alone is responsible for: (a) checking, validating and approving all results before any use, comparing them with control points, field checks or other independent means; (b) choosing and checking the processing parameters, classes, horizontal reference system, vertical datum, geoid model and transformations applied; (c) ensuring the quality, integrity and suitability of the input data (point clouds, centerlines, layers, orthophotos and control points); (d) complying with the technical standards and the legal and contractual requirements applicable to their work (for example ABNT NBR 13133 or the standards of DNIT, INVIAS or the contracting party); and (e) obtaining the authorizations needed for the surveys and for the use of the data. 9.5. Known limitations. The User acknowledges that: (a) automatic and machine-learning classification may assign points to the wrong class; (b) in areas without ground points (for example under buildings, dense vegetation, water or vehicles) the digital terrain model and the contour lines are interpolated and are not measurements; (c) the accuracy of the adjustment to control points depends on the number, distribution and quality of those points; and (d) transformations between reference systems depend on the grids and parameters chosen. 9.6. Except for defects of the Program itself, Sirius is not liable for incorrect measurements, elevations, volumes, areas, alignments, designs, reports or decisions resulting from the input data, the parameters chosen, the limitations described in clause 9.5 or the lack of verification of the results by the User. 9.7. The Program was not designed to be the sole source of information for decisions involving risk to life, to the safety of structures or people, or to the environment. In such cases, the results must be verified by independent means before any decision. 9.8. This clause does not remove Sirius’s liability for defects of the Program itself, as set out in clause 10.

10. Liability

10.1. When the User is a consumer, Sirius is liable for defects of the Program under the Brazilian Consumer Protection Code, without the limitations of clause 10.2, except as provided in art. 51, I, of the CDC for corporate consumers. 10.2. When the User, an individual or a company, uses the Program in their professional or business activity, Sirius’s total liability for damages arising from the Program or these terms is limited to the greater of (i) the total paid by the User in the 12 (twelve) months before the event and (ii) R$ 1,500.00 (one thousand five hundred Brazilian reais). Sirius is not liable for loss of profits, loss of business or indirect damages. The parties acknowledge that this limitation is justified by the subscription price, the support-tool nature of the Program (clause 9), the User’s ability to check the results and the exclusively local processing of data (Brazilian Civil Code, arts. 421 and 421-A; CDC, art. 51, I, where applicable). 10.3. The limitation does not apply to willful misconduct or gross negligence, to damage to life or physical integrity, to infringement of third-party intellectual property rights by Sirius, to personal data incidents or to other cases in which the law forbids limitation. 10.4. System requirements and equipment. Point cloud processing makes intensive use of the processor, memory and disk, sometimes for hours. The User is responsible for using the Program on a computer that meets the minimum and recommended requirements published on siriuslidar.com, with free disk space, adequate cooling and power supply (a UPS is recommended), and an operating system, drivers and antivirus kept in working order. 10.5. Except for defects of the Program itself, Sirius is not liable for failures, slowness, freezes, overheating, shutdowns, data loss or damage to the computer, the operating system or other programs resulting from: (a) use on equipment below the requirements or in inadequate conditions; (b) hardware defects, wear or lack of maintenance; (c) power outages or fluctuations; (d) viruses, malware, antivirus, drivers or other third-party programs; or (e) changes to the Program made by the User or third parties. Use of the processor, memory and disk within the equipment’s capacity is part of the normal operation of the Program. 10.6. Backups. The User alone is responsible for keeping backup copies of their input data and results before and after each processing. The Program writes results to the folders chosen by the User and may overwrite files with the same name in those folders. Except for defects of the Program itself, Sirius is not liable for data loss resulting from the lack of backups, interrupted processing, lack of disk space or the User’s choice of folders and file names. 10.7. Third-party data and rights. The User declares that they have the rights and authorizations needed for the data they process (point clouds, orthophotos, centerlines, layers and client data) and is solely responsible for keeping that data confidential and for sharing it with third parties. 10.8. Third-party programs. Features that depend on programs installed by the User, such as QGIS (for ECW orthophotos) and the ODA File Converter (for DWG), are governed by the licenses of those programs. Sirius does not guarantee the operation, availability or future compatibility of those programs. 10.9. Except for the legal warranty under the Brazilian Consumer Protection Code, Sirius does not guarantee that the Program will run uninterrupted or error-free, or that it will meet specific needs not described on siriuslidar.com. 10.10. When the User uses the Program in their professional or business activity, they undertake to hold Sirius harmless from claims by third parties (such as their clients or contracting parties) arising from the use of unverified results or from the User’s breach of these terms, except for defects of the Program itself.

11. Personal data

The Program processes point clouds and results only on the User’s computer. The data processed for the purchase and the license are described in the Privacy Policy.

12. Third-party components

12.1. The Program includes open-source components (including PDAL, GDAL, PROJ, NumPy, SciPy, scikit-learn and laspy), licensed by their authors under their own licenses (for example BSD, MIT and Apache 2.0). The copyright notices and license texts are in the THIRD_PARTY_NOTICES file installed with the Program. 12.2. For those components, the rights their licenses grant to the User prevail, and nothing in these terms restricts them. 12.3. The warranty disclaimers of those licenses protect the authors of the components and do not reduce Sirius’s obligations to the User under these terms and the law.

13. Termination, governing law and jurisdiction

13.1. The license ends: (a) at the end of a subscription that is not renewed; (b) on refund or exercise of the right of withdrawal; (c) for serious breach of these terms (clause 8), subject to clause 6.5. The end of the license does not affect the files generated by the User, which remain theirs, nor clauses 9, 10 and 13, which survive termination. 13.2. These terms are governed by the laws of Brazil. The choice of Brazilian law does not deprive the consumer of the protection of the mandatory rules of their country of habitual residence. 13.3. For consumers, the competent court is that of their domicile (CDC, art. 101, I), without prejudice to others the law allows them. In other cases, the courts of São José dos Campos/SP, Brazil. 13.4. These terms are written in Portuguese. Translations are for reference; in case of divergence, the interpretation more favorable to the consumer prevails. 13.5. Sirius may assign these terms to a successor company or a company of the same group, with notice to the User and without prejudice to their rights.
