1.1. This instrument ("Terms") governs the contractual relationship between STLFLIX PRODUTOS DIGITAIS LTDA, a private legal entity enrolled with the Brazilian company registry (CNPJ) under no. 43.939.351/0001-75, headquartered at Rua Jerônimo Coelho, 78 - Centro, Joinville/SC, Brazil, and the user ("USER") who accesses, uses, or purchases any plan or service made available by the Platform.

1.2. The USER irrevocably and unconditionally represents that they have read, understood and fully accept these Terms upon performing any of the acts below, whichever occurs first:

a. Completing payment for the contracted plan, regardless of the payment method (credit card, PIX, bank slip, or any other means);

b. Logging into the restricted area of the Platform for the first time using a username and password;

c. Using any feature of the Platform, even partially;

d. Clicking a confirmation button, checkbox, link, or any other electronic acceptance mechanism made available during the purchase or onboarding flow.

1.3. Electronic acceptance is equivalent, for all legal purposes, to the USER’s signature, pursuant to Article 107 of the Brazilian Civil Code, Provisional Measure No. 2.200-2/2001, and Law No. 14.063/2020. The record of access, payment, and use constitutes full proof of acceptance.

1.4. If the USER does not agree with any provision of these Terms, the USER must refrain from purchasing or using the Platform.

2.1. For the purposes of this instrument, the following definitions apply:

"Platform": software exclusively owned by STLFLIX, intended to provide digital files of three-dimensional models for 3D printing.

"User": the person who has purchased the services and/or products made available on the STLFLIX Platform.

“Materials”: three-dimensional models, digital files, graphic elements, drawings, designs, images, content, code, features, and other items made available by STLFLIX through the Platform.

“License to Use”: means the limited, personal, non-exclusive, non-transferable, and revocable authorization granted by STLFLIX to the USER, for the duration of the contracted plan and for as long as the USER remains in good standing, to use the Materials exclusively under the conditions and for the purposes expressly set forth in these Terms of Use, without implying any assignment, transfer, or acquisition of any intellectual property or copyright over the Materials.

3.1. Registration for access to the Platform is carried out by the USER at the time of purchase and will only take effect after payment has been approved.

3.2. Access to the Platform’s restricted area is for the USER’s exclusive, personal use, and the USER is prohibited from sharing their credentials.

3.3. The USER is solely responsible for safeguarding their access credentials (username and password), and sharing them with third parties is prohibited. STLFLIX will not be held liable for unauthorized access resulting from the USER’s negligence in safeguarding their credentials.

3.4. The USER undertakes to provide truthful, complete, and up-to-date information at the time of registration and throughout the use of the Platform, and is responsible for the accuracy of the information provided and for any losses resulting from incorrect, incomplete, or outdated information.

3.5. The USER must immediately notify STLFLIX of any suspected unauthorized access, loss, compromise, or misuse of their credentials, so that reasonably necessary measures can be taken to protect the account and the Platform.

4.1. For the duration of the contracted plan and for as long as the USER remains in good standing with all payment obligations, the Platform grants the USER a limited, personal, non-exclusive, non-transferable, and revocable License to Use, exclusively to use the digital files made available on the Platform for the purpose of physically printing, on a 3D printer, the respective three-dimensional models, for personal or commercial use.

4.2. The License to Use granted to the USER also covers the images of printed products made available on the Platform, authorizing their use exclusively for the purpose of promoting, advertising, and marketing the respective physical products on the e-commerce platforms and marketplaces used by the USER, and their use for any purpose other than that provided for in this clause is prohibited.

4.3. The license provided for in this clause is granted exclusively for the purpose of printing the three-dimensional models, and the USER is prohibited from doing the following, except with the prior express authorization of the Platform and/or the respective rights holder, as applicable:

a. distributing, making available, sharing, transmitting, publishing, or otherwise providing the digital files, in whole or in part, to third parties;

b. assigning, sublicensing, transferring, or allowing third parties to access the digital files;

c. marketing, reselling, licensing, or monetizing the digital files, whether on their own or incorporated into any other product or service;

d. making the digital files available on websites, platforms, marketplaces, social networks, groups, communities, repositories, or any other means of sharing or distribution;

e. reproducing, modifying, adapting, editing, converting, decompiling, disassembling, or creating derivative works from the digital files, when such acts exceed the use strictly necessary for authorized printing;

f. using the digital files for any purpose other than the physical printing of the three-dimensional models, including developing, manufacturing, marketing, or economically exploiting other files, models, or derivative products, when not expressly authorized; and

g. engaging in any other conduct that involves exploiting, making available, or using the digital files in a manner inconsistent with the specific purpose of the license granted in this clause.

4.4. The license will remain valid only while the contracted plan is in effect and the USER is in good standing with the respective payment obligations. Suspension, cancellation, termination, or rescission of the plan, as well as the USER’s default, will result in the immediate termination of the license to use, regardless of prior notice, except where applicable law provides otherwise.

4.5. Once the license has ended, the USER must immediately stop using the digital files made available by the Platform, including new downloads and prints, and must delete or render unusable any copies of the files in their possession or control.

4.6. Failure to comply with the restrictions set forth in this clause may result, without prejudice to the other measures provided for in these Terms of Use and applicable law, in the suspension or termination of the USER’s account, revocation of the license, and the adoption of appropriate measures to protect the intellectual property rights of the respective rights holders.

4.7. The USER may hire third parties exclusively to physically perform the printing service for the licensed three-dimensional models, provided that such hiring is at the USER’s own expense and responsibility and is limited to carrying out the requested print. The hired third party will not acquire any License to Use or right over the Materials and may not store, reuse, share, market, sublicense, or otherwise exploit the respective digital files for any purpose other than performing the service contracted by the USER, and must delete any copies in their possession after the print is completed.

4.8. The temporary sharing of a digital file with a third party under the conditions set forth in the previous clause does not authorize its use for the benefit of the service provider or of the service provider’s other clients, and the USER remains responsible for ensuring that the third party complies with the limitations set forth in these Terms.

4.9. The catalog of Materials made available on the Platform is dynamic in nature and may be periodically expanded, updated, reorganized, or modified by STLFLIX, including through the addition, replacement, or removal of files, based on technical, commercial, creative, or intellectual property criteria, without this implying any guarantee of the permanent availability of any specific Material throughout the entire term of the plan.

4.10. Changes to the catalog may not result in a substantial and unjustified reduction of the core service contracted, or in a failure to honor a specific offer expressly made to the USER.

5.1. All Materials made available by STLFLIX constitute the intellectual property of STLFLIX, which also holds all copyright and other related economic and moral rights, with ownership remaining fully with STLFLIX.

5.2. Purchasing any plan, product, or service offered by STLFLIX, as well as accessing, downloading, or using the files made available on the Platform, does not constitute a sale, assignment, transfer, disposal, or any other form of transmission of intellectual property or copyright over the three-dimensional models or the respective digital files.

5.3. The license to use granted to the USER to print the Materials does not grant the USER any right of ownership, title, or exploitation over the digital files or over the intellectual property rights related to the three-dimensional models, and is strictly limited to the right to use the files during the term of the license and for the purpose set forth in this clause.

5.4. Violation of the intellectual property and copyright rights related to the Materials may result in the suspension or termination of the USER’s account and the revocation of the license granted, without prejudice to any administrative or judicial measures and the violator’s liability for any resulting losses and damages.

5.5. The License to Use granted by STLFLIX does not authorize the USER to use the Materials in a manner that infringes trademarks, trade names, image rights, copyrights, industrial designs, or any other third-party rights that may be associated with, inserted into, or combined by the USER with the physical products made from the Materials, and it is the USER’s sole responsibility to verify the legality of such uses.

6.1. Access to the Platform will be made available upon purchase of one of the plans or commercial offers made available by STLFLIX, the features, functionalities, term, price, and payment conditions of which will be disclosed to the USER prior to completing the purchase.

6.2. As of the last update of these Terms, STLFLIX offers the plans called “Comercial Mensal” (Commercial Monthly), “Comercial Anual” (Commercial Annual), and “Lote Especial” (Special Bundle), without prejudice to the creation, modification, or discontinuation of plans and commercial conditions for future purchases, subject to the conditions applicable to periods already contracted.

6.3. The Commercial Monthly plan has a monthly term with recurring billing, automatically renewing for successive periods unless the USER requests cancellation, as set forth in these Terms.

6.4. The Commercial Annual plan has a 12 (twelve) month term. When an installment payment option is offered for the respective price, including by credit card, the installment plan is exclusively a method of paying the total price corresponding to the annual term contracted, and does not characterize independent monthly fees or separate contracts with a monthly term.

6.5. The offer called “Lote Especial” (Special Bundle) will remain in effect according to the specific commercial condition presented at the time of purchase, automatically renewing at the end of the contracted period unless the USER requests cancellation. The USER will be notified by e-mail about the renewal close to the end of the current period.

6.6. The Commercial Monthly and Commercial Annual plans will automatically renew at the end of each term, for an equal period, unless the USER requests cancellation before the respective renewal date, subject to applicable law.

6.7. Automatic renewal will result in a new charge according to the price and conditions applicable to the renewal, which will be disclosed to the USER through the means made available by STLFLIX. Cancellation requested before renewal will prevent charges for subsequent periods, without affecting access corresponding to the period already contracted and paid for.

6.8. A request to cancel a future renewal does not imply early termination of the contract period in progress, nor does it exempt the USER from paying installments related to the price of the annual plan already contracted.

7.1. Right of Withdrawal

7.1.1. In cases characterized as a consumer relationship, where Article 49 of the Brazilian Consumer Defense Code applies, the USER may exercise the right of withdrawal within 7 (seven) calendar days of the purchase, by submitting a request through the channels made available by STLFLIX.

7.1.2. The regular exercise of the right of withdrawal within the period set forth in this clause will result in cancellation of the purchase and full reimbursement of amounts paid, subject to the means and procedures applicable to the payment method used.

7.1.3. Upon receiving a withdrawal request, STLFLIX will immediately take the steps necessary to reimburse or refund the amounts paid and, for transactions made by credit card or through a financial institution, will forward the request to the respective payment provider, with the actual availability of the credit subject to the operational procedures of the institution responsible.

7.2. Cancellation After the Legal Withdrawal Period

7.2.1. Once the legal withdrawal period has elapsed, the USER’s unjustified withdrawal will not entitle the USER to a full or proportional refund of amounts corresponding to the contract period already begun, nor, in the case of an annual plan purchased in installments, to cancellation of outstanding installments that make up the total price of the contracted period, except in cases expressly provided for in these Terms or under applicable law.

7.2.2. For the recurring monthly plan, cancellation requested after the legal withdrawal period will take effect for subsequent periods, preventing further renewal and billing, while access to the Platform will remain available until the end of the monthly period already contracted.

7.2.3. For the annual plan, any request to cancel renewal will prevent the purchase of a new annual period, but will not result in early termination of the current period, cancellation of remaining installments, or a proportional refund for any unused period, except in cases provided for by law or expressly set forth in these Terms.

7.2.4. STLFLIX offers plans with different terms, and longer-term plans may have different pricing conditions due to the commitment undertaken by the USER throughout the contracted period.

7.3. Exceptions and Grounds for Termination

7.3.1. Only the following grounds authorize contract termination with a proportional refund after the withdrawal period: (i) permanent discontinuation of the Platform by STLFLIX, with at least 30 (thirty) days’ prior notice to the USER; or (ii) a serious, proven, and persistent technical failure (lasting more than 10 consecutive days) that prevents the Platform from being available, due solely and attributably to STLFLIX, excluding operational impact caused by third-party tools or cases of force majeure.

7.3.2. The following do NOT constitute grounds for termination with a refund:

a. Dissatisfaction with Platform features that conform to what was contracted;

b. A unilateral decision not to use the plan, Materials, and other applications and services already made available;

c. Comparison with competing platforms or a subjective perception of inadequate cost-benefit.

8.1. STLFLIX may make additional digital applications, features, and services available on the Platform, in addition to the contracted plan, which may, as applicable, require a specific purchase or additional charge, with prior notice to the USER.

8.2. Additional applications, features, and services may be subject to specific conditions, which will form part of these Terms to the extent applicable to the respective purchase.

8.3. Purchasing an additional feature or service will not expand the License to Use the Materials, unless expressly provided for in the respective offer.

8.4. The features, availability, and commercial conditions of additional features and services may vary according to the offer in effect at the time of purchase.

9.1. Without prejudice to the other restrictions set forth in these Terms, the USER is prohibited from:

a. sharing, assigning, lending, selling, or allowing third parties to use their access credentials;

b. creating or using additional accounts, whether their own or belonging to third parties, for the purpose of circumventing technical, commercial, or security limitations of the Platform;

c. using bots, robots, crawlers, scripts, software, automation, or any other mechanisms intended to collect, scrape, index, extract, copy, or automatically or massively download the Materials or information from the Platform;

d. performing downloads in a volume or pattern inconsistent with regular personal use of the account, particularly when there are indications of systematic extraction or the building of a file archive;

e. accessing or attempting to access areas, accounts, systems, servers, or information for which they do not have authorization;

f. interfering with, compromising, improperly testing, or exploiting vulnerabilities in the Platform, its systems, servers, or security mechanisms;

g. introducing, transmitting, or spreading malware, viruses, malicious code, or any technology intended to compromise the integrity or operation of the Platform;

h. removing, hiding, or tampering with trademarks, identifiers, intellectual property notices, metadata, or protection mechanisms present in the Materials;

i. using the Platform or the Materials to commit fraud, an unlawful act, or to violate the rights of STLFLIX or third parties;

j. engaging in any act intended to circumvent access, download, licensing, or security restrictions technically implemented by STLFLIX.

9.2. The Materials may not be used, in whole or in part, to train, feed, fine-tune, improve, validate, or develop artificial intelligence models, generative systems, three-dimensional generation algorithms, training bases, datasets, or similar technologies, nor may they be made available to third parties for such purposes, except with STLFLIX’s prior express authorization.

9.3. STLFLIX may adopt reasonable technical limits on downloads, requests, simultaneous access, or resource usage, when necessary for Platform security, fraud prevention, containment of automation, protection of intellectual property, or preservation of service stability.

9.4. Any limits inherent to the contracted commercial plan that ordinarily affect the amount of downloads or features available to the USER will be disclosed prior to purchase. Temporary security measures adopted in response to abnormal or suspicious behavior will not be considered a change to the contracted plan.

9.5. STLFLIX may preventively suspend, in whole or in part, access to the account, downloads, or certain features when it identifies reasonable indications of credential sharing, automation, massive file extraction, fraud, intellectual property infringement, an attempted unauthorized access, a threat to Platform security, or any other conduct potentially contrary to these Terms.

9.6. The preventive suspension is precautionary in nature and may remain in place for the period reasonably necessary to investigate the occurrence. If the violation is confirmed, STLFLIX may maintain the restrictions, suspend or permanently terminate the account, and revoke the License to Use, without prejudice to any applicable administrative or judicial measures.

9.7. If the investigation shows that no irregularity is attributable to the USER, access will be restored as soon as technically possible.

10.1. STLFLIX will make reasonable efforts to keep the Platform regularly available, without, however, guaranteeing uninterrupted, continuous, or entirely error-free operation.

10.2. Temporary unavailability may occur due to scheduled or emergency maintenance, updates, hosting services, content distribution networks, third-party infrastructure, internet failures, cyberattacks, force majeure, or other circumstances beyond STLFLIX’s reasonable control, and occasional interruptions compatible with the nature of the service will not constitute a breach of contract.

10.3. STLFLIX’s financial liability, under any circumstances, is limited to the total amount actually paid by the USER for the term of the plan in effect.

10.4. STLFLIX does not guarantee the USER any economic, commercial, or professional result arising from the use of the Platform or the Materials, including sales volume, revenue, profit margin, return on investment, building or retaining a customer base, ad performance, approval, reach, or marketplace ranking, or any other results arising from the USER’s activities.

10.5. The decision to produce, advertise, price, and sell physical products printed from the Materials is the USER’s sole responsibility, and the USER must assess their own costs, production capacity, market, competition, tax obligations, and other circumstances related to their activity.

10.6. STLFLIX is not liable for indirect or consequential damages that do not directly result from an act attributable to STLFLIX, subject to the limitations permitted under applicable law.

10.7. STLFLIX is not liable for amounts invested by the USER in equipment, infrastructure, hiring staff, or any other costs incurred based on expectations of results.

10.8. Results obtained from the Materials may vary depending on the 3D printer used, slicing software, firmware, settings, calibration, material used, environmental conditions, operator experience, and other technical factors beyond STLFLIX’s control.

10.9. STLFLIX does not guarantee universal compatibility of the Materials with all 3D printers, software, versions, materials, equipment, or configurations on the market, and it is the USER’s responsibility to verify the requirements and conditions suitable for the intended print in advance.

10.10. Any recommendations regarding parameters, materials, settings, or procedures made available by STLFLIX are for guidance purposes only and may require adjustments depending on each USER’s equipment and specific conditions.

10.11. The USER is fully responsible for verifying the suitability, strength, safety, sizing, and compatibility of the physical product obtained from the Materials for the purpose for which the USER intends to use or sell it.

10.12. Unless a Material is expressly made available by STLFLIX for a specific purpose, the models should not be presumed suitable for structural, mechanical, electrical, medical, food-related, children’s, personal protective, or any other applications where failure could pose a significant risk to life, health, physical safety, or property, and it is the USER’s responsibility to carry out the relevant technical checks before using or selling the models.

11.1. Late payment of any amount owed to STLFLIX may result in, without prejudice to applicable late-payment charges:

a. after 10 (ten) days of delay, suspension of the right to make new downloads of the Materials;

b. after 20 (twenty) days of delay, suspension of access to the restricted area and the features linked to the contracted plan;

c. after 30 (thirty) days of delay, STLFLIX may consider the contract to be in default, terminate the plan, revoke the License to Use, and take appropriate collection measures.

11.2. Amounts past due may be subject to a late-payment penalty of 2% (two percent), late-payment interest of 1% (one percent) per month, calculated proportionally to the days of delay, and monetary correction based on the IPCA/IBGE index, or any index that may legally replace it.

11.3. Suspension of access due to default attributable to the USER will not result in reimbursement of amounts already paid, compensation for the suspension period, or automatic extension of the contract term.

11.4. Once all overdue amounts and related charges have been fully settled, STLFLIX will restore access within the technically reasonable time required after payment is confirmed.

11.5. STLFLIX may refer overdue debts for collection and to credit protection agencies, subject to the requirements and procedures set forth in applicable law.

12.1. STLFLIX will process the USER’s personal data in accordance with Law No. 13.709/2018 - the Brazilian General Data Protection Law (“LGPD”), observing the principles and legal bases applicable to each processing operation.

12.2. Personal data may be processed, as applicable, to create and maintain the registration, authenticate and secure the account, perform these Terms, make the contracted features available, process and collect payments, prevent fraud, provide customer support to the USER, comply with legal or regulatory obligations, exercise rights, and protect credit.

12.3. Processing may be based, depending on the purpose and applicable circumstances, on the performance of a contract, compliance with a legal or regulatory obligation, the regular exercise of rights, legitimate interest, credit protection, consent, or other legally provided grounds.

12.4. Additional information about the data processed, its purposes, sharing, retention periods, cookies, data subject rights, and channels for exercising them is available in STLFLIX’s Privacy Policy, which supplements these Terms.

13.1. STLFLIX reserves the right to change these Terms at any time, with 5 (five) days’ prior notice sent to the USER’s registered e-mail address. Continued use of the Platform or payment of any installment after this period has elapsed will constitute tacit and irrevocable acceptance of the new conditions.

14.1. The parties undertake to seek an amicable resolution of any disagreement through direct communication or, if necessary, out-of-court mediation.

14.2. If an amicable resolution is not possible, the courts of the Joinville district, in the State of Santa Catarina, Brazil, are elected as the sole venue to settle any matters arising from these Terms, with the parties expressly waiving any other venue, however privileged it may be.

15.1. If any clause of these Terms is deemed null, invalid, or ineffective by a court or administrative decision, the remaining clauses will remain in full force and effect, and the invalid clause will be replaced by the applicable legal provision closest to the parties’ original intent.

15.2. Tolerance or the failure to exercise any right provided for in these Terms will not constitute a waiver, novation, or precedent for future requirements.

15.3. These Terms constitute the entire agreement between the parties regarding the subject matter described herein, superseding any prior understandings or agreements, whether verbal or written.
