Terms of use
Last updated: August 2026
1. Acceptance of these terms
These Terms of Use (“Terms”) form a binding agreement between you and the operators of Hardlock5 (“Hardlock5,” “we,” “us,” or “our”) governing access to and use of hardlock5.com, the Hardlock5 application, APIs, and related services (collectively, the “Service”). By accessing or using the Service—including public verification without an account—you agree to these Terms and to our Privacy notice. If you do not agree, do not use the Service. If you use the Service on behalf of an organization, you represent that you have authority to bind that organization, and “you” includes that organization.
2. The Service
Hardlock5 provides tools to (a) certify origin of images, short video, and documents using neural watermarks and cryptographic certificates anchored on Klever Blockchain, and (b) verify media against those records. The Service is technical infrastructure for origin attestation. It is not a law firm, notary, court, deepfake detector, fact-checker, or content-moderation authority. We may modify, suspend, or discontinue features, capacity, SLAs, or regions at any time. We have no obligation to support any particular file format, transform, or third-party platform indefinitely.
3. Eligibility
You must be at least 18 years old (or the age of majority in your jurisdiction, if higher) and legally capable of entering contracts. You may not use the Service if you are barred under applicable sanctions, export, or anti-abuse laws, or if we have previously suspended your access.
4. Issuer accounts and security
Issuer features require an account. You must provide accurate registration data, keep credentials and multi-factor methods secure, and promptly notify us of unauthorized access. You are solely responsible for all activity under your account, team seats you invite, API keys, and any signing keys or secrets under your control—including loss, theft, or compromise of those materials. We may require email verification, KYC/KYB checks, or additional verification before enabling features. We are not responsible for losses arising from compromised credentials or keys you control.
5. Public verification
Anyone may submit a file for public verification without an account. You represent that you have all rights necessary to upload and process that file. Results describe technical origin signals only (for example watermark recovery, certificate status, fingerprint distance). Results do not establish that depicted content is true, complete, newsworthy, non-defamatory, non-infringing, or lawful. Offline or degraded modes may only indicate watermark presence without proving authenticity. Always read on-screen honest limitations.
6. Your content and warranties
You retain ownership of media and metadata you upload (“Your Content”), subject to licenses you grant us. You represent and warrant that: (a) you own Your Content or have all licenses and consents needed to use it with the Service; (b) Your Content and your use of the Service do not violate law, third-party rights (including privacy, publicity, copyright, trademark, trade secret), contracts, or court orders; (c) you will not upload malware or content intended solely to disrupt the Service; and (d) certifications you issue are not knowingly false or misleading as to origin under your control. You grant us a worldwide, non-exclusive, royalty-free license to host, copy, process, transmit, display, and create technical derivatives of Your Content solely to operate, secure, improve, and support the Service, comply with law, and enforce these Terms.
7. Acceptable use
You will not, and will not permit others to: (a) violate law or third-party rights; (b) forge, falsify, spoof, or misrepresent certificates, watermarks, issuers, or verification outcomes; (c) reverse engineer, decompile, or circumvent security, rate limits, or access controls except to the limited extent mandatory law forbids this restriction; (d) probe, scan, or test vulnerabilities without our prior written consent; (e) interfere with or overload the Service; (f) scrape or harvest data at scale for competing products without permission; (g) use the Service to distribute malware, spam, or illegal content; (h) resell or white-label the Service without a written agreement; or (i) misrepresent affiliation with Hardlock5, Klever, or ogxo.ai. We may investigate and take any action we deem appropriate, including suspension, content removal (off-chain), reporting to authorities, and cooperation with law enforcement.
8. Our intellectual property
The Service, software, models, documentation, UI, trademarks, and branding are owned by us or our licensors and are protected by law. Except for the limited right to use the Service under these Terms, no rights are granted. You will not remove proprietary notices. Feedback you provide may be used by us without restriction or compensation.
9. Fees, credits, and taxes
Some features require paid credits or subscriptions. Prices, packages, and limits may change. Fees are generally non-refundable except where mandatory consumer law requires otherwise or we expressly agree in writing. You are responsible for applicable taxes. Failed payments, chargebacks, or abuse may result in suspension. Unused credits may expire as stated at purchase or in the product UI.
10. Disclaimers of warranties
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, QUIET ENJOYMENT, OR ARISING FROM COURSE OF DEALING. WE DO NOT WARRANT THAT: (A) THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE; (B) WATERMARKS WILL SURVIVE ALL TRANSFORMS, RE-ENCODINGS, OR ATTACKS; (C) FINGERPRINT OR VERDICT THRESHOLDS ARE CORRECT FOR EVERY USE CASE; (D) VERIFICATION RESULTS ARE ADMISSIBLE EVIDENCE OR ESTABLISH TRUTH OF CONTENT; OR (E) ON-CHAIN DATA WILL BE AVAILABLE FROM ANY PARTICULAR NODE OR EXPLORER. SOME JURISDICTIONS DO NOT ALLOW CERTAIN DISCLAIMERS; IN THOSE CASES, DISCLAIMERS APPLY TO THE FULLEST EXTENT PERMITTED.
11. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, HARDLOCK5, ITS AFFILIATES, AND THEIR DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, SUPPLIERS, AND LICENSORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES; OR FOR LOSS OF PROFITS, REVENUE, DATA, GOODWILL, BUSINESS OPPORTUNITY, OR COST OF SUBSTITUTE SERVICES; OR FOR SERVICE INTERRUPTION—EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US FOR THE SERVICE IN THE THREE (3) MONTHS IMMEDIATELY BEFORE THE EVENT GIVING RISE TO LIABILITY, OR (B) USD 100 (OR EQUIVALENT). IF YOU USED ONLY FREE FEATURES (INCLUDING PUBLIC VERIFICATION), OUR AGGREGATE LIABILITY WILL NOT EXCEED USD 100. THESE LIMITATIONS APPLY REGARDLESS OF THEORY OF LIABILITY (CONTRACT, TORT, STRICT LIABILITY, OR OTHERWISE) AND FORM AN ESSENTIAL BASIS OF THE BARGAIN. NOTHING IN THESE TERMS EXCLUDES LIABILITY THAT CANNOT BE EXCLUDED UNDER MANDATORY LAW (FOR EXAMPLE, FRAUD OR WILLFUL MISCONDUCT WHERE SUCH EXCLUSION IS VOID).
12. Indemnification
You will defend, indemnify, and hold harmless Hardlock5, its affiliates, and their directors, officers, employees, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) Your Content; (b) your use or misuse of the Service; (c) your breach of these Terms or of law; (d) your infringement or violation of third-party rights; (e) certifications or statements you issue using the Service; or (f) disputes between you and third parties concerning media origin, authenticity narratives, or campaign/communications use of results. We may assume exclusive defense at your expense; you will cooperate fully.
13. Blockchain and public records
Certificate-related data anchored on Klever Blockchain is public, timestamped, and designed to be durable. Network fees, congestion, forks, reorgs, node availability, and explorer accuracy are outside our exclusive control. On-chain data may remain publicly visible after off-chain deletion or account closure. You acknowledge that blockchain publication is irreversible for practical purposes and that we cannot guarantee erasure of public chain history.
14. Third-party services
The Service may rely on third parties (identity providers, hosting, object storage, email, payment processors, blockchain networks, and explorers). Those services are governed by their own terms. We are not responsible for third-party outages, acts, or omissions, except to the extent mandatory law requires otherwise.
15. Suspension and termination
We may suspend or terminate access immediately, with or without notice, if we reasonably believe you breached these Terms, create risk or legal exposure, fail to pay, or if required by law. You may stop using the Service at any time. Provisions that by nature should survive (including ownership, licenses granted for operated period, disclaimers, liability limits, indemnity, governing law) survive termination. We may retain data as described in the Privacy notice and as required for legal compliance, security, and dispute resolution.
16. Export, sanctions, and anti-abuse
You will comply with applicable export control, sanctions, and anti-money-laundering laws. You will not use the Service in or for the benefit of sanctioned persons, regions, or prohibited end uses where restricted by law applicable to you or to us.
17. Governing law and disputes
These Terms are governed by the laws of the Federative Republic of Brazil, without regard to conflict-of-law rules that would require another jurisdiction’s law. Subject to mandatory consumer rights that cannot be waived, the courts of the City of São Paulo, State of São Paulo, Brazil, have exclusive jurisdiction over disputes arising out of or relating to these Terms or the Service. If mandatory law gives you the right to bring claims in your place of residence, that right remains unaffected. Before filing a claim, you agree to attempt good-faith resolution by contacting us and allowing thirty (30) days to respond.
18. General
These Terms, together with the Privacy notice and any order or plan terms shown at purchase, are the entire agreement between you and us regarding the Service and supersede prior or contemporaneous agreements on that subject. If any provision is held unenforceable, it will be modified to the minimum extent necessary, and the remainder will remain in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our prior written consent; we may assign them in connection with a merger, acquisition, corporate reorganization, or sale of assets. Notices may be provided via the Service, email, or by updating these pages. Headings are for convenience only. The English version of these Terms may be provided for convenience; if a Portuguese version is offered and there is a conflict for users in Brazil, the Portuguese version controls for those users to the extent required by law.
19. Changes to these Terms
We may update these Terms from time to time. We will revise the “Last updated” date and may provide additional notice for material changes when required. Continued use of the Service after the effective date of updated Terms constitutes acceptance, except where mandatory law requires express consent. If you do not agree, you must stop using the Service.
