This End User Licence Agreement ("Agreement") is a binding contract between you ("you") and QuantaFin Lab [Inc. | LLC], a Wyoming [corporation | limited liability company] with its registered office at [address] ("QuantaFin", "we", "us").
It governs your installation and use of the Blokduck software, including the desktop application, the command line interface, any server or on-premise deployment, and the application programming interface (together, the "Software").
By installing, copying, or using the Software, or by clicking to accept this Agreement, you agree to be bound by it. If you do not agree, do not install or use the Software.
If you are accepting on behalf of an organisation, you confirm you have authority to bind that organisation, and "you" means that organisation.
"Document" means a single file submitted to the Software for processing.
"Protected Copy" means the output file the Software produces from a Document.
"Blok" means an individual item of content that the Software identifies and obscures within a Protected Copy.
"Seat" means one named individual authorised to use the Software under a paid plan. A Seat is a person, not a device; one individual may install the Software on more than one machine for their own use.
"Free Plan", "Small Business Plan" and "Enterprise Plan" mean the plans described at blokduck.com/pricing, as updated from time to time. "Trial Period" means the three months described in section 3.1. "Licence Key" means the signed key file we issue, recording your Plan, validity period, grace period, and Document Allowance. "Document Allowance" means the number of Documents your Licence Key authorises the Software to process in a period.
"Your Content" means any Document you submit to the Software and any Protected Copy produced from it.
Subject to your compliance with this Agreement, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use the Software as follows.
You may install and use the Software free of charge, with full functionality and no Document limit, for three (3) months from your first use, for any lawful purpose. The Trial Period is granted once per individual and once per organisation; reinstalling, changing machine, or resetting local state does not restart it. When it ends you must install a valid Licence Key to process new Documents.
For your personal, non-commercial use, limited to 100 Documents in any rolling twelve-month period, as recorded in your Personal Key. The key is free and renews free on request. A sole practitioner or contractor processing a client’s files is making business use and needs a paid Plan, regardless of volume.
Free, for internal testing, assessment, proof of concept, and pilot activity only. It does not permit use in your business operations.
For use in your business, limited to the number of Seats you have paid for. Seats may be reassigned when an individual leaves or changes role, but may not be shared between individuals concurrently.
As set out in a separate order form or master agreement, which prevails over this Agreement to the extent of any conflict.
You will not, and will not permit any other person to:
5.1 Identified content is replaced, not merely covered. The Software writes a Protected Copy in which each identified value has been replaced by a placeholder token. The original value is not carried into that file. For text, CSV, JSON, XML, spreadsheet, and word-processor output the value is substituted before the file is written. For PDFs and images the page is rasterised and an opaque block is painted over the region, so neither the original pixels nor a text layer survive in the output.
5.2 Recovery requires the separate private report. The original values can be recovered only from the private report and key file the Software writes alongside the Protected Copy — never from the Protected Copy itself. Those files are secrets. If you share a Protected Copy, do not share the private report.
5.3 Verify before you share. No detection method identifies all sensitive content in all documents. The Software may fail to identify content that should be Blokked, and may Blok content that need not be. You must review every Protected Copy before sharing it. Your review, not the Software’s detection, is the final control over what is disclosed.
5.4 The Software does not modify your original Document.
5.5 Detection is probabilistic. It may produce false negatives and false positives. The Software provides a review step for this reason, and you agree to use it.
5.6 You are responsible for determining whether the Software is appropriate for your intended use, including any use where you are legally or professionally required to redact a document irreversibly.
The Software is a tool. It is not legal, medical, accounting, or compliance advice, and using it does not by itself make you compliant with any law, regulation, professional rule, or contractual obligation, including HIPAA, GDPR, CCPA/CPRA, PCI DSS, GLBA, bar or law society rules, and court practice directions.
You remain solely responsible for:
7.1 The Software processes Documents locally on the device or infrastructure where it is installed. We do not receive, transmit, store, or have access to Your Content.
7.2 You retain all rights in Your Content. We claim no licence over it.
7.3 The Software does not require an account. The redaction engine collects no telemetry or usage analytics, performs no crash reporting, makes no update checks, and validates licence keys entirely offline — it contains no outbound network client of any kind.
7.4 One exception, disclosed for completeness. The browser interface loads three third-party assets over the internet when you open it: web fonts from Google Fonts, and the PDF.js and jsPDF libraries from the jsDelivr CDN. Your Documents are never sent to them — they are code and font files the page fetches. Those providers will nevertheless see your IP address and the fact that the page was opened. PDF viewing and PDF export therefore require internet access. If you need fully air-gapped operation, use the command line interface, or tell us and we will supply a build that serves these assets locally.
7.5 Where we hold personal information you have given us directly — for example when requesting a demonstration or making a donation — our handling of it is described in our Privacy Policy. [PRIVACY POLICY URL]
8.1 Free Plan and Evaluation Keys. No fee is payable. Donations are voluntary, are not payment for the Software, confer no additional rights or allowance, and are non-refundable.
8.2 Paid Plans. Small Business Plan fees are USD $18 per Seat per month, billed monthly in advance, exclusive of sales, use, VAT, GST, and similar taxes, which you are responsible for except taxes on our net income. Enterprise fees are as stated in your order form.
8.3 Changes to fees. We may change fees on thirty (30) days' notice, effective at your next renewal.
8.4 Non-payment. If fees remain unpaid fourteen (14) days after notice, we may suspend the affected Seats.
8.5 Cancellation and refunds. You may cancel a paid Plan at any time; cancellation takes effect at the end of the current billing period. Fees already paid are non-refundable except where a refund is required by law. [CONFIRM REFUND POLICY]
8.6 Allowance, renewal and grace. Each Document processed consumes one unit of your Document Allowance and is recorded in a tamper-evident usage log held on your own machine. The Free Plan allowance resets every twelve months. Personal and Evaluation Keys renew free of charge on request, and we may ask for the usage log to verify key integrity. After a key expires the Software keeps working for the grace period recorded in the key, with warnings.
8.7 Nothing is deleted. If your allowance is exhausted or your key expires, the Software warns you and declines to process new Documents. It never deletes, alters, locks, encrypts, or withholds any Document, Protected Copy, report, or key file already on your systems. Everything you have already produced stays yours, permanently.
9.1 This Agreement begins when you first install or use the Software and continues until terminated.
9.2 You may terminate at any time by ceasing use and uninstalling the Software. Paid plans may be cancelled at any time; cancellation takes effect at the end of the current billing period.
9.3 We may terminate or suspend your licence immediately if you materially breach this Agreement.
9.4 On termination you must stop using and uninstall the Software. Because the Software runs on your own infrastructure, Protected Copies and original Documents already on your systems are unaffected by termination. Sections 4, 5, 6, 10, 11, 12, and 15 survive.
The Software is licensed, not sold. We and our licensors retain all right, title, and interest in the Software, including all intellectual property rights. Nothing in this Agreement transfers ownership to you.
Feedback you give us about the Software may be used by us without restriction and without obligation to you.
The Software includes third-party components licensed under their own terms, listed in the THIRD-PARTY-NOTICES.md file distributed with the Software. Where a third-party licence conflicts with this Agreement in respect of that component, the third-party licence prevails.
Except as expressly stated in this Agreement, and to the maximum extent permitted by applicable law, the Software is provided "as is" and "as available", without warranty of any kind, whether express, implied, statutory, or otherwise, including any implied warranty of merchantability, fitness for a particular purpose, non-infringement, accuracy, or that the Software will be uninterrupted or error-free.
We do not warrant that the Software will identify all sensitive content in any Document.
To the maximum extent permitted by law:
13.1 Neither party is liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, revenue, data, or goodwill, however caused.
13.2 Our total aggregate liability arising out of or relating to this Agreement is limited to the greater of the fees you paid us in the twelve (12) months before the event giving rise to the claim and USD $100.
13.3 Nothing in this Agreement excludes liability for fraud, fraudulent misrepresentation, death or personal injury caused by negligence, or any liability that cannot lawfully be excluded.
You will indemnify us against any claim brought by a third party arising from your use of the Software in breach of this Agreement, or from any Document or Protected Copy you disclose.
This Agreement is governed by the laws of the State of Wyoming, U.S.A., excluding its conflict-of-laws rules and excluding the UN Convention on Contracts for the International Sale of Goods. The state and federal courts located in Laramie County, Wyoming have exclusive jurisdiction, and you consent to their jurisdiction and waive any objection based on inconvenient forum. Each party waives any right to a trial by jury and to participate in a class, collective, or representative action.
Before filing proceedings, the complaining party will give written notice of the dispute and the parties will attempt in good faith to resolve it within thirty (30) days.
If you are a consumer, this section does not deprive you of the protection of mandatory consumer-protection law where you live, or of the right to bring proceedings in your local courts where that right cannot be waived.
You will comply with all applicable export-control and sanctions laws, including the U.S. Export Administration Regulations and the regulations administered by the U.S. Office of Foreign Assets Control. You confirm you are not located in, organised under the laws of, or ordinarily resident in a comprehensively embargoed country or territory, and that you are not a Specially Designated National or otherwise a restricted or denied party. The Software is "commercial computer software" under FAR 12.212 and DFARS 227.7202.
17.1 Changes. We may amend this Agreement by publishing an updated version and notifying you in the Software or by email. Continued use after the effective date constitutes acceptance. Material changes take effect no earlier than thirty (30) days after notice.
17.2 Assignment. You may not assign this Agreement without our written consent. We may assign it in connection with a merger, acquisition, or sale of assets.
17.3 Entire agreement. This Agreement is the entire agreement between us regarding the Software and supersedes all prior discussions.
17.4 Severability. If any provision is unenforceable, the rest remains in effect.
17.5 No waiver. A failure to enforce any provision is not a waiver of it.
17.6 Language. The English text of this Agreement governs.
