Terms of Service
Last updated: 30 September 2026
1. Introduction and Acceptance
These Terms and Conditions ("Terms") constitute a legally binding agreement between you ("Customer", "you", "your") and DarkStrata Ltd ("DarkStrata", "we", "us", "our"), a company registered in England and Wales (Company No: 16521338).
By accessing or using the DarkStrata platform, website, APIs, or any related services (collectively, the "Services"), you acknowledge that you have read, understood, and agree to be bound by these Terms. If you are entering into these Terms on behalf of an organisation, you represent and warrant that you have the authority to bind that organisation to these Terms.
If you do not agree to these Terms, you must not access or use our Services.
2. Definitions
In these Terms, unless the context otherwise requires:
- "Account" means the account created by you to access and use the Services.
- "Authorised Users" means the individuals authorised by you to access and use the Services under your Account.
- "Confidential Information" means any information disclosed by one party to the other that is marked as confidential or would reasonably be understood to be confidential.
- "Customer Data" means all data, content, and information submitted, uploaded, or otherwise provided by you or your Authorised Users to the Services.
- "Documentation" means the user guides, technical documentation, and other materials provided by DarkStrata relating to the Services.
- "Intellectual Property Rights" means patents, trademarks, service marks, copyright, database rights, design rights, know-how, trade secrets, and all other intellectual property rights, whether registered or unregistered.
- "Subscription" means your paid access to the Services for the applicable Subscription Term.
- "Subscription Term" means the period during which you have paid access to the Services, as specified in your order or subscription agreement.
3. Services
3.1 Provision of Services
Subject to your compliance with these Terms and payment of applicable fees, DarkStrata grants you a non-exclusive, non-transferable, revocable right to access and use the Services during the Subscription Term solely for your internal business purposes.
3.2 Service Availability
We will use commercially reasonable efforts to make the Services available 24 hours a day, 7 days a week, except for planned maintenance (of which we will provide reasonable notice) and circumstances beyond our reasonable control. We do not guarantee uninterrupted or error-free operation of the Services.
3.3 Modifications to Services
We reserve the right to modify, update, or discontinue any aspect of the Services at any time. We will provide reasonable notice of any material changes that adversely affect your use of the Services. Continued use of the Services following such notice constitutes acceptance of the modifications.
3.4 Beta Features
We may offer beta or preview features that are not generally available. Such features are provided "as is" without warranty and may be modified or discontinued at any time without notice.
3.5 Free Tier Credential Check Licence
Where you access the Credential Check API without a paid subscription (the "Free Tier"), DarkStrata grants you a non-exclusive, non-transferable, revocable licence to use the Credential Check API solely for your own internal business purposes, namely verifying credentials submitted to websites, applications, and systems that you own or operate. The Free Tier is subject to a usage allowance of 500 credential checks per calendar month, which DarkStrata may vary on reasonable notice.
The Free Tier licence does not permit you to: (a) incorporate, embed, bundle, or otherwise make the Credential Check API available as part of any product, plugin, application, or service that you sell, license, resell, or otherwise supply to a third party; (b) operate the Credential Check API on behalf of, or for the benefit of, any third party, including as a managed service or agency arrangement; or (c) provide access to the Credential Check API, or its results, to any third party.
Any such use requires a separate written partner licence from DarkStrata. Use of the Free Tier for the purposes described above is a material breach of these Terms and DarkStrata may suspend or revoke the relevant API credentials immediately under clause 14. Where you create Free Tier API credentials you will be asked to confirm acceptance of this restriction, and that confirmation is recorded against the credential.
The Free Tier allowance applies per organisation, across all API credentials that organisation holds. You must not, and must not permit any person to, circumvent or attempt to circumvent the allowance, including by creating or operating multiple Accounts or organisations, by distributing usage across Accounts under common control, or by any other means. DarkStrata may aggregate usage across Accounts it reasonably believes to be under common control and apply a single allowance to them.
The Free Tier is provided "as is" and "as available". Clause 3.2 does not apply to it: DarkStrata gives no availability, uptime, latency, accuracy, or support commitment in respect of the Free Tier, and may rate limit, suspend, reduce the allowance for, or withdraw it at any time. You must not rely on the Free Tier where failure or unavailability of a credential check would cause loss, and you remain responsible for your own authentication and access controls irrespective of any result returned.
DarkStrata may monitor Free Tier usage to verify compliance with this clause 3.5 and may, on reasonable written notice, request information about how you use the Credential Check API and the websites, applications, and systems on which it is deployed. You agree to respond to such a request promptly and accurately. Failure to do so is grounds for suspension under clause 14.
This clause 3.5 does not apply to Credential Check access provided under a paid subscription or a partner licence, which is governed by the applicable order form or licence agreement. A trial does not constitute a paid subscription for the purposes of this clause, and credentials created during a trial remain subject to it when the trial ends.
4. Account Registration and Security
4.1 Account Creation
To use the Services, you must create an Account by providing accurate, current, and complete information. You agree to update your information to maintain its accuracy throughout the Subscription Term.
4.2 Account Security
You are responsible for maintaining the confidentiality of your Account credentials and for all activities that occur under your Account. You must immediately notify us of any unauthorised access to or use of your Account.
4.3 Authorised Users
You may permit Authorised Users to access the Services under your Account, subject to your Subscription limits. You are responsible for ensuring that all Authorised Users comply with these Terms and are liable for any breach by your Authorised Users.
4.4 Eligibility
The Services are intended for business and professional use. By creating an Account or using the Services, you represent and warrant that you are at least 18 years old, that you are not a person or entity barred from receiving the Services under applicable sanctions or export-control laws, and that you will use the Services in a business or professional capacity and not to conduct personal surveillance of, or otherwise target, other individuals.
5. Customer Obligations
5.1 Acceptable Use
You agree to use the Services only for lawful purposes and in accordance with these Terms. You shall not:
- Use the Services in any way that violates applicable laws or regulations
- Use the Services to infringe upon or violate the rights of any third party
- Use the Services to monitor, query, scan, profile, track, or analyse any domain, network, IP address, email address, account, individual, or other asset that you do not own or control, or that you are not expressly authorised in writing to monitor
- Use the Services to stalk, harass, threaten, intimidate, surveil, or exercise coercive control over any individual, including in connection with intimate-partner or domestic monitoring
- Use the Services to collect, aggregate, or expose personal data about any individual for the purposes of harassment, doxxing, or unlawful surveillance
- Provide false, stolen, or misleading identity, registration, verification, or payment information, or impersonate or misrepresent your affiliation with any person or organisation
- Attempt to gain unauthorised access to any systems, networks, or data
- Use the Services to transmit malware, viruses, or other harmful code
- Interfere with or disrupt the integrity or performance of the Services
- Reverse engineer, decompile, or disassemble any aspect of the Services
- Use the Services to conduct vulnerability scanning or penetration testing against third parties without their explicit consent
- Resell, sublicense, or otherwise make the Services available to third parties without our prior written consent
- Remove or alter any proprietary notices or labels on the Services
5.2 Customer Data
You retain all rights in and to your Customer Data. By submitting Customer Data to the Services, you grant DarkStrata a non-exclusive, worldwide, royalty-free licence to use, copy, store, and process Customer Data solely for the purpose of providing and improving the Services.
You represent and warrant that you have all necessary rights and consents to submit Customer Data to the Services and that such submission does not violate any applicable laws or third-party rights.
5.3 Asset Ownership and Verification
Many features of the Services allow you to add, monitor, query, scan, or analyse domains, subdomains, IP addresses, email addresses, and other identifiers or assets (each an "Asset"). You represent and warrant that, for every Asset you add, submit, query, monitor, or analyse through the Services, you own or control that Asset, or are expressly authorised in writing by its owner or registrant to do so. This warranty applies regardless of whether the Asset is persistently added to your Account and regardless of whether we require verification for the feature in question.
Before granting access to features we designate as sensitive, we may require you to complete ownership verification, which may include DNS record checks, file-based verification, or verification via email addresses at the domain. Where we require verification, you must complete it before using the relevant feature, and we may withhold, restrict, or revoke access to any feature or Asset until verification is satisfactorily completed.
Adding, querying, or analysing an Asset for which you cannot or will not provide valid proof of ownership or authorisation, or providing falsified or misleading verification information, constitutes a material breach of these Terms. In such cases we may, without limiting our other rights, immediately suspend or permanently close your Account under Section 13.3 and withhold any refund of fees paid.
5.4 Security Research and Vulnerability Disclosure
DarkStrata does not operate a bug bounty programme and does not offer monetary rewards, swag, hall-of-fame recognition, or any other compensation in exchange for vulnerability reports or security research findings relating to the Services. Any security testing you perform against the Services remains subject to Section 5.1 (Acceptable Use); unauthorised scanning, testing, or exploitation of the Services, or of other customers' Accounts, is prohibited and may result in suspension or termination of your Account.
Responsible disclosure of suspected vulnerabilities is welcomed and should be submitted in accordance with our security.txt. Submitting a vulnerability report does not entitle you to any payment, recognition, or other reward, and does not create any contractual relationship beyond these Terms.
5.5 Lawful Basis for Third-Party Data
Where your use of the Services involves the monitoring, collection, or analysis of personal data relating to any individual other than yourself, you represent and warrant that you have a valid lawful basis for such processing under the UK GDPR and all other applicable data protection laws, and that you act as the data controller in respect of that processing. You are solely responsible for ensuring that your use of the Services complies with applicable data protection, privacy, surveillance, and anti-harassment laws, and you will indemnify DarkStrata in accordance with Section 12 for any breach of this Section.
5.6 Identity and Anti-Fraud
You must not create an Account or use the Services using a false, stolen, or misappropriated identity, nor impersonate or misrepresent your affiliation with any person or organisation. You must not submit false, stolen, or unauthorised payment details, and any chargeback, payment reversal, or fraudulent payment activity constitutes a material breach of these Terms. We may decline, suspend, or permanently close any Account that we reasonably believe has been created or used fraudulently, by a sanctioned person or entity, or otherwise in breach of this Section, without refund and without limiting our other rights.
5.7 Monitoring, Reporting, and Cooperation
We may log, monitor, and audit the Assets you query and the activity conducted through your Account in order to detect, prevent, and investigate breaches of these Terms, fraud, and unlawful use. You acknowledge that you have no expectation of anonymity in respect of such activity where we are investigating suspected abuse. Where we reasonably believe the Services are being used to stalk, harass, defraud, or otherwise harm any person, or to commit a criminal offence, we may report the relevant activity and associated Account information to law enforcement, regulators, or affected parties, and may preserve related records for that purpose.
6. Fees and Payment
6.1 Subscription Fees
You agree to pay all fees applicable to your Subscription as set out in your order or as displayed on our website. All fees are quoted in the currency specified and are exclusive of VAT and other applicable taxes unless otherwise stated.
6.2 Payment Terms
Unless otherwise agreed, fees are payable in advance for each Subscription Term. We may charge fees via credit card, direct debit, or invoice, as applicable to your Subscription. Partner (MSP) accounts are invoiced monthly in arrears for their client organisations, payable within 30 days of the invoice date. Late payments may be subject to interest at the rate of 4% above the Bank of England base rate.
6.3 Price Changes
We may change our fees by giving you at least 30 days' notice by email. For Subscriptions with a fixed Subscription Term, the new fees apply from your next renewal. For partner (MSP) accounts billed monthly in arrears, new fees and any change to your partner discount apply from the first calendar month that starts after the notice period ends. If you do not accept a change you may cancel your Subscription, or remove the affected client organisations, before it takes effect. You will not pay the new fees for any period before that date.
6.4 Refunds
Except as required by law or as expressly set out in these Terms, all fees are non-refundable. If we terminate your Account due to your breach of these Terms, no refund will be provided.
7. Intellectual Property
7.1 DarkStrata IP
The Services, including all software, algorithms, user interfaces, designs, documentation, and other materials, are owned by or licensed to DarkStrata and are protected by Intellectual Property Rights. Except for the limited rights expressly granted in these Terms, DarkStrata reserves all rights in and to the Services.
7.2 Feedback
If you provide us with suggestions, ideas, or feedback regarding the Services ("Feedback"), you grant us a perpetual, irrevocable, worldwide, royalty-free licence to use, modify, and incorporate such Feedback into the Services without any obligation to you.
7.3 Trademarks
"DarkStrata" and our logos are trademarks of DarkStrata Ltd. You may not use our trademarks without our prior written consent.
8. Confidentiality
Each party agrees to protect the other party's Confidential Information using the same degree of care it uses to protect its own confidential information, but no less than reasonable care. Neither party shall disclose the other's Confidential Information to any third party except as necessary to perform its obligations under these Terms or as required by law.
Confidential Information does not include information that: (a) is or becomes publicly available through no fault of the receiving party; (b) was rightfully known to the receiving party prior to disclosure; (c) is rightfully obtained from a third party without restriction; or (d) is independently developed without use of the disclosing party's Confidential Information.
9. Data Protection
We process personal data in accordance with our Privacy Policy and applicable data protection laws, including the UK GDPR and the Data Protection Act 2018.
Where we process personal data on your behalf as a data processor, our Data Processing Agreement applies and forms part of these Terms.
