Terms of Use

Last Updated: August 18, 2026

These Terms of Use (the "Terms") govern your access to and use of PlagiarismSearch.com, including the website, user accounts, plagiarism detection, AI-content detection, document comparison, private Storage, reports, API access, integrations, and other products or services made available by PlagiarismSearch from time to time (collectively, the "Service").

Please read these Terms carefully. By creating an account, purchasing or subscribing to the Service, submitting an order form, accessing paid features, or otherwise using the Service, you agree to be bound by these Terms and our Privacy Policy. If you do not agree to these Terms, you must not use the Service.

1. Ownership and Contracting Entities

PlagiarismSearch.com is operated by System Technology Online Spain SL., registered in Spain, and System Tech Online USA Inc., registered in the United States.

For standard self-service paid transactions, the applicable contracting entity and merchant of record are determined as follows:

• System Tech Online USA Inc., having its registered office at 5900 Balcones Dr, Ste 100, Austin, TX 78731, USA, acts as the primary contracting party and merchant of record for card payment transactions initiated by users located outside the European Union (EU) and European Economic Area (EEA).
• System Technology Online Spain SL., having its registered office at Calle Pintor Pérez Gil 2, b.46, 03540 Alicante, Spain, acts as the primary contracting party and merchant of record for transactions processed through PayPal, regardless of the user's location, and for card payment transactions initiated by users within the EU/EEA.

A separate Order Form, enterprise agreement, or other written agreement may identify a different applicable contracting arrangement. Where such an agreement applies, it will control to the extent of any conflict with these Terms regarding its specific subject matter.

References in these Terms to "PlagiarismSearch," "we," "us," or "our" mean the applicable PlagiarismSearch contracting entity.

2. Eligibility and Accounts

You must have the legal capacity to enter into these Terms.

If you are under the age of legal majority in your jurisdiction, you may use the Service only where your use is authorized and supervised as required by applicable law, for example by a parent, guardian, school, university, or other authorized organization.

If you use the Service on behalf of a company, educational institution, government body, or other organization, you represent that you have authority to bind that organization to these Terms.

You are responsible for:

• providing accurate account information;
• keeping your account credentials confidential;
• maintaining the security of your account;
• all activity performed through your account or API credentials; and
• promptly notifying us if you become aware of unauthorized access or suspected compromise.

You must not share account credentials in a manner that circumvents the user, account, subscription, or usage limits applicable to your plan.

3. The Service

PlagiarismSearch provides tools designed to analyze submitted content for textual similarity, potential plagiarism, AI-generated content, and other characteristics supported by the applicable Service features.

Depending on the feature used, the Service may compare submitted content against publicly available Internet sources, available reference datasets, licensed or third-party source collections, and private reference documents made available through Storage or an organization account.

Reports may identify matching or potentially matching sources, similarity information, passages, and other analytical results.

PlagiarismSearch may modify, improve, add, remove, or replace Service features from time to time. We will not intentionally make a material change that removes a core paid feature during an active subscription without providing notice where required by applicable law or the applicable agreement.

4. License to Use the Service

Subject to these Terms, payment of any applicable fees, and compliance with applicable usage limits, PlagiarismSearch grants you a limited, non-exclusive, non-transferable, non-sublicensable right to access and use the Service for your personal, educational, internal business, or organizational purposes.

This license does not transfer ownership of the Service, software, algorithms, interfaces, trademarks, report formats, documentation, or other PlagiarismSearch intellectual property to you.

Except where expressly permitted by law or by us in writing, you may not:

• copy, modify, distribute, sell, lease, sublicense, or create derivative products from the Service;
• reverse engineer, decompile, disassemble, or attempt to discover source code or non-public algorithms used by the Service;
• circumvent technical restrictions, account limits, rate limits, payment requirements, or usage quotas;
• use automated means to access the Service except through an authorized API or other feature expressly provided for that purpose;
• use the Service to develop, train, benchmark, or operate a competing product by systematically extracting non-public Service functionality or data without our written authorization;
• interfere with the security, availability, or operation of the Service; or
• remove or alter proprietary notices displayed by PlagiarismSearch.

5. Customer Content

"Customer Content" means documents, text, files, reference materials, URLs, and other content that you or your authorized users submit to the Service.

You or the applicable rights holder retain ownership of Customer Content.

You grant PlagiarismSearch the limited rights necessary to host, retrieve, copy, process, analyze, index where applicable, transmit where technically necessary, and otherwise handle Customer Content solely as reasonably required to:

• provide the Service requested by you;
• generate and maintain reports;
• provide private Storage and document-comparison functionality;
• provide technical and customer support;
• investigate technical or security issues;
• prevent fraud, abuse, or unauthorized use; and
• comply with applicable legal obligations.

Customer Content is not automatically made available as a plagiarism source to unrelated PlagiarismSearch customers.

PlagiarismSearch does not use Customer Content submitted to the Service to train PlagiarismSearch AI or machine-learning models.

Additional information about how Customer Content is processed, retained, and deleted is provided in our Privacy Policy.

Certain services, including Paper Analysis and other services expressly described as involving human review, may be performed in whole or in part by authorized specialists. By ordering such a service, you authorize the Customer Content submitted for that order to be made available to the personnel reasonably necessary to perform the requested review.

6. Your Responsibilities for Customer Content

You are responsible for the Customer Content you submit and for your use of the Service.

You represent that you have the rights, permissions, legal basis, or other authority reasonably necessary to submit and process Customer Content through the Service.

This requirement does not mean that you must own every text that you submit for a legitimate plagiarism or similarity analysis. For example, educational or professional users may need to analyze material submitted to them or material for which they otherwise have lawful authority to perform the requested analysis.

You must not knowingly use the Service to:

• process content in violation of applicable law;
• infringe the rights of others beyond what is reasonably necessary for a lawful plagiarism, academic-integrity, research, compliance, or similar analysis;
• upload malicious code or content designed to compromise the Service;
• gain unauthorized access to another person's account, documents, or information;
• harass, threaten, exploit, or unlawfully monitor another person; or
• use the Service for fraudulent or unlawful purposes.

7. Private Storage and Organization Accounts

Documents uploaded to private Storage may be indexed so they can be used as reference documents for comparisons within the applicable customer account.

Storage documents are not automatically made searchable by unrelated PlagiarismSearch customers.

For organization accounts, authorized members may be permitted to share Storage documents for comparison with other authorized members of the same organization where the relevant sharing permission has been enabled.

The organization is responsible for configuring its users, permissions, and document-sharing settings appropriately.

Where an organization manages your account, the organization may have administrative access to account information, reports, submissions, and Storage content according to its permissions and applicable agreement.

8. API Use

If your plan includes API access, you may use the API only in accordance with these Terms, the applicable plan limits, and the technical documentation provided by PlagiarismSearch.

You are responsible for protecting API credentials and for requests made using your credentials.

You must not:

• exceed applicable API rate or usage limits;
• attempt to bypass usage accounting or billing controls;
• use API access to disrupt or place unreasonable load on the Service; or
• provide unauthorized third parties with access to your API credentials.

API processing may be asynchronous. Where supported, customers may use available status requests and callback functionality to receive or retrieve processing results.

9. Analytical Results and Appropriate Use

PlagiarismSearch reports are analytical tools intended to assist users in evaluating submitted content.

Similarity results, source matches, AI-detection results, and other automated outputs should be interpreted together with the underlying evidence and appropriate human review.

A similarity score is not, by itself, a determination that plagiarism has occurred. Likewise, an AI-detection result is not, by itself, a definitive determination regarding the authorship of a document.

Source availability can depend on factors outside PlagiarismSearch's control, including third-party indexing, availability, access restrictions, website configuration, and changes to external sources.

Reports should not be used as the sole basis for disciplinary, employment, legal, academic, or other high-impact decisions without appropriate independent review.

10. Fees, Plans, and Usage

Current pricing, plan limits, subscription periods, and included usage are displayed on the Website or in the applicable Order Form.

You agree to pay all fees associated with the plan or Service you purchase.

Depending on the applicable product, usage may be measured by words, submissions, documents, API requests, or other units specified for the relevant plan.

Where applicable, PlagiarismSearch may use a fair-usage or fair-words mechanism that adjusts word-balance consumption for qualifying duplicated text previously processed through the Service.

Prices and applicable taxes are shown or calculated as required during the purchase process. You are responsible for applicable taxes except to the extent PlagiarismSearch is required to collect or remit them.

Payments may be processed by third-party payment service providers. Available payment methods are displayed at checkout and may change over time.

11. Subscriptions, Renewal, and Cancellation

Where you purchase a recurring subscription, the subscription will renew automatically at the billing interval shown when you subscribe, unless you cancel it before the next renewal date.

You may cancel a recurring subscription through the cancellation functionality available in your account or by contacting PlagiarismSearch through the support channels made available on the Website.

Cancellation stops future renewals. Unless applicable law requires otherwise, cancellation does not retroactively cancel a billing period that has already begun and does not automatically generate a refund for amounts already charged.

You will normally retain access to the paid features included in your subscription until the end of the billing period for which payment has already been made, unless access is suspended or terminated under these Terms.

Non-recurring products or usage packages do not automatically renew unless expressly stated at the time of purchase.

12. Trials and Evaluation Access

PlagiarismSearch may provide free trials, promotional balances, evaluation limits, or other no-charge access at its discretion.

Trial duration, usage limits, eligibility, and available features may be different from paid plans and may be changed or withdrawn where permitted by law.

Unless we expressly agree otherwise, a customer or organization may be limited to one trial or evaluation allocation.

Additional evaluation capacity may be provided to business or institutional customers as part of a technical evaluation or controlled pilot.

13. Refunds and Consumer Withdrawal Rights

Voluntary Refund Policy

Except where applicable law requires otherwise, fees paid for the Service are non-refundable after paid usage has occurred.

PlagiarismSearch may consider a refund request for the most recent billing period under its voluntary refund policy where:

• the request is submitted within 5 calendar days of the applicable charge; and
• no paid Service usage has occurred during that billing period.

For purposes of the voluntary refund policy, paid usage may include a paid document submission, paid API request, or other use of a paid feature or balance.

Refund eligibility under this voluntary policy does not apply to previous billing periods.

Refund requests may be submitted to support@plagiarismsearch.com.

Failed Processing

If a plagiarism-checking job reaches an Error/Failed state without producing the applicable report, the usage balance charged for that failed check is returned in accordance with the Service's billing logic. A return of usage balance is different from a monetary refund of a subscription or purchase.

Mandatory Consumer Rights

Nothing in these Terms limits any mandatory refund, cancellation, withdrawal, conformity, or other consumer rights that cannot lawfully be excluded.

Consumers in the EU/EEA may have a statutory right to withdraw from an eligible distance service contract within 14 days from conclusion of the contract, subject to the conditions and exceptions established by applicable law.

Any charge for Service supplied during an applicable withdrawal period, reduction of a refund, or loss of a statutory right of withdrawal will apply only where the conditions required by applicable law have been satisfied.

You may exercise any applicable statutory withdrawal right through the withdrawal functionality made available by PlagiarismSearch where required by law, or by sending us a clear statement of your decision to withdraw at support@plagiarismsearch.com.

14. Support and Service Availability

PlagiarismSearch provides customer and technical support through the support channels made available on the Website.

The time required to investigate or resolve an issue depends on its nature and complexity.

Unless a separate Order Form, enterprise agreement, or Service Level Agreement expressly provides otherwise, the standard Service does not include guaranteed:

• support response or resolution times;
• Service uptime percentages;
• report-completion times; or
• source-coverage levels.

Processing times may vary depending on document size, the number and availability of candidate sources, external source retrieval, system load, and other technical factors.

15. Third-Party Services and Integrations

The Service may interact with or depend on third-party websites, payment providers, cloud services, APIs, data sources, or integrations.

Examples may include payment-processing services, cloud-storage integrations, analytics providers, infrastructure providers, and external sources used in connection with document analysis.

Your use of a third-party service may also be subject to that third party's own terms and privacy policies.

PlagiarismSearch is not responsible for the independent operation, content, availability, or practices of third-party services that are outside our reasonable control.

16. Privacy and Data Processing

Our handling of personal data and Customer Content is described in our Privacy Policy and Privacy and Data Security information.

Our use of cookies and similar technologies is described in our Cookie Policy.

Where PlagiarismSearch processes personal data on behalf of a business, educational institution, or other organization and applicable law requires a controller-processor agreement, that processing will be governed by appropriate binding data-processing terms, including a Data Processing Addendum (DPA) where applicable. Such terms may be incorporated into an Order Form or another written agreement.

If a DPA, Order Form, or other separate written agreement has been entered into, its provisions will control over these Terms to the extent of any conflict relating specifically to the subject matter governed by that agreement.

17. Confidentiality

For business and institutional customers, each party may receive non-public information that is identified as confidential or that reasonably should be understood to be confidential given its nature and the circumstances of disclosure.

Each party will use reasonable measures to protect such confidential information and will use it only for the purposes of the parties' relationship, except where disclosure is authorized by the other party or required by law.

Confidential information does not include information that:

• is or becomes publicly available without breach of an obligation;
• was lawfully known to the receiving party without confidentiality restrictions;
• is lawfully received from a third party without a confidentiality obligation; or
• is independently developed without use of the other party's confidential information.

18. Intellectual Property

PlagiarismSearch and its licensors retain all rights, title, and interest in the Service and its underlying technology, software, algorithms, interfaces, designs, trademarks, logos, documentation, report formats, and other intellectual property.

Your ownership of Customer Content is not transferred to PlagiarismSearch.

Subject to these Terms, you may use and download reports generated for your account for your legitimate personal, educational, internal business, institutional, or professional purposes.

No rights are granted except those expressly stated in these Terms.

19. Feedback

If you voluntarily provide suggestions, ideas, feature requests, or other feedback about the Service, you grant PlagiarismSearch a worldwide, perpetual, irrevocable, royalty-free right to use that feedback to develop, improve, and operate its products and services, provided that doing so does not grant PlagiarismSearch ownership of your Customer Content.

PlagiarismSearch will not publicly identify you or your organization as the source of feedback without permission where identification would disclose a non-public customer relationship.

20. Customer Names, Logos, and Publicity

PlagiarismSearch will not use an organization's name, logo, trademarks, or the fact that the organization is a PlagiarismSearch customer in public marketing or promotional materials without the organization's prior written consent.

This restriction does not prevent PlagiarismSearch from identifying a customer where disclosure is required by law or expressly authorized in a separate agreement.

21. Suspension and Termination

We may suspend or terminate access to all or part of the Service where reasonably necessary to:

• address a material breach of these Terms or an applicable agreement;
• protect the security, integrity, or availability of the Service;
• prevent fraud, abuse, unauthorized access, or unlawful activity;
• respond to non-payment;
• comply with applicable law, a court order, or a lawful governmental request; or
• prevent material harm to PlagiarismSearch, our users, or third parties.

Where reasonably practicable and legally permitted, we will provide notice before a material suspension or termination and an opportunity to address the relevant issue.

You may stop using the Service at any time. Cancellation of a recurring subscription is governed by Section 11.

Following termination, Customer Content and account data will be retained or deleted in accordance with our Privacy Policy, applicable law, and any separate agreement that applies to your account.

22. Disclaimer of Warranties

Nothing in this section excludes warranties or rights that cannot lawfully be excluded.

To the maximum extent permitted by applicable law, the Service and reports are provided on an "as is" and "as available" basis.

PlagiarismSearch does not warrant that:

• the Service will always be uninterrupted or error-free;
• every publicly available or private source will be discoverable or accessible;
• every similarity, plagiarism, or AI-related instance will be detected;
• every report or automated result will be complete or error-free; or
• the Service will meet every specific purpose or requirement that has not been expressly agreed in writing.

PlagiarismSearch will nevertheless provide the Service with the level of care required by applicable law and any separate contractual commitments expressly agreed with the customer.

23. Limitation of Liability

Nothing in these Terms excludes or limits liability where such exclusion or limitation is prohibited by applicable law, including any mandatory consumer rights.

To the maximum extent permitted by law, PlagiarismSearch and its affiliates, officers, employees, licensors, and suppliers will not be liable for indirect, incidental, special, punitive, exemplary, or consequential damages, or for loss of profits, revenue, business opportunities, goodwill, or data, arising out of or relating to the Service, where such damages may lawfully be excluded.

To the maximum extent permitted by law, the aggregate liability of PlagiarismSearch arising out of or relating to the standard Service and these Terms will not exceed the fees paid by you to PlagiarismSearch for the Service during the 30-day period immediately preceding the event that first gave rise to the claim.

This limitation does not apply where a separate Order Form or enterprise agreement expressly provides a different liability arrangement.

You remain responsible for interpreting reports and deciding how to use their results, including whether additional human, academic, professional, or legal review is appropriate.

24. Indemnification by Business and Organizational Users

If you use the Service on behalf of a business, educational institution, government body, or other organization, then, to the extent permitted by applicable law, that organization agrees to indemnify and hold harmless PlagiarismSearch and its affiliates, officers, employees, and licensors from third-party claims, damages, liabilities, and reasonable costs arising from:

• the organization's unlawful use of the Service;
• Customer Content submitted without the rights or authority required for the relevant use;
• the organization's material breach of these Terms; or
• the organization's violation of applicable law or third-party rights.

This section does not require indemnification to the extent a claim results from PlagiarismSearch's own breach, unlawful conduct, or other responsibility that cannot lawfully be transferred to the customer.

25. Force Majeure

Neither party will be liable for delay or failure to perform an obligation, other than payment obligations, to the extent caused by circumstances beyond its reasonable control.

Such circumstances may include natural disasters, war, terrorism, civil unrest, labor disputes, widespread telecommunications or infrastructure failures, governmental actions, significant third-party network outages, or similar events outside the affected party's reasonable control.

26. Changes to the Service and These Terms

We may update these Terms from time to time to reflect changes in the Service, applicable law, security requirements, or our business practices.

When we make material changes, we will update the "Last Updated" date and provide additional notice where required by applicable law.

Changes will apply prospectively from their effective date. Where applicable law requires affirmative acceptance of a material change, we will request it before the change becomes binding.

27. Governing Law and Disputes

Unless a separate written agreement states otherwise, these Terms and any dispute arising out of or relating to them are governed by the laws of Spain, without regard to conflict-of-law principles.

Nothing in this choice of law deprives a consumer of mandatory protections available under the laws that apply to the consumer and that cannot lawfully be waived by contract.

Nothing in these Terms restricts a consumer's right to bring a claim before a court or other competent body where applicable consumer law provides such a right.

Before commencing formal proceedings, we encourage users to contact us so that we can attempt to resolve the issue directly.

28. General Provisions

If any provision of these Terms is found to be invalid or unenforceable, that provision will be enforced to the maximum extent permitted by law, and the remaining provisions will remain in effect.

A failure by either party to enforce a provision of these Terms does not waive the right to enforce it later.

You may not assign your rights or obligations under these Terms without our prior written consent, except where applicable law provides otherwise. PlagiarismSearch may assign these Terms in connection with a merger, acquisition, corporate reorganization, or transfer of substantially all relevant business assets, subject to applicable law.

Unless expressly stated otherwise, these Terms do not create rights for third-party beneficiaries.

These Terms, together with the documents and agreements expressly incorporated into them, constitute the agreement governing your use of the Service. A separate Order Form, DPA, enterprise agreement, or other written agreement may supplement or modify these Terms for the customer to whom it applies.

If these Terms are translated into another language and there is a conflict between versions, the English version will control to the extent permitted by applicable law.
