Section 01
1. Ownership and Contracting Entities
PlagiatCheck.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 purchases, the company that acts as the contracting party and merchant of record depends on the user’s location and payment method:
- System Tech Online USA Inc., with its registered office at 5900 Balcones Dr, Ste 100, Austin, TX 78731, USA, serves as the primary contracting entity and merchant of record for card payments initiated by users located outside the European Union (EU) and European Economic Area (EEA).
- System Technology Online Spain SL., with its registered office at Calle Pintor Pérez Gil 2, b.46, 03540 Alicante, Spain, serves as the primary contracting entity and merchant of record for payments made through PayPal regardless of user location and for card payments initiated by users in the EU/EEA.
An enterprise agreement, or another written contract may specify a different contracting arrangement. If such an agreement applies, its provisions will take precedence over these Terms where the two documents conflict on the specific subject covered by that agreement.
In these Terms, “PlagiatCheck,” “we,” “us,” and “our” refer to the PlagiatCheck contracting entity applicable to the relevant transaction or Service.
Section 02
2. Eligibility and Accounts
You may use the Service only if you have the legal capacity required to enter into a binding agreement under the laws applicable to you.
If you are below the age of legal majority in your jurisdiction, you may use the Service only when such use is properly authorized and supervised as required by applicable law, including where authorization is provided by a parent, guardian, school, university, or other authorized organization.
If you access or use the Service for a company, educational institution, government organization, or another legal entity, you confirm that you have the authority to accept these Terms on that organization’s behalf.
You are responsible for:
- supplying complete and accurate account information;
- protecting the confidentiality of your login credentials;
- taking reasonable steps to secure your account;
- all activities carried out through your account or API credentials; and
- informing us without undue delay if you discover unauthorized access or believe your account may have been compromised.
You must not share account credentials in a way that bypasses or defeats the user, account, subscription, or usage restrictions associated with your plan.
Section 03
3. The Service
PlagiatCheck offers technology intended to analyze submitted materials for textual similarities, potential plagiarism, AI-generated content, and other characteristics supported by the particular Service feature being used.
Depending on the functionality selected, submitted materials may be compared with publicly accessible Internet content, available reference datasets, licensed or third-party source collections, and private reference materials made available through Storage or an organization account.
Reports may contain identified or potentially relevant sources, similarity information, matching passages, and other analytical findings produced by the applicable feature.
We may periodically enhance, change, introduce, discontinue, or replace individual Service features. Where required by applicable law or an applicable agreement, we will provide notice before intentionally removing a core paid feature during an active subscription.
Section 04
4. License to Use the Service
Provided that you comply with these Terms, pay all applicable charges, and remain within the usage limits of your plan, PlagiatCheck grants you a limited, non-exclusive, non-transferable, non-sublicensable right to access and use the Service for personal, educational, internal business, or organizational purposes.
This permission does not give you ownership of the Service or any underlying software, algorithms, interfaces, trademarks, report designs, documentation, or other intellectual property belonging to PlagiatCheck.
Unless applicable law expressly permits it or we have given you written authorization, you may not:
- copy, alter, distribute, sell, lease, sublicense, or create derivative products based on the Service;
- reverse engineer, decompile, disassemble, or otherwise attempt to obtain source code or confidential algorithms used by the Service;
- circumvent technical safeguards, account restrictions, rate limits, payment requirements, or usage quotas;
- access the Service through automated methods except by means of an authorized API or another feature specifically designed for automated access;
- systematically extract non-public Service functionality or data in order to develop, train, benchmark, or operate a competing product without our written permission;
- interfere with the security, availability, performance, or proper operation of the Service; or
- remove, conceal, or modify proprietary notices displayed by PlagiatCheck.
Section 05
5. Customer Content
“Customer Content” refers to documents, text, files, reference materials, URLs, and other information that you or your authorized users submit to the Service.
You, or the applicable owner of the relevant rights, continue to own Customer Content.
You give PlagiatCheck the limited permissions needed to host, retrieve, reproduce, process, analyze, index where applicable, transmit when technically required, and otherwise handle Customer Content only to the extent reasonably necessary to:
- deliver the Service you have requested;
- create and maintain reports;
- operate private Storage and document-comparison features;
- provide customer and technical assistance;
- identify and investigate technical or security problems;
- detect and prevent fraud, abuse, or unauthorized activity; and
- meet applicable legal requirements.
Customer Content is not automatically turned into a plagiarism source accessible to unrelated PlagiatCheck customers.
PlagiatCheck does not use Customer Content submitted through the Service to train its AI or machine-learning models.
Further details concerning the processing, retention, and deletion of Customer Content are provided in our Privacy Policy.
Some services, including Paper Analysis and other services expressly identified as involving human review, may be performed entirely or partly by authorized specialists. When you order such a service, you authorize the Customer Content associated with that order to be made available to personnel who reasonably require access in order to complete the requested review.
Section 06
6. Your Responsibilities for Customer Content
You remain responsible for all Customer Content you submit and for the way you use the Service.
You confirm that you have the necessary rights, permissions, legal basis, or other lawful authority to submit and process Customer Content through the Service.
This does not require you to own every piece of text submitted for a legitimate plagiarism or similarity check. For example, educators, institutions, and professional users may lawfully analyze material submitted to them or material they are otherwise authorized to review.
You must not knowingly use the Service to:
- process material in breach of applicable law;
- violate another person’s rights beyond what is reasonably necessary for a lawful plagiarism, academic-integrity, research, compliance, or comparable analysis;
- submit malicious software, code, or content intended to compromise the Service;
- obtain unauthorized access to another user’s account, documents, or information;
- harass, threaten, exploit, or unlawfully monitor another individual; or
- engage in fraudulent or otherwise unlawful activity.
Section 07
7. Private Storage and Organization Accounts
Files placed in private Storage may be indexed so that they can serve as reference materials for comparisons within the relevant customer account.
Storage documents are not automatically made searchable or available to unrelated PlagiatCheck customers.
For organization accounts, authorized users may be able to share Storage documents with other authorized members of the same organization for comparison when the applicable sharing permission has been enabled.
The organization is responsible for setting up its users, permissions, and document-sharing options correctly.
If an organization administers your account, that organization may have administrative access to account information, submissions, reports, and Storage content according to its permissions and the applicable agreement.
Section 08
8. API Use
If API functionality is included in your plan, you may use the API only in accordance with these Terms, the limits of your plan, and the technical documentation supplied by PlagiatCheck.
You are responsible for keeping API credentials secure and for all requests submitted using those credentials.
You must not:
- exceed the API rate or usage restrictions applicable to your plan;
- attempt to manipulate or bypass usage measurement, accounting, or billing mechanisms;
- use the API in a way that disrupts the Service or creates an unreasonable load on its infrastructure; or
- give unauthorized third parties access to your API credentials.
API operations may be completed asynchronously. Where the functionality is supported, customers may use status requests and callback mechanisms to obtain or retrieve processing results.
Section 09
9. Analytical Results and Appropriate Use
PlagiatCheck reports are analytical resources intended to help users assess submitted materials.
Similarity findings, source matches, AI-detection outputs, and other automated results should be considered together with the underlying evidence and, where appropriate, human review.
A similarity percentage alone does not establish that plagiarism has taken place. Similarly, an AI-detection result alone does not conclusively establish who authored a document.
The availability of sources may depend on circumstances outside PlagiatCheck’s control, including third-party indexing, source availability, access restrictions, website settings, and changes made to external websites.
Reports should not be treated as the sole basis for disciplinary, employment, legal, academic, or other decisions with significant consequences without suitable independent review.
Section 10
10. Fees, Plans, and Usage
The Website or applicable Order Form displays the current prices, plan restrictions, subscription periods, and usage included with each Service.
You agree to pay all charges associated with the plan or Service you select.
Depending on the product, usage may be calculated according to words, submissions, documents, API requests, or another unit specified for the applicable plan.
Where applicable, PlagiatCheck may operate a fair-use or fair-words mechanism under which the consumption of a word balance can be adjusted for qualifying duplicated text that has previously been processed through the Service.
Prices and applicable taxes are displayed or calculated during checkout as required. You are responsible for taxes applicable to your purchase except where PlagiatCheck is legally required to collect or remit them.
Payments may be handled by independent payment processors. The payment options available to you are shown during checkout and may change over time.
Section 11
11. Subscriptions, Renewal, and Cancellation
If you purchase a recurring subscription, it will automatically renew at the billing interval presented at the time of purchase unless you cancel it before the next renewal date.
You may cancel a recurring subscription through the cancellation option provided in your account or by contacting PlagiatCheck using the support channels available on the Website.
Cancellation prevents future renewals. Unless applicable law provides otherwise, it does not cancel a billing period that has already started and does not by itself create an entitlement to a refund for charges that have already been made.
Normally, you may continue using the paid functionality included in your subscription until the end of the period already paid for, unless your access is suspended or terminated under these Terms.
Products or usage packages purchased on a non-recurring basis will not renew automatically unless the purchase terms expressly state otherwise.
Section 12
12. Trials and Evaluation Access
PlagiatCheck may, at its discretion, offer free trials, promotional balances, evaluation allowances, or other forms of no-cost access.
The duration, usage limits, eligibility requirements, and available functionality of trial or evaluation access may differ from paid plans and may be modified or withdrawn where legally permitted.
Unless we specifically agree otherwise, an individual customer or organization may be limited to one trial or evaluation allocation.
Business and institutional customers may receive additional evaluation capacity as part of a technical assessment or controlled pilot program.
Section 13
13. Refunds and Consumer Withdrawal Rights
Voluntary Refund Policy
Unless applicable law requires otherwise, payments made for the Service are not refundable once paid usage has taken place.
PlagiatCheck may review a refund request concerning the most recent billing period under its voluntary refund policy when:
- the request is made within 5 calendar days after the relevant charge; and
- no paid Service usage has taken place during that billing period.
For this voluntary refund policy, paid usage may include submitting a paid document, making a paid API request, or using another paid feature or balance.
This voluntary refund policy does not provide refunds for earlier billing periods.
Refund requests may be sent to [email protected].
Failed Processing
If a plagiarism-checking task reaches an Error or Failed status and does not produce the applicable report, the usage balance charged for that unsuccessful check will be returned in accordance with the Service’s billing logic. Returning a usage balance does not constitute a monetary refund of a subscription or purchase.
Mandatory Consumer Rights
Nothing in these Terms removes or restricts any mandatory refund, cancellation, withdrawal, conformity, or other consumer protection right that cannot legally be excluded.
Consumers located in the EU/EEA may, where applicable, have a statutory right to withdraw from an eligible distance-service contract within 14 days after the contract is concluded, subject to the requirements and exceptions established by applicable law.
Any charge for Service supplied during a withdrawal period, any reduction in a refund, or any loss of a statutory withdrawal right will apply only where the conditions required under applicable law have been met.
Where a statutory withdrawal right applies, you may exercise it using any withdrawal functionality provided by PlagiatCheck where required by law, or by sending a clear statement of your decision to withdraw to [email protected].
Section 14
14. Support and Service Availability
PlagiatCheck offers customer and technical assistance through the support channels made available on the Website.
The time needed to investigate or resolve a support request may vary according to the type and complexity of the issue.
Unless an Order Form, enterprise agreement, or Service Level Agreement expressly states otherwise, the standard Service does not guarantee:
- a particular support response or resolution time;
- a specified Service uptime percentage;
- a fixed report-completion time; or
- a particular level of source coverage.
Processing times may differ based on document length, the quantity and availability of potential sources, retrieval of external material, system demand, and other technical circumstances.
