Privacy Policy

Last Updated: August 18, 2026

This Privacy Policy explains how PlagiarismSearch collects, uses, stores, shares, and protects personal data when you visit PlagiarismSearch.com, create an account, purchase or use our services, use our API or integrations, upload content, or otherwise interact with us.

For the purposes of this Privacy Policy, "PlagiarismSearch," "we," "us," or "our" refers, as applicable, to System Technology Online Spain SL. and System Tech Online USA Inc.

1. Who We Are

PlagiarismSearch.com and the services made available through the Website are operated by:

  • System Technology Online Spain SL., having its registered office at Calle Pintor Pérez Gil 2, b.46, 03540 Alicante, Spain; and
  • System Tech Online USA Inc., having its registered office at 5900 Balcones Dr, Ste 100, Austin, TX 78731, USA.

Depending on your billing location and the payment method selected at checkout, your contractual relationship and payment transaction are processed as follows:

  • System Tech Online USA Inc. 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. 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.

The role of a PlagiarismSearch entity in relation to personal data may depend on the context. For account administration, Website operation, billing, security, and our direct relationship with users, the applicable PlagiarismSearch entity may act as a data controller. Where a business, educational institution, or other organization submits personal data to the Service for processing on its behalf, PlagiarismSearch may act as a data processor subject to the applicable agreement with that customer.

2. Personal Data We Collect

We collect only the information reasonably necessary to operate, secure, support, and improve the Service and to fulfill our contractual and legal obligations.

Account and Contact Data

When you create or manage an account, contact us, or use certain features, we may collect information such as:

  • name;
  • email address;
  • phone number, where provided;
  • organization or institution, where applicable;
  • account identifiers and account settings;
  • language and regional preferences; and
  • billing country or other information required to determine the applicable service and payment terms.

Customer Content

When you use PlagiarismSearch, we process content that you choose to submit to the Service, which may include:

  • documents and text submitted for plagiarism or AI-content analysis;
  • files selected through supported cloud-storage integrations;
  • file names and related document metadata;
  • reference documents uploaded to private Storage;
  • URLs or other reference information submitted as part of the Service; and
  • reports and analysis results generated from submitted content.

Customer Content may contain personal data relating to you or other individuals. You are responsible for ensuring that you have an appropriate legal basis or other authority to submit personal data contained in your documents. You should avoid submitting sensitive or special-category personal data unless it is necessary for your use of the Service and you are legally permitted to do so.

Payment and Transaction Data

Payments are processed using third-party payment service providers. Depending on the payment method used, we may receive limited transaction and billing information such as the payment amount, currency, billing country, transaction identifier, payment status, and related records necessary for accounting, fraud prevention, and customer support.

Payment card credentials are handled through the applicable payment-processing environment. We do not request passport numbers, medical histories, or similar sensitive information for ordinary purchases of PlagiarismSearch services.

Technical and Usage Data

When you access the Website or Service, we may automatically receive technical and usage information, including:

  • IP address;
  • browser type and version;
  • operating system and device information;
  • date and time of access;
  • pages and features accessed;
  • referring pages or websites;
  • session and security information; and
  • server, application, and diagnostic logs.

We use this information to operate the Service, maintain security, detect fraud and abuse, diagnose technical problems, measure performance, and improve the user experience.

Information Received From Other Sources

We may also receive personal data from other sources when necessary to provide the Service. For example:

  • an organization administrator may provide account information for users within an organization;
  • payment providers may provide payment and transaction information;
  • Google may provide data that you authorize us to access through Google Drive or other supported Google integrations; and
  • service providers may provide technical, security, or analytics information related to the operation of the Website.

3. How We Use Personal Data

Depending on how you interact with PlagiarismSearch, we may use personal data to:

  • create and administer user accounts;
  • provide plagiarism detection, AI-content analysis, document comparison, Storage, reports, API access, and related features;
  • process files and Customer Content submitted to the Service;
  • process payments and maintain billing records;
  • provide customer and technical support;
  • investigate report results, technical problems, abuse, or security incidents;
  • authenticate users and protect accounts;
  • prevent fraud, misuse, unauthorized access, and attacks against our systems;
  • maintain, troubleshoot, develop, and improve the Service;
  • measure Website usage and performance;
  • communicate with users about their accounts, transactions, service changes, and support requests;
  • send marketing communications where permitted by applicable law and subject to applicable consent or opt-out requirements;
  • comply with legal, tax, accounting, regulatory, and law-enforcement obligations; and
  • establish, exercise, or defend legal claims.

4. Legal Bases for Processing

Where the General Data Protection Regulation (GDPR) or similar data-protection laws apply, we process personal data only where an appropriate legal basis exists.

Depending on the processing activity, our legal bases may include:

  • Performance of a contract: where processing is necessary to create or manage your account, provide the Service you requested, process a transaction, or perform our obligations to you.
  • Legitimate interests: where processing is reasonably necessary to operate and improve the Service, provide support, protect our systems, prevent fraud and abuse, maintain network and information security, or manage our business, provided that those interests are not overridden by your rights and freedoms.
  • Legal obligations: where processing is necessary to comply with applicable tax, accounting, regulatory, court, or other legal requirements.
  • Consent: where applicable law requires your consent, including for certain optional analytics, cookies, marketing activities, or integrations. You may withdraw consent at any time without affecting processing that was lawful before the withdrawal.

5. Customer Content, Ownership, and Private Storage

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

We process Customer Content only to the extent reasonably necessary to provide, operate, secure, support, and maintain the Service, comply with applicable legal obligations, or as otherwise authorized by the customer.

Customer Content is processed primarily through automated systems. Authorized personnel may access Customer Content where reasonably necessary to provide customer support, investigate a technical issue or report, maintain security, prevent abuse, comply with applicable law, or where access is otherwise authorized by the customer or the applicable agreement.

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

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

For organization accounts, members may be permitted to make their Storage documents searchable by other authorized members of the same organization. Such access depends on the applicable organization settings and permissions and does not make those documents part of a public or global customer database.

6. AI and Machine-Learning Training

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

Customer Content is processed for the services requested by the customer, including plagiarism detection, AI-content analysis, document comparison, reporting, Storage functionality, technical support, and related service operations.

7. Service Providers and Other Recipients

We may use third-party service providers where reasonably necessary to operate and support PlagiarismSearch. Depending on the Service and your use of it, these providers may include:

  • hosting, server, and infrastructure providers;
  • payment-processing and fraud-prevention providers;
  • analytics and Website-performance providers;
  • authentication and integration providers;
  • communications and customer-support service providers; and
  • professional advisers, auditors, insurers, and other business service providers where reasonably necessary.

We disclose only the information reasonably necessary for the relevant service or purpose.

We may also disclose personal data where required by applicable law, regulation, court order, or lawful request from a competent authority, or where reasonably necessary to protect the rights, safety, security, and integrity of PlagiarismSearch, our users, or others.

If PlagiarismSearch is involved in a merger, acquisition, financing, restructuring, or sale of all or part of its business or assets, relevant information may be transferred as part of that transaction subject to applicable data-protection requirements.

We do not sell Customer Content or make Customer Content available to unrelated customers for their independent use.

8. Analytics, Cookies, and Similar Technologies

PlagiarismSearch uses cookies and similar technologies to operate the Website, maintain sessions and security, remember preferences, process payments, and understand how the Website is used.

Our current Website environment may use:

  • strictly necessary cookies required for authentication, sessions, security, and core Website functions;
  • Stripe-related technologies used in connection with payment processing, security, and fraud prevention;
  • Google Analytics for Website analytics and performance measurement; and
  • Matomo for Website analytics and performance measurement.

Where required by applicable law, optional analytics and similar non-essential technologies are used only after the required consent has been obtained.

You can learn more about the cookies and similar technologies we use and manage your choices in our Cookie Policy.

9. Google Drive and Google API Data

PlagiarismSearch accesses Google user data only after the user has authorized the relevant Google integration.

When you choose to use Google Drive with PlagiarismSearch, we use read-only access to retrieve files that you choose to process through the Service. The Google Drive integration uses the https://www.googleapis.com/auth/drive.readonly scope.

Google Drive data is accessed only to provide the user-facing functionality requested by you, such as selecting and processing a document for plagiarism detection, AI-content analysis, or related PlagiarismSearch features.

Where required to provide the requested Service, PlagiarismSearch may extract and store the text of a file selected through Google Drive, together with the information necessary to process that file and generate the requested report.

PlagiarismSearch does not modify or delete the original file in your Google Drive through the read-only integration.

You may delete content stored in your PlagiarismSearch account in accordance with the available account controls and this Privacy Policy. Deleting content from PlagiarismSearch does not delete the original file stored in Google Drive. You may also revoke PlagiarismSearch's access to your Google account through your Google account permissions.

Google user data obtained through Google APIs is not used for advertising and is not used to train general-purpose or PlagiarismSearch AI or machine-learning models.

PlagiarismSearch's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

10. Where We Store and Process Data

Customer Content and service data may be stored using infrastructure located in the United States. Certain processing operations may also take place using infrastructure located in Europe.

As a result, personal data may be transferred to and processed in countries other than the country in which you are located.

Where applicable data-protection law requires additional safeguards for an international transfer, we use appropriate transfer mechanisms permitted by applicable law. Where an international transfer of personal data is subject to additional data-protection requirements, PlagiarismSearch applies the safeguards required by applicable law. Information about the safeguards applicable to a particular transfer may be requested using the contact details below.

You may contact us using the details below if you require additional information about the safeguards applicable to a particular international transfer.

11. Data Retention

We retain personal data only for as long as reasonably necessary for the purposes described in this Privacy Policy, to provide the Service, and to meet applicable legal, accounting, security, dispute-resolution, and regulatory requirements.

For reports and Customer Content:

  • reports generally remain available until they are deleted by the customer or removed under our applicable retention processes;
  • after approximately 30 days, reports may be moved to the Archive, where they remain accessible but certain report-editing functions may no longer be available; and
  • reports may be removed after five years under our long-term retention process.

Account, transaction, tax, security, and other operational records may be retained for different periods where necessary to comply with applicable law, prevent fraud, resolve disputes, enforce agreements, or maintain the security and integrity of the Service.

12. Deletion of Customer Content

Customers can delete applicable documents and reports through the available Service functionality or may contact us for assistance where necessary.

When a document or report is deleted, the corresponding active data is removed from the primary database.

If a document has also been indexed for private Storage search, it is marked as deleted in that search index and is removed from the index during the subsequent index rebuild.

Deletion does not require PlagiarismSearch to remove information that we are legally required to retain or limited records that must be retained to establish, exercise, or defend legal claims.

13. Security

We use technical and organizational measures designed to protect personal data and Customer Content against unauthorized access, misuse, loss, alteration, or disclosure.

These measures include HTTPS/TLS protection for data transmitted between users and PlagiarismSearch, access controls for production systems, and backup procedures.

No online service or method of electronic storage can guarantee absolute security. We therefore continuously review and maintain security measures appropriate to the nature of the Service and the data being processed.

If a personal data breach triggers notification obligations under applicable law or an applicable customer agreement, we will provide the required notifications in accordance with those obligations.

Additional information is available on our Privacy and Data Security page.

14. Your Privacy Rights

Depending on your location and applicable law, you may have rights in relation to your personal data.

Where the GDPR applies, these may include the right to:

  • request access to personal data we hold about you;
  • request correction of inaccurate or incomplete personal data;
  • request deletion of personal data where the legal requirements for deletion are met;
  • request restriction of processing in applicable circumstances;
  • receive certain personal data in a structured, commonly used, machine-readable format and request data portability where applicable;
  • object to processing based on legitimate interests in applicable circumstances;
  • object to direct marketing;
  • withdraw consent at any time where processing is based on consent, without affecting the lawfulness of processing carried out before withdrawal; and
  • lodge a complaint with a competent data-protection supervisory authority.

To exercise a privacy right, contact us at support@plagiarismsearch.com. We may need to verify your identity before completing a request.

Where GDPR response deadlines apply, we will respond to valid requests within the period required by applicable law.

15. Business, Educational, and Institutional Customers

If you use PlagiarismSearch through an employer, university, school, other educational institution, or another organization, that organization may control certain account information, permissions, Storage-sharing settings, submissions, and reports.

In those circumstances, the organization may act as the data controller for personal data submitted to PlagiarismSearch on its behalf, while PlagiarismSearch may act as a data processor for the relevant processing activities.

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. Separate enterprise terms may also apply.

If your account is managed by an organization and your question concerns the organization's own use of your personal data, you may also need to contact the relevant organization directly.

Certain services expressly selected by the customer, including Paper Analysis or other services that include human review, may require authorized specialists to access and review the submitted Customer Content in order to perform the requested service.

16. Children and Minors

The Service is not intended to be used in a manner that results in the unlawful collection of personal data from children or minors.

Where a parent, guardian, school, university, or other organization uses the Service in relation to a minor, that party is responsible for ensuring that it has the authority and legal basis required by applicable law.

If you believe that personal data relating to a child or minor has been submitted to us without the authorization required by applicable law, please contact us at support@plagiarismsearch.com.

17. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes to our Service, legal requirements, technology, or data-processing practices.

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