Gamecheck Browser Extension Privacy Notice

Effective date: 7 October 2026Last updated: 7 October 2026

This notice covers the Gamecheck Browser Extension for Google Chrome and Mozilla Firefox, on desktop and on Android.

This Privacy Notice applies only to the Gamecheck Browser Extension. Our Terms of Use, Subscription Terms and Privacy Notice cover the wider Gamecheck service. If they differ from this notice about data processed through the Gamecheck Browser Extension, this notice applies.

1. Who we are

Gamecheck Limited

Company number: 124930

Registered office: Madison Building Midtown, Queensway, Gibraltar GX11 1AA

Registered in: Gibraltar

Privacy contact: compliance@gamecheck.com

2. Introduction

This Privacy Notice explains how Gamecheck Limited ("we", "us", "our" or "Gamecheck") collects, uses, shares and protects your personal data when you use the Gamecheck Browser Extension.

The Gamecheck Browser Extension, for Google Chrome and Mozilla Firefox, helps users check whether an Online Casino game is real. When you start a check, the Gamecheck Browser Extension takes a screenshot of the game, along with key technical information from the web page that helps us confirm whether the game session is real. GamecheckAI, our own custom-built AI system, uses this to work out which game and supplier it is and to compare it with the supplier's approved list. To confirm authenticity, we may also share limited technical information about the game with the relevant supplier, but never your screenshot or your personal information. The result tells you whether the game is Real, Fake, could not be verified, is outside the suppliers we cover, or needs further assessment.

Gamecheck Limited is the data controller responsible for your personal data. We are registered in Gibraltar (Company number 124930). You can contact us about privacy matters at compliance@gamecheck.com.

We have not currently appointed a Data Protection Officer. This position is under review. We are also assessing whether the appointment of an EU GDPR representative under Article 27 is required.

3. Personal data we collect

We collect the following categories of personal data when you use the Gamecheck Browser Extension.

3.1 Account data

Username, email address, date of birth, profile photo (if you add one), preferred language, IP address, browser type and version, time zone, timestamps, Gamecheck session ID, account status, subscription status, security logs and access logs.

3.2 Game session data

The Online Casino's website name, key technical information from the web page that helps us confirm whether the game session is real, the game name, the supplier name, the time of the check, your time zone, a screenshot of the game with personal details already hidden (see section 5.2), the result of the check, whether the game matched the supplier's approved list, and our internal records of the check.

The technical information we take never includes your login details, session codes or anything else that could identify you.

3.3 Payment and billing data

Subscription plan, payment status, billing frequency, invoice records, transaction metadata, payment provider reference, and payment method type. We do not store full payment card details.

3.4 Technical, security, and analytics data

IP address, browser type and version, Gamecheck Browser Extension version, error logs, access logs, and basic usage events, such as when you open a website link in one of our messages. On Firefox, we only record these usage events if you allow it, either when you install the Gamecheck Browser Extension or later in Firefox's add-on settings. The Gamecheck Browser Extension does not use cookies, advertising identifiers or tracking identifiers, and it does not include any third-party analytics or advertising tools, such as Google Analytics, Meta Pixel or Microsoft Clarity.

3.5 Support requests

If you use Report an issue, we collect the type of problem, your description, the Online Casino website it relates to (we fill this in from the page you are on, and you can change it) and any images or videos you attach. We use this only to look into and fix the problem you report. Attachments are only sent to us when you press Send. If you close the form without sending it, nothing is sent.

4. Data we do not intentionally collect

We do not intentionally collect: phone numbers, full names (beyond standard registration), device IDs, Online Casino account passwords, Online Casino cookies, HTTP headers, POST bodies, response bodies, bet or win/loss information, personal messages, chat windows, account balances, financial information inside Online Casino accounts, personal data of third parties, or unrelated browser tab content.

5. How we collect your data

The Gamecheck Browser Extension only collects information when you start a check, and it does as much of the work as possible on your own device.

5.1 Starting a check

When you start a check, the Gamecheck Browser Extension takes key technical information from the web page that helps us confirm whether the game session is real. It does not watch or record your network traffic, and it stops once it has what it needs for that check.

To take the screenshot, the Gamecheck Browser Extension captures the visible page and cuts it down to the game area. Only the game area is ever sent to us, never your whole screen or your other tabs. Before you send it, you will see a preview with your personal details already hidden.

5.2 How your screenshot is protected

Before your screenshot leaves your device, the Gamecheck Browser Extension automatically hides any personal details in it. This is done entirely by software on your own device, with no person involved. This is how it works, on desktop and on Android alike:

  1. The Gamecheck Browser Extension holds the screenshot in your browser's temporary memory. It is not saved as a file on your device.
  2. It scans the image automatically, reading the text on the page and any text shown inside the game itself.
  3. It covers anything personal or financial it finds with a solid black box. This includes your email address and username, any other email addresses and phone numbers, card numbers and bank account numbers (IBANs), crypto wallet addresses, postcodes, account and user IDs, and money amounts, including your balance, bets and wins.
  4. The black boxes are fixed into the image. They are permanent and cannot be removed.
  5. Only the masked copy is sent to us. The original is deleted from your browser's memory as soon as the check is sent or cancelled, or when you close the tab or the browser.

If the automatic scan cannot finish for any reason, we do not send a screenshot at all, and the check carries on without one. If you check the same game again, no new screenshot is sent.

5.3 How we store and use your screenshot

Your screenshot is processed by GamecheckAI, our own custom-built AI system, which uses it to help confirm whether the game is real. It is never shared with suppliers or Online Casinos. In limited cases, such as a dispute about a result or a quality check, a trained member of our team may also look at it, without being told whose screenshot it is. Section 8 explains when this can happen and how your screenshot is protected.

We store the masked copy securely on our servers in Frankfurt, Germany, for six months, so that you can view it again in the message that gives you your result. After six months it is permanently deleted and will no longer appear in your messages. Because it is linked to your account, we treat it as personal data.

You can ask us to delete your screenshots sooner, or any other personal data we hold about you, at any time by emailing compliance@gamecheck.com. Section 14 explains how.

5.4 What the Gamecheck Browser Extension does in the background

To spot Online Casino games, the Gamecheck Browser Extension runs on the pages you visit. This happens on your device, and nothing about those pages is sent to us unless you start a check. On Firefox for Android, this is also how the Gamecheck button appears on Online Casino pages.

To work out which Online Casino a game was opened from, the Gamecheck Browser Extension remembers the names of the last five websites you visited in each tab. It keeps only the website name, not the full address, and deletes it when you close the tab or the browser.

When you are signed in, the Gamecheck Browser Extension checks with us every five minutes for new messages so that it can let you know about them. On Android, it may also check how many checks you have left when a page loads. Neither of these sends us the pages you visit.

5.5 Information kept on your device

The Gamecheck Browser Extension keeps some information in your browser's own extension storage so that it can work. This information stays on your device and is not sent to us.

Until you sign out: the codes that keep you signed in, your account details (email address, username, date of birth, profile photo and language), and your plan and how many checks you have left.

Until you remove the Gamecheck Browser Extension: your settings, such as whether notifications are muted and where the Gamecheck button sits on screen, and whether you have agreed to this notice and watched the introduction video.

Only while needed: the screenshot being checked, the last five website names in each tab, and the technical information for your current check, kept for no more than one hour. These are deleted when you close the tab or the browser.

Removing the Gamecheck Browser Extension deletes all of this.

6. Why we use your data

We process your personal data for the following purposes.

6.1 Providing the service

Creating and managing your account; verifying login and security; enforcing device/session limits; providing free trial and subscription access; processing payments and invoices.

6.2 Core Gamecheck Browser Extension functions

Capturing screenshots when you start a check and automatically hiding personal details in them; taking key technical information from the web page; identifying game suppliers; matching games against suppliers' approved lists; sharing limited technical information about the game, which contains no personal information, with suppliers to confirm authenticity; confirming whether game sessions are real; returning result statuses.

6.3 Investigations and integrity

Conducting internal investigations into misuse of the service; detecting fraudulent or invalid screenshots using GamecheckAI; detecting account sharing or misuse; responding to disputes; correcting or withdrawing results; checking that results are accurate, including human review of screenshots in the limited cases described in section 8; maintaining evidence files.

6.4 Security and compliance

Preventing abuse, hacking, and fraud; complying with legal, tax, accounting, and regulatory obligations; maintaining security and access logs; protecting our legal rights.

6.5 Communications and improvement

Sending service messages (account, subscription, security, results, outages, legal notices); analysing website and Gamecheck Browser Extension usage; improving service performance.

7. Lawful bases for processing

We rely on the following lawful bases under the Gibraltar GDPR.

7.1 Contract

Processing of account data, screenshots, technical game session information, supplier information, result data and payment or subscription information is necessary to provide the service to you.

7.2 Legitimate interests

Fraud prevention, account security, misuse detection, game verification, internal investigations, service improvement, dispute handling, checking the accuracy of results (including human review of screenshots, as described in section 8), evidence retention, and protection of our legal rights.

7.3 Legal obligation

Tax, accounting, compliance, consumer law, data protection, legal claims, and regulatory obligations.

7.4 Consent

Optional usage data in the Gamecheck Browser Extension on Firefox, the immediate supply of digital services, and AI-assisted analysis where consent is legally required. You can withdraw your consent at any time by emailing compliance@gamecheck.com or by removing the Gamecheck Browser Extension.

8. AI-assisted analysis and human review

We use GamecheckAI, our own custom-built AI system, to analyse screenshots, identify games and suppliers, and support our checks.

GamecheckAI only ever receives the masked copy of your screenshot described in section 5.2. We do not use your screenshots to train general AI models.

In limited cases, a trained member of our team may look at a screenshot. We only do this:

  1. to resolve a dispute or complaint about the result of a check; or
  2. to carry out quality checks on a sample of results, so that we can confirm that GamecheckAI's results are accurate, correct any that are wrong and make GamecheckAI more accurate.

Whenever a person looks at a screenshot, the following safeguards apply:

  1. Before the reviewer sees the screenshot, our systems check it again automatically and black out any personal details that may have been missed on your device.
  2. The reviewer sees the screenshot together with the result of the check and technical information about the game. They are not shown your name, username, email address or any other account details, so they are not told whose screenshot it is.
  3. Reviewers are members of our own team. They are trained in data protection and bound by confidentiality. Access is limited to the people who need it for this work and is protected by the security measures described in section 12.
  4. Human review does not change who we share screenshots with or how long we keep them. Screenshots are never shared with suppliers or Online Casinos, are never published, and are permanently deleted after six months.
  5. Because we can still link a screenshot to the check it came from, we continue to treat it as personal data, even though the reviewer is not told whose it is.

We only review screenshots sent on or after 7 October 2026. A screenshot sent before that date is never viewed by a person unless you ask us to look at it, for example as part of a dispute you raise.

On Google Chrome, a person will only look at your screenshot if you ask us to (for example, as part of a dispute you raise), where it is needed to investigate fraud or misuse, or where the law requires it. Screenshots sent from Google Chrome are not used for quality checks.

We carry out human review on the basis of our legitimate interests in resolving disputes and making sure our results are accurate (see section 7). You have the right to object to this processing, as explained in section 14.

9. Automated decision-making

We use automated matching against suppliers' approved lists and the technical information taken from the web page to determine game status. The status messages we provide are informational only and are not intended to produce legal effects.

Where automated processing materially affects your account (for example, fraud detection or account suspension), you can ask for the decision to be reviewed by a member of our team by contacting us at compliance@gamecheck.com. The review uses your account records and the records of your checks. If a screenshot needs to be looked at, this is done separately by a reviewer who is not told whose it is, as described in section 8.

10. Who we share your data with

We may share your personal data with:

10.1 Internal teams

Our investigation, legal, compliance, senior management, technical and security teams, where they need access to do their work. Only trained reviewers can view screenshots, in the limited cases and with the safeguards described in section 8, and they are not told whose screenshot it is.

10.2 Service providers and processors

AWS (hosting), Cloudflare (security/CDN), Stripe (card payments), NOWPayments (crypto payments) and other email, logging, monitoring, support, security and professional advisory vendors.

10.3 Suppliers

To confirm game authenticity, we may share limited technical information about the game with the relevant supplier. This information is used solely for authenticity verification and does not include your personal information. It never includes your screenshot, your name, username, email address, IP address or account details.

10.4 Legal and regulatory bodies

Courts, regulators, law enforcement, and professional advisers where required by law or to defend legal claims.

We do not sell your personal data.

11. International transfers

Primary screenshot storage is in AWS Frankfurt, Germany. We aim to keep your data within Gibraltar, the United Kingdom, and/or the European Economic Area where possible.

Where data is transferred outside these jurisdictions (for example, to service providers such as Stripe, which may process data in the United States or other countries), we ensure appropriate safeguards are in place, including Standard Contractual Clauses, data processing agreements, transfer risk assessments and adequacy mechanisms.

12. Data security

We take the security of your data seriously. We are ISO 27001 certified (Certificate IS 832990) and implement the following measures:

  1. encryption at rest and in transit for screenshots, technical game session information and evidence files;
  2. TLS/HTTPS for all data in transit;
  3. role-based access controls and least-privilege access;
  4. multi-factor authentication for all internal systems accessing personal data;
  5. access logs, audit trails, periodic access review, and breach procedures;
  6. penetration testing, backup and restore procedures, and secure key management.

13. Data retention

We retain your personal data only as long as necessary. Our key retention periods are:

  1. screenshots: we only ever hold the masked copy, which we store for six months so that you can view it with your result, and then permanently delete;
  2. evidence files (records of a check, such as the technical information, supplier responses and the result, but never screenshots): approximately 3 to 6 months;
  3. technical game session information: kept in anonymised form; any link to a user is removed, anonymised or pseudonymised once the check, or any investigation into it, has closed;
  4. account data: retained while your account is active and for a reasonable period after closure;
  5. payment records: retained as required for legal, tax, accounting, AML, audit, and compliance purposes;
  6. support requests: kept for as long as we need to resolve your request, and then deleted;
  7. information kept on your device: see section 5.5;
  8. backups: deleted in accordance with our backup deletion cycle.

14. Your rights

Under the Gibraltar GDPR, you have the following rights in relation to your personal data:

  1. the right to access your personal data and obtain a copy;
  2. the right to rectification (correction) of inaccurate data;
  3. the right to erasure (deletion) of your data in certain circumstances;
  4. the right to restriction of processing;
  5. the right to object to processing based on legitimate interests;
  6. the right to object to direct marketing;
  7. the right to data portability;
  8. the right to withdraw consent at any time (where processing is based on consent);
  9. the right to information about automated decision-making; and
  10. the right to lodge a complaint with the Gibraltar Regulatory Authority or another competent supervisory authority.

To exercise any of these rights, please contact us at compliance@gamecheck.com. We will respond within one calendar month (which may be extended by up to two months for complex requests).

Asking us to delete your data

Under data protection law, including the Gibraltar GDPR, you have the right to ask us to delete the personal data we hold about you. To do this, email compliance@gamecheck.com. This covers your account, your screenshots, your game checks and anything you have sent us through Report an issue. To help us find your account quickly, please email us from the address you signed up with.

We will reply within one calendar month and let you know once your data has been deleted. The law requires us to keep some information for longer, such as payment, tax and accounting records and records we need for an active dispute or legal claim. If we cannot delete something, we will tell you what it is and why.

You can stop the Gamecheck Browser Extension collecting anything at any time by signing out or removing it. Removing it also deletes everything it keeps on your device. In Firefox, the data permissions you agree to when installing can only be withdrawn by removing the Gamecheck Browser Extension.

15. Cookies
