What is my IP address and what does it show?

Your IP address is a number assigned by your provider. Whoer shows it together with rough location, ISP name and ASN.

How do I find my IP address and location?

Open Whoer.net in your browser. The first screen shows your IP, country or city, ISP and basic connection info.

What does “see leaks” mean?

Leaks occur when real IP or DNS requests become visible outside a VPN. Whoer runs DNS and WebRTC leak tests and highlights exposures.

Does a VPN change the IP I see?

If your VPN is working, you’ll see its IP. If not, tests may show mismatches or leaks.

Is it safe to use Whoer?

Whoer shows only technical data your browser already sends: IP, headers, basic signals. No personal data or software required.

Privacy Policy

1) Who we are and how to contact us

Controller: WHOIX LTD, a private limited liability company registered in Cyprus with company number HE 356927.
Registered address: Georgiou Zolota 5A, Strovolos, Nicosia, Cyprus.
Email: [email protected]

We have not appointed a Data Protection Officer and are not required to do so under Article 37 GDPR given the nature and scale of our processing. No separate EU/UK representative is required because the controller is established in the EU (Cyprus).

2) Scope

whoer.net and subdomains;
diagnostic tools (IP lookup, VPN/Proxy check, browser fingerprint page, DNS/WebRTC leak tests, IP blacklist checks, basic port scan);
public APIs and embeddable widgets;
advertising‑supported content (e.g., Google AdSense; Mediavine).

Third‑party sites and services linked from the Website are governed by their own policies.

3) Definitions

“Personal data” (GDPR) / “Personal information” (US) means information related to an identified or identifiable natural person. “Cookies” includes similar local storage technologies (e.g., localStorage). “Targeted advertising” (US) refers to cross‑context behavioral advertising.

4) Information we process

A. Information you provide

Support / feedback you send to us.
API inputs required to run diagnostics (e.g., a host you choose to scan).

Do not include unnecessary personal data in free‑text fields.

B. Information collected automatically

Identifiers & device info: IP address, coarse geolocation inferred from IP, user‑agent, OS and browser type/version, language, device type.
Website activity: referrers/exit pages, timestamps, URL parameters, error codes, performance metrics.
Networking signals (tool‑specific): e.g., TLS/HTTP signatures (including ALPN/H2 status), WebRTC candidates for leak tests, DNS resolver behavior, port reachability for the target you specify, VPN/Proxy heuristics and similar diagnostic telemetry.
Cookies/local storage: see Section 11.

About the tools. Some tests necessarily trigger network requests to deliver the results you initiate. For port checks/scans you start, our systems may query the target you provide solely to return the result. Do not scan hosts or networks without authorization. You are responsible for choosing targets and complying with applicable law and acceptable‑use policies.

C. Information from partners/third parties

Advertising & measurement signals (Google; Mediavine and its partners) — see Sections 12–13.
Security/abuse prevention: threat intelligence or IP‑risk lists to prevent abuse and ensure service integrity.

We do not attempt to associate diagnostic signals with a real‑world identity unless you contact us and provide that context (e.g., for support).

5) Purposes of processing

Provide the Website/tools and return results you initiate;
Operate, maintain, and improve performance, reliability, and security;
Detect, prevent, and respond to fraud, abuse, and attacks;
Measure and optimize content, features, and advertising;
Comply with legal obligations and enforce terms;
Communicate with you (support, service notices).

6) Legal bases (EU/UK/CH)

Consent for storing/reading cookies or similar tech (where required) and for personalized advertising;
Legitimate interests (Art. 6(1)(f)) for security, fraud prevention, diagnostics, service improvement, and non‑personalized ads/measurement;
Contract (Art. 6(1)(b)) to deliver results you request via tools/APIs;
Legal obligation (Art. 6(1)(c)) where processing is required by law or competent authorities.

You may withdraw consent at any time via our Consent & Cookie Settings.

7) Automated Decision‑Making and Profiling

Whoer.net does not use automated decision‑making that produces legal effects concerning you or similarly significantly affects you within the meaning of GDPR Articles 13(2)(f) and 14(2)(g).

Advertising partners. Where you consent to personalized advertising (see AdSense and Mediavine sections), our partners may use automated processing to assign you to audience segments based on cookies or similar identifiers, device/browser information, and your interactions with pages and ads. The consequence is the delivery of ads that are more relevant to your interests. You can withdraw consent or opt out at any time via the consent banner/settings and the industry tools linked in this Policy.

8) Is Providing Personal Data Mandatory?

Website access and diagnostics. Certain technical data (e.g., IP address, basic device/browser information) are generated by your device and are necessary to establish a connection and return the results you request. If this data is not available, the Website cannot function correctly.
Cookies/consent. Non‑essential cookies (e.g., for personalized ads/analytics) are not mandatory and require your consent where applicable. Refusing them may limit personalization or certain measurements but the core Website will still be available.
Support inquiries. If you contact us, providing contact details and relevant context is necessary to process your request; otherwise we may be unable to respond or resolve the issue.
API/tests you initiate. If you do not provide the parameters (e.g., a target host) required for a test, we cannot run that test and return a result.

Unless expressly stated otherwise, providing personal data is not a statutory or contractual requirement; however, not providing certain information may prevent us from delivering specific features you request.

10) Data retention

Web & security logs: retained up to 90 days (longer if required for incident investigation or legal claims).
Diagnostic outputs: kept transiently to deliver results and troubleshoot (longer if tied to a support ticket).
Advertising/measurement data: per our partners’ retention schedules and applicable law.
Aggregated, de‑identified metrics: may be retained without time limit.

11) Cookies and similar technologies

We use first‑party and third‑party cookies, local storage, tags/pixels, and similar technologies to operate the Website, remember preferences, measure performance, prevent fraud, and support advertising.

Consent & controls: manage via our Consent & Cookie Settings and your browser/device settings (blocking/deleting cookies may limit features).
EU/UK/CH: we use a Google‑certified Consent Management Platform (CMP) integrated with IAB Europe’s TCF 2.2 where required, and implement Google’s Consent Mode (v2) for AdSense/Ads signals.

You can reopen the consent banner at any time via the Consent & Cookie Settings link to review or withdraw your choices (including “reject all”).

13) Mediavine Programmatic Advertising

The following disclosure is provided at Mediavine’s request and included verbatim:

Mediavine Programmatic Advertising (Ver 1.1)

The Website works with Mediavine to manage third-party interest-based advertising appearing on the Website. Mediavine serves content and advertisements when you visit the Website, which may use first and third-party cookies. A cookie is a small text file which is sent to your computer or mobile device (referred to in this policy as a “device”) by the web server so that a website can remember some information about your browsing activity on the Website.

First party cookies are created by the website that you are visiting. A third-party cookie is frequently used in behavioral advertising and analytics and is created by a domain other than the website you are visiting. Third-party cookies, tags, pixels, beacons and other similar technologies (collectively, “Tags”) may be placed on the Website to monitor interaction with advertising content and to target and optimize advertising. Each internet browser has functionality so that you can block both first and third-party cookies and clear your browser’s cache. The "help" feature of the menu bar on most browsers will tell you how to stop accepting new cookies, how to receive notification of new cookies, how to disable existing cookies and how to clear your browser’s cache. For more information about cookies and how to disable them, you can consult the information at All About Cookies.

Without cookies you may not be able to take full advantage of the Website content and features. Please note that rejecting cookies does not mean that you will no longer see ads when you visit our Site. In the event you opt-out, you will still see non-personalized advertisements on the Website.

The Website collects the following data using a cookie when serving personalized ads:

IP Address
Operating System type
Operating System version
Device Type
Language of the website
Web browser type
Email (in hashed form)

Mediavine Partners (companies listed below with whom Mediavine shares data) may also use this data to link to other end user information the partner has independently collected to deliver targeted advertisements. Mediavine Partners may also separately collect data about end users from other sources, such as advertising IDs or pixels, and link that data to data collected from Mediavine publishers in order to provide interest-based advertising across your online experience, including devices, browsers and apps. This data includes usage data, cookie information, device information, information about interactions between users and advertisements and websites, geolocation data, traffic data, and information about a visitor’s referral source to a particular website. Mediavine Partners may also create unique IDs to create audience segments, which are used to provide targeted advertising.

If you would like more information about this practice and to know your choices to opt-in or opt-out of this data collection, please visit National Advertising Initiative opt out page. You may also visit Digital Advertising Alliance website and Network Advertising Initiative website to learn more information about interest-based advertising. You may download the AppChoices app at Digital Advertising Alliance’s AppChoices app to opt out in connection with mobile apps, or use the platform controls on your mobile device to opt out.
