This Cookie Policy explains how WT Free Tools uses cookies and similar storage or access technologies when you visit our website, use our calculators and online tools, or interact with a WT Free Tools tool embedded on another website. It should be read together with our Privacy Policy. The exact technologies active on a visit can depend on your country, consent choices, browser, device, and services enabled on the page.
1. What cookies and similar technologies are
A cookie is a small piece of data stored in or read from your browser by a website or service. Similar storage and access technologies can include local storage, session storage, pixels, tags, scripts, SDKs, device or advertising identifiers, and related technologies that remember information or recognize a browser or device.
Some technologies are first-party, meaning they are associated with WT Free Tools, while others are operated by third parties such as advertising, analytics, security, content-delivery, payment, or CAPTCHA providers.
2. Why WT Free Tools may use them
We may use cookies and similar technologies to keep the Service working, protect it from fraud and abuse, remember privacy and language preferences, maintain sessions, measure performance, diagnose errors, understand how tools are used, support advertising, measure advertising, and comply with your consent or opt-out choices.
Optional advertising cookies are not required merely to perform the core arithmetic of a basic calculator. However, pages can contain advertising, analytics, or other third-party services that use separate technologies subject to consent or opt-out requirements where applicable.
3. Strictly necessary technologies
Strictly necessary technologies support security, fraud prevention, load balancing, session integrity, consent records, privacy choices, and features you explicitly request. Where applicable law permits, these technologies may operate without optional consent because the requested function or privacy control cannot reasonably work without them.
Blocking all site storage can prevent parts of the website, privacy controls, account security, or certain tools from working correctly.
4. Preference and functional technologies
Preference technologies can remember choices such as language, interface settings, display preferences, recently used tool settings, or whether you already answered a notice. Depending on the jurisdiction and the specific purpose, this storage may be necessary to deliver a feature you request or may require consent.
5. Analytics and performance
Analytics and performance technologies can help us understand page loading, tool usage, navigation, and technical failures. Information can include page views, approximate region, browser or device information, timestamps, diagnostic events, and interaction measurements.
If a particular analytics technology requires consent in your jurisdiction, it should remain disabled until the required permission is obtained. The exact analytics services enabled on WT Free Tools should be reflected in the live consent panel and Privacy Policy.
6. Advertising and Google AdSense
WT Free Tools may use Google AdSense or other advertising services to help fund free tools. Google states that its advertising products can use cookies and similar technologies to serve and render ads, limit the number of times an ad is shown, prevent fraud and abuse, measure advertising, and—when permitted by your choices and applicable law—personalize advertising.
AdSense advertising cookies may be associated with Google domains or third-party domains such as doubleclick.net, and Google may use first-party advertising cookies on publisher sites. Cookie names, purposes, and durations can change as products change, so Google's current cookie documentation should be treated as the provider-level reference.
Depending on configuration and your choices, advertising providers may receive technical information such as IP address, browser/device details, approximate location, page context, advertising identifiers, and ad interaction data.
7. Personalized and non-personalized ads
Personalized advertising may use interests, previous activity, or identifiers to select or measure ads when applicable law and your choices allow it. Non-personalized or contextual advertising does not use a personalized profile to select an ad, but advertising providers may still use cookies or similar technologies for basic ad delivery, frequency capping, aggregated reporting, security, and fraud prevention where legally permitted.
Rejecting personalized advertising therefore does not necessarily mean that no ads will appear or that every advertising technology is disabled.
8. EEA, United Kingdom, and Switzerland
For users in the European Economic Area, the United Kingdom, and Switzerland, Google requires publishers using its advertising products to make required disclosures and obtain consent for cookies or other local storage and personal-data uses where required. Google also requires a Google-certified consent management platform integrated with the IAB Transparency and Consent Framework for certain publisher advertising uses in these regions.
Where consent is legally required, non-essential advertising or analytics technologies should not be activated before the required consent. Users should be able to accept, reject, or manage available choices and later change or withdraw consent.
Rejecting optional cookies should not prevent access to core WT Free Tools calculators that do not technically require those cookies, although advertising, analytics, personalization, or optional features may operate differently.
9. U.S. privacy choices, sale/share, and targeted advertising
WT Free Tools does not sell personal information for money. However, certain U.S. state laws may classify disclosures of online identifiers or browsing activity to advertising partners for cross-context behavioral or targeted advertising as a “sale,” “sharing,” or targeted advertising even when no money is exchanged.
Where those laws apply to WT Free Tools, eligible users may opt out through the Your Privacy Choices mechanism. Where required, a valid Global Privacy Control signal is treated as an opt-out request for the browser or device sending the signal.
An advertising opt-out may result in contextual or otherwise restricted advertising rather than the complete removal of ads.
10. Embedded tools and third-party content
A WT Free Tools tool embedded on another website can cause a visitor's browser to connect to WT Free Tools and may create necessary technical requests. The embedding website may separately use its own cookies and tracking technologies; its privacy and cookie policies apply to those independent practices.
Third-party content, CAPTCHA, security services, video players, fonts, payment services, or other integrations may use their own cookies or similar technologies when enabled.
11. Local browser tools and sensitive calculator inputs
Many WT Free Tools calculators and file utilities are designed to perform their core calculation or transformation in the browser. When a tool is expressly described as local or browser-based, the working file or input is intended to remain on your device for that operation unless the tool states otherwise.
Local processing does not mean the page makes no network requests; advertising, analytics, security, consent, or page-delivery services may make separate requests. Health, pregnancy, financial, investment, and other sensitive calculator values should not be passed to advertising partners merely because you entered them into a calculator. Before publishing this Policy, the site operator must verify that the implementation matches this statement.
12. Cookie duration and live inventory
Some cookies last only for a browsing session. Persistent cookies can remain until a stated expiration date or until you delete them. Duration varies according to purpose, provider, browser, consent record, and product configuration.
Because third-party providers can change cookie names and lifetimes, the strongest implementation is to maintain a current cookie inventory in the live CMP showing the provider, purpose, category, and duration of technologies actually used. WT Free Tools should periodically rescan and review that inventory.
13. Managing cookies, consent, and browser settings
Where a cookie or consent control is available, you can use it to accept or reject optional categories and to change or withdraw a previous choice. Withdrawal applies to future processing and does not invalidate processing that was lawful before withdrawal.
Most browsers also allow you to block or delete cookies and site data, restrict third-party cookies, or enable tracking protection. Mobile devices may provide advertising-ID and tracking controls. Blocking all storage can affect necessary features. Deleting cookies may also erase the stored record of your previous privacy choice.
14. Do Not Track, GPC, children, updates, and contact
Browser Do Not Track signals are not interpreted consistently across the industry, and we may not respond unless applicable law requires it. Global Privacy Control is a distinct privacy preference signal. Where applicable law requires recognition of a valid GPC signal, WT Free Tools honors it for the browser or device from which it is received.
WT Free Tools is not directed to children under 13, and tracking or advertising involving children can be subject to additional restrictions or higher age thresholds in some jurisdictions.
We may update this Policy when providers, advertising, analytics, tools, law, or our technical configuration changes. For questions, use the contact details on the WT Free Tools Contact page and review our Privacy Policy, Terms of Use, and Your Privacy Choices page.
