Privacy Policy
This policy describes how Calcendo may process information when you browse the site, use calculators, manage preferences, or interact with advertising. The actual services enabled on a given date depend on the site's production configuration.
1. Calculator inputs and use of the site
Many standard calculations run in your browser. Inputs entered into a browser-based tool are used to produce the result displayed to you. Some optional features, including AI-assisted explanations or API-backed tools if enabled, may send the relevant prompt or input to the service provider needed to deliver that feature. Do not enter passwords, government identification numbers, payment card information, confidential business records, or other sensitive data into a general calculator.
2. Cookies and local storage
Cookies and similar technologies can be used to remember preferences, support essential site functions, measure performance, prevent abuse, or deliver and measure advertising. The region preference may be stored in a cookie named calcendo_region. Depending on which services are enabled, third-party providers may set or read their own cookies or use local storage. Browser settings can help you inspect or remove stored information, but blocking essential storage may affect some features.
Where applicable law requires consent for non-essential cookies or similar technologies, those technologies must not be enabled before the required choice has been obtained. A privacy policy is not a consent mechanism. Calcendo's advertising script remains disabled unless advertising and consent-readiness are explicitly configured; that configuration flag alone does not establish that a certified consent platform is integrated. Use the consent controls provided by the active consent platform when available, and review browser settings if you need to manage stored data.
3. Google advertising and AdSense
Calcendo may display advertisements provided by Google AdSense or other advertising partners when advertising is enabled. Google and its partners may use cookies, device identifiers, IP addresses, browser information, and activity signals to deliver, limit, personalise, or measure ads, subject to applicable settings and consent. Personalised advertising can involve the use of information about activity across sites or services. Ads may be contextual or non-personalised where supported and appropriate.
For visitors in the European Economic Area, the United Kingdom, and Switzerland, Google publisher products require an appropriate Google-certified consent management platform integrated with the IAB Transparency and Consent Framework when serving personalised ads. The site's operator must configure a suitable consent solution and ensure advertising tags respect the choices that apply to each visitor. A privacy notice alone does not collect consent and does not prove that a consent mechanism is correctly implemented. You may also review Google's published privacy information and ad-personalisation controls.
4. Consent and your choices
Where required, a suitable consent management platform must explain relevant purposes and providers and offer practical ways to accept, reject, or manage optional purposes before the associated technologies run. The site operator is responsible for integrating and verifying that platform before enabling advertising for affected visitors. When such controls are available, you can revisit or withdraw consent through them. Some essential processing may continue where permitted because it is necessary to provide the service, protect security, or comply with law.
5. Hosting, technical data, and third parties
Hosting, security, analytics, advertising, and optional feature providers may process technical information such as request timestamps, IP address, browser type, requested URLs, and error details as part of their services. The specific providers and data flows depend on the features actually enabled. We do not promise that all information remains on your device or that the site never uses telemetry. Service providers may process data in other countries under their applicable terms and safeguards.
6. Retention and security
Retention depends on the purpose, the provider involved, legal requirements, and operational needs. Preference storage may remain until it expires or you remove it. Server and security logs are retained according to the hosting configuration. No website can guarantee absolute security, but appropriate technical and organisational safeguards should be used to reduce the risk of unauthorised access, loss, or misuse.
7. Your rights and questions
Depending on your location, you may have rights to request access, correction, deletion, restriction, objection, or portability of personal information, and to complain to a relevant data-protection authority. These rights are subject to applicable law and exceptions. To ask a question or make a privacy request, contact [email protected]. Please do not send passwords or sensitive personal information in an ordinary email.
8. Policy updates
This policy may be updated when the site changes its functionality, providers, advertising configuration, or legal obligations. We update this policy when material changes are made to the site's features, service providers, advertising settings, or legal obligations. The details in this notice should be read alongside the services and consent choices actually presented to you.
