Cookie Policy & Consent Framework

1. What Are Cookies & Browser Storage Technologies?

Cookies are small alphanumeric text files placed onto your computer, smartphone, or tablet by websites that you visit. They are widely utilized by web properties to make websites function efficiently, remember preferences across sessions, and provide structured reporting data to site operators.

In addition to HTTP cookies, Homecalpro utilizes modern HTML5 browser storage mechanisms, primarily window.localStorage. Local storage permits key-value data to persist securely on your device without transmitting data back and forth with every HTTP server request.

2. Categories of Storage & Cookies Deployed on Homecalpro

We classify all storage tokens and cookies deployed across Homecalpro into three clear functional categories:

3. Google AdSense & Third-Party Advertising Disclosures

Homecalpro partners with Google AdSense to display advertisements that finance the free maintenance, engineering calibration, and server hosting of our universal calculation library. Google and certified third-party ad networks operate on our platform under the official Google AdSense Program Policies and Google Publisher Policies.

Important advertising disclosures required by Google:

• Third-Party Vendors: Third-party vendors, including Google, use cookies to serve advertisements based on a user's prior visits to Homecalpro or other websites on the Internet.
• Advertising Cookies (DoubleClick DART): Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to our sites and/or other sites on the Internet.
• Opt-Out Options: Users may opt out of personalized advertising by visiting Google My Ad Center or Google Ads Settings. Alternatively, users can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the AboutAds Consumer Choices page.
• Google Partner Disclosure: Learn more about how Google processes information by reading How Google uses information from sites or apps that use our services.

4. European User Consent (GDPR, ePrivacy & Google Consent Mode v2)

For visitors accessing Homecalpro from the European Economic Area (EEA), the United Kingdom, or Switzerland, we abide strictly by the Google EU User Consent Policy and the IAB Europe Transparency & Consent Framework (TCF v2.2):

• Explicit Prior Consent: No non-essential advertising or analytics cookies are set prior to affirmative consent via our interactive Consent Management Platform (CMP).
• Consent Mode v2 Telemetry: We broadcast Google Consent Mode v2 signals (ad_storage, ad_user_data, ad_personalization, analytics_storage). If you reject cookies, Google tags execute in cookieless ping mode without writing or reading tracking identifiers.
• Revoking Consent: You may change or withdraw your cookie consent at any time by clearing your browser cookies or clicking the consent preferences trigger in our footer.

5. California & US State Privacy Rights (CCPA / CPRA Notice)

Under the California Consumer Privacy Act (CCPA) as amended by the California Privacy Rights Act (CPRA), California residents possess statutory rights regarding personal data processing:

• No Direct Data Selling: Homecalpro does not sell, rent, or lease personal information or calculation records for monetary consideration.
• Advertising Cookie Sharing: To the extent that third-party advertising cookies are construed as "sharing" personal information under California law, you may opt out via our footer links or by broadcasting the Global Privacy Control (GPC) signal from a supported web browser.
