Privacy Policy

1. Our Core Privacy Commitment: 100% Client-Side Processing

At Shiplap Calculator, we believe utility tools should be useful without compromising personal privacy. All mathematical room calculations, wall dimensions, door and window opening sizes, wood species selections, and pricing estimates are processed exclusively client-side in your local web browser.

We do not transmit, log, store, or sell your room dimensions or Bill of Materials takeoffs to our servers or any third-party marketing databases. When you close or refresh your browser tab, your calculation data is cleared.

2. Information We Collect Automatically (Analytics & Performance)

To maintain server uptime, monitor page rendering speeds, and improve tool usability across mobile devices, we collect limited, non-identifying technical data via Google Analytics 4 (GA4):

• Aggregated Usage Metrics: Pages visited, browser type, operating system, approximate geographic region (country and metropolitan area level), referring URLs, and session duration.
• IP Anonymization: IP addresses are automatically truncated and anonymized by GA4 before storage, preventing the personal identification of individual visitors.
• Privacy-Preserving Telemetry: Performance measurements focus strictly on Core Web Vitals (LCP, CLS, FID) to ensure smooth calculation responsiveness.

3. Third-Party Advertising & Google AdSense

To support the ongoing maintenance and free availability of Shiplap Calculator, we work with third-party advertising partners, including Google AdSense, to display relevant advertisements across our website. In accordance with Google's advertising policies, please note:

• Third-Party Vendor Cookies: Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to Shiplap Calculator or other websites across the internet.
• Advertising Cookies: Google's use of advertising cookies enables it and its partners to serve advertisements to you based on your visit to our site and/or other sites on the internet.
• Personalized Advertising Opt-Out: You may opt out of personalized advertising at any time by visiting Google My Ad Center (Ads Settings).
• Industry-Wide Opt-Out Tools: Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the Digital Advertising Alliance Consumer Choice Tool (aboutads.info), the Network Advertising Initiative (NAI) Opt-Out, or for European visitors, Your Online Choices.

4. Cookies, Consent Controls & Local Storage

Our website respects user privacy choices and operates in compliance with international privacy directives (including the EU General Data Protection Regulation (GDPR) and the ePrivacy Directive):

• Consent-Gated Cookies: Cookies are loaded under Google Consent Mode v2 with advertising and analytics storage states defaulted to denied prior to user consent. They are only enabled if you explicitly grant consent through our cookie consent banner.
• European Economic Area (EEA), UK & Switzerland Consent: For visitors in the EEA, UK, and Switzerland, advertising and measurement cookies are served in alignment with a Google-certified Consent Management Platform (CMP) integrating the IAB Transparency and Consent Framework (TCF v2.2).
• Revoking Consent & Cookie Preferences: You can modify or revoke your consent preferences at any time by clearing your browser cookies or clicking the consent controls in the footer.
• Unit Preference Local Storage: Stores your active measurement toggle (Imperial vs. Metric) locally on your device so you do not have to re-select units on returning visits.
• Performance Caching: First-party session tokens used by Vercel edge networks to balance server load and maintain high-speed caching.

You can disable or clear cookies at any time through your web browser preferences without affecting the functionality of our calculators.
