Privacy Policy
CalcSummit does not store your calculator inputs. When you use our construction calculators, your numbers stay in your browser — we never receive them. We collect anonymous usage data via Google Analytics and the email address you provide only if you contact us. This policy explains exactly what we collect and how we use it.
1. What Does CalcSummit Collect?
CalcSummit is designed for minimal data collection. When we refer to personal information (also called personal data under GDPR), we mean any information that identifies or could identify you as an individual. Three categories apply to CalcSummit.
Calculator Inputs — Not Collected
Every CalcSummit calculator runs entirely in your browser using client-side JavaScript. The dimensions, quantities, and values you enter are never transmitted to CalcSummit servers. We have no record of what you calculated, when, or for which project.
Usage Data — Anonymous Analytics
When you visit CalcSummit, Google Analytics 4 (GA4) automatically collects anonymized technical data: approximate geographic region (city-level, not address), browser type, device category, pages visited, and session duration. IP addresses are anonymized before storage. This data is used in aggregate only — it never identifies individual users.
Contact Information — Only If You Contact Us
If you use our contact form or email us directly, we collect your name and email address to respond to your inquiry. We do not add you to marketing lists. Contact data is stored only as long as needed to resolve your inquiry.
2. How We Use Your Information
CalcSummit uses the limited data we collect for four purposes only:
- Operate and improve construction calculators and site performance
- Understand which calculators are most useful to contractors and estimators
- Diagnose technical errors and resolve accuracy reports
- Serve non-intrusive display advertisements that fund free calculator access
We do not sell, rent, or share your personal information with third parties for their marketing purposes.
4. Third-Party Services
CalcSummit uses these third-party services. Each has its own privacy policy, which we link below.
- Google Analytics 4 — Anonymous usage statistics. Google Privacy Policy.
- Cloudflare — CDN, DDoS protection, and performance. Cloudflare Privacy Policy.
- Display ad networks — Non-intrusive advertising. opt out at aboutads.info.
5. Your Rights Under GDPR (EU and UK Visitors)
If you are located in the European Union or the United Kingdom, the General Data Protection Regulation (GDPR) gives you the following rights regarding your personal data:
- Right to access — request a copy of data we hold about you
- Right to rectification — request correction of inaccurate data
- Right to erasure — request deletion of your data
- Right to restrict processing — limit how we use your data
- Right to data portability — receive your data in a machine-readable format
- Right to object — object to processing based on legitimate interests
How to Make a GDPR Request
Email privacy@calcsummit.com with your request type (access, deletion, correction, etc.) and any relevant details. Because CalcSummit collects no personally identifiable information in normal use, the most common response is confirmation that no personal data exists.
Response Timeline
CalcSummit responds to all GDPR requests within 30 days. If your request is complex or numerous, we may extend this period by 2 additional months and will notify you within 30 days with the reason.
6. Your Rights Under CCPA (California Residents)
Under the California Consumer Privacy Act (CCPA) and its 2026 amendments, California residents have the right to:
- Know what personal information CalcSummit collects about you
- Know whether CalcSummit sells or discloses your personal information
- Opt out of the sale of your personal information (CalcSummit does not sell data)
- Request deletion of your personal information
- Not be discriminated against for exercising your CCPA rights
- Opt out of automated decision-making (2026 amendment)
How to Exercise Your CCPA Rights
Submit requests to privacy@calcsummit.com or via our contact form. Select “GDPR/CCPA Data Request” from the inquiry type dropdown.
2026 CCPA Updates
The 2026 CCPA amendments expand consumer rights to include disclosures about automated decision-making and extend data look-back periods beyond 12 months for categories of sensitive data. CalcSummit does not engage in automated decision-making that affects consumers and does not hold sensitive data categories.
Applicable laws: California Consumer Privacy Act (CCPA, Cal. Civ. Code §1798.100) · California Privacy Rights Act (CPRA, Proposition 24, 2020) · California Online Privacy Protection Act (CalOPPA, Cal. Bus. & Prof. Code §22575) · GDPR (EU Regulation 2016/679) · COPPA (15 U.S.C. §6501). Questions about CalcSummit’s legal structure and data controller status can be directed to our About page.
7. Data Retention
Retention periods by data type:
- Calculator inputs — never collected; no retention period applies
- Anonymous analytics data (GA4) — 26 months per Google Analytics default settings
- Contact inquiry data (name and email) — deleted after inquiry resolution, no longer than 12 months
8. How We Protect Your Information
CalcSummit serves all pages over HTTPS (TLS 1.3). The site is delivered via Cloudflare's CDN, which provides DDoS protection, firewall filtering, and automatic HTTPS enforcement. Because CalcSummit collects no personally identifiable information in normal use, the primary security benefit is preventing interception of your session — not protecting a personal data store that does not exist.
9. Children's Privacy
CalcSummit is not directed at children under 13. We do not knowingly collect personal information from children. If you believe we have inadvertently received information from a child under 13, contact us immediately at privacy@calcsummit.com and we will delete it promptly.
10. Changes to This Privacy Policy
CalcSummit reviews this Privacy Policy annually and updates it whenever new data practices are adopted, new third-party services are added, or regulations change. Material changes are reflected in the “Last updated” date at the top of this page. Continued use of CalcSummit after a policy update constitutes acceptance of the revised terms.
