This Privacy Policy explains how Gutter Slope Calculator ("we", "our", or "us"), operated at https://gutterslopecalculator.com, collects, uses, and protects information when you use our free online gutter slope and fall calculation tools. We are committed to protecting your privacy and being transparent about our practices.
By using Gutter Slope Calculator, you agree to the practices described in this policy. If you do not agree, please discontinue use of the site.
1. What Gutter Slope Calculator Does
Gutter Slope Calculator is a free, browser-based engineering tool that helps homeowners and professionals calculate gutter slope (pitch), required drop, maximum run length, fall rates, and related drainage figures. Our tools include:
- Gutter slope and fall calculators (US, UK, Australia, New Zealand)
- Box gutter fall, seamless gutter slope, and roof gutter fall calculators
- Gutter pitch, angle, flow, and spread calculators
- Interactive SVG diagrams and reference tables
All calculations are performed entirely within your browser. No calculation inputs or results are ever transmitted to our servers.
2. Information We Collect
2.1 Information You Enter Into the Calculators
The values you type into our calculators — such as run length, drop, pitch, fall rate, and unit preferences — are processed locally in your browser using JavaScript. This data is not sent to us or any third party. It exists only in your current browser session and optionally in your browser's local storage (see Section 4).
2.2 Contact Form Submissions
If you contact us via our contact form, we collect the name, email address, and message content you provide. This information is used solely to respond to your enquiry and is not added to any marketing list or shared with third parties beyond the form delivery service we use to receive your message.
2.3 Usage and Analytics Data
We may collect anonymized, aggregate data about how visitors use the site — for example, which calculator pages are visited most frequently, approximate geographic region (country level), browser type, and device type. This data helps us improve and prioritize the tools. We do not use this data to identify individual users.
2.4 Automatically Collected Technical Data
Like most websites, our hosting infrastructure may automatically record standard server log data including your IP address, the pages you visit, and the date and time of your visit. This information is used for security, uptime monitoring, and debugging purposes and is not linked to your identity.
3. How We Use Information
We use the information we collect to:
- Operate, maintain, and improve Gutter Slope Calculator and its tools
- Respond to enquiries you send via our contact form
- Monitor site security and diagnose technical problems
- Understand aggregate usage patterns to prioritize new features (e.g., which regional calculators are most used)
- Comply with applicable legal obligations
We do not sell, rent, or share your personal information with third parties for their marketing purposes.
4. Browser Local Storage
To make the tools more convenient across visits, your most recent calculator inputs — such as the last run length, unit preference, or pitch preset you selected — may be saved in your browser's local storage. Local storage is a standard browser feature that stores small amounts of data on your own device.
Key facts about local storage on this site:
- It never leaves your device. Nothing stored in local storage is transmitted to us or any server.
- You can clear it at any time by clicking the Reset button within a calculator, or by clearing your browser's site data in your browser settings.
- It is not a cookie. Local storage data is not sent with HTTP requests and is not accessible by any other website.
5. Cookies
Gutter Slope Calculator may use a small number of cookies for the following purposes:
- Analytics cookies — if we use a third-party analytics service (such as Google Analytics or a privacy-first alternative), a cookie may be set to distinguish unique visits for aggregate reporting. We configure analytics to anonymize IP addresses and disable advertising features.
- Preference cookies — to remember your preferred unit system (imperial/metric) or language across sessions.
We do not use cookies for advertising, retargeting, or tracking across other websites. We do not use third-party advertising cookies.
You can control or delete cookies through your browser settings at any time. Disabling cookies may affect minor convenience features (e.g., saved unit preferences) but will not prevent the calculators from working.
6. Third-Party Services
We use a limited set of third-party services to operate the site:
- Hosting & CDN — our site is hosted on a cloud infrastructure provider. Server logs may be retained by the provider per their standard data-retention policies.
- Analytics — we may use an analytics service to collect aggregate, anonymized usage statistics. No personal profiles are built, and data is not used for advertising.
- Contact form — form submissions are delivered via a third-party form service. The service receives your name, email, and message to forward to us. Their own privacy policy applies to how they handle this data in transit.
- Google Fonts — the site loads typefaces (Cormorant Garamond, Inter) from Google Fonts. Google may log font requests; see Google's Privacy Policy for details. No personal data from our site is shared with Google Fonts.
We do not use Facebook Pixel, Google Ads, or any other advertising tracking technology.
7. Data Retention
We retain different types of data for different periods:
- Calculator inputs — never collected by us; exist only in your browser session or local storage under your control.
- Contact form messages — retained as long as necessary to resolve your enquiry, typically no longer than 12 months.
- Server logs — retained by our hosting provider in line with their standard policy (usually 30–90 days), for security and diagnostic purposes.
- Analytics data — retained in aggregate, anonymized form for up to 26 months to identify long-term usage trends.
8. Your Rights
Depending on where you are located, you may have rights under applicable privacy laws, including:
- Access — the right to request a copy of personal information we hold about you.
- Correction — the right to request correction of inaccurate personal data.
- Deletion — the right to request deletion of personal data we hold (subject to legal retention obligations).
- Objection / restriction — the right to object to or restrict certain processing activities.
- Data portability — the right to receive your data in a structured, machine-readable format where technically feasible.
- Withdraw consent — where processing is based on consent (e.g., analytics cookies), you may withdraw consent at any time without affecting the lawfulness of prior processing.
Because we collect very little personal data, most rights requests will be straightforward to fulfill. To exercise any of these rights, contact us at contact@gutterslopecalculator.com. We aim to respond within 30 days.
9. Children's Privacy
Gutter Slope Calculator is a professional and DIY construction planning tool not directed at children under 13 years of age (or under 16 in the European Economic Area). We do not knowingly collect personal information from children. If you believe a child has submitted personal information to us, please contact us and we will delete it promptly.
10. Security
We take reasonable technical and organizational measures to protect the limited personal data we do handle, including encrypted HTTPS transmission for all pages, access controls on server infrastructure, and minimizing data collection at the point of design. No Internet transmission is 100% secure, but we are committed to protecting your information against unauthorized access.
11. International Visitors
Gutter Slope Calculator is used by visitors in many countries, including the United States, United Kingdom, Australia, and New Zealand. If you are accessing the site from outside the country where our servers are located, your information may be transferred internationally. By using the site, you consent to such transfers to the extent they involve limited data (server logs, analytics).
If you are in the European Economic Area (EEA), United Kingdom, or Switzerland, we rely on our legitimate interests (operating and improving a free public tool) as the legal basis for the minimal data processing we perform, and on consent for analytics cookies where required.
12. Third-Party Links
Some pages on our site contain links to external resources — for example, links to AS/NZS standards information, manufacturer guidance, or related tools. Once you leave https://gutterslopecalculator.com, this Privacy Policy no longer applies. We encourage you to read the privacy policies of any external sites you visit.
13. Changes to This Policy
We may revise this Privacy Policy from time to time as the site grows or as legal requirements change. The "Last updated" date at the top of this page will reflect the most recent revision. If we make material changes, we will update the date prominently. Your continued use of the site after a change constitutes acceptance of the updated policy.
