Construction Calculators

Privacy Policy

This document is provided as a template baseline. For legal certainty specific to your jurisdiction, consult a qualified lawyer. Last updated: August 2026.

[BUSINESS_NAME] ("we," "us," or "our") operates [SITE_NAME], a set of free construction calculators for decking, retaining walls, and paint coverage. This Privacy Policy explains what information we collect when you use the site, why we collect it, the legal basis we rely on, and the rights you have over your data. It applies to all visitors, regardless of region, though some sections below describe rights specific to the EEA, UK, California, Australia, and Canada.

We built this site to work without requiring an account, a signup, or an email address, so the amount of personal information we handle is intentionally limited. Where we do collect data — through cookies, analytics, or advertising — we only do so with your consent, which you can grant, withhold, or withdraw at any time through the . Our Cookie Policy describes each cookie category in detail and works alongside this policy.

1. Information we collect

Information you provide directly

The calculators on this site are designed to be used without an account. If you contact us by email, we collect whatever information you include in that message — typically your email address and the content of your inquiry — solely to respond to you.

Information collected automatically

When you visit the site, our hosting provider and, where you consent to Analytics cookies, Google Analytics 4 may automatically log standard technical data such as your IP address (truncated or anonymized where the tool supports it), browser type and version, device type, operating system, referring page, pages visited, time spent on each page, and approximate location derived from your IP address. This data is aggregated for traffic analysis and is not used to build an individual profile of you. Basic server access logs — request timestamps, the page requested, and response status — are generated automatically by our hosting infrastructure regardless of your cookie choices, since these are strictly necessary to operate and secure the site; they are not cross-referenced with analytics or advertising data.

Information from cookies and similar technologies

We use essential cookies to remember your selected region and your cookie consent choices. With your consent, we also use cookies for analytics, advertising, and affiliate attribution. See our Cookie Policy for the full list of cookies, their purpose, and retention period.

Calculator inputs

Measurements and project details you enter into a calculator (such as deck dimensions, wall height, or paint surface area) are processed entirely in your browser to produce your estimate. We do not transmit or store these inputs on our servers, and we have no way to associate them with you or any other visitor.

Region selection

The site asks which region you're in (US, UK, Australia, or Canada) so it can show region-appropriate units, retailer pricing, and permit guidance. This selection is stored in an essential cookie and is not linked to any other identifying information. Region detection based on IP address, where used to suggest a default, is discarded immediately after the suggestion is shown and is never logged or retained.

2. How we use your information

We use the information described above to:

  • Operate and maintain the site, including remembering your region and consent choices between visits;
  • Understand how visitors use the site, so we can improve calculator accuracy and page content (Analytics cookies only, opt-in);
  • Show relevant advertising and measure its performance (Advertising cookies only, opt-in);
  • Attribute purchases made through Amazon Associates links back to this site (Affiliate tracking cookies only, opt-in);
  • Respond to inquiries sent to [BUSINESS_EMAIL]; and
  • Detect, investigate, and prevent abuse, fraud, or security incidents affecting the site.

We do not sell your personal information to third parties, and we do not use your data to make automated decisions that produce legal or similarly significant effects on you. We also do not combine data collected through this site with data from other sources to build an advertising profile beyond what Google Analytics or Google AdSense do independently under their own consent-based products.

3. Legal basis for processing (GDPR / UK GDPR)

If you are located in the EEA or UK, we rely on the following legal bases under the GDPR and UK GDPR to process your information:

  • Consent — for Analytics, Advertising, and Affiliate tracking cookies, and any related processing. You may withdraw consent at any time via the preferences dialog, without affecting the lawfulness of processing carried out before withdrawal.
  • Legitimate interests — for essential cookies that keep the site functioning (region memory, consent memory) and for basic server logs used to maintain security, where these interests are not overridden by your rights.
  • Legal obligation — where we are required to retain or disclose information to comply with applicable law.

4. Sharing and disclosure

We do not sell or rent your personal information. We share limited data with the following categories of third parties, only where the relevant cookie category has been enabled:

  • Google Analytics 4 — aggregated usage data, if you consent to Analytics cookies. Google's own privacy practices govern its handling of this data.
  • Google AdSense — ad delivery and measurement data, if you consent to Advertising cookies.
  • Amazon Associates — click-through and attribution identifiers, if you consent to Affiliate tracking cookies, so that qualifying purchases can be attributed to this site.
  • Hosting and infrastructure providers — who process data on our behalf solely to keep the site running, under their own data processing agreements with us.
  • Legal and safety — where disclosure is required to comply with a legal obligation such as a court order or valid law enforcement request, enforce our Terms of Service, or protect the rights, property, or safety of [BUSINESS_NAME], our users, or the public.
  • Business transfers — if [BUSINESS_NAME] is involved in a merger, acquisition, or sale of assets, information we hold may be transferred as part of that transaction. We will provide notice on the site before your information becomes subject to a materially different privacy policy.

None of the third parties listed above are permitted to use the data we share with them for their own independent marketing purposes beyond what their own privacy policy and consent flow disclose to you directly.

5. Data retention

Essential cookies (region and consent records) persist for up to one year or until you clear your browser storage. Analytics data is retained by Google Analytics for up to 26 months from collection, after which it is automatically deleted. Advertising and affiliate tracking identifiers are retained according to each provider's own policy, generally on a session or short-term basis. Emails you send us are kept only as long as needed to resolve your inquiry, unless we are required to retain them longer for legal reasons.

Server access logs maintained by our hosting provider for security and abuse-prevention purposes are typically retained for a matter of weeks before being automatically overwritten. We do not maintain a separate, long-term log of individual visitor activity.

We take reasonable technical and organizational measures to protect the information described in this policy, including serving the site exclusively over HTTPS, restricting access to hosting and analytics accounts to authorized personnel, and relying on established third-party providers — Google and Amazon — who maintain their own security programs for the data they process on our behalf. No method of transmission or storage is completely secure, and we cannot guarantee absolute security. If we become aware of a breach affecting your personal information, we will notify affected users and relevant authorities as required by applicable law.

6. Your rights

Depending on where you live, you may have some or all of the rights described below. To exercise any of them, contact us at [BUSINESS_EMAIL] with enough detail for us to locate your request in context — for example, the approximate date you visited the site and which cookie categories you had enabled, since we do not maintain account records to look you up by name. We will respond within the timeframe required by the applicable law in your region (for example, one month under the GDPR, extendable in complex cases), and there is no charge for making a request unless it is manifestly unfounded, excessive, or repetitive.

EEA and UK residents (GDPR / UK GDPR)

You have the right to access, correct, or delete your personal data; to restrict or object to our processing of it; to receive a copy of it in a portable format; and to withdraw consent at any time via the . You also have the right to lodge a complaint with your local data protection authority, or the authority in [JURISDICTION] if you believe your rights have been infringed.

California residents (CCPA / CPRA)

You have the right to know what personal information we collect and how it is used and shared, to request deletion of your personal information, to correct inaccurate information, and to opt out of the "sale" or "sharing" of personal information (as those terms are defined under the CCPA) via the link in the site footer. We will not discriminate against you for exercising any of these rights.

Australian residents (Privacy Act 1988)

You have the right to access the personal information we hold about you and to request correction of any information that is inaccurate, out of date, or incomplete. You may also make a complaint about our handling of your personal information, and if unresolved, escalate it to the Office of the Australian Information Commissioner (OAIC).

Canadian residents (PIPEDA)

You have the right to access the personal information we hold about you, to challenge its accuracy, and to have it amended where appropriate. You may also file a complaint with the Office of the Privacy Commissioner of Canada if you believe we have not handled your information in accordance with PIPEDA.

7. International data transfers

[BUSINESS_NAME] is based in [JURISDICTION], and our service providers — including our hosting infrastructure, Google Analytics, Google AdSense, and Amazon Associates — may process data in the United States or other countries outside your own. Where we transfer personal information out of the EEA or UK, we rely on the providers' Standard Contractual Clauses or another legally recognized transfer mechanism to ensure your data receives a level of protection equivalent to what it would receive in your home jurisdiction.

If you would like more detail on the specific safeguards applicable to a given transfer, contact us at [BUSINESS_EMAIL] and we will provide the relevant information on request, consistent with our obligations under the GDPR and UK GDPR.

8. Children's privacy

This site is not directed at children, and we do not knowingly collect personal information from anyone under the age of 16. The calculators themselves require no personal information to use, but if you believe a child has provided us with personal information — for example, by emailing us directly — contact us at [BUSINESS_EMAIL] and we will delete it promptly.

9. Changes to this policy

We may update this Privacy Policy from time to time to reflect changes in our practices or applicable law. Material changes will be announced via a notice on the site. This policy is effective as of [LAST_UPDATED_DATE], and continued use of the site after that date constitutes acceptance of the revised policy.

10. Contact us

Questions, requests, or complaints about this Privacy Policy or our handling of your personal information can be sent to [BUSINESS_EMAIL], or by mail to [BUSINESS_ADDRESS].
