This Privacy Policy explains how CalculatorMom (“we,” “our,” or “us”), available at calculatormom.com, collects, uses, and protects information when you visit our website. Please read this policy carefully. By using CalculatorMom, you agree to the practices described here.
We are committed to being transparent about our data practices. CalculatorMom is a free calculator site — not a data business. We collect the minimum information needed to operate and improve the site, and we do not sell personal data to anyone.
What CalculatorMom Is
CalculatorMom provides free, browser-based calculators covering vehicle costs, household budgets, fitness and body metrics, and YouTube creator tools. Every calculator on this site runs entirely within your browser. The numbers you enter into any calculator are processed locally on your device and are never sent to our servers, stored in a database, or linked to your identity in any way.
We do not require you to create an account, provide your name, or submit an email address to use any tool on this site. The site is fully accessible without registration of any kind.
Information We Collect Automatically
When you visit CalculatorMom, certain technical information is collected automatically by our hosting infrastructure and analytics tools. This information does not identify you personally and is used only to understand how the site is used and to keep it running reliably.
Automatically collected information includes:
- Your IP address (used to determine approximate geographic region — country or city level — and then stored in anonymised or aggregated form)
- Browser type and version (for example, Chrome 124, Safari 17)
- Operating system and device type (desktop, tablet, or mobile)
- The pages you visit on CalculatorMom and how long you spend on each
- The URL of the page or search engine that referred you to our site
- Date and time of your visit
- HTTP status codes and response sizes (used for technical diagnostics)
- Screen resolution and language settings
None of this information is combined with your name, email, or any other identifier that would allow us to identify you as an individual.
Calculator Inputs
The values you type into any calculator on CalculatorMom — such as loan amounts, income figures, body weight, or vehicle mileage — are processed entirely within your browser using JavaScript. These inputs are:
- Never transmitted to our servers
- Never stored in a database
- Never linked to your IP address or identity
- Cleared when you close or refresh the page
We have no access to what you enter into any calculator on this site.
Log Data
Our hosting provider maintains standard server access logs. These logs record each request made to our web server and include the requesting IP address, the URL requested, the HTTP method, the response code, the size of the response, the referring URL, and the browser user-agent string.
Server logs are used exclusively for:
- Diagnosing technical errors and server issues
- Identifying and blocking abusive or malicious traffic
- Monitoring server performance and uptime
Log data is retained for a limited period, typically 30 to 90 days, and is then deleted or anonymised. Raw log files are not shared with third parties except where required by law or necessary to investigate a security incident.
Cookies
A cookie is a small text file that a website stores in your browser. Cookies allow websites to remember preferences, measure traffic, and in some cases deliver advertising. CalculatorMom uses cookies for analytics purposes, as described below.
Analytics Cookies
We use Google Analytics to understand how visitors interact with our site — which calculators are used most often, how long visitors stay, which pages they arrive from, and which devices they use. This data is aggregated and does not identify individual users.
Google Analytics sets the following cookies:
- _ga — Distinguishes unique users. Expires after 2 years.
- _gid — Distinguishes unique users. Expires after 24 hours.
- _gat — Used to throttle request rate. Expires after 1 minute.
We have enabled IP anonymisation in Google Analytics, meaning your full IP address is never stored by Google in connection with our analytics data.
You can opt out of Google Analytics tracking across all websites by installing the official Google Analytics opt-out browser add-on.
Advertising Cookies
CalculatorMom does not currently serve advertising. If the site begins displaying advertisements in future, those ad networks may set their own cookies to personalise ad delivery. This policy will be updated to reflect any such change before it takes effect, and full details of any advertising cookies will be disclosed at that time.
Essential Cookies
Some cookies are necessary for the basic operation of the website, such as session management and security. These cookies do not collect personal information and cannot be disabled without affecting site functionality.
Managing Cookies in Your Browser
You can control or delete cookies through your browser settings at any time. Note that disabling certain cookies may affect how the site functions or how analytics data is recorded.
- Google Chrome — manage cookies
- Mozilla Firefox — manage cookies
- Apple Safari — manage cookies
- Microsoft Edge — manage cookies
Advertising
CalculatorMom is currently a free, ad-free website. We may in future display advertisements through third-party advertising networks in order to fund the ongoing development and maintenance of the site and keep all calculators free to use.
If and when advertising is enabled:
- We will update this Privacy Policy before activating any ad network
- Any advertising network used may set its own cookies and collect data about your browsing behaviour to serve relevant ads
- We will always label advertisements clearly so you can distinguish them from our calculator content
- No advertiser will have any influence over our calculator formulas, results, or editorial content
- We will not accept payment from specific brands to promote their products within our calculator tools or editorial pages
You can manage interest-based advertising preferences now through these industry opt-out tools, which will apply when advertising is active:
- Google Ad Settings — control how Google uses your data to show you ads
- Network Advertising Initiative opt-out tool — opt out from multiple ad networks at once
- Digital Advertising Alliance opt-out tool — for US visitors
- Your Online Choices — for EU/UK visitors
Opting out of personalised advertising does not prevent ads from appearing — it means ads will not be tailored to your browsing history or interests.
7. How We Use Information
The information we collect automatically is used for the following purposes only:
- Site operation — ensuring the website loads correctly, calculators function as expected, and pages are delivered reliably
- Performance monitoring — identifying slow-loading pages, broken links, or calculator errors
- Analytics — understanding which calculators are most useful, how visitors find the site, and where improvements are needed
- Security — detecting and blocking malicious traffic, bots, or abuse

We do not use collected data for:

Data Sharing and Disclosure
We do not sell, rent, or trade personal information. We share data only in the following limited circumstances:
Service providers — We use third-party services to operate the site, including hosting providers and analytics tools (Google Analytics). These providers process data on our behalf and are bound by their own privacy policies and data processing agreements. They are not permitted to use your data for their own purposes beyond providing the service.
Legal requirements — We may disclose information if required to do so by law, court order, or government authority, or where we believe disclosure is necessary to protect our legal rights, prevent fraud, or protect the safety of users.
Business transfers — In the unlikely event that CalculatorMom is sold or transferred to another operator, user data would transfer as part of that transaction. You would be notified of any such change through an update to this Privacy Policy.
In all other cases, your data is not shared with any third party.
Data Retention
We retain automatically collected data only as long as necessary for the purposes described in this policy:
- Server logs — retained for 30 to 90 days, then deleted or anonymised
- Google Analytics data — retained for 14 months by default, after which it is automatically deleted from Google’s systems (per our Analytics settings)
- Contact form submissions — if you contact us, we retain your message and email address for as long as needed to resolve your enquiry, and no longer
You may request deletion of any data we hold about you by contacting us using the details at the bottom of this page.
Third-Party Services
CalculatorMom uses the following third-party services, each governed by its own privacy policy:
- Google Analytics (Google LLC) — website usage analytics. Google Privacy Policy
- WordPress (Automattic Inc.) — content management system. Automattic Privacy Policy
- WPForms — contact form processing. Data submitted through contact forms is stored within our WordPress installation.
We do not use social media share buttons, tracking pixels from social platforms, or any affiliate tracking scripts on this site.
Security
We take reasonable technical and organisational precautions to protect the information collected through this website. These measures include:
- HTTPS encryption on all pages to protect data in transit
- Regular software updates and security patches for our hosting environment and WordPress installation
- Limited access to server infrastructure and analytics data

No method of transmission over the internet is completely secure. While we take data security seriously, we cannot guarantee absolute security. If you believe your data has been compromised in connection with our site, please contact us immediately.
Children’s Privacy
CalculatorMom is a general-audience website and is not directed at or intended for children under the age of 13. We do not knowingly collect personal information from children. Our calculators cover topics — vehicle costs, financial planning, fitness metrics — that are primarily relevant to adults.
If you are a parent or guardian and believe that a child under 13 has submitted personal information through our contact form, please contact us and we will delete that information promptly.
