Privacy Policy
Effective · Last updated: 2026-06-25
Baby Calculators does not require sign-up, and the values you enter into the calculators — weight, age, height, birth date, and so on — are processed only in your browser and never sent to or stored on a server.
To run the free service, however, we display Google AdSense ads, and cookies and advertising identifiers may be used in that process.
1. Overview
Baby Calculators (the "Site") values your privacy and complies with applicable data protection laws. This policy explains what information the Site processes and how, and how advertising and cookies are used.
2. Information the Site does not collect directly
All calculators on the Site run client-side (in your browser). The values you enter — your baby's weight, age in months, height, weight, birth date, and so on — are used only within your browser for the calculation and are not sent to or stored on the operator's server. The Site does not directly collect personally identifying information such as sign-up, login, names, or contact details.
3. Use of cookies
A cookie is a small text file a website stores in your browser. The Site itself has no login feature and uses almost no essential cookies, but the third-party advertising and analytics services below may use cookies. You can refuse or delete cookie storage in your browser settings; in that case, some ads may appear unrelated to your interests.
4. Google AdSense advertising
The Site displays ads through Google AdSense to keep the service free. The following applies to advertising.
- Third-party ad vendors, including Google, may use cookies to serve personalized ads based on your prior visits.
- Google uses advertising cookies (such as the DoubleClick cookie) to serve ads, which may collect device/browser information, approximate location, and ad interaction data.
- You can disable personalized ads in your Google Ad Settings.
- You can opt out of third-party ad vendor cookies in bulk at aboutads.info or youronlinechoices.eu.
- For details on how Google handles data, see Google's policies and terms.
5. Analytics tools
The Site may use analytics tools such as Google Analytics to improve the service. These tools use cookies to collect anonymous statistics such as pages visited, time on page, device/browser type, and approximate region, and do not directly identify individuals. If an analytics tool is actually applied, its name is stated in this section.
6. Third-party provision and processing
The Site does not collect your personal information directly, so it does not sell or provide it to third parties. However, in the course of using the advertising and analytics services above, information may be processed under the policies of those providers (such as Google), governed by their respective privacy policies.
7. Your rights
- You can refuse cookie storage or delete existing cookies at any time through your browser settings.
- You can turn off interest-based personalized ads in Google Ad Settings.
- You can send questions about this policy or data handling to the contact below.
8. Children's privacy
The Site provides information for caregivers of infants and toddlers, but does not enroll children as members or collect children's personal information directly. The baby information entered (weight, birth date, etc.) is processed only on the caregiver's device and is not stored or transmitted.
9. Changes to this policy
This privacy policy may be revised as laws or the service change, and any change will be posted on this page along with the change details and effective date.
