Privacy Policy

Effective / last updated: 2026-06-25

1. Information we collect and do not collect

PetCalc has no sign-up process and does not request or collect personally identifiable information such as your name or contact details. The values you enter into the calculators — your pet's age, weight, amount eaten, and so on — are used only within your browser, disappear automatically, and are not sent to or stored on the operator's server.

However, the following information may be automatically generated and collected while using the website:

• Access IP address, browser type and version, operating system, and visit date and time
• Pages visited, the previous page (referrer), and device information
• Anonymous identifiers via cookies and similar technologies

2. Use of cookies

PetCalc may use cookies to provide the service and to display ads. A cookie is a small text file that a website stores in your browser to remember visit history and settings.

You can refuse or delete cookies in your web browser settings. However, blocking cookies may limit some features and ad personalization. Cookie settings can be changed in the settings menu of each browser (Chrome, Safari, Edge, and so on).

3. Google AdSense and third-party advertising

PetCalc displays ads through Google AdSense. Third-party ad vendors, including Google, may use cookies to provide personalized ads based on your previous visit history.

• Google uses advertising cookies (such as the DoubleClick cookie) to serve ads based on your visits to this and other sites.
• You can opt out of personalized advertising in Google Ad Settings.
• You can review and opt out of third-party ad vendor cookie use at www.aboutads.info.
• You can review how Google handles data on the How Google uses data from sites that use our services page.

4. Analytics tools

To improve the service, we may use web analytics tools such as Google Analytics. These tools collect anonymized statistics, such as pages visited and time on page, through cookies, and do not identify any specific individual.

5. Data retention and third-party sharing

Because PetCalc does not directly collect or store your personal data, no separate retention period applies. Automatically collected access information and cookie data are processed and stored according to the policies of the relevant service providers, such as Google. Except as required by law, the operator does not sell user information to or arbitrarily provide it to third parties.

6. Your rights

You have the right to refuse data collection through your browser cookie settings and to disable personalized ads in Google Ad Settings. For inquiries related to data processing, you can use the contact below.

7. Children's privacy

PetCalc is not primarily intended for children under the age of 14 and does not knowingly collect children's personal data.

8. Changes to this policy

This privacy policy may be revised in line with laws or service changes, and any change will be announced on this page. For important changes, we will update the effective date.
