Privacy Policy

Effective / last updated: 2026-06-25

1. Information we collect and do not collect

Anniversary Calculator has no sign-up process and does not request or collect information that directly identifies you, such as your name or contact details. The dates you enter into the calculators (start date, anniversary, wedding date, etc.) are used only within your browser, disappear automatically, and are never sent to or stored on our server.

However, the following information may be generated and collected automatically as you use the website.

• Access IP address, browser type and version, operating system, and visit time
• Pages visited, referring page, and device information
• Anonymous identifiers via cookies and similar technologies

2. Use of cookies

Anniversary Calculator 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 your visits and settings.

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

3. Google AdSense and third-party advertising

Anniversary Calculator displays ads through Google AdSense. Third-party advertising 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 based on your visits to this and other sites.
• You can opt out of personalized advertising at Google Ads Settings.
• You can review and opt out of third-party advertising vendors' use of cookies at www.aboutads.info.
• You can learn how Google handles data on the How Google uses data from partner sites page.

4. Analytics tools

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

5. Data retention and third-party provision

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

6. Your rights

You have the right to refuse data collection through your browser cookie settings, and you can disable personalized ads in Google Ads Settings. For inquiries about data handling, contact us at the address below.

7. Children's privacy

Anniversary Calculator is not primarily directed at children under 14 and does not knowingly collect children's personal data.

8. Changes to this policy

This privacy policy may be amended in line with legal or service changes, and any changes will be announced on this page. For significant changes, we will update the effective date.
