Privacy Policy

Last updated: August 8, 2026

This Privacy Policy explains how 123calendar.online ("we", "us", "our") handles information when you visit our website and use our calendars, planners and templates.

1. Your calendar notes stay on your device

Anything you type into a calendar, planner or template — appointments, names, reminders, notes — is stored exclusively in your own browser using local storage. This data is never transmitted to our servers, never backed up by us, and never visible to us or to anyone else. Clearing your browser data deletes it permanently.

2. Information we collect

We do not operate user accounts and we do not ask you for your name, email address or any other personal information in order to use the site. Like most websites, we and our service providers may automatically receive standard, non-identifying technical information such as browser type, device type, operating system, referring page, pages viewed and approximate country-level location.

3. Cookies and advertising

We display third-party advertising, including Google AdSense, to keep this site free to use. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.

• You may opt out of personalized advertising by visiting Google Ads Settings.
• You can opt out of third-party vendor cookies at www.aboutads.info.
• Third-party vendors and ad networks may also place cookies independently of us; their use of those cookies is governed by their own privacy policies.

4. Analytics

We may use privacy-respecting analytics to understand aggregate usage — which calendars are most popular and whether pages load correctly. This information is anonymous and cannot be used to identify individual visitors.

5. Children's privacy

Our services are not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can remove it.

6. Your rights

Because we do not collect or store personal data about you, there is generally nothing for us to access, correct or delete on request. To remove the calendar notes stored on your device, clear your browser's site data for 123calendar.online, or use the "Clear" button on any calendar page.

7. Third-party links

Our pages may link to external websites. We are not responsible for the content or privacy practices of other sites and encourage you to review their policies.

8. Changes to this policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page along with a revised "last updated" date.
