Privacy Policy

Effective Date: February 27, 2026
Last Updated: February 27, 2026

This Privacy Policy describes how justcalendar.ai ("Just Calendar", "we", "our", "us") collects, uses, and protects information when you use https://justcalendar.ai.

By using the website, you agree to this Privacy Policy.

1. Information We Process

A) Information stored in your browser (local-only app data)

Just Calendar stores your calendar app data in your own browser via localStorage so the app can remember your content and preferences. This can include:

• Calendar definitions (names, types, colors, pinned state)
• Day values and notes entered in the calendar
• Theme and UI tuning preferences

This localStorage data remains on your device/browser unless you clear it.

B) Google Drive connection data (optional feature)

If you choose Login to Google Drive, we process OAuth tokens to connect your account:

• Requested scope: https://www.googleapis.com/auth/drive.file
• We do not request Google Sign-In, email, or profile scopes for this connection
• Refresh/access tokens are stored server-side (not in browser localStorage)

Tokens are used only to maintain the Google Drive connection and request valid access tokens when needed.

C) Analytics and technical usage data

The site uses Google Analytics (Measurement ID: G-NWX6ELVVTS), which may collect data such as:

• Device/browser details
• Page views and interaction events
• IP-based and referral-related analytics information

Google may use cookies or similar technologies for analytics.

D) Basic technical logs

As with most websites, hosting/network infrastructure may process standard technical request data (for example IP address, user agent, request times) for reliability and security.

2. How We Use Information

We use information to:

• Provide and operate the calendar application
• Persist your settings and calendar state
• Support optional Google Drive authentication/connection
• Monitor performance and improve the website
• Protect service security and integrity
• Comply with legal obligations

3. How We Share Information

We do not sell your personal information.

Information may be shared with:

• Service providers required to operate the website (for example hosting and analytics)
• Google, when you explicitly choose to connect Google Drive
• Authorities/law enforcement where legally required

4. Cookies and Similar Technologies

We and our service providers may use cookies or similar technologies for:

• Analytics
• Security/session management for OAuth flows

You can control cookies through your browser settings. Some functionality may be affected.

5. Data Retention

• Browser localStorage data is kept until you clear browser storage.
• OAuth tokens are retained server-side until you disconnect Google Drive or tokens are revoked/invalidated.
• Analytics and infrastructure logs are retained according to provider/system policies.

6. Security

We use reasonable technical and organizational measures to protect data. No method of storage or transmission is completely secure, so absolute security cannot be guaranteed.

7. Your Choices

You can:

• Clear localStorage in your browser to remove locally stored app data
• Disconnect Google Drive from the app
• Revoke app access in your Google account permissions
• Limit cookies/analytics via browser settings and available browser privacy controls

8. Children's Privacy

This website is not directed to children under 13, and we do not knowingly collect personal information from children under 13.

9. International Users

Depending on where you access the service, your information may be processed in countries outside your jurisdiction.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Updates will be posted on this page with an updated Last Updated date.
