1. Who We Are

DayCal ("we", "us", "our") is a personal calendar and task management application available at https://apar-gif.github.io/DayCal. This Privacy Policy explains how we collect, use, and protect your information.

2. Information We Collect

We collect and store the following types of information:

• Account information: Your email address and password (hashed) when you sign up, stored securely via Supabase.
• Calendar data: Events you create directly in DayCal, including titles, dates, times, locations, and recurrence rules.
• Task data: Tasks, groups, time estimates, and scheduling information you enter.
• Google Calendar data: If you choose to sync with Google Calendar, we access and import your Google Calendar events with your explicit permission. See Section 4 for full details.

3. How We Use Your Information

We use the information we collect solely to:

• Display your calendar events and tasks within the app
• Enable AI-powered scheduling suggestions based on your free time slots
• Sync imported Google Calendar events to your personal DayCal storage
• Authenticate your identity and maintain your session

We do not use your data for advertising, sell it to third parties, or share it with anyone except as described in this policy.

4. Google Calendar Integration & Use of Google User Data

DayCal integrates with the Google Calendar API to allow you to import your Google Calendar events. This integration is entirely optional.

What we access: When you click "Sync Google Calendar" and authorize the connection, we request the following OAuth scopes:

• https://www.googleapis.com/auth/calendar.readonly — Read-only access to your Google Calendar events
• https://www.googleapis.com/auth/userinfo.email — Your Google account email address (used to label which Google account the calendars came from)

What we do with it:

• We fetch your calendar list and events within a defined date range (approximately 2 months back to 1 year ahead)
• We store imported events in your personal Supabase database account — not in any shared or central database
• Your Google data is only visible to you when signed in to your DayCal account
• We do not write, modify, or delete any events in your Google Calendar — access is strictly read-only
• We do not share your Google Calendar data with any third parties
• We do not use your Google Calendar data for advertising or analytics
• Your Google OAuth access token is used only during the active sync session and is never stored permanently

Revoking access: You can revoke DayCal's access to your Google Calendar at any time by visiting myaccount.google.com/permissions and removing DayCal from the list of connected apps.

DayCal's use of Google user data complies with the Google API Services User Data Policy, including the Limited Use requirements.

5. Data Storage & Security

Your data is stored using Supabase, a secure cloud database platform. All data is protected by:

• Row-Level Security (RLS) policies — only you can access your own data
• Encrypted connections (HTTPS/TLS) for all data in transit
• Secure authentication via email and password (bcrypt-hashed)

6. Data Retention

Your data is retained as long as your account exists. You may request deletion of your account and all associated data by contacting us at the email below. Imported Google Calendar events can be removed by deleting the associated calendars within the app.

7. Children's Privacy

DayCal is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13.
