Privacy Policy

1. Information We Collect

CALULU (the “Service”) collects the following information for the purpose of scheduling.

• Account information: The name, email address, and profile image of your Google/Microsoft account
• Calendar information: Collected according to the read scope you select when connecting. In “Free/busy only” mode, we collect only the start/end times of events (free or busy) and never collect event titles, details, or attendees. Even in “Include titles” mode, event details are never shown to other participants.

2. Purpose of Use

The information collected is used solely to calculate common free time across multiple participants, propose candidate dates and times, add confirmed events to your calendar, and send reminder notifications. We do not use it for advertising purposes or provide it to third parties without your consent.

3. Storage and Protection

Data is stored on Google Cloud (Firestore). The OAuth tokens used to access your calendar are encrypted with AES-256-GCM before storage. We do not store the calendar event data itself; it is fetched from the API each time candidates are calculated.

4. Limited Use of Google APIs

CALULU's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

5. Data Deletion

You can disconnect calendar integration at any time from the settings screen, and saved tokens are deleted when you do. If you would like all data associated with your account deleted, please contact us at the address below. You can also revoke this Service's access from your Google Account settings.
