Privacy Policy

Effective Date: November 1, 2025

CMU Study (“we,” “our,” or “the app”) uses the Google Calendar API solely to help users create and manage study-related events on their Google Calendar. This Privacy Policy explains what data we access, how we use it, how we store and protect it, and what control users have over their information.

Data Accessed

CMU Study only requests the minimum Google Calendar permissions necessary to function.

Google User Data Accessed

Permission to create new events on your Google Calendar
Permission to delete events previously created by the app

Data We Do Not Access

We do not read, view, or access:

Existing events on your calendar
Event titles, descriptions, times, or locations
Attendee information
Any other personal Google Calendar data

No other Google user data is accessed beyond the limited scope described above.

How We Use Google User Data

We use your granted calendar access solely to:

Create events on your Google Calendar when you request it
Delete events created by CMU Study if you choose to remove them

We do not:

Process, analyze, or scan your events
Use your data for advertising or marketing
Combine calendar data with any other data sources

All event creation and deletion occurs only when you explicitly request it.

Data We Store

We store only one piece of information: the event ID for each event created by CMU Study. This ID allows the app to modify or delete the event later if you choose.

We do not store:

Event titles
Event descriptions
Dates, times, or locations
Attendee lists
Any personal Google Calendar content

Data Sharing

We do not share, sell, or transmit any Google user data or stored event IDs to third parties.

Your data is never shared with:

Advertisers
Analytics providers
External companies or researchers
Any third-party service

CMU Study operates independently and does not integrate with any third-party system that uses your data.

Data Storage & Protection

We use reasonable industry security measures to protect stored event IDs, including:

Secure server storage
Restricted internal access controls
Logical and physical safeguards

Since we do not store any personal calendar content, overall exposure risk is minimal.

Data Retention & Deletion

How Long We Retain Data

Event IDs are retained only as long as needed to allow users to modify or delete events created by the app. They may be removed automatically when no longer necessary.

User Data Deletion

You may request deletion of stored event IDs at any time by contacting:
cmustudy.help@gmail.com

Revoking Access

You can revoke the app's access to your Google Account at any time via your Google Account Permissions page. After access is revoked, the app will no longer be able to create or delete events.

Changes to This Policy

We may update this Privacy Policy from time to time. Any revisions will be posted on this page with a new effective date.
