2. Collecting and Using Your Data

 

2.1. Types of Data Collected

The Extension stores the following data locally on your device using Chrome's

built-in chrome.storage.local API. No data is ever transmitted to our servers

or any third party.

Data stored locally includes:

• Google OAuth access token — obtained via Google Sign-In to authenticate

Calendar API requests on your behalf.

• Cached calendar events — a temporary local copy of your Google Calendar

events, refreshed every 10 minutes to keep the display up to date.

• Calendar visibility preferences — which of your calendars are shown or

hidden in the bar.

• Layout preference — whether you have chosen the horizontal bar or vertical

sidebar mode.

We do not collect or store:

• Your name, email address, or any other personally identifiable information

• Your browsing history or search queries

• Any website content you interact with

• Any login credentials or passwords

 

2.2. Google Calendar Integration

Connecting your Google account is required for the core functionality of

Persistent Calendar Bar. The Extension uses OAuth 2.0 via the Chrome Identity

API to request access to your Google Calendar data. You will be prompted to

authorize the following scopes:

• https://www.googleapis.com/auth/calendar.readonly — to read your calendars

and events.

• https://www.googleapis.com/auth/calendar.events — to allow you to create new

events directly from the Extension.

You can revoke this access at any time through your Google Account settings or

by using the Disconnect button within the Extension, which will remove the

stored token and clear all cached event data from your device.

 

2.3. How Do We Use Your Data?

All data used by the Extension is stored locally on your device and is never

transmitted to us or any third party. The Extension uses this data solely to:

• Display your Google Calendar events in the persistent calendar bar overlay.

• Allow you to navigate between days and time windows.

• Allow you to create new calendar events.

• Remember your display preferences across sessions.

This data is not used for analytics, advertising, profiling, or any purpose

beyond the Extension's core calendar display functionality.

 

3. Sharing Your Data

 

3.1. Retention of Your Data

We do not retain any data. All data is stored locally on your device and is

never transmitted to us. Cached event data is automatically cleared when you

disconnect your Google account from the Extension.

 

3.2. Transfer of Your Data

As we do not collect or store your data on our servers, there is no transfer

of your personal data to any other location by us.

 

3.3. Delete Your Data

You can delete all data stored by the Extension at any time by:

• Clicking the Settings icon in the Extension and selecting Disconnect to

remove your OAuth token and clear all cached data.

• Uninstalling the Extension, which removes all locally stored data from your

device.

• Managing or revoking access through your Google Account settings at

myaccount.google.com/permissions.

 

3.4. Disclosure of Your Data

We do not disclose your data to any third parties. As we do not collect or

store your data on our servers, there are no circumstances under which your

data would be disclosed by us to any other party.

 

3.5. Business Transactions

If the Company is involved in a merger, acquisition, or asset sale, we will

provide notice before any data handling practices change and update this

Privacy Policy accordingly.

 

3.6. Law Enforcement

Under certain circumstances, the Company may be required to disclose your data

if required to do so by law or in response to valid requests by public

authorities (e.g., a court or a government agency).

 

3.7. Other Legal Requirements

The Company may disclose your data in the good faith belief that such action

is necessary to:

• Comply with a legal obligation

• Protect and defend the rights or property of the Company

• Prevent or investigate possible wrongdoing in connection with the Service

• Protect the personal safety of users of the Service or the public

• Protect against legal liability

 

3.8. Security of Your Data

All data used by the Extension is stored locally on your device using Chrome's

secure storage APIs. We do not transmit your data over the internet to our

servers. Your calendar data is fetched directly from Google's servers to your

device using your authorized OAuth token. While we strive to use commercially

acceptable means to protect your data, no method of electronic storage is 100%

secure.

 

4. Miscellaneous

 

4.1. Children's Privacy

Our Service does not address anyone under the age of 13. We do not knowingly

collect personally identifiable information from anyone under the age of 13.

If you are a parent or guardian and you are aware that your child has provided

us with data, please contact us.

 

4.2. Links to Other Websites

Our Service may contain links to other websites that are not operated by us,

such as links to Google Calendar. We strongly advise you to review the Privacy

Policy of every site you visit. We have no control over and assume no

responsibility for the content, privacy policies, or practices of any

third-party sites or services.

 

5. Changes to this Privacy Policy

 

We may update our Privacy Policy from time to time. We will notify you of any

changes by posting the new Privacy Policy on this page and updating the "Last

updated" date at the top. You are advised to review this Privacy Policy

periodically for any changes.

Policy. You can revoke access to your Google Calendar data at any time through your Google Account settings or by disconnecting within the Extension.
