Datemark – Privacy Policy

Last updated: 2025-11-14

Datemark (“the Extension”) is a Chrome extension designed to automatically extract event information from webpages and help users add these events to their Google Calendar.
This Privacy Policy explains what data we collect, how it is used, and how it is protected.

If you have any questions, you can contact us at: infodatemark@gmail.com

1. Information We Collect

1.1 Google Account Information (via OAuth)

When you authenticate with Google, we receive:

Your Google account ID (unique identifier)
Your email address
Permission to add events to your Google Calendar

We do NOT access:

Your emails
Your contacts
Your files
Your calendars other than writing events to the one you select

We only request the minimum OAuth scopes required to insert events into your Google Calendar.

1.2 Event Data

When you extract events from a webpage, Datemark processes:

Event title
Date and time
Location
Any additional structured details found in the page text

This data is processed temporarily to create calendar events.
Event data is not sold, shared, or used for advertising.

1.3 Usage Data (for usage limits)

We store minimal usage metadata in Google Firestore:

Your user ID
Number of events processed per month
Time of last usage reset

This is used solely to enforce the monthly free tier quota.

2. How We Use the Information

Your data is used exclusively for:

Creating calendar events in your Google Calendar
Providing the extension’s core functionality, including AI-based event extraction
Tracking usage limits to enforce fair usage
Maintaining and improving the Extension

We do not:

Sell your data
Share your data with third parties
Use your data for advertising
Use your data to train AI models outside your explicit usage

3. Google API Services User Data Policy (Limited Use Requirements)

Datemark complies with the Google API Services User Data Policy, including the Limited Use requirements.

Accordingly, the Extension:

Uses Google user data only to provide or improve the user-facing features described
Does not use Google user data for any other purposes
Does not transfer Google user data except to execute the user’s requested functionality
Does not use Google user data for advertising, profiling, or analytics unrelated to core features

4. Data Storage and Security

We store only minimal usage metadata in Google Firestore.

We do NOT store:

Your calendar contents
Individual events added to your calendar
Webpage content
Any personal information beyond what is strictly required for the service

All data stored in Firestore is protected using Google Cloud security standards, including:

Encrypted storage
Secured access via service accounts
Strict access rules

We do not share any personal information with third parties.

We may share aggregated, anonymous metrics (e.g., number of total events processed per month) purely for performance and usage analysis — never identifiable information.

6. Data Retention and Deletion

6.1 Retention

We retain:

Usage metadata (ID + monthly count) until your account is inactive for 12 months

6.2 Data Deletion

You can request that all stored data associated with your account be deleted by emailing us at:

📩 infodatemark@gmail.com

Your request will be processed within 30 days.

7. Permissions Used

Datemark uses the following browser permissions:

activeTab – to extract event data from the current webpage
scripting / content scripts – to analyze webpage content
identity / OAuth – to authenticate with Google
storage – to store minimal settings and preferences

These permissions are used exclusively to deliver the extension’s functionality.

8. Children’s Privacy

Datemark is not intended for use by individuals under 13 years of age.
We do not knowingly collect information from children.

9. Changes to This Policy

We may update this Privacy Policy as needed.
When changes are made, the updated date at the top will be revised.
