Privacy Policy

Calendario ("the extension", "we", "us") is a Chrome extension built and operated by Gaurav Suthar. This policy explains what data Calendario accesses, how it is used, and the choices you have. If you have questions, contact gaurav.suthar161@gmail.com.

How Calendario works

Calendario connects directly to Google Calendar and/or Microsoft 365 (Outlook) using each provider's official APIs and your explicit sign-in. There is no intermediary server sitting between your browser and Google or Microsoft — your calendar data is requested by the extension running in your browser and displayed to you, and nothing else in between reads or stores it.

What we access

• Calendar data — event titles, times, locations, descriptions, attendees, RSVP status, and attachments for the calendars you choose to connect and sync.
• Account identity — your name, email address, and profile picture, as provided by Google/Microsoft sign-in, used only to show which account is connected.
• Extension preferences — theme, language, time format, and which calendars are enabled.

Where your data is stored

Your OAuth access tokens and preferences are stored locally in your browser (via chrome.storage) on your device. Calendar data itself is fetched on demand from Google/Microsoft and rendered in the popup — Calendario does not operate a backend database, and we do not upload, copy, or retain your calendar content on any server we control.

Analytics

We use Google Analytics to understand aggregate feature usage (for example, which settings are used or how often the popup is opened) and to fix bugs. This telemetry is limited to anonymized product usage events and basic technical information (such as browser version and extension version) — it never includes the content of your calendar events, attendee information, or account credentials. We also see aggregate install and rating statistics that the Chrome Web Store provides to all developers; this data is controlled by Google, not Calendario.

Sharing and third parties

We do not sell your data or share it with advertisers. Data only flows to:

• Google (Google Calendar API, Google sign-in, Google Analytics)
• Microsoft (Microsoft Graph API, Microsoft 365 sign-in)

Each provider's use of data is governed by its own privacy policy — Google's and Microsoft's — in addition to this one.

Your choices and controls

• Disconnect a Google or Microsoft account at any time from Calendario's settings — this revokes the extension's access token.
• Revoke Calendario's access directly from your Google Account or Microsoft Account security settings at any time.
• Uninstalling the extension removes all locally stored tokens and preferences from your browser.

Data retention

Locally stored tokens and preferences persist only as long as the extension remains installed and connected. Disconnecting an account or uninstalling the extension deletes this local data immediately; nothing is retained on our side because nothing is stored there in the first place.

Children's privacy

Calendario is not directed at children under 13, and we do not knowingly collect data from them.

Changes to this policy

If this policy changes, the "Last updated" date above will be revised. Material changes will be reflected here before they take effect.
