Privacy Policy

Last updated: 2026-10-06

This policy describes how WhatsCalendar (“we”, “the service”) handles information when you use our WhatsApp calendar assistant.

Information we collect

• WhatsApp messages — text you send to the bot, used to generate replies and run calendar actions.
• Conversation history — recent messages stored to maintain context (limited retention).
• Google OAuth tokens — stored securely after you connect Google Calendar, used only to access your calendar on your behalf.
• Calendar data — event titles and times retrieved or created when you request calendar actions.
• User preferences — optional name and timezone you provide.
• Technical logs — basic server logs for debugging and security (no message content sold or shared).

How we use information

• To respond to your messages and perform calendar actions you request.
• To maintain your session and preferences across restarts.
• To improve reliability and fix errors.

What we do not do

• We do not sell your personal data.
• We do not use calendar data for advertising.
• We do not access your Google Calendar without your explicit OAuth consent.

Data storage

Data is stored in a secured database (MongoDB). OAuth tokens and conversation data are associated with your WhatsApp identifier and are not shared with other users.

Third-party services

• Google Calendar API — calendar read/write after you authorize.
• Groq — processes message text to generate assistant replies.
• Hosting provider — runs the application infrastructure.

Revoking access

You can revoke Google Calendar access at any time in your Google Account permissions. Stop messaging the bot to discontinue use.
