Privacy Policy — Quasar Calendar Bot

Last updated: 5 June 2026

Quasar Calendar Bot (“the Bot”, “we”) is a Telegram bot operated by Quasar Studio that creates events in your Google Calendar from messages you send it. This policy explains what data we access and how we handle it.

Information we access

We do not request access to read your existing calendar entries, contacts, email, files, or any other Google data.

How we use it

When you send the Bot a message describing an event, we parse the date, time, title and location and call the Google Calendar API to create that single event in your calendar. That is the only use.

What we store

To keep your connection active without asking you to sign in every time, we store a Google OAuth refresh token and your account email, associated with your Telegram chat id, in a secured configuration store (Vercel Edge Config). We do not store the contents of your calendar or the events we create.

Sharing

We do not sell, rent, or share your data with third parties. Quasar Calendar Bot’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Data retention and deletion

You can disconnect at any time by sending /disconnect to the Bot, which deletes the stored token. You can also revoke the Bot’s access directly at myaccount.google.com/permissions. Revoking access invalidates the stored token immediately.

Security

Tokens are kept in a secured store and transmitted over HTTPS. They are used only to call the Google Calendar API on your behalf to create events you requested.
