TatvaOS One

Mail, meetings, calendar, files and your people - your whole organisation in one app, behind one sign-in. Built and hosted in India.

TatvaOS One is your organisation's workspace on your phone: mail, meetings, calendar, files and people, behind one sign-in. Built and hosted in India by Techvein.

A person exists once. One account reaches every product - and when someone leaves, one action ends their access to all of it.

MAIL Business email on your organisation's own domain. Conversations, categories with colours, and filter rules applied at delivery. Shared mailboxes with send-as. Search across every folder.

CONNECT Meetings that belong to the organisation, not to whoever started them. Live meetings come first in the list, so you join the one that is happening. Guests join with a link - no account needed.

CALENDAR Day, week, month and agenda views. Recurrence and reminders. Invitations that work with Gmail and Outlook in both directions.

SPACE Files for you, your team and the whole organisation, out of the same allowance as your mail.

PEOPLE See who is in today, apply for leave, and check in or out of work.

ACCOUNT AND SECURITY Two-step verification, every signed-in device listed, and an alert when a new one signs in. Organisations are kept apart by the database itself.

TatvaOS One needs an account from your organisation's administrator. To bring your organisation to TatvaOS, visit tatvaos.com.
