IT admin guide

For Microsoft 365 administrators deploying Hindi Converter in an office, department or institution.

Summary

Centralized Deployment

Before you start, check Microsoft’s requirements for Centralized Deployment of add-ins (users signed in with work or school accounts, supported Office builds).

1. Sign in to the Microsoft 365 admin center as a Global admin, or an Exchange admin with Application admin rights.
2. Go to Settings › Integrated apps and click Get apps.
3. Search for Hindi Converter, open it and click Get it now.
4. On Add users, choose Just me (for a test first), Entire organization, or Specific users/groups.
5. On Accept permissions, review the screen. The add-in requests no Microsoft Graph or other delegated permissions.
6. Click Finish deployment.
7. Changes can take up to 24 hours to reach users. Users may need to restart Office. The button appears on the Home tab of Excel, Word and PowerPoint.

To remove: Settings › Integrated apps › Hindi Converter › Remove app. To change who has it: open the app there and edit Users.

Recommended: deploy to yourself or a small test group, check it works on your Office builds and network, then widen.

If you block the Office Store for users

Centralized Deployment still works when users cannot install add-ins themselves.

Signing in to buy or restore a plan

Buying happens in the user’s browser on hindiconverter.com, with a Google or Microsoft account. If a work or school account shows “Need admin approval” on the account page, your administrator can approve the sign-in app in the Microsoft Entra admin center, or the user can buy with a personal Google or Microsoft account instead. For one invoice for several users, email [SUPPORT EMAIL].

Licensing and billing for organisations

• Each computer (each Office app on it) gets its own free trial the first time the add-in opens, with no sign-in (7 days or 10 large conversions, whichever comes first). At most 20 new trials start from one network address in 30 days, so a large office behind one address may reach that cap; email [SUPPORT EMAIL] if that happens.
• After the trial each user needs a plan, bought with a Google or Microsoft account of their choice (1, 6 or 12 months, paid once, no auto-debit). Users can pay individually, and each payment gets a GST invoice that can carry your organisation’s name and GSTIN.
• Office licence: ₹4,500 for 12 months, incl. GST, one payment, covers 3 people (3 Google or Microsoft accounts). The buyer pays on the account page (opened from the pane) and then sees a 12-character office code in the pane and on the account page. The other people click “Already bought, or have an office code? Sign in” in their pane, sign in on the account page, open “Have an office code?”, type the code and click Join. Only the buyer sees the code. The buyer takes one of the 3 places. Renewing extends everyone. If all places are taken, a 4th person cannot join; email [SUPPORT EMAIL] to free a place.
• One computer at a time: each person's plan, trial or office place works on one computer at a time. On a new computer, users sign in with the same account; a button then moves the plan there, and the other computer locks. Moves are limited to 3 per Office app in any 30 days. “Sign out” in the pane frees a computer’s place without using a move.
• For more than 3 users, one invoice for several plans, or purchase orders, email [SUPPORT EMAIL].

Data handling

• Document content: processed only inside the add-in’s web view on the user’s device using Office.js. Not transmitted, not logged, not stored by us.
• Licence check: the add-in sends only its random install ID and the Office app name over HTTPS to our licence API, which returns the trial / licence status as a signed licence. No sign-in token is sent from inside Office.
• Sign-in: only in the browser, on the account page, when a user buys or restores a plan. Google or Microsoft returns an ID token with name, email and account ID, which we verify and do not store.
• Install ID: the pane keeps a random install ID in that computer's browser storage for the add-in. It runs the free trial and, once a plan is linked, makes the plan work on one computer at a time. It is not a hardware serial number and cannot identify the machine outside our add-in. Clearing Office's web cache or reinstalling Office may create a new ID and start a new trial.
• Stored records: per install, the install ID, Office app name, trial dates and count, and a salted one-way hash of the IP address (the raw IP is not stored). Per account, the Google or Microsoft account ID, email, name, the 10-digit mobile number the user enters at checkout (required by Cashfree for every order), plan and dates, office licence membership, Cashfree order and payment IDs, and billing details for invoices.
• Payments: on the account page, using Cashfree Payments’ checkout, opened in the user’s browser. The mobile number is passed to Cashfree to create the order. We never receive card, UPI or bank credentials.
• Settings (output font, protected words, options) are stored locally in the add-in’s browser storage on each device.
• Retention and deletion: see the Privacy Policy. To remove the records of your users, email [SUPPORT EMAIL] from an admin address listing their email addresses.
• Hosting: add-in files served via Cloudflare; licence server on [SERVER / DATABASE HOST]. Data may be processed outside India as described in the Privacy Policy.

Network endpoints

If your network uses a firewall, proxy or SSL inspection, allow HTTPS (port 443) to:

Office itself also needs its usual Microsoft 365 endpoints; see Microsoft’s Microsoft 365 URLs and IP address ranges.

If the licence API cannot be reached, the add-in keeps working on its last verified licence for up to 7 days after the last successful check, then conversion locks until it can reach the server again. Scan and Undo always keep working.
