Your spreadsheet never leaves your device.
Blunion analyses your file inside your own browser. The contents of your workbook are never uploaded, never sent to a server, and never stored by us. This is the core of how the product is built, not a setting.
What stays on your device
The entire analysis, parsing, every calculation, charts, and the deck, runs locally. No row of your data is transmitted. If your network is off after the page loads, the analysis still works.
What we do store
Only your account details, name, email, phone, company, designation, and your coarse location (city and state, from your connection, not GPS) to run your subscription and prevent abuse. Never your files.
Consent and control
We collect account data with clear notice and your consent, use it only to run the service, and honour your rights under India's Digital Personal Data Protection Act, 2023. You can request access or deletion at any time.
In transit and at rest
Account data moves over TLS and is stored encrypted. We never store payment card details, payments are handled by our PCI compliant gateway. Access is least privilege and logged.
The precise promise
We say two different things, and we keep them separate on purpose:
- Your files: analysed on your device, never seen, uploaded or stored by Blunion.
- Your account: the details above are stored securely so we can run your subscription, bill you, and keep the service fair. This is standard for any paid product and is governed by our Privacy Policy.
Keeping it fair and genuine
Access is tied to one account and one active device at a time. Work and college emails are verified before a free month starts. The application only runs when licensed to your organisation, which is how we keep copies and clones from operating on our name and infrastructure.
