Your books, kept in India and read-only by default.
TallyNexa stores your synced Tally books in India (Delhi data centre), encrypts them in transit and at rest, and separates each business at the database level. The connector only reads unless you switch write-back on, and Nexa AI never gets database access.
The facts
| Where data is stored | India (Delhi data centre) |
|---|---|
| Encryption in transit | TLS on every connection — the connector, the apps and the website |
| Encryption at rest | Encrypted at rest |
| Separation | Each business's books are separated at the database level |
| Who can see your books | Your accountant or CA sees only the companies you give them access to |
| Access to Tally | Tally's own local XML gateway — no TDL file is installed in Tally. Read-only by default; your Tally data file is never edited by TallyNexa. |
| Writing to Tally | Writing to Tally is off by default. A drafted voucher must balance and be approved before the connector posts it through Tally's own import. |
| Sync checks | After every sync, voucher counts, ledger counts and closing balances are checked back against Tally. |
| AI and your data | Nexa AI never gets database access. For each question it receives only the report results needed to answer it, and those results are not used to train AI models. |
| Certifications | No third-party certification (such as SOC 2 or ISO 27001) yet — we will say so here when one is completed. |
