FAQ
Questions about your data.
Is the connection to my accounts really read-only?
Yes. Access is granted through your accounting provider's own secure sign-in, and Nella requests read permission only. It cannot create, edit, move or delete anything in your books.
Is my financial data used to train AI models?
No. Your figures are never used to train AI models. They are used to answer your questions and build your insight pack, and nothing else.
Do you store a copy of my ledger?
No. Nella does not store your ledger. Your data is encrypted in transit, and Nella reads your live figures from your accounting platform when it needs them.
Can I delete my data?
Yes, at any time. Disconnect and request deletion and everything goes — one request, no retention period to wait out, no card on file to cancel.
What happens if I disconnect Nella?
Nella immediately loses access to your figures; the read-only permission is revoked from your accounting platform's own connected-apps settings, exactly like any other connected app. You can also ask for your data to be deleted at the same time.
Do I need to enter card details to try Nella?
No. The 60-day trial takes no card details, so nothing can be charged automatically and there is no subscription to remember to cancel.
