How do I connect my books?
Sign in, open Settings, then Integrations, and choose QuickBooks Online or the other accounting platform listed there (Add another source lists every tool you can connect). You approve the connection on their own sign-in page and come back to LightSignal. After QuickBooks connects, the first read of your books usually takes about 20 minutes. You can disconnect a tool from the same place at any time.
What is the sample business?
It is a made-up business with generated books that shows how LightSignal reads a business. Every page that shows it carries the label "Sample business: every number here is made up". It holds no real customer's data.
How do I cancel?
Go to Settings, then Billing, then Open billing portal. On that page, with our payment provider Stripe, you can cancel your plan: it stays active until the end of the period you have paid for, and you are not charged again. Deleting your account instead cancels your subscription the moment you start the deletion, with no further charges.
How do I delete my account?
See Delete your account for the steps on the web and in both apps, what is deleted and when, and what we keep.
How do I get a copy of my data?
Sign in on the web and open Settings, then Data & Privacy. If you don't see a download there, or you can't sign in, email hello@lightsignal.app from the address on your account and ask for a copy.
