Ideally monthly cash in and cash out for the last 6-12 months, plus the current balance and its date. Headline figures or a transactions CSV also work.

Does it make up growth rates for the scenarios?

No. The best and worst-case inputs come from you, and it asks if you have none. Any range it cites, such as fundraising lead time, is labeled approximate.

Does it work with accrual accounting?

Yes, but runway is a cash measure. If you give it an accrual P&L it will ask about collection timing and note the difference.
