Methodology & data

Transparent, not a black box

Rule-based scoring

Every score comes from rules you can see and change in the editor. Even AI drafts stay normal, inspectable rules.

Point-in-time backtests

Index compositions are applied survivorship-bias-free; earlier periods are marked accordingly.

Market data from leeway.tech

Fundamentals and prices from a single source, updated daily.

Informational only

Simulations on historical data are not a guarantee of returns and not investment advice.

Frequently asked questions

What happens after the 7 trial days?

Nothing happens automatically: since we never ask for payment details, the trial simply ends and your account continues as Free.

Do I keep my data if I downgrade?

Yes, everything stays saved and nothing is deleted. Items above a Free limit are locked (lock icon): in each area, the entries you created first stay usable within the limit. You can delete locked entries anytime or unlock them again with Premium.

Are backtests a guarantee of returns?

No. A backtest is a model simulation on historical data. Useful for checking rules, but not a statement about the future and not investment advice.

Can I switch the billing period later?

Yes, anytime in your account. When switching to yearly, the month you already paid for is credited proportionally.
