Do I need to sign in or link a card?

No. You enter your usage yourself, and the values live only in the link. Nothing is stored on a server.

Where do the benefit values come from?

We prioritize official information as of the date shown (help center, sign-up page, notices). Where official confirmation is unavailable, we label press reports, reference material or estimates separately. Each item has a date and a source link. Benefits without a published amount use a typical value marked as an estimate, which you can edit on the result screen. Check each source and the latest official conditions.

Can I send my result to someone?

Copy the link on the result screen and send it. It opens the same result.
