## Licence: what we may do with it

**IPMA open data (api.ipma.pt)**: IPMA's own terms on api.ipma.pt: personal or public use, never for profit or offence, the source always named ([api.ipma.pt](https://api.ipma.pt/), read 11:28 UTC, 11 Nov, stated on the page).

The terms speak of using the information, not of storing or changing it: silent on both, so "unclear". No profit-making purpose. The full reading is incident.ipma@'s (sources/ipma/).
