Terms of use
Last updated: 21 October 2026
1. What the service is
DetourData is a free information service run by Andrea Somenzi. It lists the risks that regularly disrupt travel in Italy and have been announced, forecast or scheduled by others, with links to the original sources. It is informational only.
2. Warnings belong to their authorities
Weather and civil-protection warnings, strike notices and other items are issued by the authorities and organisations named on each entry. We relay them without altering their content. Entries we enter by hand (protests, high-risk football matches, heat-wave bulletins, energy strikes) are written by DetourData from the announcement each one links to. In case of any difference, the source's own publication prevails; always check it before acting.
3. Our impact statements are general
The travel-impact text on each entry is written by DetourData from published rules. It describes what may typically happen; it is not advice for any particular person or trip. Being aware of a risk does not make a trip safe, and what actually happens can differ from what was announced. Decisions about travel remain yours.
4. No duty of care, no guarantee
We try to be accurate and timely, and we publish our accuracy record, but we do not guarantee that the service is complete, correct, current or available. Sources can be late, change or stop. To the extent permitted by law, we are not liable for losses arising from use of, or reliance on, the service.
5. Reusing our data (API and calendar feeds)
You may use the public API and the calendar feeds, including to show entries on your own site, provided that you: credit DetourData with a link; keep each entry's source attribution as we give it; do not alter the warning content or present our impact text as the authority's; and respect the rate limits. Some sources restrict commercial reuse — the sources page lists each one's terms, and those terms apply to you too.
6. Emails
Emails are sent only after you confirm your address, and every email lets you change your preferences or unsubscribe. See the privacy notice for how your data is handled.
7. Law
These terms are governed by Italian law. For consumers, the competent court is that of your own place of residence; for any other dispute, the court of Brescia, Italy has jurisdiction.
