App: Is Jet d'Eau On? · Last updated: 12 June 2026
Is Jet d'Eau On? does not collect, store, or share any personal data.
None. The app has no accounts, no login, and no analytics or tracking SDKs. We do not collect your name, email, location, device identifiers, or usage data.
The app displays whether Geneva's Jet d'Eau fountain is currently running, plus local weather. To do this it requests a small status summary from our server (jd.mentisphere.wiki). That server derives the on/off status from the public webcam operated by Services Industriels de Genève (SIG) and current weather from Open‑Meteo. Standard network logs (such as IP address) may be processed transiently by the server to deliver the response and are not used to identify or track you.
The app itself contains no third‑party advertising, analytics, or tracking. Weather data is provided by Open‑Meteo; fountain status is derived from the SIG public webcam.
The app is suitable for all ages and does not knowingly collect data from anyone.
If this policy changes, the updated version will be posted on this page.
