Precise location stays on your iPhone.

Jolt is operated by 21 Media LLC. For privacy questions, contact admin@21media.to.

If you allow location access, Jolt uses Apple location services to center the map and sort earthquakes and evacuation sites by distance. Precise latitude and longitude are processed on your device and are not sent to or stored by Jolt's servers.

Jolt requests earthquake and tsunami information from the Japan Meteorological Agency and evacuation-site data from the Geospatial Information Authority of Japan. These public services may receive the IP address and ordinary network request information needed to return the data.

If you allow notifications, Jolt sends a random installation ID, a registration secret that is stored as a cryptographic hash, Apple Push Notification Service and Live Activity tokens, language, time zone, monitoring scope, selected prefecture, and minimum Shindo. Jolt uses this data to deliver earthquake and tsunami alerts and Live Activities that match your settings. Jolt does not create an account.

Cloudflare processes Jolt's alert service and notification registration data. Apple provides location services, MapKit, Apple Maps, push notifications, and Live Activities. Netlify hosts this website and may process standard request information, such as IP address and browser details, to deliver its pages. Jolt does not add analytics, advertising, or tracking scripts to this website.

Notification registration data is kept while alerts are enabled and the registration remains active. If you turn off notification permission and reopen Jolt, the app requests deletion of its notification registration. Delivery records are deleted after 30 days, and registrations that have not refreshed for 365 days are deleted. Contact support if you want an earlier deletion.

If you email support, we receive your email address and message so we can respond. The message remains in the recipient mailbox for as long as needed to answer and document the request. You can ask us to delete it.

Jolt does not track people across other companies' apps or websites, show behavioral advertising, or sell personal data.
