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, evacuation sites, and live cameras 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, evacuation-site data from the Geospatial Information Authority of Japan, and a current camera catalog from Jolt's service. When you open a live camera, your iPhone connects directly to the current provider, the Japan Coast Guard. These services receive the IP address and ordinary network request information needed to return the data or video. The app does not send a record of which camera you watch to Jolt's servers.

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.

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 send feedback from the app or email support, we receive your email address, message, and the app version, iOS version, and language details visible in the draft before you send it. We use this information to respond and investigate the request. 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.
