Going somewhere that deserves a backup plan? A first date, a late walk home, a hike, meeting a stranger from the internet? SEYFI watches over you — without watching you.
START A SAFETY SESSION
Tell SEYFI how long you'll be out and who to alert. If you don't check in before your session ends, your trusted contacts automatically receive your last location, your private message, and a link with everything they need to help — even if your phone is dead, offline, or taken from you.
CHECK IN WITH ONE TAP
A gentle reminder, a single tap, and everyone who cares about you stays calm. Extend your session anytime if plans change.
THE PANIC BUTTON
Hold to trigger an immediate alert with your live location. It works with or without an active session, and it will always be free.
PRIVACY IS THE WHOLE POINT
• Your location trail is encrypted on your phone before it is uploaded.
• While you're safe it is not shared with anyone — not your contacts.
• Data is released ONLY if you miss a check-in or press the panic button.
• End your session safely and everything is discarded. Nothing to see, nothing to sell, no ads, ever.
SEYFI+ (optional)
Upgrade for convenience: alerts by SMS from a branded sender, sessions scheduled ahead ("tomorrow 13:00–16:00"), up to 15 trusted contacts, and custom check-in rhythms. Free for the first 3 days. The safety basics stay free forever.
Safety without surveillance. That's the promise.
