Personal safety, reimagined
Invisible while you’re safe.
Loud when it matters.
Start a temporary Safety Session before you go. While you’re fine, nothing is shared. Miss a check-in and SEYFI releases exactly what you chose — to the people you chose. Encrypted in transit and at rest.
Safety without surveillance · 6 languages · No ads, ever
Four steps. Then you forget it’s there.
Start a session
Before you walk home, meet someone new, or head out alone — set how long, and who to tell.
Stay invisible
While you’re safe, nobody sees anything. Your location trail is encrypted on your phone.
Miss a check-in
If you don’t confirm you’re safe, SEYFI waits out a grace period — then acts, without you.
Contacts get the link
Your chosen people receive a secure link with exactly what you pre-approved. No app, no account.
Your calm, counted
Peace of mind you can see.
Every session SEYFI watches over is remembered — hours protected, people kept in the loop. Not a streak to chase. A quiet record of the times someone never had to wonder if you were okay.
“Thanks to SEYFI, the people who love you never had to worry.”
Everything, without watching you.
SMS alerts
Free plans notify contacts by email. SEYFI+ sends a text — faster, harder to miss, from a branded “SEYFI” sender.
Schedule ahead
Set a session for “tomorrow 13:00–16:00”. It arms itself on time even if your phone is asleep.
More trusted contacts
Free includes 3 trusted contacts. SEYFI+ raises that to 15.
Custom check-ins
Choose your own check-in rhythm and grace periods.
Quick-start
Repeat your usual session with one tap.
Priority delivery
Automatic failover across carriers so the message gets out.
Six languages
Speaks the way you do.
English, Français, Deutsch, Español, Italiano, Português — the whole app, not just the menus. Safety instructions read clearly in your language, because a stressed moment is no time to translate.
The promise
Safety without surveillance.
Most safety apps ask you to be tracked to be safe. SEYFI refuses that trade. While you’re fine, your location exists only as encrypted data on your own phone — unreadable to your contacts, and to us. It becomes readable to one chosen person only after a real release. That’s the whole design.
Simple, honest pricing.
The safety basics are free forever — the panic button is never behind a paywall.

Questions, answered.
Does SEYFI track me?
No. Nothing is recorded outside an active session, and even then your location is encrypted on your device. Nobody — not your contacts, not us — can see it while you’re safe.
What do my contacts need?
Nothing. They open a secure browser link. No app, no account, no sign-up.
What if my phone dies?
The release is decided by our servers, not your phone. A dead or offline phone still triggers the release when you miss your check-in.
Can I cancel a release?
Checking in as safe stops everything. Links also expire and are limited to a few views.
Is my private message really private?
Yes — it’s encrypted on your device and only ever decrypted after a genuine release, for the contact you chose.
Go. We’ll stay quiet.
Set a session in seconds. Forget it’s there. Know that if something goes wrong, the right people will know exactly what you wanted them to.
