Geo-fenced phone compliance

Student phones that call home,
not scroll away.

LockDown locks student smartphones to 911 and parent-approved numbers only while on school grounds. No pouches. No physical management. Just a clean software layer that satisfies state mandates.

How it works

Three steps to full compliance

No hardware to buy, no pouches to manage, no student training required. LockDown deploys in days, not semesters.

School sets campus geofence

Admin draws the campus perimeter on a map. LockDown uses GPS to detect when students enter school grounds. No beacon hardware needed.

Parents configure contacts

Each family links up to 4 parent/guardian numbers. Students can always call home. Everyone else — social media, games, browsing — is locked out.

911 stays always-unlocked

Federal law requires it. We enforce it. 911 is never blocked, regardless of geofence status. Every other function respects the school zone boundary.

* 911 is always accessible. Text messaging is disabled on campus to meet the "basic telephone" exemption in most state laws.

State mandate ready

Built for the law as written

Phone-Free School Act (AB 3216)

Requires districts to restrict smartphone use unless for "emergency or other purposes." Exempts devices that support "voice calling only" — exactly what LockDown enforces.

Bell-to-Bell Restriction (2025)

New York requires bell-to-bell prohibition on personal internet devices. LockDown's geo-fence maps to the school day with zero admin intervention required.

Legislative Bill 140 (signed May 2025)

Nebraska requires districts to prohibit student phone use on school property. LockDown gives districts a turnkey implementation path with GPS enforcement.

Distraction-Free Learning Act (HB 379)

First state in the nation to enact bell-to-bell restrictions. Florida districts using LockDown meet full compliance with no pouch management overhead.

+ 30 more states with active or pending legislation. LockDown is built to track and support each state mandate as it passes.

Yondr pouch cost per student (one-time, easily lost or damaged)

LockDown per-student hardware cost. Pure software.

1,000+

students at a typical high school. Yondr cost: $15,000–$25,000. LockDown: a fraction of that.

78%

of parents want their child to have emergency phone access at school, per National Parents Union polling.

LockDown satisfies parents and legislators simultaneously. Not a compromise — both.

Schools have been solving the wrong problem.

The question isn't whether to restrict phones — every state has answered that. The question is whether to spend millions on magnetic pouches that students defeat, or deploy a software layer that works every time, for every student, with zero hardware overhead. LockDown is the second option.

Geo-fence. Lock. Protect.
