location-sharing

Location sharing transmits a user’s real-time or on-demand GPS position to chosen recipients — the feature that lets a Panic Button mean “come and get me, here.” It is one of the most protective capabilities in safety tech and one of the most dangerous: the same mechanism, in the hands of an abuser, becomes Location Tracking Abuse. Privacy-focused tools such as Círculo respond by encrypting location and sending it only to a Trusted Network, never tracking or exposing it.

Privacy and Safety

Privacy and safety are often treated as the same goal in anti-violence technology, but for a Victim-Survivor they pull in opposite directions and must be balanced deliberately. The data that makes a safety tool useful — real-time Location Sharing, cloud backups, message logs kept as Evidence Documentation — is exactly the data an abuser will try to reach if they retain access to a device, account, or family plan. NNEDV’s Safety Net Project frames technology safety as protecting “safety, privacy, accessibility, and civil rights” together, and stresses that the burden should fall on holding perpetrators accountable, not solely on survivors restricting themselves. Yet practical safety planning still requires hard privacy choices: which device is trustworthy, which accounts are compromised, and what should never be stored where an abuser can find it.

This is why every safety app sits in tension here. A design that collects rich location history to “build evidence” also builds a honeypot that Stalkerware or a coercive partner can exploit, and the Datafication of MeToo critique shows how such collection can become extraction rather than protection. Privacy-protective alternatives respond with data minimisation, on-device storage, encryption, and Discreet Access, and safety guidance cautions that even removing monitoring can escalate danger if an abuser feels they’ve “lost control.” Getting this balance right is the central problem of Survivor-Centered Design and Trauma-Informed Design.

Location Tracking Abuse

Location tracking abuse is the covert or coercive use of a person’s geolocation against them — through GPS apps, “find my” services, shared family-plan settings, vehicle telematics in smart cars, or cheap Bluetooth trackers slipped into a bag or car. It is the dark inversion of Location Sharing: the very mechanism that lets a Panic Button say “come and get me, here” becomes, in an abuser’s hands, a way to know where a Victim-Survivor is at all times. NNEDV’s Safety Net Project warns that in some tragic cases GPS devices and apps have aided an offender in locating a victim to commit murder, or were enabled without the victim’s knowledge. It is a core tactic of Coercive Control and a primary engine of Stalking.

The tracking can be installed directly via Stalkerware, surfaced through accounts the abuser still controls, or carried out with commodity hardware never designed for surveillance — a problem severe enough that Bluetooth trackers like AirTags prompted dedicated anti-stalking detection features and Congressional attention. Because removing a tracker can signal to an abuser that they have “lost control” and trigger escalation, technology safety planning treats discovery and removal as something to do carefully with an advocate, not impulsively. This is why location features in Personal Safety Apps such as Círculo encrypt position data and send it only to a Trusted Network, rather than logging or exposing it.

Personal Safety Apps

Personal safety apps are mobile applications that help a user summon help, share their whereabouts, or deter harm. Most combine a Panic Button, Location Sharing, and a Trusted Network, and many connect to Crisis Hotlines and Resources. They span two broad postures: alarm-and-summon tools aimed at acute danger, and network-and-intervene tools rooted in Bystander Intervention that aim to prevent harm before it escalates.

The central design tension is Privacy and Safety: the same capabilities that protect (continuous location, contact lists, always-on microphones) can be turned against a user — see Location Tracking Abuse and Stalkerware — so survivor-facing tools must be weighed with Trauma-Informed Design in mind.

Trusted Network

A trusted network is the set of people a user pre-selects to receive alerts, check-ins and location from a safety app — Circle of 6’s and Círculo’s “circle” of six, On Watch’s “support network.” The design choices that matter are who can be added, how easily the list can be changed under duress, and whether contacts can actually help in time. It is the connective tissue that makes Bystander Intervention work in software.

Círculo (En Círculo)

Summary

Círculo is the privacy-hardened successor to Circle of 6, built for journalists, activists and human rights defenders — and grounded in the experience and concerns of the women who occupy central roles in journalism, social movements and human-rights defence. It keeps Circle of 6’s core idea — a self-chosen network of six trusted peers — but rebuilds it for high-risk work: members agree on safety protocols, form a social agreement about what they need from each other, then use the app to ask for help, share status, and send encrypted location updates that go only to their circle.

Its design centre is wellbeing and digital safety: encrypted conversations, no email or phone number required to sign up, lock and disguise features, no histories stored, and location that is encrypted and never tracked or exposed by the app. The makers are explicit that the app does not provide emergency response — it helps a person inform their community and signal what they need, and it requires an internet connection. By reducing isolation it aims to mitigate the burnout, trauma and self-censorship common in these fields.

panic-button

Panic Button

A panic button (or SOS trigger) is the central primitive of most Personal Safety Apps: a single fast action — a screen tap, a hardware-button sequence, a voice command, or a wearable press — that raises an alarm and usually shares the user’s whereabouts with a Trusted Network or emergency dispatch. Design tensions include speed versus accidental triggering, and visibility versus the need for discreet activation under threat.
