Specter

Privacy-first fitness tracking. The Signal of Strava.
Beta Program
Private Beta · Invite Only

Fitness tracking for people who can't afford to be tracked.

Specter is a working product, not a pitch. iOS, Android, Apple Watch, Wear OS, and Garmin -- all built around a privacy architecture that treats your location data as classified by default.

Apply for Beta Access Why Specter?

The Problem

In 2018, Strava's global heatmap exposed the locations, patrol routes, and daily patterns of military and intelligence personnel on classified installations worldwide. The fitness app they used for personal health became an open-source intelligence tool against them.

That vulnerability hasn't been fixed. It has gotten worse. Every major fitness platform still collects, aggregates, and in many cases sells location data.

"The Strava heatmap appears to be revealing the locations of military bases and secret outposts worldwide... including patrol routes, isolated facilities, and overseas deployments."
The Washington Post · January 2018

For security professionals, diplomats, law enforcement, and their families, the choice today is binary: accept the exposure, or stop tracking your training entirely. Specter is the third option.

How Specter Is Different

Most apps treat privacy as a feature. Specter treats it as the architecture. Compare what's enforced by default:

Capability Strava Specter
Routes encrypted at restNoAES-256
Coordinate obfuscation by defaultNo+/-500m
Cover Locations (route transposition)NoPatent Pending
Cryptographic deletionSoft deleteRandom overwrite
Per-person, time-limited share grantsNoYes
Default visibilityPublicTrust circles only
Location data sold to third partiesYesNever
Business modelSubscription + dataOne-time purchase

Cover Locations

The feature that changes everything. Take your real GPS route and re-project it onto a different city's road network.

How Route Transposition Works

Patent Pending
Your Real Route
What's Shared (Lisbon)

You run laps around your neighborhood. What gets shared shows you running through the streets of a different city. Distance, pace, and elevation profile preserved exactly. The actual geography completely severed.

Why This Matters

This is not coordinate jitter. Cover Locations eliminates the link between route shape and real geography entirely, closing the exact attack vector that made StravaLeaks possible.

What You'll Be Testing

Privacy at a Glance

Every Specter account has a privacy tier that controls who sees your data. Cryptographically enforced at every layer.

Tier Your Stats Your Location Best For
Ghost Trust circles only Never shared Maximum operational security
Stealth Public Trust circles + explicit grants Share performance, protect routes
Social Public Cover Locations + grants Compete without exposing geography
How Location Privacy Works

GPS tracks are AES-256 encrypted at rest. Start and end coordinates are jittered by up to 500 meters to prevent home/office inference. Route data is only accessible via an explicit, revocable ShareGrant. Default is deny.

How the Beta Works

Two weeks of real testing. Direct feedback to the founder. No support tickets vanishing into a queue.

  1. Sign in with Google or Apple Same account you'll use in the app. We only ask for name and email.
  2. Tell us about your setup Phone platform, watch platform, how you'll use the app. Takes 30 seconds.
  3. Get the app on your devices TestFlight invite arrives by email. Wearable companion installs automatically.
  4. Train normally for two weeks Long runs, intervals, recovery days. Whatever your pattern looks like.
  5. Submit structured feedback Per-feature reports through the portal. Bug reports auto-include device info.
Confidentiality

The beta program is confidential. No screenshots, feature descriptions, or access credentials shared outside the program without written permission. You'll review the full Beta Tester Agreement before completing registration.

Built Specter because the problem is personal. The fitness apps friends and colleagues used were the same apps that exposed bases in 2018, and nothing changed in the years that followed. Specter is the answer.
