Privacy policy

Last updated: 2026-11-12

Who we are

Flux is operated by TCC Software LLC. If you have a question about your data, email tccsoftwarellc@gmail.com.

What we collect

  • Account details, through our sign-in provider Clerk: your name, email address and sign-in data.
  • Your profile: FTP and other thresholds, heart-rate zones, weight, age, weekly availability and equipment.
  • Training data: planned workouts, training plans, races, strength sessions, and rides with their recorded data (power, heart rate, cadence and GPS).

Where it comes from

From you, and from the services you choose to connect: Strava, Hammerhead and Wahoo. Flux imports your rides from them and, for Hammerhead and Wahoo, sends your planned workouts to your device.

Disconnecting a service stops future syncing. Rides already imported stay in Flux until you delete them.

Connected AI apps

You can connect an AI app such as Claude or ChatGPT to Flux. Nothing is shared until you sign in to Flux and approve the connection.

  • What it can read: your profile, including health-related data (heart rate, weight and age), plus your rides, calendar and plans.
  • What it can change: your workouts, plans, races and profile settings. It can't change rides or sessions you've already completed, and it can't delete anything without first showing you what will go and getting your OK.
  • Turning it off: go to Settings → Connected apps and choose Disconnect. It takes effect immediately. The list of changes each app made stays visible in Flux.
  • Who processes it: Flux runs no AI model over your data. The AI app you connect processes what it reads under its provider's own terms and privacy policy.

How we use it

Only to run Flux: your calendar, device sync, ride analysis and records. We don't show ads, and we don't sell your data.

Where it's stored

In a PostgreSQL database hosted by Neon and on servers run by Railway, both in the eastern United States. Account and sign-in data is held by Clerk.

Deleting your data

Email tccsoftwarellc@gmail.com from the address on your account and we'll delete your account and all your data within 30 days.

Changes to this policy

When we change this policy we'll update the date at the top. For material changes, we'll also tell you in Flux.
