Disclaimer and privacy
Last updated 27 July 2026
IronScript is something I built for my own training and share for free. This page explains what it is not meant to be, and what it does with your data.
Not medical or health advice
IronScript is a tool for planning and keeping track of your training and food. It is not medical, health or nutrition advice, and it does not know anything about your body or your health.
The numbers it shows, such as an estimated one rep max, are rough figures worked out from what you log. They are estimates, not measurements.
Training and diet carry risk. Talk to a doctor, trainer or dietician before you start something new, and stop if something hurts. You use the app and follow your own plan at your own risk.
Your data stays on your device
When you use IronScript without signing in, everything you create stays only on the device you are using. That includes your workouts, timers, routines, workout history, food schedules and logs, body weight and settings. It never leaves your device and I cannot see it.
Clearing your browser data or removing the app deletes that local data.
When you sign in
Signing in is optional. It exists so your data can sync across your phones and the web. Sign in and sync run on Google Firebase, using Firebase Authentication and Cloud Firestore. Your synced data is stored in Firestore under your own account id.
- You can sign in anonymously, which is a private id with no personal details attached.
- You can sign in with a Google account. If you do, Firebase receives your Google account details, such as your email address and name, to identify you and keep your data linked to you.
- What syncs: your workouts, timers, routines, workout history, food schedules and logs, body weight and app settings.
What I do not do
- No ads.
- No analytics or tracking, on the app or on this site.
- I do not sell or share your data with anyone. The only place your synced data goes is Google Firebase, which stores it for you so sync works.
Google Firebase
Because sync relies on Google Firebase, the data you sync is handled on Google servers. How Google handles it is covered by their own privacy policy, which you can read at firebase.google.com/support/privacy and policies.google.com/privacy.
Removing your data
- Local data: clear your browser data or remove the app from your device.
- Synced data: sign out to stop syncing. To have your synced data deleted from Firebase, get in touch and I will remove it.
Changes to this page
If I change how any of this works, I will update this page and the date at the top.
