JustGym is built by CHRSMA. This page covers the marketing site (justgym.fit). The app (app.justgym.fit) collects training data under the same principles: we collect the minimum, we don't sell any of it, and you can have it deleted by asking.

What we collect on this site

Your email, if you join the founding-tester list — plus the page you signed up from, the referring site, your browser's user-agent string, and a referral code if a friend's link brought you here.
Your question and optional email, if you ask one in the FAQ section.
Anonymous usage analytics via Google Analytics 4 — pages viewed and buttons clicked. GA sets cookies for this; we see aggregate behavior, not you.
A referral code in your browser's local storage (only if you arrived through a share link), so the friend who sent you gets credit when you sign up. It never leaves your browser except inside your own signup.

What we use it for

Sending you the founding-tester welcome and invite emails (sent via Resend from the justgym.fit domain).
Feedback and surveys about the alpha — that's what the list is for, and that's all it's for.
Answering your FAQ question; answered questions appear publicly, never with your email.
Knowing which shared links bring people in, so founding-tester referrals can be credited (including retroactively, once perks exist).

What we never do

Sell, rent, or share your email or data with third parties for their marketing. Ever.
Send you anything unrelated to JustGym.
Expose your email publicly — community questions are published without any identifying information.

Where it lives

Signups and questions are stored in our database hosted by Supabase. Emails are delivered through Resend. Analytics are processed by Google Analytics. Each processes data on our behalf under their own security terms; none of them may use your data for themselves.

Deletion and questions

Want off the list, your question removed, or a copy of what we hold? Email hello@justgym.fit from the address in question and it's done — no forms, no waiting period beyond the time it takes us to read it.
