Privacy Policy

Last updated: July 5, 2026

Muscle Activation Coaching ("MAC", "we", "us") operates the MAC Coaching website, web app, and mobile app. This policy explains what we collect, why, and the choices you have. The short version: we collect what's needed to coach you, we don't sell your data, and you can ask us to delete it at any time.

What we collect

• Account information — name, email address, and a securely hashed password.
• Training and wellness content you choose to share — movement videos for body scans and replay analysis, progress photos, body measurements, workout logs, nutrition logs and food photos, and messages you send Coach Thomas. This can reveal information about your physical condition; we treat it as sensitive and it is only used to provide your coaching.
• Purchase records — what you bought and your subscription status. Card numbers go directly to Stripe, our payment processor; we never see or store them.
• Usage basics — points, streaks, course progress, and app diagnostics that help us fix problems.

How we use it

• To deliver the services you ask for: AI movement analysis, program generation, nutrition estimates, course access, and coaching from Coach Thomas.
• To process purchases and manage subscriptions.
• To send service emails (verification codes, receipts, replies, and reminders you'd expect). You can opt out of non-essential email by replying "unsubscribe".

AI processing

Videos, photos, and text you submit for analysis are processed by our AI infrastructure provider (Groq, Inc.) to generate your results. Content is sent for processing only — we do not permit it to be used to train third-party models.

Who else touches your data

Only service providers who host or process it on our behalf: Stripe (payments), Groq (AI processing), Cloudflare (media storage), MongoDB Atlas (database), Brevo (email delivery), and Render/Vercel (hosting). We do not sell or rent your personal information to anyone.

Your photos and videos are private

Progress photos, scan clips, and replay videos are visible only to you and MAC coaching staff. They are stored access-controlled and served through short-lived, signed links.

Keeping and deleting data

We keep your data while your account is active. Email info@muscleactivationcoaching.com from your account address to request a copy of your data or full deletion — we complete deletion requests within 30 days, except records we must keep for tax and payment law.

Security

Data moves over encrypted connections (HTTPS), passwords are hashed with bcrypt, and media is stored in access-controlled buckets. No system is perfectly secure, but we take reasonable, industry-standard measures.

Children

MAC Coaching is not directed to children under 13, and we do not knowingly collect their data. Athletes under 18 should use MAC with a parent or guardian's consent.

Changes

If we make meaningful changes to this policy, we'll update this page and note the new date at the top.
