Overview
MomGainz uses generative AI (large language models) to power several features. This page explains what model we use, what data we send, how we protect your safety, and the limits of what AI can and cannot do.
Which Features Use AI
- AI Coach chat — conversational answers to training questions.
- AI Workout Generator — produces a structured workout from a free-text prompt.
- AI Program Builder — generates multi-week training programs.
- Weekly recap — summarizes your week's training and suggests focus for the next one.
All other features (Quick Start, Custom Workout builder, Today's Workout auto-pick, Real Life modes, Pelvic Floor, Mobility flow, exercise library, progress tracking) run entirely on your device without AI.
Provider
We use Groq (groq.com), a US-based AI inference provider, to run the large language models that power our AI features. The specific model may change over time as we upgrade to newer or comparable alternatives; the data policies described below apply regardless of the specific model in use.
We may also add secondary AI providers in the future for reliability (failover) or capability reasons. If we do, we will update this page to reflect the current set of providers and what data is sent to each.
What Data Is Sent
Data is only sent when you actively use an AI feature. Nothing is sent in the background, and no AI requests happen at app launch.
Always sent
- The system prompt (describes the coach's persona and safety rules — identical for every request).
- Your typed message, prompt, or the workout parameters you selected.
- Your fitness level ("beginner" / "intermediate" / "advanced"), available equipment preset, and unit preference (lbs or kg).
- Your locale (so the AI responds in English or Spanish).
Sent when relevant
- Up to 5 most-recent completed workouts — template name, date, duration, and exercise names.
- Up to 8 tracked lifts — exercise name, best weight, and last three weights used.
- Postpartum status and weeks postpartum (for workout generator, to filter unsafe exercises).
- Whether you've logged sleep below 5 hours (for intensity scaling).
Never sent
- Your name, email, phone number (we don't collect these in the first place).
- Progress photos or your avatar image.
- Full workout history beyond the summary above.
- Check-in notes, journal entries, body measurements beyond body weight.
- Device identifiers, location, advertising IDs, contact lists, or anything unrelated to training.
What Groq Does with the Data
Per Groq's published policy:
- API requests are not used to train Groq's models.
- API requests are not used to train the underlying models served through Groq.
- Groq may retain request data temporarily (typically up to 30 days) for abuse prevention and operational purposes, after which it is deleted.
The generated response is returned to your device, stored locally in your chat history or workout template, and is not copied back to any server we control.
Safety Guardrails
The AI Coach is built to answer training questions only. We enforce multiple layers of safety filtering and scope restriction on both the client and server sides:
Red-flag input filter
Messages containing markers of potential medical emergencies or injuries (sharp pain, numbness, dizziness, swelling, pop, severe bleeding, pelvic floor symptoms like leakage) are intercepted before reaching the LLM. The user receives a message recommending they consult a medical professional, pelvic floor physical therapist, or their OB-GYN — not AI-generated advice.
Soft-flag hints
Messages with common soreness or stiffness terms still reach the LLM, but the response includes a built-in nudge to prioritize recovery and see a professional if symptoms persist.
Nutrition and supplement scrubbing
The Coach refuses specific macro/calorie numbers and blocks mentions of dosed supplements beyond mainstream items (creatine, whey protein). Pre-workouts, fat burners, and anything requiring dosing guidance are rejected with a redirect to consult a registered dietitian.
Scope guardrails
The system prompt explicitly restricts the Coach to training-only topics. Medical, legal, and psychiatric questions are redirected to qualified professionals.
AI Output Accuracy — Important Limits
Large language models can produce responses that are plausible-sounding but incorrect. MomGainz-generated workouts, Coach answers, and programs:
- Are not medical advice. They are general fitness suggestions.
- Are not a substitute for a qualified personal trainer, physical therapist, doctor, or registered dietitian.
- May contain inaccuracies, especially for edge cases (rare injuries, unusual equipment, medications that affect training).
- Should be evaluated with your own judgment. If an AI suggestion feels wrong for your body, don't follow it.
Postpartum users, users with known diastasis recti, users with chronic conditions, and anyone recovering from injury should consult a pelvic floor physical therapist or physician before acting on AI-generated recommendations.
How to Opt Out
You can use MomGainz without sending any data to any AI provider. The following features are fully on-device and never contact Groq:
- Quick Start workouts (template-based)
- Custom Workout builder
- Today's Workout auto-pick
- Real Life Workouts (At the Park, With Kids, Quick at Home)
- Pelvic Floor kegels session
- Mobility Flow
- Exercise library browsing
- Progress tracking, streaks, achievements
- Sleep logger, protein tracker, weekly check-ins
Simply avoid the AI Coach, AI Workout Generator, Program Builder, and Weekly recap, and no data will be transmitted to Groq.
Changes to AI Providers
If we change AI providers or add new AI features, we will update this page and, where appropriate, prompt you in-app before new data is transmitted.
