Overview
DadGainz uses generative AI (large language models) to power several features. This page explains what provider 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, Mobility flow, exercise library, progress tracking) run entirely on your device without AI.
Provider
We use one or more third-party AI inference services to run the large language models that power our AI features. Providers are US-based.
We reserve the right to change AI inference providers and models at any time — for reliability, capability, cost, or quality reasons. The data policies on this page describe categories of data we send and how that data may be handled, and remain in effect regardless of which specific provider or model is in use at any given time. If you need the name of the specific provider currently in use for a privacy request or audit, email support@theyardapps.com.
If we ever add a materially different category of provider (for example, an EU-only provider, or a provider with different retention policies), we will reflect that change on this page.
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 your preferred language).
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.
- 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 our AI provider does with the data
Per the policies of our AI provider:
- API requests are not used by the provider to train their AI models.
- The provider 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:
Red-flag input filter
Messages containing markers of potential medical emergencies or injuries (sharp pain, numbness, dizziness, swelling, pop, severe bleeding) are intercepted before reaching the AI. The user receives a message recommending they consult a medical professional — not AI-generated advice.
Soft-flag hints
Messages with common soreness or stiffness terms still reach the AI, 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. DadGainz-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.
Users with chronic conditions or anyone recovering from injury should consult a physician or physical therapist before acting on AI-generated recommendations.
How to Opt Out
You can use DadGainz without sending any data to any AI provider. The following features are fully on-device and never contact any AI provider:
- Quick Start workouts (template-based)
- Custom Workout builder
- Today's Workout auto-pick
- 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 any AI provider.
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.
