Privacy Policy

App: DadGainz Developer: The Yard Apps Contact: [email protected] Effective Date: 2026-04-24

Overview

DadGainz is a local-first fitness app. Your workouts, personal records, photos, and settings live on your device — we do not have accounts, servers, or any place to store your data ourselves.

The one exception is the AI-powered features (AI Coach, AI Workout Generator, Program Builder, and Weekly Check-in). When you use those, a limited slice of your training information is sent to a third-party AI inference provider so it can generate a response. Everything else stays on your device.

This policy explains exactly what gets sent, when, and to whom.

Data Stored on Your Device

All data you enter into DadGainz is stored exclusively on your device using local storage. This includes:

• Workout logs, templates, and exercise history
• Personal records and progression data
• Body weight entries and progress photos
• Check-in history
• Profile info (fitness level, equipment, injuries) and avatar image
• App settings (units, theme, notification preferences)
• AI Coach chat history and saved AI-generated programs

This data:

• Never leaves your device except as described in the "AI Features" section below
• Is not transmitted to The Yard Apps
• Is not backed up to any cloud service we operate
• Is controlled entirely by you

If you delete the app, all locally stored data is removed in accordance with your operating system's standard uninstall behavior. You can also use Settings → Delete All Data to wipe everything inside the app at any time.

AI Features and Data Sent to Third Parties

DadGainz uses a third-party AI inference provider to power its AI features: the AI Coach chat, AI Workout Generator, multi-week Program Builder, and Weekly Check-in recap. The AI inference provider hosts the large language model that generates responses.

When data is sent to our AI provider

Data is sent only when you actively use an AI feature — for example, when you send a message to the AI Coach, ask the app to generate a workout, or open the weekly recap. No AI requests are made in the background.

What is sent to our AI provider

Depending on the feature, the request may include:

• Your message or prompt (e.g. the text you typed to the Coach, or the workout you asked for)
• Training context: your fitness level, available equipment, unit preference (lbs or kg)
• Recent workouts: up to the last 5 completed workouts — template name, date, duration, and exercise names
• Lift progression: up to 8 recent tracked lifts — exercise name, best weight, and the last three weights you used
• Safety context (AI Workout Generator only): a filtered list of exercises deemed safe given injuries you've logged

What is not sent to our AI provider

• Your name, email, phone number, or any contact info (we don't collect these in the first place)
• Progress photos or your avatar image
• Full workout history beyond the recent summary above
• Check-in notes or body measurements not directly relevant to the request
• Device identifiers, location, advertising IDs, or analytics of any kind

What the AI provider does with the data

Per the policies of our AI provider (see this AI Disclosure page), API requests are not used to train their models. The provider may retain request data briefly (typically up to 30 days) for abuse prevention and operational purposes, after which it is deleted. Our AI provider processes the request, returns a response to your device, and the response is stored locally in your chat history or workout template.

How to opt out of AI data transmission

You can use DadGainz without any AI features — the Quick Start workout generator, custom workout builder, exercise library, progress tracking, and all logging features work entirely on-device. Simply don't use the AI Coach, AI Workout Generator, Program Builder, or Weekly Check-in, and no data will be sent to our AI provider.

Analytics, Advertising, Tracking

DadGainz does not include analytics SDKs, advertising networks, or third-party behavioral tracking. We do not know when you open the app, which features you use, or how you navigate. We do not build profiles or sell data.

The only service that receives device-level technical data is Firebase Crashlytics — see the next section.

Crash Reporting (Firebase Crashlytics)

DadGainz uses Firebase Crashlytics (a Google service) to receive automatic reports when the app crashes or encounters a fatal error. These reports help us fix bugs.

What Crashlytics receives:

• Stack trace of the crash (where in our code it happened)
• Device model, OS version, and app version
• A randomly generated installation identifier (not linked to any account or personal identity, since DadGainz has no accounts)
• Time of the crash

What Crashlytics does not receive:

• Your workouts, weights, personal records, photos, or health information
• Your name, email, phone, or any personally identifying information
• The contents of AI Coach chats

Crash reports are retained by Google per Firebase's data retention policies. You can contact us at [email protected] to request deletion of any crash report associated with your device's installation identifier.

Service Providers

Beyond the AI inference provider (described above) and Firebase Crashlytics (crashes, described above), DadGainz relies on these third-party services:

• Google Play (Google LLC) — distributes the app, processes subscription billing, and provides anonymous install/uninstall counts to us via the Play Console dashboard. Google Play's privacy terms apply to billing and distribution.
• Cloudflare, Inc. — hosts ai.dadgainz.com, the small edge service that relays your AI requests to our AI provider. Cloudflare may observe request metadata (IP address, timestamp) transiently for abuse prevention; it does not read or retain the request bodies.

All communication between the app and our servers uses HTTPS/TLS.

Subscription Billing

If you choose to subscribe to DadGainz Premium, payment is processed entirely by Google Play. We do not see or store your credit card, billing address, or any payment details. Google Play gives the app a subscription token so DadGainz can tell whether your account has an active subscription.

To prevent fraud, the subscription token is forwarded once to our Cloudflare Worker at ai.dadgainz.com/verify-purchase, which validates it against Google's official Play Developer API and returns valid: true/false. The token is not stored server-side.

Receipts, refunds, and cancellation are all handled through Google Play at play.google.com/store/account/subscriptions.

No User Accounts

DadGainz does not require or offer user accounts. You do not need to register, sign in, or provide any personal information to use the app.

Health Data Integration (Optional)

If you choose to connect DadGainz to Apple Health (iOS) or Health Connect (Android), the app can read step counts and weight entries to display them inside the app, and write completed workouts so they appear alongside your other activity. This data stays on your device — it is not transmitted to our AI provider, The Yard Apps, or any other third party. You can disconnect at any time via your device's health settings.

Children's Privacy

DadGainz is designed for adult use and is not directed to children under 13. We do not knowingly collect personal information from children. The AI features send limited training data to our AI provider as described above; if you believe a child has used the app, you can wipe all data via Settings → Delete All Data.

Data Security

Because your primary data store is your own device, its security is governed by your device's built-in protections (encryption, screen lock, biometric unlock). Data sent off-device (AI prompts, billing-verification tokens, crash reports) is transmitted over HTTPS/TLS. We recommend you use your device's security features to protect your fitness data.

Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes — particularly if we add, remove, or change third-party data recipients, or introduce new data collection — we will update the effective date above and, where appropriate, provide notice within the app.
