This Privacy Policy describes how the mobile application Fitence: Workout Planner, developed by Core Helper Lab ("Developer", "we", "us"), collects, uses, and protects user information. By using the App, you agree to this Privacy Policy.
Data Storage Modes
1.1 Use Without an Account
By default, the App can be used without registration. In this mode:
- workout data, progress, and settings are stored locally on your device;
- the Developer does not process this data on its servers and does not have direct access to it.
1.2 Use With an Account (Google / Apple ID)
If you connect an account:
- your data is synced via Firebase (Google LLC);
- a unique user identifier (UID) is used;
- data is used only for backup and synchronization across devices.
Access to this data is restricted to you as the authenticated user.
1.3 Health and Fitness Data
The App collects workout-related data including exercise names, sets, repetitions, weight, duration, and training history. This data is classified as health and fitness data.
- Without an account — stored locally on your device only;
- With an account — synced via Firebase for backup and cross-device access.
This data is used solely to provide App functionality and is never sold or shared with third parties for advertising purposes. If you choose to use the optional AI-powered workout analysis, the relevant workout and profile data described in Section 4.5 is shared with our AI provider (Anthropic) only after you give explicit in-app consent. See Section 4.5 for details.
Personal Data
To provide you with a seamless experience, we collect specific categories of data through your use of the app and third-party integrations. We prioritize your privacy by strictly limiting the data we access.
2.1 Types of Data Collected
We gather the following information to ensure app functionality, performance, and personalization:
- Authentication Data: We receive your display name, email address, and provider identifier when you sign in via Google or Apple.
- Health & Fitness Data: We process your workout history, exercise data, and body metrics such as weight, height, and date of birth. With your explicit in-app consent, a subset of this data is shared with our AI provider (Anthropic) to generate workout analysis — see Section 4.5.
- App Activity: We track in-app events and feature usage via Firebase Analytics and Mixpanel to improve our services. A pseudonymous device identifier (Firebase App Instance ID) is used — no name, email, or other personal data is associated with analytics.
- App Info & Performance: We collect crash logs and diagnostic data through Firebase Crashlytics to maintain app stability.
- Device Identifiers: With your explicit consent, we may use your Advertising ID / IDFA for AdMob.
- Purchase History: We track subscription and purchase status through RevenueCat to manage your access to premium features.
2.2 Data We Do NOT Collect
We believe in data minimization. Consequently, we do not access, collect, or store the following sensitive information:
- Financial Security: We never collect passwords or payment card details.
- Privacy-Sensitive Hardware: We do not access your camera, photos, or microphone.
- Personal Privacy: We do not collect your contacts or your precise GPS location.
All data collection for advertising purposes (IDFA) is strictly opt-in. We only process this information if you provide explicit permission via your device settings.
Legal Basis for Processing
We process data based on:
- Contract performance — to provide App functionality;
- Legitimate interests — analytics, improvement, stability;
- User consent — where required (e.g., personalized ads; sharing workout and profile data with our AI provider for AI analysis).

4.5 Anthropic (AI Workout Analysis)
The App offers an optional AI-powered analysis of your completed workouts. This feature is provided using the AI models of Anthropic, PBC ("Anthropic"). The request is routed through our secure Firebase Cloud Function (which holds the API credentials) to the Anthropic API.
This feature is strictly opt-in. No data is sent to Anthropic until you tap to request an analysis and grant explicit consent on the in-app disclosure screen shown before the first request.
When you request an analysis, the following data is sent for that single request:
- Profile data: sex, age, height, weight, calculated BMI, and training goal;
- Workout data: workout name, date, planned and actual duration, and per-exercise details (sets, repetitions, weights, durations, and volumes).
We do not send your name, email address, account identifier, precise location, or any payment information to Anthropic.
The data is used only to generate your workout analysis. Under Anthropic's commercial terms, your inputs and outputs are not used to train Anthropic's models and are not used for advertising. Anthropic processes the data as our service provider and provides a level of data protection equivalent to that described in this Policy, including contractual data-protection commitments and Standard Contractual Clauses for international transfers (see Section 8).
You can decline at the consent screen; declining means no data is shared and the AI analysis is not generated. Anthropic Privacy Policy: anthropic.com/legal/privacy
Advertising
The App uses Google AdMob in the free version. It may use:
- Advertising ID (Android) / IDFA (iOS);
- anonymized behavioral data.

Users who do not consent will receive non-personalized ads only. Consent can be withdrawn or changed at any time via App Settings → Privacy.
Depending on device settings and applicable laws (e.g., GDPR), users may be shown non-personalized ads.
Ads can be disabled via an in-app purchase or Premium subscription.
