Privacy Policy
Last updated: 24 May 2026
This Privacy Policy explains how Mukac Studio ("we", "Fcoach") collects, uses, and protects your personal data when you use the Fcoach mobile application (the "App"). By using the App, you agree to this policy.
1. Data We Collect
a) Account Information
- Name and email address (via email/password, Google, or Apple sign-up)
- If you use Sign in with Apple, the identity information Apple provides (which may include a private relay email)
b) Profile & Fitness Data
- Your age, height, weight, and training goals
- Workout programs you create, exercise logs, personal records (PRs), and set/rep data
- Statistics: streak, total workouts, XP, and progress
c) Activity / Motion Data
- Step count from your device's motion sensor (pedometer) and the estimated calories derived from it
- This data is processed on your device; your step history is used to power the app experience
d) AI Coach Data
- Messages you send to the AI Coach and your program creation/editing requests
- This content is sent to our AI service providers to generate responses (see Section 4)
e) Subscription Status
- Your Pro subscription status (active/inactive)
f) Notifications
- Notification permission for local notifications such as rest timers (runs only on your device)
2. How We Use Your Data
- To create and manage your account
- To deliver personalized workout programs and provide the AI Coach feature
- To show your progress, streaks, and statistics
- To track steps and activity
- To improve the App, fix bugs, and prevent abuse (usage limits)
- To meet our legal obligations
3. Legal Basis
We process your data on the basis of contract performance (providing the service), your explicit consent (motion data, notifications), and our legitimate interests (security, improvement). Your rights under GDPR and KVKK are described in Section 7.
4. Third-Party Services
We use the following providers to deliver the service:
- Google Firebase (Authentication, Firestore, Cloud Functions) — account, data storage, and server operations. Data is hosted on Google infrastructure.
- AI providers (Google Gemini and DeepSeek) — your AI Coach messages and program creation/editing requests are sent to one of these providers to generate a response, depending on which model is handling your request. This content is sent solely to produce a response and is not used by these providers to train their models.
- Apple and Google — "Sign in with" authentication services
These providers' own privacy policies apply. Due to the nature of the service, data may be processed on servers located abroad. Google: policies.google.com/privacy · DeepSeek: deepseek.com/privacy-policy · Apple: apple.com/legal/privacy
5. Data Retention
We retain your data for as long as your account is active. When you delete your account (see Section 8), all of your personal data is permanently deleted.
To prevent abuse of free usage limits (for example, deleting and recreating an account to reset daily quotas), we keep one small residual record after deletion: an irreversible cryptographic hash of your email address together with your remaining usage-quota counters. This hash cannot be reversed to recover your email address, contains no other personal data, and is used only to apply your existing quota if the same email address registers again.
6. Data Security
Your data is transmitted over encrypted connections (HTTPS) and stored on Firebase infrastructure protected by authorized access only. While no method is 100% secure, we take reasonable technical and administrative measures to protect your data.
7. Your Rights
Under GDPR and KVKK, you have the right to:
- Access your data and request a copy
- Correct and update it
- Request its deletion
- Object to processing or withdraw your consent
To exercise these rights, contact us at contact@fcoach.net.
8. Account & Data Deletion
You can permanently delete your account and all of your data (programs, statistics, progress, account information) from within the App via Profile > Delete Account. This action cannot be undone. Alternatively, you can request deletion by emailing contact@fcoach.net.
9. Children's Privacy
Fcoach is not intended for children under 13. We do not knowingly collect data from users under 13. If we discover such data, we will delete it.
10. Changes to This Policy
We may update this policy from time to time. For significant changes, we will notify you through the App or our website. The "Last updated" date reflects the latest changes.
