Last updated: August 15, 2026

This Privacy Policy describes how Fitfo: Workout AI Planner & Log (“we”, “us”, or “our”) collects, uses, and protects information when you use our mobile application (“App”). We are committed to protecting your personal fitness data and your privacy.

Information We Collect

Fitfo collects information that you voluntarily provide to plan and track your workouts:

  • Profile information: Name, age, gender, height, and weight
  • Fitness goals & preferences: Training objectives, experience level, available equipment, and weekly schedule
  • Workout logs: Exercises performed, sets, reps, weights, duration, and personal records
  • Body metrics: Body weight, body fat percentage, and other measurements you choose to track
  • Account information: Email address (if you choose to create an account via Apple Sign-In or email)

How We Use Your Data

Your data is used solely to provide and improve the App's functionality:

  • Generate personalized AI workout plans tailored to your goals, fitness level, and schedule
  • Track your workout history, progress, and personal records over time
  • Provide insights and analytics on your training performance and trends
  • Sync data across your devices when you sign in with an account
  • Continuously improve AI plan generation based on your logged results

Data Storage

Fitfo stores your workout data locally on your device by default. If you choose to create an account, your data is securely synced to our cloud servers (powered by Supabase) to enable cross-device access. All data transmitted between your device and our servers is encrypted using industry-standard TLS encryption.

Data Retention

We retain your data only for as long as it is needed to provide the App's features to you:

  • Account and workout data: Retained for as long as your account remains active. If you delete your account, all associated profile information, workout logs, plans, and body metrics are permanently deleted from our servers within 30 days.
  • Locally stored data: If you use the App without an account, your data stays on your device and is retained until you delete it in the App or uninstall the App.
  • Individual records: Workout logs, plans, and metrics you delete within the App are removed from our servers within 30 days.
  • Inactive accounts: If an account remains inactive for 24 consecutive months, we may delete it and its associated data after notifying you at your registered email address.
  • AI plan generation data: Information sent to third-party AI providers to generate your workout plans is processed only to return your plan and is not retained by us beyond storing the generated plan in your account.
  • Backups and logs: Residual copies in encrypted backups and diagnostic logs are purged on a rolling basis and are fully removed within 90 days of deletion.
  • Legal obligations: We may retain limited information for longer where required to comply with legal obligations, resolve disputes, or enforce our agreements.

AI Workout Planner

Our AI-powered workout planner uses your profile information, fitness goals, and training history to generate personalized workout plans. Plan generation may be processed by third-party AI providers. We do not use your personal data to train AI models. The AI planner provides fitness guidance only and is not a substitute for advice from a qualified personal trainer or healthcare professional.

Third-Party Services

We use the following third-party services:

  • Supabase: For secure authentication and cloud data storage
  • Apple Sign-In: For optional account authentication
  • AI providers: For powering the AI workout plan generation feature

We do not integrate advertising SDKs or sell your data to any third parties.

Data Sharing

We do not sell, rent, or share your personal information with third parties for marketing purposes. Your fitness data is private and is never shared without your explicit consent.

Your Rights & Data Deletion

You have full control over your data:

  • You can delete individual workout logs, plans, and metrics at any time within the App
  • You can delete your entire account and all associated data from the Settings screen
  • You can export your workout history by contacting us directly

Security
