Privacy policy

Cristian Rus (“we”, “us”, or “our”) operates the ftnss mobile application (the “Service”). This policy describes what information the Service may collect, how we collect it, how we use it, who we share it with, and the choices you have.

Summary

The Service runs primarily on your device. We do not operate our own servers to store your full health history for browsing by us. To power AI features you enable, limited content may be transmitted to Google Gemini for processing. Purchase verification may be handled by RevenueCat. Below we identify categories of data, collection methods, purposes, and each third party, including links to their privacy terms.

What data the app may collect or process

Depending on what you enter and which permissions you grant, the Service may process:

How we collect data

How we use data

AI health recommendations. ftnss may use Google Gemini to generate fitness, nutrition, and sleep recommendations from your data. All such responses are produced by an AI model for general wellness only. They are not medical advice, diagnosis, or treatment. Accuracy depends on your data and the limits of AI. Consult a qualified healthcare professional for medical decisions.

Sharing and third parties

We do not sell your personal information. We share data only as needed to provide the Service with the following partners:

Google Gemini (Google LLC)

What is shared: When you use cloud AI features with Gemini, the app may send prompts and permitted contextual data described above so Google can return generated content. Google processes this under its own infrastructure.

Purpose: Generating personalized workout, nutrition, sleep, and recovery insights and answering your AI requests.

Protection: Google’s handling of data sent to Gemini is governed by Google’s privacy policy and terms for its AI services. We rely on Google’s published commitments for consumers and developers; you should review them to understand retention, security, and regional terms that apply to you.

Google AI terms and privacy information

RevenueCat

What is shared: Purchase and subscription validation data (such as app user identifiers and transaction metadata as implemented by RevenueCat) needed to confirm entitlement and restore access.

Purpose: Verify purchases, manage subscription status, and restore purchases if you reinstall the app.

Protection: RevenueCat provides subscription infrastructure under its privacy policy and security practices. We use RevenueCat so purchase handling meets industry-standard safeguards appropriate for payment-adjacent data.

Apple

Apple provides the operating system, App Store, Apple Health, and (where available) on-device or Private Cloud Compute features. Apple’s handling of your Apple ID, Health data, and purchases is described in Apple’s own privacy materials. Where you use Apple Intelligence features that stay on device or use Apple’s private cloud path, Apple’s terms apply; some analyses may still route through Gemini when you choose that provider or when a feature requires it.

How each permission is used

Your control

You choose which permissions to grant in iOS Settings. If you do not want a category of data used for AI personalization, do not grant that permission, remove that data from the app, or disable the related feature.

You can switch the AI provider in the app’s settings where offered. Using Gemini means permitted data may be processed by Google as described above. Apple Intelligence may remain local or use Apple’s private cloud when available, but some features (such as certain photo or barcode analysis) may still require Gemini depending on your configuration and device capabilities.

Retention

Data stored on your device remains until you delete the app or erase it in Health or app settings. Data processed by Google or RevenueCat is retained according to their respective policies and what is required to operate the Service. We do not maintain a separate user database on our own servers for the full contents described in this policy.
