ARETE Fitness Privacy Policy
Last updated: August 17, 2026
Kazuya Yasue, trading as ARETE ("we," "us," or "our") operates the ARETE mobile application ("App"). This Privacy Policy explains how we collect, use, store, and protect your personal information when you use the App.
When you create an account, we collect: your name, email address, date of birth, and gender. This information is used to personalise your experience and manage your account.
To provide the App's core functionality, we collect data you choose to input, including: body weight and weight history; height; fitness goals and experience level; workout logs (exercises, sets, reps, load, rest times); nutrition logs (foods, calories, macronutrients, micronutrients); step count data; training programme progress; equipment settings and preferences.
With your permission, the App may read step count data from Apple HealthKit. This data is used solely to display your step count within the App and is never sold, shared with third parties, or used for advertising purposes. We comply with Apple's HealthKit guidelines and do not store HealthKit data outside of what is necessary to provide the App's step tracking features. You can revoke HealthKit access at any time through your device's Settings > Privacy & Security > Health.
When you use the AI Coach feature, we collect: messages you send to the AI Coach; AI-generated responses; feedback you provide on AI responses (thumbs up/down, tags, notes). Your conversation history is stored to provide context-aware coaching within the App. Your messages are sent to our AI service provider (Anthropic) for processing. We do not use your conversation data for advertising or sell it to third parties.
When you search for foods, the App queries the USDA FoodData Central API and Open Food Facts database. Your search queries are sent to these services to return food data. We do not share your personal information or dietary history with these services — only search terms are transmitted.
We collect anonymised crash reports and performance data through Firebase Crashlytics and Firebase Performance Monitoring to identify and fix technical issues. This data does not include your personal workout or nutrition information.
Subscription payments are processed entirely by Apple through In-App Purchase. We do not collect, store, or have access to your payment card details, billing address, or Apple ID payment information.
We use your information to: provide and personalise the App's features; generate AI Coach responses relevant to your fitness data, goals, and history; calculate nutritional targets (TDEE, macros) based on your profile; track your workout progress and training history; display step count and weight trends; send you notifications you have opted into; identify and fix bugs and improve App performance; comply with legal obligations.
The AI Coach feature processes your data as follows:
When you send a message to the AI Coach, relevant context from your profile is included to provide personalised responses. This context may include: your fitness goals, experience level, recent workout data, recent nutrition data, weight trends, and active programme information. This data is sent to Anthropic's API (Claude) for processing and is subject to Anthropic's data usage policies. We do not use your AI conversations to train AI models. Conversation history is stored in our database (Firebase Firestore) and is deleted when you delete your account.
Your data is stored on Google Firebase (Firestore) servers. We implement industry-standard security measures including: Firebase Authentication for secure account access; Firestore Security Rules that restrict data access to authenticated account owners; encrypted data transmission (HTTPS/TLS); no plain-text storage of passwords (handled by Firebase Authentication).
While we take reasonable measures to protect your data, no method of electronic storage or transmission is 100% secure. We cannot guarantee absolute security.
We do not sell your personal data to third parties. We share data only with the following service providers, solely for the purpose of operating the App:
Google Firebase — data storage, authentication, crash reporting, performance monitoring. Anthropic — AI Coach message processing. Apple — subscription payment processing. USDA FoodData Central and Open Food Facts — food search queries only (no personal data shared).
We may also disclose your information if required by law, legal process, or governmental request.
We retain your data for as long as your account is active. When you delete your account through the App's Profile settings, all your personal data is permanently deleted from our systems, including: account information, workout history, nutrition logs, weight entries, AI conversation history, custom exercises, custom foods, favourites, programme history, and step data. This deletion is immediate and irreversible.
Depending on your location, you may have the following rights regarding your personal data:
Access: You can view all your data within the App at any time. Correction: You can update your profile information, edit workout logs, and modify nutrition entries within the App. Deletion: You can delete your entire account and all associated data through the App's Profile settings. Data Portability: If you wish to receive a copy of your data, contact us at the email below. Withdraw Consent: You can revoke HealthKit permissions through your device settings and stop using AI features at any time.
If you are located in the European Economic Area, you have additional rights under the General Data Protection Regulation, including the right to: access, rectify, or erase your personal data; restrict or object to processing; data portability; lodge a complaint with a supervisory authority. Our legal basis for processing your data is: contract performance (providing the App's services), legitimate interest (improving the App), and consent (HealthKit access, AI Coach usage).
We comply with the New Zealand Privacy Act 2020. You have the right to access and request correction of your personal information. If you believe we have breached the Privacy Act, you may lodge a complaint with the Office of the Privacy Commissioner.
The App is not intended for children under the age of 16. We do not knowingly collect personal information from children under 16. If we become aware that we have collected data from a child under 16, we will delete that information promptly. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.
The App may contain links to third-party websites or services. We are not responsible for the privacy practices of these third parties. We encourage you to review their privacy policies before providing them with any personal information.
We may update this Privacy Policy from time to time. We will notify you of material changes through the App or by other reasonable means. Your continued use of the App after changes take effect constitutes acceptance of the revised policy. The "Last updated" date at the top of this policy indicates when it was last revised.
