Privacy Policy
Last updated: July 17, 2026
Only Fitness (the “app”) is an AI-powered personal fitness coaching application operated by Solarity AI (“we”, “us”, “our”). This Privacy Policy explains what information we collect, why we collect it, how it is used and shared, how long it is kept, and the rights and choices you have. By creating an account or using the app, you agree to the practices described here.
1. Data we collect
- Account information:your email address and authentication identifiers. When you sign in with Apple or Google, we receive the identifier those providers return; if you use “Hide My Email” with Apple, we receive only the relay address.
- Profile information: sex (used as a calculation parameter for energy needs), age, height, weight, your training goal (bulk, cut, or maintain) and target, sleep routine, and any optional body metrics (such as body-fat percentage or muscle mass) you choose to provide.
- Meal information: photos of meals you submit for analysis and any text descriptions or corrections you add. See Section 4 for how meal photos are handled.
- Body-transformation photos: photos you upload for the before/after body-comparison feature. Unlike meal photos, these are stored (see Section 4).
- Training, sleep, and weight logs: descriptions of your workouts (typed or spoken), reported sleep, and weight or body-metric entries you log over time, together with the coaching analysis and reports generated from them.
- Voice input: if you describe training or meals by voice, the audio is transcribed to text for analysis and is not retained after transcription.
- Subscription and entitlement data: your subscription status, trial status, and any promo-code entitlement, synced from our payments provider. We do not receive or store your payment-card details.
- Technical and usage data: basic device and diagnostic information (such as app version, device type, and crash logs) needed to operate, secure, and troubleshoot the app.
2. Health and fitness data
Much of the information above (your body metrics, meals, training, sleep, weight, and body photos) relates to your health and fitness and may be considered sensitive or special-category data. We process it onlyto provide the app’s coaching features to you. We do not use health or fitness data for advertising, and we do not sell it or share it with data brokers. Where the law requires it, we rely on your consent, which you give by choosing to provide this information and which you can withdraw at any time by deleting the relevant data or your account.
3. How we use your data
- To analyze your meals, training, and sleep and generate your personalized daily, weekly, and monthly coaching reports.
- To produce body-transformation comparisons from the photos you upload for that feature.
- To maintain your profile, streaks, and history so your reports are evaluated against your stated goal over time.
- To manage your account, subscription, trial, and any promo-code entitlement.
- To secure the service, prevent abuse, enforce usage limits, and diagnose technical problems.
- To comply with our legal obligations.
4. How we handle photos
We treat the two kinds of photos differently, by design:
- Meal photos are not stored. When you photograph a meal, the image is sent to our AI provider for analysis and is discarded once the nutritional analysis is returned. We do not keep meal photos on our servers.
- Body-transformation photos are stored, because the comparison feature depends on comparing images over time. They are stored securely in our storage provider and remain until you delete them or delete your account. You control when these photos are added, and you can remove them at any time.
We do not use your photos to train AI models.
5. How we use AI
We use OpenAI as our third-party AI provider to analyze the food, training, sleep, and body-comparison information you submit and to generate your coaching reports. The inputs you provide are sent to OpenAI solely to produce that analysis for you. Under our agreement and OpenAI’s API terms, this data is not used to train their models. AI- generated coaching content can be imperfect or inaccurate and is provided for guidance only (see Section 11).
6. Who we share data with
We do not sell your personal data. We share it only with the service providers necessary to operate the app, each bound by contractual and legal obligations to protect it and to use it only to provide services to us:
- OpenAI — AI analysis and report generation, and voice transcription.
- Supabase — database, authentication, and secure storage of your account data and body photos.
- RevenueCat — subscription and entitlement management.
- Apple App Store / Google Play — sign-in (where you choose it) and processing of subscription payments.
We may also disclose information if required by law, to protect our rights or the safety of others, or in connection with a business transfer, in which case we will continue to protect your data as described here.
7. International data transfers
We and our service providers may process your data in countries other than the one you live in, including the United States. Where required, we rely on appropriate safeguards for these transfers, such as the European Union Standard Contractual Clauses.
8. Data retention
We keep your profile, logs, reports, and stored body photos for as long as your account is active, so that your coaching history remains available to you. Meal photos are not retained (Section 4). When you delete specific entries they are removed, and when you delete your account we delete your associated personal data, except where we are required to retain limited records to meet legal, tax, or security obligations.
9. Your rights and choices
Depending on where you live, you may have the right to access, correct, export, restrict or object to the processing of, and delete your personal data, and to withdraw consent. We honor these rights regardless of location. In particular:
- In-app account deletion: the app includes an option to delete your account, which removes your profile, logs, and stored body photos.
- You can edit or delete individual entries and photos at any time from within the app.
- You can contact us at ata.turhan@solarityai.com to exercise any of these rights.
We comply with applicable data-protection laws including the EU/UK GDPR, the California Consumer Privacy Act (CCPA/CPRA), and Turkey’s Law on the Protection of Personal Data (KVKK). We do not sell or “share” personal information as those terms are defined under California law.
10. Data security
We use administrative and technical measures, including encryption in transit and access controls, to protect your data. Each user can access only their own data. No method of transmission or storage is completely secure, but we work to protect your information and to limit access to it.
11. Not medical advice
Only Fitness is a coaching and fitness-tracking tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before beginning a new exercise program or making significant changes to your diet, especially if you have a pre-existing medical condition.
12. Children’s privacy
The app is not directed to children under 13 (or the minimum age of digital consent in your country), and we do not knowingly collect personal data from them. If you believe a child has provided us with personal data, please contact us and we will delete it.
13. Changes to this policy
We may update this Privacy Policy from time to time. When we make material changes, we will update the “Last updated” date above and, where appropriate, notify you in the app. Your continued use of the app after an update takes effect constitutes acceptance of the revised policy.
14. Contact
Questions or requests regarding this policy or your data can be sent to ata.turhan@solarityai.com.
