1. Who We Are

dynaimic ("we", "us", "our") is operated by Burak Ozaslan and consists of the dynaimic iOS application (the "App") and its backend services (the "Service"). The Service generates personalised, adaptive AI workouts and helps you track strength training over time. This Privacy Policy explains how we collect, use, store, and protect your personal data when you use the App.

For the purposes of the GDPR and Turkish KVKK, dynaimic is the Data Controller.

2. Data We Collect

2.1 Account & Identity

DataPurposeRequired
Apple ID identifier (via Sign in with Apple)AuthenticationYes
Email address (real or Apple Private Relay)Account contact, support repliesYes
Display name (optional, from Apple ID)PersonalisationNo
User ID (UUID)Internal account keyAuto-generated

2.2 Profile & Demographic Data

DataPurposeRequired
GenderWorkout personalisationNo
Date of birthAge-appropriate recommendationsNo
HeightFitness calculationsNo
TimezoneSession scheduling, daily resetNo

2.3 Health & Body Data

Sensitive Data

We collect the following health-related data to provide personalised fitness recommendations:

This data is classified as Special Category data under GDPR Article 9 and KVKK Article 6. We process it only with your explicit consent, provided during onboarding.

2.4 Fitness Profile

DataPurpose
Fitness goal (e.g., muscle gain, fat loss, strength, general fitness)Tailored workout generation
Experience level (beginner, intermediate, advanced)Exercise difficulty matching
Preferred session duration (15–180 minutes)Workout length optimisation
Preferred routine type (PPL, Upper/Lower, Full Body, etc.)Program structure
Available equipment (dumbbells, barbell, cables, etc.)Equipment-appropriate exercises
Selected coach personalityCoach voice and programming style
Unit preferences (metric / imperial)Display formatting

2.5 Workout & Performance Data

2.6 Routine & Program Data

2.7 Subscription & Purchase Data

Subscription status, purchase history, renewal dates, and free-trial state. We never see your payment card or banking details — those are handled exclusively by Apple. We receive only a signed receipt from Apple confirming the purchase, which is passed to RevenueCat for cross-device subscription state.

2.8 Diagnostics & Performance (Pseudonymised)

To find and fix bugs, the App sends crash reports and performance traces to Sentry. Before sending, your user identifier is hashed with a salted one-way function so the diagnostic record cannot be re-linked to your account. We do not send your name, email, IP address, or any user-typed content to Sentry.

2.9 In-App Analytics (Pseudonymised)

Screen views and basic feature interactions are recorded to understand which parts of the app help users and which don't. Analytics events use the same salted hash as diagnostics — they are not linked to your real identity.

We do not sell your data. We do not share your data with advertisers or data brokers. We do not use your data to build cross-app or cross-company profiles.

4. Sub-Processors & Third-Party Sharing

Important

To run the Service, we rely on a small number of trusted third-party providers. Each receives only the data they need to perform their function and is bound by their own privacy commitments.

4.1 Apple

Sign in with Apple is the sole authentication mechanism for dynaimic. Apple processes your Apple ID identity token to authenticate you. The App Store handles all subscription billing and payment information. Push notifications (if you opt in) and optional Apple Health integration are also Apple services.

Apple's privacy policy: apple.com/legal/privacy.

4.2 Supabase (authentication & database)

We use Supabase for user authentication via Sign in with Apple flows, and to store account data, profile information, workouts, routines, and measurements. Supabase acts as a Data Processor on our behalf.

Supabase privacy policy: supabase.com/privacy.

4.3 RevenueCat (subscription management)

RevenueCat manages your subscription state, free-trial status, and purchase restoration across devices. RevenueCat receives your user identifier and Apple-issued purchase receipts. Payment details never reach RevenueCat or us — only Apple's signed receipts.

RevenueCat privacy policy: revenuecat.com/privacy.

4.4 Sentry (diagnostics)

Sentry receives crash reports and performance traces. We send a salted SHA hash of your user identifier — not your email, name, IP address, or any free-text content you have entered. This allows multiple crashes from the same account to be grouped for triage without re-identifying you.

Sentry privacy policy: sentry.io/privacy.

4.5 AI inference providers (OpenAI)

When you request a workout, parts of your fitness profile, training history, and "How did it feel?" feedback are sent through OpenAI's API to generate the session. We use the API tier that does not use your inputs to train OpenAI's public models. OpenAI may retain API inputs and outputs for up to 30 days for abuse monitoring before deletion.

Data sent per generation request includes: your fitness profile, your last 5 body weight / body fat measurements with trend direction, your last 15 workout sessions with set-level detail, your top 5 personal records, recent session feedback, training-frequency metrics, the selected coach personality, the active routine context, and up to 25 candidate exercises from our catalogue. We do not send your name, email, or payment information to OpenAI.

OpenAI's data usage policy: openai.com/policies/api-data-usage-policies.

4.6 Legal disclosures

We may disclose information if required by law, court order, or governmental request, or if necessary to protect the rights, property, or safety of dynaimic, our users, or the public. When permitted, we will notify you before doing so.

5. Apple HealthKit Data

If you grant dynaimic permission to read from or write to Apple Health, the following specific rules apply:

These restrictions are required by Apple's HealthKit rules and we follow them strictly.

Under GDPR and KVKK, we process your personal data on the following legal grounds:

7. Data Retention

Profile & fitness preferencesUntil account deletion
Body measurementsUntil account deletion or manual removal
Workout sessions & exercise logsUntil account deletion
Routine data & progressUntil account deletion
Session ratings & feedbackUntil account deletion

When you delete your account, all personal data associated with your account is permanently removed from our active systems within 30 days, except where we are legally required to retain certain records.

8. Data Security

We implement industry-standard technical and organisational measures to protect your data:

No system is perfectly secure, but we take reasonable steps to prevent unauthorised access, alteration, or disclosure. If we ever experience a personal data breach that affects you, we will notify you and the relevant supervisory authorities as required by applicable law.

9. Your Rights

Under GDPR, KVKK, and other applicable data-protection laws, you have the following rights:

To exercise any of these rights, email support@dynaimicpt.com from the email associated with your account. We will respond within 30 days.

10. Deleting Your Account

You can delete your account at any time from inside the App:

  1. Open the Profile tab
  2. Go to Settings → Account
  3. Tap Delete Account and confirm

Deleting your account permanently removes your workout history, custom routines, measurements, profile data, and personal records from our active systems within 30 days. This action cannot be undone.

Deleting your dynaimic account does not automatically cancel any active App Store subscription — you must cancel that separately via iPhone Settings → Apple ID → Subscriptions.

If you cannot access the in-app deletion flow, email support@dynaimicpt.com from your account email and we will process the deletion manually within 7 days.

11. Children's Privacy

dynaimic is rated 9+ on the App Store but is designed for use by individuals aged 16 or older (or 13 or older where local law permits, with parental involvement). We do not knowingly collect personal data from children under 13. If you believe a child has provided us with personal data, please contact us at support@dynaimicpt.com and we will delete it promptly.

12. International Data Transfers

Your data may be transferred to and processed in countries outside your country of residence, including:

For transfers from the EU/EEA or Türkiye, we rely on appropriate safeguards including Standard Contractual Clauses (SCCs) and each sub-processor's data-processing commitments. See the Data Processing Agreement for the full sub-processor list and transfer mechanisms.

13. Cookies & Tracking

The dynaimic mobile application does not use cookies, web beacons, or browser-based tracking technologies. The App communicates with our backend via authenticated HTTPS requests. We do not integrate advertising trackers, and dynaimic does not request the App Tracking Transparency (ATT) permission because we do not engage in cross-app or cross-website tracking.

14. Changes to This Policy

We may update this Privacy Policy from time to time. When we make a material change, we will increment the version number, update the effective date at the top of this page, and notify you inside the App the next time you open it. Continued use of the Service after a change takes effect constitutes acceptance of the updated policy. If you do not agree to an update, you may delete your account.
