Privacy Policy
BetterWalk ("the App") is published by Lina Studio Yazilim Reklam Teknolojileri Arastirma Gelistirme ve Pazarlama Ticaret A.S., trading as NativeMinds ("we", "us"), İçerenköy Mah. Topçu İbrahim Sk. Quick Tower Sit. No:8-10D, Ataşehir / İstanbul, Türkiye . We are the data controller. Contact: info@betterwalk.app (privacy and support).
1. Data we collect
- Onboarding quiz: goal, age, height, weight, target weight, activity level and constraints (e.g. joint issues). Stored on your device and used to personalise your walking plan.
- Health data (Apple HealthKit / Android Health Connect), only after you grant permission: steps, distance, active energy, weight and workouts. We read this to show progress and may write walks and weight entries you log.
- Friend challenges (optional): display name, a Firebase account ID (anonymous, or Sign in with Apple / Google — which may provide an email address), and step totals for the challenge, stored in Google Firebase (Firestore, Authentication).
- Analytics & crash data: pseudonymous usage events, device model, OS version, app version, crash logs and an app-instance identifier via Firebase Analytics and Crashlytics. These do not contain your health data.
- Purchases: subscription status and an anonymous app user ID via RevenueCat. Payments are processed by Apple or Google; we never receive your card details.
2. Health data (HealthKit & Health Connect)
- Health data is accessed only with your explicit permission, which you can revoke at any time in iOS Settings › Health › Data Access, or in Android Health Connect settings.
- It is stored on your device. It is not uploaded to our servers, except that the step totals you choose to include in a friend challenge are synced to Firebase.
- We do not sell health data, use it for advertising, marketing or data mining, or share it with third parties except as needed to provide the features you use (e.g. challenge totals), or where required by law.
- We do not store health data in iCloud. Health data is not used for any purpose other than providing and improving health and fitness features of the App.
- Android: the App's use of information received from Health Connect adheres to the Health Connect Permissions policy, including the Limited Use requirements.
3. How and why we use data (legal bases)
| Purpose | Legal basis (GDPR / KVKK) |
|---|---|
| Personalised plan, progress tracking | Contract; explicit consent for health data (GDPR Art. 9(2)(a); KVKK Art. 6) |
| Friend challenges | Consent / contract |
| Analytics, crash reporting, app stability | Legitimate interests or consent where required |
| Subscriptions | Contract; legal obligations |
4. Sharing & processors
We use service providers acting on our behalf: Google Firebase (Firestore, Auth, Analytics, Crashlytics), RevenueCat (subscription management), Apple and Google (app stores, sign-in, payments). We do not sell or "share" (CCPA sense) personal information, and we do not use it for cross-context behavioural advertising.
5. International transfers
Processors may process data outside your country (e.g. USA). Transfers rely on Standard Contractual Clauses or other lawful mechanisms; for Turkey, KVKK Art. 9 transfer rules apply (see our KVKK Information Notice / Aydınlatma Metni).
6. Retention
On-device data remains until you delete it or uninstall the App. Challenge data is kept while your account is active and deleted within 30 days of account deletion. Crashlytics/Analytics data is retained per Firebase defaults (e.g. up to 14 months for Analytics, 90 days for crashes).
7. Account & data deletion
- In the App: Settings › Account › Delete account. This deletes your Firebase account and challenge data and clears local data.
- By email: write to info@betterwalk.app with subject "Delete my data" — we respond within 30 days.
- Deleting the App removes on-device data. Data already written to Apple Health / Health Connect is managed in those apps.
- Deleting your account does not cancel a subscription — cancel in App Store / Google Play.
8. Your rights
GDPR/UK GDPR: access, rectification, erasure, restriction, portability, objection, withdrawal of consent, and complaint to your supervisory authority. KVKK (Turkey, Art. 11): learn whether data is processed, request information, correction, deletion, objection, and compensation; you may apply to the KVKK Board. CCPA/CPRA (California): right to know, delete, correct, opt out of sale/sharing (we do neither), limit use of sensitive personal information (we use it only to provide the service), and non-discrimination. Contact us to exercise any right; we may verify your identity.
9. Children
BetterWalk is intended for users aged 16 and over. We do not knowingly collect data from children under 16; contact us and we will delete it.
10. Security
Data in transit is encrypted (TLS); Firebase data is protected by access rules. No method is 100% secure.
11. Notifications
Reminders are local notifications scheduled on your device; no push-token-based marketing is used. You can disable them in your device settings.
12. Changes
We will post updates here and update the effective date; material changes will be notified in the App.
