Privacy Policy
Effective Date: April 10, 2026
This Privacy Policy describes how OneR Apps ("we," "us," or "our") collects, uses, and shares information when you use the Dayo — Country Tracker mobile application (the "App"). By using the App, you agree to the practices described below.
1. Information We Collect
On-Device Data Only
The App is designed to keep your data fully on-device. The following information is stored locally and is NOT transmitted to our servers:
- Visits and travel history — countries, dates, notes, and source (manual, photo import, or auto-tracking)
- Passport selection — an optional ISO country code for Schengen calculator personalization
- Auto-tracking preference — on/off setting
Information Accessed with Your Permission
- Location data (when Auto-Tracking is enabled) — We access your device's location in foreground and background to detect country crossings. Country matching is performed locally on your device. We do not transmit raw GPS coordinates to our servers.
- Photo library (when you use Photo Import) — We read each photo's date and EXIF location to reconstruct travel history. Photos themselves never leave your device. Geocoding of coordinates to country codes is performed via Apple's CLGeocoder service on your device.
Third-Party Services
- Firebase Analytics (Google) — Collects anonymous, aggregate usage data (app opens, screen views, feature interactions, device model, OS version, country, randomly generated installation ID). Does NOT include your name, email, location, visits, or personally identifiable information.
- RevenueCat — When you start, restore, or cancel a subscription, RevenueCat receives a randomly generated user ID, your subscription product, and entitlement status. Does not receive your Apple ID, name, or email.
- Apple Crash Diagnostics — If you enabled "Share With App Developers" in iOS settings, Apple may send anonymized crash logs to us.
2. How We Use Information
We use the information described above to:
- Provide the App's core features (visit tracking, statistics, reports, achievements, Schengen calculator, photo import, auto-tracking)
- Process and validate premium subscription purchases
- Diagnose crashes, improve performance, and understand feature usage
We do NOT:
- Sell your information
- Use your information for advertising
- Build behavioral profiles about you
3. How We Share Information
We share information only with the following service providers:
| Provider | Purpose |
|---|---|
| Apple | App distribution, in-app purchases |
| Google (Firebase) | Anonymous analytics |
| RevenueCat | Subscription management |
We do not share your travel history, passport selection, location data, or photos with anyone.
4. Data Retention
- On-device data — Retained until you delete the App or clear it from within the App
- Analytics data — Retained by Google for 14 months, then deleted
- Subscription records — Retained by RevenueCat as required by law
5. Your Rights
You can exercise most data rights directly in the App by editing or deleting visits, or by uninstalling the App. For requests related to analytics or subscription data, contact us at support@onerapps.com
6. Children's Privacy
The App is not directed to children under 13. We do not knowingly collect personal information from children.
7. Security
We use industry-standard practices to protect your data, including HTTPS/TLS in transit, on-device encryption (provided by iOS), and minimum data collection.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be announced through the App.
