# Privacy Policy — Schengen Calculator **Last Updated:** July 15, 2026 This Privacy Policy describes how the Schengen Calculator mobile application (the "Application") handles information. The Application is provided by NEXTLINE YAZILIM LİMİTED ŞİRKETİ (the "Service Provider") as a commercial service. By using the Application, you agree to the practices described in this Policy. --- ## Summary The Schengen Calculator is a **fully offline, on-device** tool. It helps non-EU travelers calculate their Schengen 90/180-day allowance. **Your trips, travel dates, traveller details, and passport/flag information never leave your device.** There are no accounts, no login, and no servers that store your travel data. The only information that may ever leave your device is **anonymous, non-personal** diagnostic and usage data collected by third-party SDKs (analytics and crash reporting), and **subscription/purchase status** processed by our payments provider. None of this includes your trips or identity. --- ## Information You Enter (Stored On-Device Only) To calculate your Schengen allowance, the Application lets you enter and save data such as: - Trip entry and exit dates - Traveller labels or names you choose - Passport / flag selections and settings - App preferences (theme, reminders, and similar options) All of this information is stored **locally on your device** using an on-device database (Hive). It is **never transmitted to us or to any server**, and we cannot access it. This data remains on your device until you delete it or uninstall the Application. The Application performs all calculations (current status, "leave by" date, maximum future stay, and the rolling-window analysis) **entirely on your device**. No calculation requires an internet connection or a remote server. --- ## Information Collected Automatically (Anonymous) The Application integrates third-party SDKs that may collect **anonymous, non-personal** technical information to help us understand app performance and improve the product. This may include: - **Device and app information** — device model, operating system version, app version, language, and general region. - **Usage events** — anonymous, aggregated interactions such as which screens are opened or which features are used. - **Crash diagnostics** — anonymous crash logs and technical error reports used to diagnose and fix problems. This automatically collected information is **pseudonymous** and is **not linked to your identity**. It **never includes** your trips, travel dates, traveller names, passport/flag data, or any content you enter into the Application. --- ## Location The Application does **not** collect, request, or track the location of your device. It does not use GPS or any location services. --- ## Device Permissions - **Notifications (optional):** With your permission, the Application can schedule **local reminder notifications** on your device (for example, reminders related to your allowance). These reminders are generated and delivered **entirely on your device**. There is no push server, and no notification content is sent to us. You can disable notifications at any time in your device settings. The Application does not request access to the camera, microphone, photo library, contacts, or location. --- ## Third-Party Services The Application uses the following third-party services. Each processes only the limited, non-personal information described above and operates under its own privacy policy: | Service | Purpose | Data Involved | |--------|---------|---------------| | **RevenueCat** | Processes and validates in-app subscriptions and restores purchases | Purchase/subscription status, pseudonymous app-install identifier, and platform receipt data | | **Amplitude** | Anonymous product usage analytics | Anonymous usage events, device/app metadata | | **Firebase (Crashlytics / Analytics for Firebase)** | Crash diagnostics and anonymous app performance/usage analytics | Anonymous crash logs, device/app metadata | Purchases themselves are handled by the **Apple App Store** or **Google Play Store** according to their respective terms and privacy policies. We do not receive or store your payment card details. We encourage you to review the privacy policies of these providers: - RevenueCat — https://www.revenuecat.com/privacy - Amplitude — https://amplitude.com/privacy - Firebase / Google — https://firebase.google.com/support/privacy --- ## What We Do NOT Do - We do **not** operate accounts, logins, or user profiles. - We do **not** store your trips, dates, or traveller data on any server. - We do **not** sell or rent your personal information. - We do **not** track your location. - We do **not** access your camera, microphone, photos, or contacts. --- ## Data Retention - **Data you enter** stays on your device until you delete it within the Application or uninstall the Application. Uninstalling removes the local database and all data you have entered. - **Anonymous analytics and crash data** are retained by the respective third-party providers according to their retention policies. - **Subscription status** is retained by RevenueCat and the app stores for as long as needed to manage your subscription. --- ## Children's Privacy The Application is not directed at children under the age of 13 (or the minimum age required in your jurisdiction). We do not knowingly collect personal information from children. Because the Application does not collect personal identity data, no such information is gathered from any user. --- ## Security We rely on the on-device storage protections of your operating system to safeguard the data you enter. Because your travel data never leaves your device, it is not exposed to server-side breaches. Anonymous data transmitted to third-party providers is sent over encrypted connections. --- ## Your Choices - **Delete your data:** Remove trips and travellers within the Application, or uninstall the Application to erase all locally stored data. - **Disable notifications:** Turn off notification permission in your device settings. - **Manage subscriptions:** Manage or cancel your subscription through your Apple App Store or Google Play account settings. --- ## Changes to This Policy We may update this Privacy Policy from time to time. Updates will be reflected by the "Last Updated" date above. Continued use of the Application after changes take effect constitutes acceptance of the revised Policy. --- ## Contact If you have questions about this Privacy Policy, contact us at: **NEXTLINE YAZILIM LİMİTED ŞİRKETİ** Email: support@nextline.software --- *This Application provides informational calculations only and does not constitute legal or immigration advice.
