Revi-Sana

1. Introduction

Welcome to Revi-Sana! At UNISHOP LLC, we take your privacy and the security of your personal data very seriously. Revi-Sana was built with a strict "privacy-by-design" philosophy. Your study progress, exam results, and preferences remain securely in your hands at all times. This Privacy Policy outlines our transparent practices regarding data handling when you use the Revi-Sana iOS application.

Revi-Sana is a native iOS learning application designed to help Swiss candidates prepare for the Swiss fishing license (Attestation SaNa / SaNa-Ausweis). The app provides a bilingual (French/German) multiple-choice question bank, using a Leitner spaced-repetition revision system and timed mock exams. The app is accessible to anyone from 10 years of age, which is the official minimum age to obtain the SaNa in most Swiss cantons.

2. Data Collection and Local Storage

Revi-Sana does not collect, transmit, store on remote servers, or share any personal data. The app operates with a fully local storage model and works 100% offline.

• Local Device Storage: All data is stored exclusively and locally on your iPhone using Apple's native SwiftData framework and UserDefaults. Nothing is sent to any external server.
• No Account Required: Revi-Sana does not require any sign-up, login, email address, password, or account creation. You can start training immediately without providing any personal information.
• No Cloud Servers: UNISHOP LLC does not operate any external servers, cloud databases, or custom backends for Revi-Sana. Your data never leaves your device. There is no cloud. There is no backend.
• No Personal Identifiers: We do not collect your name, email, phone number, or any other personally identifiable information.
• No Data Harvesting: We do not collect, read, analyze, or transmit any of your data. Because we never possess your data, we will never sell or share it with third parties.
• No Telemetry & Analytics: We do not collect usage statistics, crash logs, or any performance metrics.
• No Ads or Tracking: The app contains no advertisements, no Apple IDFA (Identifier for Advertisers) tracking, and no tracking pixels or SDKs.

3. Data Stored on Your Device

For transparency, here is a complete list of data that Revi-Sana stores locally on your device:

• Question Revision Progress: Spaced-repetition states (Leitner boxes), mastery levels, and last revision dates for individual questions.
• Personal Statistics: Daily streak count, completed revision sessions, and overall success rates.
• User Preferences: App language selection (French/German) and notification settings (opt-in/opt-out).
• Premium Status: Your Pro status, validated locally via Apple's secure StoreKit framework.

All of this data is stored in the application's local container using SwiftData and UserDefaults. It is automatically and permanently deleted by the iOS operating system when you uninstall the app.

4. Analytics and Third-Party SDKs

We respect your privacy and device performance. Revi-Sana intentionally excludes all third-party tracking algorithms and analytics SDKs (such as Firebase, Mixpanel, Amplitude, Facebook SDK, Google Analytics, or RevenueCat). We do not monitor your behavior within the app. Zero tracking, zero analytics, zero ads—by design.

5. Apple Privacy Manifest

Revi-Sana includes a PrivacyInfo.xcprivacy manifest as required by Apple, declaring the following:

• UserDefaults (NSPrivacyAccessedAPICategoryUserDefaults): Used for storing user preferences locally on the device (reason CA92.1).
• Tracking: None. The app does not use the App Tracking Transparency framework because there is nothing to track.

6. In-App Purchases and Subscriptions

Revi-Sana operates on a freemium model with optional Pro upgrades to unlock the full question bank and advanced features.

• Purchase Plans:
  • Monthly Subscription – CHF 4.90 / month
  • Annual Subscription – CHF 29.90 / year
  • Lifetime Purchase (One-time) – CHF 59.00
• Secure Transactions: All purchase transactions are processed exclusively via Apple's secure StoreKit framework and your personal Apple ID.
• Financial Privacy: UNISHOP LLC does not process your payment and has zero access to your sensitive financial information (such as credit card numbers or billing addresses). The app only receives confirmation from Apple, and UNISHOP LLC receives only aggregated sales reports (such as country and purchase volumes) that contain absolutely no personally identifying information. Apple's privacy policy applies for the payment part: apple.com/legal/privacy.
• Purchase Restoration: You can restore your purchases at any time through the app. This process communicates exclusively with Apple's servers—never with UNISHOP LLC.
• Cancellation: You can manage or cancel your subscription at any time through your Apple ID settings or the App Store. Cancellation takes effect at the end of the current billing period.

7. Notifications

Revi-Sana may request permission to send local notifications to remind you to study (such as a daily revision reminder scheduled for 7:00 PM / 19h).

• Local Notifications Only: Revision reminders are scheduled and delivered locally on your device by the iOS operating system itself using Apple's UserNotifications framework. No data is sent to any external server.
• No Notification Servers: We do not use any remote push notification servers. No data or device tokens are sent to any external server.
• Full User Control: Notifications require your explicit permission. You can enable, disable, or adjust them at any time in the app settings or via iOS system settings.

8. Children's Privacy

Revi-Sana is designed for everyone preparing for the Swiss fishing exam, including children starting from 10 years of age (the official minimum age to pass the SaNa in most Swiss cantons). Because Revi-Sana collects absolutely no personal data, no account registration is required, and no data is transmitted to us, the app is fully compliant with children's privacy regulations including COPPA (Children's Online Privacy Protection Act) and the GDPR's provisions for minors. No parental consent is technically required due to the absolute lack of data collection.

9. Your Rights & Data Control (GDPR / Swiss nLPD)

Revi-Sana is designed in compliance with the General Data Protection Regulation (GDPR) and the Swiss Federal Act on Data Protection (nLPD).

Since UNISHOP LLC does not collect, store, or transmit any of your personal data, there is no personal data held by us. Therefore, rights of access, rectification, or erasure do not apply at our level because we do not possess any of your data. Instead, you have total direct control over your data:

• Reset Progress: You can reset all your learning statistics and progress at any time directly in the app from Settings → Reset.
• Complete Deletion: You can delete all locally stored data simply by uninstalling the application from your iOS device.

10. Visual Credits and Attributions

Revi-Sana features 15 species photos sourced from Wikimedia Commons under free licenses (CC0, Public Domain, CC-BY, CC-BY-SA). The complete attributions, licenses, and author credits for each photo are fully documented inside the application and can be accessed under Settings > Credits (compiled in the PHOTO_CREDITS.md file).

11. App Store Compliance

In accordance with Section 5.1 (Privacy) of the App Store Review Guidelines, Revi-Sana provides this policy to clearly disclose what data the application collects, how that data is used, and how you can manage or delete your data.

12. Changes to This Policy

We may update our Privacy Policy occasionally to reflect changes in our app's features or legal requirements. Because we do not collect your email address or contact information, we cannot notify you individually. We encourage you to review this page periodically. Any modifications take effect immediately upon being posted on this site.
