Privacy Policy

Eye Exercises: Vision Training is operated by Olnikola studio (“we”, “us”, or “our”).

This Privacy Policy explains how Eye Exercises handles information when you use the app.

1. Overview

Eye Exercises is designed to work with minimal personal data.

The app currently does not require account registration to use core features. Most app data is stored locally on your device. Limited anonymous analytics and crash-diagnostics data is processed by third-party services to help us keep the app working reliably and to improve it.

2. Information the App Uses

Depending on how you use the app, the app may process the following categories of information.

A. Information Stored Locally on Your Device

The app may store:

• onboarding completion status
• an optional local display name, if you choose to set one
• custom training routines you create
• reminder preferences, including selected weekdays and times
• local training history and completed session events

This information is used to provide the app’s features and improve continuity of your experience on your device.

B. Notifications Data

If you enable reminders, the app may request permission to send local notifications. Reminder schedules are used to generate notifications on your device.

The app does not require you to enable notifications in order to use core exercise features.

C. Purchase and Subscription Data

If you use paid features, subscription and purchase-related information may be processed through Apple and RevenueCat.

This may include:

• product identifiers
• entitlement status
• purchase state
• subscription expiration or renewal-related status

This data is used to determine whether premium access is active and to support purchase and restore flows.

D. Analytics and Diagnostics Data

To understand how the app is used and to improve stability, the app processes limited anonymous data through Google Firebase. This data is not linked to your identity and is not used to track you across other apps or websites.

• Usage analytics (Firebase Analytics): anonymous usage data such as screens viewed, in-app events (for example, starting or completing a session, viewing the upgrade screen), session activity, purchase events, and an app-generated identifier (app-instance ID). This may include a coarse, region-level location derived from your IP address.
• Crash diagnostics (Firebase Crashlytics): diagnostic data generated when the app encounters an error or crash, such as crash reports and stack traces, device model, operating system version, and app version.

3. Third-Party Services

The app currently uses the following third-party services in connection with app functionality:

• Apple, for App Store billing, subscription management, and purchase handling
• RevenueCat, for subscription status and purchase infrastructure
• Google Firebase Analytics, for anonymous usage analytics
• Google Firebase Crashlytics, for crash and stability diagnostics

If you use reminders, the app also uses iOS local notification infrastructure on your device.

• Google Privacy Policy: https://policies.google.com/privacy
• RevenueCat Privacy Policy: https://www.revenuecat.com/privacy

4. What the App Does Not Currently Do

Based on the app’s current implementation, the app does not currently require user account sign-in for core functionality.

The app also does not currently include:

• third-party advertising SDKs
• advertising or cross-app tracking
• social login
• in-app sharing of your training history with other users

The analytics and crash-diagnostics services described in Section 2.D collect only anonymous data that is not linked to your identity and is not used for advertising or cross-app tracking.

If these practices change in a future version, this Privacy Policy should be updated before release.

5. How Information Is Used

Information processed by the app is used to:

• provide guided eye exercise sessions
• save your app preferences locally
• store your custom routines and local history
• schedule and deliver reminders you configure
• determine premium access and restore purchases
• support subscription management and billing-related flows
• understand how the app is used so we can improve it (anonymous analytics)
• detect, diagnose, and fix crashes and stability issues

6. Data Sharing

We do not sell your personal information.

We do not share your local training data with advertisers.

Purchase-related data may be processed by Apple and RevenueCat as part of subscription and purchase handling. Anonymous analytics and crash-diagnostics data is processed by Google Firebase on our behalf. Their handling of data is governed by their own policies and terms.

7. Data Retention

Locally stored app data remains on your device unless you delete it, reset it, or remove the app.

Purchase and subscription records may be retained by Apple and RevenueCat, and analytics and crash-diagnostics data may be retained by Google Firebase, in accordance with their own operational, legal, and compliance requirements.

8. Your Choices

You may:

• decline notification permissions
• disable reminders in the app
• manage or cancel subscriptions in your Apple Account settings
• restore eligible purchases through the app
• remove locally stored app data by deleting the app or clearing app data where supported

9. Children’s Privacy

The app is not directed to children under the age at which parental consent is required in the applicable jurisdiction.

If you believe personal information from a child has been provided through app support channels or other external means, contact the app publisher so the issue can be reviewed.

10. Security

We use reasonable efforts appropriate to the app’s scope to reduce the risk of unauthorized access to information handled by the app.

However, no method of electronic storage or transmission is completely secure, and absolute security cannot be guaranteed.

11. International Users

If you use the app outside the country where the app publisher is located, information may be processed by Apple, RevenueCat, Google, or other service providers in jurisdictions where they operate.

12. Changes to This Privacy Policy

We may update this Privacy Policy from time to time.

If material changes are made, the updated version will be reflected by a new effective date.
