Privacy policy

1. Introduction

This Privacy Policy explains how Klewos (“the App”, “we”, “our”, “us”) collects, uses, and protects your information when you use the app. We are committed to respecting your privacy and ensuring the minimal collection of user data.

By using Klewos, you agree to the practices described in this policy.

2. Age Restrictions

Klewos is intended for users who are 13 years of age or older. If you are under 13, you are not permitted to use the app.

3. Data We Collect

We do not collect any personal information such as names, email addresses, or contact details.

The only data collected is a randomly generated user identifier (“userId”), which is used internally for the following purposes: • Managing purchases and subscriptions via RevenueCat • Analyzing app usage through Amplitude (aggregated, anonymized data) • Diagnosing crashes using Crashlytics

We do not link this userId to any personal identity.

4. How We Use Data

The data collected is used solely for: • Verifying and restoring purchases • Understanding general usage patterns (e.g., which features are most used) • Improving stability and performance of the app

No data is ever sold, shared, or used for advertising purposes.

5. Third-Party Services

We use the following third-party services, which may process limited data (such as your userId or technical logs): • RevenueCat (In-App Purchase and Subscription Management) https://www.revenuecat.com/privacy • Crashlytics (Crash Reporting, part of Google Firebase) https://firebase.google.com/support/privacy • Amplitude (Usage Analytics) https://amplitude.com/privacy

These services operate in accordance with their own privacy policies and comply with relevant data protection laws such as the GDPR.

6. Offline Usage

Klewos can be used offline. However, some features — such as syncing purchases, retrieving updates, or sending crash logs — may require an internet connection.

7. Your Rights

If you are a resident of the European Union, under the GDPR, you have the right to: • Access the data we hold about you (which is limited to your userId and technical logs) • Request deletion of your data • Object to data processing

To exercise your rights, please contact us at [email protected].

8. Data Retention

We retain technical data only as long as necessary for app functionality, analytics, and legal compliance. If you delete the app, any associated userId and crash/analytics data will eventually be purged automatically by the third-party services listed above.

9. Security

We take appropriate technical and organizational measures to protect data against unauthorized access, alteration, disclosure, or destruction.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We encourage you to review it periodically. If changes are significant, we will notify users through the app or App Store update notes.
