Effective Date: June 17, 2026
Last Updated: June 17, 2026

1. Introduction

prelol ("the App", "we", "our", or "us") is developed by Fatih Demir. This Privacy Policy explains what information we collect when you use prelol, how we use it, and what rights you have.

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

2. Information We Collect

2.1 Account Information

When you sign in, Firebase Authentication (provided by Google) handles your identity. Depending on your sign-in method, Firebase may store your email address and a unique user identifier (Firebase UID). We do not receive or store your password.

We do not maintain our own user database. Your identity is managed entirely through Firebase Authentication.

2.2 League of Legends Game Data

To provide analysis, you enter a Riot ID (game name and tag line). The App sends this identifier to our backend server, which uses the Riot Games API to retrieve:

• Summoner profile information (rank, level)
• Match history
• Champion performance statistics
• Champion mastery data
• Live game participant data (when a live game is detected)

All of this data is public — it is the same data visible on tools like OP.GG or the Riot Games client. We do not access your Riot account, password, or any private account settings.

This data is used only to generate analysis results for you. It is cached in server memory for short periods (minutes) to reduce API load, and is never written to a permanent database.

2.3 Analytics Data

The App uses Firebase Analytics to collect anonymous usage data such as:

• Which screens are viewed
• Which features are used
• Session length and frequency

This data helps us understand how the App is used and improve the experience. It does not identify you personally and is processed in aggregate.

2.4 Crash Reports

The App uses Firebase Crashlytics to automatically report crashes. When a crash occurs, Crashlytics may send:

• Device model and OS version
• App version
• A stack trace of the crash
• App state at the time of the crash

Crash reports do not include personal information such as your name, email, or game data.

2.5 Performance Data

The App uses Firebase Performance Monitoring to measure network request latency and screen rendering performance. This data is anonymous and used solely to identify performance issues.

2.6 Advertising Data

If you are a free user, the App displays ads served by Google AdMob. AdMob may collect device identifiers and usage signals to serve relevant ads, subject to Google's own privacy policies. You can opt out of personalized advertising through your device settings (iOS: Settings → Privacy & Security → Apple Advertising; Android: Settings → Google → Ads).

2.7 Subscription Data

Subscriptions are managed by Adapty. When you purchase a subscription, Adapty processes your purchase receipt and entitlement status. We do not receive or store your payment card details; those are handled entirely by Apple's App Store.

3. How We Use Your Information

We use the information described above to:

• Authenticate you and maintain your session
• Retrieve public League of Legends data to power analysis features
• Generate AI-powered match and performance insights using Anthropic's Claude AI
• Display advertising to free users
• Manage subscription entitlements and remove ads for premium users
• Detect and fix bugs and crashes
• Understand usage patterns to improve the App

We do not sell your personal information. We do not use your data for profiling or automated decisions that have legal or significant personal effects.

4. Third-Party Services

prelol relies on the following third-party services. Each has its own privacy policy:

We only share the minimum data required with each provider to deliver the relevant feature.

5. Data Retention

• Firebase account data: Retained until you delete your account (see Section 7).
• Analytics and crash data: Retained per Firebase's default retention policies (up to 14 months for Analytics).
• Server-side game data cache: Held in memory for minutes and discarded automatically; never written to permanent storage.
• Subscription records: Retained by Adapty per their policies.

6. Children's Privacy

prelol is not directed at children under the age of 13 (or under 16 in applicable jurisdictions). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us at fthdmirr@gmail.com and we will delete it promptly.

7. Your Rights and Data Deletion

Depending on your location, you may have the right to access, correct, or delete the personal data we hold about you.

To request account deletion:

1. Email fthdmirr@gmail.com with the subject line "Account Deletion Request".
2. Include the email address or Riot ID associated with your account.

We will delete your Firebase account and any associated data we control within 30 days. Note that we do not maintain a backend database of user records — the only personal data we hold is your Firebase authentication record.

Analytics and crash report data is anonymized and cannot be retroactively deleted by user.

8. Data Security

We use industry-standard practices to protect your data:

• All communication between the App and our backend uses HTTPS.
• Firebase ID tokens are verified on every authenticated request.
• API keys and secrets are never exposed to the client.
• Our backend does not write game data to any persistent database.

No method of transmission or storage is 100% secure, but we take reasonable measures to protect your information.

9. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last Updated" date at the top of this document. Continued use of the App after changes constitutes your acceptance of the updated policy. For material changes, we will provide notice within the App.
