How Fränk Protects Your Game Progress
We want every round to feel fair – without cheaters, fake highscores, or unnecessary data collection. Here's how we make that happen technically.
🎮 Fair Play for Everyone
Points, coins, and highscores in Fränk cannot be simply "boosted". All critical values are verified and stored exclusively on the server – not in the app.
- No direct client write access to game progress
- All runs are validated server-side
- Leaderboard entries cannot be faked
Result: If you're at the top, you actually earned it.
🔐 Your Data, Your Game
We only store what's really necessary for the game: your runs, your coins, your highscores, and which skins you've unlocked.
We DO NOT collect: Contacts, location, address book, sensitive or personal content.
🛡️ Anti-Cheat & Replay Protection
To prevent cheating, Fränk uses multiple security layers that all run on the server.
1. One-Time Run Sessions
When you press Play, the server generates a unique session ID (run_session_id). This is:
- valid only for this specific run
- linked to your account
- time-limited (e.g., 30 minutes)
- usable only once
If the same session ID is used multiple times, the server blocks the attempt as a replay cheat.
2. Time Validation (Anti-Speedhack)
The server remembers your run's start time. At game end, the app reports the elapsed time. We compare:
- reported duration from the app
- calculated duration from server perspective
If the time deviates too much (e.g., more than a few seconds), the run is marked as a speedhack attempt and not counted.
3. Logic Checks for Score & Coins
To prevent unfair values, there are server-side limits and plausibility checks.
- Maximum allowed score per run
- Maximum coin count per run
- Calculation of score per second (score / playtime)
If a value is far outside the expected range, the run is rejected – before anything is saved.
4. Mission & Difficulty Verification
The mission and difficulty reported by the client must exactly match the session created at start. If someone tries to change this afterwards, the server blocks the run.
🏆 Leaderboard Protection
Highscores in the leaderboard are only updated when a run passes all security checks. The client cannot directly create or edit leaderboard entries.
- Leaderboard entries are written exclusively server-side
- Each new highscore is checked for plausibility
- Manipulation via network tools or app modifications do not result in valid entries
This keeps the competition fair – regardless of which device you play on.
🌍 What We DO NOT Do
We care about you having fun in the game – not about your private life. Therefore:
- no access to your contacts or photos
- no location tracking
- no analysis of personal content
- no sharing of your data with third parties
Data is stored on secure servers following the principle of data minimization.
