What We Collect

Inventle collects anonymous gameplay statistics to improve the game and power features like global leaderboards. This includes:

• Number of guesses per puzzle
• Bonus round results
• Approximate country (derived from IP address)
• General device type (mobile/desktop)

What We Don't Collect

• No IP addresses stored — ever
• No names, emails, or account information
• No precise location data
• No personal identifiers of any kind
• No device fingerprinting or cross-session tracking
• No cookies for tracking (only ad network cookies if applicable)

IP Addresses & Identifying Data

We never store IP addresses. When gameplay stats are submitted, a third-party geolocation service determines your approximate country from your IP. The IP is processed in-transit only and is never logged, saved, or recorded by Inventle in any form. We have no way to identify, track, or re-identify any individual player. All stored data is fully anonymous and cannot be linked back to any person or device.

Local Storage

Your game progress, statistics, and preferences (theme, color scheme, animation settings) are stored locally on your device using browser localStorage. This data never leaves your device.

Advertising

Inventle may display advertisements through third-party ad networks (such as Google AdSense). These networks may use cookies to serve ads based on your browsing activity. You can manage cookie preferences through your browser settings.

Data Sharing

We do not sell, trade, or share any collected data with third parties, except as required by ad network integrations described above.
