Frequently Asked Questions
What is CalDex?
CalDex is a free web-based platform offering calculators and tools for popular games like Genshin Impact and Fortnite. Our tools help you track pity counts, view daily item shops, calculate resources needed, and plan your pulls efficiently. Everything works offline and requires no account or login.
Is CalDex completely free?
Yes! CalDex is 100% free to use with no hidden costs, subscriptions, or premium features. You don't need to create an account or provide any personal information. We believe gaming tools should be accessible to everyone.
How is my data stored?
All your data is stored locally in your browser using localStorage. We never send your data to our servers or any third parties. Your pity counts, primogem totals, and all calculations remain completely private on your device.
Does CalDex work offline?
Yes! Once you've loaded the calculator page, you can use it offline. All calculations happen in your browser, and your data is saved locally. The Fortnite Item Shop requires internet to load fresh data, but Genshin calculator works fully offline.
Can I use CalDex on mobile?
Absolutely! CalDex is fully responsive and works perfectly on mobile phones, tablets, and desktop computers. The interface adapts to your screen size for optimal usability on any device.
Will my data sync across devices?
Currently, data is stored locally per device/browser. If you use browser sync (like Chrome sync), your data may sync across devices using the same browser account. We're considering adding manual export/import features in future updates.
Which games do you support?
Currently, we have a fully functional Genshin Impact pity calculator and Fortnite Daily Item Shop tracker. We're working on adding calculators for Honkai: Star Rail, Wuthering Waves, and other popular games. Check the "Coming Soon" section for updates.
How can I report bugs or suggest features?
We welcome feedback! While we don't have a dedicated contact form yet, you can report issues or suggest features by posting in the communities where you found CalDex (like Reddit). We actively monitor user feedback to improve the platform.
