A cache is a store of temporary files an app or browser keeps on your phone so it can load things faster next time, such as images, game graphics and lobby layouts. In a casino app, clearing the cache is a common fix for slow loading or display glitches, and it doesn't touch your account balance, which is held by the operator.
Cache is temporary data saved on your phone to speed up loading.
Clearing the cache is different from clearing an app's storage, which also signs you out.
Android lets you clear an app's cache directly; on iPhone you usually reinstall the app.
Your balance and bet history live on the operator's systems, not in the cache.
Update the app first, as an old version is a more common cause of problems.

What a cache is
The word comes from the French for a hiding place, and that's roughly what it is: a hidden store of files your phone keeps close at hand. When a casino app opens its lobby, it may save thumbnails, fonts and parts of game screens so they don't need downloading again on your next visit.
Caches make apps feel quicker and use less mobile data, but they can grow over time and occasionally hold onto outdated files. That's when they cause trouble. This term sits with HTML5 and native app in our glossary of casino app terms.
Casino app cache vs app data vs your account
Three different things are easily confused. Knowing which is which tells you what you'll lose when you clear something.

What clearing it does
Cache
Your phone, temporary
Removes saved images and files; the app rebuilds them as you use it
App storage or data
Your phone, longer-term
Resets the app: signs you out and clears saved settings on the device
Account, balance and bet history
The operator's systems
Not affected by anything you clear on your phone
Store download size

The size of the installed app before cache builds up
Download sizes give a sense of scale before any cache is added. The App Store lists Coral Casino at 101.6 MB, Ladbrokes Casino at 101.2 MB, Casumo at 52.5 MB, PlayOJO at 25.4 MB and 10bet (opens in a new tab) at 112.3 MB. Our guide to casino app storage space explains how much room to leave free.
When clearing the cache helps
The lobby or a game screen shows old images or a layout that won't refresh.
Pages load slowly even on a good connection.
The app freezes on a loading screen after an update.
Your phone is running low on storage.
It's less likely to fix login errors, declined payments or a failed location check, which come from the operator's side or your settings. For those, try our guides to casino app login problems and an app that won't open.
How to clear a casino app cache on Android and iPhone
On Android
Close the casino app.
Open Settings and go to Apps (sometimes Apps and notifications).
Choose the casino app, then Storage (or Storage and cache).
Tap Clear cache. Leave Clear storage alone unless support asks you to.
Reopen the app and give it a moment to rebuild the lobby.
On iPhone
iOS doesn't usually offer a clear-cache button for individual apps. The common approach is to delete the app and reinstall it from the App Store, which removes its stored files. You'll need to log in again, so have your password ready. Menu wording varies by phone and software version, so look for the nearest match.
If you play in Safari or Chrome rather than an app, the browser keeps its own cache for each site. Clearing browsing data there works in a similar way but can also remove saved cookies, which signs you out of sites and may reset cookie choices. A web app added to your home screen relies on the browser's storage too.

Frequently asked questions
Will clearing the cache delete my casino account?
No. Your account, balance, bonuses and bet history are held by the operator, not on your phone, so clearing the cache leaves them untouched. At most, you might need to log in again, particularly if you clear app storage rather than just the cache. If you want to close an account, that's done through the operator. Our guide on closing a casino account explains how.
What's the difference between clear cache and clear storage?
Clear cache removes temporary files such as images and game graphics, which the app rebuilds as you use it. Clear storage, sometimes called clear data, wipes everything the app has saved on your phone, so it behaves like a fresh install and signs you out. Try clearing the cache first. Our casino app not working guide lists other fixes to try before resetting an app completely.
How do I clear the cache on an iPhone casino app?
Most iPhone apps don't have a clear-cache button, so the usual method is to delete the app and reinstall it from the App Store. That removes its stored files. Make sure you know your login details first, as you'll need to sign in again. Some apps include their own option to clear data in their settings, so check there too. Our iPhone download guide covers reinstalling.
Does a full cache slow down a casino app?
A cache is meant to speed things up, but a very large or corrupted one can cause slow loading or display problems, and it uses storage space your phone may need. If an app is sluggish, update it, check your connection and then clear the cache. Persistent crashes may point to an older phone or software version. Our guide to casino apps on older phones covers that case.
Does clearing the cache affect a game in progress?
Close the game before clearing anything. The outcome of a round is handled by the operator's systems rather than stored in your phone's cache, but interrupting a game is never ideal, and the operator's rules decide how an unfinished round is settled. Check the game's help screen for details. Our guide on what happens to a bet if your app crashes explains the usual approach.
