How to clear the cache

Why clear the cache

The cache is a folder of temporary data the app stores on your phone to load faster:

• Profile photos of your friends and opponents.
• Event thumbnails.
• Sports team logos.
• Previous results for instant display.
• JavaScript files of the embedded web app.

Benefits of the cache: faster navigation, less mobile data used.

Downsides when it gets big or corrupted:

• The app lags or freezes.
• Some images no longer appear (or appear broken).
• Strange error messages pop up.
• The phone runs low on overall storage.

Clearing the cache is the first thing to try when the app is slow.

Recommended frequency: you don't need to do it regularly. Only when the app behaves abnormally.

The Android procedure step by step

1. Open the Android Settings (the gear).
2. Tap "Apps" or "Applications" (the name varies by brand).
3. Find Ktkarena in the list and tap it.
4. Tap "Storage" or "Storage & cache".
5. You see two buttons:
   • "Clear cache": deletes only temporary data. This is the one to use.
   • "Clear data" or "Clear storage": also deletes your local preferences (language, theme) and logs you out. Avoid except as a last resort.
6. Tap "Clear cache". No confirmation asked - it's instant.
7. Go back to the home screen and relaunch Ktkarena.

The app should be faster. On the first launch after clearing, it may be a bit slower while it re-downloads visual elements.

Clearing by age: on some recent Androids, you can also tap "Cache → Clear cache older than [X] days". Useful if you want to keep the recent cache.

What about iPhone?

There's no Ktkarena app for iPhone yet: nothing to clear. If you use the web version, at app.ktkarena.com, simply reload the page (Ktkarena on iPhone: no app yet).

What you do NOT lose

It's important to be clear: clearing the cache doesn't touch your data at all. Here's what is preserved:

• Your account: you stay logged in.
• Your KTK balance: intact, down to the last KTK.
• Your challenge and prediction history: fully preserved.
• Your badges and trophies: all kept.
• Your friends, follows, private leagues: no changes.
• Your ongoing disputes: continue normally.
• Your ongoing challenges: proceed to resolution as planned.

All of that lives on our servers, not in the local cache. The cache only contains visual and technical elements for display.

What you may lose (minor):

• Your feed filtering preferences (to reconfigure if you had custom filters).
• The chat history cache (old messages reload as needed).
• Offline-mode images (to re-download).
