Reinstall the app without losing my data

What's on your device vs on our servers

On our servers (so preserved if you reinstall):

• Your account (e-mail address, username, validated KYC).
• Your KTK balance.
• All your ongoing and resolved challenges.
• All your ongoing and resolved predictions.
• Your transaction history (deposits, withdrawals).
• Your friends, followers, and people you follow.
• Your private leagues and their internal rankings.
• Your Devin score, your badges, your trophies.
• Your ongoing disputes.
• Your notification settings.

On your device (so erased on reinstall):

• The visual cache (images, thumbnails).
• Your custom feed filters (to set up again).
• Your unsynced local drafts (rare).
• Your local theme preferences (dark/light mode).
• Your local chat history beyond what's on the server.
• Your login token (you'll have to log back in).

The clean reinstall procedure

The app only exists on Android, in beta: there's no iPhone app yet (Ktkarena on iPhone: no app yet).

Step 1 - Mental backup (optional but recommended):
Before uninstalling, make a mental note or take a screenshot of:

• Your active feed filters (if you have any).
• Your theme (dark/light) if you care about it.
• Your pending drafts (send them before uninstalling so you don't lose them).

Step 2 - Uninstall:

1. Long-press the Ktkarena icon → Uninstall → Confirm.
2. Optionally, also clear the remaining data: Android Settings → Apps → Ktkarena → Storage → "Clear all data" (before uninstalling).

Step 3 - Reinstall: the app isn't on Google Play.

1. On your phone, open ktkarena.com/telecharger-beta: the file of the latest version of the beta downloads.
2. Open the file and install it. If Android blocks the install, allow the app that opens the file to install apps (Download the app on Android).

Step 4 - Log back in:

1. Open the app.
2. On the sign-in screen (not “Create an account”!), enter your e-mail address, tap “Send my code” and enter the code you receive. Or tap “Continue with Google”.
3. If you use a password: enter it and tap “Sign In”; if two-factor authentication is on, also enter the code from your authenticator app.
4. You're back. Your entire account is there.

Setting things up again after reinstalling

On first launch after reinstalling, you see your account normally. But some local settings may have been reset. Check:

1. System permissions:

• Notifications: allow push.
• Camera: allow (for future KYC, disputes).

2. Ktkarena preferences:

• Profile → Notifications: set your notification types again if needed.
• Profile → Appearance: set the theme (dark/light) again if you care about it.
• Profile → Performance: re-enable data saver mode if you were using it.

3. Check your drafts:
If you had pending drafts, check that they were sent before uninstalling. Otherwise, they're lost.

When to reinstall (and when not to)

Reinstalling is useful when:

• The app refuses to launch.
• The app crashes systematically after a few minutes.
• You're seeing persistent abnormal behavior even after clearing the cache.
• You did a big OS update and the app has issues.
• You're switching phones (on the new one, it's a "first install" but the account is recovered).

Reinstalling is useless when:

• You just have a network connection problem (server issue, your WiFi).
• You forgot your password (use "Forgot password").
• You want to change your e-mail address (use the dedicated procedure: Change my e-mail address).
• You want to delete your account (different procedure). Closing my account.
