How do I clear Android cache without losing app data?

I regularly clear the cache on my phone and I've never run into any problems - app passwords stay in place, syncing works just like before. You can go even further: in that same "Apps" menu there's an option like "Clear Storage" or "Delete Data," but that deletes everything, including passwords, so you shouldn't touch that one. Cache is just temporary files that apps downloaded for faster performance, and deleting them won't damage functionality at all.

If you want to clear everything at once, in the system settings there's usually a section like "Storage" or "Memory" where you can select "Delete cache for all apps" in one go - quick and safe.

I'm happy to reassure you: cache can definitely be safely deleted. These are temporary files that apps download for faster performance - passwords, login data, and personal settings are stored separately and won't be affected when you clear the cache. So your worry is completely unfounded.

The simplest way is to go to Settings → Apps, select the app you need, and tap "Clear cache". If you have a lot of apps, it's easier to use the built-in utility: in the same Settings, find the "Storage" or "Memory" section - there's usually an option to clear the cache for all apps at once. It'll take a few seconds.

If you want to free up even more space, check out "Temporary files" in that same section - that's where leftovers from deleted apps and system temporary data pile up. You can definitely get rid of those without any consequences. But you shouldn't touch the "Clear data" option - that one will actually delete your passwords and settings. It's usually marked in red, but it's easy to mix it up with cache.

Don't worry - cache has nothing to do with your passwords and data, it's just temporary files that help apps run faster! Besides the standard cleanup through settings, I'd suggest checking inside the apps themselves: lots of them have their own menu for clearing cache, like in account settings or in a "Storage" section - you can often delete way more junk that way than with a system-wide cleanup.

Here's what I noticed from my own experience: if you just clear the cache through settings, you free up space, but it's the slowest way. It's much more effective to go into each app separately - in Settings → Apps you pick the one you need and tap specifically on "Clear cache," not "Delete data." It's actually safe because cache is just temporary files like images for quick loading. All your passwords, logins, and synced data are stored somewhere completely different.

There's one good trick that helps me: after you clear an app's cache, the app partly reinstalls the cache again, and that can take up space. So it makes sense to first check which apps are taking up the most cache - there are special analysis apps for that, or you can see the size of each one right in that menu. Often just two or three apps eat up half the junk, and the rest doesn't really matter.

If space is critically low, you can also check your Downloads and Documents folders - there are often old files lying around that you don't need anymore. But that's a separate thing, not related to cache.
