Clearing the cache on Snapchat removes temporary files the app stores on your device to help it run faster. These files include thumbnail previews of images and videos, cached stickers and filters, and lens data. Over time, these files can accumulate and take up significant storage space, potentially slowing down the app's performance. Clearing the cache frees up this space and can make Snapchat run more smoothly. Importantly, clearing the cache does not delete any of your saved Memories, Snaps, Chats, or personal data, but it may remove saved lenses and filters temporarily. This process is safe and can be done from Snapchat's settings under "Clear Data" or "Clear Cache," and it's especially helpful if the app is lagging or taking too much space.
