3 Best Options to Clear App Data on iPhone
Now that we’ve covered the basics, let’s dive into practical steps. There are three main ways to clear app data on an iPhone, each suited for different situations. Some apps allow you to delete cached files directly, while others require system-level removal. App data stored in iCloud can also be managed separately. Here’s how to do it.
Option 1: Delete App Data from Specific App Settings
Some apps let you clear cached files, downloaded content, or other unnecessary data directly from their settings. This is the easiest way to remove junk without uninstalling the app, though it depends on the app itself. If available, you’ll usually find it under settings labeled Storage, Data, or Downloads—though names may vary by app.
Social Media Apps
Many social media apps allow users to manage data directly within the app. For example, in Snapchat, you can access the app settings to clear the cache, freeing up space without deleting the app entirely.
-
Open the app and navigate to your profile.
-
Tap on the Settings or gear icon.
-
Scroll down and select Clear Data under the Privacy Controls section.
-
Tap on a specific cache type like Lens Cache or just All Cache.
-
Confirm deletion.
Streaming Apps
Streaming applications, such as Netflix or Spotify, store offline content like downloaded shows or music. Clearing this downloaded content from the app settings can help in reclaiming storage space.
-
Open the streaming app.
-
Go to Downloads or Library.
-
Select and delete downloaded shows or music.
Note. Some apps can automatically clear data – Certain apps allow automatic cache clearing either after a set period or when a specific storage limit is reached. For example, Telegram offers both options—it can auto-remove cached data after a chosen time and also lets you set a maximum cache size.
Once that limit is reached, some apps will automatically clear the oldest, unused data. It’s worth checking your app’s storage settings—some apps offer this feature natively.Option 2: Delete App Data in iPhone Settings
If an app doesn’t provide built-in options to clear cache or stored data, you can manage it through the iPhone’s Settings. Essentially, this involves deleting the app itself, which removes all associated data from your device.
-
Open Settings and go to General > iPhone Storage.
-
Browse the list and select the app whose data you want to clear.
-
Tap Delete App to remove the app and all its associated data.
-
Reinstall the app from the App Store if needed, starting fresh without the old data.
Note: You may have noticed the Offload App button—it does the opposite of clearing app data. Instead of removing stored files, it deletes the app but keeps all its data on your iPhone. When you reinstall the app, everything returns as if nothing changed. This is useful for temporarily freeing up space without losing important files, but it won’t reset the app or remove cached data.
Option 3: Clear App Data from iCloud
If an app stores data in iCloud, deleting it from your iPhone won’t remove everything. Many apps sync files, backups, and settings across devices, keeping them in iCloud even after the app itself is deleted. To remove app data completely, you’ll need to clear it directly from iCloud as well.
-
Open Settings and tap your name at the top.
-
Go to iCloud.
-
Then tap Storage or Manage Storage (the exact option depends on your iOS version).
-
Scroll down and select the app storing data in iCloud.
-
Tap Delete Data From iCloud, then confirm.
This permanently removes the app’s data from iCloud, which means it cannot be recovered later. If the app is still installed on another Apple device, it might sync new data back to iCloud after deletion. To prevent this, go to Settings > [Your Name] > iCloud and disable iCloud access for the app before deleting its data.
Can I Use Third-Party Apps to Clear App Data?
No. You may have seen apps claiming to clean junk files and free up storage on your iPhone. While they can remove certain files, iOS does not allow third-party apps to clear app data or cache directly. Apple keeps app data locked down for security and privacy. Unlike Android, iOS sandboxes every app, meaning each operates in its own isolated environment. This prevents one app from accessing another app’s data or modifying system files.
Any app that claims to “deep clean” app cache or reset app storage is either misleading or potentially a privacy risk. Avoid these apps.
More Ways to Free Up Storage Beyond App Data
While third-party apps can’t clear app data, they’re still highly useful for freeing up storage in other ways. They can identify gigabytes of unnecessary files you can safely delete, helping reclaim space without affecting important data.
We’ve tested dozens of cleaner apps on the App Store and even have a separate ranking for AI-powered cleaners. Some of the best include Clever Cleaner, CleanMy®Phone: Storage Cleaner, and Clean Up Storage – Cleaner Kit.
If you haven’t tried these apps before, Clever Cleaner: Free Storage Cleaner is the best starting point. It’s fast, effective, and appears on both our traditional and AI-powered cleaner rankings. What sets it apart? Unlike most similar apps, Clever Cleaner is completely free—no ads, no in-app purchases, no paywalls. You can try it risk-free.
The app focuses on the biggest storage culprits on your iPhone. After app data, the largest space consumers are your media files. Here’s what Clever Cleaner targets:
-
Duplicate & Similar Photos (Similars) – Unlike the Photos app, which only detects and merges identical duplicates, this app finds both exact duplicates and visually similar photos, like shots taken from different angles or with slight variations. It groups similar photos together and gives you the option to either: delete them all automatically in one tap, or use an “almost-automatic” mode, where you review and decide what to keep or remove. It uses AI to analyze photos and even suggests the “Best Shot” to keep. In our experience, it’s usually highly accurate. -
Large Video Files (Heavies) – Finds and highlights big video files that take up storage but may no longer be needed. Unlike the Photos app, which doesn’t allow you to sort by size, this tool lists all your videos from largest to smallest, so you can quickly delete the biggest space-wasters. -
Live Photos – It can compress Live Photos and free up a lot of space in the process. The app calls it “Compress,” but what it actually does is convert Live Photos into normal still images without the short video clip that plays when you open them. This saves a huge amount of space without reducing quality. -
Screenshots – It easily identifies all the screenshots you’ve taken. Unlike the Photos app, which mixes screenshots with regular photos, this tool sorts them all in one place, so you can review and delete them in bulk.
That’s all four features you can use right now to free up space. But according to the official Clever Cleaner app page:
“Download Clever Cleaner today and enjoy lifetime access for free. Early users will never be asked to pay for upgrades or new features.”
We believe the developer, CleverFiles, plans to add more tools in the future. Features we’d love to see include video compression, similar video detection, and contact cleanup. Still, not bad for a completely free app. And if it really stays free—even as new features are added—it’s worth keeping on your iPhone just in case. Need more details?

The Bottom Line
If you like skipping to the summary, here’s a quick overview of your options. The best approach depends on your goal—whether you want to free up storage or clear app data entirely.
If you just want to free up storage:
-
Use built-in app options – Some apps let you clear cache or downloaded files directly in settings (e.g., Facebook, Snapchat, YouTube).
-
Use a third-party cleaner – Apps like Clever Cleaner can remove duplicate photos, large videos, Live Photos, and old screenshots.
If you want to clear app data completely:
-
Delete the app – This removes all cached data and resets the app (Settings > General > iPhone Storage > Delete App).
-
Clear iCloud backups – If the app syncs with iCloud, delete its data from Settings > [Your Name] > iCloud > Manage Storage to remove stored files across devices.
If you’re handing your iPhone to someone else, it’s better to reset it completely rather than clearing app data individually. This wipes everything—apps, accounts, personal files, and saved settings—ensuring nothing is left behind.
