Frequently Asked Questions

Cleana is an AI-powered iPhone storage cleaner that automatically finds and removes duplicate photos, similar pictures, large videos, and unnecessary files from your photo library. It uses on-device machine learning to scan your library, group similar shots, analyze photo quality, and recommend the best photos to keep, all without uploading anything to the cloud.

Cleana combines precision AI (on-device), complete privacy (no cloud uploads), ease of use (swipe-to-delete interface), and broad capability (photos, videos, screenshots, contacts) in one app. Most alternatives either require cloud access or lack the AI quality-ranking feature that recommends which photo to keep.

Cleana is compatible with any iPhone running iOS 15.0 or later, covering a wide range of models from iPhone 6s onwards.

Yes. Cleana is available in 11 languages: English, Turkish, Spanish, French, German, Italian, Japanese, Portuguese, Russian, Simplified Chinese, and Arabic.

Cleana is free to download. Core duplicate detection and storage cleanup features are available to all users. Optional in-app purchases unlock premium features. There is no mandatory subscription.

Cleana uses perceptual hashing and AI-powered image analysis to compare every photo in your library. It identifies exact duplicates as well as near-duplicates taken seconds apart, so you can delete all redundant copies and keep just one.

Yes. Cleana detects visually similar photos, shots taken in burst mode, consecutive frames from the same scene, or photos with slight differences in angle or lighting. It groups these clusters together so you can compare them and keep only the best one.

Cleana's AI analyzes sharpness, blur detection, exposure, composition, and face quality to score each photo in a group. The highest-scoring photo is recommended as the best to keep; the others are flagged for deletion. You always have final say.

Cleana's AI achieves high accuracy by analyzing sharpness, blur, exposure, faces, and composition simultaneously. The model is designed to match human judgment in most cases. You can always override any recommendation.

Cleana's AI evaluates each photo across multiple dimensions: sharpness (blur detection), exposure and brightness, composition, face quality, and noise level. These scores are combined to rank photos within each similar group, so the clearest and best-composed photo is recommended to keep.

Yes. Cleana has a dedicated Large Videos feature that lists your biggest video files sorted by size. This makes it easy to find and delete the videos that are taking up the most storage space.

Cleana helps you identify large videos for deletion or management. For freeing storage, deleting redundant copies is the fastest approach since it recovers significant space without any quality trade-off.

Cleana can identify and help you remove: duplicate photos, similar photos, duplicate screenshots, large video files, duplicate videos, and unnecessary files that are taking up storage space on your iPhone.

The amount of storage you can reclaim depends on your photo library. Users with large libraries often free up several gigabytes, sometimes 10 GB or more, by removing duplicate photos, similar shots, and large videos they no longer need.

Yes. When iPhone storage is nearly full, iOS performance can degrade. The system needs free space for temporary files and smooth operation. Freeing up several gigabytes with Cleana can noticeably improve your iPhone's speed and responsiveness.
