Everything your
phone needs

One complete tool that replaces 5 apps. No cloud, no account, no subscription.

Free up space

Caches, large old files, messaging media (WhatsApp, Telegram, Signal). Every file is identified, with a preview before deletion.

Full backup

Photos, videos, documents, WhatsApp, Telegram, Signal. Everything is backed up with MD5 integrity checking.

Video compression

Shrink your videos by 40 to 60% with H.265 compression, with visually preserved quality. The gain depends on the source format: a video already in H.265 will gain almost nothing.

Browsable gallery

Your backed up files are laid out as an HTML gallery: filters, search, month-by-month timeline, built-in viewer.

Bloatware manager

Spot and disable useless pre-installed apps. A database of 38 applications with risk levels, currently centred on Xiaomi/Redmi and growing as more models are tested.

Private data

No data ever leaves your computer. No cloud, no account, no tracking. Everything stays between you and your USB drive.

3 steps, an 8-minute diagnostic

No software to install. No account to create. The drive holds everything. The backup itself depends on how much there is to copy — count on about an hour for 40 GB.

1

Plug in the drive

Insert the USB drive into your PC (Linux or Windows). Launch KréyoLabs Key in one click.

2

Connect the phone

Plug your Android in over USB. The assistant walks you through enabling USB debugging.

3

Back up, then free up space

Follow the assistant step by step: diagnostic, backup, freeing up space, compression, report. Nothing is deleted before it has been backed up and verified — and the tool tells you how long it will take before starting.

It all fits on
a USB drive

🔐

Every drive is unique: tied to its licence, protected against copying, and ready to use. Works on Linux and Windows. Runs with no installation, no internet, no account.

Is your phone
compatible?

Almost certainly: KréyoLabs Key works with the vast majority of Android phones. Check yours, or read the three markers below.

The simple rule

Any phone running Android 8 or later that allows USB debugging — that is, the vast majority of models in use.

Guided brands

Step-by-step assistant for Samsung, Xiaomi/Redmi, Huawei, Oppo, OnePlus and Google Pixel.

Tested & verified

Verified in real conditions on Xiaomi / Redmi. The list of tested models grows with each release.

The core functions — diagnostic, backup, freeing up space, compression — are universal; some extras depend on the brand (e.g. bloatware removal). Unsure about your model? Write to us before ordering and we will check it with you.

A drive, not a subscription

Pay once, use it with no time limit. Compatibility updates included for 3 years.

The capacity of the drive changes nothing about what the software does — all three plans have exactly the same functions. It only decides what fits on the drive itself: one full phone at 128 GB, two at 256 GB. Your backups can just as well go on your computer or an external disk, as you prefer, and the tool checks the available room before starting rather than telling you after two hours of transfer.
