KréyoLabs Key backs up, frees up space and optimises your Android phone. One USB drive, no cloud, no tracking. Plug it in and go.
One complete tool that replaces 5 apps. No cloud, no account, no subscription.
Caches, large old files, messaging media (WhatsApp, Telegram, Signal). Every file is identified, with a preview before deletion.
Photos, videos, documents, WhatsApp, Telegram, Signal. Everything is backed up with MD5 integrity checking.
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.
Your backed up files are laid out as an HTML gallery: filters, search, month-by-month timeline, built-in viewer.
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.
No data ever leaves your computer. No cloud, no account, no tracking. Everything stays between you and your USB drive.
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.
Insert the USB drive into your PC (Linux or Windows). Launch KréyoLabs Key in one click.
Plug your Android in over USB. The assistant walks you through enabling USB debugging.
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.
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.
Almost certainly: KréyoLabs Key works with the vast majority of Android phones. Check yours, or read the three markers below.
Any phone running Android 8 or later that allows USB debugging — that is, the vast majority of models in use.
Step-by-step assistant for Samsung, Xiaomi/Redmi, Huawei, Oppo, OnePlus and Google Pixel.
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.
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.
No data travels over the internet. Everything happens between your PC and your phone.
Nothing to install on your PC or your phone. The drive holds everything you need.
Android 8 and later, with USB debugging. Guided assistant for Samsung, Xiaomi, Huawei, Oppo, Pixel and OnePlus.
The same drive works on both systems. Double-click and go.
