Backup, answered
The simplest iCloud alternative is a hardware backup device: plug Qubii between your phone and its charger, and photos, videos and contacts copy to a microSD card automatically — no cloud account, no Wi-Fi, no subscription. One-time prices start at $54.99, and backups restore to any new phone.
| Device | Storage | Best for | From |
|---|---|---|---|
| Qubii Duo | Your microSD, up to 2TB | Automatic backup while charging | $54.99 |
| Qubii EX | Built-in memory, ready out of the box | Parents & gifts — no card to buy | $63.99 |
| Qubii Power | Your microSD, up to 2TB | 45W fast charging + backup in one | $89.99 |
| Piconizer 4 | Portable flash storage (MFi) | Freeing up iPhone space in one tap | $76.49 |
| Nukii | Encrypted USB drive (AES-256) | Sensitive files, tap-to-unlock | $49.99 |
Plug a Qubii between your phone and the charger you already own — that's the whole backup. Every time your phone charges, new photos, videos and contacts copy to a microSD card in your hand, with no cloud account, no Wi-Fi and no monthly subscription. Set it up once with the Qubii app and it runs on its own; the card holds up to 2TB, enough for years of photos. Because the backup is physical, restoring is just as simple: plug the cube into your new phone and bring everything across, even when you switch between iPhone and Android. There is no account to create and nothing to remember — the charging habit you already have does the work. Prices start at $54.99 one-time — less than a year of most cloud storage plans — and over 1.2 million devices already keep memories safe this way.
All three back up your phone automatically while it charges; the difference is how storage and power are packaged. Qubii Duo ($54.99) is the thumb-sized cube: slide in your own microSD card, up to 2TB, and it quietly copies photos, videos and contacts each time you plug in. Qubii Power ($89.99) builds the same backup into a 45W fast charger, so one wall plug tops up your battery and your memories at the same time — the pick for travel and nightstands. Qubii EX ($63.99) ships with memory built in, so it works straight out of the box with no card to buy — the easiest setup for parents and grandparents. Whichever you choose, everything stays local and private: your files never touch a cloud server, there is nothing to subscribe to, and your backup moves with you to every next phone.
A local backup removes the attack surface entirely: your photos live on a card in your hand, not on a server that can be breached, scraped for AI training, or repriced next quarter. Cloud accounts fail in familiar ways — leaked passwords, changed terms of service, subscriptions that lapse and take your library with them. Hardware doesn't have those failure modes: a Qubii backup works with no internet connection at all, and Nukii adds hardware AES-256 encryption with tap-to-unlock for the files you carry between machines. That's why Maktar's line is built around ownership — pay once, hold your data physically, and decide for yourself who ever sees it. For sensitive libraries, pair automatic Qubii backups with an encrypted Nukii copy: two locations, both offline, both answerable only to you — and neither one carries a renewal date, a login page, or someone else's terms of service.
