Your photos and files stay private. Even from your cloud.

When you back up to Google Drive or OneDrive, the company storing your files has access to them. CipherNest changes that. It locks your files on your phone before they upload, so what reaches your cloud is scrambled data that only you can unlock. Google and Microsoft still store your files. They just can't open them.

You keep the cloud you already use. Nothing to move, and no extra storage to buy.

What you get:
- A proper gallery. Your photos and videos sorted by date, with albums, a full-screen viewer and a simple photo editor. It feels like the gallery you already know.
- Automatic backup. Choose which albums to back up and CipherNest takes care of it in the background, even while the app is locked.
- Folders for everything else. Keep documents, music and other files organised your way. Even the folder names stay private.
- Videos that play straight away. Watch videos from your cloud without downloading them first.
- Music and documents. Play your music and read PDFs right inside the app.
- Private sharing. Send someone a link to a file, and add a password for anything sensitive.
- More than one phone. Set it up on another device and everything stays in sync.
- A recycle bin. Deleted files wait 30 days before they're gone for good.
- Fingerprint unlock, and seven themes to choose from.

How it works:
When you set up CipherNest, it gives you 12 words. This is your recovery phrase, and it is the only key to your files. Write it down and keep it somewhere safe.

Your files are locked with that key on your phone, before anything is uploaded. The key never leaves your devices. There is no CipherNest account to create and no CipherNest server holding your data. There is nothing of yours to hand over to anyone, and no one else holds the key.

That comes with one honest warning. If you lose your recovery phrase, nobody can get your files back, not even CipherNest. That is the trade-off for this kind of privacy, and it is better to know it now than later.

Price:
Every feature is free for up to 1,000 files. CipherNest Plus removes the limit. If you ever stop paying, you keep full access to everything you've already stored. Your files are never held back.

Honest about the limits:
The source code is public, so anyone can check that the app does what it says. The app has been checked against a published industry standard for mobile app security. It has not yet been reviewed by an outside security firm.

A few other things worth knowing:
Android only for now but website version underway.
Works with Google Drive and OneDrive. More providers are planned.
Your cloud can still see how many files you have, how big they are and when they were added. It can't see what they are or what they're called.

CipherNest is made by one person, in the open.
