About this app

Your gallery has ten years in it. Somewhere in there are four hundred
screenshots you never look at, eleven takes of the same photo, and a
video you forgot you recorded.

Cerno shows you one at a time. Swipe left to trash it, right to keep it.
That is the whole app.

WHAT YOU SEE FIRST

Cerno opens straight into piles, already sorted — no setup, no
configuring, no waiting on a scan you have to sit through:

• Every month, so you can start with the year you have forgotten
• Screenshots, on their own, because they are almost never worth keeping
• Since your last cleanup, so returning takes seconds
• How much space each pile is actually using, before you open it

NOTHING IS DELETED WITHOUT YOU

There is no automatic clean, no schedule and no background deletion. You
see every photo and you decide on every photo. You can undo any swipe,
and nothing at all happens until you confirm the whole batch at the end.

Anything you do trash goes to your device's own trash, where Android keeps
it recoverable for 30 days.

YOUR PHOTOS DO NOT GO ANYWHERE

Everything happens on your phone. Reading your library, grouping it,
comparing photos to find near-identical ones — all of it, locally.

Cerno has no server and no account, so there is nowhere for your media
to be sent even in principle. It also never reads the GPS location
stored inside your photos: a cleaner has no business knowing where you
were.

PREMIUM — ONE PAYMENT

The free version cleans by month and by screenshots, with a daily limit,
and is supported by ads. One payment, no subscription, nothing expires:

• Unlimited daily cleaning
• Clean by folder — Camera, Download, Instagram, each on its own
• WhatsApp and Telegram media, which is usually the biggest pile on the
phone and the safest to clear
• Lookalikes — finds near-identical shots, keeps the sharpest, offers you
the rest
• Every video, largest first, where the space actually is
• Sort any pile: largest, smallest, oldest or newest first
• Protected folders — tell Cerno to never offer a folder, permanently
• Your stats — space freed, photos reviewed, what is left
• No ads

WHY IT IS CALLED CERNO

Latin, cernere: to sift, to separate, to decide. Which is the job.
Swipe to clean your gallery. Nothing is uploaded, nothing deleted without you.

• Landscape photos and videos now fill more of the screen

• Menus and pickers now follow the language you chose in Settings
• Home now says when photos and videos from the past week aren’t being offered yet
