Apps that don't need the Internet.
And don't even ask for it.
An app that works on your data does not have to send it anywhere to do so. That is the principle behind everything published here, and it can be checked — below.
Proof, not a promise
"We respect your privacy" is a sentence everyone writes. It costs nothing and cannot be verified. Here is what can:
Klean does not declare the Internet permission. Android therefore makes it technically unable to reach any server — even if the code tried. That one missing line in the manifest says more than a page of policy.
The rest follows: no account to create, no ads, no analytics, no third-party service bundled in. This site does not watch you either — no script, no remote font, no tracker, and the server's logs are switched off.
- No data is sent anywhere
- No account, no sign-up
- No ads, no trackers
- Nothing runs on a server, so there is nothing to breach
Check it yourself
Three checks, no need to take our word for it.
Airplane mode
Turn it on, then use Klean: everything works exactly the same. Nothing in it ever depended on the network.
The data counter
In Android's settings, open the app's page on mobile data and Wi-Fi: the counter stays at zero.
The Google Play listing
"Full network access" is missing from the app's permissions, and the "Data safety" section states that no data is collected or shared.
Our principles
What every SBSoft app keeps to, without exception.
Offline by design
No Internet permission: the promise is kept by Android, not by our good will.
Nothing is collected
No account, no ads, no analytics, no crash report sent. Your data stays yours.
Nothing irreversible without you
An app that deletes asks first. And by default it goes through Android's trash, which keeps everything for 30 days.
For everyone
Android's font sizes respected, flows checked with TalkBack, and four languages: English, French, Spanish and German.
What is published
One app for now, and more on the way.
Klean
Your screenshots get an expiry date and go to the trash in one tap, restorable for 30 days.

Klean will soon learn to spot your duplicates. More apps will follow, on the same principle: useful, and without the Internet.
Frequently asked questions
Why apps without the Internet?
Because most apps do not need it for what they do. And data that never leaves your phone cannot leak from a server, be sold on, or be used to profile you.
What happens to my data?
It stays on your phone, inside the app. It is even excluded from Google backup: uninstalling the app erases all of it, and nobody else ever had a copy.
What if I change phones?
The app's settings and history do not follow you: that is the price of the promise, since they go through no server and no backup. Your photos are not affected: they stay in your gallery, which you transfer as usual.
How do I report a problem or suggest an idea?
By email, at contact@sbsoft.studio. It is the only channel: without a connection, the apps cannot send us anything on their own, not even a crash report.
