What we are exploring

Topics we explore

Alexandra reads the AI research so you don't have to, and shares it as short videos and posts on her channel. These are the three topics it keeps coming back to.

AI research so you don't have to read it

Papers and benchmarks boiled down: how AI changes the way we think, which model to use, what it really costs, and the week's news without the hype.

Founders diary

Building Crocodata next to a full-time job: the hours nobody talks about, lessons from other founders, the design calls behind our website and apps, and what we had to unlearn.

FAQ

Frequently asked questions

What does Crocodata do?

Crocodata sp. z o.o. is an independent tech studio registered in Warsaw, Poland. We build and publish our own consumer mobile apps for Android and iOS. Legal notice

How do the apps make money?

CleanFotos and AppSwipe are free with ads, and a one-off Pro purchase removes them. Askra is free with optional rewarded ads and a paid subscription. FotoPost will sell physical photo prints. Nothing is funded by selling your data.

What happens to my data?

Wherever it is technically possible, nothing leaves your device — CleanFotos and AppSwipe analyse everything locally. Askra and FotoPost need a server to work, and both document exactly what is sent and for how long it is kept. Every app has a privacy policy and a data-deletion page. See our privacy overview.
