About Oson Studio

Who we are

Oson Studio is a platform of free online tools created to simplify everyday digital tasks. The site has been running since 2026 and is tailored to the needs of users in Uzbekistan: here you'll find document generators, calculators, keyboard games, qaza (missed worship) calculators and many other tools.

Technical features

Most of the tools run directly in your browser — which means:

• Your files are never uploaded anywhere. Images, videos, PDFs and other files are processed only on your device.
• Speed. Whether you have internet or not, the tools work almost instantly.
• Privacy. Because data is not sent to a server, it is not visible to us or anyone else.

Only a few tools (AI image enhancement, temporary email, certain libraries) use external services to work — more on this in the Privacy Policy.
