Sumon Enterprise is an independent Android software publisher. We build small, focused, offline-first tools for people who do unpaid work — coaches, organisers, volunteers. No accounts, no analytics, no servers holding your data.
No data collected · No ads · No subscriptionsEverything we publish on Google Play is listed here, under the developer name Sumon Enterprise.
Offline squad rotation & playing-time tracker. A live match clock that counts every player's minutes, plus fair-play stats, attendance, streaks and CSV export — built for volunteer coaches at grounds with no coverage.

We release rarely and maintain what we ship. New titles are announced on this page and published under the same developer account, with the same commitments: offline by default, no data collection, no advertising.

Four rules we apply to every app we publish. They are product decisions, not marketing — they are why our Google Play Data Safety declarations read "no data collected".
Our apps do their whole job with aeroplane mode on. No feature waits on a server, so nothing breaks in a car park or a village pitch.
Records live in the app's private storage on your device, encrypted where sensitive. We never receive them, so we can never lose, sell or leak them.
No sign-up, no analytics SDK, no advertising identifier, no crash reporting. You can use everything we make without telling us who you are.
No subscriptions, no in-app purchases, no ads. An app ships when it is complete, and then gets maintained rather than monetised.
Sumon Enterprise is the registered publisher behind the apps above. Full legal and contact details are on the about page; the essentials are here.
Our first app. Free, no ads, no in-app purchases, and fully usable with no connection.
