What the company does

One consumer app, owned outright

The holding does not license someone else's product. The app is ours: the code, the store listing, the release schedule and the support queue sit inside the company.

Free download, free account

The app is published on Google Play for Android. A visitor downloads it, creates a free account and uses the core features from the first screen — nothing is unlocked by a sales call.

Account settings stay in the app

Profile, notifications, sign-in and deletion of the account are all handled inside the app itself. No separate portal, no form to fill in, no ticket to open for a setting.

One entity answers for it

Publisher, operator and data controller are the same company. Enquiries about the app, its data handling or a partnership arrive at the people who ship it.

Write to the company

Business, press, partnership or data enquiries about the app we operate — leave your name and email and we come back to you.

  • Your message reaches the team that publishes and maintains the app, not an external call centre.
  • The first reply tells you who is handling it and what, if anything, we need from you.
  • If the matter concerns your own account, say so and we will point you to the setting in the app instead.
