What is HEPLANO?
HEPLANO is the umbrella brand for four independent product lines: apps and free calculators for trades and small business, a habit tracker for everyday life (HEPLANO Flow), and free random-picker and party games for groups with an optional app tournament mode (HEPLANO Loser). The product lines are content-wise independent of each other.
What apps does HEPLANO offer?
Currently HEPLANO Rechnung (invoicing for small businesses) and HEPLANO Build (job-site documentation). In addition there are HEPLANO Flow, a habit tracker, and HEPLANO Loser, a party-games app with an optional tournament mode – both are available for Android on Google Play. The related free web games work too.
Are the calculators on this website free?
Yes. All trade calculators and all random-picker and party games are free to use with no sign-up. The calculation or game runs directly in your browser – your input is never sent to a server.
How does HEPLANO handle my data?
The calculators on this website don't send any input to a server. How the individual apps handle data is described in each app's own privacy policy, linked from the privacy page.
Are the HEPLANO apps also available for iOS?
