Yau Our promise
These rules apply to every app we make. If we ever break one, tell us and we will put it right.
Useful first
We only make an app when it saves people real time or money. Every feature has to earn its place, and anything that gets in the way is left out.
Clear and simple
Large text, plain words and no clutter. We design with older users in mind, because when something is clear for them, it is clear for everyone.
No annoying ads
No pop-ups, no full-screen videos and no ads dressed up as something else. If an app ever shows an ad, it will be small, quiet and clearly marked. YauBus has no ads at all.
Your data stays yours
No tracking and no analytics that follow you around. We never sell or share personal data. Wherever we can, things like your location are used only on your phone.
No hidden costs
Free, or a clear price shown before you pay. No surprise subscriptions, no pay-to-unlock tricks and no small print.
Made for everyone
English, Traditional and Simplified Chinese, big text, high contrast and screen reader support, from the first version.
Something not right?
If any of our apps falls short of this promise, we want to hear about it.
