Who is behind RosaCue

One developer, working alone, with rosacea.

The apps already available do one of two things. They sell products, which makes every finding suspect. Or they ask for an account, a cloud sync and far more data than the job needs — including photographs of your face.

RosaCue was built to do the narrow part properly instead: keep an honest diary, do the arithmetic on the device, and show every finding with its counter-evidence and its sample size. Nothing is recommended, because the log cannot support a recommendation.

The trade-off is deliberate. No account means nothing to breach, and it also means there is no sync — so the CSV export in Settings matters.
