Terms of Service

One purchase, no renewal

The full version is a single purchase of US$14.99 through the App Store. It does not renew, and it does not expire. Family Sharing is supported for up to six family members.

Refunds

Refunds are handled by Apple, not by us. Request one through your App Store purchase history — we have no ability to issue or decline it, and no record of your purchase beyond what the App Store tells the app.

What the almanac content is

The almanac layer takes the source text it declares as its reference; the in-app sources page states which parts of its data have not yet been checked against that text. It reproduces a tradition; it does not assert that the tradition predicts anything.

Almanac notes are cultural reference only. They are not medical, legal, financial or any other professional advice.

Accuracy and its limits

Astronomical values — lunar dates, solar terms, moon phases, sunrise and sunset — are computed. Lunar dates and solar-term dates were compared day by day with the Hong Kong Observatory’s published tables for 1901–2100; moon phases, sunrise and sunset were not compared with them. Outside that range the app declines to answer rather than guess.

Almanac notes are a different kind of thing: different almanacs follow different source texts and disagree with one another. Where this app differs from a printed almanac you own, that is expected.

Your data is yours

We claim no rights over the events, reminders or settings you create. They never leave your device unless you export them yourself.

Changes to these terms

If these terms change materially, the effective date at the top of this page changes with them.
