Paying for it
Cadence is free. Every module, every screen and the export that gets
your data back out work on one device without paying anything, and
that is not a trial — it does not expire, and nothing is withheld
behind a countdown.
One thing inside the app is sold: iCloud sync, which keeps the same
data on more than one device and is what sharing is built on. It
costs $14.99, paid once. The Mac and iPhone versions are
one app rather than two, so that single purchase covers both. There
is no subscription, nothing else to buy, and no charge for later
versions.
The sale is Apple's: Apple takes the payment, issues the receipt and
sets the price in your own currency, which will not be an exact
conversion. The developer never sees your payment details. If you
reinstall the app or move to another device, Restore Purchases in
Settings puts the unlock back at no further cost.
Sync being off, whether because it has not been bought or because
you switched it off, changes nothing about the data already on the
device. It stays where it is, in full, and stays exportable.
Refunds
Refunds are handled by Apple, not by the developer, through
reportaproblem.apple.com.
The developer cannot issue, approve or refuse one, and has no way to
reverse a purchase on your behalf.
Any statutory right to cancel that applies where you live is
unaffected by this page.
Sold as seen
Cadence is provided as it is, without warranty of any kind, express
or implied — including any implied warranty that it is fit for a
particular purpose or that it will run uninterrupted or without
fault. It is written by one person, and it has bugs in it that
neither of us has found yet — paying for it does not change that,
and is not a support contract.
Some places do not allow those exclusions, in which case they apply
to you only as far as the law there allows.
Where responsibility stops
To the extent the law permits, the developer is not liable for lost
data, lost time, lost money or any indirect or consequential loss
arising from using Cadence — including anything that follows from a
reminder that did not fire, a sync that did not run, or a record
that went missing.
Nothing here limits liability for anything that cannot lawfully be
limited.
It may change, or stop
Features may be added, altered or removed between versions; the
changelog records what actually shipped.
The app may one day stop being updated altogether.
If that happens, the copy on your device keeps working for as long
as the operating system supports it, and your export still produces
a plain JSON file that does not need Cadence to be readable.
