Privacy policy

The short version

Dancing Files does not collect anything about you. There is no account, no analytics, no crash reporting and no telemetry of any kind. Your files are converted on your own Mac and never leave it.

The app makes two kinds of network request and no others: it asks this site whether a newer version exists, which you can turn off, and — once you have bought it — it asks Lemon Squeezy whether your licence key is still valid. Neither one carries anything about you or your files.

Your files

Files you drop into the app are read from where they already sit, and the converted result is written next to them or to the folder you chose. Nothing is uploaded, and no copy is kept anywhere else. Playing an audio file before converting it plays it from that same place. With the network off, converting works exactly as it does with it on — a bought licence keeps working offline for a fortnight at a time, and the trial needs no network at all.

What is stored on your Mac

Two small files in ~/Library/Application Support/Dancing Files:

• settings.json — your preferences: the output folder, naming rules, theme, accent colour and whether the update check is on.
• history.json — the conversion log: file names, the formats, both sizes and the time. It is what the History view shows, and it clears from there or from Settings.

Both stay on your Mac. Neither is sent anywhere, and deleting the app's support folder removes both for good.

If you have bought the app there is also license.dat in the same folder — your licence key and the identifier of this Mac's activation, encrypted with a key held in your login Keychain. Alongside it, the Keychain holds the date the trial started, so that reinstalling the app does not quietly hand out another fifteen days. Neither contains anything about you beyond the key you were emailed.

The update check

A few times a day, and whenever you pick Check for Updates…, the app fetches a small file from this site called version.json. It holds nothing but a version number, a download link and a line about what changed.

The request carries no information about you, your Mac or your files — no identifier, no name, no count of anything. As with any request to any website, the server that answers it necessarily sees the IP address it is answering, which is how the internet works rather than something the app chooses to send.

Turn the check off under Settings › Updates and the app never contacts this site again. On the trial that leaves it making no network requests at all; once you have activated a licence, the check below is the only one left.

The licence check

This applies only if you have bought the app. Payment is handled entirely by Lemon Squeezy, who are the merchant of record: they take the payment, hold the receipt and issue the licence key. Dancing Files has no card field, never sees a card, and keeps no customer list — it has no way to know who you are.

To confirm a key is valid, the app sends the key and the name of this Mac to api.lemonsqueezy.com — on activation, then roughly once a day while the app is running, and when you press Check License. The name of the Mac is sent so that the two activations a licence allows are recognisable to you when you want to move one; it is whatever your Mac is already called. Nothing about your files, your conversions or your settings is ever part of it.

What Lemon Squeezy does with the data you gave them at checkout is covered by their privacy policy.

This website

dancingfiles.com is a handful of static files. There are no cookies, no trackers and no analytics scripts. The site is served by a hosting provider that, like every web server, keeps ordinary access logs — a request, a time, an IP address — which are used to run the service and nothing else.

Two things on the page come from somewhere else. Both belong to the pricing section, and neither carries anything about you:

• Lemon Squeezy's checkout script, which opens the payment window over the page when you press the buy button. Block it and the button still works as an ordinary link.
• The European Central Bank's daily exchange rates, read through frankfurter.dev, so the dollar figure beside the price is today's rather than last year's. The request asks for one rate and sends nothing else; the answer is kept in your own browser for twelve hours, so most visits do not make it at all. Block it and the figure printed in the page stands.

Children, and data requests

Since nothing about anybody is collected, there is nothing held about children specifically, and no data to hand over, correct or delete on request. If you want everything the app has ever stored gone, delete the app's support folder as described above.

If you have bought the app, your purchase does exist — at Lemon Squeezy, not here. Since they are the merchant of record and hold the only copy, a request to see, correct or delete it goes to them.

If this changes

Any future version that collects anything at all would say so here, with the date below changed, and it would say so in the app before doing it. There are no plans for that.
