Ritmik is a rhythm notation app by Studio Scale. This policy explains what happens to your information when you use it. The short version: your rhythms stay with you. We collect nothing personal unless you choose to send us a worksheet, and you can switch off the anonymous usage statistics at any time.
No account, no sign-up
Ritmik has no user accounts. You never give us your name, email address, or any other personal details to use the app. The one exception is entirely your choice: if you send us a worksheet for the library, you type the name you want credited — see "Sending us a worksheet" below.
Your rhythms stay on your device and in your iCloud
The rhythms you create, your folders, favorites, and settings are stored on your device. If you are signed in to iCloud, iOS also keeps a copy in your personal iCloud storage so your library can sync between your devices. That copy lives inside your Apple account — we cannot see, access, or recover your rhythms. Nothing you write leaves your device unless you send it: sharing a PDF, sharing a link, or submitting a worksheet.
Deleting the app deletes your data. We have no copy to delete on our side.
Purchases
Ritmik Pro subscriptions are processed entirely by Apple through the App Store. We never see or store your payment details. The app only learns whether your device has an active subscription, so it can unlock Pro features. Purchases can be managed or cancelled anytime in your Apple account settings.
Anonymous usage statistics
To understand which parts of Ritmik are actually used — and so decide what to improve next — the app sends anonymous usage statistics. You can turn this off at any time in Profile → Anonymous usage data. When it is off, nothing is sent.
What is sent: the fact that an event happened, plus a few non-identifying details about it. For example: the app was opened; a document was opened, and whether it came from the library or from your own files; playback started, and for how many seconds; which instrument was involved (bendir, erbane, handpan); which library rhythm was opened; a PDF was exported; the app's language; whether the device is an iPhone or an iPad; and whether the subscription is free or Pro. Counts of documents or measures are sent only as ranges (for example "3–5", "11–25"), never as exact numbers.
What is never sent in these statistics: your name, email address, or any contact details; the titles of your documents; the content of your rhythms; your files, PDFs, or folder names; your location; your IP address is not used to build a profile of you; your device's advertising identifier; or any Apple identifier.
How you are counted: so that repeat visits can be told apart from new ones, the app creates a random identifier the first time it runs, stores it on your device, and sends it in a scrambled (hashed) form. It is not derived from you, your device, or your Apple account, and it cannot be linked back to you. Deleting the app erases it.
Who processes it: these statistics are processed on our behalf by TelemetryDeck (TelemetryDeck GmbH, Germany), a privacy-focused analytics service. The data is stored on servers in the European Union. TelemetryDeck does not sell data and does not use it for advertising.
No tracking, no ads: Ritmik contains no advertising and does not track you across other apps or websites. We do not build profiles, and we do not sell or share your information. In Apple's terms, the data we collect is "not linked to you" and is "not used for tracking".
PDF export and sharing
When you export a rhythm as a PDF, the file is created on your device. Where it goes is entirely up to you, through the standard iOS share sheet.
Sending us a worksheet
Ritmik lets you send a worksheet you have written for possible publication in the app's library. This only ever happens when you choose it, fill in the form and tick the consent box.
What is sent: the worksheet itself as a PDF; the name you type to be credited with it; the instrument, your app language and app version; and the wording of the consent you agreed to.
If you leave your email address: it is optional — we use it only to reply to you and to send your free week of Pro, and we delete it once that is done. Leave it blank and we simply can't reply or gift you the pro.
Where it goes: to storage we run at Cloudflare (Cloudflare, Inc.), and a notification email to us. It is used to review the submission and, if we publish it, to credit you in the library. It is never sold, never used for advertising, and never added to any profile of you.
How long we keep it: until we have reviewed it, and — if it is published — for as long as it is in the library, so that we can keep crediting you. If we do not publish it, we delete it.
Changing your mind: write to us at https://studioscale.co/apps/contact and we will remove your worksheet from the library and delete the copy we hold.
Children
Ritmik is suitable for all ages. We collect no personal data from anyone, including children, unless a worksheet is deliberately sent to us with a name on it. The anonymous usage statistics described above contain nothing that identifies a person, and they can be switched off in the app.
Your rights
Unless you have sent us a worksheet, we hold no personal data about you, so there is nothing for us to look up, correct, or delete on request. If you have sent one, write to us and we will show you what we hold, correct the name, or delete it. If you would prefer that Ritmik sends no usage statistics at all, switch off Profile → Anonymous usage data; the app stops sending them immediately.
Changes to this policy
If Ritmik ever changes in a way that affects your privacy — for example, if we add accounts or online features — we will update this page and the effective date above before the change ships.
