Privacy policy

1. Private data collected

Mustud collects very little. Apple provides me with aggregate statistics about the app (app store impressions, downloads, sales, conversions). Mustud itself does not track what you do, and there is no analytics service inside the app. Nothing I receive can identify you as an individual.

1.1. Your worksheets

Worksheets are stored in files on your own device, or in your own iCloud Drive if you choose to. I can't see them, and they are never sent to me or to any third party.

1.2. Third Parties

The only third party Mustud uses is RevenueCat, for subscriptions (see section 3). There are no social logins, no advertising SDKs, and no third party data storage services.

1.3. Advertising

It doesn't exist within Mustud. I refuse to track you, or try to serve you personalised ads.

2. Accounts

Mustud does not have accounts. You don't sign up or log in. Your subscription is tied to your Apple Account, which Apple manages.

2.1. Transaction ID

To provide support, I may ask you to send me an ID so that I can find your purchase. If you're having trouble with unlocking features, or you won a competition, I can use this ID to help, for example by providing a free subscription.

3. Purchases and subscriptions

Mustud is free to download. Creating and editing worksheets requires a subscription, which is bought through the App Store. Payments are handled entirely by Apple. I never see your payment details.

To check whether your subscription is active, Mustud uses RevenueCat, a subscription service. RevenueCat receives an anonymous random ID generated by the app, your purchase and subscription status, and basic device and app information, such as the app version and your country. It does not receive your name, your email address, or anything you write in your worksheets.

If you bought Mustud before it became free, the app uses Apple's purchase record on your device to confirm this, and keeps every feature unlocked for you.

4. Analytics

Mustud uses no analytics services other than those provided by Apple. Apple shows me stats based on the usage of all apps, and never information on a single user: things like downloads, updates, purchases, revenue and retention.
