Ampelino measures the volume directly on your device. Nothing is recorded, stored, or sent, not even when children are talking nearby. Something leaves your device in only two places: RevenueCat checks your Ampelino Pro purchase with a random ID and receives information about the trial, the purchase screen, and the introduction, never audio or measurements. With Pro, your profiles and design sync through your private iCloud. No account, no advertising, no tracking.

Ampelino uses the microphone only to measure the volume in the room. On your device, the signal is continuously turned into a single volume value, and the audio itself is discarded immediately. No recording is made, and none of it is stored or sent.

The app does not recognize voices or words. Even when children are talking nearby, no data about them is collected.

The app does not need an account. Your settings (e.g., limits, profiles, sensitivity, and design) are stored on your device. The app contains no advertising and no tracking.

Notifications, such as the notice that measuring continues in the background, are created locally on your device; no server is involved. If you turn on the settings lock, iOS handles Face ID or Touch ID entirely. The app only learns whether the check was successful and has no access to your biometric data.

With Ampelino Pro, your profiles and the selected design sync between your devices with the same Apple ID through your private iCloud key-value storage at Apple. Nothing else is stored there. Apple processes this data in accordance with its privacy policy; we have no access to it.

You can try Ampelino for free for 3 hours of measuring time; after that, Ampelino Pro is a one-time in-app purchase, and Apple handles the payment. To check whether Ampelino Pro is unlocked on your devices, the app uses the service RevenueCat, also when you have not bought anything. RevenueCat receives a random App User ID that is not linked to your name or Apple ID, information about your purchases (e.g., product, date, and App Store transaction), and technical device information (e.g., app version, operating system version, and App Store country). As with any internet connection, your IP address is transmitted for technical reasons.

For the trial, the app transmits when it started and ended, how many minutes have been measured (in total and per calendar day on this device), on how many days and when it was last used, since when the app has been locked, and whether purchases are possible on the device.

For the purchase screen, the app transmits where and how often it was opened (e.g., from the timer or after the trial), whether it could show a price, how often a purchase was started, how the last attempt ended (bought, cancelled, pending, or failed), and from where the purchase was started. This shows us which features lead to a purchase and whether purchasing works.

When you first open the app, it asks where you use Ampelino (daycare, primary school, or secondary school). This answer is transmitted as well, so we can see where Ampelino is used. The app also transmits which page of the introduction was shown last and how you finished it (purchase, restore, free start, completion, or skip), so we can improve the introduction.

Audio, noise levels, and your settings are never transmitted. The data is not used for advertising and is not combined with data from other apps or websites (no tracking).

You get the app through the Apple App Store. Apple is responsible for download, payment, and updates; we have no access to that data. Apple's privacy policy applies: https://www.apple.com/legal/privacy/

If you have turned on "Share with App Developers" in the iOS settings, Apple provides us with anonymous crash reports and usage statistics. They do not identify you.

The provider is RevenueCat, Inc., 1032 E Brandon Blvd #3003, Brandon, FL 33511, USA. RevenueCat processes the data on our behalf (Art. 28 GDPR). Because the data reaches the USA, the transfer is safeguarded by the European Commission's Standard Contractual Clauses (Art. 46(2)(c) GDPR).

Whatever happens only on your device or in your private iCloud does not reach us; we do not process that data.

Checking and restoring your purchases via RevenueCat is based on Art. 6(1)(b) GDPR (performance of the purchase contract). That the app also checks the unlock status when you have not bought anything, and that your IP address is transmitted for technical reasons, is based on Art. 6(1)(f) GDPR; our legitimate interest is a reliable unlock on all your devices.

Transmitting your answer about where you use Ampelino and the information about the trial, the purchase screen, and the introduction is based on Art. 6(1)(f) GDPR; our legitimate interest is understanding in which settings Ampelino is used, sizing the trial fairly, improving the introduction, and noticing when purchasing fails.

If you e-mail us, we process your address and message to answer you (Art. 6(1)(b) GDPR for questions about a purchase, otherwise Art. 6(1)(f) GDPR).

What the app stores on your device stays there until you delete it in the app or remove the app. Data in your iCloud can be deleted in your device's iCloud settings.

RevenueCat keeps purchase data as long as it is needed to manage your purchases; on request, we have it deleted unless statutory retention obligations apply.

RevenueCat keeps the information about the trial, the purchase screen, the introduction, and where you use Ampelino together with the random App User ID for as long as we need it for this evaluation; on request, we have it deleted.

We delete e-mails to us once your request has been resolved, unless statutory retention obligations apply.

You have the right to access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20), and to object to processing based on legitimate interests (Art. 21). You can withdraw consent at any time with effect for the future (Art. 7(3)).

Since we do not keep accounts and the app does not identify you, we often cannot attribute data to a person (Art. 11 GDPR). Write to us anyway; we are happy to help.

You can lodge a complaint with a data protection supervisory authority (Art. 77 GDPR), for example the one responsible for us: the data protection authority of Lower Saxony (LfD Niedersachsen), Prinzenstraße 5, 30159 Hannover, Germany, https://www.lfd.niedersachsen.de
