In short
knipper. does not collect personal data. The app has no server, no account, no sign-in and no analytics, tracking or advertising services. It does not connect to the internet itself; only the trial, the purchase and “Restore purchases” go through Apple’s App Store. As the provider I receive no data from you and have no access to your recordings.
What is stored on your iPhone
Your videos with sound, recording time and time zone, cassette names, descriptions, finished films, copies of the music you add to cassettes, your settings and – if you enter it – your name. Everything is kept only in the local app storage of your iPhone and is excluded from iCloud and device backups. It stays stored until you delete it in the app or remove the app.
Camera, microphone and Photos
Camera and microphone are only used for your recordings. knipper. only accesses Photos to add a clip or film when you save it there; your library is not read. If you pick the sound of a video from Photos for the music, iOS opens its own picker: the app only receives the one video you tap and only takes its sound track. You can change these permissions at any time in the iOS Settings under “knipper.”.
Sharing, backup and saving
Data only leaves your iPhone when you start it yourself: when you save a film through the iOS save dialog, send a shared cassette by AirDrop or USB stick, or create a backup on a USB stick. A shared cassette contains the clips with recording times, descriptions and your name, if entered, but no music. A backup also contains the music files. If you choose a cloud or messenger service, its privacy policy applies.
App Store and crash reports
Purchase, download, updates and the in-app purchase of the full version (also “Restore purchases”) go through Apple’s App Store. knipper. only learns whether the full version or the trial is unlocked on your Apple ID – no payment data. Apple processes data there under its own responsibility (Apple Privacy Policy). If you enabled “Share With App Developers” in the iOS Settings, Apple provides me with anonymized crash and diagnostic data. The legal basis is your consent (Art. 6(1)(a) GDPR), which you can withdraw there at any time.
Support by email
If you send me an email, for example through the support page, I process your email address, your name and the content of your message including attachments to answer your request. The legal basis is Art. 6(1)(b) GDPR where it concerns the use of the app, otherwise my legitimate interest in answering requests (Art. 6(1)(f) GDPR). I delete the message once your request is settled and no statutory retention obligations apply.
This website
For visiting this website, the general privacy policy of marvinvanbeek.de also applies, for example on hosting, server log files and cookies. The knipper. pages do not embed any further services of their own, so no form and no embedded videos. The link to the App Store only takes you to Apple after you click it; Apple’s privacy policy applies there.
Your rights
You have the right of access, rectification, erasure, restriction of processing, data portability and objection (Art. 15 to 21 GDPR) and to withdraw consent (Art. 7(3) GDPR). Just send me an email. You can also lodge a complaint with a data protection supervisory authority, for example the Bavarian Data Protection Authority (BayLDA), Promenade 18, 91522 Ansbach, Germany.
There is no automated decision-making or profiling. I do not transfer any data to third countries.
