Last updated: August 2026 — this policy applies to the iOS app Neuron only. The website has its own privacy policy; so do the other apps, Interim and Tide.

Neuron is a self-contained app with no user account and no registration. Everything you record in the app is stored exclusively on your own device.
The app contains no code for network connections, no analytics or tracking libraries, no advertising networks and no third-party libraries. There is no server of ours that data could be sent to.
It follows that we receive no personal data from your use of Neuron. To that extent no processing by us takes place; the data remains in your hands and under your control.
Your training results and scores, your daily statistics, your streak and settings such as the language you have chosen (German or English).
This information is kept in a shared app container on your device so that widgets can display the same values. The container is managed by iOS and does not leave the device.
Neuron does not access Apple Health and does not process any health data. The app requests no Health permission at all. Your training results are game scores, not medical information, and they are not evaluated as such.
If you would like them, Neuron reminds you about your daily training. These notifications are scheduled locally on your device; there are no push servers and no device identifiers that would be transmitted to us. The legal basis is your consent given through the iOS dialogue (Art. 6(1)(a) GDPR), which you can withdraw at any time in the iOS Settings.
Your streak and daily progress can be shown as a widget on the Home Screen. The values come from the local app container on the same device and are not transmitted anywhere.
Neuron includes an optional tipping feature. Payment is handled exclusively by Apple; we receive neither your payment details nor your name, only aggregated sales reports from Apple that contain no personal reference.
Apple is responsible for download, purchase and billing in the App Store. If you use your device's iCloud backup, it may also cover app data; Apple's privacy policy applies to that. We have access to neither.
If you remove Neuron from your device, the associated local data is removed with it.
You are reading this page over the internet. It is hosted by Vercel Inc., 340 S Lemon Ave #4133, Walnut, CA 91789, USA, and server log files are created in the process (IP address, time of access, page requested, volume of data transferred, referrer, browser, operating system). The legal basis is Art. 6(1)(f) GDPR. A data processing agreement under Art. 28 GDPR is in place with Vercel; the transfer to the USA is based on the European Commission's standard contractual clauses and on Vercel's certification under the EU-US Data Privacy Framework. The website privacy policy sets this out in full.
Automated decision-making, including profiling (Art. 22 GDPR), does not take place. You are under no statutory or contractual obligation to provide us with personal data. The only recipients of data are our hosting provider Vercel as a processor and — for downloads and tips — Apple as a separate controller.
You have the right of access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and objection (Art. 21 GDPR). Consent you have given — for notifications, for example — can be withdrawn at any time with effect for the future in the iOS Settings. You also have the right to lodge a complaint with a data protection supervisory authority (Art. 77 GDPR). The authority responsible for us is: Der Landesbeauftragte für den Datenschutz Niedersachsen (State Commissioner for Data Protection of Lower Saxony), Prinzenstraße 5, 30159 Hannover, Germany, www.lfd.niedersachsen.de.
Right to object: where we process data on the basis of Art. 6(1)(f) GDPR, you may object at any time on grounds relating to your particular situation (Art. 21 GDPR).
For any request concerning your rights, please write to app@goswami.de.
We update this policy when the app or the legal situation changes. The version published here is the one that applies.
This English text is a translation of the German original, which is the legally binding version. We have translated it carefully rather than mechanically — if you spot a passage where the two differ in substance, please tell us at app@goswami.de and we will correct it.
