Privacy

Updated 12 November 2026

The short version: the Prismaphone app collects no personal data. No account, no ads, no tracking. The app makes all its sound on your iPhone. It sends us a few anonymous counts, such as how far people get in the introduction and how long they play, with nothing that could tell us who you are. If you join the waitlist on this website, we keep your email address for it.

Who is responsible

The controller for the personal data described in this policy is RapidRocket GmbH, Rämistrasse 2, 8001 Zürich, Switzerland. You can reach us at hello@prismaphone.com.

This policy follows the Swiss Federal Act on Data Protection (FADP), for people in the EU and the EEA the General Data Protection Regulation (GDPR), and for people in the United Kingdom the UK GDPR.

In the app

No account, no third parties

Prismaphone has no account and no sign-in. It contains no advertising, no third-party analytics and no crash-reporting SDKs, and sends nothing to anyone but us. It doesn't need an internet connection to play.

Anonymous counts

To learn where Prismaphone is hard to understand and what people enjoy, the app counts a few things and sends them to us when you leave it: which pages of the introduction and steps of the tour were shown, whether the subscription page was seen and a plan chosen or bought, how long the app was open, and for each world how long you played and for how many seconds you used each move (tilting, leaning, sweeping, shaking).

The counts carry no name, no account, no device or advertising identifier, and nothing is stored on your iPhone for them, so we can't tell whose they are or link two visits. They never contain the sound, your touches or the motion itself. With them we keep only the minute they arrived and the app's version. They are received and stored by Vercel in Frankfurt, Germany, and used only to improve Prismaphone.

Like any request to this website, sending them needs your IP address. Vercel uses it to deliver the counts and to protect the service, and keeps a short request log with the time, the country the request came from and the app's and iOS version (see On this website). We don't store your IP address with the counts and don't use it.

Motion

While you play, Prismaphone reads your iPhone's motion sensors, how you tilt and move it, to shape the sound and the light. These readings are used on the device in the moment. They are never stored and never sent; the anonymous counts only say for how many seconds a move was used.

Recordings

If you record what you play, Prismaphone makes the video and the sound on your iPhone and keeps them in a temporary folder there. They stay on your iPhone unless you save or share them yourself. Saving a video to Photos asks for your permission to add to your library; Prismaphone can only add, it can't see your photos. When you close the recording, the temporary files are deleted.

Settings

The app keeps its settings on your iPhone. Deleting Prismaphone removes everything it stored there.

Subscription

Prismaphone's subscription is sold by Apple through the App Store. Apple processes the payment; we don't receive your payment details or your Apple ID. The app asks Apple on your iPhone whether your subscription is active. Apart from the anonymous counts (whether a plan was chosen or bought), it sends us nothing about it. Apple's handling of your data is described in Apple's privacy policy. If you have chosen to share analytics with app developers in your iPhone's settings, Apple may share anonymous crash reports and usage statistics with us.

On this website

prismaphone.com uses no cookies, no analytics and no tracking, and loads nothing from other sites. It is hosted by Vercel. To deliver the site and protect it from abuse, Vercel processes your IP address and basic technical information, such as your browser and the page requested, in its server logs.

The waitlist (optional)

If you join the waitlist, your email address is stored by Buttondown, the service that sends our emails, together with the date and the page you signed up on. Buttondown is based in the United States and checks new sign-ups for abuse, which uses technical data such as your IP address. You first get one email to confirm your address; nothing else is sent until you confirm.

After that, we write when Prismaphone is in the App Store and, now and then, about news and new worlds. Every email has a link to unsubscribe. To have your address deleted entirely, email hello@prismaphone.com.

When you email us

If you write to us, we use your email address and your message only to reply, and keep them only as long as needed for that. Our email runs on Google Workspace.

Creators we contact

To find creators who might like Prismaphone, we look at public profiles on YouTube, Instagram and TikTok. We note your public name or handle, the platform, your public follower count, your country and language, and why we think your content fits. We use this only to contact you once about a collaboration. If you don't take part, we delete it six months after our launch at the latest. You can ask us to delete it any time at hello@prismaphone.com. Legal basis: our legitimate interest in finding partners for our launch (Art. 6(1)(f) GDPR and UK GDPR).

Service providers

Some of these providers process data in the United States. Such transfers rely on safeguards such as the EU Standard Contractual Clauses or the EU–US and Swiss–US Data Privacy Frameworks, as set out in each provider's terms.

Legal bases

Where the GDPR or the UK GDPR applies, the server logs and your emails are processed for our legitimate interests in running a secure website and answering you (Art. 6(1)(f) GDPR and UK GDPR). The waitlist rests on your consent (Art. 6(1)(a) GDPR and UK GDPR), which you can withdraw at any time by unsubscribing. The app's anonymous counts are not personal data; where they could be, such as your IP address while Vercel delivers them, they rest on our legitimate interest in improving the app (Art. 6(1)(f) GDPR and UK GDPR). Notes on creators rest on our legitimate interest in finding partners for our launch (Art. 6(1)(f) GDPR and UK GDPR).

How long we keep data

Server logs are kept by Vercel for a short time under its policies. Emails are kept as long as needed to help you. Waitlist addresses are kept until you unsubscribe or ask us to delete them. Subscription records are kept by Apple under Apple's policies. The app's anonymous counts are kept as long as they help us improve the app. Notes on a creator who doesn't take part are deleted six months after our launch at the latest; if we work together, twelve months after the collaboration ends.

Your rights

You have the right to access your personal data, to have it corrected or deleted, to restrict or object to its processing and to receive it in a portable format. To use any of these rights, email hello@prismaphone.com. You can also complain to a data protection authority: in Switzerland the Federal Data Protection and Information Commissioner (FDPIC), in the EU the authority of the country where you live or work, and in the United Kingdom the Information Commission (formerly the Information Commissioner's Office, ICO).

Children

Prismaphone works the same for everyone: no account, no ads, no chat, no tracking. It collects no personal data from anyone, children included; the anonymous counts say nothing about who plays. Subscriptions are made by the holder of the Apple ID through Apple.

Changes

If we change how Prismaphone handles data, we'll update this policy and the date at the top.
