R17 PLAY · Apps from Graz

What leaves your device is your call.

Our apps compute on the device and work without a network. Recordings, audio and everything derived from them stay there — unless you explicitly send something. And when you do, you see it happen.

The boundary

One line decides everything

Privacy here is not a setting you have to hunt for, but an edge the code never crosses on its own — only you do. This is what it looks like.

Diagram of the device boundaryA device holding recordings, computed features, history and the encrypted database. To the left, the path for images, audio and features is blocked. To the right, two dashed paths lead out: one for advertising and crash reports, requiring consent, and one for individual analyses that only the user triggers, per action.YOUR DEVICERecordingsComputed featuresHistory and notesEncrypted databaseNever crossesImages · Audio · FeaturesOnly with consentAdvertising · Crash reportsasked first, revocable at any timeOnly when you trigger itindividual analysesper action, off by default

asked first, revocable at any time

Ads are served — but the ad SDK never sees your recordings, microphone data or computed features. That is enforced by construction, not by a promise.

In the catalogue

Our apps

Every app is listed here before it reaches the store — including its permissions and data flows.

The foundation

What is inside every R17 app

Four things we build once, properly — then every app inherits them. That is not a technical detail; it is why we do not have to weigh the same decisions again for every app.

  1. Consent first

    No advertising or analytics service starts before you have been asked. The order is fixed in code and cannot be configured — not even by accident.

  2. Deletion that actually deletes

    One function removes the database, files, caches and key material. An automated test then searches the entire app directory for leftovers.

  3. No account with us

    You sign up with us nowhere. A subscription runs through your Apple ID or Google account — where you already are. We keep no profile anyone could lose or hand over.

  4. Works offline

    Every feature runs without a network. A connection is an addition, never a prerequisite — on a train, in a basement, on a plane.

Verify

Do not trust us, read it

For every app you can read which permission it requests and what for — verbatim. The same sentence appears in the privacy policy, because both are generated from the same source as the app itself.

They cannot drift apart: a permission without a stated reason cannot be built in at all.

Got an app in mind?

We build for our own catalogue — and on commission for companies that need something of their own. From the idea to the store.
