In short: OSC Bridge collects no personal data. It relays OSC messages between the devices you set up yourself on your own network. The app has no account, no analytics, no advertising and no tracking, and it sends nothing to us or to any internet service.
Who we are
OSC Bridge (“the app”) is developed by Raunoa OÜ, a company registered in Estonia (registry code 12304840), Tartu mnt 52-9, Iisaku alevik, Alutaguse vald, 41101 Ida-Viru maakond, Estonia. Email: rauno@raunoa.com.
What the app does with your data
The app forwards OSC messages between addresses that you enter. Everything happens on your Mac and your network:
- OSC messages are received on the ports you choose and sent only to the sources and targets you configure. They are not stored, except for the recent messages shown in the Log window, which are kept in memory and cleared when you quit.
- Settings — source and target names, IP addresses, ports and prefixes, and your startup preferences — are saved in the app’s own sandbox on your Mac so the bridge comes back the same way next time.
- The control window is served by the app itself on your Mac’s local loopback address (127.0.0.1). It is not reachable from the internet.
- Exported settings and logs are saved where you choose.
None of this information is sent to us or to anyone else. We cannot see, access or recover your settings or your traffic.
What we do not do
- No user accounts or sign-in.
- No analytics, telemetry or usage tracking inside the app.
- No advertising and no third-party SDKs.
- No connections to us or to any internet service: the app only exchanges OSC with the devices you configure.
- No access to your microphone, camera, contacts, location or photo library.
Local network permission
On recent versions of macOS the system asks whether OSC Bridge may find and connect to devices on your local network. The app needs this to send and receive OSC. You can change the choice at any time in System Settings → Privacy & Security → Local Network.
Apple and the App Store
The app is sold through Apple’s App Store. Apple processes your purchase, payment and download under Apple’s Privacy Policy; we do not receive your name, email or payment details.
Apple gives developers aggregated, anonymous statistics such as the number of downloads and sales per country. If you have chosen to share analytics with app developers in your device’s settings, Apple may also share anonymous crash reports with us, which we use only to fix bugs. You can turn this off at any time in System Settings → Privacy & Security → Analytics & Improvements.
Contacting us
If you email us for support, we use your email address and message only to answer you. If you send us a settings file or a log to look at, we use it only to investigate your question and delete it afterwards. We keep the correspondence as long as needed to help you and to meet our legal obligations, and we do not share it with third parties.
Your rights
Under the EU General Data Protection Regulation (GDPR) you have the right to ask what personal data we hold about you, and to have it corrected or deleted. Because the app collects no personal data, in practice this only concerns emails you have sent us. Write to rauno@raunoa.com. You also have the right to lodge a complaint with the Estonian Data Protection Inspectorate (Andmekaitse Inspektsioon) or with the data protection authority in your own country.
Children
The app does not collect personal data from anyone, including children.
Changes to this policy
If the way the app handles data ever changes, for example if a future version adds an online feature, we will update this page and the date above before that version is released.
