SIT Viewer Privacy Policy

Effective 13 September 2026

SIT Viewer collects no personal data. The app has no accounts, no registration and no analytics, and it sends us nothing about you or your phone.

What the app does not do

SIT Viewer contains no analytics, tracking, advertising or crash-reporting systems. No third party receives data from it, and we build no user profiles. The app's developer receives none of your video, none of your audio, none of your coordinates and no list of your devices.

What is kept on your phone

Everything below stays on the device and is never sent anywhere from it:

• Your device list — the name, serial number, server address and access token you entered yourself or took from a QR code.
• The device password, if you asked the app to remember it. It is stored separately, in the system's secure storage (Keychain on iOS, Keystore on Android), not alongside the other settings.
• Files you downloaded from a device, and recordings the phone made itself.
• App settings — the chosen language and small interface conveniences.

Deleting the app removes all of this from the phone.

Permissions, and what they are for

Microphone

Required on iOS only, and only to play a device's sound: the system routes it through the audio unit meant for calls, and that unit opens only when this permission is granted. The app does not record audio from your phone and does not transmit it — both media channels are receive-only.

Location

Used to show your own position on the map next to the device. It is read only while the map screen is open, is not stored, and is never transmitted. Without this permission the map still works — it simply has no dot for you.

Camera

Used only to scan a QR code when adding a device. The camera image is processed on the phone, is not stored and is not sent anywhere.

Photo library

Needed only if you save a downloaded recording into the phone's photo library. The app reads nothing from your library — it only adds a file there when you ask it to.

Where the app's data goes

SIT Viewer exchanges data only with the server whose address you entered — the server run by your organisation or your equipment supplier. Video, audio, device coordinates, device settings and files all travel through it. We do not operate that server, have no access to it and receive no data from it; its owner is responsible for it under their own rules.

The app opens no other connections.

Maps

The map is drawn by the phone itself: Apple Maps on iPhone and iPad, Google Maps on Android. Those components belong to Apple and Google and operate under their privacy policies. If you tap "Directions" or "Share", the device's coordinates pass to a maps app or to the messenger you chose — but only on that action of yours.

Children

The app is made for operators of professional equipment and is not directed at children. We knowingly collect data from no one, children included.

Changes to this policy

If the app ever handles data differently, we will update this page and change the date at the top. The version published here is the one in force.
