Effective date: [9 November 2026]
This Privacy Policy explains how the TunerView Pro mobile application („the app”) for iOS and Android
handles information.
1. Summary
- The app does not require an account and does not ask for your name, e-mail address or phone number.
- The app contains no advertising, no analytics and no tracking, and we do not sell any data.
- Engine data, logs, videos, dashboards and GPS data stay on your device, except when you start the
optional „Live stream” feature, or when you share something yourself.
2. Data processed only on your device
- Vehicle and engine data: read from your car’s engine control unit (ECU) through a Bluetooth,
Bluetooth LE, WiFi or USB adapter, to show the dashboard and to record data logs. - Location (GPS): used to show GPS speed, the GPS track, acceleration timing (e.g. 0–100 km/h) and lap
timing. Location is used only while you use these functions. If you enable „keep updating in the
background” for the Lock Screen / Live Activity, location may also be used in the background while
that Live Activity is running (iOS). - Motion sensors: the accelerometer is used for the G-force and pitch / roll gauges.
- Camera and microphone: used only in Camera mode to record a video with the dashboard overlay. Videos
are saved on your device / in your photo library at your request. - Data logs, dyno runs, lap times, dashboard layouts, images you add and settings are stored on your
device.
None of this is sent to us. When you use a share function (for example sharing a log, a layout or a
dyno chart), the file goes to the app or person you choose through your phone’s share menu; that
transfer is governed by the recipient service’s own privacy policy.
3. Live stream (optional subscription)
If you subscribe to Live stream and tap „Start streaming”, the app sends the following to our server
(linszter.net) over an encrypted connection (HTTPS) several times per second:
- the live values the app currently receives from your vehicle (for example RPM, temperatures,
pressures, speed), - your GPS position, speed and heading – only if „Send GPS position and track” is switched on,
- lap timer information (track name, lap times, start/finish line position) when the lap timer is used,
- the optional name you enter for the stream,
- a random link code and a random key generated by the app.
Purpose: to show this information on a web page to the people you give the link or code to.
Anyone who has the link can view the stream while it is available, so share it only with people you
trust. You can create a new link at any time in the app; the old link then stops receiving data.
Retention: stream data is deleted automatically 48 hours after the last update. We do not use it for
any other purpose and we do not combine it with other data.
The stream is not linked to your name, your store account or your device identifiers.
Our web server also records standard technical access logs (IP address, time, requested address,
browser type) for security and troubleshooting; these logs are kept by our hosting provider for
30 days.
Streaming runs only while the app is open and you have started it. You can stop it at any time.
4. Purchases and subscriptions
Purchases and subscriptions are processed by Apple (App Store) or Google (Google Play). We do not
receive or store your payment details. The app receives only the information whether a product has
been purchased or a subscription is active. Please see Apple’s and Google’s privacy policies for how
they process payment data. You can manage or cancel subscriptions in your App Store / Google Play
account settings.
5. Third-party services
- Hosting of the Live stream server: teratarhely.hu, acting as our
data processor. - rusEFI protocol only: to decode the data of a rusEFI ECU, the app may download the matching
definition file from rusefi.com; this request contains the ECU’s firmware signature and your IP
address (standard internet request), no personal data. - Apple / Google: app distribution and in-app purchases.
The app contains no third-party advertising, analytics or crash reporting SDKs.
6. Legal basis (GDPR)
For Live stream we process data to provide the service you have requested (performance of a contract,
Art. 6(1)(b) GDPR). Server access logs are processed based on our legitimate interest in operating a
secure service (Art. 6(1)(f) GDPR).
7. Your rights
You may request access to, correction or deletion of your personal data, restriction of or objection
to its processing, and data portability, by writing to info@linszter.net. Because the app has no
accounts, please include your stream link code so we can find the data. Stream data is deleted
automatically within 48 hours in any case.
8. Children
The app is a tool for vehicle diagnostics and motorsport and is not directed at children under 16.
We do not knowingly process data of children.
9. Safety notice
Do not operate the app while driving on public roads. Use the timing and streaming functions only on
closed roads or race tracks and in accordance with the law.
10. Changes
We may update this policy when the app changes. The current version is always available at
https://linszter.net/tunerview-pro-privacy-policy/ with its effective date.
