LLCAR Privacy Policy

Version dated 24 October 2026.

1. Who processes the data

The data controller (operator) is LLKAR, OOO (in Russian: ООО «ЛЛКАР»).
OGRN (primary state registration number) 1267700152785, INN (taxpayer identification number) 9734025407, KPP 773401001.
Address: d. 34 k. 3 kv. 784, naberezhnaya Shelepikhinskaya, Moscow 123290, Russia.
Email: llcar@llcar.ru. Support phone: +7 930 321-00-08.

This Policy applies to the LLCAR app for Android and iPhone, to the llcar.ru website and to the LLCAR services that the app uses.

The app is intended for adult car owners and drivers. It reads vehicle data through an ELM327 adapter plugged into the car's OBD-II port.

2. What data we receive and why

The data depends on which features you have turned on. All data that the app may send from your phone is listed below.

2.1. Account

Email address. You provide it to sign in to your account with a code sent by email, or to get access to your organisation's fleet. We use it to sign you in and to contact you.

Phone number. You may enter it in the settings if you wish. We use it to contact you and to link a vehicle.

Client identifier. The app generates it automatically. It links your records on the server to each other. It does not tell us your name.

2.2. Vehicle data

  • VIN and licence plate number, if you have entered them.
  • Make, model and year of the vehicle.
  • Readings provided by the vehicle: engine speed, road speed, temperature, voltage and other parameters.
  • Trouble codes and the time they appeared.
  • Logbook entries: maintenance, repairs, refuelling, events and notes.

We need this data to show you the condition of your vehicle, keep its history and provide explanations. If you have a subscription that includes storing history on the server, the readings are sent to and stored on the LLCAR server.

2.3. Location, including in the background

The “Place tags” feature is off by default. You turn it on yourself in the app.

Before the feature is turned on, the app shows an explanation. After you agree, Android asks for permission to access your location, including in the background.

When the feature is on, the app uses your location even when it is minimised, closed or the phone screen is locked. This is needed so that readings recorded during a trip receive a place tag.

The phone converts the coordinates into a place tag. A place tag identifies an area of approximately 40 by 20 metres. Only the place tag is sent to the LLCAR server together with the readings. Exact coordinates are not sent to the LLCAR server.

Place tags are used to compare how the vehicle behaves at the same places, for example on the same hill or the same road.

To show the weather during a trip, the app sends coordinates to weather services (Section 4).

Android also requires location access to search for the Bluetooth adapter. For this purpose the coordinates are not sent anywhere.

You can turn off “Place tags” in the app settings or deny location access in your phone settings.

2.4. Microphone and sound

Sound analysis is turned on and off in the app settings.

When the feature is on, the app listens to engine and suspension sound during a trip, including when the screen is locked. While recording is in progress, an app notification is visible on the phone.

Sound is analysed on the phone. Only numerical sound features are sent to the LLCAR server, not the recording itself. Sound recordings are not stored. Conversations are not recorded.

You can turn off sound analysis in the app settings or deny microphone access in your phone settings.

2.5. Voice questions

A voice question to the AI assistant is converted into text by the speech recognition service built into Android. On many phones this is a Google service. It may send the recording of the question to its servers and processes it under its own terms. LLCAR does not receive or store voice recordings.

2.6. AI assistant

The AI assistant's answers are generated by a model that runs on the phone. The model file is downloaded from the LLCAR server after installation.

Every answer has a “Report a problem” button. If you tap it, the question and the answer are sent to LLCAR support.

2.7. Knowledge base search

When you search for an article, the text of your search query may be sent to the websites where the articles are hosted. Your identifier, VIN and other account data are not sent with the query.

2.8. Camera

The camera is used to read QR codes: to link the app to your account on the website or to join a fleet. The image is processed on the phone and is not sent anywhere.

2.9. Motion sensors

The app reads the phone's motion sensors to detect vehicle vibrations during a trip. Only numerical vibration features are sent to the server.

2.10. Support requests

When you send a support request from the app, LLCAR receives the description of the problem, the make, model and year of the vehicle, the reason for the request, the client identifier and the app's technical log. The log may contain the VIN, phone number, error information, phone model and search queries.

Requests are handled by LLCAR support staff.

2.11. Community articles and rules

You may submit an article or a rule to the shared knowledge base. A moderator reviews each submission. After review, other users can see it.

If you believe an article is incorrect or inappropriate, tap “Report” on the article.

2.12. Organisation fleets

If the organisation you work for has connected to LLCAR, you are given access to its fleet by your email address. The organisation's administrator can see your email address or name, your role and access, as well as data on the fleet's vehicles: readings, events, notifications and the time of the latest data.

2.13. Payment

Subscriptions are purchased on the llcar.ru website. Payments are accepted by the YooKassa payment service (ЮKassa). Bank card details are entered on the YooKassa page. Neither the app nor LLCAR receives them. From YooKassa we receive the payment number, amount, date and status.

2.14. What we do not do

  • There is no advertising in the app.
  • The app contains no third-party analytics services.
  • We do not sell data.
  • We do not use data for advertising.

3. Legal grounds for processing

We process data to perform our contract with you: to make the app work, maintain your account, store history and respond to requests.

For features that you turn on yourself (place tags, sound analysis), we rely on your consent. You may withdraw it at any time by turning the feature off.

We keep payment records because the law requires it.

4. Who we share data with

  • The weather services Open-Meteo (open-meteo.com), MET Norway (api.met.no) and wttr.in. If the app is allowed to access your location, it sends them coordinates to show the weather during a trip. Only the network address of the request is sent together with the coordinates. Your identifier and vehicle data are not shared.
  • Websites hosting articles. They receive the text of the search query (Section 2.7).
  • The Android speech recognition service (Section 2.5).
  • The YooKassa payment service (Section 2.13).
  • Contractors who maintain the LLCAR servers on our behalf. They are required to protect data to at least the standard described in this Policy.
  • AI services used to prepare support replies: GLM (Z.ai), MiMo, OpenAI, and, for looking up reference information, Bing and Z.ai Web Reader. To prepare a draft reply, a support employee composes a separate technical question from the request: the description of the fault and the make, model and year of the vehicle. The VIN, client identifier, name, phone number and email address are not included in this question. The reply is checked and sent to you by an employee.
  • The fleet administrator of your organisation (Section 2.12).
  • Government authorities, only where required by law.

5. How we protect data

The app transmits data to the LLCAR server over a secure HTTPS connection.

Only employees who need access for their work can access the data on the server.

6. How long we keep data

  • The account and links are kept for as long as the account exists.
  • Reading history on the server is kept for as long as a subscription with history storage is active or for as long as the account exists.
  • Support requests are kept for as long as they are needed to resolve the issue.
  • Payment records are kept for the period required by law.
  • Data stored only on the phone is deleted together with the app.

7. How to delete your account and data

In the app: Settings → Client Identity → “Delete account and data”.

Without the app: on the page llcar.ru/account/delete or by email to llcar@llcar.ru.

The account and links are deleted immediately after confirmation. Reading history on the server is deleted within 30 days. Backup copies are deleted within the following 7 days.

Automatic subscription renewal is turned off when the account is deleted. You can manage your subscription in your personal account.

Payment records are retained for the period required by law.

Uninstalling the app from your phone does not by itself delete your account or the data on the server.

8. Your rights

You may find out what data we hold about you, obtain a copy, correct it, ask us to delete it or restrict its processing, and withdraw your consent.

To do so, write to llcar@llcar.ru. We will reply within the time limit established by law.

You may lodge a complaint with Roskomnadzor (the Russian data protection authority) or with a court.

9. Children

The app is intended for adults. We do not knowingly collect children's data. If you become aware that a child has provided us with data, write to llcar@llcar.ru and we will delete it.

10. Website and app downloads

The server counts successful responses to requests for the app file per day. This counter does not store IP addresses, cookies or visitor identifiers. Repeated requests are counted separately. These figures do not confirm that a download was completed or that the app was installed. Yandex Metrica is not used on the website.

11. Changes to this Policy

A new version is published at llcar.ru/privacy. We will notify you of material changes in the app before they take effect.
