Privacy Policy

Updated 9 November 2026

BimmerLog is an independent BMW diagnostics app published on the App Store by Irina Korneeva. For privacy questions and deletion requests, contact bimmerlogsupport@gmail.com.

Vehicle data on your device

The app connects to your vehicle through Bluetooth, Wi-Fi or ENET. Car profiles, diagnostic readings, fault codes and recordings are stored on your device. Using local diagnostics does not automatically upload your recordings or VIN to our AI service. You choose when to export or share a report or recording.

Optional account

You can continue as a guest or sign in with Apple or Google. Firebase Authentication processes the identity information supplied by your chosen provider, such as an account identifier and, where provided, your name and email address. BimmerLog uses the Firebase account identifier to identify your purchase profile in Adapty. Guest users have an anonymous Adapty purchase profile. An account does not upload or synchronise your vehicle recordings.

You can sign out or delete your account in the app's account settings. Account deletion removes the Firebase account after reauthentication. It does not cancel an App Store subscription, erase local vehicle files or delete billing records retained by Apple and Adapty. Manage subscriptions through your App Store account and contact support for other deletion requests.

Purchases

Apple processes payments; BimmerLog does not receive card details. Adapty processes purchase and subscription information, product and transaction identifiers, entitlement status, installation information and your purchase profile identifier so the app can provide and restore paid access. Subscription events are also forwarded to our analytics services to measure product performance. Purchase records may remain after account deletion where needed to restore purchases, resolve billing issues or meet retention obligations.

Usage and advertising measurement

We use Google Firebase Analytics and AppMetrica to measure app sessions, screens and actions, including onboarding, adapter-type selection, sign-in outcomes and paywall outcomes. These services also process standard device, app and installation metadata, including approximate country or region inferred from network information. BimmerLog does not request GPS location for analytics. The app does not put your name, email, VIN, vehicle readings, recordings, search text, browser URLs or the contents of AI conversations into these analytics events.

Adapty receives a limited set of setup attributes: sign-in method, onboarding version and progress, completion status, adapter type and the country selected for adapter shopping. This country is a user choice or device-region default, not GPS location. Firebase and AppMetrica installation identifiers are supplied to Adapty to associate subscription events with analytics.

Apple's AdServices attribution token is processed through Adapty to measure whether an installation came from Apple Ads. This can associate a purchase profile with an advertising campaign. IDFA collection and ad personalisation signals are disabled in the app's SDK configuration. Our analytics integrations do not send a second set of client-side revenue events.

Optional AI analysis

When you request an AI analysis or ask a question, the app sends the selected diagnostic context to bimmerlog.pro: vehicle model, engine and mileage, relevant fault codes and readings, calculated facts and excerpts from the chosen recording, your question and earlier messages in that conversation. The AI request excludes the VIN. Avoid including names, contact details or other personal information in questions.

Our server passes the request to OpenRouter and the selected AI model provider to produce an answer. The server uses a random installation token and usage counters to apply limits. Network services also receive your IP address; registration records and operational logs may contain it. Server usage records include request time, installation reference, token usage and cost, rather than the contents of the AI request.

Optional developer report

If you choose to send a developer report from Settings, it can contain the VIN, vehicle identification, control-unit information and diagnostic responses needed to investigate compatibility or a problem. This is separate from AI analysis and is sent only after you request the report. Do not send it if you do not want that diagnostic information shared with support.

Adapter shopping and external links

If you open adapter shopping, an in-app browser loads a Google search based on an adapter query and the selected country. Google and any shop you open process browser requests under their own privacy policies. BimmerLog does not log your search text or visited URLs as app analytics events. External privacy, support and subscription-management links open the relevant service.

Service providers

The services used for these purposes include Apple, Google/Firebase, Adapty, AppMetrica, OpenRouter and the AI model provider selected for a request. They may process data outside your country. Their privacy information is available below:

Retention and your choices

Local files remain on your device until you delete them or remove the app; copies you export or include in a device backup may remain separately. Provider-managed account, analytics and purchase records are subject to the relevant service's retention and deletion settings. We use server records for service operation, limits, troubleshooting and support; contact us to request access, correction or deletion of information associated with your account or installation.

Declining AI analysis prevents AI requests, but does not by itself disable account, purchase or usage-analytics processing. You can use the app without signing in and can choose not to send developer reports. For privacy requests, explain the app account or installation concerned without sending passwords, payment-card details or unnecessary vehicle information.

Children and changes

BimmerLog is intended for vehicle owners and is not directed at children. Changes to this policy will be published here with an updated date.
