EV Battery Health Lite • Developer: Catalyst Fix Pro
Data Collection & Advertisements
Developer-operated servers: Catalyst Fix Pro does not collect or host your vehicle diagnostic history on developer-operated servers as part of normal app operation.
Vehicle Diagnostic Data
EV Battery Health Lite communicates with supported vehicles through compatible OBD2 adapters and may read manufacturer-specific battery-management data such as SOH, capacity-related values, odometer data, cell/module voltage information, temperatures, state of charge, pack voltage/current, protocol responses and adapter information where the selected vehicle/profile supports them.
Technical diagnostic sessions may be stored locally so the user can review connection problems, profile behavior and raw ECU/adapter responses. Depending on the diagnostic function, a technical session may also contain non-unique environment information such as the phone manufacturer/model, Android/API version, EV Battery Health Lite version/build, adapter name/transport/firmware or protocol information, timestamps, response timing, errors and troubleshooting events.
Where a Bluetooth device address is included in technical diagnostic output, EV Battery Health Lite is designed to mask it rather than export the full address by default.
Vehicle Profiles, Profile Revisions & Community Sharing
The application uses vehicle-specific diagnostic profiles. A profile can contain model information, battery-capacity basis, ECU/CAN addressing, read-only diagnostic requests, expected response prefixes, formulas and capability flags.
- Built-in profiles: the current app includes the same 84 built-in vehicle/battery profiles as EV Battery Health. Different battery capacities or diagnostic variants may be represented by separate profiles. Built-in profiles follow a conservative read-only, SOH-first strategy and are not automatically equivalent to a fully verified profile.
- USER/custom profiles: profiles created, edited or imported by the user are stored locally on the device and remain user-managed profiles.
- Profile revisions: supported USER profile workflows may preserve revision history (for example USER v1, v2, v3) rather than silently replacing the previous configuration. A profile version number is a configuration revision and is not a trust or verification level.
- Community exchange: users may intentionally export or share profile data with other people using Android sharing or other external communication tools.
If a user explicitly shares an exported profile, diagnostic TXT/JSON file, report, screenshot or other attachment through email, cloud storage, messaging or another app, that external service processes the shared content under its own privacy policy. Users should review manually attached screenshots or files for personal information before sharing them.
New Vehicle – Profile Help & Optional AI-Assisted Analysis
If a suitable built-in profile does not exist, New Vehicle – Profile Help can collect a read-only diagnostic evidence package for profile development. The exported Help Request or diagnostic package may include vehicle/profile information, adapter/protocol information, diagnostic responses, timing, errors and other technical context needed to analyse a candidate profile.
If the user chooses to upload exported diagnostic information to an AI service, cloud storage provider, email service, messaging app or another third party, that third party processes the shared content under its own privacy policy and terms. Users should review exported files before sharing them and remove personal information they do not wish to disclose.
The intended convergence workflow is read-only: an initial USER profile may be tested on the real vehicle, the resulting evidence may be analysed, and a revised USER profile may then be imported for another test. The app is not intended to bypass SecurityAccess, gateway protection, encryption, manufacturer-only authorization or other vehicle security controls.
Local Storage
The application may store locally:
- profile selections, USER/custom profile data and supported profile-revision information;
- diagnostic session history and timestamps;
- raw adapter/ECU responses and troubleshooting events;
- technical environment metadata needed to understand a diagnostic session;
- application settings;
- user-created TXT/JSON exports or files explicitly saved by the user.
App-private data can normally be removed by clearing app data or uninstalling the application. Files intentionally exported to user-selected storage may remain until the user deletes them.
Internet Connectivity, Consent & Advertisements
An advertisement is not shown merely because the application is opened. The Lite advertising gate is used when a diagnostic function is started.
Google User Messaging Platform (UMP) is used where required to obtain or manage privacy choices. Consent and Do not consent are both supported choices. Consent is not mandatory for using the application.
After the user chooses Do not consent, advertisements may remain unavailable for a longer period. If no advertisement is available at that time, the Lite diagnostic session cannot start. The application may display a message such as “Advertisement is currently unavailable. Try again.” This is a handled no-ad-available state and is not, by itself, a vehicle-diagnostic failure.
The user's privacy choice can be changed later through Privacy Options. Internet access is required for the Google privacy-options interface to load and operate normally.
According to Google's documentation for the Google Mobile Ads SDK, the SDK may automatically collect and share data such as the device IP address, user interactions with the app or advertisements, diagnostic/performance information, and device or account-related identifiers for advertising, analytics, and fraud-prevention purposes. Advertising-ID availability and use depend on Android settings, privacy choices, region and SDK configuration.
An IP address may be used by Google to estimate a general/approximate location. This is separate from Android location permission: EV Battery Health Lite does not request Android precise or approximate location permissions for battery diagnostics.
Catalyst Fix Pro does not intentionally send vehicle SOH, raw OBD responses, custom profiles, Profile Help packages or diagnostic-session content to Google AdMob or UMP.
Device Identifiers & Personal Information
The EV Battery Health Lite diagnostic layer is not designed to collect Android ID, IMEI, Google account identity or exact geographical location, and it does not require a Catalyst Fix Pro user account. Google advertising services may independently process advertising/device/account identifiers as described above and under Google's own policies. Vehicle or device information voluntarily included by the user in an exported file, screenshot or message is shared only when the user chooses to send that content through an external service.
Third-Party Services
The Lite edition may use:
- Google Play Services / Google Play: distribution and platform services.
- Google AdMob: advertising, ad measurement, analytics and fraud prevention associated with advertising.
- Google User Messaging Platform (UMP): consent and privacy-choice handling where required.
These services operate under Google's own privacy policies and terms.
Security, Accuracy & Technical Limitations
- Not all vehicles expose SOH or equivalent battery-health information through OBD2.
- Available parameters differ between vehicles and profiles.
- Manufacturer protocols can vary by model year, battery version, ECU software and market.
- Low-quality or clone OBD adapters may reject commands, truncate responses or behave differently from reference adapters.
- Custom/community profiles may be experimental, incorrect or incompatible with a particular vehicle.
- BMS-reported or profile-calculated SOH may differ from dealer, laboratory or professional battery tests.
Disclaimer of Liability & User Agreement
EV Battery Health Lite is an informational diagnostic tool. It is not a substitute for professional high-voltage battery inspection, repair, safety procedures or manufacturer diagnostic equipment.
- No warranty of diagnostic accuracy: results are provided on an "as is" basis and may vary with vehicle, BMS, adapter, profile and operating conditions.
- User responsibility: the user is responsible for selecting the correct vehicle/profile and deciding how to interpret or use the information.
- Read-only intent: the battery-health workflow is intended to read diagnostic information, not flash, code, repair or reprogram vehicle ECUs.
- Custom profiles: the developer cannot guarantee the accuracy or safety of third-party/community-created profiles.
- Professional assessment: important purchase, warranty, repair or safety decisions should be confirmed by a qualified professional using appropriate equipment.
Children's Privacy
This automotive diagnostic application is intended for adult users and is not directed to children.
Changes to This Policy
This Privacy Policy may be updated as the application, supported transports, profile system, advertising configuration or Google Play requirements change.
