Effective date: August 28, 2026

Information entered into the tool

Voltage readings and symptom selections are processed in your browser. StartVitals does not require your name, account, VIN, license plate or precise location to produce a result.

Local browser storage

The tool may save the latest result plus up to five recent test records in local storage on your device. This enables an optional before/after comparison when you retest the same vehicle. The information is not automatically transmitted to StartVitals. You can remove it by clearing site data in your browser.

Server logs

Like most websites, the hosting provider may process standard technical logs such as IP address, requested URL, timestamp, browser type and security events. These logs are used for delivery, reliability and abuse prevention and are retained according to the hosting provider’s operational settings.

Advertising and consent

No advertising identifier is configured in the launch package. If Google AdSense or another provider is enabled later, the provider may use cookies or similar technologies for ad delivery, measurement, fraud prevention and—where permitted—personalization. A consent mechanism will be enabled where required before personalized advertising is used.

Analytics

The launch version contains no third-party analytics code. If privacy-respecting analytics is added later, this policy will be updated before collection begins.

External links

Source links lead to third-party sites with their own privacy practices. StartVitals does not control those sites.

Children

StartVitals is intended for adults performing or supervising vehicle maintenance. We do not knowingly collect personal information from children.
