Terms of Use

Service description

PhotoMeterPro provides exposure metering using the iPhone camera as a luminance sensor. Displayed ISO, aperture, and shutter values are computed from real sensor readings and your selected gear parameters. AI advisors provide interpretive recommendations — they do not replace professional judgment or certified light meters.

Accuracy disclaimer

PhotoMeterPro does not guarantee industrial-grade light measurement accuracy. Results depend on the iPhone model, sensor characteristics, and calibration. Use MeterCalibrationStore for manual offset adjustment against a known reference.

Pro subscription

Pro features require an active StoreKit 2 subscription. Subscription management and pricing are handled through your Apple ID and the App Store. Refunds follow Apple's App Store policies.

AI features

AI advisor outputs are generated by OpenAI models and may contain errors. They are intended as guidance, not definitive exposure settings. Rate limits apply (30 AI requests per 60 seconds per IP on the backend).

Acceptable use

You may not abuse the AI API, attempt to bypass rate limits, or use the app for purposes that violate applicable law. The backend API has no authentication — abuse may result in IP blocking at the infrastructure level.

Limitation of liability

Photo Meter Pro and its developers are not liable for exposure errors, data loss, or damages arising from use of the app or AI recommendations. Cloud sync and backend storage are provided as-is; backend sync data is ephemeral.
