ToneLatch Privacy Policy

1. Local-only image processing

ToneLatch is designed to process supported image files locally on your computer. The normal desktop workflow does not upload photo content for RAW decoding, gain-map generation, Ultra HDR export, or Native HDR export.

2. Data stored locally

The app may store local settings and workflow state on your device, including:

• last used folder and output settings
• HDR strength preferences
• whether certain warnings should be shown again

3. Files you choose to process

When you choose a folder or image pair, the app reads those files locally to match RAW and JPEG pairs, generate an HDR gain map, and write the output JPEG to the selected destination. Original source files are not intentionally overwritten by the normal workflow.

4. Network activity

The current desktop build does not require a cloud account to process images. It may contact Apple, Logic & Light services, or the ToneLatch website for App Store distribution, update-related checks, support links, or website analytics. These network requests do not upload your photo content for HDR processing.

5. Website and support interactions

If you contact Logic & Light by email or use the website, that interaction may be handled by third-party services such as hosting, analytics, or email providers. Those services may have their own privacy policies.

6. Analytics

The ToneLatch website currently uses Google Analytics to understand page visits, referral sources, and basic site usage. This analytics does not include your photo content. The current desktop app does not upload image-processing telemetry for the images you process locally.

7. Mac App Store distribution

When you download or purchase ToneLatch through the Mac App Store, Apple handles the transaction and may collect information as described in Apple's Privacy Policy. Logic & Light does not receive your payment card details from App Store transactions.

8. Your responsibility

You are responsible for the files you choose to process, store, and export, including any personal data contained inside image metadata.
