Yakitsuke 焼付け

Privacy policy

Effective 14 October 2026. Covers the Yakitsuke Mac app and yakitsuke.com.

In short

  • Yakitsuke has no account, no ads and no analytics or tracking.
  • Your photos stay on your Mac and your camera. We never receive them.
  • The app contacts our servers in only two cases: to check for updates, and when you choose to send a bug report.
  • Bug reports are deleted automatically after 90 days.

Who we are

Yakitsuke is made by Cheng-Hsien Han, an independent developer (“we”, “us”). For anything about this policy or your data, write to support@yakitsuke.com.

What stays on your Mac

Yakitsuke works on your Mac. It keeps the following there, and none of it is sent to us unless it goes into a bug report you send (see below):

Files you export are saved where you choose, next to the RAF by default. They keep the metadata your camera writes, which can include location if your camera recorded it, and JPEGs also record the recipe used.

To remove everything Yakitsuke keeps, delete the app and the folders ~/Library/Application Support/Yakitsuke and ~/Library/Logs/Yakitsuke.

Your camera

To develop a photo, the app sends the RAF to your camera over USB, takes back the result, and deletes the temporary file from the camera. It reads the camera’s serial number to recognise it while connected, but does not save it or send it to us. It changes the camera’s custom settings (C1–C7) only when you ask, and backs all of them up first.

If macOS is holding the camera, the Release camera button stops the macOS processes that claimed it (ptpcamerad and PTPCamera). It does this only when you click it.

Update checks

The app checks updates.yakitsuke.com for a new version when it starts, every 4 hours while it runs, and when you click Check for updates. Versions up to 0.3.0-beta.4 use yakitsuke-updates.richohan.workers.dev, which is the same server.

Bug reports

A report is sent only when you open Report a problem (or accept the offer after a crash), review its contents and click Send. Nothing is sent automatically. You can choose Save as file instead and send nothing.

What a report contains

PartDetails
What you writeThe title, description and steps, and your email if you give one.
App and systemApp version, macOS version, processor type, language and region setting, how long the app had been running, and whether its last run ended unexpectedly.
CameraModel, firmware, connection state and battery level. The serial number is replaced with a short code.
DiagnosticsThe last 7 days of app and USB logs, recent queue and conversion history (with file names, recipe names and settings), library counts, the app’s settings, a random ID Yakitsuke creates for this installation (not the update ID above), and crash data from the last 7 days.
ScreenshotOnly if you tick the box, which is off by default. It shows the app window, which can include your thumbnails and file names.

Removed before sending: your Mac user name, the names of your library and export folders (replaced with short codes), and the camera serial number. File names and recipe names are kept. Crash data and screenshots are not changed. Crash data is a snapshot of the app’s memory at the time of a crash and can contain anything the app had open, such as file paths.

Never included: your photos or RAW files.

Where a report goes and how long it is kept

After sending, the app shows a report ID (for example YK-7Q2M4X). Quote it if you want us to look at, correct or delete your report.

AI agents (optional)

This is off until you turn on Let AI agents use Yakitsuke in Settings. Then AI apps on your Mac that you connect, such as Claude Desktop or Claude Code, can use Yakitsuke’s tools through a connection that only programs on your Mac can reach.

This website

yakitsuke.com uses no cookies, analytics or third-party scripts, and its fonts are served from this site. Cloudflare hosts it and processes your IP address to deliver the pages. Our code does not log visits.

Service providers

Both may process data in the United States and other countries where they operate. We don’t sell or share your data with anyone else, and we don’t use it for advertising.

Why we use this data

Update checks keep the app working and secure, which is our legitimate interest and yours. Bug reports are sent because you choose to send them, and we use them only to find and fix problems. You can ask us to delete a report at any time.

Your rights

Depending on where you live, including under Taiwan’s Personal Data Protection Act and the EU and UK GDPR, you can ask to see, get a copy of, correct or delete data we hold about you, or ask us to stop using it. Write to support@yakitsuke.com with your report ID if you have one. You can also complain to your local data protection authority.

Sending a bug report is optional. If you don’t, the app works the same; we just can’t see the problem.

Children

Yakitsuke is not directed at children, and we don’t knowingly collect data from them.

Changes

If this policy changes, we will update this page and the date at the top. If the app starts sending anything new, the policy will say so before that version is released.
