Haku — Privacy Policy
Effective 2026-08-20
Haku is a camera app. Your photos are yours, and Haku is built so that nothing about them — or you — ever reaches us or anyone else.
What Haku collects
Nothing. Haku has no accounts, no analytics, and no advertising. The app never transmits anything about you or your photos.
Haku makes network requests only in the Community page of Recipes, and nowhere else in the app:
- Fetching the public list of community-shared recipes, its vote counts, and the photographs their authors chose to show them on. These are files in a public repository, downloaded the way a browser downloads a page; nothing is sent with them beyond what any download carries.
- Voting, when you tap the thumbs-up on a recipe: the recipe's name is sent and nothing else. No account, no identifier, nothing about you or your phone.
- Submitting, and only when you tap Submit on a recipe you chose to offer: the recipe's settings, the name you asked to be credited, the line you wrote about it, the tags you picked, and the one to three photographs you selected. Those photographs are rendered fresh from your originals for the purpose, which means they carry no location, no camera details and no other metadata - the original never leaves your phone. It all goes to a small relay of ours that files it for review, and is published only if it is approved.
Never visiting that page means Haku makes no requests at all.
What stays on your device
- Photos, videos and edits. Originals, RAW files, recordings, edit recipes and thumbnails are stored in the app's private container on your device, in your iCloud/system Photos library if you choose a storage mode that uses it, or both. Haku never sees them anywhere else.
- Sound. Recording a video captures audio through the microphone, which is written into that video file and nothing else. Haku does not listen at any other time, and declining the microphone permission records silent video rather than no video.
- Location. If you grant location access, the current location is embedded in each photo's EXIF metadata — the same field every camera writes — so Photos can place your shots on a map. It is written into your own files and nowhere else. Decline the permission and everything else works unchanged.
- Settings and film looks. Your preferences, custom setups, recipes and any LUT files you import are stored on your device only.
Sharing
When you share a photo, a video, a recipe or a film look, it goes only where you send it — AirDrop, Messages, or whatever you choose in the share sheet. Haku adds nothing and tells no one.
Offering a recipe to the community is described above: it is sent only when you tap Submit, and only what is listed there. If the relay cannot be reached, Haku falls back to copying the recipe to your clipboard and opening the submission page in your browser, where posting it is between you and GitHub under your own account.
Haku points outward in a few places, and each one simply opens your browser: Fujifilm's public download page for their film-simulation LUTs, a download link an author supplied for a film look their recipe needs, the page where a recipe's votes live, and your mail app if you choose to report a problem. Nothing is sent when you tap any of them.
Third parties
There are none. No SDKs, no trackers, no analytics services.
Changes
If a future version of Haku ever changes any of this, this policy will change with it, and the change will be visible in the App Store listing before you update.
