Measure with purpose
Capture cabin and zone dimensions with yacht-fit calculators. Work in metric or imperial, organize measurements by zone, and keep reference context at hand while you move through the vessel.

What it does
Everything a refit loft needs, in one calm studio.
JoinerLoft turns scattered cabin dimensions, material notes, and yard status into a structured record you can trust — from first measure to final handoff.
Specify with confidence
Browse a curated marine material library — teak, veneers, fabrics, hardware, lighting, surfaces, and finishes. Filter by humidity, salt spray, and UV exposure, then compare options side by side.
Craft like a pro
Technique guides explain why a method is chosen for marine interiors, so your team can align on approach during survey, loft, and install.
Track every refit
Manage multiple vessel projects, phases, and on-site fit-out sessions. Start a timed session, attach zone reference photos, and export a clear overview for the yard or design team.
Studio command center
See active projects and climate context in one place. Checklists, snags, and field calculators keep survey and install work aligned across the team.
Built for the worksite
Live Activity on the Lock Screen for on-site sessions. Home Screen support, plus layouts tuned for iPhone and iPad so the loft travels with you.
About
Built for designers, joiners, and project leads.
JoinerLoft is a floating studio for yacht and superyacht interior refit work. It brings cabin measures, marine material specification, joinery technique guidance, and project tracking into one calm place — designed for the loft, the survey, and the install bay.
Whether you are specifying teak for an owner suite or timing a fit-out session on board, JoinerLoft helps you measure, specify, craft, and hand off with clarity. Your projects, measurements, photos, and notes stay on your device.
Privacy policy
Your loft records stay on your device.
JoinerLoft is built so your projects, measurements, and notes remain under your control. This policy describes what the app stores locally and when it may use optional network services.
Effective date: July 17, 2026
Information We Collect
JoinerLoft does not require an account, sign-up, or login. We do not ask for your name, email, or phone number inside the app, and we do not run advertising or analytics SDKs that profile your activity.
Content you create — projects, measurements, material selections, technique bookmarks, session timing, checklists, snags, and optional zone photos — is stored locally on your device.
How We Use Information
Local data is used only to power the features you see in the app: organizing refit projects, measuring cabins, specifying materials, following techniques, and exporting a summary when you choose to share one.
We do not sell personal information. There is no JoinerLoft cloud account that stores your loft records remotely.
Data Storage
Project data is saved in the app’s private storage on your device (including UserDefaults and, for zone photos, files in the app’s Documents folder). A shared App Group may hold a short Live Activity / widget snapshot so Lock Screen and Home Screen surfaces can show session status.
If you delete the app, associated local data is removed with it, subject to your device’s normal backup behavior.
Optional Permissions & Network
Location (When In Use): If you enable automatic climate context, the app may use your approximate location to fetch relative humidity from the Open-Meteo weather API. You can instead choose a manual climate preset and work without location.
Camera & Photos: You may attach zone reference photos from the camera or your library. Those images stay on your device unless you export or share them yourself.
Catalog imagery: Some decorative or catalog images may be loaded over the network and cached on device. Core materials and technique content is bundled with the app and works offline.
Live Activities: On-site session progress can appear on the Lock Screen via ActivityKit. This does not use remote push notifications.
Third-Party Services
When optional network features are used, JoinerLoft may contact:
- Open-Meteo — relative humidity for climate guidance
- Image CDNs (for example Unsplash or Picsum) — decorative / catalog imagery
Those services receive only what is needed for the request (such as coordinates for humidity or an image URL). JoinerLoft does not include third-party advertising or analytics SDKs.
Data Security
Your loft records are protected by your device’s own safeguards. Optional network requests use standard HTTPS. Because most of your content never leaves the device, exposure from remote storage is minimized.
Children’s Privacy
JoinerLoft is not directed at children under 13. The app does not knowingly collect personal information from children. If you believe a child has provided personal information through support channels, contact us and we will address it.
Your Control
You can edit or delete projects, measurements, and notes at any time inside the app. You may export a local JSON backup via Settings when you want your own copy. You can revoke location, camera, or photo access in iOS Settings.
Changes to This Policy
We may update this policy to reflect product or legal changes. When we do, we will revise the effective date above. Continued use of the app after an update means you accept the revised policy.
