Feature · Multi-device cloud sync
You calibrate at the workshop. You find everything at home.
Your correction curves, your presets and your chart scans sync automatically across all devices connected to the same account — in real time, via Firestore, with strict per-account isolation. No manual handling, no intermediate export.
Typical scenario
Workshop in the morning, Mac in the evening.
You are in your workshop with your iPad. You photograph your chart, you analyse the 21 steps, you generate your correction curve .acv and you save it to your library.
In the evening, you get home. You open Calibration Flow on your Mac — your curve is already there. You export it directly to Photoshop or Lightroom to prepare your next exposure session.
Zero cable. Zero email. Zero shared folder to maintain.
Under the hood
- 01Real-time Firestore — as soon as one device writes data, all the others receive it with no delay.
- 02Strict per-account isolation — each uid is a distinct partition. Your data never crosses another user’s.
- 03Local IndexedDB cache — if you have no connection, the app keeps working. Sync resumes as soon as you are back online.
- 04No manual management — every save to your library triggers the sync automatically. No extra action required.
Synced content
Everything that matters for your calibration.
Correction curves
Your tonal corrections .acv
Every curve generated or edited in your library — tied to a process, a paper, a print — is available on all your devices as soon as it is saved.
Calibration presets
Your paper × process profiles
Paper, process, sensitiser, UV source — every preset you build is shared instantly across all your connected devices.
Chart scans
Your reference images
Analysed chart photos are synced within your cloud quota. You can review them, compare sessions and track your process over time.
Access & quotas
Sync is included from the free account.
Sync is not reserved for Pro: it is active for all accounts. It is the cloud storage quota that differentiates the plans — not the feature itself.
