The Pro subscription is the paid tier of Calibration Flow. A single price of €9.90/month valid on the web and on iOS, managed from your Picturale account. It funds active development of the tool and gives you access to the extended quotas as well as the advanced functions that aren't available in free mode.
If you bought a Luminograph from Vision Picturale, 1 year of Pro is included at no extra cost — see Luminograph code.

#How to activate
From the app (web or iOS), you go to the Account menu → "Activate Pro mode". You're redirected to the subscription page on
picturale.appThe price is single: €9.90 incl. tax/month, automatic monthly billing, renews automatically. No fixed-term commitment.
#How to cancel
Cancellation is possible at any time from your account on
picturale.appEffect: you keep Pro access until the end of the period already paid for, then you drop to free mode. Your data stays intact, only the quotas apply. If you had more than 3 curves when the subscription ends, you keep everything read-only until you delete enough to drop back under the threshold, or until you reactivate Pro.
#Why it matters
The €9.90/month price positions Calibration Flow as an accessible pro photo tool. Photoshop alone costs €23.99/month on the single plan, Lightroom €11.99/month, PiezoDN (the closest direct competitor in alt-process) is a €100 one-shot license. Calibration Flow at €9.90/month stays below the standalone Adobe tools, while offering a specialized alt-process tool you won't find anywhere else.
The model is deliberately simple: a single subscription, web and iOS unified, that unlocks every function and the extended quotas. No intermediate tier to choose, no add-on modules to buy separately.
#When you don't need it
You use Calibration Flow occasionally. At one calibration every two months or less, free mode is plenty (3 curves, 300 MB). The Pro subscription becomes useful from five to eight calibrations a month, or if you practice several processes in four-color.
You've just bought a Luminograph. The purchase includes 1 year of Pro for free — no need to subscribe on top. See Luminograph code.
You want to try before committing. Free mode doesn't expire. You can practice for months on the free tier before deciding whether Pro is worth it for your workflow.

#The test
Subscribe from your web account. Check right away that you can:
- Open the full-gamut Color Venn in the Negative module when you pick CMYK mode (the Pro badge should disappear).
- Reach the advanced export options in the library (they should be active).
- See your storage quota go from 300 MB to 5 GB in the library.
- Sign in on iOS with the same account: the Pro status should be active on both platforms with no new subscription.
If you don't need Pro after a week, cancel from
picturale.app
