Balance the pot before you touch the heat.
Coctio Jam is a professional biochemical calculator and interactive cook simulator that balances pectin, sugar, and acidity — so every batch sets clean, tastes right, and holds its shelf-life.
Built for the chemistry of a perfect set
Every tool traces back to the same three variables that decide whether a batch sets, weeps, or over-firms: pectin, sugar, and acid.
Pectin Balance Engine
Calculate precise pectin dosage for HM, LM, and naturally high-pectin fruit, matched to batch weight and desired firmness.
Sugar Ratio Calculator
Instantly compute the sugar-to-fruit ratio needed to hit target soluble solids for a stable, shelf-stable set.
Acidity & pH Guidance
Get the target pH window for your pectin type so gels set cleanly, without weeping, crystallizing, or breaking down.
Interactive Cook Simulator
Model a full cook — temperature ramp, evaporation, and set point — before a single piece of fruit hits the pot.
Shelf-Life Optimizer
Translate your ratios into an estimated shelf-stability outlook so every jar leaving the kitchen is safe and consistent.
Batch Scaling
Scale any formula from a single test jar to a full production run without losing precision on any variable.
The Ratio Calculator
Enter your batch weight and pectin type — we'll suggest a sugar ratio, pectin dosage, and target pH window for a clean set.
Suggested formula
This is a simplified guide built on classic preserve-making ratios — always confirm final set with a refractometer or wrinkle test in your own kitchen.
Why we built Coctio Jam
We're a small team of food technologists, pastry chefs, and software engineers who got tired of guessing at set points. Coctio Jam started as an internal tool for balancing pectin, sugar, and acid on the line — we built it because the spreadsheets and sticky notes we were using simply couldn't keep up with a real production kitchen.
Our mission is to bring laboratory-grade precision to a craft that has historically relied on instinct and trial and error. We believe chefs and pastry artisans deserve tools that respect both the science of gelation and the art of flavor — without forcing them to choose between the two.
Coctio Jam gives you a biochemical calculator that balances pectin type, sugar ratio, and acidity in seconds, plus an interactive cook simulator that lets you model temperature, evaporation, and set point before you commit fruit to the pot. Every recommendation is grounded in the same chemistry that governs how a gel actually forms and holds.
It matters because a single miscalculated ratio can mean a weeping jar, a crystallized batch, or a shortened shelf-life — costly in a professional kitchen. Get the ratio right, and the rest is craft.
Coctio Jam — precision in, perfection preserved.
Your kitchen data stays in your kitchen
Coctio Jam was built as an offline, professional-grade instrument for kitchens and labs — not a data platform. Every calculation, every simulated cook, and every saved formula lives entirely on the device it was created on. This policy explains, in plain terms, what that means for you.
1.Information We Collect
We collect nothing. Coctio Jam does not request accounts, does not ask for your name or email to function, and does not gather usage statistics, device identifiers, or location data. The pectin, sugar, and acidity figures you enter are yours alone and never leave your device.
2.How We Use Information
Because no information is collected, none is used, analyzed, aggregated, or sold. There are no algorithms behind the scenes studying your recipes, batch sizes, or cook simulations — the app has nothing to send us, and we have nothing to look at.
3.Data Storage
Any formulas, saved batches, or calculator inputs are stored locally on your device only, using standard on-device storage. There is no cloud account, no remote database, and no backup server operated by us. If you delete the app, that local data is gone with it.
4.Third-Party Services
Coctio Jam contains no analytics software development kits, no advertising networks, and no third-party trackers of any kind. The app does not communicate with external servers to function, so there is no third party for your data to pass through.
5.Data Security
Because your ratios and cook simulations never transmit off the device, there is no network transmission to intercept and no remote server to breach. Security here means the calculator runs entirely within the safe, closed environment of your own device.
6.Children's Privacy
Coctio Jam is a professional tool intended for chefs, pastry artisans, and food technologists, and is not directed at children. In any case, since the app collects no data from any user of any age, it does not knowingly or unknowingly gather information from children, in line with COPPA principles.
7.Your Control
There are no accounts to manage and no server-side profiles to request the deletion of. You retain full control at all times: deleting the app from your device permanently removes every formula, batch note, and simulation stored within it.
8.Changes to This Policy
Should our practices ever change — for example, if a future version introduces an optional cloud-sync feature — we will update this policy and revise the Effective Date above before that change takes effect, so you always know what governs your data.
9.Contact
Questions about this policy can be sent to privacy@coctiojamapp.com. We're glad to explain, in as much technical detail as you'd like, exactly how little data ever leaves your kitchen.
