CocoCalc is an independent iOS app that calculates CANNA Coco feed recipes. This policy explains exactly what the app does and does not do with your information.
In one sentence: CocoCalc runs entirely on your device — it has no servers, no accounts, no analytics, no ads, and makes no network connections at all; the only data it keeps is your calculator preferences, stored locally on your phone.
Who we are
CocoCalc is built and maintained by an individual developer ("we", "us"). The app is not affiliated with, endorsed by, or sponsored by CANNA. "CANNA" and all product names are trademarks of their respective owners, used only to identify the products the app calculates doses for.
What the app stores, and why
| Data | Purpose | Where it goes |
|---|---|---|
| Calculator inputs (batch volume, source-water EC) | Remember your last mix so you don't re-enter it | Stored locally on your device only |
| App preferences (theme, EC unit, keep-screen-awake) | Remember how you like the app to look and behave | Stored locally on your device only |
| Products you own (which bottles to include) | Tailor the recipe to the products you have | Stored locally on your device only |
| Disclaimer-acknowledged flag | Avoid re-showing the first-run notice once you've seen it | Stored locally on your device only |
These are saved in the app's local settings (iOS UserDefaults) on your
device. We collect this solely to provide the app's functionality. We
do not use any of it for tracking, advertising, profiling, or analytics.
What we do NOT do
- We do not operate any backend server, and the app makes no network requests.
- We do not require an account, name, email, or any sign-in.
- We do not collect analytics or telemetry about you or your usage.
- We do not include advertising or third-party tracking SDKs.
- We do not sell, rent, or share your information — because none of it ever leaves your device.
Where your data is sent
Nowhere. CocoCalc works fully offline and does not transmit any data off your device.
Deleting your data
All of the app's data lives on your device. Deleting the app removes everything it has stored — there is nothing held anywhere else to delete.
Children
CocoCalc is a horticultural calculator and is not directed at children under 13.
Changes to this policy
We may update this policy as the app evolves. Material changes will be reflected by the "Last updated" date above.
