Privacy policy

Effective October 31, 2026

Who we are

Runoff Radar is made by Bonsai Nutrients in British Columbia, Canada. In this policy, “we” means the people who make Runoff Radar, and “you” means the person using it.

What stays on your phone

Everything you enter in Runoff Radar is saved only on your iPhone, in the app’s own storage:

• Your rooms, their tables and pots, and their names and colours.
• Your runoff tests: the dates, the PPM or EC and pH readings, and your feed numbers.
• The notes you write on a test.
• Photos you choose for a room cover or a test. Runoff Radar copies only the photo you pick into the app.
• Your settings, like your units, table look, PDF style and the name you put on reports.

We do not run servers that store this information, and we cannot see it. If you delete Runoff Radar, this information is deleted with it, unless it is part of your own iPhone backup.

When information leaves your phone

• When you share a PDF. The PDF goes only where you send it (Mail, Messages, Files and so on). That app’s own privacy policy applies.
• Purchases. Payments are handled by Apple. We use RevenueCat to check whether your free trial has started and whether you own the Runoff Radar unlock. RevenueCat receives a random app ID (not your name or email) and your App Store purchase details. See RevenueCat’s privacy policy.
• App updates. Runoff Radar checks for app improvements through Expo’s update service, which receives basic technical details like the app version and device type, a random installation ID that stays the same until you reinstall the app, plus your IP address as part of any internet connection. See Expo’s privacy policy.

What we don’t do

• No accounts or sign-in.
• No advertising, and no ad or analytics trackers.
• No tracking across other apps or websites.
• No selling or renting of any information.
• No access to your contacts or location.

Camera and photos

Runoff Radar asks to use the camera or your photo library only when you add a photo to a room or a test. It gets only the photo you take or pick, and only to use it in the app.

Children

Runoff Radar is a growing tool and is not directed at children under 13. We do not knowingly collect information from children.

Your choices

You can edit or delete any room, test, note or photo in the app at any time. Deleting the app removes everything stored in it.

Changes to this policy

If we change how Runoff Radar handles information, we will update this page and the date at the top before the change takes effect.
