Privacy policy

Last updated 15 November 2026

Who we are

IBS & FODMAP Tracker (“the app”) is made by Nozza (“we”, “us”). For anything to do with privacy, email tim@nozza.co.

Information the app stores on your iPhone

Everything you log stays in the app’s private storage on your device:

• bowel movements, symptoms and their severity, meals and the tags you add, medication and doses;
• sleep, stress, exercise, water, cycle day and notes;
• meal photos you choose to take or add;
• your FODMAP plan progress and test results;
• your settings, such as reminder times.

This is health information, which data protection law treats as special-category data. We do not collect it, see it or process it on our systems. It is protected by your iPhone’s own encryption, and you can add Face ID or passcode lock in the app’s settings.

Backups and exports

You can export your diary as a backup file or spreadsheet, or create a PDF report. The app hands the file to the iPhone share sheet, and you choose where it goes, for example Files, email or AirDrop. Once a file leaves the app, the place you send it is responsible for it.

The app does not write your diary to iCloud. Your iPhone’s own device backup, if you have it turned on, may include the app’s data, in the same way it includes other apps. You control this in your iPhone’s settings.

Reminders

Reminders are local notifications scheduled on your iPhone. No reminder content is sent to us or to any notification service.

Purchases

Pro subscriptions and the lifetime purchase are processed by Apple through the App Store. Apple’s privacy policy applies to the payment. We use RevenueCat to confirm whether your device has an active purchase. RevenueCat receives a random identifier for the app installation and the purchase receipt from Apple. It does not receive your name, email address or any diary content.

When you contact us

If you email us, we receive your email address and whatever you write. We use it only to reply to you, and delete support emails within 24 months. The app’s “Contact support” button adds the app version and device type only, never diary data. Please don’t send us health details you don’t need to.

Analytics and advertising

The app contains no advertising, no advertising identifiers and no third-party analytics or tracking. If we ever add anonymous usage counts, they will never include diary content, and we will update this policy and ask for your consent first where the law requires it.

Permissions the app asks for

• Notifications, for the reminders you turn on.
• Camera and photos, only when you add a meal photo.
• Face ID, only if you turn on app lock.

You can change any of these in your iPhone’s Settings app.

This website

This website is hosted by Vercel. Like most hosts, Vercel processes your IP address and basic request information to deliver pages and keep the service secure. The site sets no cookies and uses no analytics or tracking.

Your rights

Under UK and EU data protection law you can ask to access, correct or delete personal data we hold about you, or object to how we use it. Because your diary never reaches us, you can view, export and delete it yourself at any time in the app. Settings → Delete all data removes everything from your device. To ask about anything else we hold, such as support emails, contact tim@nozza.co.

If you are unhappy with how we have handled your information, you can complain to the Information Commissioner’s Office at ico.org.uk.

Children

The app is intended for adults aged 18 and over.

Changes to this policy

If we change how the app handles information, we will update this page and the date at the top. We will tell you in the app about any significant change before it takes effect.
