Get in touch

Email warren@overstacked.io. It reaches a person, and you can expect a reply within two working days.

If you’re reporting something that looks wrong, the most useful thing you can send is the exact line you typed and the number the app showed next to it. That’s usually enough to find it.

A line shows a dash instead of a number

That’s deliberate. Macro Notes only prices a line when the words you wrote name a food it actually holds measured data for — it will never invent a figure to fill the gap. A dash means one of three things:

• the food isn’t in the catalogue yet — email us the line and we’ll look at adding it;
• the line names more than one food (eggs, butter) — put them on separate lines;
• the amount couldn’t be applied (a tuna sandwich measured in millilitres) — the number goes red rather than being quietly rounded to something plausible.

The subscription

The AI assistant is the only paid part of the app. Everything else — the diary, the catalogue, meals, scanning and the dashboard — is free and stays that way.

To cancel, open Settings in the app and tap the Subscription row, which opens the screen for cancelling, changing plan or asking for a refund. You can also go to Settings → your name → Subscriptions on your iPhone. Cancelling at least 24 hours before the period ends stops the next renewal; you keep access until the period you’ve paid for runs out.

To restore a purchase on a new phone, open the assistant and tap Restore on the subscription screen. Your subscription follows your Apple Account, so signing in with the same one is all that’s needed.

Refunds are handled by Apple, not by us — we can’t issue one, and we never see your payment details. Request one at reportaproblem.apple.com. Tell us as well if something went wrong; we’d rather know.

Your account and your data

Signing in uses Sign in with Apple and asks for no scopes at all — not your name, not your email address. Your diary itself never leaves your phone.

You can delete your account and everything attached to it from within the app, under Settings → Delete Account. It is immediate and it cannot be undone. To ask for a copy of what we hold, or to have it corrected, write to warren@overstacked.io. The Privacy Policy sets out the whole of it.

Where the food data comes from

Generic foods come from the UK’s Composition of Foods Integrated Dataset (CoFID) and USDA FoodData Central; branded products come from Open Food Facts, which is transcribed from packaging by the public and is occasionally wrong. If a product’s figures look off, send us the barcode.

The figures are estimates of what you ate, not measurements of it, and the app is a food diary rather than a medical device — see the Terms of Use.

Requirements

Macro Notes runs on iPhone with iOS 26.2 or later. Pricing a line needs a network connection; without one the app falls back to a small set of foods stored inside the app, and shows a dash rather than a guess for anything it can’t reach.
