Privacy policy

Emnu is a nutrition journal. You say what you ate, and Emnu turns it into food entries with calories and macros. This page explains what data that involves, where it goes, and what you can do about it.

What Emnu stores

• The meals you log: the text you typed or said, the foods Emnu recognised, servings, calories and macros, and the time.
• Your weights and the date you logged them.
• Your targets and preferences: calories, macros, weight unit, goal weight, and whether you weigh food raw or cooked.
• An anonymous account identifier created on your device. No name, email or phone number is required to use Emnu.

Where it goes

Your journal is stored in a database hosted by Supabase, protected so that only your own account can read or write your rows. The sentence you log is sent to Emnu’s server, which uses OpenAI’s API to turn it into structured foods. Only the meal text is sent for that purpose; your weights, targets and account identifier are not.

If you choose the cloud voice option, audio from the microphone is streamed to OpenAI for transcription while the microphone is open and is not stored by Emnu. The on-device voice option keeps audio on your iPhone.

Analytics

Emnu records product events such as “meal logged” or “weight logged” with PostHog, hosted in the EU, so we can see which parts of the app are used and fix what breaks. These events do not contain the text of your meals, your weights or any nutrition values.

Purchases

Subscriptions are handled by Apple through the App Store. Emnu uses RevenueCat to check whether your subscription is active. RevenueCat receives your anonymous account identifier and purchase receipt data from Apple, and nothing from your journal.

What Emnu does not do

• Sell or share your data with advertisers.
• Rank you against other people or make your data visible to anyone else.
• Give medical advice. Nutrition values are estimates from food databases and language models and can be wrong.

Deleting your data

In the app, open You and choose “Delete account and data”. Every meal, weight and setting is removed from our servers immediately and cannot be recovered. You can also email us and we will delete it for you.

Changes

If this policy changes in a way that matters, the date at the top changes and the app will tell you on next launch.
