Privacy policy
Last updated November 2026
Who we are
Leeno is made by Leeno LLC, a limited liability company registered in Wyoming, United States. Leeno LLC decides what information the app collects and what happens to it, which in data protection law makes it the controller of your data. You can reach us any time at hello@leeno.app.
Who Leeno is for
Leeno is built for adults using or considering GLP-1 medication. You need to be 18 or over to use it: onboarding asks your age and will not let you go further below 18. We do not knowingly collect information from anyone under 18. If you believe someone under 18 has an account, tell us at hello@leeno.app and we will delete it.
What we collect
The information you enter into Leeno: your medication and dose schedule, doses you mark as taken, weight entries, symptom check-ins, meals and their nutrition, your goals, and optional profile details (name, country, age, height, sex). To create your account we also store your email address. If you log a meal by photo or by voice, we also handle that photo or recording. See “Photos and voice notes” below.
How we use it
We use your information to run Leeno for you. We use analytics to understand how the app is used, so we can make it better. We never sell your data or use it for advertising.
Why we are allowed to hold it
In the United Kingdom and the European Union, health information is given extra protection in law, and holding it needs your explicit consent. That is what the consent screen asks you for, and nothing about your health leaves your phone until you agree to it. Your email address is different: we hold that to give you an account and sign you in, because there is no way to provide the app you asked for without it. You can withdraw your consent whenever you like, by deleting your data in Settings.
Photos and voice notes
To turn a meal photo or a voice note into protein and calorie numbers, Leeno sends it to OpenAI, an artificial-intelligence company, which processes it on servers in the United States. Leeno never stores the photo or the recording: once the estimate comes back, only the meal name and the numbers you confirm are saved to your account. If you would rather nothing left your phone this way, you can always log a meal by typing it in, or by scanning a barcode.
Barcode scans
When you scan a barcode, Leeno looks it up in Open Food Facts, a free public food database, and in Leeno’s own shared product catalogue. If the product is in neither, the label details you type in are added to that shared catalogue, so the next person to scan it gets an instant match. The catalogue holds product information only. It never holds your meals, your health data, your name, or anything that identifies you as the person who added it.
Apple Health
If you choose to connect Apple Health, Leeno reads two things from it: your daily step count, and the workouts recorded there (the kind of workout, when it started and how long it lasted). Leeno uses them only to show your movement and to work out whether a day counts as a move day under the goal you set. What Leeno reads from Apple Health stays on your phone. It is not uploaded to your Leeno account or our database, and it is never sent to analytics, to advertisers or to anyone else. Leeno never writes anything to Apple Health. If you choose to share a weekly report, its count of move days may include days counted from Apple Health. You can stop Leeno using Apple Health at any time on the Move goal screen, and remove its access completely in your iPhone’s Settings, under Health, Data Access & Devices.
Where it is stored
Your data is stored in a secure cloud database (Supabase) hosted in the European Union, encrypted in transit and at rest. Access is restricted so that only you, signed in to your account, can read or change your data. The one exception is meal photos and voice notes, which are processed in the United States as described above. The codes we email you to sign in are sent on our behalf by Resend, an email delivery service, which receives only your email address and the code.
Crash reports
If Leeno crashes, the app sends a short technical report so we can fix it: what went wrong, the part of the code that failed, which screen you were on, your app version, the model of your phone and the version of iOS it is running, and your account identifier if you are signed in. Crash reports are handled on our behalf by Sentry, a crash-reporting service, and are stored in the European Union. Before a report leaves your phone it is scrubbed to remove things like email addresses and access tokens. It never contains your meals, your weight, your symptoms, or anything else you have logged, and nothing records what is on your screen. If you delete your account, any crash reports you sent stop being linked to you.
How the app is used
To understand how Leeno is used and make it better, the app records a short list of actions: finishing onboarding and logging a meal, a dose, a weigh-in or a check-in, along with how a meal was logged (by photo, voice, barcode or typing). Each action is sent with your account identifier, your app version, the model of your phone, the version of iOS it is running, and the country you are in. This is handled on our behalf by PostHog, a product analytics service, and is stored in the European Union. Your IP address is not stored. These records never contain what you ate, your weight, your dose, your symptoms, or anything else you have logged, and nothing records what is on your screen. Nothing is sent until you have agreed to the consent screen, and you can turn it off any time in Settings, under “Share usage data”. If you delete your account, these records stop being linked to you.
Your choices and rights
You can view and edit your data in the app any time. You can delete your whole account, your login, your email, and all of your stored data, from Settings, “Delete all my data”. You can also ask us for a copy of everything we hold about you, ask us to correct it, ask us to delete it, ask us to stop using it, and withdraw your consent. To make any of those requests, email hello@leeno.app. If you are unhappy with how we have handled your information, you can complain to your national data protection authority: in the United Kingdom that is the Information Commissioner’s Office, and in the European Union it is the authority in the country you live in.
Data retention
We keep your data for as long as you have an account. When you delete your account, your login, your email, and all of your data are removed from our database.
Not medical advice
Leeno helps you track your own information. It is not a medical device and does not provide medical advice. Always follow the guidance of your own clinician for anything related to your medication or health.
