Privacy policy
1. Who we are
Minthe is an iOS app provided by Vitaloom LTD. For any privacy question, or to ask us to delete something, email support@vitaloom.xyz.
2. What stays on your device
Everything you log. Meals, symptoms, stool entries, notes, photos, lab results, trial and program history. It is stored locally, and if you turn on sync it goes to your own private iCloud container, which is governed by your Apple account and which we have no access to.
There is no Minthe account. We do not ask for your name, email address or a login, so we hold no profile to attach your diary to.
3. AI scans, and what we keep
This is the one part of the app where data leaves your device, so it is worth being precise.
When you scan a meal photo, a packaged label, or a lab report, the image is sent over an encrypted connection to our processing service on Cloudflare, and on to Google's Gemini model, which returns a structured list of foods, ingredients or analytes. This only happens when you tap scan. If you type your entries instead, nothing leaves your device.
What we do not keep: the image itself. It is passed through for processing and is not written to storage by us.
What we do keep, in a request log:
- the list of food or ingredient names the model returned, with any quantity and nutrition values, and which of them were missing from our on-device catalogue
- a random identifier generated by the app on first launch, which is not linked to your name, email or Apple ID
- technical metadata: a request ID, timestamp, request size, processing time, model token usage and estimated cost
We keep this to find foods missing from our catalogue, to spot cases where the scan misreads something, to enforce fair-use limits, and to monitor what the service costs to run. We do not use it to advertise to you and we do not sell it.
These logs are deleted within 12 months. Because the identifier is random and app-generated, we can only find and delete your entries if you send it to us, so please include it if you ask.
4. Apple Health
If you grant permission, Minthe reads sleep, resting heart rate, steps and menstrual cycle from Apple Health so those can be weighed alongside food. This is read on your device for context only and is not sent to us. You choose which categories to grant and can revoke any of them in the Health app at any time.
5. Subscriptions
Purchases are handled entirely by Apple. We never see your card details, billing address or Apple ID. We receive only the confirmation that an entitlement is active.
6. What we do not do
- We do not sell your data or share it with data brokers.
- We do not show ads, and the app contains no advertising or analytics SDKs.
- We do not build advertising or health profiles about you.
- We do not require an account to use the app.
7. Your rights and deleting your data
Your logs are yours. Export them as CSV or PDF at any time, delete them in the app, and remove the local copy by deleting the app. If you used iCloud sync, remove the Minthe data from your iCloud settings as well.
Depending on where you live you may have rights to access, correct, delete, or restrict processing of personal data we hold. Since the only thing we hold is the scan log described in section 3, those requests are about that log. Email support@vitaloom.xyz and we will respond as required by applicable law.
8. Children
Minthe is not directed at children and is not intended for anyone under 16. We do not knowingly collect data from children. If you believe a child has used the app, contact us and we will help remove anything associated with it.
9. Security
Data in transit is encrypted. Data on your device is protected by iOS, and iCloud data by your Apple account. No system is perfectly secure, and we would rather say so than imply otherwise.
10. Changes
If we change this policy we will update the date at the top of this page, and for anything significant we will say so in the app.

Frequently asked
Do you have a copy of my food and symptom diary?
No. Your diary is stored on your device and syncs only through your own private iCloud, which we cannot read. There is no Minthe account and no server-side copy.
Do you store my meal photos?
No. The image is passed through for processing and is not written to storage by us. What is kept is the list of food names the model returned from it.
What is the random identifier you keep?
A UUID the app generates on first launch and stores on your device. It is not derived from and not linked to your name, email, Apple ID or device serial. It exists so we can apply fair-use limits and group request logs.
Can I use Minthe without anything leaving my device?
Yes. Type your entries rather than scanning them and nothing is sent to us at all. Every feature except the AI scans works entirely on device.
How do I delete everything?
Delete your data in the app and delete the app to remove the local copy. If you used iCloud sync, also remove Minthe data in your iCloud settings. To have your scan logs removed, email us with the identifier from the app's settings screen.
