Privacy policy
Last updated: November 7, 2026
The short version: your food log is stored in your cimcoer.com account so it's on the phone and the web. The app reads calories burned and weight from Health Connect. Your body profile stays on your phone. You can turn off the copy of your daily calories out and weight to cimcoer.com. There are no ads, no analytics and no data sales.
Overview
This policy covers the CIMCOER Android app and the website cimcoer.com, which share one account. Both are operated by Blackdev. CIMCOER stands for Calories In − Calories Out = Results. It shows today's balance: calories you've eaten minus calories you've burned. This page explains what data we handle, where it goes, and what we don't do.
Information we do not collect
- Analytics, usage statistics, or crash reports sent to any third party
- Advertising identifiers or ad-network data
- Location data
- Contacts, camera, microphone, photos, or files other than a menu PDF you choose to import
- Health Connect data other than calories burned, resting metabolic rate and weight. The app doesn't read heart rate, sleep, steps or any other type.
We do not sell your data or share it with advertisers or data brokers.
Information we handle, and where it goes
| Data | Where it's stored | Where it's sent |
|---|---|---|
| Google account details: account ID, email address, name and profile picture | On the cimcoer.com server, linked to your account | Google and Firebase Authentication, which sign you in. Your Google name is never shown publicly. |
| Food log: what you ate, the amount and the calories | On the cimcoer.com server in your private account. The app also keeps a copy in Health Connect on your phone. | To cimcoer.com, so it syncs between the app and the website. The app also writes it to Health Connect as nutrition records so other health apps you allow can see calories eaten. |
| Foods you enter yourself | On the cimcoer.com server, private to your account | Only to cimcoer.com |
| Calories burned and resting metabolic rate, read from Health Connect | Read on your phone | Used on the phone to work out today's balance. The daily total is copied to cimcoer.com unless you turn this off, as described in the next row. |
| Each day's calories out and last weigh-in | On your phone. Unless you turn it off, also on the cimcoer.com server in your private account. | Sent to cimcoer.com so the website can chart your history. This is on by default. Turn off Settings → Show on cimcoer.com in the app and it stops sending it and deletes what's already on the server. |
| Body profile: sex, birth year, height and weight | On your phone only, in local app storage | Never sent anywhere. It's used on the phone to estimate resting calories with the Mifflin-St Jeor equation. |
| Search queries you type | Not stored | Only to cimcoer.com, to search the food database and your saved foods |
| Restaurant menu links and menu PDFs you import | On the cimcoer.com server. The import is logged with your account to cache results and limit repeat imports. The menu items become entries in the public food database, which doesn't show who imported them. | To cimcoer.com, which reads the menu. If the restaurant's site blocks our server, your phone downloads the PDF itself and uploads it. No account token or personal data is sent to the restaurant's site. |
| Forum display name, threads and posts | On the cimcoer.com server | Public on cimcoer.com. Your display name is shown with your posts, and anyone can read them. |
