Privacy Policy
Updated July 19, 2026
The short version: in guest mode your data never leaves your device. With an account, we store only what the service needs to sync your nutrition data. We show no ads, we use no third-party analytics or tracking cookies, and we never sell your data.
Guest mode: data stays on your device
Without an account, everything you log — foods, meals, goals, water, weight — is stored locally on your device (browser local storage on the web, app storage on mobile). We cannot see or access it. Clearing your browser data or uninstalling the app deletes it. If you later create an account, the app offers to transfer your local data to your account; nothing is uploaded without that explicit step.
What we store with an account
•
Account data: your email address and sign-in credentials, managed by Firebase Authentication (a Google service). We never see your password.
•
Nutrition data (with an active membership): food logs, custom foods and recipes, favorites, nutrient goals, water intake, and weight entries, stored so they can sync across your devices.
•
Billing data: payments are processed by Stripe. We never receive or store your card number — we keep only your subscription status and a Stripe customer reference.
Where your data lives
Synced data is stored on servers in the European Union (Google Cloud, Belgium region), with Cloudflare in front of the site for delivery and security. Firebase Authentication and Stripe process data under their own privacy policies.
Barcode scans and food data
When you scan a barcode, only the barcode number is sent to our server, which looks it up in our food database and, if needed, in Open Food Facts. Our staple food database is built from USDA FNDDS, a public dataset. No photos or camera data leave your device.
What we don't do
•
No advertising and no ad identifiers.
•
No third-party analytics or tracking cookies.
•
No selling or renting personal data to anyone.
•
Local storage and cookies are used only for your session, theme preference, and locally stored guest data.
Export and deletion
You can export all of your synced data from the app at any time as a portable backup file. To delete your account and all associated data, email us; we will complete the deletion within 30 days. Canceling your membership stops billing but does not by itself delete your data, so you can resubscribe without losing history.
Changes and contact
If this policy changes materially, we will update the date above and notify account holders. Questions or requests: support@kaloris.fit.
