QuicKcals is a food diary at quickcals.com, open to anyone who signs up. It is run as a small UK business by one person. This policy says what is held about you, where it goes, and what you can do about it.
Food and exercise entries (text, photos, estimated calories), body stats you choose to enter (weight, height, age, activity level), weigh-in history, and, if you connect a WHOOP account, daily calorie burn data from WHOOP's API.
All data is stored in a private database on the app's own hosting infrastructure. Your diary is not sold, and it is never given to an advertiser. Nothing you log — no food, photo, weight or figure — is used to target advertising, on this app or anywhere else.
Photos and text may be sent to Anthropic's API to estimate calorie content. Food names you search for may be sent to food databases (Open Food Facts, Nutritionix, USDA) to look up published nutrition figures. If a WHOOP account is connected, calorie burn data is retrieved from WHOOP's API using OAuth authorization you explicitly grant, and can be revoked at any time from WHOOP's own account settings or by disconnecting within this app.
Paid subscriptions are handled by Stripe. Card details are entered on Stripe's own pages and never reach this app — it stores only Stripe's identifier for your subscription and whether it is active.
Free accounts see advertising supplied by Google AdSense, which is what pays for the free tier. Google sets cookies and may use your IP address and browsing activity to choose which ads to show, as described in Google's own policy for partner sites. Where the law requires it, Google's consent notice appears before any of that happens, and your choice there governs it.
What is not shared is your diary. The app sends Google nothing about you: not what you ate, not your weight, not your account. The only thing that reaches the advertising script is the fact that a page was opened.
On a paid plan no advertising script is loaded at all. It is not hidden — it is never fetched, so nothing is set and nothing is measured.
If you share an invite link, the person opening it is shown your username so they can see who invited them. Nothing else about your account is disclosed, and a code that isn't recognised discloses nothing at all.
An account created from an invite records who invited it, so the reward can be paid when the first payment is made. That record is not used for anything else.
The home page lists features that don't exist yet and lets you tap the ones you'd use. That doesn't require an account, and it records only which feature was tapped — no name, no IP address, and nothing that identifies you.
Your browser generates a random id for itself and stores it locally, so that one browser can't count twice for the same feature. It isn't linked to you, it isn't shared with anyone, and clearing your site data discards it.
If you also give an email address to be told when something lands, that address is stored against the features you picked and used for that and nothing else — no newsletter, no advertising, and never passed on. Reply to any of it, or email hello@quickcals.com, and it's deleted.
You can ask for a copy of everything held about you — Settings → Export produces it directly, as a file, without asking anybody. You can ask for it to be corrected, or erased. Deleting your account from Settings erases the diary with it.
Account holders can delete individual entries at any time within the app. For full account or data deletion requests, email hello@quickcals.com.
