Terms of use

Effective August 18, 2026.

By using ZenCal you agree to what is written here. It is deliberately short: if any part is unclear, write to support before subscribing.

What you get

A personal, non-exclusive, non-transferable licence to use the app on your devices. The app, the brand and the content remain ours.

An estimate is not a measurement

The numbers ZenCal shows for a photographed plate are a vision model’s estimate. They are wrong sometimes — too high, too low. Packaged food scanned by barcode or label comes from public databases, which can also carry entry errors.

ZenCal is not a medical device, does not diagnose and does not replace a health professional. Nothing in the app is medical or nutritional advice. If you have or have had an eating disorder, or you are in treatment that involves diet control, talk to whoever follows your care before using any calorie counter — this one included.

Subscription

• Premium is sold as a monthly or annual subscription, charged by Apple or Google depending on the store you downloaded from.
• The trial period is three days. Cancel before it ends and nothing is charged.
• The subscription renews on its own at the end of each cycle unless you cancel at least 24 hours before renewal, in your store account settings.
• Prices appear in your currency inside the app before confirmation, and can change — a price change applies from the following cycle and is announced by the store.
• Refunds are handled by the store under its own policy. We cannot process a refund outside of it.

What you send

Your photos stay yours. By sending them, you grant us permission to process and store them for the single purpose of providing the service — analyzing the plate and showing you your history. We do not use your photos to train models, do not publish them and do not pass them on for marketing.

Acceptable use

Do not try to circumvent the subscription, bulk-extract the database, overload the service or use the app for anything illegal. We may suspend access for anyone who does.

Availability

We do our best to keep the service up, but we do not promise uninterrupted availability. Features may change or be removed, and a relevant change is announced inside the app.

Limitation of liability

To the extent permitted by law, our total liability for any claim related to the app is limited to what you paid for the subscription in the previous twelve months. We are not liable for dietary decisions made from the app’s numbers — they are estimates, and decisions about your food are yours and your care team’s.

Governing law

These terms are governed by Brazilian law, with the consumer’s domicile as the venue for any dispute.
