Cal.AI — AI calorie & food tracker · Android app on Google Play (package com.moyo.calories) · Last updated: October 3, 2026
These Terms of Service ("Terms") are an agreement between you and yuepengjie, the developer that
publishes the Cal.AI Android app on Google Play ("Cal.AI", "we", "us"). They govern your use of the Cal.AI Android app and
the Cal.AI service at cal.moonga.me that the app talks to (together, the "Service"). By installing or using the app you
agree to these Terms. If you do not agree, do not use the Service.

until you cancel in Google Play. See Section 4.
Cal.AI shows no third-party advertisements.
1. Who can use Cal.AI
You must be at least 16 years old. If you are under the age of legal majority where you live, you may use the Service
only with the permission of a parent or legal guardian who accepts these Terms on your behalf.
The Service is for your personal, non-commercial use.
2. The Service
Cal.AI is a calorie and nutrition tracker. It lets you:
photograph a meal and receive an AI-generated estimate of its calories, protein, carbohydrates and fat;
scan a product barcode, search a nutrition database, or enter foods manually;
keep a food diary and weight log and view your progress;
get daily calorie and macro targets calculated from the answers you give during setup, and optionally follow a
carb-cycling plan;
receive meal reminders and other notifications you have allowed.
Cal.AI does not show third-party advertisements. We may add, change or remove features over time, and the Service may
occasionally be unavailable for maintenance or reasons outside our control.
3. Your account
Sign-in. Finishing setup and saving your plan requires signing in with your Google account. Cal.AI does
not create a separate password; your Cal.AI account is tied to the Google account you sign in with, and you are
responsible for keeping that Google account secure.
Accurate information. The targets Cal.AI calculates depend on the information you provide (such as
age, height, weight and activity level). Please provide accurate information and keep it up to date.
Signing out. You can sign out at any time in Settings. Data stored on your device, such as your food
diary, stays on the device.
Deleting your account. You can delete your account at any time in the app (Settings › Delete account)
or by following the steps at cal.moonga.me/delete-account.html.
What is deleted and what is kept is described in the Privacy Policy. Deleting your account or uninstalling the
app does not cancel a Google Play subscription — cancel it in Google Play first (Section 4).
4. Cal.AI Pro subscription and payments
4.1 What is free and what is paid
You can use Cal.AI without paying. Logging by barcode, food search and manual entry and the food diary are available
without a subscription, together with a limited number of free AI photo scans. Cal.AI Pro is an optional
paid subscription that removes the limit on AI photo scans. The benefits included in Pro are those described on the
purchase screen at the time you subscribe.
4.2 Billing
Subscriptions are sold and billed by Google Play using Google Play's billing system. We do not
receive or store your payment card details.
Cal.AI Pro is offered with monthly and yearly billing periods and, where shown, a 3-month billing period. The price,
currency and billing period of each plan are shown on the purchase screen before you confirm, and applicable taxes may
be included or added by Google Play.
Payment is charged to your Google Play payment method when you confirm the purchase or, if you start with a free
trial, when the trial ends.
4.3 Automatic renewal
Your subscription renews automatically at the end of each billing period, for the same period and at
the then-current price, until you cancel it. Renewal payments are charged to your Google Play payment method.
4.4 Free trial
A free trial may be offered to new subscribers that Google Play reports as eligible. The length of the trial and the
price that will be charged when it ends are shown by Google Play before you confirm the purchase. If you do not cancel
before the trial ends, you are charged the plan price and the subscription renews automatically as described
above. Eligibility for a free trial is determined by Google Play.
4.5 How to cancel
Open the Google Play app › tap your profile picture › Payments & subscriptions › Subscriptions ›
Cal.AI › Cancel subscription, or go to
play.google.com/store/account/subscriptions.
Cancel before the end of the current billing period (or free trial) to avoid being charged for the next one.
After you cancel, Pro stays active until the end of the period you have already paid for; it then stops and you
are not charged again.
Uninstalling the app, signing out or deleting your Cal.AI account does not cancel the subscription.
4.6 Refunds
Purchases are processed by Google Play, and refunds are handled under
Google Play's refund policies. Except where Google Play's
refund policies or the law give you a right to a refund, payments are non-refundable. Cancelling does not refund the
current billing period; you keep Pro until that period ends (Section 4.5). If something went wrong with a purchase, email us at
kirbyyue@gmail.com and we will help.
4.7 Price changes and restoring purchases
If we change the price of a subscription, you will be notified in advance through Google Play, and, where Google
Play requires it, the new price applies only after you accept it.
A subscription is linked to the first Cal.AI account that activates it. If you reinstall the app or change device,
sign in with the same account and use Restore purchases in Settings.
5. Health and nutrition disclaimer
Not medical advice, not a medical device. Cal.AI provides general nutrition and wellness information
only. It does not diagnose, treat, cure or prevent any disease or condition and is not a substitute for advice from a
doctor, dietitian or other qualified professional.
Estimates. Calorie and nutrient values, daily targets, goal dates and weight projections are
estimates. Results from photos depend on the image, the portion size and how the food was prepared, and individual
results vary. We do not promise any particular weight or health outcome.
Talk to a professional first before making significant changes to your diet or activity, especially
if you are pregnant or breastfeeding, are under 18, have a medical condition such as diabetes, take medication, or have
or have had an eating disorder.
Allergies and food safety. Cal.AI does not detect allergens and cannot tell you whether a food is
safe for you. Always check ingredients and labels yourself.
Do not use Cal.AI for extreme dieting. If you feel unwell, or your weight is outside a healthy
range, stop and seek professional advice.
Emergencies. Cal.AI cannot detect or respond to a medical emergency. If you think you are having
one, contact your local emergency services immediately.
6. AI-generated results
Food recognition and nutrition estimates from photos are produced by artificial intelligence and can be wrong: foods
may be misidentified and portions misjudged. Review each result and correct it with Fix results where needed
before relying on it. You are responsible for decisions you make based on the information in the app.
7. Your content
"Your content" means the food photos, food names, barcodes, diary entries and profile answers you submit.
You keep all rights in your content. You give us permission to process it only as needed to provide the Service to
you — for example, sending a food photo to our AI processing provider to produce an estimate — as described in the
Privacy Policy. We do not publish your content, sell it, or share it with other users.
Only submit content you have the right to use, and do not submit anything unlawful.
8. Acceptable use
You agree not to:
use the Service for any unlawful purpose or in breach of these Terms;
copy, modify, decompile or reverse engineer the app, except where the law allows this despite these Terms;
access the Service by automated means, scrape it, or call our servers other than through the app;
bypass or attempt to bypass scan limits, subscription checks or security measures;
interfere with or overload the Service, or attempt to gain unauthorized access to it or to other users' data;
resell, rent or commercially exploit the Service.
9. Health information
Cal.AI uses only the health-related details you enter yourself, such as your weight and any health conditions or
allergies you select, and does not connect to other health apps. How this information is used, stored and retained is
described in the Privacy Policy.
10. Third-party services and links
The Service relies on services provided by others, including Google Play (distribution and billing), Google Sign-In,
Firebase and OpenAI (which analyzes the food photos you submit, as described in the Privacy
Policy), and it may link to third-party websites such as public health information pages. Those
services and sites are governed by their own terms and privacy policies, and we are not responsible for them. Your use
of Google Play is also subject to the Google Play Terms of Service.
11. Intellectual property and licence
The app and the Service, including their software, design, text and graphics, belong to us or our licensors and are
protected by law. Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable
licence to install and use the app on Android devices you own or control. All rights not expressly granted are
reserved. If you believe something in the app infringes your rights, contact us at
kirbyyue@gmail.com.
12. Suspension and termination
You may stop using the Service at any time and may delete your account as described in Section 3.
We may suspend or end your access if you seriously or repeatedly breach these Terms, if we are required to by law,
or if we discontinue the Service. Where reasonable we will give you notice.
If we discontinue the Service, we will stop future renewals of active subscriptions. If you have paid for a period
that runs past the discontinuation date, you may request a refund for the unused part through Google Play or by
emailing us.
Sections that by their nature should continue after termination (including Sections 5, 13, 14 and 15) continue to
apply.
13. Disclaimer of warranties
To the fullest extent permitted by law, the Service is provided "as is" and "as available", without warranties of any
kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose and
non-infringement. We do not warrant that the Service will be uninterrupted, error-free or accurate.
14. Limitation of liability
To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential or
punitive damages, or for loss of data, arising from your use of the Service, and our total liability for any claim
relating to the Service is limited to the amount you paid for the Service in the 12 months before the claim arose.
Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, or any
rights you have under the mandatory consumer protection laws of the country where you live.
15. Indemnity
To the extent permitted by law, you agree to compensate us for losses and reasonable costs arising from your breach of
these Terms or your unlawful use of the Service.
16. Changes to these Terms
We may update these Terms from time to time. We will post the updated version on this page and change the "Last
updated" date. If the changes are significant, we will notify you in the app. If you continue to use the Service after
the updated Terms take effect, you accept them; if you do not agree, stop using the Service and cancel any subscription.
17. General
These Terms and the Privacy Policy are the entire agreement between you and us about the Service.
If any part of these Terms is found to be unenforceable, the rest remains in effect.
If we do not enforce a provision, that is not a waiver of our right to do so later.
You may not transfer your rights under these Terms without our consent.
