Terms of service

Please read section 3 (not medical advice, AI predictions and assumption of risk), 14 (limitation of liability), 15 (indemnity) and 17 (disputes, arbitration and class-action waiver) carefully. They limit our liability and the ways disputes can be brought.

1. Who these Terms apply to

These Terms apply to everyone who accesses or uses the Service, whether as an individual, on behalf of a business, organisation or other entity, or on behalf of any government, public authority or agency (each a “user” or “you”). If you use the Service on behalf of an entity, you confirm you’re authorised to accept these Terms for it, and “you” includes that entity. No user, including any government or public body, receives any right, licence or remedy beyond what these Terms expressly grant.

2. Eligibility

You must be at least 18 years old and able to form a binding contract. You may not use the Service if you’ve been barred from it by us or by applicable law.

3. Not medical advice; AI predictions; your responsibility

The Service is a general wellness tool. It is not a medical device and does not provide medical, nutritional or health advice, diagnosis or treatment. Calories, macros, targets, BMI, food recognition and all other information are estimates that may be incomplete or wrong. You are solely responsible for checking what you log and for any decision you make about your diet, weight, exercise or health. Always consult a qualified health professional before changing your diet or if you are pregnant, have a medical condition or have, or have had, an eating disorder. Never ignore professional advice or delay seeking it because of something in the Service. You use the Service at your own risk.

AI food recognition and predictions

The Service uses automated technology, including artificial intelligence, to suggest what food is in a photo, its portion and its nutrition values (“Predictions”). Predictions are automatically generated guesses. They can be, and often will be, wrong: they may identify the wrong food or dish, miss foods, invent foods that aren’t there, misjudge portions, quantities or cooking methods, and cannot see hidden ingredients such as oil, ghee, butter, sugar, salt, sauces, fillings or anything mixed in. The same photo may give different results at different times or on different devices. You acknowledge and agree that:

• Every Prediction is a suggestion only. Nothing is logged until you review it and choose to save it, and you are solely responsible for checking and correcting each food, portion and value before saving and for everything you save.
• Predictions are provided without any promise of accuracy, completeness, consistency or fitness for any purpose, and any accuracy figures, examples or descriptions we publish are illustrative only.
• We are not responsible or liable for any Prediction, for any error in it, or for any decision, action or omission by you or anyone else based on it.
• Recognition is provided by your phone’s manufacturer or operating system (for example Google or Apple) or by third-party AI services (Google’s Gemini API). We don’t control them, and they may change, stop working or behave differently without notice.

Nutrition data and calculations

Nutrition values come from public food databases and user-entered information, and calorie, macro, BMI and target calculations use general formulas. Foods vary by recipe, brand, region, preparation and serving, so every value is an approximation and may contain errors. Custom foods you create are your responsibility. We may correct or change food data at any time; values already in your diary may not be updated.

Allergies, medical conditions and medication

Do not rely on the Service to detect allergens or ingredients, to manage an allergy or intolerance, or to calculate medication doses (including insulin or carbohydrate counting for diabetes), or to manage kidney disease, pregnancy, an eating disorder or any other medical condition. Always read food labels, ask whoever prepared the food, and follow your health professional’s instructions. If you think you may have a medical emergency, contact your doctor or local emergency services immediately.

Device compatibility and recognition accuracy

On phones with built-in AI, food recognition runs on the phone: iPhone 15 Pro and newer, with Apple Intelligence turned on and the latest iOS (when the iPhone app launches); Android phones with Google’s built-in on-device AI, including Google Pixel 9 and newer, Samsung Galaxy S26 series and the latest Galaxy Z foldables, OnePlus 13 and newer, and recent flagships from Xiaomi, POCO, OPPO, vivo, iQOO, Honor, Motorola, realme, Sony, Sharp and Lenovo. Supported Android phones are listed on our home page, based on the manufacturer’s published list, which may change. On all other devices, and when a phone’s built-in AI can’t read a photo, the Service uses cloud recognition, which needs an internet connection (see our privacy policy). Recognition on any device may be wrong or incomplete, and features available on a device may change with its operating system, manufacturer, region or settings. We do not guarantee that any feature, level of accuracy or device will be supported.

Reminders, streaks and your records

Meal reminders, streaks, charts and backups are conveniences. Reminders may be delayed or not delivered (for example because of your phone’s battery, notification or time settings), and data may be lost, delayed or not synced. Keep your own copy of anything important to you.

Assumption of risk and release

You understand that changing what you eat, how much you eat or how much you exercise carries risks, including risks to your physical and mental health. You voluntarily assume all such risks, and all risks arising from Predictions, nutrition data, calculations or any other content of the Service, whether or not they are accurate. To the maximum extent permitted by law, you release CalMeter and its owners, employees, contractors, agents, suppliers and licensors from all claims, demands and damages of every kind, known and unknown, arising out of or relating to those risks, Predictions, content or your use of the Service. If you are in California, you waive California Civil Code section 1542 (and any similar law elsewhere), which says: “A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party.”

No professional relationship (such as doctor–patient or dietitian–client) is created by your use of the Service or by contacting us.

4. Your account

• Give accurate information and keep it up to date.
• You’re responsible for everything that happens in your account and for keeping your phone, Google account and mobile number secure.
• One account per person; accounts may not be shared, sold or transferred.
• You may delete your account at any time (Profile → Delete account, or here). Deletion is permanent and cannot be undone.

5. Licence

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to use the app on devices you own or control, solely for your own personal, non-commercial use. All rights not expressly granted are reserved.

6. Acceptable use

You agree not to, and not to help anyone else to:

• copy, modify, distribute, sell, rent, lease or sublicense any part of the Service;
• reverse engineer, decompile, disassemble, extract models or data from, or otherwise try to derive the source code, models, algorithms, databases or methods of the Service, except where the law expressly allows it despite this restriction;
• use modified, tampered or unofficial versions of the app, or circumvent any security or usage limits;
• scrape, crawl or harvest data, use bots or automated means, or use the Service or its outputs to build, train or improve a competing product or any AI model;
• access other people’s accounts or data, or our systems, without permission;
• abuse sign-in, for example by requesting codes for numbers that aren’t yours;
• interfere with or disrupt the Service or its infrastructure;
• use the Service for any unlawful, harmful or fraudulent purpose, or in breach of these Terms.

7. Free scans, CalMeter Premium and billing

Free use and scan limits

Searching for foods, logging them manually, custom foods, your diary, targets, progress and reminders are free and unlimited. AI food scanning includes a limited number of free scans per account (currently 3, counted when a scan recognises food, on any device); after that, scanning requires CalMeter Premium. Free scans are per account and don’t reset when you reinstall the app or change phones.

What CalMeter Premium includes

• AI food scanning. On phones where recognition runs on the phone’s built-in AI, scans are not limited by us. On other phones, and when the built-in AI can’t read a photo and cloud recognition is used, scans are limited per day (currently up to 10, refreshed at midnight in your time zone).
• No ads, once ads are shown to free users.

Premium is for your personal use with your CalMeter account, on any phone where you sign in to that account. We may apply reasonable limits to prevent abuse or automated use, and we may change what Premium includes, the free scan allowance or the daily limits, with notice where required by law. Scan limits never affect searching and logging foods manually.

Prices, billing and automatic renewal

• Premium is sold as a monthly or a yearly subscription through Google Play (and the App Store once the iPhone app launches). The price, the billing period and any taxes are shown in the app and by the store before you buy. Prices may differ by country and currency.
• Payment is charged to your store account when you confirm the purchase. Your subscription renews automatically at the end of each period, at the then-current price, unless you cancel it before the renewal date.
• If we offer a free trial or an introductory price, its length and terms are shown before you start. Unless you cancel before the trial or introductory period ends, it converts to a paid subscription at the regular price.
• If we change the price of a subscription, you’ll be told in advance as required by the store and the law; where consent is required, the new price applies only if you accept it.

Cancelling, refunds and payment problems

• You can cancel at any time in your store account (on Android: Play Store → Profile → Payments & subscriptions → Subscriptions). We can’t cancel a subscription for you.
• After you cancel, Premium stays active until the end of the period you’ve paid for; it then ends and isn’t renewed. There are no partial refunds for unused time, except where the store’s policy or the law requires otherwise.
• Refunds are handled by the store under its refund policy. If a purchase is refunded or charged back, Premium ends immediately.
• If a renewal payment fails, the store may give you a grace period to fix it, during which Premium may continue; if payment isn’t fixed, Premium is paused or ends.
• Deleting your CalMeter account doesn’t cancel your subscription. Cancel it in your store account first, so you aren’t charged again.
• If you reinstall the app or change phones, sign in to the same account and use Restore purchases to get Premium back.

8. Your content

You keep ownership of the information you log. You grant us a worldwide, non-exclusive, royalty-free licence to host, store, process and display it only as needed to provide the Service to you, as described in our privacy policy. You’re responsible for the information you provide.

9. Feedback

If you send us ideas or feedback, you grant us a perpetual, irrevocable, royalty-free right to use them for any purpose without obligation to you.

10. Our intellectual property

The Service, including its software, models, food database and its selection and arrangement, design, text, graphics, logos and the CalMeter name, is owned by us or our licensors and protected by intellectual property laws. Third-party data is used under its own licences (see credits). You may not use our name, logo or brand without our written permission.

11. Third-party services

The Service relies on third-party services such as app stores, sign-in providers, cloud hosting, AI services (Google’s Gemini API) and your phone’s operating system. Their terms and privacy policies apply to your use of them, and we’re not responsible for them.

12. Changes, availability and termination

We may change, suspend or discontinue any part of the Service at any time, and we don’t guarantee it will be available, uninterrupted or error-free. We may suspend or terminate your access at any time, without notice, if you breach these Terms, if required by law, or to protect the Service, users or us. Sections that by their nature should survive termination (including 3, 8 to 10 and 13 to 19) survive it.

If we terminate your access because you breached these Terms, you won’t receive a refund for any unused subscription time. If we discontinue the Service or Premium for everyone, we’ll give notice where we can and, where the store’s policy or the law requires it, arrange a pro-rata refund of prepaid time.

13. Disclaimer of warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, TITLE AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT ANY NUTRITIONAL INFORMATION, ESTIMATE, CALCULATION, TARGET, FOOD RECOGNITION, PREDICTION OR SUGGESTION IS ACCURATE, COMPLETE, CURRENT OR RELIABLE, THAT THE SERVICE WILL MEET YOUR REQUIREMENTS OR ACHIEVE ANY RESULT (INCLUDING ANY WEIGHT OR HEALTH RESULT), OR THAT IT IS FREE OF ERRORS, VIRUSES OR OTHER HARMFUL COMPONENTS. YOU ALONE ARE RESPONSIBLE FOR ANY DAMAGE TO YOUR DEVICE OR LOSS OF DATA RESULTING FROM YOUR USE OF THE SERVICE.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW: (A) CALMETER AND ITS OWNERS, EMPLOYEES, CONTRACTORS, AGENTS, SUPPLIERS AND LICENSORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR FOR ANY PERSONAL INJURY, ILLNESS, ALLERGIC REACTION, WEIGHT CHANGE OR OTHER HEALTH OUTCOME ARISING FROM OR RELATING TO ANY PREDICTION, INCORRECT OR MISSING FOOD RECOGNITION, NUTRITION VALUE, CALCULATION, REMINDER, OR YOUR RELIANCE ON THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES; AND (B) OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID US FOR THE SERVICE IN THE 12 MONTHS BEFORE THE CLAIM AND INR 1,000 (OR USD 15). These limits are an essential basis of the bargain between you and us; without them we could not offer the Service. They apply to every theory of liability, including contract, tort (including negligence), strict liability and statute, and even if a remedy fails of its essential purpose. Nothing in these Terms excludes liability that cannot be excluded under applicable law.

15. Indemnity

To the maximum extent permitted by law, you will defend, indemnify and hold harmless CalMeter and its owners, employees, contractors, agents, suppliers and licensors from any claims, liabilities, damages, losses and expenses (including reasonable legal fees) arising out of or relating to your use of the Service, your reliance on any Prediction or content, food you or others eat based on the Service, your content, your breach of these Terms, or your violation of any law or the rights of any third party. This includes claims brought by anyone you share the Service or its results with, such as family members or people you cook for.

16. Time limit for claims

To the extent permitted by law, any claim relating to the Service must be brought within one (1) year after it arises; otherwise it is permanently barred.

17. Disputes, arbitration and class-action waiver

Informal resolution first. Before starting any proceeding, you agree to email us at info@calmeter.app with a description of the dispute and try in good faith to resolve it for at least 60 days.

Binding arbitration. To the extent permitted by law, any dispute that isn’t resolved informally will be finally resolved by binding arbitration before a sole arbitrator appointed under the Arbitration and Conciliation Act, 1996 (India). The arbitration will be conducted in English, the seat will be in India, and it may be conducted online or on written submissions. Each party bears its own costs unless the arbitrator decides otherwise.

No class or representative actions. To the extent permitted by law, disputes will be resolved only on an individual basis. You waive any right to bring or take part in a class, collective, consolidated or representative action or arbitration, or to act as a private attorney general, and the arbitrator may not consolidate claims or award relief on behalf of anyone other than you.

Waiver of jury trial. To the extent permitted by law, you and we each waive any right to a jury trial.

Either party may seek urgent interim relief from a competent court to protect intellectual property or prevent irreparable harm.

18. Governing law

These Terms and any dispute relating to the Service are governed by the laws of India, without regard to conflict-of-law rules. Subject to section 17, the courts in India have exclusive jurisdiction. If you’re a consumer, you keep any protections of the law where you live that cannot be waived by contract.

19. General

• Entire agreement. These Terms and the privacy policy are the entire agreement between you and us about the Service.
• Severability. If any provision is found unenforceable, it will be limited to the minimum extent necessary and the rest remain in full effect.
• No waiver. Our failure to enforce a provision isn’t a waiver of it.
• Assignment. You may not assign or transfer these Terms; we may assign them, including as part of a merger, acquisition or sale of assets.
• Force majeure. We’re not liable for delays or failures caused by events beyond our reasonable control.
• App stores. Where required by an app store, these Terms are between you and us only, not the store, and the store has no obligation to provide support or maintenance.
• Changes to these Terms. We may update these Terms. We’ll change the date above and, for material changes, notify you in the app. Continuing to use the Service after the change means you accept it.
