Terms of Service
Effective 31 July 2026
Please read these Terms of Service ("Terms") carefully before using the Kally mobile application (the "App") operated by Kally ("we", "us", or "our").
The parts people miss
Subscriptions renew automatically until you cancel them in your App Store or Play Store account. Cancelling is something only you can do, from there — not something we can do for you, and not something deleting the app does.
Kally is not a medical device and gives no medical advice.
Nutrition figures and bloat scores are estimates, not measurements — built to show you patterns over time, not to be clinically precise.
If you are in the United States, section 14 requires most disputes to go to individual arbitration rather than to court, and waives class actions. You can opt out within 30 days.
1. Acceptance of Terms
By downloading, installing, accessing or using the App, you agree to be bound by these Terms. If you do not agree to them, do not use Kally.
2. Description of Service
Kally estimates the nutritional content of meals you photograph, scores each day for the factors that move water retention, tracks the daily routines you choose to keep, and produces targets and suggestions from those readings and the details you give us. It is a general wellness and self-tracking tool.
Nutrition estimates and scores are produced automatically by a model rather than reviewed by a person.
3. Eligibility
You must be at least 16 — or at least 13 where your country's law allows it with a parent or guardian's consent — and old enough to enter into a contract where you live. If you are using Kally with a guardian's consent, that guardian accepts these Terms with you.
4. Your Account
Kally requires an account. You are responsible for keeping your credentials safe and for everything done through your account. Tell us at support@kally.app if you think someone else has access to it. One account is for one person: do not share it, sell it, or let anyone else use it.
5. Subscriptions and Payments
5.1 Subscription Plans
Kally offers subscription plans with different billing periods (weekly or yearly). Subscription details, including pricing and features, are displayed in the App.
5.2 Free Trials
No free trial is offered at present. Where one is offered, it converts to a paid subscription at the end of the trial unless you cancel before it ends, and trials are limited to one per store account. Any unused part of a trial is forfeited when you buy a subscription.
5.3 Auto-Renewal
Your subscription renews automatically for the same period at the same price unless you turn off auto-renew at least 24 hours before the current period ends. Your account is charged for renewal within 24 hours of the end of the period.
5.4 Cancelling
Cancel in your platform account settings — "Manage Subscription" in the App opens that screen for you. Deleting the App does not cancel anything, and neither does deleting your Kally account. Cancelling stops the next renewal; you keep access until the end of the period you have already paid for.
5.5 Payment Processing
All payments are processed by Apple (for iOS) or Google (for Android) through their respective app stores. We do not process payments directly, and we never see or hold your card details.
5.6 Refunds
Refunds are handled by Apple or Google under their own policies. We cannot issue them ourselves, though we will gladly support a request you make to them. Except where the law requires otherwise, payments are non-refundable and there is no refund for a partly used period.
5.7 Subscription Transfer
Subscriptions are tied to the App Store or Play Store account that bought them and cannot be transferred between platforms or between different store accounts.
5.8 Restoring Purchases
You can restore a previous purchase from within the App, which returns access to your subscription on a new device or after reinstalling.
5.9 Price Changes
We may change prices. A change applies from your next renewal, never retroactively, and you will be told in advance and given the chance to cancel. Where the platform requires your explicit consent to a rise, your subscription will not renew at the new price without it.
5.10 UK and EU Consumers — 14-Day Right to Withdraw
You normally have 14 days to withdraw from a distance contract. By subscribing and getting immediate access to the paid features, you ask us to begin performance straight away and acknowledge that you lose that withdrawal right once the service has been fully performed. Where the right still applies, exercise it through the store you bought from.
6. Health Disclaimer
6.1 Not a Medical Device
Kally is not a medical device, not a diagnostic tool, not a treatment, and not a substitute for professional advice. Nothing in the App is a medical opinion. Do not use it to diagnose, treat, cure or prevent any condition, to make a decision about medication, or in place of consulting a clinician.
6.2 Estimates, Not Measurements
Every figure Kally produces is an estimate, derived from a photograph and the details you give us rather than from a laboratory measurement. That is a limit of the method, and it is worth understanding: a photograph cannot show how much oil a pan held, how much salt went into a sauce, or what is underneath what — and hydration, sleep and the time of day all move a reading that food alone does not explain.
Kally is built to make those limits visible rather than hide them. A day it has only seen part of is marked provisional instead of being given a confident number, and any figure can be corrected by you. The readings are designed to show you patterns across days and weeks, which is where they are useful, rather than to be precise about a single meal.
We do not warrant that any reading, estimate, target or suggestion is accurate, complete or suitable for you, and you accept that acting on them is your own decision. Where a number matters medically, confirm it against a source intended for that purpose.
6.3 When to Speak to a Clinician First
Speak to a qualified clinician before relying on any target or reading in this App if you have or suspect an eating disorder or disordered eating; if you have a kidney, heart, liver, thyroid or blood-pressure condition; if you are on a sodium-restricted, potassium-restricted or other medically prescribed diet; if you are pregnant or breastfeeding; or if you are under 18. If you are having a medical emergency, contact your local emergency service — not this App.
6.4 Assumption of Risk
You use Kally voluntarily, for general wellness, and you accept the risk of doing so. Any change you make to your diet, sodium or fluid intake on the strength of something this App showed you is your decision. If a reading conflicts with advice from a clinician, follow the clinician.
7. User Responsibilities
You agree not to:
Upload photographs of anyone who has not agreed to it, or content that is unlawful, or content that is not what the scanner asks for.
Reverse engineer, decompile or disassemble the App, or try to extract our API keys, prompts or models.
Access another user's data, probe or test our systems, or work around rate limits, quotas or the paywall.
Use the service to build a competing product, or to generate training data for a model.
Resell, sublicense or redistribute the service, or share your account.
Automate access — scripts, scrapers, emulators or bulk requests — without our written permission.
Use the App in a way that breaks the law where you are, or that infringes anyone's rights.
We may suspend or close an account that breaches this section, and we may do so without notice where the breach is serious or ongoing.
8. Content and Intellectual Property
8.1 Our Content
The App, its design, its interface, its scoring logic and everything in it other than your own content belong to Kally and are protected by intellectual property law. These Terms grant you a personal, limited, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control — nothing more. Nothing is assigned to you, and all rights not expressly granted are reserved.
8.2 Your Content
The photographs and logs you create remain yours. You grant us a worldwide, non-exclusive, royalty-free licence to host, store, resize, transmit and process them for the sole purpose of running the service for you — analysing a scan, showing you your history, computing your trends. That licence exists only so that the App can work, it is not transferable beyond the providers listed in our Privacy Policy, and it ends when you delete the content or your account.
We do not use your photographs or logs to train models, we do not use them in marketing, and we do not publish them. You confirm you have the right to upload what you upload, and that any person appearing in a photo you submit has agreed to it.
8.3 Feedback
If you send us a suggestion, we may use it freely and without obligation to you. That is the only thing in this section that survives your account.
9. Privacy
How we handle your data — including your photographs and health information — is covered separately in our Privacy Policy, which forms part of these Terms.
10. Disclaimers
10.1 Service Availability
We aim to keep the service running but do not guarantee it. Features may change, be added, or be withdrawn, and scan analysis depends on third-party services that can fail, change their terms, or rate-limit us. We may impose reasonable usage limits to keep the service affordable and available to everyone. Where we permanently withdraw a material feature you have paid for, you may cancel and seek a pro-rata refund through the platform, and we will support that request.
10.2 No Warranty
To the fullest extent the law allows, the service is provided "as is" and "as available", without warranties of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the service will be uninterrupted, error-free, secure against every attack, or that any result it produces is accurate or suitable for you.
Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you. If you are a consumer, your statutory rights are unaffected by anything in these Terms.
11. Limitation of Liability
To the fullest extent the law allows, we are not liable for any indirect, incidental, special, consequential, exemplary or punitive loss; for lost profits, lost data, or the cost of substitute services; or for any health outcome, dietary decision or bodily consequence arising from your use of the service or your reliance on anything it produces.
Where liability cannot be excluded, our total aggregate liability to you for all claims is limited to the greater of the amount you actually paid us in the twelve months before the event giving rise to the claim, or fifty US dollars ($50). These limits apply however the claim arises — contract, negligence, statute or otherwise — and even if we were told the loss was possible.
Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be limited or excluded where you live.
12. Indemnification
You agree to indemnify and hold Kally harmless from any claim, demand, loss or reasonable legal cost brought by a third party and arising out of content you upload, your breach of these Terms, your misuse of the service, or your violation of any law or of anyone else's rights. We will tell you promptly of any such claim and will not settle it in a way that imposes an obligation on you without your consent.
13. Termination
13.1 Termination by You
You can close your account at any time from Settings → Privacy & Data. Doing so deletes your data permanently and does not cancel a paid subscription — cancel that in your store account separately, or you will keep being charged.
13.2 Termination by Us
We may suspend or close your account if you materially breach these Terms, if we are required to by law, or if we discontinue the service. If we discontinue the service entirely, we will give you reasonable notice and a chance to export your data.
13.3 Effect of Termination
On termination your right to use the App ceases immediately. Sections 8 through 15 survive termination.
14. Dispute Resolution
14.1 Talk to Us First, Wherever You Are
Before starting any formal proceedings, email support@kally.app describing the problem and what you want. Most things are fixable, and both sides agree to try in good faith for 60 days.
14.2 Arbitration — United States Only
If we cannot resolve it, you and we agree that any dispute arising out of or relating to these Terms or the service will be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under the AAA Consumer Arbitration Rules, rather than in court, and that the Federal Arbitration Act governs this section. The arbitrator decides all issues except the enforceability of the class waiver below, which is for a court to decide.
14.3 Class Action and Jury Waiver
Claims may be brought only in your individual capacity, not as a plaintiff or class member in any class, consolidated or representative proceeding, and the arbitrator may not consolidate claims or preside over a class. If this waiver is found unenforceable as to a particular claim, that claim alone goes to court and the rest of this section still stands. You and we each waive the right to a jury trial for anything covered by this section.
14.4 Small Claims, Time Limit, and Your Right to Opt Out
Either of us may still bring an individual claim in small claims court, and either of us may seek an injunction to stop misuse of intellectual property. Any claim must be brought within one year of when it arose, or it is permanently barred, except where a longer period cannot lawfully be shortened.
You can reject this arbitration agreement entirely by emailing support@kally.app with the subject "Arbitration Opt-Out" and your account email within 30 days of first accepting these Terms. Opting out costs you nothing else in this agreement, and we will not treat you differently for it.
14.5 UK, EU and Other Consumers — Arbitration Does Not Apply
If you are a consumer in the UK, the EU, or anywhere a pre-dispute arbitration clause does not bind consumers, sections 14.2 to 14.4 do not apply to you. You may bring proceedings in the courts of your own country, and you keep every right your local consumer law gives you. EU consumers may also use the European Commission's online dispute resolution platform.
15. Apple App Store Terms
These provisions apply if you obtained Kally from the Apple App Store, and are required by Apple:
This agreement is between you and Kally only, not with Apple. Apple is not responsible for the App or its content.
Your licence to use the App is limited to a non-transferable licence to use it on any Apple-branded product you own or control, as permitted by the Usage Rules in Apple's Media Services Terms.
Apple has no obligation whatsoever to provide any maintenance or support for the App. Support is ours: support@kally.app.
If the App fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation of any kind, and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are ours.
We, not Apple, are responsible for addressing any claim by you or a third party relating to the App, including product liability claims, any claim that the App fails to conform to a legal or regulatory requirement, and claims arising under consumer protection, privacy or similar legislation.
We, not Apple, are responsible for the investigation, defence, settlement and discharge of any third-party claim that the App infringes that party's intellectual property rights.
You represent that you are not located in a country subject to a US Government embargo or designated as a "terrorist supporting" country, and that you are not on any US Government list of prohibited or restricted parties.
You must comply with any applicable third-party terms of agreement when using the App.
Apple and its subsidiaries are third-party beneficiaries of these Terms and, on your acceptance, have the right to enforce them against you.
16. Changes to These Terms
We may update these Terms. Material changes will be shown in the App before they take effect, and continuing to use Kally after that means you accept them. If you do not, stop using the App and close your account. We will not apply a change retroactively to a dispute that has already arisen. The effective date at the foot of this page always tells you which version you are reading.
17. Governing Law
These Terms are governed by the laws of England and Wales, whose courts have non-exclusive jurisdiction, subject to section 14. If you are a consumer, you keep the protections and the courts of your own country.
18. General
Severability. If any provision is held unenforceable, it is modified to the minimum extent necessary or severed, and the rest remains in force.
No waiver. Not enforcing something once does not waive the right to enforce it later.
Assignment. You may not assign these Terms. We may assign them to a successor of the App, on notice to you.
Force majeure. Neither side is liable for a failure caused by something genuinely beyond its reasonable control.
Entire agreement. These Terms and the Privacy Policy are the whole agreement between us about Kally and replace anything said before. Marketing copy is not a warranty.
Notices. We will contact you at the email on your account or in the App; you contact us at support@kally.app. You agree to receive communications electronically.
19. Contact

20. Acknowledgment
By using the App, you acknowledge that you have read and understood these Terms of Service and agree to be bound by them.
