Terms of Use

Vimly. Last updated November 9, 2026.

Agreement

These Terms of Use are an agreement between you and Jason Luo ("we", "us"), the developer of Vimly. They cover the Vimly app, its Watch app, widgets and shortcuts, and website. By tapping Agree, Continue or Start in the app, or by using Vimly, you agree to them. If you do not agree, do not use the app. The Privacy Policy explains how we handle personal data. You acknowledge it, but you do not agree to it as a contract: it is information for you, not part of these terms.

Who can use Vimly

Vimly is a calorie, protein and lifting tracker for personal use by people aged 13 or older. If you are under 18 (or under the age of majority where you live), ask a parent or guardian to read these terms with you before you use Vimly. Some places require a parent's consent for people under 16, and where that applies, you may use Vimly only with that consent. You must not use Vimly where the law does not allow it.

Not medical advice

Vimly gives general estimates, not medical advice. Talk to a doctor before changing how you eat or train, especially if you are under 18, pregnant, have a medical condition, or have had an eating disorder. Targets are not designed for pregnancy or breastfeeding.

Vimly is not a medical device and is not meant to diagnose, treat, cure or prevent any disease. It is not a substitute for a doctor, registered dietitian or qualified coach, and it is not for medical emergencies. Calorie, macro and protein numbers, including any AI estimate, are approximations and can be wrong. Never ignore professional advice, or delay getting it, because of something in Vimly. Stop and seek medical advice if you feel unwell.

Vimly's safety limits: daily calories never go below the higher of your estimated resting burn and 1,500 calories (men) or 1,200 calories (women); weight loss is capped at 1% of body weight a week; extra calories for building are 5 to 10% (5% under 18); fat-loss goals are not offered under 18 or when BMI is under 18.5, and a fat-loss plan switches to maintenance if either applies later; and setup is not available under 13: once a birth date under 13 is entered, setup stays closed on that phone. These are general rules of thumb, not a promise that a target is right or safe for you.

Burned calories for activities and workouts come from standard formulas or from Apple Health, and net calories are worked out from them; both can be far off. The workout plan maker builds plans from simple rules and a built-in exercise list, not from a coach who knows you, your injuries or your health. Meal ideas come from a built-in list with typical nutrition numbers. They do not know about your allergies, intolerances, medical conditions, medicines or dietary needs, so check every ingredient yourself and skip anything that is not right for you.

If food, weight or calorie counting is causing distress, or leads to skipping meals, bingeing, purging or over-exercising, stop using the calorie features and talk to a doctor. US: call or text 988 if you are in crisis, or contact the National Alliance for Eating Disorders (allianceforeatingdisorders.com). UK: Beat (beateatingdisorders.org.uk). Elsewhere: findahelpline.com or your local emergency number.

Exercise and lifting: your risk

Lifting weights and other exercise carry a real risk of injury, including strains, fractures, heart problems and, rarely, death. Get a doctor's clearance before starting, learn proper form (ideally from a qualified coach), use a spotter and safe equipment, warm up, and stop right away if you feel pain, dizziness, chest pain or shortness of breath. Workout plans and suggestions, rest timers and records in Vimly are tools, not coaching. You choose what you lift and how, and you take on the risks of doing it. To the extent the law allows, you agree that you use Vimly's lifting and nutrition features voluntarily and at your own risk.

Your data and your content

What you log is yours. It stays on your phone unless you sign in to back it up (see the Privacy Policy). The backup is a convenience, not a guarantee: it can fail, fall behind or be lost, and it never includes meal photos or Apple Health data. You are responsible for exporting anything you want to keep, especially before you delete data, the app or your account. We cannot recover data that is not in your backup. When you send a meal for an estimate, you let us process it, and pass it to our service providers, only to return the estimate. Send only food, and nothing you do not have the right to share. If you send us ideas or feedback, we may use them freely without paying you.

Your account (optional)

An account is optional. Vimly works fully on your phone without one; signing in with Apple only adds the optional backup of your log. If you create an account, you do so with Sign in with Apple. Keep your Apple Account secure: anyone who can sign in to it can see and change your backup. The account is for you alone; do not share it or use someone else's. You can delete it at any time in Settings > Account > Delete account. We may suspend or delete an account that breaks these terms, harms the service or other people, or has to be removed by law. If we stop offering accounts or backups, we will tell you in the app first and give you time to export your log. Backups have size limits, and syncing needs an internet connection.

Your license to use Vimly

We give you a personal, limited, non-exclusive, non-transferable, revocable license to download and use Vimly for your own non-commercial use on Apple-branded devices that you own or control, as allowed by the Usage Rules in Apple's Media Services Terms and Conditions (including Family Sharing where it applies). We and our licensors keep all other rights. Open-source parts of the app are covered by their own licenses, listed under Settings > About.

Acceptable use

You agree not to:

• copy, modify, sell, rent, sublicense or redistribute the app;
• reverse engineer, decompile or try to get its source code, except where the law allows it despite this;
• get around its safety limits, security, usage caps or any technical protection;
• overload, scrape or misuse the estimation service, or send it anything unlawful, harmful or not about food;
• use it to break the law, to harm yourself or anyone else, or for anyone under 13;
• use Vimly's name, logo or look to suggest that we endorse you.

Ownership

Vimly, its name, icon, design, text, code and other content belong to Jason Luo or our licensors and are protected by copyright, trademark and other laws. These terms give you no rights to them except the license above.

Outside services

Vimly works with services we do not control, such as Apple's App Store, iOS, Siri, Apple Watch, Apple Health, Sign in with Apple, and TestFlight, our hosting provider (Supabase), and OpenRouter and the AI model provider that read meals for estimates, and Open Food Facts, a public food database whose data comes from contributors and can be wrong. Their own terms and privacy policies apply to them, and we are not responsible for them. You must also follow any third-party terms that apply when you use Vimly, such as your mobile data plan. Apple's Media Services Terms: https://www.apple.com/legal/internet-services/itunes/

Your device, internet and data charges

Logging, your plan and your history work without an internet connection. Things that need one (such as backing up your log, meal estimates, food lookups, emailing support or opening the website) may not work without it, and your mobile carrier's or internet provider's charges, including roaming, are yours. Keeping your iPhone charged, updated and secure is up to you. Do not use Vimly on a jailbroken device: removing iOS's protections can expose your data and stop the app working properly, and we are not responsible for what happens if you do.

Price

Vimly is free in this version, including the optional backup, and has nothing for sale. If paid features are added later, the price and terms will be shown before you pay, payment will go through Apple, and these terms will be updated first.

Changes, updates and availability

We may update, change, limit or stop any part of Vimly, and you may need an update to keep using it. We will tell you about changes that significantly affect your use, and we will not remove core features without a valid reason. We do not promise that the app will work on every device or iOS version.

No warranty

VIMLY IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE FULLEST EXTENT THE LAW ALLOWS, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, QUIET ENJOYMENT AND NON-INFRINGEMENT. WE DO NOT PROMISE THAT VIMLY'S NUMBERS ARE ACCURATE OR RIGHT FOR YOU, THAT IT WILL MEET YOUR GOALS, THAT IT WILL BE UNINTERRUPTED, SECURE OR ERROR-FREE, OR THAT YOUR DATA WILL NOT BE LOST. Some places do not allow these exclusions, so some may not apply to you.

Limitation of liability

TO THE FULLEST EXTENT THE LAW ALLOWS, WE ARE NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, PROFITS OR GOODWILL, ARISING OUT OF OR RELATED TO VIMLY, EVEN IF WE WERE TOLD THEY WERE POSSIBLE. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATED TO VIMLY IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID US FOR VIMLY IN THE 12 MONTHS BEFORE THE CLAIM AND 50 US DOLLARS. These limits apply under every legal theory and even if a remedy fails of its essential purpose.

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud, for intentional or grossly negligent acts, or for anything else that cannot be limited by law.

Consumer rights. If you are a consumer, you may have legal rights that cannot be excluded, such as the Australian Consumer Law consumer guarantees, the New Zealand Consumer Guarantees Act, and the consumer laws of the UK, Canada and US states. Nothing in these terms limits those rights, and the warranty disclaimers and liability limits above apply only so far as those laws allow.

We are not responsible for losses from relying only on food database entries from others, or on numbers you entered yourself. AI estimates are approximations; check anything that matters.

Indemnity

To the extent the law allows, you agree to defend and hold harmless Jason Luo from any claims, losses and costs (including reasonable legal fees) brought by someone else that arise from your misuse of Vimly, your breaking these terms, or your breaking the law or someone else's rights. This does not cover claims caused by our own negligence, our breaking these terms, or our breaking the law. This section does not apply to consumers in the EEA, the UK or Switzerland. This section does not apply if you are under 18.

Apple App Store terms

If you got Vimly from Apple's App Store, these points also apply, and they control if anything else in these terms conflicts with them as far as Apple is concerned:

• These terms are between you and Jason Luo only, not Apple. We, not Apple, are solely responsible for Vimly and its content.
• Your license is limited to using Vimly on Apple-branded products you own or control, as allowed by the Usage Rules in Apple's Media Services Terms and Conditions, which these terms do not override.
• We alone are responsible for any maintenance and support. Apple has no obligation at all to provide maintenance or support for Vimly.
• If Vimly fails to meet any warranty that applies and has not been effectively disclaimed, you may tell Apple, and Apple will refund the purchase price you paid (if any). To the maximum extent the law allows, Apple has no other warranty obligation for Vimly, and any other claims, losses, liabilities, damages, costs or expenses from a failure to meet a warranty are our responsibility, to the extent they are not disclaimed in these terms.
• We, not Apple, are responsible for addressing any claims by you or any third party relating to Vimly or your possession and use of Vimly, including (i) product liability claims; (ii) any claim that Vimly fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy or similar legislation, including in connection with Vimly's use of the HealthKit framework.
• If anyone claims that Vimly or your having and using it infringes their intellectual property rights, we, not Apple, are solely responsible for investigating, defending, settling and discharging that claim.
• You confirm that you are not located in a country subject to a US Government embargo or designated by the US Government as a “terrorist supporting” country, and that you are not on any US Government list of prohibited or restricted parties.
• Questions, complaints or claims about Vimly go to Jason Luo, Ohio, United States, support@getvimly.com.
• You must follow any third-party terms that apply when using Vimly.
• Apple and Apple's subsidiaries are third-party beneficiaries of these terms. Once you accept them, Apple has the right (and is treated as having accepted the right) to enforce them against you as a third-party beneficiary.

Disputes

Before filing a claim, email support@getvimly.com and give us 60 days to try to resolve it. If we cannot, either of us may bring the claim in court as described under “Governing law”. Nothing in these terms stops you bringing a claim in small claims court or contacting a consumer or data protection authority.

Governing law

These terms are governed by the laws of the State of Ohio, USA, and applicable US federal law, without regard to conflict-of-law rules. Claims go to the state or federal courts in Ohio, unless the law of your state or country lets you bring the claim where you live. If you live outside the US, you also keep the protection of the mandatory consumer laws of the country where you live, and nothing in these terms takes away your statutory rights as a consumer.

Ending these terms

You can stop using Vimly at any time by deleting it. Your license ends automatically if you break these terms, and we may end it or stop offering Vimly at any time. When it ends you must stop using and delete the app, and we may delete your account and backup (after giving you a chance to export, unless the law or a serious breach prevents it). The sections on health, exercise risk, ownership, no warranty, limitation of liability, indemnity, disputes, governing law and the general terms still apply after it ends.

Changes to these terms

We may update these terms for legal, security or product reasons. For any material change we will tell you in the app at least 30 days before it takes effect, unless a legal or security reason requires it sooner. If you keep using Vimly after that date you accept the new terms; if you do not agree, stop using Vimly and delete your account and data at no cost. We change the date below with every update. Earlier versions are available on request.

General

These terms are the whole agreement between you and us about Vimly. If any part is found unenforceable, the rest stays in effect and that part is applied as far as the law allows. If we do not enforce a term right away, we have not given up the right to. You may not transfer these terms; we may transfer them, for example if Vimly is sold. We are not responsible for delays or failures caused by events beyond our reasonable control. You must follow all export and sanctions laws that apply to you. Headings are for convenience only.
