Adherence

TermsThe agreement

Last updated 9 August 2026

These terms are an agreement between you and the developer of Adherence. Using the app means you accept them. If you do not, please do not use it.

General wellness, not medical advice

Adherence is a general wellness and educational tool. It is not a medical device, it does not provide medical advice, and it does not diagnose, treat, cure or prevent any disease. Its scores are general information drawn from published dietary research, not personalised clinical guidance. Talk to your doctor or a qualified professional before changing your diet, and never delay professional advice because of something this app showed you. If you have a medical condition, a food allergy or an eating disorder, or you are pregnant or nursing, seek professional advice first.

What the scores are

Every score is an estimate of a weekly pattern, not a measurement of what you ate. A photograph cannot recover grams, so portions are four coarse steps and each score inherits that resolution. A partial week is projected to a full one, and the app says so where it shows the number. If a scoring method is revised in a later version, your score may change without notice. No score is a diagnosis or a nutritional assessment.

The scores are not the published ones

Scores are computed on this device from published dietary research, but each one is this app’s implementation of a rubric rather than the published score itself. Every rubric is adapted to what a photographic log can see: amounts are derived from public United States Department of Agriculture food data, some components are inferred from the dishes you confirm rather than asked of you, and a component your log has not spoken to is left out of the total instead of counted as a zero. Where a component cannot be observed at all it is omitted, and the total is out of less than the published maximum. Each rubric page names its own adaptations and cites the research it comes from. A score shown here may therefore differ from one calculated by the same method from a complete dietary record.

Independence

The researchers, journals and public bodies whose published work these rubrics come from are not involved in this app, have not reviewed it, and do not endorse it. Their names appear to credit the source of a scoring method and for no other reason.

You confirm the dish

Recognising a meal from a photograph is approximate by nature. The app analyses the photo on your device and suggests candidate dishes, and those suggestions can be wrong: it may misidentify a dish, rank the right one low, or recognise nothing at all, and no level of recognition accuracy is promised. That is why the app never decides for you — you choose one of the candidates, or describe the dish yourself, and every score follows from that choice, so its accuracy depends on yours. A dish you describe is scored from the ingredients you name and nothing else.

Eligibility

You must be at least 18, or the age of majority where you live, to use the app. By using it you confirm that you are.

Your licence

You are granted a personal, limited, non-exclusive, non-transferable, revocable licence to use the app on Apple devices you own or control, for your own personal, non-commercial use. You may not copy, modify, reverse-engineer, decompile, resell, sublicense or create derivative works from it, except where the law expressly allows it.

Free trial and purchase

The app is free to download and free to use for seven days. The trial begins when you log your first plate, not when you install the app, so you can take a photo, see what it recognises and read how the scoring works without starting it. Nothing is charged when the trial begins and nothing is charged automatically at any point. When the seven days end, the app asks you to buy it before you can carry on; your log is not deleted and is waiting for you if you do. Adherence is then a one-time purchase: a single payment, not a subscription, with nothing that renews. The price is shown in the app and by Apple before you confirm. Apple processes the payment through your Apple ID and we never see or store your payment details. Refunds are handled by Apple under its App Store terms and we cannot issue them directly. If you reinstall the app or move to a new device, you can restore your purchase at no further charge.

Intellectual property

The app — its name, design, software and the selection and arrangement of its content — belongs to the developer and is protected by intellectual-property law. These terms transfer no ownership to you. The developer claims no ownership of the material the app is built on that is free to everyone, such as public food composition data and published research.

Apple

These terms are between you and the developer only, not Apple. Apple is not responsible for the app or its content and has no obligation to provide support or maintenance for it. Your use is also subject to the Apple Media Services Terms and Conditions, and Apple’s standard End User Licence Agreement applies. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them.

No warranty

The app 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 it will be uninterrupted or error-free, or that its dish recognition or its scores are complete or accurate. Every suggestion and every number it shows is produced by automated computation from a photograph or from what you logged, and may contain errors.

Limitation of liability

To the fullest extent permitted by law, the developer is not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of health, data or profits, arising from your use of or inability to use the app, even if advised of the possibility. Where liability cannot be excluded, it is limited to the amount you paid for the app.

Your data is your responsibility

Your log is stored only on your device, so keeping it is up to you. Deleting the app deletes it, and we hold no copy that could be restored. See the privacy policy for how backups work.

Indemnification

You agree to indemnify and hold the developer harmless from any claims, damages or expenses arising from your misuse of the app or your breach of these terms.

Changes

The app and these terms may be updated, changed or discontinued at any time. A purchase includes any updates released, but does not oblige the developer to release future updates or to keep the app on the App Store. Material changes are reflected by updating the date above, and continuing to use the app means you accept them.

Governing law

These terms are governed by the laws of the developer’s place of residence, without regard to conflict-of-law rules, except where mandatory local consumer-protection law gives you additional rights.

Severability

If any provision of these terms is held invalid or unenforceable, it is limited or removed to the minimum extent necessary and the rest remains in full force.
