Provider and scope
The provider is Yusuf Senel, Log-System Development, Von-Hünefeld-Str. 8, 40764 Langenfeld, Germany. Contact details are in the Legal notice.
These terms apply to the web app at kostenlos-abnehmen.de. How we handle your data is explained in the Privacy policy. It is not part of these terms.
What the app offers
You choose a goal, a way and how much you record. The app gives you a plan, timer and entries for this. This works without an account, and the data then stays on your device. With an account you also get the photo estimate and optional sync.
Use is free of charge. A contract for an account is formed when you sign in.
No medical advice
The app does not replace medical advice, diagnosis or treatment. It is not intended to detect, monitor or treat diseases. On request it shows a target range for a calorie deficit you choose yourself. This is orientation, not a recommendation. It promises no results.
Talk to your doctor before changing your diet significantly if you have existing conditions or take medication. Stop and get help if fasting, tracking or your eating is making you feel bad.
Who the app is not meant for, or only in part
- Under 18: The app is for adults only. There is no plan for anyone under 18.
- Eating disorder, including in the past: Counting calories and fasting can make an eating disorder worse. We then offer no plan for any goal. Help is available from the advice line of the German Federal Institute of Public Health on +49 221 892031 and at essstoerungen.bioeg.de.
- Pregnancy and breastfeeding: The goal “lose weight” is not available. For the other goals, the protein interval and intermittent fasting are hidden. That doesn’t mean “track calories” is right for you.
- Diabetes or kidney disease: The protein interval and intermittent fasting are hidden. That doesn’t mean “track calories” is right for you. Check your plans with a doctor first.
- Underweight (BMI below 18.5): The goal “lose weight” is not available.
The app checks this only through your own answers. So answer the safety questions honestly and update them if anything changes.
Estimates and product data
All figures in the app are guide values, with no warranty that they are correct:
- Photo estimate: An AI model estimates from a photo. Amounts, ingredients and protein in particular often cannot be recognised reliably. Check the result before you log it.
- Daily energy need: The formula gives a range of ±10%. Your real need may also lie outside it.
- Nutrition photo: Text recognition makes mistakes. It only pre-fills a form for you to check.
- Product data: It comes from Open Food Facts and from other users, may be wrong or out of date and is not intended for medical purposes. If in doubt, the package counts. This matters most for allergies and intolerances.
These values are no basis for medical decisions, such as dosing insulin.
Availability and changes to the app
The app is free. You have no claim to it or individual functions being available at all times. The photo estimate is limited to 20 photos a day and may be at capacity.
We may develop the app, change functions, adjust limits or end the service. If we end sync or the app, we will say so with reasonable notice so that you can export your data. Back up important data yourself: what exists only in your browser is lost if you clear browser data or change device.
Account and deletion
For an account you need an email address that belongs to you, or a Google account. An account is for you personally. Protect access to your mailbox and your devices.
You can delete your account at any time without notice in the settings. We can terminate the contract with 30 days' notice. For good cause, such as serious or repeated abuse, we can also block or terminate an account immediately. We will then tell you the reason as far as this is allowed, and you can export your data first unless there is a reason against it.
Permitted use
The app is meant for your personal use. You may not:
- bypass limits, safety questions or protective measures
- query the app or its interfaces automatically or overload them; for product data there is the download
- send photos showing anything other than food, in particular other people or other people's data
- post illegal content or infringe the rights of others
Contributions to the product database
You can save products for everyone. This is optional and works without an account.
- Enter only details printed on the package. Do not copy from other databases.
- Do not enter personal data, links or advertising in the name or brand.
- Contributions are public. Until a second device enters the same values, they count as unchecked.
To the extent that rights exist in your contribution, you place it under the Open Database License 1.0 and individual contents under the Database Contents License 1.0. Anyone may then use the data under these licences, even if you delete your account or we remove the contribution. Rights in copies already published cannot be taken back.
We may check, correct, mark as disputed, replace with data from Open Food Facts or remove contributions, for example if they are wrong or break these rules. There is no claim to publication.
Data from Open Food Facts
A large part of the product data comes from Open Food Facts and is available under the Open Database License. Individual contents are under the Database Contents License. The whole database is available free of charge on the Data sources page.
Data from the Max Rubner-Institut
General foods come from the German Nutrient Database of the Max Rubner-Institut and are licensed under CC BY 4.0. We only use part of the data. The institute doesn't endorse this app.
Reporting wrong and illegal content
Report wrong values directly on the product with “Values are wrong”. After several reports, the app marks the product as disputed.
Please report illegal content, such as insulting product names or personal data, by email to [email protected]. Name the barcode or product, explain why the content is illegal and give your name and email address (Art. 16 of Regulation (EU) 2022/2065). We confirm receipt, review the report and tell you our decision.
Liability
We are liable without limit for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act and where we have given a guarantee.
For slight negligence we are otherwise liable only if we breach an essential contractual duty, meaning a duty whose fulfilment makes use possible in the first place and on which you may rely. Liability is then limited to the foreseeable, typical damage.
Otherwise our liability is excluded. This also applies to our legal representatives and vicarious agents.
Rights in the app
The texts, design and software of the app belong to us or our licensors. You may use them within these terms. Your own data remains yours.
Changes to these terms
We may change these terms, for example when new functions are added or the law changes. We will tell you in advance about changes that put you in a worse position. For existing accounts they apply only once you agree. Your silence does not count as agreement. If you do not agree, the old version continues to apply, and we may terminate the account as described above.
Dispute resolution and applicable law
We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.
German law applies. Mandatory consumer protection rules of the country where you have your habitual residence remain unaffected.
These terms exist in German and English. If the versions differ, the German version applies.
