Simstim
Terms of Use
Draft. Not yet reviewed by a lawyer. Parts still to be completed are highlighted: [to fill in: …].
Simstim is not a medical device. Estimates and targets are recommendations, not a diagnosis or a prescription. They do not replace a doctor, dietitian or coach. Details - section 4.
1. What these terms cover
This is an agreement between you and the operator of Simstim - [to fill in: name or company, address, country] (“we”). It covers the Simstim apps for Android and iPhone, the simstim.app website and connecting an AI coach (MCP). How we handle data is described in the Privacy Policy, which is part of these terms. By signing up you accept these terms; if you do not agree, do not use the service.
2. Your account
- Sign-up is by invite code. You must be at least 16 years old.
- One account per person. Use your real email: password reset and confirmation links are sent to it.
- You choose your country once at sign-up - data rules depend on it; later it can be changed through support.
- Keep your password secret. We will never ask for it by email or chat. If you notice someone else signing in, change your password and revoke sessions in the app.
3. What Simstim does
Simstim is a personal log: food with estimated calories and macros, workouts from your phone and connected services, weight and body composition, sleep and heart rate, a food budget, readiness and progress, friends and a feed. We keep developing the service: features appear, change and sometimes go away. We try to keep it running at all times but do not promise uninterrupted operation - there are updates and outages of third-party services and networks. The service is provided “as is”.
4. Not medical advice
- Simstim is not a medical device and is not intended to diagnose, treat, prevent or monitor any disease.
- Everything Simstim shows is a recommendation or an estimate: calorie and macro targets, deficit and weight-loss pace, energy from workouts and steps, “readiness”, body composition assessed against norms, Progress insights, AI tips and estimates. They are calculated from general formulas and your data, which can be inaccurate (watches, scales, photos), and can be wrong.
- It is not a substitute for a doctor, dietitian, coach or other professional. Talk to them before changing your diet or training, especially significantly. You must do so if you are pregnant or breastfeeding, have a chronic condition (heart, blood pressure, diabetes, kidneys and others), have or have had an eating disorder, take medication, are recovering from an injury or surgery, or are under 18.
- Safety limits (the lower bound of the food budget, the maximum deficit) are a safeguard, not a guarantee that a target suits you.
- If you feel chest pain, severe shortness of breath or dizziness during exercise, stop and get help. In an emergency call your local emergency number (112 in the EU, 911 in the US). Do not delay seeing a doctor because of something the app showed.
- You make the decisions about your health; to the extent the law allows, we are not responsible for the consequences of decisions based solely on Simstim's estimates.
5. AI estimates
- Calories from photos, parsing strength workouts and reading scale reports are done by AI. They are approximate: check the result and edit it before saving.
- Only send your own content: do not upload photos of other people without their consent, documents, or anything unrelated to food and training.
- What goes to AI providers and what does not - in the Privacy Policy.
6. Your data and content
- Your records, photos and notes are yours. You give us the right to store, process and display them - to you and to people you give access to - only to run the service. This right ends when you delete the data or your account (subject to the backup and log provisions in the policy).
- You are responsible for what you upload: you must have the rights to photos and texts.
- A dish you send to a friend stays with them as a snapshot, even if you later change or delete yours.
- You can download all your data at any time: Profile → Privacy → Download all data.
7. Rules for everyone
You may not:
- use Simstim against the law or the rights of others; post illegal or abusive content or other people's personal data;
- harass, intimidate or deceive other people - including through friends, the feed, shared dishes and Friends nearby;
- try to access other people's data, bypass security, guess passwords and codes, overload the server, or reverse-engineer it outside permitted means;
- collect data automatically - except through your own coach via MCP and access we grant;
- resell access to the service or impersonate someone else.
8. Third-party services
- Strava, Hevy, Zwift, TrainerDay, Health Connect, Apple Health and your Claude are separate services with their own terms. When you connect them, you decide what to import and send, and you follow their rules.
- We are not responsible for how these services work or what they do with data you have given them.
- Zwift is connected with your Zwift login and password through an unofficial sign-in method: Zwift may restrict this and access may stop working.
- When you connect Strava, you decide whether to send workouts there: “Send workouts to Strava” is off by default and the app asks when you connect. If you turn it on, workouts from Health Connect / Apple Health that are not in Strava will be uploaded there; you can turn it off at any time in the Strava connection settings.
9. Subscriptions
Some features may be available only with a subscription. Subscriptions are currently granted manually and there are no in-app payments. When payments arrive, this section will set out prices, payment, renewal, cancellation and refunds - [to fill in: plans, payment via Google Play / App Store, refunds, the EU 14-day withdrawal right].
10. Deletion and suspension
- You can delete your account at any time: Profile → Privacy → Delete account and data. How and when data is erased is in the policy.
- We may restrict or close an account that breaks these terms or the law, or threatens the safety of others or the service. Unless the law forbids it or it would hinder an investigation, we will tell you why and let you download your data.
- If we shut the service down entirely, we will give notice [to fill in: how many days] in advance and let you download your data.
11. Liability
- We are liable for intent and gross negligence, for injury to life or health caused by us, and in other cases where liability cannot be limited by law.
- Otherwise, to the extent the law allows, we are not liable for indirect loss, lost profits, data loss caused by third-party outages, or decisions based solely on Simstim's estimates (section 4). [to fill in / lawyer: liability cap]
- If you are a consumer, these terms do not take away rights the law of your country gives you.
12. Governing law and disputes
Governing law: [to fill in: country], without prejudice to the mandatory consumer protection rules of the country where you live. Disputes: [to fill in: court or procedure]. Please write to us first - most issues are solved by email.
13. Changes
These terms have a version (at the top). We will tell you about material changes in the app in advance [to fill in: how many days]. If you do not agree with the new terms, you can download your data and delete your account; by continuing to use the service you accept the new version.
