Privacy Policy
Fitterson is made by Lean Digital Agency LLC (“we”, “us”) – the company responsible for the data described here. Fitterson helps you bring your training and health data together in one place. This policy explains what we collect, why, and the choices you have. It is written in plain language – it is a summary of our practices, not legal advice.
What we collect
- Account details – your name, email address, date of birth, and authentication data needed to sign you in.
- Training data – workouts, exercises, sets, reps, load, and training records, including workout sheets you upload.
- Health data – with your permission, activity, cardio, and VO2Max metrics from Apple Health, plus body-composition and lab results (such as DEXA) you choose to add.
- Your conversations with Ask – the questions you type into Ask and the answers you get back. Your conversation is kept until you clear it or delete your account. Only your most recent conversation is kept.
How we use it
We use your data only to provide the service: to show your trends and progress, to answer your questions about your own data, and to generate personalized, non-medical suggestions to guide your training. We do not sell it, and we do not use it for advertising.
AI features and our AI provider
Three parts of Fitterson use AI. Ask answers questions about your own data. Insights writes automated training suggestions. And when you upload a workout sheet, AI reads the photo and turns it into structured sets and reps for you to check before anything is saved. All of it runs on our servers – never in your browser or on your phone.
We use a single external AI provider. What reaches them: the photo when you upload a workout sheet, the question you type into Ask, the parts of your training data, health metrics, profile, and goals needed to answer it, and the answer that comes back. They process this on our behalf, under contract, to return that result and for nothing else.
Two points we want to be precise about rather than reassuring:
- Your inputs and the answers are not used to train our AI provider’s models. That is a commitment in our contract with them, not a setting that could be flipped.
- They are deleted within 30 days by default – not instantly, and not never stored at all. Our AI provider can hold them longer in narrow situations, such as a legal hold or an investigation into a suspected breach of their usage rules.
Ask is software, not a person. It can be wrong or incomplete, so check anything that matters before you act on it, and never treat it as medical advice.
Apple Health data
Health data read from Apple HealthKit is handled with extra care. We never use it for advertising, never sell it, never share it with data brokers, and never sync it to iCloud. We request the minimum read access needed, and you can revoke it at any time in the iOS Health app.
How it is stored and protected
Your data is stored with our hosting and database provider and transmitted over encrypted connections. Access is enforced at the database layer so that only you can read or write your own records.
Sharing
We do not sell your data and we do not send your health or training data to advertising or analytics services. We share it only with the service providers strictly needed to run Fitterson, and only as described above. Each one works for us under contract, on our instructions, for the job it is there to do and nothing else:
- A hosting and database provider, which stores your account, training, and health data.
- An AI provider, which receives and returns exactly what is described under AI features above.
- A web-analytics provider, on our public marketing pages only – see below. It never runs inside the app and never sees your health or training data.
We describe these providers by what they do rather than by company name, so the list stays accurate if we change one. That applies to our suppliers, not to us: the company responsible for your data is Lean Digital Agency LLC, named at the top of this page.
Analytics on our marketing site
Our public marketing pages – the landing page and this privacy page – use a third-party web-analytics provider to understand how people find and read the site. It sets cookies and collects standard web-analytics data such as the pages visited, the referring site, and coarse device and location information, and it acts as a data processor on our behalf.
This analytics runs only on the public marketing site. It is never present anywhere inside the app, and it collects no health, training, or account data – none of your workouts, Apple Health metrics, or personal records are ever sent to it.
Age
Fitterson is for adults – you need to be 18 or over to use it. We do not knowingly collect data from anyone younger. We ask for your date of birth when you first sign in. If it shows you are under 18 we cannot create an account, and we delete the one you started, along with its data. If you believe someone under 18 has created an account, contact us at the address below and we will delete it.
Your choices
You can delete your account and all of its data at any time, directly in the app – open your Profile and choose Delete account. Deletion is permanent and removes your training records, health data, uploaded sheets, goals, Ask conversations, and profile. You can also request access to or export of your data, and withdraw consent for health-data processing, by contacting us at the address below.
