ActiGoose is a private training app for a household and the people they invite. It is not a commercial service: nobody pays for it, there are no adverts, and your data is never sold or used for anything but running the app for you. This page says what it keeps about you, where it comes from, who else sees it, and what you can do about it.
Who runs it
ActiGoose is run by its administrator, Matthew, who decides how your data is used and is responsible for it. It can only be used by people the administrator has added. For anything about your data, contact matt.jarv@outlook.com.
What it keeps about you
- Your account: your name, your username, your Telegram account (to send you sign-in codes and notifications), and the devices you are signed in on with when you last used them.
- What you tell it about yourself: your training history, injuries, preferences, notes on food, how Goose should talk to you and your comfortable paces. If you choose to, also your weight, height, birth year and sex.
- Training: the sessions you do and plan, with their times, distances, heart rate, calories and, for sessions with GPS, their route. Also your plans, races, goals, rules and places (gyms, routes, where you will be).
- Health: what your watch or ring measures each day, such as sleep, heart rate variability, resting heart rate, readiness, Body Battery, stress, steps, calories, weight and blood pressure, and how you say you feel in your daily check-in, including any niggles or injuries.
- Food: what you log eating and when, with its amounts and nutrition, and the foods you save.
- Goose: your conversations with Goose, the coaching assistant, and what it reads from files and web pages you share with it. The files themselves are not kept: Goose takes the text (and what a picture shows) and the file is discarded.
- Coaching: which coaches you have let in, and the notes and suggestions passed between you.
Where it comes from
- From you, as you use the app.
- Garmin Connect, if you connect it: your activities and daily health. You give ActiGoose your Garmin login, which it keeps encrypted and uses only to fetch your own data. You can make it forget the login at any time under System, Garmin.
- Oura, if you connect it: your sleep, readiness, activity and other daily health data, through Oura's official connection, which you approve on Oura's own site and can withdraw there at any time.
- TrainHeroic: only the export files you upload yourself.
What it is used for
Only to give you the app: your training, your health and readiness, your food, plans that fit your life, and Goose's answers about all of these. Nothing is used for adverts, sold, or shared beyond what this page lists. There are no analytics or tracking services.
Who else sees it
- Coaches you let in see your training, plans, health and readiness, and your food as daily totals only (eaten, burned, protein and carbs), never your meals. They never see your conversations with Goose. You can remove a coach at any time.
- The administrator runs the server, so can technically reach everything stored on it, and looks only to keep the app working or when you ask.
- Anthropic (Claude), which powers Goose: when you write to Goose or log food with it, what you write and the parts of your data Goose needs to answer (your profile, training, health and plans, for example) are sent to Anthropic to produce the reply. Under Anthropic's commercial terms this is not used to train its models.
- Garmin and Oura, which already hold the data they send. ActiGoose sends nothing to Oura. To Garmin it sends only planned workouts for your watch: the coming week's, if you turn that on, and any you send yourself.
- Telegram, which delivers your sign-in codes and notifications, so it carries those messages.
- OpenStreetMap: addresses you look up for your places go to its search service, and maps of your routes are drawn from its map tiles, which your browser fetches directly.
- Open Food Facts: the names and barcodes of foods you search for. No information about you goes with them.
- Web pages you share with Goose (a race's page, for example) are fetched by the server, as any visit would be.
Where it is kept, and how it is protected
Everything is stored on a private server run by the administrator, not with a cloud provider. The connection to it is always encrypted (HTTPS). You sign in with a code sent to your Telegram rather than a password, and your session is a secure cookie that lasts up to 30 days. Logins for other services (such as Garmin's) are kept encrypted. If the administrator keeps backups, they hold the same data and are protected the same way.
Cookies and your device
ActiGoose sets one cookie, to keep you signed in. It also keeps a few things on your device: your choices in the app (such as whether Goose is pinned), a workout in progress so that it survives losing signal, and a copy of the app's files so a workout can open offline. None of this is used to follow you anywhere else.
How long it is kept
For as long as you have an account, so your history stays useful to you. Files shared with Goose are discarded as soon as they are read. When your account is removed, everything linked to it is deleted with it.
Your choices and rights
- See and correct what is held about you, in the app or by asking.
- Take a copy of your data: System, Export gives you all of it as files.
- Disconnect Garmin or Oura, and remove coaches, at any time.
- Have your account and everything in it deleted, by asking the administrator.
- Object to any use of your data, or ask how it is used.
These are your rights under the Swiss Federal Act on Data Protection and, where it applies, the EU General Data Protection Regulation. To use them, contact matt.jarv@outlook.com. If you are unhappy with the answer, you can complain to the Swiss Federal Data Protection and Information Commissioner (FDPIC) or to the data protection authority where you live.
Children
ActiGoose is not meant for anyone under 16.
