These are the companies that store or handle data for A Stronger Climber, what each one does, and where they are. If you are in Rehab mode, some of them handle health data — those are marked.
Each of these is a processor: they handle data on our instructions and are not allowed to use it for their own purposes.
Runs the app and stores nearly everything in it. Your database records are held in Cloudflare's EU jurisdiction, and photos you send in chat are stored in an EU bucket.
Handles health data: yes — injuries, pain scores and rehab progress are stored here.
Provides the AI (Claude) that writes your session feedback, weekly summaries and rehab guidance. To produce that text, the relevant parts of your training and injury history are sent to Anthropic.
Handles health data: yes, in Rehab mode — injury type, pain scores and recovery stage are included so the advice accounts for them.
Hosts the web pages themselves — the dashboard and the logging tools you open in a browser. The pages are served from here; your training records are not stored here.
Handles health data: no.
Sends your sign-in codes. When you enter your email address to log in, Resend receives that address and the six-digit code so it can deliver the message. It receives nothing else.
Handles health data: no.
Deliver notifications to your phone, and only if you have turned them on. They receive the address your device gave us and the text of the notification itself. When your coach messages you, the first part of that message is the notification — so it passes through the push service and can appear on your lock screen.
Handles health data: possibly — not because we send health records, but because a coach writing to you about an injury puts those words in the message, and the message preview is the notification. If that matters to you, turn notifications off; nothing else changes.
Almost nothing. The app's code, fonts and charting library are all served from our own domain, so simply opening the dashboard contacts nobody but us. The one exception:
Two things are shared because you choose to share them, not because we send them anywhere:
Booking, the questionnaire before a consultation and the patient record kept by the clinic use other suppliers — they are listed in the clinic's policy at klatreskader.dk/privatlivspolitik (in Danish).
If you want a copy of everything we hold about you, or you want your account deleted, ask your coach or write to dennis@klatreskader.dk. Your patient record — injury and rehab records and messages with your physiotherapist — is kept for at least five years after the latest entry, as the law requires. You can stop injury tracking at any time from the menu; nothing new is recorded from then on.
