Privacy & data use
Plain-language summary of how we handle your data. Short version: it runs the product for you, and we only train on it if you opt in, de-identified.
What we hold
Your account details, training data (activities and the metrics we compute), wellness data (HRV, resting HR, sleep, weight, and how you feel), planning data, and coaching relationships. We treat HRV, resting HR, sleep and weight as sensitive health data.
How we use it
First, to run the product for you: your analysis, readiness and recommendations, synced across devices. Second, to improve our models, but only with your explicit opt-in and only in de-identified form. We never sell your data and run no ad trackers.
Model training
When you turn on "Use my data to improve QuikShift," data entering a training set is stripped of direct identifiers and precise GPS first. Training learns population and personalized patterns, not your individual records. It is off by default and revocable, and turning it off excludes your data from future training.
Where the models run
In development our models run on QuikShift-controlled hardware, not third-party model APIs. If that ever changes, this policy is updated before any data leaves our control.
Your rights
Access and export your data, delete your account, and withdraw training consent any time in Settings. Coach access is limited to the permissions you grant and is revocable.
Security
Passwords are stored only as PBKDF2-SHA256 hashes; sessions are random tokens. Your data is tied to your account.
This summary is a working draft pending legal review. Manage your training-data consent any time in Settings.
