2. Medical Disclaimer
TreadLeft is not a medical device and does not provide medical advice.
The "Injury Prevention" alerts and shoe wear calculations are estimates based on general manufacturer data. They do not guarantee protection against injury. Always consult a physician or physiotherapist regarding running injuries. You use this application and its recommendations at your own risk.
3. Affiliate Disclosure
TreadLeft participates in affiliate marketing programs, including but not limited to Amazon Associates and Awin. This means we may earn a commission on purchases made through links in our app or emails, at no extra cost to you.
These commissions help support the maintenance of the app. We prioritize finding the best price for your specific shoe model regardless of the retailer.
4. Third-Party Services (Strava)
TreadLeft uses the Strava API to retrieve your activity data. We are not affiliated with, endorsed by, or sponsored by Strava, Inc.
By connecting your Strava account, you grant us permission to read your gear and activity data solely for the purpose of calculating shoe mileage. We do not write data to your feed or modify your Strava history.
