6. Intellectual Property
The TrailMath name, logo, design, and software are owned by TrailMath. Your training data remains yours – see our Privacy Policy for details on data ownership and portability.
7. Race Data Reuse
Race checkpoint tables published at trailmath.run/races - distances, elevation gain and loss, crew access and drop-bag access - are compiled by TrailMath from the official race sources credited on each page. Notwithstanding section 5, you may reuse this data, including in AI training and retrieval, with attribution to trailmath.run and a link to the race page. The figures are provided as-is: verify them against the organiser before relying on them for a race.
8. Subscriptions and Payment
TrailMath has a free plan called Standard and a paid plan called Premium. Standard is not a trial and does not expire.
- Standard includes the training templates, setting up a plan for one goal race, session logging, your full training history, Strava and Garmin sync, rule-based weekly adjustments, a race-day plan, your whole season's phases and weekly volume, and the sessions of the next four weeks for the first four weeks of your plan and of the next two weeks after that
- Premium adds the TrailMath Assistant, including automated plan adjustments that you approve, an automated analysis of every session you log, schedule adaptation, training for more than one goal race in a season, and every session of your season through to race day
- Premium costs 12 EUR per month or 99 EUR per year. The exact amount charged is shown before you confirm, and may differ in your local currency
- A one-off 14-day Premium trial starts when your training plan is generated. It needs no payment details and does not turn into a paid subscription
- Subscriptions renew automatically at the same price until you cancel
- Cancel where you subscribed: in your Apple or Google account settings for a purchase made through an app store, or from Subscription in your TrailMath account settings otherwise
- Cancelling stops the next renewal. Premium stays open until the end of the period you have already paid for
- If we change the price of a running subscription, we will tell you in advance and you can cancel before it takes effect
- Ending Premium deletes nothing. Everything you have logged stays yours, and you keep everything Standard includes
- Features may change, be added, or be removed - we will not remove a material part of the paid plan without notice
Consumers in the European Union. You have 14 days to withdraw from a distance contract without giving a reason. If you asked us to start the service straight away, you may still withdraw within those 14 days and you pay only for the part of the period already supplied. Write to support@trailmath.run to withdraw. Purchases made through the App Store or Google Play are billed by Apple or Google, and their own refund process applies in addition to this right.

To the fullest extent permitted by law, TrailMath shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Service, including but not limited to injuries sustained during training.
