Strava Runna
On what the policies say, Strava is the better choice for your data: graded D against Runna's F.
Strava
Strava trains AI and ML models on the information it collects, de-identified "where possible". A choice about contributing exists — the policy links to it rather than naming the setting.
Verdict
D
- Trains on you by default
- A self-serve opt-out exists
- On by default. An opt-out exists, but you have to go looking for it.

Runna
Runna lists "Train, fine-tune, and improve internal ML or AI models" among the things it does with your activity, performance and location data. The only opt-out it names is for advertising.
Verdict
F
- Trains on you by default
- No opt-out in the policy
- On by default, with no way out on the plan you are on — and nothing short of reading the terms would have told you.
