| Who it's not for | Athletes wanting a human coach or guided plans | Privacy-sensitive users: military, government, executives |
| Privacy | No known public vulnerabilities found in the sources reviewed.⁹ | No confirmed breach of Strava's own servers in sources reviewed, but repeated user-location leaks make privacy configuration essential. |
| Support quality | Community forum only; no formal SLA | No direct evidence in sources reviewed |
| Public sentiment | Endurance athletes on Reddit and the product's own forum describe as a great, deeply capable DIY training-analytics tool that is actively improved.¹ | Users love the tracking depth and community but repeatedly complain about paywalling, aggressive upsells, and price hikes. |
| Biggest gotcha | A user had to publicly ask where to report vulnerabilities; disclosure path unclear⁸ | Free trial can auto-charge a full year; a law firm is investigating complaints |
