About Jaeyeon
Jaeyeon builds practical mobile tools with a strong bias toward clear workflows, transparent policies, and support pages that real users can actually use. Running Machine reflects that approach by focusing on a simple product promise: faster treadmill logging without removing the user's final review step.

What the product is trying to solve
Running Machine started from a small but familiar post-workout frustration: treadmill runners often take a quick photo of the console, then still have to type the result back into a separate log later.
The goal is not to automate fitness tracking in a vague way. It is to reduce that repetitive step while keeping the runner in control of what gets saved.
How the product is built
The experience is shaped around a review-first workflow. A treadmill photo becomes a draft, the runner checks it, and only then is the workout stored in history.
- Keep the capture-to-save flow easy to understand.
- Explain privacy, support, and deletion pathways in plain language.
- Treat support and legal pages as part of the product, not as afterthoughts.
Support principles
This site exists so users, store reviewers, and future partners can quickly verify how the app works, how data is handled, and how to get help when something goes wrong.
- Publish support and policy pages at stable public URLs.
- Keep release notes readable and specific.
- Document account deletion steps and retention notes clearly.
