Frequently asked questions

Is my data safe?

Yes. All conversions happen entirely in your browser. Your files never leave your device.

Can I cancel anytime?

Absolutely. Cancel your Pro subscription at any time from your account settings. No questions asked.

What formats are supported?

FIT, TCX, GPX, and CSV. Convert between any supported pair in seconds.

Do I need an account for free conversion?

Your first conversion is free without an account. Sign up free for unlimited individual conversions — an account is only needed after that or for Pro features.
