Plain-language terms.
What datfit is
A free web tool that suggests a clothing size based on the brand's published size chart and the measurements you enter. Use it as a guide, not a guarantee. Brand sizing varies between styles, fabrics, and production runs — datfit's recommendation is a confident starting point, not a fitting.
No warranty
datfit is provided as-is. If a recommended size doesn't fit, we'll improve the data, but we can't reimburse returns, exchanges, or any related cost.
Acceptable use
Don't try to break the tool, scrape it at scale, or impersonate it. Don't upload other people's content (e.g., copyrighted size charts you don't have rights to share) — your upload stays in your browser anyway, but the principle holds.
Accounts
The optional email/password account is stored locally on your device only (see privacy). You're responsible for the password you choose. If you forget it, there's no recovery — clear site data and create a new one.
Changes
We may update these terms. Significant changes will get a note in the footer of the home page for at least 30 days.
