Collect less, and keep the tools usable
Core settings, diagnostics, supplier filters, search, and calculators do not require an account.
Calculator and filter data
Calculator inputs and filter choices stay on your device. Shareable settings may appear in the page URL, so do not enter confidential customer or production information into a URL you plan to share.
Analytics
DyeSubSource uses a dedicated self-hosted Umami service to measure page views and limited task events such as a completed calculation, an unsuccessful search, or a click to a supplier. The analytics database is separate from other sites. The tracker honors browser Do Not Track, excludes URL query strings and fragments, and does not send calculator values, free-text searches, customer names, artwork, pricing files, or other sensitive production details.
Corrections
A correction report includes only the details you enter and the page you identify. If online submission is unavailable, the form prepares an email or saved copy and clearly tells you that nothing has been sent.
External sites
Source and supplier links open third-party sites whose privacy and commercial terms control there. DyeSubSource does not proxy their checkout or collect payment information.
Policy updates
This page will be updated if DyeSubSource changes what it collects, how long information is retained, or which service providers receive it.
