Checked 2026-09-03. Every line links the page we found it on. A cross means we found nothing at the addresses we checked, not that the vendor has no such document. A transparency score, not a product rating.

We do not issue badges: a badge is the first step towards a paid placement, and there is none here. The SVG is a document with the date in it, for your own files.

The label is the whole measurement in one object: every criterion with its weight, the band, and the date. Public transparency score, not a product or security rating.

Every line in it links the page we found the result on, or lists the addresses we checked. A cross means we found nothing there, not that Proton Drive has no such document.
