What comes down, what never goes up

DownloadTime turns megabytes into minutes inside your tab. The file sizes and speeds you work with are computed locally: no form, no endpoint, no application server waiting for your numbers. Cut the network after loading and every calculation still comes out.

Memory: none

The tool writes no localStorage and no first-party cookies. Reloading returns the fields to their defaults — the forgetting is total and deliberate.

Who does see traffic

• Cloudflare delivers the files and logs routine server metadata — IP, agent, time, path — to run the site and fend off abuse.
• Google AdSense may manage its own cookies for ad delivery and measurement; personalization is controlled in Google’s ad settings or at aboutads.info, with zero effect on the calculator.
• A counter tick — a single per-visit event carrying the page, the referrer, the CDN-estimated country and duration — cookieless, identifier-free.

Scope and contact

A general-audience utility with no sign-up and no collection: there is nothing here to ask of anyone, at any age. Changes to this policy replace this page. Privacy: hello@tolerence.net, or the contact page.
