Your files never leave your device.
Analyser reads and analyses every file entirely in your browser. There is no upload and no server that receives it - the name, contents and bytes of anything you drop stay with you, and are gone the moment you close the tab.
What the counters keep.
Two anonymous, aggregate counters and an optional game leaderboard, all shown on the stats page. None of them holds your files or your IP address.
- Files analysed
- Analysing a file sends only its lowercased extension - say
jpgorsldprt- to a tally. Never the name, size or contents. Unrecognised types are counted too, as a private wish-list of what to add next; the stats page shows them only as one combined total. - Visitors
- A count of visits, with no accounts and no cookies. So that one person counts once rather than on every page load, the server keeps a one-way hash of your IP address, mixed with a secret - never the address itself - for three days, then deletes it.
- Asteroids leaderboard
- Only if you submit a score in the hidden Asteroids game: the five-character name you type, your score, the wave you reached, what ended the run and the date go on the public board. The same kind of IP hash is stored with the entry so each player keeps one score per name, and it stays for as long as that score does.
The small print, kept small.
No third-party analytics, ads or trackers - the counters run on the site’s own Cloudflare domain. They are best-effort and approximate. If a count can’t be sent - because you are offline, or the request is blocked - the site keeps a small local note of just the extension and whether it was supported (never the name, size or contents) and sends it the next time you are online, so an aggregate count isn’t lost. Stay offline for good and nothing ever leaves your device. Like any website, the host sees basic request data such as IP addresses to serve pages; Analyser keeps no log of those requests, and stores only what is described above.
