Who

Independent project — free tools, no ads, no account. Warranty dates, status, and speed figures come from public sources (OEMs, vendor status pages, M-Lab). Treat PIXELBENCH as a first look; if a number matters, confirm it on that source.

Not affiliated

PIXELBENCH is not affiliated with, endorsed by, or partnered with Lenovo, Dell, Apple, PayPal, Measurement Lab, OBS, Twitch, YouTube, or any other brand named on the site. Names are used only so you know which serial or test you are running.

Warranty results

Coverage dates, product names, and chip guesses are unofficial. They can be wrong, incomplete, or out of date. Always confirm on the manufacturer site before you buy AppleCare, ship a machine, or skip a claim:

• Lenovo — pcsupport.lenovo.com
• Dell — dell.com/support
• Apple — checkcoverage.apple.com

PIXELBENCH offers the lookup as-is, with no warranty of its own. We do not guarantee uptime, accuracy, or that an OEM will keep answering our requests.

Service status

The status board reads public JSON from each vendor’s official status page (Atlassian Statuspage, Google Workspace incidents, Slack Status, Stripe status). It is not Downdetector, not user reports, and not affiliated with those companies. We cache for about five minutes. If a card is wrong, trust the linked official page.

Speed test

The line test uses NDT7 on Measurement Lab (M-Lab), an open research platform. Locate picks the nearest public NDT node (~10 s down, ~10 s up). That is your path to that node, not to Ookla or Netflix. Results will differ from Speedtest.net / fast.com. Casual check only — do not cite PIXELBENCH in a report. The measurement (IP, ISP path, throughput) is sent to M-Lab and kept for research under M-Lab's privacy policy. We do not store speed results. Step-by-step: How we test.

Hourly wipe

We delete our in-memory warranty cache every hour (HMAC-SHA256 keys with a server-side pepper — not a plain hash of the serial). Serials are not written to a database. We cannot delete what Lenovo, Dell, or Apple already have, or the host’s own access logs (time, IP, URL — serial is not in the URL).

What we store

Keyboard, microphone, speakers, camera, gamepad, pixel, motion, and file hashes stay in the browser tab. We do not upload recordings, photos, or key logs. The clock check only asks our server for the current time.

Warranty scans (including Lenovo bulk CSV) go through our server to the OEM for that one request. We do not write serials to a database or to application logs. See Hourly wipe above. Bulk CSV results live in your tab until you close it — a 20-minute run is not cut off by the hourly wipe. We do not require an account.

Apple Check Coverage has no public API. If you complete the captcha here, we forward it to Apple on your behalf for that one lookup. That is unofficial. If Apple or another OEM blocks us, use their site instead.

Public IP / ISP shown on Speed Bench come from Cloudflare and ipwho.is at the moment you open the page. We do not keep a history of those lookups.

Mail DNS reads public SPF, DKIM, DMARC, MX and related records through public resolvers (1.1.1.1 / 8.8.8.8). We do not send email, we do not change DNS, and we do not store the domain you typed.
