What stays on the device you used

Most privacy conversations about a rating tool are about the server: what it stores, for how long, who can see it. The device you used has its own copy of some of that, and it is usually the easier one for another person to find.

What actually gets left behind

A browser keeps a local cache of the pages and images it has recently loaded, so the result page and the thumbnail on it can sit in the cache folder well after the tab is closed. The address bar's autocomplete remembers the URL, and if the URL itself carries a score or an id in it, that string sits in history in plain view. If you typed an email address into a form on the way to a result, the browser's autofill may have offered to remember it, and once accepted that suggestion persists until it is deleted by hand. Anything you saved deliberately - a screenshot, a downloaded verdict image - lands in the downloads folder like any other file, with no special handling at all.

None of this needs the service to have done anything wrong. It is what a browser does by design, on every site, because caching and autocomplete are what make the web feel fast. A rating result is not treated differently from a recipe page, and that is exactly the problem: nothing on your end knows the content was sensitive.

The parts that live outside the browser

Browsers are not the only thing keeping a copy. Search bars in the address bar or the operating system's own launcher often index recently visited pages by title, and a page titled with a score or a verdict can surface as a suggestion the next time someone starts typing a similar word, independent of anything the browsing-data setting touches. Share sheets remember recent destinations too, so if a result was ever shared to a messaging app or copied to a note, that action is itself a small piece of history sitting in a different app entirely, with its own separate clearing process. On a phone, the "recent apps" switcher can hold a live screenshot of whatever was on screen when you last left the app, which is a second image of the result existing outside any cache folder and outside any setting labelled privacy at all. None of these are hidden or unusual behaviours - they are ordinary conveniences every app on the device provides - but they explain why clearing one browser's history rarely feels like it fully closes the loop.

Why it is worse on a shared machine

On a device only you use, this is mostly academic - the risk is whoever gets physical access to your own laptop, which is a narrower threat than most people worry about. On a family computer, a work laptop, or a phone someone else sometimes borrows, it is a live one. History and autofill are visible to anyone who opens the same profile, and a cached thumbnail can be recovered without any technical skill, just by scrolling back or reopening a recent tab. The device-specific version of this problem - logged-in sessions, saved passwords, and what a second user of the same phone can see - is its own subject and worth reading before assuming a shared device is fine as long as you log out.

What actually clears it

Private or incognito browsing avoids most of this by design: no history entry, no cache retained after the window closes, no autofill offer saved. It is the simplest fix for a one-off visit and costs nothing. Google's Chrome help page on Incognito says that on exit Chrome keeps no "site data or a record of the sites you visited," but also that it "retains bookmarks that you save and files that you download." For a browser already carrying history from before you started being careful, "clear browsing data" for cache, cookies and history covers the same ground retroactively, and most browsers let you scope it to a time range rather than wiping everything. The downloads folder is not covered by any of that and has to be checked and cleared separately, since a saved image is a file like any other and browsing-data tools do not touch it.

Notifications are a separate leak with the same shape - a result that never touches your browser history can still appear in a lock-screen preview - and that path is covered on its own rather than folded in here.

Where this fits against the rest of the picture

Local traces answer a different question from server-side retention. What actually happens to a file after you upload it is about the service's side of the exchange, and reading both closes the loop rather than half of it. Rate Cock's result pages work the same way any web page does - cached, addressable, revisitable - which is convenient and is also the property this article is about. Other rating tools carry the same local footprint regardless of what they promise server-side, a point Penis Rater's tools coverage returns to from the product side. If a result came from a commissioned human review rather than a model, the review itself lives on the reviewer's platform and outlives anything in your browser - Rate Penis's review pages are the record that persists regardless of what you clear locally. A measurement session logged elsewhere follows the same local-cache rule, which Measure My Cock's data page covers for its own kind of session.
