The short version
Almost every tool on this site runs entirely in your browser. Whatever you type into a calculator, converter, text tool, QR/barcode generator or image tool is processed on your own device and is never sent to our servers. There are no accounts, no sign-up, and no newsletter. There are exactly two things that touch a server, both described below, plus some data your browser stores locally on your own device.
What we do not collect
- No account information — there is no sign-up anywhere on this site.
- No calculator, converter or tool input — none of it is uploaded, logged or stored.
- No files you process with an image, PDF or text tool.
- No email address, unless you choose to email us.
- No cross-site tracking of you personally, and no data is sold to anyone.
The two exceptions that do touch a server
1. The URL shortener
The URL shortener tool cannot work entirely client-side — a short link has to keep working from any device, at any time, which means the mapping from a short code to its destination has to live somewhere durable. When you shorten a link, we store the destination URL and a click counter on the server. That is the only tool on the site that stores what you gave it. No other information about who clicked the link is recorded.
2. Page-view analytics (only if enabled)
If the site owner has switched on page-view analytics, a first-party, self-hosted system (not Google Analytics, not any third party) records, per page view:
- the path you visited (e.g.
/math/percentage-calculator), - the host of the site that referred you, if any — just the domain, e.g.
google.com, never the full URL, search terms or query string, - a coarse device class — mobile, tablet or desktop — derived from the browser's user agent,
- a two-letter country code. Where the hosting provider or CDN in front of the site attaches one to the request (for example Cloudflare's
cf-ipcountryheader), we use that. Where it does not, we fall back to the region already present in your browser'sAccept-Languagepreference — so a browser set to en-GB is counted as GB. That is a rough hint rather than your location, and a language sent without a region is recorded as unknown. We never look up your IP address and never store it, - roughly how long the page stayed open and visible in your tab (rounded to the nearest second, capped at 30 minutes), so the site owner can tell which pages hold attention. Time spent with the tab in the background, minimised, or on another tab is not counted,
- a random id generated in your browser's
sessionStorage(never a cookie, neverlocalStorage), used only to count how many distinct visits happened that day. It disappears the moment the tab is closed, and only a same-day tally of distinct ids is kept — the id itself is never written to the server's database.
Everything above is aggregated into daily totals. This system sets no cookies, assigns no persistent identifier to you, and cannot link two separate visits (on different days, or after the tab is closed) together as the same person. It exists so the site owner can see which tools are useful, not to track individuals.
Local storage on your device
Several tools use your browser's own localStorage to remember things between visits: your light/dark theme choice, a list of recently used tools, counter totals in the counter tools, and saved state for tools like the notepad and to-do list. This data lives only in your browser, on your device — it is never transmitted to us or to anyone else, and clearing your browser data removes it.
Cookies
This site's own analytics sets no cookies at all. The only first-party cookie this site ever sets is an admin-session cookie used when the site owner signs in to the admin panel — it has nothing to do with, and is never set for, an ordinary visitor. If advertising is enabled and you accept it, Google AdSense sets its own third-party cookies — see the full breakdown on the cookies page.
Third-party advertising
This site may show ads served by Google AdSense. Google and its advertising partners may use cookies and similar technologies to serve ads based on your visits to this and other websites. Ads only load after you accept them in the cookie consent banner — see Cookies for exactly how that works. You can control the ads you see, or opt out of personalised advertising, using:
- Google's Ads Settings: adssettings.google.com
- Google's explanation of how it uses data from partner sites: policies.google.com/technologies/partner-sites
- The Network Advertising Initiative's opt-out page (covers many ad networks at once): optout.networkadvertising.org
Children's privacy
This site is not directed at children, does not knowingly collect personal information from anyone, and has no age-gated features because it has no accounts. If you believe a child has provided personal information to us — most plausibly by email — contact us using the details below and it will be deleted.
Your rights (GDPR / CCPA)
Because this site does not collect personal data through normal use, there is very little to request access to, correct or delete. If you are in the EU/EEA/UK or California and want to exercise a right under GDPR or the CCPA — access, correction, deletion, or an objection to processing — contact us below. Where a right relates to data a third party like Google holds on their own systems (for example, advertising identifiers), it needs to be exercised with that party directly using the links above; we do not hold or control that data ourselves.
Data retention
- Short links: kept indefinitely so they keep working, unless the owner deletes one.
- Page-view analytics: aggregated daily counts with no personal identifiers, kept for as long as the site owner finds the trend data useful.
- Local storage on your device: kept until you clear your browser data or the site removes it programmatically; never sent to us.
