Privacy Policy

Last updated: October 21, 2026

This policy explains what happens to information when you use Reeliy (https://reeliy.com): what we collect, why we collect it, who else is involved, how long it is kept, and what you can do about it.

The short version: Reeliy is a collection of free calculators and converters. There are no accounts, and the calculations run in your browser: the site never uploads the numbers you type. The personal data we deal with comes from standard server logs, from any email you choose to send us, and from the Google services described below. One thing to know: once you press the button (or “Reload page” when a page could not finish loading), what you typed is added to the page address, so treat that address as something other people can read, and do not type secrets into a tool (see “Calculator values and the page address”). A few conveniences, such as tools you save, the last tools you opened, your unit system, and copies of pages for offline use, are kept in your own browser only (see “Preferences and offline storage”).

Who is responsible for your data

Reeliy is operated by Fikrra Plus Research and Development in Educational Technology L.L.C. S.P.C. (“we”, “us”). We decide how the data described in this policy is used on our site, so we are the party responsible for it under data protection laws such as the GDPR, the UK GDPR and California privacy law.

Google decides for itself how it uses certain advertising data, as explained in “Advertising and how Google uses data” below.

Our postal address is Seih Shuaib 3, WHF2 Block-A Commercial, P.O. Box 11111, Dubai, United Arab Emirates. It is given so that you know who is responsible; for privacy questions and requests, please use email, at support@reeliy.com. See also our contact page.

What we collect automatically

The information involved when you visit is listed below. What the Google services receive depends on your region and your cookie choice (see “Your consent choices” below). Server logs are kept whichever choice you make.

Analytics data. We use Google Analytics 4 (GA4) to measure traffic. It records which pages are viewed (by their address without the query string or anything after “#”), your approximate location at country or city level (worked out from your IP address, which GA4 does not log in full), your device and browser type, and the page that referred you (and, when the link you came by carried campaign tags such as utm_source, those tags). A visit from a browser that carries the site owner’s switch (described in the Cookie Policy) is labelled as internal traffic. GA4 sets first-party cookies to tell visits apart.
Product events and page speed. When you use a feature, Google Analytics also receives a small event: for example that a result was calculated, copied, shared or printed, that a tool was saved or unsaved, that units were swapped, that search was opened or a result chosen, or that the install button was used. An event names the tool (such as “calculator/bmi-calculator”) or a fixed label, such as the share method. It never includes what you typed, a search term, a result or an address with a query string. We also send page speed timings (Largest Contentful Paint, Interaction to Next Paint, Cumulative Layout Shift, First Contentful Paint and Time to First Byte) as rounded numbers together with the page path, so that we can find slow pages. When a script on one of our pages stops working, Google Analytics also receives a small error report, so that we notice a broken release early. An error report holds the page path, the kind of failure (a script that threw an error, a promise that was not handled, or a script or stylesheet that did not download), the type of error, a short generic description, and the name of the script file with the line and column where it failed. The description is rebuilt from a fixed list of common error words, so the error message itself is never sent: words that are not on the list and quoted text are left out. The file name is the last three parts of the script’s path on our site. At most three different errors are reported each time a page is loaded, and errors from browser extensions or from other sites’ scripts are not reported.
Advertising data. We show ads through Google AdSense. Google and its advertising partners may read or set cookies and identifiers in your browser so that ads can be delivered, limited in frequency, checked for fraud and measured. With your consent, they may also be personalized.
Server logs. Like almost every website, the infrastructure that serves our pages records each request: your IP address, user agent (browser and device details), the address requested, the time, and the response status. When a page is reloaded or opened from a link that holds values, the address requested includes them (see “Calculator values and the page address”). These logs are kept for security, abuse prevention and running the service.
Your consent choice. When you answer the cookie dialog, your choice is stored in your own browser, as described below. It is not sent to us.

What you send us

If you email support@reeliy.com, we receive your email address, your name if it appears in the message, and whatever you write. We use it only to reply, to keep a record of the correspondence, and to handle privacy requests. We keep it only as long as it is needed for those purposes.

Please do not include sensitive details (such as health or financial information) in an email unless it is necessary for your question. If you send a link to a calculation, remember that the link contains the numbers entered.

What we do not collect

We receive no data from any of the following, because the site has no such feature or because the information is kept in your own browser:

Accounts. There is no registration, login or user profile.
Calculator inputs, as such. Calculations run in your own browser, and the site never uploads what you type: no form sends your input to us. (After you press the button, what you typed does appear in the page address, and the address reaches our server when you reload the page or open a link that holds it; “Calculator values and the page address” below explains what that means.)
Files. The site has no upload feature.
Messages posted on the site. There are no comments, forums or contact forms.
Your preferences. The tools you save, your list of recent tools, your unit system, and copies of pages kept for offline use are kept in your own browser (see “Preferences and offline storage”). They are not sent to us, and we cannot read them.

Because there are no accounts, we cannot normally tell who a particular cookie set by the Google services belongs to.

Preferences and offline storage

Some features keep information in your own browser, not on our servers: tools you save with the star, the last tools you opened (the recent list), your preferred unit system (metric or imperial), and, so that pages you opened can work without a connection, copies of those pages. We never receive this information, so it is not part of what we collect.

Purpose. To give you the features you ask for: a saved tool is still there tomorrow, your unit system is remembered, the recent list shows the tools you opened last, and a page you opened before can open when your connection drops. It is not used for analytics or advertising, and not to identify you.
What it contains. Tool names such as “calculator/bmi-calculator”, your unit choice, and copies of pages and files from this site. It never contains numbers you typed, search terms or results. A copy of a page is saved under its address without the query string.
How long. Until you remove it. Un-star a tool to remove it from the saved list. Use “Clear recent” (or “Clear” beside the recent list) to empty the recent list. It holds the last tools you opened in this browser only, and it fills again as you open tools. Clearing this site’s data in your browser settings removes everything, offline copies included. Private windows discard it when they close.
Who gets it. Nobody. It is not sent to us or to anyone else.

Because it only provides features you ask for and is kept on your device alone, it is not tied to the choice you make in the cookie dialog.

If your browser blocks storage, every tool still works; your saved tools, recent list, units and offline use are simply not remembered. Names and details of each item are in our Cookie Policy.

Calculator values and the page address

When you press Calculate, Convert or Generate, the values you entered are added to the page address, for example ?mass=70&height=170. We do this so that you can bookmark a calculation, reload it or send it to someone. The same applies to text you type into a tool, such as a list of names or a string to hash, and to the phrase you search for on the search page, which is added to that page’s address. The “Reload page” button that appears when part of a page could not be downloaded (for example after the site was updated while the page was open) does the same with the values you entered before it reloads the page, so that they are still there afterwards; a tool with a large text box leaves its values out. The calculation runs in your browser, and no form sends what you type to us. But an address is not private, and these are the places it can end up:

Your own browser and the people around it. The address is kept in your browser history, in bookmarks and in the tabs your browser restores later. Anyone who can see your history, your bookmarks or your screen can read it, and so can the people you send the link to.
Share destinations. The share buttons under a result (Facebook, X, LinkedIn and email), your device’s own share sheet when it opens one, and “Copy link” use only the tool’s own address, without your numbers. “Copy link with my values” and the address in your browser’s address bar do contain them, so whatever site or app you paste that address into receives them.
Our hosting infrastructure. When you reload the page, or when anyone opens an address that holds values, the browser asks the site’s host for that full address, as it does for any web page. The request, with the values in the address, appears in the server logs described above.
Advertising. Requests for ads include the address of the page, so Google and its advertising partners can receive the numbers as part of it.

Google Analytics is the exception. It is set up to receive the address of each page without the query string and without anything after “#”, which is where the numbers sit, and a referrer from this site is trimmed the same way. The numbers are therefore not part of what it receives. The one part of a query string that is passed on is a campaign tag of the link you arrived by (utm_source and the like), as a separate field and only when it is short plain text; calculator values are written under other names, so they are not among them.

One limit on how far it travels: when a page of this site asks for scripts, styles or other files, or you follow a link from it to another website, your browser passes on only the site’s own name (https://reeliy.com) as the referrer, not the full address with your values.

So please do not type passwords, keys or other secrets into a tool, and do not share, post or bookmark the address of a calculation whose values you want to keep to yourself, for example health measurements, income or savings figures, or a list of names. To share a tool, use “Copy link” rather than “Copy link with my values”; if you want to share only a result, copy the result. The same applies inside an embedded widget (see below).

Embedded widgets

Other websites can show one of our tools in a frame, using the embed code from our Widgets page. The framed page contains only the tool: no header or footer, no cookie dialog, and no Google Analytics or AdSense scripts. It sets no cookies and stores nothing in your browser.

A framed tool is still a page served by our hosting infrastructure, so loading it is logged like any other request (IP address, browser details, the widget’s address, time and response status). Your browser may also tell the server which page embeds the widget; browsers by default send only the name of the embedding website, not its full address, but the embedding page can choose to send more. The calculation runs in your browser. A widget has no share buttons, but after you press its button the numbers appear in the widget’s own address, and the same cautions apply as described above. The website that embeds the widget cannot read what you type, because the widget runs on our domain. That website has its own privacy practices, which we do not control.

Why we use data, and our legal bases

If the GDPR or UK GDPR applies to you, for example because you are in the EEA or the UK, we need a legal basis for each use of your personal data. Ours are:

Measuring traffic with analytics. Basis: your consent. In the EEA, UK and Switzerland, analytics storage starts off and Google Analytics sends only limited pings that do not use cookies until you click “Accept all”. We use the results to see which tools are used and to decide what to improve.
Showing and measuring advertising, including personalization. Basis: your consent. In the EEA, UK and Switzerland (judged from your browser’s time zone) the ad library is not requested, and no ads are shown, until you click “Accept all”. Elsewhere ads are shown by default, and “Essential only” or a Global Privacy Control signal makes them non-personalized. Advertising is how the site pays for itself.
Remembering your preferences and offline copies. These stay in your browser and are not sent to us. We store them to provide the features you ask for: a saved tool, your unit system, a page that opens without a connection.
Server logs. Basis: our legitimate interests in keeping the site secure, preventing abuse and keeping it running.
Answering your emails and handling privacy requests. Basis: our legitimate interests in responding to the people who contact us, and, where a request is made under privacy law, our need to comply with that law.

Where we rely on consent, you can withdraw it at any time (see “Your consent choices”). Withdrawing does not affect anything done before you withdrew.

Cookies and similar technologies

Cookies are small files that a website stores in your browser. Similar technologies, such as local storage, do the same job. We and our partners use the following.

Analytics cookies. The cookie _ga and a second cookie whose name starts with _ga_ and ends with our analytics container ID. They are first-party cookies and typically last up to two years.
Advertising cookies. Google and its partners may use identifiers such as __gads, __gpi, IDE, test_cookie and DSID. Durations vary, from minutes up to about 13 months.
Local storage. Our site saves your dialog choice in your browser’s local storage under the key consent_v1. It exists only to remember your choice, is not an advertising or tracking identifier, and is not sent to our servers. If you close the dialog without choosing, a small marker, consent_dismissed_v1, is kept in your browser’s session storage so the dialog stays closed in that tab; it disappears when the tab closes.

Your own preferences and the offline copies are kept in local storage and cache storage; “Preferences and offline storage” above describes them. Our Cookie Policy gives more detail about each item and how to control it.

You can also install the Google Analytics Opt-out Browser Add-on to stop Google Analytics from collecting data about your visits to any site.

Advertising and how Google uses data

Ads on Reeliy are served by Google AdSense. When an ad loads, Google and its ad partners can receive technical information from your browser, such as your IP address, device details, the address of the page and the identifiers listed above. They use it for ad delivery, frequency capping (not showing you the same ad too often), fraud prevention and measurement, and, depending on your region and your cookie choice, to personalize the ads you see. When personalization is on, that can mean ads based on your earlier visits to this site and to other websites.

Third-party vendors, including Google, use cookies to serve ads based on your earlier visits to this site or to other websites. The advertising cookies Google uses let it and its partners show you ads that reflect those visits.

Google explains how it handles data from sites like ours at How Google uses data from sites or apps that use its services. You can opt out of personalized advertising in Google’s Ads Settings, and you can opt out of other companies’ use of cookies for personalized advertising through the industry tools. The links are:

We do not sell personal information for money. However, advertising partners may receive identifiers from your browser so they can deliver ads, and under California law that can count as “sharing” for cross-context behavioral advertising. Ads never influence how our calculators work; see our Advertising Disclosure.

International transfers

Our hosting infrastructure serves pages from servers in many countries, so a request may be handled outside your own country. We rely on the safeguards that provider offers for such transfers.

Google may process data in countries other than your own, including the United States. Where the law requires safeguards for such transfers, Google relies on measures such as Standard Contractual Clauses and, where applicable, the EU-US Data Privacy Framework.

How long we keep data

Cookies. They last for the periods described above, unless you delete them sooner.
Data held by Google. Google keeps the data from the services described above under its own retention rules.
Server logs. They are kept only as long as needed for security, abuse prevention and operations, following the hosting infrastructure’s own retention routine.
Emails. They are kept only as long as needed to respond, to keep a record of the correspondence and to handle any privacy request.
Consent choice. It stays in your browser until you clear site data.
Preferences and offline copies. They stay in your browser until you remove them (see “Preferences and offline storage”). We hold no copy.

Security

We take reasonable measures to protect the data we handle. Because the site never uploads what you type and there are no accounts, there is less for us to protect than on a typical website. Still, no system connected to the internet is completely secure, and we cannot guarantee absolute security.

Your rights under California law (CCPA/CPRA)

If you live in California, you have the right to:

know what personal information we collect, use, disclose and share
delete personal information we have collected from you
correct inaccurate personal information
opt out of the sale or sharing of your personal information
not be treated differently for using these rights

We collect the kinds of information described above: identifiers such as IP addresses and cookie IDs, internet activity such as pages viewed, approximate location, and device and browser details. We collect them from your browser and use them for analytics, advertising, security and operations. We disclose identifiers and internet activity data to Google and its advertising partners for those analytics and advertising purposes. We do not sell personal information for money.

To opt out of the sharing described above, use the “Do Not Sell or Share My Personal Information” link in the footer of any page. It opens the cookie dialog; choose “Essential only”. That applies immediately: Google’s tags are told to deny ad storage, ad personalization and analytics storage, ads are requested as non-personalized, and your choice is saved in this browser for later visits. You can also send a Global Privacy Control signal from your browser (when you have not made a choice in the dialog, we treat it as the same opt-out; a choice you make in the dialog takes priority), use the Google tools listed above, or email us.

To use your other rights, see “How to make a request” below.

How to make a request

Email support@reeliy.com, say which right you want to use and, if you are in California, say so. We aim to reply within one month for GDPR and UK GDPR requests and within 45 days for California requests.

We may ask for details that help us confirm the request is genuine. Since we have no accounts, we usually cannot link cookie data from the Google services to an email address. In that case we will say what we can do and point you to the controls offered by Google.

Children

Reeliy is a general-audience site and is not directed at children under 13 in the United States, or under 16 in the EU (or the lower age that local law sets). We do not knowingly collect personal data from children below those ages. If you believe a child has sent us personal data, email support@reeliy.com and we will delete what we hold. We have no actual knowledge that we sell or share the personal information of anyone under 16.

Some tools, such as the percentage, grade and fraction calculators, are useful to students, and some students are under 13. We write the tools and text for a general audience, there is no sign-up, and the site never asks for anyone’s age.

Because the site is not directed at children, we do not ask Google to treat its visitors as children for advertising. A parent or guardian who does not want a child to receive personalized ads can switch them off for that browser with the tools listed under “Advertising and how Google uses data”.

Third-party links

Our pages, and the ads on them, may link to other websites. We do not control those sites and are not responsible for their privacy practices. Read their policies before sharing any information with them.

The share buttons under a result open Facebook, X, LinkedIn or your email program with the tool’s address filled in, without the numbers from your calculation (see “Calculator values and the page address”). What those services do with it is governed by their own policies.

Changes to this policy

We will update this policy if what we do with data changes, for example if we add a new tool or partner. The “Last updated” date at the top of the page changes whenever we make a substantive change, so check it if you want to know whether anything is new. See also our Terms of Use.
