This policy explains what Etoolzy collects when you use http://etoolzy.com, why, and what choices you have. It is written to be read, not to be skimmed past — if anything here is unclear, email contact@etoolzy.com and we will explain it.
1. The short version
- Whatever you type into a tool stays in your browser. Our converters and calculators run entirely on your device using JavaScript. The text, dates, marks or numbers you enter are never sent to us, never stored, and are gone the moment you close the tab.
- We do not ask you to register, and we do not run user accounts.
- We do collect anonymous usage statistics, and we show advertising. Both of those use cookies, and both are described below.
2. Information we do not collect
We do not collect your name, email address, phone number, postal address, payment details or any government identifier, because nothing on this site asks for them. The only exception is the contact form: if you choose to write to us, you send us your name, your email address and your message so that we can reply.
3. Information collected automatically
Like nearly every website, our server and our analytics provider record standard technical information when a page is requested:
- IP address (used to derive an approximate country or city, not an exact location)
- Browser type and version, operating system and device type
- The page you visited, the page that referred you, and the date and time
This tells us which tools people find useful and where the site is slow. It is not used to identify you personally, and we do not attempt to link it to a real-world identity.
4. Cookies
A cookie is a small text file a site stores in your browser. Etoolzy and the services we use set them for three purposes:
- Your preferences. Local storage remembers your light or dark theme choice and the tools you have opened recently, so the site behaves the way you left it. This never leaves your device.
- Analytics. Google Analytics sets cookies to count visits and see which pages are read. The data is aggregated.
- Advertising. Google AdSense and its partners set cookies to choose which ads to show and to limit how often you see the same one.
You can block or delete cookies in your browser settings at any time. The tools will keep working — only your saved preferences and the relevance of the ads will change.
5. Google AdSense and advertising
This site is supported by advertising, which is what keeps every tool free to use.
- Google, as a third-party vendor, uses cookies to serve ads on Etoolzy.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and other sites on the internet.
- You can opt out of personalised advertising by visiting Google Ads Settings. Opting out does not remove ads; it makes them less relevant to you.
- You can also opt out of third-party vendors' use of cookies for personalised advertising at aboutads.info/choices or optout.networkadvertising.org.
- Third-party vendors and ad networks other than Google may also serve ads on this site and set their own cookies, each under its own privacy policy.
If you are in the European Economic Area, the United Kingdom or Switzerland, Google will ask for your consent before using cookies for personalised advertising, and you can change that choice at any time through the consent prompt.
6. Google Analytics
We use Google Analytics 4 to understand which tools are used and how people arrive at the site. It processes the technical information listed in section 3. You can prevent it entirely with the Google Analytics opt-out browser add-on.
7. Other third parties
| Service | What it does here |
|---|---|
| Google AdSense | Serves the advertising that funds the site |
| Google Analytics | Anonymous traffic statistics |
| Google Fonts | Loads the typefaces the site is set in |
| Our web host | Stores the site's files and keeps standard server access logs |
Each has its own privacy policy governing what it does with the data it receives.
8. Data you enter into the tools
This is worth repeating on its own. Text pasted into the Krutidev converter, a date of birth in the age calculator, marks in a rank predictor, a password generated here, the contents of a QR code — all of it is processed by JavaScript inside your browser. None of it reaches our servers, so there is nothing for us to store, sell, leak or hand over. Disconnect from the internet after the page has loaded and the tools still work.
9. Children
Etoolzy is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information through the contact form, email us and we will delete it.
10. Your rights
If you are in India, the Digital Personal Data Protection Act, 2023 gives you the right to access, correct and erase personal data held about you, and to complain to the Data Protection Board.
If you are in the EEA or UK, the GDPR gives you rights of access, rectification, erasure, restriction, portability and objection, and the right to withdraw consent for cookies at any time.
If you are in California, the CCPA gives you the right to know what personal information is collected and to ask that it be deleted. We do not sell personal information.
Because we hold no accounts and no database of visitors, there is usually nothing personal for us to retrieve or delete — but write to contact@etoolzy.com and we will act on any request within 30 days.
11. Data retention and security
Contact-form messages are kept only as long as needed to answer them. Server logs are rotated by our host on its own schedule. The site is served over HTTPS, and the admin area is protected by a hashed password, rate-limited sign-in and CSRF protection. No site can promise perfect security, but there is very little here worth stealing, which is by design.
12. Links to other sites
Our pages and our ads link to sites we do not control. Once you follow such a link, this policy no longer applies, and we are not responsible for the content or privacy practices you find there.
13. Changes to this policy
We may update this policy as the site changes or the law does. The date at the top always reflects the current version, and material changes will be noted on this page.
