1. Overview
This Privacy Policy describes how CalcoraTools ("we", "us" or "our"), operated at calcoratools.com, handles information when you visit and use our website. It applies to all visitors and users of any tool, calculator or feature available on the platform.
CalcoraTools is a free online calculator platform providing tools for health metrics, pregnancy tracking, nutrition planning, document conversion and finance calculations. Because all calculations and file processing occur entirely within your browser, our data handling obligations are minimal by design — not by accident.
By using CalcoraTools, you acknowledge that you have read and understood this Privacy Policy. If you do not agree with any part of this policy, please discontinue use of the website.
2. Data We Collect
We distinguish clearly between two types of data: tool input data (the values you type into our calculators) and standard website analytics data (technical information collected automatically by web infrastructure). These are handled very differently.
| Data Type | Collected? | Where Processed | Stored on Server? |
|---|---|---|---|
| Calculator inputs (age, weight, height etc.) | ✅ You enter it | Your browser only | ❌ Never |
| PDF files you upload or convert | ✅ You provide it | Your browser only | ❌ Never |
| IP address | ✅ Automatically | Server logs | ⚠️ Briefly, then deleted |
| Browser & device type | ✅ Automatically | Analytics | ✅ Anonymised aggregate |
| Pages visited & duration | ✅ Automatically | Analytics | ✅ Anonymised aggregate |
| Name, email, phone | ❌ Never | N/A | ❌ Never |
| Health or medical records | ❌ Never | N/A | ❌ Never |
The only data that ever leaves your device is standard, anonymised web traffic metadata — the same information any web server collects when you visit a page. This data cannot identify you personally and is used solely to maintain website performance and security.
3. How We Use Data
The limited technical data we receive through server logs and analytics is used exclusively for the following purposes:
- ✓Website performance monitoring — identifying slow-loading pages or tool errors so we can fix them quickly.
- ✓Security and fraud prevention — detecting abnormal traffic patterns, bot activity or attempted attacks on our infrastructure.
- ✓Aggregate usage analytics — understanding which tools are most popular so we can prioritise improvements and add new free online calculators.
- ✓Legal compliance — retaining minimal records as required by applicable law or in response to lawful requests from authorities.
- ✗We do not use any data for targeted advertising, user profiling, behavioural tracking or sale to third parties.
- ✗We do not combine anonymised analytics with any personal identifier to create individual profiles of any user.
4. Cookies & Local Storage
CalcoraTools uses a minimal number of cookies and browser storage mechanisms. We do not use advertising cookies, retargeting pixels or cross-site tracking technologies of any kind.
You can manage, restrict or delete cookies at any time through your browser settings. Please note that disabling essential cookies may affect how some tools display or function. For guidance on cookie management, refer to your browser's help documentation.
5. Third-Party Services
To operate and maintain CalcoraTools, we rely on a small number of trusted third-party services. Each is listed below with a description of what data they may receive and why.
| Service | Purpose | Data Shared |
|---|---|---|
| Web Hosting Provider | Serving website files to your browser | IP address, page requests (standard server logs) |
| Google Fonts | Loading the Cabinet Grotesk and Instrument Sans typefaces | IP address, browser type (per Google's privacy policy) |
| Analytics Provider | Aggregate, anonymised usage statistics | Anonymised page views, device type, referral source |
| Content Delivery Network | Fast delivery of website assets globally | IP address, request metadata (standard CDN logs) |
We do not share your tool inputs, health data or document contents with any third party under any circumstances. We do not sell data to data brokers, advertisers or any other commercial entity.
6. PDF Tool Privacy
Our PDF converter and related tools use open-source browser APIs to handle document conversion, compression, merging and splitting. When you use any of our PDF tools:
- ✓Your file is loaded into browser memory only and is never transmitted over the internet to any server.
- ✓All conversion, compression and splitting operations run as JavaScript in your own browser tab.
- ✓The output file (JPG, PNG, compressed PDF etc.) is generated locally and downloaded directly to your device.
- ✓When you close or refresh the browser tab, all file data is cleared from browser memory automatically.
- ✗We have zero technical ability to access, read or store the contents of any document you process with our tools.
This architecture was chosen deliberately to protect user privacy — particularly for sensitive documents such as financial statements, medical records and legal files.
7. Health Calculator Data
Our health, fitness and nutrition tools — including the BMI calculator, TDEE calculator, body fat calculator, pregnancy calculator and all related tools — require you to enter personal metrics such as height, weight, age and cycle dates.
We treat health and body metric data as especially sensitive. Our commitment for this category of data is absolute:
- ✗We do not collect your height, weight, age, body fat percentage, BMI result or any other health metric.
- ✗We do not collect pregnancy dates, last menstrual period, due date or any reproductive health information.
- ✗We do not link anonymous analytics data to health inputs entered into any tool.
- ✗We do not share health data with insurers, employers, healthcare providers or any third party — because we do not have it.
All calculator results are shown to you in your browser and disappear when you navigate away or reload the page. Nothing is saved, logged or retained by us in any form.
8. Children's Privacy
CalcoraTools is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13 years of age. Because our tools do not collect any personal data from any user, the risk of inadvertent collection from minors is minimal by design.
If you are a parent or guardian and believe that a child under your care has provided personal information to us — for example, through a contact form — please reach out via our contact page and we will promptly review and address the matter.
9. Your Rights
Depending on the country or region in which you reside, you may have specific legal rights regarding your personal data. Because CalcoraTools does not collect or store personal data from tool usage, most data rights requests are satisfied automatically — there is simply no personal data on record to access, correct, or delete.
10. Security
We apply industry-standard security measures to protect the CalcoraTools website and its infrastructure. Our security approach includes:
While we implement reasonable security measures, no system connected to the internet is completely invulnerable. We encourage users to keep their browsers up to date and to use secure networks when accessing any website.
11. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices, technology or legal obligations. When we make changes, we will update the Last Updated date displayed at the top of this page and in the sidebar.
For material changes — those that meaningfully affect how we handle user data — we will make a reasonable effort to notify users by placing a prominent notice on our homepage for a period of no less than 30 days following the update.
We encourage you to review this Privacy Policy periodically. Your continued use of CalcoraTools after any changes have been posted constitutes your acceptance of the updated policy. If you do not agree with the updated terms, you should discontinue use of the platform.
