Privacy Policy for OfficeCalculator.Net
Last updated: September 20, 2026
This Privacy Policy explains what information OfficeCalculator.Net processes when you use our calculators, learning tools, Kids Section, analytics, advertising and contact features. We aim to collect only what is useful for operating and improving the site and to explain those practices in plain language.
1. Scope of this policy
This policy applies to OfficeCalculator.Net and its pages and tools, including the dedicated Kids Section. It does not control the privacy practices of websites that we link to. If you follow a link to another website or service, that provider's privacy policy applies there.
OfficeCalculator.Net does not currently require a user account to use its public calculators or Kids Section.
2. Calculator and tool data
Most OfficeCalculator.Net tools perform calculations in the browser. Unless a tool clearly says otherwise, the numbers or text you enter are used to produce the result on your device and are not intentionally included in our first-party analytics requests.
Some browser features may save preferences locally on your device, for example theme choices, favorites or tool settings. Clearing browser site data can remove these local preferences.
3. First-party traffic analytics and live traffic
We operate a lightweight first-party analytics system to understand site traffic, keep tools working well and identify which pages are useful. It is hosted with OfficeCalculator.Net rather than being an advertising profile.
| Data | How we use it |
|---|---|
| Pseudonymous visitor and session identifiers | Count approximate unique visitors and sessions. The server stores hashed versions of these identifiers. A browser-side identifier may remain in local storage until you clear site data. |
| Page path and referrer/source | Measure page views, top pages and general traffic sources. |
| Device class | Understand use on mobile, tablet and desktop so we can improve responsive design. |
| Browser time zone and locale | Help produce a best-effort country label when a hosting/CDN country code is unavailable. |
| Country code, when available | Show general country-level traffic. This may come from hosting/CDN headers, local server GeoIP capability, browser time zone or locale. It is not intended as precise location tracking. |
| Last-seen time | Power the private “Live Now” dashboard and show which page an active visitor is viewing. |
Our private dashboard treats a visitor as “live” for approximately five minutes after the latest activity. Active-visitor records are automatically cleaned after approximately 24 hours. Daily first-party analytics and daily backups are retained for up to 90 days, after which the system deletes older records as part of routine maintenance.
Our first-party analytics system does not intentionally store raw IP addresses in its traffic database. Our web host and security infrastructure may still process IP addresses in ordinary server, security or abuse-prevention logs.
4. Cookies, local storage and similar technologies
OfficeCalculator.Net and services used on eligible pages may use cookies, local storage and similar browser technologies. These can support site preferences, anonymous traffic measurement, security, fraud prevention, advertising measurement and—where permitted—ad personalization.
You can remove or block cookies and local storage through your browser settings. Doing so may reset preferences or affect some site features.
5. Analytics on general-audience pages
Microsoft Clarity
On eligible general-audience pages we use Microsoft Clarity to understand interactions such as clicks, scrolling, navigation, layout behavior, performance problems and session playback. We configure privacy protections for calculator inputs and sensitive result areas where supported. Clarity may use cookies and other identifiers according to Microsoft's own privacy terms.
Yandex Metrica
On eligible general-audience pages we use Yandex Metrica for site analytics such as page usage, navigation, click maps, scrolling, performance and, where enabled, Webvisor session replay. We mark calculator input fields for masking and hide certain result/user-generated areas from replay where supported. Yandex may use cookies and similar technologies according to its own terms.
These third-party analytics tools are not loaded on the current OfficeCalculator.Net Kids Section pages.
6. Advertising
OfficeCalculator.Net uses Google AdSense on eligible general-audience content pages. Google and its advertising partners may use cookies, local storage, device information and similar technologies to deliver and measure advertising and, where permitted by applicable law and user choices, personalize ads.
Where consent is required, a consent message or consent management platform may offer choices about advertising and analytics technologies. You can also manage advertising privacy choices through Google services and your browser.
The current Kids Section does not load Google AdSense advertising. We do not use the Kids Section's first-party analytics identifiers for behavioral advertising, remarketing or cross-site tracking.
7. Kids & children's privacy
How the Kids Section is designed
The OfficeCalculator.Net Kids Section is intentionally designed for children, students, parents and teachers. It does not require an account, and the current Kids tools do not ask a child to submit a name, email address, phone number, home address, photo, voice recording or precise location.
Sound effects are generated in the browser. “Read Number” features use the device/browser's text-to-speech capability; OfficeCalculator.Net does not use that feature to record a child's voice.
Limited first-party measurement
Kids pages use the same limited first-party traffic system described above for internal operations: a pseudonymous visitor/session identifier, page path, general referrer/source, device class, browser time zone/locale, a best-effort country label and last-seen time. Identifiers are hashed on the server and this information is not used to build advertising profiles.
Persistent identifiers can be treated as personal information under children's privacy laws in some circumstances. Our purpose for this limited Kids Section measurement is internal site operation, security, audience counting and improving the service—not behavioral advertising or cross-site tracking.
Parents and guardians
If you are a parent or guardian and believe a child has provided personal information to OfficeCalculator.Net through another part of the site, contact us at quickweblinker@gmail.com. We will review the request and take appropriate deletion or other action where required.
8. Information you choose to send us
If you contact us, we may receive the information you choose to provide, such as your name, email address, message and attachments. We use it to respond to the inquiry, provide support, investigate a problem or handle a privacy request. Please do not use the contact form to send unnecessary sensitive information.
9. Server logs, security and fraud prevention
Like most websites, our hosting and security systems may create technical logs containing information such as IP address, browser/user-agent information, requested pages, date/time, errors and security events. These logs help deliver the site, diagnose failures, prevent abuse and protect the service.
We use reasonable technical and organizational measures appropriate to the site, but no Internet service can guarantee absolute security.
10. Data retention
- First-party daily analytics and backups: up to 90 days.
- First-party active visitor records: cleaned after approximately 24 hours; the live dashboard itself uses an approximately five-minute activity window.
- Browser-side preferences/identifiers: may remain until you clear site data or the relevant feature resets them.
- Contact messages and server/security logs: kept only as long as reasonably needed for the purpose, security, legal obligations or dispute handling.
- Third-party data: retained according to the applicable provider's policies and settings.
11. Your privacy choices and rights
Privacy rights vary by location. Depending on the law that applies to you, you may have rights to request access, correction, deletion, restriction or portability of personal information, object to certain processing, withdraw consent, or opt out of certain targeted advertising, sale or sharing of personal information.
We do not sell personal information for money. Some privacy laws use broader definitions of “sale” or “sharing” that can include certain advertising or cross-context behavioral advertising practices by third parties. Where applicable, use the consent/privacy controls presented on the site or contact us with a request.
California residents may have rights under California privacy law, including rights to know/access, delete, correct and opt out of certain sale/sharing activities, subject to applicable exceptions. Residents of the EEA, UK and other regions may have additional rights under their local data-protection laws.
12. International processing
OfficeCalculator.Net is available internationally. Our hosting and third-party service providers may process information in countries other than the country where you live. Applicable providers are responsible for their own transfer mechanisms and privacy commitments.
13. Third-party services and links
Third-party services have their own privacy practices. Relevant resources include Google Privacy Policy, Google advertising technologies, Microsoft Privacy Statement, and Yandex Privacy Policy.
14. Changes to this policy
We may update this Privacy Policy when the site, technology, legal requirements or service providers change. The “Last updated” date at the top identifies the current version. Material changes affecting the Kids Section will also be reflected in that section.
