Policy scope
This OnlineCalculator.xyz privacy policy is effective August 29, 2026. It describes the public site, local directory filter, browser calculators, hosting requests, and support correspondence. OnlineCalculator.xyz is operated by OnlineCalculator.xyz, 30 N Gould St Ste R, Sheridan, WY 82801, USA. Privacy questions may be directed to support@onlinecalculator.xyz.
The application follows a data-minimization design. Numeric entries, optional calculator labels, directory search phrases, and filter selections are intended to be processed in the visitor’s browser. They are not sent to a remote solver, placed in a personal OnlineCalculator.xyz user profile, attached to analytics, or saved in a cloud history. Loading the website and choosing to send email are separate network activities described below.
Calculator and directory state
Calculator inputs exist in temporary page state for the time needed to validate fields and display a result. Directory phrases are compared with a static catalog in the browser. The application does not put those values in URL query parameters, application logs, analytics events, localStorage, sessionStorage, IndexedDB, cookies, accounts, or remote requests.
Reset removes the visible state from a tool. Closing, reloading, or navigating follows ordinary browser behavior. A browser’s own form restoration or back-forward cache may show a prior value without the website having stored it in an account. Visitors can use browser controls and the page reset button.
The operator ordinarily cannot retrieve, correct, export, or delete a calculation that it never received. Avoid entering confidential information into optional labels or directory phrases. A mathematical field may become personal when combined with outside context even if the field itself contains only a number.
Hosting and request metadata
The planned host is Vercel. To return a page and maintain security, hosting and network systems process technical request information such as IP address, date and time, requested path, status code, user-agent, referrer, and security indicators. Providers may retain operational records according to configured settings, agreements, infrastructure needs, and legal obligations.
OnlineCalculator.xyz may use information it actually receives to deliver pages, investigate errors and abuse, protect the service, and comply with law. The current service includes no third-party audience analytics, behavioral advertising, or joining of calculator inputs with request records. Host logs, headers, cookies, subprocessors, and retention may be governed by provider settings and terms; this policy will be updated if those data paths materially change.
Voluntary email
When a person emails support@onlinecalculator.xyz, mail systems process the sender and recipient addresses, headers, body, attachments, timestamps, and replies. OnlineCalculator.xyz uses correspondence to respond, investigate a calculator or content issue, handle privacy and security matters, improve the site, keep appropriate records, and protect legal interests.
Do not email passwords, authentication tokens, government identifiers, payment details, health files, account statements, private student records, or confidential employer data. A neutral reproduction is normally sufficient. Correspondence may remain for the time reasonably needed to handle the matter, meet legal obligations, deter abuse, or establish and defend claims, subject to backups and legal holds.
Cookies and similar technologies
OnlineCalculator.xyz application code does not set cookies, advertising identifiers, analytics identifiers, persistent preferences, or browser-stored calculator history. The Cookie Policy provides a category table and explains browser-managed restoration, hosting security, and the disclosures required before any future storage is enabled.
If an essential hosting or security technology sets storage on the public service, the policy will identify its purpose and duration. A non-essential technology will not be enabled until disclosures and legally required choices are in place. The absence of an application cookie does not mean that a browser request or sent email produces no metadata.
Service providers and disclosure
OnlineCalculator.xyz may disclose information it actually holds to providers that host, secure, communicate, or support the service; to professional advisers subject to suitable duties; as part of a lawful organizational transaction; or when reasonably necessary to comply with legal process, enforce terms, investigate misuse, or protect rights and safety.
The operator does not sell calculator entries or directory phrases. Those values are not designed to leave the browser in the first place. Support messages and technical request data are not sold for behavioral advertising. Providers may process data in the United States or other locations used by their infrastructure, where rules can differ. Appropriate transfer safeguards must be used when required.
Retention and security
No server retention period applies to calculator values that are never transmitted. Hosting records and correspondence have separate retention needs. The operator seeks to limit them to configured operational, security, communication, and legal purposes.
Reasonable safeguards can reduce risk but cannot guarantee that every device, network, host, or email system is secure. Visitors should protect their devices, review browser extensions, and avoid unnecessary sensitive content. A result copied to another application is then handled by that destination.
Rights and choices
Privacy rights depend on applicable law and location. They may include access, correction, deletion, restriction, objection, portability, appeal, or a complaint to a supervisory authority. Exceptions and proportionate identity verification can apply. Send a concise request to support@onlinecalculator.xyz and identify the relevant jurisdiction.
If the request concerns a local calculation, the operator may have no record. If it concerns an email, provide enough information to locate the correspondence without supplying excessive identity documents. Browser-managed form history and extensions are controlled through the visitor’s browser or device.
Age, changes, and contact
The service is intended for users aged 16 or older. It has no child profile, account, or personalized advertising. If you believe a person under 16 sent personal information by email, contact the operator without repeating that information unnecessarily.
This policy can change when the product, law, provider settings, or data pathways change. A revised page will state a new effective date, and material notice will be provided where required.
Frequently asked questions
Does the site receive my calculation?
The application calculates locally. Entries are not sent to a remote solver, analytics service, or operator database.
Is my directory phrase stored?
No. It is matched against the local catalog in page memory and excluded from URLs and persistent site storage.
Does support email follow the same local rule?
No. Email is a voluntary network communication handled by mail providers and the operator for the purposes described above.
How do I make a privacy request?
Email support@onlinecalculator.xyz with the request and relevant jurisdiction. Do not attach unnecessary sensitive documents.
