Who is responsible
The Percentage Calculator is operated by Nikolay Iliev, based in Bulgaria. For questions about information handled by the website, contact info@percentagecalculators.app.
This notice describes the calculator website you are visiting. Hosting platforms and app stores also process information under their own privacy notices, as described below.
Your online calculations
The four online calculators perform the arithmetic in your browser. The calculator code does not send your input numbers in a calculation request or upload your results to a database.
The website does not create a calculation history or a calculator account for you. The current calculator pages do not save your input values in local storage.
When you choose Copy, the result is written to your device’s clipboard. The calculator does not read other clipboard contents. Your device or clipboard software can retain copied text according to its own settings.
When you contact us
If you email support, the recipient receives the email address, message and any other information you choose to send. This is used to answer the request, investigate a reported issue and handle related follow-up.
Correspondence may be handled through email service providers. For processing within our responsibility, the basis is our legitimate interest in responding to enquiries and maintaining the service, or a legal obligation where one applies.
Technical access and hosting
Hosting and access services receive technical request information needed to deliver pages and maintain security. This can include an IP address, browser information, requested page, request time and technical error information. A page address or referrer can also be included in an ordinary web request.
We use website infrastructure for delivery, reliability and protection against abuse. Where we process information for these purposes, we rely on our legitimate interests in operating and securing the service.
Cookies and browser storage
This website uses Google Analytics 4 to understand visits and interactions with its pages. Google Analytics can use cookies and browser identifiers and receive information such as the page address, referring site and browser or device details.
The calculator code does not add the numbers you enter or calculation results to Google Analytics events. The website does not include advertising pixels or an advertising system. Fonts and product images are served with the website.
See how Google uses information from sites that use its services. Google also provides an Analytics opt-out browser add-on.
Hosting services may use technical cookies or other storage for access and security. You can manage cookies and site storage through your browser settings. Restricting essential storage can affect website access.
The mobile app has separate advertising and analytics practices, described in its policy and store disclosures.
Recipients, retention and transfers
Information needed to operate the website or respond to messages may be handled by hosting, access and email service providers. Information may also be disclosed when required by law or when necessary to address misuse or establish or defend legal claims.
Calculator inputs are not retained in a website results database. Support correspondence is kept for the time needed to resolve the enquiry and related follow-up, and for any applicable legal requirement or necessary legal claim. Technical records held by infrastructure providers follow their own retention policies.
Providers can process information in countries outside your own. Their policies describe their locations and transfer arrangements. Contact us if you need help identifying which service handles information connected to your enquiry.
Your privacy rights
Depending on the law that applies, you may ask to access or correct personal information, request deletion or restriction, object to processing, or request portability where its conditions are met. If processing relies on consent, you can withdraw that consent without affecting earlier lawful processing.
Send a request to info@percentagecalculators.app. We may need information to locate the relevant correspondence and verify the request. We respond within the time limits required by applicable law.
You may complain to your local data protection authority. In Bulgaria, this is the Commission for Personal Data Protection. The European Commission explains individual rights under the GDPR.
The website calculators do not make automated decisions about eligibility, credit, employment or other matters with legal or similarly significant effects.
Mobile app privacy is separate
The mobile app’s free version includes ads. Its data handling can include advertising and analytics services; it should not be inferred from the website’s local calculation behaviour.
Review the privacy information in the App Store listing and the Data safety information in the Google Play listing, together with the app-specific policy and terms. Practices and permissions can differ by platform and version.
Premium removes ads. That description does not by itself mean that all diagnostic or analytics processing stops. For questions about the mobile app’s data practices, contact support.
General audience and policy updates
The calculators are intended for a general audience. A calculation does not ask for a child’s name, school, age or contact details. A parent or guardian can contact us about personal information sent in a support message.
Changes to website features or data handling will be reflected in this notice. The date at the top identifies the current version. Questions can be sent to info@percentagecalculators.app.
