GetUtilary operates on a client-first privacy model. Learn how we handle technical data, why calculations execute inside your browser sandbox, and how your privacy rights are safeguarded under GDPR, CCPA, and global data standards.
Welcome to GetUtilary (accessible at https://getutilary.com). We provide a comprehensive suite of online calculators, unit converters, code formatters, random generators, text manipulation instruments, and developer utilities designed for daily professional, academic, and personal use.
Your privacy is a fundamental design principle of our platform, not an afterthought. This Privacy Policy explains how information is collected, processed, and safeguarded when you visit our website, interact with our utilities, or register for an optional account.
The vast majority of utilities on GetUtilary—including mortgage calculators, percentage tools, unit converters, password generators, JSON formatters, regular expression testers, and image resizers—operate 100% inside your local web browser engine using JavaScript, WebAssembly, and HTML5 APIs.
In contrast to conventional cloud-dependent software, your raw input values, confidential financial assumptions, cryptographic seed phrases, source code snippets, and uploaded files are not transmitted to, processed by, or recorded on remote servers. Calculation outputs are generated locally on your physical device.
We strictly adhere to the principle of data minimization: we do not collect, request, or harvest information that is not technically required to deliver the interface.
Depending on your interaction with the platform, the following categories of technical data may be processed:
It is important to understand the technical distinction between HTML5 Local Storage and HTTP Cookies:
We store your visual theme preference (dark/light mode), favorite tools list, and optional local calculation history directly in your browser’s LocalStorage. This data never leaves your device and is never sent to our servers in HTTP headers.
Cookies are small header files. We utilize essential session identifiers for authentication state where needed. For detailed specifics on cookies, please consult our dedicated Cookie Policy.
Using the core utility features on GetUtilary requires no registration. For users who opt into account creation (such as for synchronized favorites or developer API tokens), we store authentication identifiers securely. Passwords are never stored in plaintext and are protected using industry-standard salted hashing and cryptographic safeguards.
To maintain platform performance, optimize calculation speeds, and identify broken utility links, we may collect anonymous, aggregated diagnostic telemetry (such as aggregate page views, browser screen resolutions, and JavaScript runtime errors). These telemetry metrics contain no personally identifiable information (PII) and are not linked to individual user profiles.
To keep our tools free and accessible worldwide, GetUtilary may display third-party advertisements provided by reputable advertising networks, such as Google AdSense.
Our platform may include hyperlinks to external reference websites, authoritative standards organizations (e.g. NIST, ISO, W3C), or open-source documentation. We do not control and are not responsible for the privacy practices, content, or policies of third-party websites. We encourage you to review the privacy notices of any external site you visit.
We employ strict security measures to protect the integrity of the platform:
GetUtilary does not knowingly solicit or collect personal information from children under the age of 13 (or 16 in certain European jurisdictions), in compliance with the Children’s Online Privacy Protection Act (COPPA) and international child privacy frameworks. If we discover that personal information of a child has been inadvertently collected, we will immediately delete that information from our records.
GetUtilary is accessible globally. When technical request logs or account data are processed across cloud content delivery networks, information is safeguarded in accordance with this Privacy Policy and international data protection standards.
If you are a resident of the European Economic Area (EEA) or the United Kingdom, you possess statutory rights under the General Data Protection Regulation (GDPR) and UK Data Protection Act:
To exercise any of these rights, contact our Data Protection Officer at privacy@getutilary.com.
Under the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA), California residents have specific privacy rights:
Because calculation state and preferences reside in your local browser storage, you have immediate, direct control over your data. You may purge all locally stored preferences, tool history, and cached calculations at any time by clearing your browser’s site data for getutilary.com or by clicking "Reset Local Data" in your browser developer settings.
We may update this Privacy Policy from time to time to reflect technological enhancements, new utility capabilities, or evolving legal frameworks. When updates occur, the "Last Modified" date at the top of this document will be updated. We encourage you to review this page periodically.

Traditional online utility websites send your input data to a remote server, process the calculation behind a black box, and return the response across the network. GetUtilary is architected differently:
We believe utility tools should be verifiable and trustworthy. Each calculation model on GetUtilary is implemented using deterministic mathematical algorithms and standard international unit definitions:
Our financial tools use verified fixed-rate loan amortization equations, our unit conversions follow NIST and BIPM standards, and our developer tools strictly comply with RFC specifications. We do not use stochastic AI guesses for mathematical calculations.
Deepen your understanding with our peer-reviewed educational formula guides and real-world calculation tutorials.
