Privacy Policy

Last updated: October 18, 2026

Overview

LilUtils is a privacy-conscious, browser-native utility platform offering free developer tools, converters, design utilities, mini arcade browser games, and live open-data exploration tools. We design our software so that everyday tools run entirely on your own device. We do not require accounts, logins, or server-side file uploads for our utilities. This Privacy Policy details what information is collected, how external services operate, how live open-data queries work, and how you control your privacy choices.

Zero Server-Side Storage of Tool Data

The core principle of LilUtils is client-side execution. When you format JSON, generate a QR code, decode a JWT, hash a password, inspect an SVG, calculate timestamps, or play arcade games, the computations are performed purely within your browser's JavaScript engine and Web Workers.

  • No File or Text Uploads: Your input text, code snippets, cryptographic keys, and uploaded files are never sent to LilUtils servers.
  • No Server Logs of Content: We maintain no backend database or logging pipeline that captures your inputs, tool payloads, or results.
  • Local Persistence Only: For your convenience, non-sensitive form inputs (such as your chosen options or active theme) may be remembered in your browser's local storage. This data never leaves your device and can be cleared at any time.

Live Public Data Tools & External APIs (Explore Category)

Tools within our Explore category (such as the Earthquake Monitor, Global Weather Forecast, ISS Orbit Tracker, Natural Events Tracker, PubChem Compound Explorer, and openFDA Drug Search) connect directly from your browser to reputable public open-data endpoints (including the USGS, NASA, Open-Meteo, MET Norway, the US National Library of Medicine, the US FDA, and the World Bank).

  • Direct Client-to-API Requests: Requests originate directly from your web browser to the public API endpoints. LilUtils does not act as a proxy server and does not intercept or record your search parameters.
  • No API Keys Required: All public data tools operate strictly on open, unauthenticated public domain or open-access APIs.
  • Client-Side Rate-Limit Caching: To protect public infrastructure from rate limits, responses may be cached ephemerally in your browser's sessionStorage or localStorage with short Time-To-Live (TTL) expiries. These caches are strictly local to your browser.

Analytics & Google Analytics 4 (GA4)

We use Google Analytics 4 (GA4, Measurement ID G-080GKP3QPM) to understand aggregate site traffic, popular tools, navigation flows, and technical reliability. GA4 collects high-level event telemetry such as page views, search interactions, tool launches, and theme toggles.

  • Google Consent Mode v2: We have implemented Google Consent Mode v2. By default, signals for analytics_storage, ad_storage, ad_user_data, and ad_personalization are denied until appropriate consent or regional configuration applies.
  • No Tool Payload Tracking: We strictly prohibit sending sensitive user text, code, passwords, or personal files as analytics parameters.
  • IP Anonymization: Google Analytics 4 automatically discards individual IP addresses during processing.

Advertising & Google AdSense

To keep LilUtils 100% free for everyone without paywalls or subscriptions, we display advertisements served by Google AdSense and its certified advertising partners.

  • Third-Party Cookies & Ad Technology: Third-party vendors, including Google, use cookies, web beacons, and device identifiers to serve ads based on prior visits to LilUtils or other sites across the internet.
  • Personalized vs. Contextual Ads: In jurisdictions where consent is given, Google may serve personalized advertisements tailored to your interests. In the absence of consent or where restricted by law, only contextual or non-personalized ads are requested.
  • Ad Personalization Opt-Out: You can manage or disable personalized advertising at any time by visitingGoogle Ads Settings orAboutAds Choices.
  • Google Partner Data Usage: For details on how Google uses data collected through partner sites, visitHow Google uses information from sites or apps that use our services.

Consent Requirements (EEA, UK, Switzerland & US States)

In compliance with the General Data Protection Regulation (GDPR), UK GDPR, and Google's EU User Consent Policy, visitors from the European Economic Area (EEA), the United Kingdom, and Switzerland are presented with consent controls. Non-essential cookies and personalized advertising remain blocked until affirmative consent is provided. We also respect Global Privacy Control (GPC) signals and opt-out preferences under applicable US state privacy laws.

Affiliate Links

Some outbound resources or tutorial references may contain affiliate links. These links include standard tracking parameters (such as utm_source, utm_medium, and utm_campaign). If you make a purchase through an affiliate link, LilUtils may earn a commission at no extra cost to you. Editorial recommendations remain strictly independent of affiliate arrangements.

Your Choices & Privacy Controls

  • Privacy Choices Modal: You can open our on-site consent manager at any time via the "Privacy Choices" link in the footer to review, update, or revoke consent for analytics and advertising.
  • Browser Storage Settings: You can clear your browser's cookies, local storage, and session cache at any time to remove saved preferences.
  • Ad Blockers & Private Browsing: LilUtils is engineered to remain functional even if you use ad-blocking extensions, privacy-centric browsers, or strict tracking prevention.

Children’s Privacy

LilUtils is designed for general audiences and developers. We do not knowingly collect personal information from children under the age of 13.

Policy Updates

We may update this Privacy Policy from time to time to reflect site improvements, new tools, and evolving legal standards. The "Last updated" date at the top indicates when the latest revision took effect.
