Privacy Policy

Last updated: September 21, 2026

Information We Collect

OnlineToolHubs is designed with privacy in mind. Most of our tools run entirely in your web browser, meaning your data stays on your device and is never transmitted to our servers.

We do not require registration or collect personal information such as names, email addresses, or phone numbers to use our tools.

Data Processing

Client-Side Tools

Calculators, converters, text tools, and AI-powered tools process data entirely within your browser. No data is sent to our servers or any third-party servers.

API-Powered Tools

Some tools (weather, currency conversion, country lookup) send queries to third-party public APIs to fetch real-time data. Only the minimum necessary information (such as a city name or currency code) is transmitted. We do not log these queries.

AI-Powered Tools

Our AI tools use machine learning models that download to and run in your browser. Your text is processed locally and never leaves your device.

Cookies and Local Storage

We use browser localStorage to save your tool preferences and recent inputs for convenience. This data is stored only on your device and is not transmitted to us.

Third-Party Advertising

We use Google AdSense to display advertisements on our site. Google may use cookies to serve ads based on your prior visits to our website or other websites. You can opt out of personalized advertising by visiting Google Ads Settings.

Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the Internet. For more information, please review Google's advertising policies.

Consent, and visitors in the EEA, UK and Switzerland

Advertising on this site is served by Google. For visitors in the European Economic Area, the United Kingdom and Switzerland, Google requires that consent for personalized advertising and for the cookies that support it is collected through a consent management platform certified by Google, and it presents that consent message itself before serving personalized ads to those visitors.

Whatever your region, you can control or disable ad personalization directly through Google Ads Settings. Turning personalization off does not remove advertising from the site; it means the ads you see are no longer based on a profile of your activity. You can also block or delete cookies in your browser settings, which does not affect any of the tools, since none of them require cookies to work.

Your rights

The browser-based tools on this site process your data entirely on your own device and transmit nothing, so for those there is no data held by us to access, correct or delete.

Where advertising or analytics cookies have been set, and depending on where you live, you may have the right to access the data held about you, to have it corrected or deleted, to object to or restrict its processing, to withdraw consent, and to data portability. Those rights are exercised against the party holding the data — for advertising cookies that is primarily Google, whose controls are linked above. For anything we hold, email contact@onlinetoolhubs.com.

California residents

We do not sell personal information for money. Under the CCPA and CPRA, the use of advertising cookies to serve interest-based advertising may be treated as a “sale” or “share” of personal information. You can opt out of personalized advertising through Google Ads Settings, or by using a Global Privacy Control signal in your browser, which this site honors. California residents also have the right to know what personal information is collected, to request deletion, and not to be discriminated against for exercising these rights.

Third-Party APIs

Some tools require a live network request to answer at all. When you use one, your query — a city name, a domain, a postal code — is sent to the service named below, which has its own privacy policy and will see your IP address. Tools not listed here send nothing. The list below covers every external service called by a published tool:

  • Open-Meteo — weather, air quality, UV index, elevation and place-name geocoding
  • ExchangeRate (open.er-api.com) — currency rates
  • CoinGecko — cryptocurrency prices and market data
  • Cloudflare DNS (cloudflare-dns.com) — DNS record lookups
  • Zippopotam.us — postal code lookups
  • Open Library — ISBN book lookups
  • dictionaryapi.dev — dictionary definitions
  • Datamuse — rhymes and synonyms
  • Agify, Genderize and Nationalize — name-based demographic estimates
  • Open Trivia Database — trivia questions
  • JokeAPI — jokes

We do not send your IP address, browsing history or any identifier of our own to these services. They receive only the query you typed, plus whatever your browser discloses in making any request.

Analytics

We may use aggregated, anonymised analytics to understand which tools are used and to fix problems. No personally identifiable information is collected through analytics, and we do not build profiles of individual visitors.

Data retention

We operate no database and no user accounts, and the site is served as static files. We do not retain the contents of anything you type into a tool, because for the browser-based tools we never receive it and for the API-backed tools we do not log it. Cookies set by Google for advertising are retained according to Google's own policies.

Children's Privacy

Our tools are general-purpose and not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we will act on it.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.
