Privacy policy

Last updated: 2026-10-29

This policy explains what data AI Stack Wise collects when you use the site, why, and what choices you have.

In short:

  • There are no user accounts. You can use every page, calculator and tool without signing up.
  • Our analytics are cookieless (Cloudflare Web Analytics). We do not use Google Analytics.
  • The site shows Google AdSense ads, which can use cookies. Where required, we ask for your consent first.
  • Text you enter in our browser tools (token counter, word counter, AI text cleaner, Markdown converter) is processed on your device.

Who we are

AI Stack Wise is a website that tracks and compares the cost of AI tools and AI APIs. In this policy, “AI Stack Wise”, “we” and “us” mean the operator of this website.

Data collected when you visit

The site is hosted and delivered by Cloudflare. To serve pages and protect the site from abuse, Cloudflare processes standard request data, such as your IP address, browser and device type, the page you requested (including any calculator settings in the page address), the referring page and the time of the request. This is needed to run the site and keep it secure. See Cloudflare’s privacy policy.

We do not use this data to identify you.

Analytics

We use Cloudflare Web Analytics to understand which pages and tools are used. It is cookieless: it does not set cookies on your device and does not build a profile of you across websites. It gives us aggregated figures such as page views, referrers, countries and device types.

We do not use Google Analytics (GA4) at launch. If that changes, we will update this policy first.

Cookies and advertising

AI Stack Wise uses Google AdSense to show ads.

  • Third-party vendors, including Google, use cookies to serve ads based on your previous visits to this website or other websites.
  • Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.
  • You can opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalised advertising by visiting www.aboutads.info.
  • To learn more, see How Google uses information from sites or apps that use its services.

Even non-personalised ads may use cookies or similar technologies for things like frequency capping, aggregated ad reporting and fraud prevention.

We do not work with ad networks other than Google.

Cookies used on this site

Purpose Set by When
Remember your privacy choices Google (consent platform) When you make a choice in the consent message
Advertising, including personalised ads Google and its ad partners Where consent is required, only if you agree; elsewhere according to your choices and Google’s settings

Cloudflare Web Analytics and our browser tools do not set cookies. You can also block or delete cookies in your browser settings; the site still works without them.

We use Google Privacy & Messaging, Google’s consent management platform, to ask for and record your choices.

  • EEA, UK and Switzerland: you see a consent message that uses the IAB Transparency & Consent Framework (TCF). You can accept, reject or choose which purposes and vendors to allow.
  • Google Consent Mode (advanced): the site uses Google Consent Mode in its advanced setup. This means Google’s tags load on the page, and until you agree, or if you decline, they do not set advertising cookies. In that state they may still send limited, cookieless signals to Google, as described in Google’s Consent Mode documentation. If you decline, you may still see ads, but they are non-personalised or limited.
  • United States: visitors in US states with privacy laws see a message that lets them opt out of the “sale” or “sharing” of personal information for targeted advertising.
  • Global Privacy Control (GPC): if your browser sends a GPC signal, we honour it as a request to opt out of sale or sharing for targeted advertising.
  • Change your mind at any time: use the “Privacy settings” link in the footer of every page to review or withdraw your choices.

Browser tools

Our free tools (token counter, word counter, AI text cleaner and Markdown to text) run in your browser. The text you enter is not sent to our servers.

Calculator and quiz settings (for example the plans, seats, token counts or quiz answers reflected in the page address) can appear in the page URL so you can share a result. Like any page address, these can appear in Cloudflare request data and in aggregated analytics. Please do not enter personal information into tool or calculator fields.

Who data is shared with

We do not sell personal data for money. Data is shared only with the services that run the site:

  • Cloudflare: hosting, content delivery, security and cookieless analytics.
  • Google: AdSense ads and the Privacy & Messaging consent platform.

These providers may process data outside your country, including in the United States. We may also disclose data if the law requires it.

How long data is kept

  • Cloudflare request data and analytics: according to Cloudflare’s own retention settings.
  • Advertising data: according to Google’s policies.
  • Your consent choice: stored in your browser until it expires or you clear it.

Your rights

Depending on where you live, you may have rights over your personal data. These can include the right to access it, correct it, delete it, object to or restrict how it is used, and withdraw consent at any time. In some US states you may also have the right to opt out of the “sale” or “sharing” of personal information for targeted advertising, which you can do through “Privacy settings” or by using Global Privacy Control. You may also have the right to complain to your local data protection authority.

Because AI Stack Wise has no accounts, we usually hold very little data that can be linked to you.

Children

AI Stack Wise is meant for adults and businesses comparing AI tools. It is not directed at children, and we do not knowingly collect personal data from children.

Changes to this policy

When this policy changes, we update the “Last updated” date at the top. If we add a new analytics or advertising partner, we will update this policy before it goes live.
