Your own browser does the arithmetic for every Stitchulator calculator, and the numbers you type are never sent to us. A small amount of technical information is transmitted when pages load, and you can limit who receives it.

Who Operates This Site
Stitchulator (stitchulator.com) is an independent website operated by an individual, referred to here as the operator, we, or us. For anything in this policy, write to contact@stitchulator.com. Under the EU and UK GDPR, the operator is the controller of the personal data described below.
What the Calculators Do With Your Numbers
The measurements, gauges, counts, and prices you enter are processed by code running on your own device. They are not transmitted to our server, not stored in your browser after you leave the page, and not combined with anything else. Closing the tab clears them.
Information Collected When You Visit
Like any website, Stitchulator receives some technical information each time a page loads. Depending on which services are active, this can include:
- Server and delivery logs: your IP address, browser type, the page requested, the referring page, and the time of the request, which our hosting provider stores to deliver pages and protect the site from abuse.
- Usage information through Google Analytics: pages viewed, time on page, device and browser type, approximate location at city level, and how you arrived on the site.
- Advertising information through Google AdSense: cookie identifiers, device information, and browsing activity that Google and its partners use to show and measure ads.
- Emails you send us: your address and whatever you choose to write, used only to reply.
We do not ask for accounts, sell products, accept payments, or knowingly collect sensitive information.
Third-Party Services
Google Fonts
The site’s typeface, Inter, loads from Google Fonts. When a page loads, your browser requests the font files from Google’s servers, which receive your IP address and browser information as part of that request. Google describes this processing in its Google Fonts privacy FAQ.
Google Analytics
We use Google Analytics to understand which calculators people choose and which pages to improve. Through Google Analytics, Google sets cookies and processes usage data on its servers. In the EU and UK, we load Analytics only after you consent. You can block it on every site with the Google Analytics opt-out browser add-on.
Google AdSense
Stitchulator is supported by advertising served through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and to other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on those visits.
- You can opt out of personalized advertising in Google’s My Ad Center.
- Many third-party vendors offer an opt-out from personalized advertising at aboutads.info, and in the EU at youronlinechoices.eu.
- Google explains how it uses information from sites that show its ads in How Google uses information from sites or apps that use our services.
Opting out of personalized ads means the ads you see are based on general factors, such as the page you are reading, rather than your browsing history. You will still see ads.
Cookies
We set no cookies of our own and store nothing in your browser. Cookies on this site come from Google Analytics and Google AdSense. You can find them listed by purpose, with ways to control them, in the Cookie Policy.
Legal Bases for Processing (EU and UK)
For visitors in the European Economic Area, the United Kingdom, and Switzerland, we rely on these legal bases:
- Consent for analytics and advertising cookies, and for personalized ads. You give or refuse consent through the consent message shown on your first visit, and you can withdraw it at any time.
- Legitimate interests for delivering pages, loading the site’s typeface, keeping the site secure, and answering emails you send us.
Your Rights in the EU and UK
If the GDPR or UK GDPR applies to you, you have the right to access the personal data we have about you, correct it, delete it, restrict or object to its processing, receive it in a portable format, and withdraw consent at any time without affecting earlier processing. Most data described here is held by Google rather than by us; Google provides its own tools at Google Data & Privacy. To exercise your rights with us, write to contact@stitchulator.com, and we will respond within one month. You may also complain to the data protection authority in the country where you live.
Your Rights in the United States
Residents of California and other US states with consumer privacy laws, including Colorado, Connecticut, Virginia, Utah, and Texas, have rights over their personal information. These include the right to know what is collected, to access and delete it, to correct it, and to opt out of targeted advertising and of the sale or sharing of personal information as those laws define the terms.
- We do not sell personal information for money. Showing personalized ads through Google AdSense may count as sharing for cross-context behavioral advertising under California law.
- To opt out, visit Google’s My Ad Center, the industry opt-out at aboutads.info, or write to contact@stitchulator.com with the subject Do Not Sell or Share.
- We will not treat you differently for exercising any of these rights, and we respond to verifiable requests within 45 days.
How Long Information Is Kept
Calculator inputs are never stored. Our hosting provider retains logs for a short period for security. Google Analytics data is kept for the shortest retention period Google offers, 2 months for detailed event data. Emails are deleted once a conversation ends. Google retains advertising data under its own retention policies.
International Transfers
Google processes data on servers in the United States and elsewhere, and it participates in the EU-US Data Privacy Framework and its UK and Swiss extensions. For transfers those frameworks do not cover, Google relies on the European Commission’s standard contractual clauses.
Children’s Privacy
Stitchulator is a general-audience site and is not directed to children under 13. We do not knowingly collect personal information from children under 13, or under 16 in the EU. If you believe a child has given us personal information, write to contact@stitchulator.com and we will delete it.
Security
We serve the site over an encrypted HTTPS connection and store no accounts, passwords, or calculator data, so very little information is at risk. No method of transmission over the internet is fully secure, however, and we cannot guarantee absolute security.
Changes to This Policy
If we add or change a service that receives your information, we will update this page and the date at the top before the change takes effect.
