Privacy Policy
Last updated: 2026-10-13
NoSignup Diagrams is a free online diagram editor that works without registration. This policy explains what information is processed when you use the site and what choices you have.
Your diagrams stay on your device
There is no account or registration. Your diagrams are edited in your browser and are not uploaded to or stored on our servers. When you save a project, it is downloaded to your own computer as a .zip file; when you open it, your browser reads the file locally. PNG and PDF exports are also created in your browser.
Information stored in your browser
We store only your language preference in your browser's local storage (localStorage) so that the site opens in the language you chose. When you open a project of a different diagram type, it is kept temporarily in session storage (sessionStorage) to pass it to the right editor and is deleted as soon as it is loaded. This information never leaves your device, and you can delete it at any time by clearing your browser data.
Server logs
Like most websites, our hosting server may automatically record technical information such as your IP address, browser type, the pages requested and the time of the request. This data is used only to run the service securely and to diagnose errors, and is not used to identify you.
Advertising and cookies
To keep the service free, we show ads provided by Google AdSense. Google and its partners use cookies and similar technologies to show ads based on your previous visits to this and other websites, to limit how often an ad is shown and to measure ad performance. 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.
Your advertising choices
You can turn off personalised advertising in Google Ads Settings, or opt out of some third-party vendors' use of cookies at www.aboutads.info. You can also block or delete cookies in your browser settings. To learn more, see how Google uses information from sites that use its services.
Consent (EEA, UK and Switzerland)
If you visit from the European Economic Area, the United Kingdom or Switzerland, personalised ads and cookies are used only after you give your consent through the consent message shown on the site. You can change or withdraw your consent at any time using the privacy settings link in that message.
Legal basis
Where data protection laws such as the GDPR or the Turkish Personal Data Protection Law (KVKK) apply, server logs are processed on the basis of our legitimate interest in operating a secure service, and advertising cookies on the basis of your consent.
Your rights
Depending on where you live, you may have the right to access, correct or delete your personal data, to object to or restrict its processing, and to lodge a complaint with your data protection authority. Because we do not store your diagrams or create user accounts, we usually hold no data that can be linked to you; requests about advertising data can also be made directly to Google.
Children
The site is not directed at children under 13 (or under the minimum age required in your country), and we do not knowingly collect their personal data.
Changes to this policy
We may update this policy from time to time. The date at the top of the page shows when it was last changed.
