Privacy Policy

Effective date: 1 January 2025  ·  Last updated: 1 January 2025  ·  Applies to: sizeconverter.app

Summary in plain English: SizeConverter does not collect, store or sell any personal information. We do not have accounts, forms or servers that receive your data. The only data stored is your size preferences, saved sizes and recently viewed sizes — and that data stays entirely on your own device. Third-party services (Google AdSense, affiliate partners) may set cookies as described below.

1. Who we are

SizeConverter ("we", "us", "our") operates the website at sizeconverter.app. SizeConverter is a free international clothing size conversion tool.

If you have any questions about this Privacy Policy, you can contact us at: hello@sizeconverter.app

2. What data we collect — and what we do not

Data we do NOT collect

SizeConverter does not operate any servers that receive personal data. We do not collect:

Data stored locally on your device

SizeConverter stores the following data in your browser's localStorage. This data never leaves your device and is never transmitted to us or any third party:

You can delete all of this data at any time by clearing your browser's site data for sizeconverter.app, or by using the delete and clear buttons within the app itself.

3. Cookies

SizeConverter itself does not set any cookies. However, third-party services embedded in this site do set cookies as described below.

Google AdSense cookies

We display advertisements served by Google AdSense. Google uses cookies to serve ads based on your prior visits to this website and other websites on the internet. 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.

You may opt out of personalised advertising by visiting Google Ads Settings or www.aboutads.info. For more information about how Google uses data, see How Google uses data when you use our partners' sites or apps.

Cookies set by Google AdSense may include:

Affiliate partner cookies

SizeConverter includes affiliate links to the following retailers. If you click these links, those retailers may set their own cookies to track purchases for commission purposes:

Clicking an affiliate link does not cost you anything extra. We may earn a small commission if you make a purchase, at no additional cost to you.

4. How we use your data

Because we do not collect personal data, we do not use it for any purpose. The locally stored preferences listed in Section 2 are used solely to improve your experience within the app — for example, remembering your preferred country or saved sizes between visits.

5. Legal basis for processing (GDPR)

This section applies to users in the European Economic Area (EEA), United Kingdom and Switzerland.

Where third-party services (Google AdSense, affiliate partners) process personal data in connection with your visit to sizeconverter.app, the legal basis for that processing is:

You have the right to withdraw consent at any time by opting out of personalised advertising via Google Ads Settings.

6. Your rights

Under GDPR (EU/UK users)

Because SizeConverter holds no personal data on our servers, these rights apply primarily to data processed by third-party services (Google, affiliate partners). To exercise your rights with those services, please contact them directly via the links in Section 3.

Under CCPA (California users)

California residents have the right to know what personal information is collected, used, shared or sold. SizeConverter does not sell personal information. We do not have actual knowledge of selling the personal information of minors under 16 years of age.

To opt out of the sale of personal information by Google, visit Google Ads Settings.

Under PIPEDA (Canadian users)

Canadian users have the right to access personal information held about them and to challenge its accuracy. As SizeConverter holds no personal data, these rights apply to third-party processors listed in Section 3.

Under the Australian Privacy Act

Australian users have rights under the Privacy Act 1988 and the Australian Privacy Principles. These rights apply to personal information held by third-party services associated with this site, as described in Section 3.

7. Data retention

SizeConverter does not retain any personal data on servers. Locally stored preferences (localStorage) are retained on your device until you choose to delete them. You can clear all locally stored data at any time through your browser settings (Settings → Privacy → Clear site data) or through the in-app delete buttons.

8. Children's privacy

SizeConverter does not knowingly collect personal information from children under the age of 13 (or under 16 in the EU). The site does not require registration or any personal information to use. If you are a parent or guardian and believe your child has provided personal information through a third-party service on this site, please contact that service directly.

9. International data transfers

SizeConverter does not transfer personal data internationally because we do not hold personal data. Third-party services such as Google may transfer data internationally in accordance with their own privacy policies and data transfer mechanisms (including Standard Contractual Clauses approved by the European Commission).

10. Security

SizeConverter is served exclusively over HTTPS. All locally stored data remains on your device and is not accessible to us. We take reasonable technical precautions to ensure the security of the site, but no internet transmission is 100% secure.

11. Third-party links

SizeConverter contains links to third-party websites (Amazon, ASOS, Farfetch). This Privacy Policy applies only to sizeconverter.app. We are not responsible for the privacy practices of third-party sites. We encourage you to review the privacy policy of any site you visit.

12. Changes to this Privacy Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of SizeConverter after any changes constitutes your acceptance of the updated policy. We encourage you to review this page periodically.
