Privacy Policy
Last updated: 2026-10-27
This policy explains what happens to your information when you use Tire Size Comparison at https://tire-size-comparison.pages.dev (the "Site"). The Site is operated by an independent developer ("we", "us").
The short version
- Tire sizes you type stay in your browser. They are used only to calculate and draw the result on your screen. They are not sent to us or to anyone else.
- No accounts, no email, no payments. You don't sign up, and we don't ask for your name or email address.
- We use Google Analytics to count visits and see which pages and tools are used. Analytics events never include the sizes you type.
- We don't sell or share your personal information for advertising.
- Ads may be added later. If we add advertising or affiliate links, we will update this policy and the cookie choice before they go live.
1. What stays on your device
The tire sizes you type are held in the page's memory only. They are not saved and are not sent over the network. The only thing the Site writes to your browser's local storage is your cookie choice ("granted" or "denied", see section 3).
2. Information we collect
| What | How | Why |
|---|---|---|
| Usage data: pages viewed; that a tool was used or a result was shown (never the sizes); approximate location (country or city); device and browser type; referring site | Google Analytics 4 cookies and scripts | To understand which pages and tools are used and to improve the Site |
| Technical data: IP address, browser user agent, time of request | Sent automatically by your browser when it loads our pages | To deliver the Site and keep it secure |
We don't create accounts and we don't collect payment information. The Site has no paid features.
3. Analytics and cookies
We use Google Analytics cookies only:
| Cookie | Set by | Purpose | Expires |
|---|---|---|---|
_ga | Google Analytics | Tells visitors apart | Up to 2 years |
_ga_<ID> | Google Analytics | Keeps session state | Up to 2 years |
If you visit from the European Economic Area, the United Kingdom, or Switzerland, these cookies are off until you click "Accept" in our cookie banner. Before you choose, Google Analytics may still receive basic signals without cookies (for example, that a page was loaded), as part of Google's Consent Mode. Elsewhere they are on by default, and you can click "Reject" to turn them off. You can change your choice at any time with the "Cookie settings" link at the bottom of every page. If you reject, we stop sending analytics from your browser and delete the Google Analytics cookies we can reach.
We have turned off Google signals and ad personalization in Google Analytics, and we don't link Google Analytics to any advertising account. We don't currently use advertising cookies or ad pixels.
Wherever you are, you can also block or delete cookies in your browser, or install Google's opt-out add-on: https://tools.google.com/dlpage/gaoptout
Do Not Track: The Site doesn't change its behavior based on "Do Not Track" signals. Because we don't sell or share personal information for targeted advertising, there is nothing of that kind to opt out of.
4. Who processes data for us
| Provider | Role | Data | Privacy policy |
|---|---|---|---|
| Cloudflare, Inc. | Website hosting | IP address, request data | https://www.cloudflare.com/privacypolicy/ |
| Google LLC (Google Analytics) | Usage statistics | Cookie ID, usage data, approximate location | https://policies.google.com/privacy |
Neither provider receives the tire sizes you type.
5. How long we keep data
| Data | Retention |
|---|---|
| Tire sizes you type | Never stored; discarded when you close or reload the tab |
| Cookie choice | On your device until you clear it |
| Google Analytics data | Kept for the shortest retention period Google offers for our property (2 months), then deleted automatically by Google |
| Technical request data | Kept by Cloudflare under its own policy; we don't keep copies |
6. Legal bases (EEA, UK, and Swiss visitors)
- Showing your result: necessary to provide the tool you asked for. We never receive the data.
- Analytics cookies: your consent, given through the cookie banner. You can withdraw it at any time with "Cookie settings".
- Technical request data: our legitimate interest in delivering the Site and keeping it secure.
7. Your rights
Depending on where you live (for example in the EEA, the UK, California, Washington, or another US state with a privacy law), you may have the right to:
- access, correct, or delete your personal information;
- object to or restrict processing;
- withdraw consent;
- receive a copy of your data;
- opt out of the sale or sharing of personal information. We don't sell or share it.
To make a request, email federicoardorussoa50970@gmail.com. We won't treat you differently for using these rights. For analytics data, clearing your cookies breaks the link between you and past usage data.
If you're in the EEA or the UK, you can also complain to your local data protection authority.
8. International transfers
Google and Cloudflare may process technical and analytics data in the United States and other countries. Where required, they rely on legal transfer mechanisms such as the EU Standard Contractual Clauses or the EU-US Data Privacy Framework.
9. Children
The Site is not directed to children under 13, and we don't knowingly collect personal information from them. If you believe a child under 13 has used the Site and you want analytics data removed, contact us.
10. Security
The Site is served over HTTPS. The sizes you type are never sent over the network.
11. Changes
If we add accounts, saving, payments, email, advertising or affiliate links, we will update this policy before the change takes effect and ask for your consent where required. The "Last updated" date at the top shows the latest version.
