What we collect, and what we do not.

Last updated 21 August 2026

Sizio is a small UK product. You paste a listing, we try to recover the garment's measurements, and you can optionally check those against your own. There are no accounts yet, and we do not run a mailing list or advertising pixels.

Who this covers

This notice is for people using the Sizio website at stealth-5fc.pages.dev and the analysis service behind it. Sizio is operated from the United Kingdom.

What we do not collect

We do not ask for your name, email, phone number, or a password. We do not set our own cookies, and we do not use analytics or advertising scripts on this site.

The listing you paste

When you analyse a listing, we fetch that public page so we can read the title, description, photos, and any measurements the seller wrote. We keep a short-lived copy of that result so the same analysis can be shown again if you reload it. That copy is the listing, not a profile of you.

Marketplace pages sometimes include a seller username. If eBay tells us that a seller has closed their account, we delete stored records that mention them.

Country, not your IP

Similar eBay listings are filtered to the site you can actually buy from, which is also the site a UK partner campaign can earn on. To do that, the page reads a country code from Cloudflare (for example GB) and sends that code with the analysis request. We do not send or store your IP address in Sizio.

Cloudflare and Google Cloud, who host the site and API, still see connecting IP addresses in ordinary server logs. That is how any hosted website works. We do not use those logs to build a shopper profile.

Fit-check measurements

If a listing has enough garment evidence, you can type your own measurements for a one-off comparison. Those numbers are sent to our servers for that request only. They are not saved to an account, because we do not have accounts, and they are not written into the listing analysis we store.

Until fit checks run entirely on your device, it would not be true to say your measurements never leave your browser. Your measurements are also stored on this browser only, in local storage, so the next listing is quicker.

Who else sees something

• Cloudflare hosts the website. Google Cloud hosts the API in London (europe-west2).
• Google Cloud Vision may read listing photos when a size tag is likely and the text did not already give us the size. It sees the seller's photos, not photos you upload.
• eBay receives a search for similar garments and the country code, so results match that marketplace. If you follow an eBay or Vinted link, that site's own privacy notice applies.

How long we keep things

Listing analyses sit on the API server while that server is running. They are not copied into a separate long-term database. Fit-check payloads are not stored. Hosting logs follow Cloudflare and Google Cloud's own retention.

Your rights

Under UK GDPR you can ask what we hold, ask for it to be corrected or deleted, and complain to the ICO. Because we do not run accounts, there is usually nothing held against your name. If you send us a listing URL and a time, we can look for that analysis and remove it if it is still there.

Changes

If what we collect changes — for example if sign-up starts, or measurements start being saved on a server — this page will be updated before that becomes the live behaviour.

Questions

There is no public contact email on the site yet. When there is one, it will be on this page. Until then, the honest picture is the one above: we analyse the listing you asked us to analyse, we use a country code to pick an eBay marketplace, and we do not keep a file on you.
