Privacy policy — 100buy.best

1. What this policy covers

This policy describes how 100buy.best handles information when you visit. It covers the site itself, the tools it provides and the links it carries to other sites. It does not cover what happens on those other sites, and it cannot, because we have no control over them.

2. What we collect

Nothing that identifies you. This site is a set of static pages. It has no accounts, no sign-in, no comment system, no newsletter form and no contact form that submits to a server. There is no database behind it and no application server that could write to one.

The tools on this site run entirely in your browser. The values you type into a calculator are used to compute the result on your own device and are then discarded when you close or reload the page. They are not transmitted anywhere, and there is no analytics script watching what you enter.

3. What we do not collect

• No name, email address or postal address, because there is no field to enter them into.
• No payment information of any kind. This site does not sell anything and cannot take a payment.
• No order or parcel data. We do not handle orders.
• No account identifiers, because there are no accounts.
• No location data beyond what any web server necessarily receives to deliver a page.

4. Cookies and local storage

This site sets no cookies of its own and writes nothing to local storage or session storage. Some hand-offs between the tools travel in the page address rather than in storage, which means they are visible in your browser history and in any link you copy — that is deliberate, because it makes the hand-off inspectable and shareable, and it leaves nothing behind on your device.

5. Hosting and server logs

The site is served through a content delivery network. Like any host, it necessarily processes the request data needed to return a page: an IP address, a user agent string, the requested address and a timestamp. That processing happens at the network edge for security and reliability purposes, including protection against abusive traffic. We do not combine it with anything else, because there is nothing else to combine it with.

6. Outbound links

Pages on this site link to kabosheet.com, a catalogue of product entries. When you follow one of those links you leave this site and arrive at a different one, which has its own privacy policy and its own data practices. Those practices are outside our control and outside this policy.

Outbound links carry a short parameter identifying this site as the source. It contains no information about you: it is the same string for every visitor and every click. It exists so that the catalogue can tell how much traffic arrives from here, and it is described in plain terms on the provenance page rather than left unexplained.

7. Analytics

This site does not load a third-party analytics script and does not run a self-hosted one either. Aggregate traffic figures, where they exist, come from the hosting network’s own request counts rather than from a tracking script in the page. If that changes, this section will say so, the effective date above will move, and the change will be recorded on the revisions page.

8. Children

This site is not directed at children and does not knowingly collect anything from anyone, including children, because it does not collect personal information at all.

9. Your rights and how to exercise them

Data protection rules in various jurisdictions give you rights of access, correction, deletion, restriction and portability over personal data held about you. Since this site holds no personal data about you, there is nothing for us to retrieve, correct or delete. If you believe otherwise, write to privacy@100buy.best with what you think is held and why, and we will investigate and answer.

10. Changes to this policy

Material changes will be published on this page with a new effective date, and recorded on the revisions page. Continuing to use the site after a change means the revised policy applies. We do not notify by email, because we do not have your email address.

11. Contact

Privacy questions: privacy@100buy.best. Corrections to any figure on the site: corrections@100buy.best, or see the errata page. Method and source labels are explained on the standards page.
