Privacy Policy

Last updated: 5 November 2026. This policy applies on every SiteCheck host listed at api.sitecheck-api.workers.dev and is part of the Terms of Service.

Who is responsible

SiteCheck, contact sitechecktools@gmail.com. For personal data that you put into a call or ask about, you are the controller and we process it only to answer your call (see section 6 of the Terms).

What we do not do

There are no accounts, no sign-up, no cookies, no tracking pixels and no advertising. We do not sell or rent personal data, and we do not use your calls to build profiles or to train AI models.

What we process

• Request data: the address you call, including query parameters, and the body you send; the HTTP method; headers such as user-agent, referer and the country derived from your IP address. Your IP address is processed by our hosting provider to deliver and protect the service.
• Payment data: the paying wallet address, network, amount and transaction hash. These are recorded on a public blockchain by design.
• Results: answers are kept in short-lived caches so that repeated calls are fast and sources are not overloaded.
• Error reports: technical details of failed calls. Payment headers, signatures and values that look like keys are removed before an error report is sent.

Why

To answer the call you asked for (performance of the contract); to take payment and keep accounting records (legal obligation and legitimate interests); and to keep the service secure, prevent abuse, measure usage and fix errors (legitimate interests).

Who receives data

We share data only with the categories of recipients below, and only as far as each needs it to do its part:

• Service providers that host, secure and monitor the service (hosting, logging, analytics and error monitoring).
• Payment processors and the public blockchains that verify and settle x402 payments.
• Third parties that are necessary to answer a call: the data sources a tool queries (named in each answer) and the technical providers used to reach them or to process the request, including data retrieval and AI processing services. Your query is passed to them only as needed to get the result; their own terms and privacy policies apply.
• Authorities, where the law requires it.

Transfers outside the UK and EEA

Some of these recipients operate outside the UK and the EEA, including in the United States. Where data protection law requires, transfers rely on the safeguards those providers offer, such as standard contractual clauses or the UK international data transfer addendum.

How long

• Request logs: a few days (at most 7).
• Usage analytics: up to about 3 months.
• Error reports: up to 90 days.
• Caches: from minutes up to a day for most tools.
• Payment records: as long as needed for accounting and tax. Blockchain records are permanent and outside our control.

Your rights

Depending on where you are, you can ask for access to, correction or erasure of your personal data, restriction of or objection to its processing, and a copy of it. Because there are no accounts, we usually cannot tell who made a call; to help us find your data, give the wallet address, transaction hash or time of the call. Write to sitechecktools@gmail.com. You may also complain to a data protection authority, such as the UK Information Commissioner's Office or the authority where you live.

Children

SiteCheck is not meant for anyone under 18.

Changes

We may update this policy by publishing a new version at /privacy with a new date.
