Article 2Information we collect

This site collects the following information.

Enquiries
The company name, name, email address, site URL and enquiry you enter in the contact form. The form is provided on HubSpot (Article 5).
Access logs
The access time, referrer, IP address and browser type recorded automatically by the platform that serves this site, collected for incident response and availability monitoring.

If you only browse, we collect nothing that identifies you. This site uses no analytics tools and no advertising cookies. The free audit uses a single cookie to prevent abusive bulk use (see below).

The free audit (instant report)

  • The URL you enter. This is normally the address of a company website and is not in itself personal information.
  • The report we build from it, and the data behind it, assembled from publicly available information and from the search and AI-answer data we buy.
  • Technical information used to limit how often one requester can run reports. We do not store the address the request came from; we keep only a one-way hash of it, which cannot be reversed.

The free audit uses no cookie. The limit on how often reports can be requested is applied to a one-way hash of the address a request came from, made with a secret key we hold and not reversible; we do not store the address itself. If requests from one address keep arriving in quick succession after its limit is reached, on three consecutive days, we stop accepting requests from that address for 30 days. For that alone we keep a similar hash, with no date in it, only while the decision and the block last (retention is in Article 4).

So that you can open your own reports again, the site keeps their links, the domain and the time, up to twenty, in your browser's own storage (local storage). They are never sent to us, and you can clear them from the page at any time.

The free audit involves no cookie, no account, no login, no email address, no analytics identifier, no third-party script and no identification by combining the characteristics of your device.

Requesting the full report

  • Your name, your company and your work email address. We use them for two purposes and no others: to deliver the report you asked for and contact you about it, and to contact you about our services. We do not provide or sell them to anyone. Inside our company the people who contact you may hold them for that purpose, and a deletion request reaches that copy too. They do not appear in the report itself or in the PDF; they are held separately as the record of your request. You can ask us to stop the contact and to delete them at any time. (Terms terms-v1.1 (2026-09-21).)

Article 3Purposes of use

We use the information we collect only for the following purposes.

  • To answer your enquiry and to contact you about it
  • To send you information about our services (only if you have made an enquiry)
  • To monitor the availability of this site and respond to incidents

We do not use the information for advertising, profiling, sale to third parties or any other secondary purpose.

Article 4Retention period

Enquiries are kept for 3 years from the date we last contacted you and then deleted. You can ask for deletion at any time through the contact point in Article 8. Access logs are deleted automatically after a set period, as configured on the serving platform.

  • The report and the data behind it: kept, without a fixed period, as our own record, inside our environment in the Japan region. We treat it as confidential and show it only to the person who asked for it. We do not publish it, do not list it anywhere, do not allow search engines to index it, and do not provide or sell it to anyone else. Send us the link to the report and we will delete it and confirm when it is done. If you no longer have the link, we will take the request in a way we can verify; we will not tell anyone who cannot show the link whether a report exists for a given domain.
  • The per-domain cache: 24 hours, so that asking twice in one day does not fetch the site twice.
  • The hashes used for rate limiting: only the current day's are kept, and they are deleted at the first request after the day ends. The hash with no date in it, used to decide and enforce a 30-day block on repeated misuse, is deleted at the first request after that decision and block end, which is 33 days at most.
  • Your name, company and email: kept while your request is open and for the contact purpose above. Ask us to stop or to delete them and we do both.
  • What we send outside: we buy search and AI-answer data from DataForSEO OÜ (Estonia). We send them the domain you entered and search terms only; we do not provide them with personal information. Under their own policy they keep API task data for 365 days and publish no procedure for deleting it sooner. So our deletion ends our copy, not theirs.

Article 5External services and transfers to third parties abroad

The contact form uses form functionality provided by HubSpot, Inc. (United States), and what you enter is stored on servers that company operates in the United States. Under Article 28 of the APPI we inform you as follows.

Recipient
HubSpot, Inc.
Country
United States of America
Personal information protection regime
The country has no personal information protection regime recognised as equivalent to Japan's, but the company publishes its arrangements under the EU-US Data Privacy Framework and similar schemes.
Measures taken
The scope of processing is limited under our contract with the company and the data processing terms it publishes.

Please review the above before submitting the form. If you prefer to contact us without the form, use the contact point in Article 8.

Article 6Provision to third parties

We do not provide personal data to third parties without your prior consent, except in the following cases.

  • Where required by law
  • Where necessary to protect a person's life, body or property and obtaining your consent is difficult
  • Where it is necessary to cooperate with a national agency or similar body in carrying out duties prescribed by law, and obtaining consent would be likely to impede those duties

We never sell your information to third parties.

Article 7Requests for disclosure, correction and deletion

We respond without delay, as the law requires, to your requests for notification of the purpose of use, disclosure, correction, addition, deletion, suspension of use, erasure or suspension of provision to third parties of the personal data we hold. Use the contact point in Article 8. We act on the request after confirming your identity.
