Privacy policy

As a provider of products and services for AI-driven software development, Makit 株式会社 (MAKIT INC., "we") complies with the Act on the Protection of Personal Information of Japan ("APPI") and related laws and guidelines, and handles personal information as set out below.

This is a reference translation. If it differs from the Japanese version, the Japanese version prevails.

1. Business operator

Makit 株式会社 (MAKIT INC.), Representative Director Ritsu Nakamoto / Address: 12F Yokohama Blue Avenue, 4-4-2 Minatomirai, Nishi-ku, Yokohama, Kanagawa 220-0012, Japan

2. Information collected

(1) Information you enter when making an enquiry or requesting materials: company, department, title, name, email address, telephone number and enquiry content. (2) Information provided in connection with a contract and our services: the names and contact details of your staff, and personal information contained in the data we process on your behalf (source code, design documents, etc.). (3) Information recorded automatically when you browse this site: access logs such as IP address, date and time, pages viewed and browser type, and cookies.

3. How we collect it

Lawfully and fairly, through the forms on this site, email, exchange of business cards, contract procedures, data you provide to us in the course of contracted work, and automatic recording by this site's servers.

4. Purposes of use

(1) Replying to enquiries and sending materials. (2) Preparing estimates, concluding and performing contracts, and providing, maintaining and supporting our services. (3) Informing you about our products, services and events (we stop on request). (4) Operating this site and our services securely, preventing unauthorised access and handling incidents. (5) Statistical analysis to improve our services (performed on data processed so that individuals cannot be identified). (6) Responding as required by law. We obtain your consent in advance before using personal information for any other purpose.

5. Provision to third parties

We do not provide personal data to third parties without your prior consent, except where required by law, where necessary to protect a person's life, body or property and it is difficult to obtain consent, or in the other cases listed in Article 27(1) of the APPI. Provision in connection with outsourcing, business succession or joint use does not constitute provision to a third party under Article 27(5).

6. Outsourcing

To the extent necessary to achieve the purposes of use, we may outsource all or part of the handling of personal data to external providers (cloud services, email delivery, providers of generative AI (large language model) APIs, etc.). We select providers that handle personal data appropriately, require security measures by contract, and supervise them as necessary and appropriate.

7. Provision to third parties in foreign countries

Personal data collected through enquiries on this site is stored and processed on servers in Japan (Tokyo), and is not currently provided to third parties in foreign countries. If in future we provide personal data to a third party in a foreign country, for example by outsourcing email delivery to a provider outside Japan, we will publish the recipient's country in this policy and, in accordance with Article 28 of the APPI, either obtain your consent after providing the prescribed information or provide the data only to recipients that maintain systems meeting the standards under Article 28(1), taking the measures required under Article 28(3). Where data is processed in contracted work (including processing by generative AI), the processing location is set out in the contract with the customer.

8. AI processing

Our products and services process data you entrust to us (source code, design documents, etc., which may contain personal information) using generative AI. (1) As a rule, we do not use data you entrust to us to train AI models. Where your contract provides otherwise, the contract prevails. (2) As a rule, we choose generative AI APIs offered on terms under which input data is not used for model training, and we review the providers' terms regularly. (3) Entrusted data is processed only within the scope of the work set out in the contract, and is returned or deleted after the work ends in accordance with the contract.

9. Retention period

We retain personal data for as long as necessary to achieve the purposes of use or as required by law or contract, and endeavour to delete personal data without delay once it is no longer needed.

10. Security measures

To prevent leakage, loss or damage of personal data, we take the following measures. (1) Organisational: appointing a person responsible, establishing handling rules, and preparing a response system for incidents. (2) Personnel: confidentiality arrangements with staff and regular training. (3) Physical: controlling areas where personal data is handled and preventing theft or loss of devices and media. (4) Technical: access control and authentication, encryption in transit and at rest, logging and monitoring of access, and prevention of unauthorised access. (5) Understanding the external environment: personal data is stored and processed on servers in Japan (Tokyo). If it comes to be handled in a foreign country, we will take measures based on an understanding of that country's personal information protection system.

11. Matters concerning retained personal data

Our name, address and representative are as stated in "1. Business operator"; the purposes of use in "4. Purposes of use"; the security measures in "10. Security measures"; the procedure for requests in "12. Requests for disclosure, etc."; and where to make complaints in "13. Contact point".

When you or your agent request notification of the purposes of use, disclosure (including records of provision to third parties), correction, addition or deletion, suspension of use or erasure, or suspension of provision to third parties of retained personal data, we will respond without delay in accordance with the law after verifying your identity. Please send requests by email to business@makit.ai; we will explain the procedure. If a fee applies, we will inform you of the amount in advance.
