The rules for using MasterShot. Please read them before you start.

Last updated: November 10, 2026

1. About these terms

  1. These terms set the conditions for using the MasterShot (the “Service”) that Optlynx Co., Ltd. (“Optlynx”) offers on MasterShot.
  2. By signing up for the Service, you (the “User”) agree to these terms.
  3. The Service is for people living in Japan. Individuals are welcome.

2. Definitions

  • "Photos": the photo files the User uploads to the Service, and the re-shot versions the Service makes from them
  • "Requests": what the User types in the chat to ask for a different result (such as "scarier")
  • "Taste records": records of which version (Low or Max) the User picked and what Requests they made

3. Signing up

  1. The Service becomes available when the User has confirmed their email address and agreed to these Terms.
  2. One account is for one person. Login details may not be lent to anyone else.
  3. Optlynx may refuse a sign-up with false details, or from anyone who has broken these Terms before.

4. Fees

  1. The Service is free for now. If fees are introduced, we will give at least 30 days' notice, and only Users who sign up for a paid plan will be charged.
  2. Internet connection charges are borne by the User.

5. What the Service provides

  1. The User uploads a phone photo, and AI produces the photo a professional photographer would have taken at the same moment. Two versions are made, a restrained "Low" and a "Max" with richer light and mood, and the User picks one.
  2. Faces are never changed, nothing that was not there is added, and lettering is not altered. The User accepts that Optlynx works within these rules.
  3. Optlynx may limit the number of re-shoots. Any limit is shown in the member area.
  4. Storage is limited to 2GB per person. Photos are deleted automatically 30 days after they were last used. Save any result you want to keep.

6. Rights to your photos

  1. The rights to the Photos belong to the User. Optlynx takes no rights to them. The User may use the re-shot versions freely.
  2. Optlynx handles Photos only to re-shoot and inspect them in the Service. For this, the photo and the Request are sent to an AI company (Google), with settings under which the content is not used for AI training.
  3. Optlynx does not view, use or publish the User's Photos for any other purpose.

7. Prohibited uses

  • Uploading photos that infringe the rights of others (copyright, portrait rights, privacy, etc.)
  • Re-shooting photos in order to deceive, or presenting a re-shot photo as a genuine record
  • Any purpose that breaks the law or public order
  • Putting heavy load on the Service, extracting data by any means other than those provided, or reverse engineering it
  • Signing up with someone else's email address, or letting others use your login

8. Deleting your account

  1. The User can delete their account at any time from the settings screen.
  2. Deleting the account permanently deletes the account information, all Photos and the Taste records.

9. Cancellation by Optlynx

If the User breaks these Terms, or is found to be involved with antisocial forces, Optlynx may cancel the account immediately after notice.

10. No warranty

Re-shooting is done automatically by AI. Optlynx does not guarantee that the result matches what the User had in mind, that the AI always works correctly, or that every photo can be handled. Always keep the original photo on your phone.

11. Limitation of liability

  1. Optlynx is not liable for any loss arising from your use of, or inability to use, the Service, including loss caused by deleted photos, except in cases of willful misconduct or gross negligence.
  2. Where Optlynx is liable, because the Service is free, liability is limited to ordinary and direct loss and capped at 10,000 yen.

12. Changes to and end of the Service

Optlynx may change or end the Service. If we end it, we will tell you at least 30 days in advance.

13. Organized crime

You confirm that you are not, and have no ties with, organized crime groups.

14. Changes to these terms

Optlynx may change these terms. We will post the changes and their effective date on MasterShot, or notify you, before they take effect. If you keep using the Service after that date, you agree to the changes.

15. Governing law and court

These terms are governed by the laws of Japan. The Osaka District Court has exclusive jurisdiction in the first instance over any dispute about the Service.

This English version is provided for convenience. If it differs from the Japanese version, the Japanese version prevails.
