Thank you for using the services provided by Helpfeel Inc.

Helpfeel Inc. (Head Office: Kyoto, Japan; Representative Director and CEO: Isshu Rakusai; hereinafter “Helpfeel”) temporarily suspended Gyazo, our image-sharing service, as a precautionary measure to prevent further harm following unauthorized access by a third party and a resulting data breach. We resumed the service on September 27, 2026.

We sincerely apologize to all Gyazo users for the significant concern and prolonged inconvenience caused by the service suspension.

Please note that in this notice, the term “images” refers to all content captured and stored via Gyazo, including screenshots, GIFs, and videos. Unless otherwise stated, all dates and times are in Japan Standard Time (JST).

Service Resumption

Following the discovery of this incident, we blocked the  routes believed to have been used in the unauthorized access and addressed the vulnerability believed to have been the cause of the incident. We also conducted additional security verification across the entire service and implemented necessary countermeasures.

Based on these measures and verification efforts, we resumed Gyazo services on September 27, 2026.

Following the resumption of the service, we will continue our investigation and verification with the involvement of external specialists and implement additional measures as necessary.

Current Image Viewing Status

As part of the service resumption, all images uploaded before the unauthorized access occurred are currently set so that they can only be viewed by their owners. As a result, images that were previously viewable by others are also temporarily inaccessible to anyone other than the owner.

To avoid images becoming accessible to third parties in ways users do not intend, we have decided not to automatically restore all images to their previous status. Instead, users can review the content of their images and choose whether to resume image delivery.

We apologize for the inconvenience and appreciate your understanding.

Resuming Image Delivery

After the service resumes, please review the content of your images and choose either “Resume delivery”  for each image.

Images for which delivery is resumed will return to the visibility settings that were in place before this incident, such as “Only me” or “Anyone with the link.” Before resuming delivery, please carefully review both the content of the image and its visibility setting to help ensure that the image is not unintentionally shared with others.

We apologize for the inconvenience and ask that you review the relevant images before proceeding.

How to Resume Image Delivery

If you wish to resume image delivery, you can do so using one of the following methods:

• Resuming images individually
  Open the relevant image page, review the content, and select “Resume delivery.”
• Resuming multiple images
  Select the images you wish to resume from the image list, then select “Resume delivery” from the side menu.
• Resuming all images at once
  From the “Images with suspended delivery” section of the Settings page, you can resume delivery for all images at once. This option may be useful if you have a large number of images and reviewing them individually would be difficult.
  Please note that when delivery is resumed in bulk, each image will return to the visibility setting that was in place before this incident. If there are images for which you would like to review the visibility setting again, we recommend checking those images individually before resuming delivery.

Even after image delivery has been resumed, you can change the visibility setting through the “Permission” feature and return the image to a state where it is viewable only by you.

Special Measures for Free Plan Users

Under normal circumstances, users on the Free plan cannot access their image history beyond a certain period. As a special measure, however, we are temporarily making all images uploaded before the unauthorized access occurred available for users to review.

This allows Free plan users to review their past images and choose whether to resume delivery or keep delivery suspended.

Request to Change Your Password

To help prevent further harm resulting from this incident, we ask all Gyazo users to change their passwords.

If you use the same or a similar password for Gyazo and any other services, we ask that you also change your passwords for those services.

Please also remain vigilant for any suspicious emails, messages, or other communications related to this incident.

Next Steps

Following the resumption of the service, we will continue our investigation with the involvement of external specialists and proceed with necessary security measures, including reviewing our authentication, authorization, and access controls and strengthening our monitoring and audit processes.

We sincerely apologize once again to all Gyazo users and other stakeholders for the significant concern and inconvenience caused by this incident.
