Privacy Policy

Effective date: November 14, 2026 (previous version: November 10, 2026) / Operator: YS Studio (Japan) / Contact: ys_studio_info@sketch-surgeon.com

YS Studio ("we", "us" or "our") provides the smartphone and tablet app "FamShare" and its web version for browsers at https://famshare.pages.dev (the "Web Version"). In this policy, the "App" includes the Web Version unless we say otherwise. This policy explains what information the App collects, how we use it, who can see it, and the choices and rights you have. It applies to everyone who uses the App, including users in the United States, Canada, Australia, New Zealand and Singapore.

This is an English translation of our Japanese privacy policy (プライバシーポリシー). Both describe the same practices. If the two versions differ, the Japanese version prevails. This does not limit any right you have under the mandatory privacy or consumer protection laws of the place where you live.

The short version

1. Information we collect

We do not collect your contacts, precise location, health information, browsing history or payment information. The App has no in-app purchases.

Sources: we collect this information from you (what you enter), from your device (for example the notification token and App version), and through the service providers listed in section 4. Information related to advertising is collected directly by Google through the AdMob software in the App.

2. How we use information

We do not use the contents of your events, lists, notes, Board posts or photos for advertising, and we do not pass them to Google AdMob.

We do not send marketing emails or newsletters. News about the App is shown only in "News from FamShare" in the App. Apart from emails needed to sign in (such as an email to verify your address or reset your password), we email you only to reply to a message you sent us.

3. Who can see your information

4. Service providers

The App uses the following services. Each company handles information under its own policies.

Except where required by law, we do not provide or sell your personal information to any third party other than these companies.

5. Advertising and your choices

FamShare is free and shows small banner ads, plus an optional video ad you can choose to watch. The ads are provided by Google AdMob. Google may use the information described in section 1 to show ads, including ads based on your interests, to limit how often an ad is shown, to measure ads, and to prevent fraud. Learn more in How Google uses information from sites or apps that use its services.

6. How long we keep information, and deletion

7. Where your information is stored (international transfers)

YS Studio is based in Japan. Our service providers (Cloudflare, Google and Apple) are based in the United States and operate data centers in many countries, so your information may be stored and processed outside your country (and, for Canadian residents, outside your province), for example in the United States and Japan. Our main database and our photo and file storage (Cloudflare D1 and R2) are located in Cloudflare's Asia-Pacific (APAC) region. When information is sent to or from your device, it may also pass through, and be temporarily cached in, Cloudflare's data centers in other countries. Firebase Authentication (sign-in) runs only from data centers in the United States. Privacy laws in these countries may differ from those where you live. We use these providers only to run the App as described in this policy.

8. Children

You must be at least 13 years old to use the App yourself. The App is not directed to children under 13, and we do not intend to collect personal information from children under 13. Children under 13 should not create an account or use the App themselves; instead, a parent or guardian can represent them in the App with a label (for example, to show which events are a child's). Information that parents and guardians enter about their children (such as a name, a label or a birthday) to plan family life is handled as content they enter. In Quebec, users under 14 may use the App only with the consent of a parent or guardian. If you believe a child under 13 has given us personal information, a parent, guardian or the child can contact us at ys_studio_info@sketch-surgeon.com. After confirming the request, we will delete the account and the information that person entered, including shared events and board posts in their calendar and photos they sent to other people's calendars. We don't record who made each edit to another person's items, so we look for those edits from the details you give us and delete them after checking with the owner of that calendar.

Laws of certain US states: on iPhone and iPad, when your device's region is the United States and Apple treats you as covered by these laws, we receive your age category from the App Store. If you are under 18, or your category is unknown, the App does not show personalized ads or ask for permission to track. We use your age category only on your device, to comply with these laws and to apply this setting. We do not store it or send it to our servers or to third parties (ad requests only carry a setting that asks for non-personalized ads). On Android, when your device's region is the United States, we may receive your age category from Google Play. We use it only to comply with these laws, not for advertising, and we do not store it or send it to our servers or to third parties. If it shows that the Google Account on the device is under 13, the App stops new sign-ins and registration; if you are already signed in, it shows a notice and a way to delete the account, and does not delete or sign out automatically. When your device's region is the United States, the App shows only non-personalized ads to everyone on Android, whatever your age, because Google's rules do not allow age categories to be used for advertising.

If we learn a user is under 13 (iPhone and iPad): if the App Store's age category shows that the Apple Account on the device is under 13, the App does not load ads. It also stops new sign-ins and registrations, so the App can be used only without signing in, with data kept on the device. If an account is already signed in, the App does not delete it automatically, because a parent's account may be in use on a child's device; instead it shows a notice and a way to delete the account. The only thing kept on the device is a mark that the notice was closed, which does not include the age category. We rely only on the App Store's age category and do not check age in any other way.

9. Security

Communication is encrypted, and our server restricts access so that only you can access your personal data. However, no method of transmission or storage on the internet is completely secure, and we cannot guarantee absolute security. If a data breach occurs that is likely to cause serious harm, we will notify you and the relevant authorities as required by applicable law.

10. Your rights

You can ask us for access to, correction of, or deletion of your personal information. You can also edit and delete your information in the App, and delete all of it with "Delete Account". For other requests, please email us at the address below from the email address linked to your account (so that we can confirm the request comes from you). We will respond within the time required by applicable law. We will not treat you differently for exercising your rights.

You can also use the App without signing in, and you may use any display name you like (you do not have to use your real name).

11. Additional information for US residents

Some US states (such as California, Virginia, Colorado, Connecticut, Utah and Texas) give their residents specific privacy rights. Depending on where you live, you may have the right to know what personal information we collect and how we use and disclose it, to access it, to correct it, to delete it, to opt out of the "sale" or "sharing" of personal information or of targeted advertising, and to appeal our decision on your request.

12. Additional information for Australian residents

We handle personal information in line with the Australian Privacy Principles under the Privacy Act 1988 (Cth). You can use the App without signing in or under a pseudonym (any display name). Information may be disclosed to the overseas service providers described in sections 4 and 7, for example in the United States and Japan. If you have a complaint about how we handled your personal information, please contact us first; we aim to respond within 30 days. If you are not satisfied with our response, you can contact the Office of the Australian Information Commissioner (OAIC) at www.oaic.gov.au.

13. Additional information for New Zealand residents

We handle personal information in line with the Information Privacy Principles under the Privacy Act 2020. You have the right to ask for access to, and correction of, your personal information, and we will respond within 20 working days. Information may be disclosed to the overseas service providers described in sections 4 and 7. If you have a complaint, please contact us first. If you are not satisfied with our response, you can complain to the Office of the Privacy Commissioner at www.privacy.org.nz.

14. Additional information for Canadian residents

We handle personal information in line with the Personal Information Protection and Electronic Documents Act (PIPEDA) and, for residents of Quebec, the Act respecting the protection of personal information in the private sector (as amended by Law 25).

15. Additional information for Singapore residents

We handle personal data in line with the Personal Data Protection Act 2012 (PDPA).

16. Additional information for Hong Kong residents

We handle personal data in line with the Personal Data (Privacy) Ordinance (Cap. 486).

17. Additional information for Malaysia residents

We are based in Japan and have no office or equipment in Malaysia. Even so, we follow the main principles of the Personal Data Protection Act 2010 (PDPA) for people in Malaysia.

Ringkasan dalam Bahasa Melayu: YS Studio (Jepun) mengumpul dan menggunakan data peribadi anda hanya untuk menyediakan FamShare seperti yang diterangkan dalam dasar ini. Data anda mungkin disimpan dan diproses di luar Malaysia, contohnya di Amerika Syarikat dan Jepun. Iklan dalam aplikasi mungkin diperibadikan melainkan anda menghadkannya dalam tetapan peranti. Anda boleh meminta akses atau pembetulan data anda, menarik balik persetujuan dengan memadam akaun anda, atau menghubungi kami di ys_studio_info@sketch-surgeon.com.

18. Changes to this policy

When we change this policy, we will post it on this page, and we will let you know about important changes in the App.
