Privacy Policy

App: Pochitto Pocket (formerly Osoroi Sagashi) ("the App")

Provider: Tyzo Inc. (Representative: Taisuke Akita)

Last updated: October 6, 2026

Thank you for using the App. The App is designed with privacy first, so that children and parents can use it with peace of mind.

1. Information We Collect

The App does not collect any personal information or usage data.

- We do not collect personal information such as names, email addresses, location, photos, audio or advertising identifiers

- The App does not use the microphone or camera

- No sign-up or account is required

- The App contains no advertising, analytics or tracking

- The App works fully offline and never connects to the internet

2. Information Stored on Your Device

To let your child keep playing, the App stores the following information on your device only. We never receive it, and the App never sends it off the device.

- Children added to the App (up to 4): a nickname entered by a parent (up to 8 characters, optional), the animal icon chosen, and the last age group selected

- Play records (when, which game, whether the answer was correct, and which choice was picked when it was wrong)

- Reward stars and stickers, the positions of stickers placed in the sticker book, and the kinds of stickers collected

- The difficulty level for each game

- Play time (time played per day, kept for the most recent 14 days only; older days are deleted automatically) and the daily limit set by a parent

- Settings such as music and sound-effect volume, read-aloud on/off, fixed difficulty and display language (English/Japanese)

- Whether the update notice and the App Store rating request have been shown

When more than one child is added, records, stars, stickers, levels and play time are kept separately for each child. Nicknames are only shown on screen and are never sent off the device.

Deleting data

- Parents can delete data at any time in Parent Mode:

  "Edit child": deletes that child and their records

  "Delete play records": deletes play records only (stars and stickers are kept)

  "Erase all data": deletes all of the information above and returns the App to its first-launch state

- Deleting the App from the device also deletes all of the information above

Device backups

If you use iCloud Backup or another whole-device backup, iOS may include the information above in your backup. Backups are managed in your own account, and we cannot access their contents.

3. Read-Aloud

Questions are read aloud using the speech synthesis built into iPhone and iPad. Speech is generated on the device, and no audio or text is sent anywhere. The App never records your child's voice.

4. Children's Privacy

The App is designed for young children. In line with the principles of the U.S. Children's Online Privacy Protection Act (COPPA), Japan's Act on the Protection of Personal Information and the EU GDPR (protection of children's data), we do not collect personal information from any user, including children.

Features for parents (play records, settings, adding children, deleting data, rating the App and the feedback form) are behind a simple check that only parents can pass (a two-digit addition), so children cannot open them by accident.

5. Sharing with Third Parties

Because the App collects no information, nothing is shared with third parties.

6. Features Provided by Apple

- "Support the app" in Parent Mode opens the App Store review page (provided by Apple). Apple's rating prompt may also appear when Parent Mode is opened (at most once per version). Ratings and reviews are sent through Apple's systems, and we receive no information that identifies you

- If "Share with App Developers" is turned on in your device settings, Apple may provide us with crash reports and usage statistics that do not identify individuals. We use these only to improve the quality of the App

7. Advertising and In-App Purchases

- The App does not show advertising

- The App has no in-app purchases

8. External Links and Feedback Form

The App contains the following external links, and only behind the parent check (addition). There are no external links on the screens children use.

- The App Store review page (see section 6)

- The ideas and feedback form: "Send an idea" in Parent Mode opens a Google Form in your browser

The feedback form is filled in and submitted by parents at their own choice. The App itself sends nothing. What you enter in the form (your feedback, your child's approximate age, the language you use, and your email address if you would like a reply) is used only to improve the App and to reply to you if requested, and is never shared with third parties. Form submissions are processed by Google LLC, and Google's privacy policy applies.

9. Changes to This Policy

We may update this policy when the App changes. Any important changes will be announced on this page. The App will continue to be designed not to collect information.
