Privacy Policy

Apps: "PonNikki" (one-time purchase version) / "PonNikki with Ads" (version with ads) (Android and iOS)
Effective date: August 10, 2026 / Last updated: October 18, 2026 (added a section for users in the United Kingdom). If the English and Japanese versions differ, the Japanese version prevails.

1. Basic policy

The app processes and stores everything on your device: your diary entries (tags, notes, and photos), plans, habit checks, characters, and settings. Your diary is never sent to an outside server. There is no cloud sync.

2. Accounts

You don't need an account to use the app. We never ask for personal information such as your name or email address.

3. Information stored on your device

The following information is stored only in your device's storage. It is never sent outside, and you can delete it at any time with the app's delete features or by uninstalling the app.

Photos are resized on your device when saved and kept in the app's own storage area. The Look Back lock is a feature to prevent viewing; it does not encrypt the saved data.

4. Information sent outside the app

4.1 Showing ads (version with ads only)

"PonNikki with Ads" uses Google AdMob (provided by Google LLC) to show ads. When ads are shown, the following information is sent to Google LLC.

For details, see Google's privacy policy (https://policies.google.com/privacy).

The one-time purchase version "PonNikki" does not include the ad SDK at all, so none of this information is sent.

Your diary (tags, notes, and photos) is never sent for advertising (in both versions).

4.2 Users in the United Kingdom (version with ads only)

If you use "PonNikki with Ads" in the United Kingdom (or in the EEA or Switzerland), the app shows Google's consent form (Google's User Messaging Platform) before it loads ads, and asks for your consent to the uses described in 4.1.

5. Reminder notifications

Reminder notifications are local notifications handled entirely on your device. The app does not connect to an outside server to send them.

6. Exporting backups

The backup feature creates a backup file on your device when you ask it to, and you choose where to save it with your device's share feature. The app never sends it anywhere automatically. You are responsible for keeping the exported file safe.

7. Sharing with third parties

Except as described above, we do not share your information with third parties.

8. Children's privacy

The app is not directed at children under 13, and we do not knowingly collect personal information from children.

9. Changes to this policy

If we change this policy, we will announce it on this page.
