Notification Vault Privacy Policy

Effective date: October 23, 2026

This Privacy Policy explains how Notification Vault, provided through the Kartily platform, handles information when you use the Notification Vault mobile application.

In short: your notifications are stored only on your device and are never uploaded. The app connects to our server only to check for updates and, if you choose, to send anonymous feedback. It requires no account and does not sell any information.

1. What the app does

Notification Vault keeps a copy of the notifications shown on your Android device so you can read, search, and manage them later, even after they have been dismissed or removed by the app that sent them.

2. Notification access

To provide this feature, Notification Vault uses Android's notification access permission, which you grant in your device settings. With this permission the app reads the notifications displayed on your device, such as the sending app's name, the notification title and text, and the time it was received. This access is used only to store notifications in the vault on your device. You can turn notification access off at any time in your device settings.

3. Information stored on your device

• Notifications captured while notification access is enabled, including app name, title, text, and time received.
• Your settings, such as theme, retention limits, duplicate filtering, and biometric lock preference.
• Favorites and ignore rules you create.

This information is stored only in the app's private storage on your device. Notifications may contain personal information, including information about other people who message you. Notification content is never sent to our server or to anyone else, unless you choose to share it as described in section 5.

4. Information sent to our server

Notification Vault connects to the Kartily server (the Skyscraper API) only for these two features. Everything else works offline, and the app keeps working if the server cannot be reached.

• Update check: when the app starts, it asks which version is current and whether a service message is active. The request contains only the app's identifier, the platform (Android), and the installed version number. It contains no account, device identifier, advertising ID, or app content.
• Feedback: when you choose to send feedback from the app, we receive the category, title, and message you write, and the app version and platform. If you choose to include device details, we also receive the Android version and phone model. Feedback is anonymous: it is not linked to an account, and we do not ask for or accept your name or email address. Please do not include personal information in your message.

Like any website, our server receives your device's IP address when the app connects. It is used to deliver the response, to protect the service from abuse, and in short-lived server logs for security and troubleshooting. To limit how often feedback can be sent from one device, we store a one-way keyed code derived from the IP address, never the address itself. We do not use this information to identify you, build a profile, or track you across apps, and we do not sell it.

5. Information you choose to share

Your stored notifications leave your device only when you take one of these actions:

• Copy or share: when you copy a notification or code, or share a notification with another app you select.
• Export: when you export notifications to a TXT, CSV, or JSON file and send or save it somewhere you choose.

Once shared, information is handled by the app, service, or recipient you choose, under their own privacy terms. Feedback never includes stored notifications.

6. Biometric lock

The optional biometric lock uses your device's fingerprint or face recognition through Android. Biometric data is handled entirely by Android and is never accessible to, or stored by, Notification Vault.

7. Third-party services

Notification Vault does not include third-party analytics, advertising, or tracking. Google Play processes store, installation, and any purchase information under Google's own terms. The "More Apps" option opens the Google Play Store, which is operated by Google.

8. Retention and deletion

Stored notifications remain on your device until you delete them or they are removed by the retention and purge settings you choose. Uninstalling Notification Vault, or clearing its storage in Android settings, permanently deletes all stored notifications and settings.

Feedback you send is kept on our server for as long as needed to review and act on it, and is then deleted. Server logs are kept for a short period. Because feedback is anonymous, we cannot find it by your name; to ask us to delete feedback, contact us with the date you sent it and its title.

9. Security

Your data is kept in the app's private storage, which other apps cannot access under Android's security model. Connections to our server use HTTPS. You can add an extra layer of protection by enabling the biometric lock. No system can guarantee absolute security.

10. Children's privacy

Notification Vault is not directed to children under 13 and does not knowingly collect personal information from children under 13.

11. Your choices

You can grant or revoke notification access, ignore notifications from specific apps or with specific content, set retention limits, delete stored notifications, enable or disable the biometric lock, choose whether to send feedback and whether to include device details, and uninstall the app at any time.

12. Changes to this policy

We may update this policy when features or requirements change. The effective date will be updated when a revision is published.
