Privacy Policy

App: Ninefold Developer: Vytautas Zabielskas Contact: baltibytes@gmail.com Last updated: 2026-10-05

This policy explains what happens to your information when you use the app. The short version: the app has no account, collects nothing about you, and everything you play stays on your device.

What the app stores, and where

The app keeps the following only on your device:

• Your game results: for each game you finish, its score, the levels you reached, how many answers were right, typical response times, and when you played. The app uses these to set the difficulty, pick your daily workout, and show your progress.
• Your achievements: which ones you have earned and when, worked out on your device from your game results.
• Your versus matches: for each pass-and-play match you finish, your own score and place, and the game. The other players’ names and scores are only shown during the match and are never stored.
• Challenges you have played: which shared puzzles you have started, and your first score on each, so a replay doesn’t replace it. A challenge code holds a game, its puzzles and a score, and nothing about you; the app never sends one: you share it yourself, with the app you choose.
• Your settings: sound and its volume, vibration, the daily reminder and its time, and whether you have seen the welcome screen.
• Whether you have bought Unlimited, so the app works offline.
• How many free plays you have used today, for the free version’s daily limit.

None of this is sent to us or to anyone else. We have no server and no way to see it.

What the app does not do

• No account and no sign-in.
• No analytics, tracking or advertising, and no third-party advertising or analytics code.
• No location, contacts, photos, microphone or camera.
• No sharing or selling of data. There is nothing for us to share or sell.

Purchases

The one-time Unlimited purchase is handled by Google Play. The app asks Google Play whether you own Unlimited and what it costs in your country. Your payment details and purchase record are handled by Google under the Google Privacy Policy. The Google Play Billing library built into the app may also send Google technical information about purchase attempts, such as errors, under the same policy. We never see your payment details.

Backup to your Google account

If you have Android backup turned on, Android may include your game results, achievements and versus results in the backup it keeps in your Google account. That way your history can come back on a new phone. This is Android’s own backup, stored by Google, and we cannot access it. You can turn backup off, or delete backups, in your phone’s settings and your Google account.

Daily reminder

If you turn on the daily reminder, the app shows a notification on your phone at the time you choose. The reminder is created and shown on the device, with no server involved. You can turn it off in the app’s settings or in Android’s notification settings.

Sound and vibration

Sounds play only on your phone, at its media volume, and can be turned off or quietened in the app’s settings. The app can vibrate your phone briefly for right and wrong answers and level ups. Android grants this vibration permission when the app is installed; it gives no access to any of your data. You can turn vibration off in the app’s settings, and the app also follows your phone’s own touch-vibration setting.

Information Google Play may collect

Google Play may collect information about how the app runs, for example crash reports and performance data, and share it with us in summary form through the Google Play Console. This depends on your device settings and is covered by the Google Privacy Policy.

If you send feedback

More → Send feedback opens your own email app with a message to us. It is pre-filled with the app’s version, your Android version and your phone model, which help with bug reports, and you can edit or delete any of it before sending. We receive only what you choose to send, and use it only to answer you and improve the app. Nothing is sent unless you send it.

Deleting your data

Because your data is only on your device, you control it:

• In the app: More → Settings → Reset all progress deletes every result. Each game’s progress screen can also delete that game’s results. Achievements you have earned are kept after a reset; clearing the app’s storage or uninstalling deletes them too.
• Uninstalling the app, or clearing its storage in Android’s settings, deletes everything the app stored.
• To delete a backup, use your phone’s backup settings or your Google account.

Children

The app is meant for teenagers and adults and is not directed at children under 13. It collects no personal information from anyone, children included.

Changes to this policy

If the app ever starts handling data differently, for example by adding optional online features, we will update this policy before that change reaches you. We will also change the date above. Any online features would be optional, and the app would ask before anything leaves your device.
