Privacy Notice for Dharahara Stack

Dharahara Stack (“the app”) is developed and published by AlphergMirai, a software studio operating from Japan. This notice sits alongside our studio privacy policy; where the two differ, this notice governs the app. It applies to version 1.1 and later.

1. The short version

2. Information kept on your device

To run the game, the app saves the following only in its own storage on your device. It is never sent to us.

• Free Mode scores and best score, floors and combos;
• Build Journey progress, medals, best times, alignment and perfect-drop records;
• Today’s Nine results for up to the last 60 recorded days;
• tutorial progress, and your sound, haptic, reminder and phone-time lighting preferences;
• whether you chose to share scores with Game Center;
• your Mudra balance, power-ups and tower styles, and the Apple transaction IDs of Mudra purchases (so a purchase is never credited twice);
• pictures and details of towers you choose to keep in the in-game album (up to 24).

Today’s Nine uses the date in UTC to choose a repeatable wind pattern. Optional day and night lighting uses your device’s clock. Neither feature uses your location or an internet service.

3. Optional reward videos (Google AdMob)

In Free Mode, when your tower falls you may choose to watch a short video to continue the same run once. Videos are shown only after you tap “Watch a video to continue”. There are no banner ads and no forced full-screen ads, and Build Journey and Today’s Nine contain no ads.

The videos are provided by Google AdMob (Google LLC / Google Ireland Limited). To request, show and measure an ad, and to prevent fraud, Google’s software in the app may process information such as:

• device information (model, operating system, language) and an app-scoped device identifier;
• IP address and the approximate location derived from it;
• ad interactions (whether an ad loaded, was shown, completed or tapped), and diagnostic data such as ad load times and errors.

The app does not ask for App Tracking Transparency permission, so Google cannot access your device’s advertising identifier (IDFA) through the app. Google processes this information under its own policies: see How Google uses information from sites or apps that use its services and the Google Privacy Policy. We only receive aggregated, non-identifying reports (for example, how many videos were shown).

Consent in the EEA, UK and Switzerland. If you are in these regions, the app shows Google’s consent message before any ad is requested, where you can accept or decline personalised advertising. If you do not watch videos, no ad is requested at all apart from Google preparing one in the background so it is ready if you choose to watch.

4. Optional Game Center leaderboards and achievements (Apple)

If you tap “Connect to Game Center” on the Records screen, your best Free Mode score, your fastest Today’s Nine time and the Build Journey heights you have completed are sent to Apple Game Center, so they appear on worldwide leaderboards and as achievements under your Game Center nickname. Apple processes this under the Apple Privacy Policy. We can see leaderboard entries in the same way as other players, but we do not receive your Apple Account details. You can stop sharing future scores in the app at any time, and manage Game Center in iOS Settings.

5. In-app purchases (Mudra)

Mudra is the game’s coin. You earn it by playing (one Mudra for each perfect drop) and can optionally buy Mudra packs (“Mudra”, “Silver Thaili”, “Gold Thaili”). Mudra is spent inside the game on power-ups (Freeze, Slow-mo, Revive) and tower styles. Mudra has no cash value and cannot be exchanged or transferred.

Purchases are made through Apple’s App Store and are governed by Apple’s terms. Apple handles the payment; we never see or store your name, card or payment details. Apple tells the app only that a purchase was completed, with a transaction ID, so the Mudra can be added. Your Mudra balance and items are stored only on your device; there is no account, so they are not restored if you delete the app or move to a new device. Refunds are handled by Apple at reportaproblem.apple.com. You can turn off in-app purchases in iOS Settings → Screen Time → Content & Privacy Restrictions.

6. Reminders

If you allow notifications, the app schedules up to three gentle reminders on your device (about one, three and seven days after you last played), plus at most one greeting on the first evening of Dashain and of Tihar. They are created entirely on your iPhone; no server and no data are involved. You can turn them off in the game’s settings or in iOS Settings → Notifications.

7. What the app does not do

• It does not ask for your name, email address or any other contact details, and has no account.
• It does not request access to your location, contacts, camera, microphone or photo library. Saving a picture happens only through the iOS share sheet, when you choose to.
• It contains no third-party analytics SDK.
• It does not track you across other companies’ apps or websites, and we do not sell or share your personal information.

8. Sharing pictures

Sharing is optional. When you tap “Save or share picture”, the app creates a temporary picture of your tower and opens the iOS share sheet, where you choose the destination. The app or service you pick then handles that picture under its own privacy policy. The game never publishes pictures by itself, and the temporary file is removed when sharing ends.

9. Apple services

Apple may process App Store, download, device-backup and diagnostic information under Apple’s own privacy policy and your device settings. If you have chosen in iOS Settings to share analytics with app developers, Apple may provide us with anonymous crash reports, which we use only to fix problems.

10. Children

Dharahara Stack is a general-audience game. It is not directed specifically at children, and we do not knowingly collect personal information from anyone, including children. Reward videos only appear when a player chooses to watch one. If you are a parent and have a concern, please contact us.

11. Deleting your data

You can delete individual keepsakes from the in-game album. Deleting the app removes all of its data from your device, including any Mudra and items; offloading the app may keep it. Apple device backups may retain or restore app data according to your iCloud or computer backup settings. Game Center scores are managed by Apple in your Game Center settings. Pictures you already saved or shared elsewhere must be removed from those places separately. To control information processed by Google, see My Ad Center.

12. Your rights

Because we hold no personal information from the app, there is normally nothing for us to access, correct or delete. Depending on where you live (for example under the GDPR or Japan’s APPI) you have rights over your information; for data processed by Google or Apple, please use their tools and contacts linked above. If you contact our support, we use what you send only to answer you, as described in our studio privacy policy, and you can ask us to delete it at any time by writing to privacy@alphergmirai.com. We respond within 30 days.

13. Changes to this notice

If a future version changes what the app does with information, we will update this notice and its effective date before that version is released, and describe the change in the release notes.
