Last Step · Ninth Bit Studio

Privacy Policy

Effective September 27, 2026 · Applies to the Last Step Android app (package com.ninthbit.voidstep)

At a glance

: We collect: nothing ourselves. Your puzzles, stars, streak and settings live on your own device and never leave it.
: We don't collect: your name, email address, phone number, precise location, photos, contacts, or any payment information. Last Step has no accounts, no sign-in and no servers of its own.
: Google receives: your device's advertising ID when an ad is shown, and your purchase when you buy something — through the AdMob and Google Play Billing SDKs the app runs on. Buy the ad-free upgrade and the ad part stops entirely.

01Who we are

Last Step is developed by Ninth Bit Studio. This policy explains what information the app handles, why, and how you can control it. If anything here is unclear, write to us at ninthbitstudio@gmail.com.

02What stays on your device

Last Step is a single-player puzzle game with no accounts and no servers of our own. The following is stored only in the app's private storage on your phone, is never transmitted, and is not visible to us:

Which levels you've solved and how many stars each one earned.
Your daily puzzle history and current streak.
Duel results. Duels are played entirely on your device against the app itself — there is no matchmaking, no opponent server and no score submission.
Your settings: language, board and stone colours, sound and vibration, and which in-app items you own.

All of it is deleted the moment you uninstall the app.

03Advertising

Last Step shows ads — a banner below the board, a full-screen ad between regions, and short videos you can choose to watch for a hint or an extra attempt. These are served by Google AdMob, which collects your device's advertising ID and related technical data (device model, coarse region, app version) to select and measure the ad. We never see that data ourselves and we don't build advertising profiles.

If you're in the EEA, the UK or Switzerland, the app asks for your consent through Google's certified consent form before any personalised ad is requested. You can review or change that choice at any time with Settings → Ad privacy.

Buying Remove ads or the Everything pack switches ads off completely. After that the app requests no ads and no advertising ID is collected.

04Purchases

In-app purchases are handled entirely by Google Play Billing. Your payment details go to Google and never pass through the app — all Last Step receives back is whether a given item is owned. We don't store a purchase history, an order number or anything that identifies you as a buyer.

05Notifications

If you allow notifications, the app can remind you that a new daily puzzle is ready. The reminder is scheduled and fired locally by your own device; nothing is sent to us or to anyone else, and there are no push servers involved. You can turn it off in Android's app notification settings at any time.

06Third-party services

Last Step is built on two Google SDKs, each governed by Google's own privacy terms:

Google AdMob — serves and measures the banner, full-screen and rewarded ads.
Google Play Billing — processes in-app purchases.

There is no analytics SDK, no crash reporter and no social or advertising network beyond AdMob.

07Data retention & deletion

Because we hold nothing, there is nothing for us to delete. Still:

Game data (progress, stars, streak, settings) is wiped automatically when you uninstall Last Step.
Your advertising ID can be reset or deleted at any time from Android's Settings → Privacy → Ads, which also lets you opt out of ad personalisation device-wide.
Purchases are held in your Google account, under Google's own terms, and can be reviewed on Google Play's order history.
Anything else — write to ninthbitstudio@gmail.com and we'll help you sort it out or pass the request on to Google where it applies.

08Children's privacy

Last Step is not directed at children under 13 and we don't knowingly collect information from them. The game contains no real-money gambling, no chat and no user-generated content. It does contain ads, and purchases can be made with real money, so parents should be aware of both.

09Changes to this policy

If this policy changes, we'll update the effective date above. Continuing to use Last Step after a change means you accept the update.
