Spin Lab Privacy Policy

Effective date: 2026-11-12

Spin Lab (package com.numford.spinlab) is an Android game developed by Numford ("we", "us"). It is a top-down arena battle for spinning tops. This policy explains what Spin Lab does and does not do with information.

Summary

  • Spin Lab itself does not collect personal data and has no server.
  • There is no Spin Lab account, no ads, no analytics and no crash reporting.
  • If you have a Play Games profile on this phone, Play Games may sign you in automatically when the game starts. Your progress, scores and achievements are then synced through Google Play Games (see "Google Play Games" below). To opt out, change the Play Games app settings on your phone, or remove Spin Lab from your Play Games profile. The game is fully playable without Play Games.
  • An optional one-time purchase, the Supporter Pack, is handled by Google Play. We never see your payment details (see "Purchases" below).
  • Your progress, stars, unlocked tops and settings are stored on your phone.
  • Motion sensor readings are used on your phone only, while you play, and are never stored.

Information we collect

We do not collect, store or share personal data ourselves. Spin Lab does not ask for your name, email address, phone number, contacts, location, photos or messages, and it does not track you across apps or websites.

Google Play Games (optional)

Spin Lab can use Google Play Games Services for leaderboards, achievements and a cloud save. If you have a Play Games profile on this phone, Play Games may sign you in automatically when the game starts. Your progress, scores and achievements are then synced through Google Play Games. If you are not signed in, the game shows a "Sign in to Play Games" button. To opt out, change the Play Games app settings on your phone, or remove Spin Lab from your Play Games profile. The game is fully playable without Play Games.

When Play Games is signed in:

  • Google identifies you by your Play Games profile (gamertag, avatar and player ID). Spin Lab does not receive your email address and does not copy your Play Games name or avatar anywhere else.
  • Spin Lab asks Google to store your leaderboard scores (total stars, best Survival run, fastest win against the boss and Daily challenge score), your achievement unlocks, and one cloud save named "arena". The cloud save holds the same progress data described below (stars, unlocked tops and finishes, bests, daily results and streak, settings) plus the sync markers (which scores and achievements were already sent, and the Play Games player ID they belong to). It does not hold purchase tokens, the Supporter Pack flag or payment details. Leaderboard scores can be seen by other players according to your Play Games profile visibility settings.
  • Once Play Games has started, its SDK may also collect analytics and diagnostics data to keep the service stable. Google handles all of this under the Google Privacy Policy: https://policies.google.com/privacy. Google describes this data on https://developer.android.com/games/pgs/data-collection.
  • Data is sent to Google over an encrypted connection. We do not run a server and cannot read your data apart from what Google makes available to the game for your account.

How to stop and delete:

  • Remove Spin Lab from your Play Games profile (in the Google Play Games app, open your profile and delete the data for this game) to delete the scores, achievements and cloud save Google holds for it.
  • You can delete the whole Play Games account from your Google Account at https://myaccount.google.com/.
  • Then uninstall Spin Lab to remove the data on your phone. Email support@numford.com if you want help with a deletion request.

Purchases

Spin Lab has one optional in-app purchase, the Supporter Pack. It is a one-time, cosmetic-only purchase (extra top and bowl finishes and a supporter badge). The purchase is made and paid for through Google Play Billing. Google, not us, collects and processes your payment details and handles refunds under Google Play's terms. We never receive your card or other payment details, and we do not run a server that sees your purchases.

On your phone, Spin Lab asks Google Play which items you own, so it can unlock what you bought, restore it after a reinstall or on a new phone, and confirm it again each time the game starts. It keeps a cached "owned" flag in its private storage so your finishes still work offline. We do not send purchase information to anyone, and it is not part of the Play Games cloud save.

Data stored on your device

Spin Lab saves your progress on your phone: your stars for each rival, which rivals, bowls, tops and finishes you have unlocked, the top and finishes you picked, your daily challenge results and streak, your best scores and times, your settings (such as steering mode and reduced graphics), a cached flag for the Supporter Pack, and sync markers (which scores and achievements were already sent to Play Games, and the Play Games player ID they belong to). This is kept in the app's private storage on your phone. It is excluded from Android cloud backup and device-to-device transfer. Uninstalling the app or clearing its storage deletes it from your phone (a Play Games cloud copy, if you signed in, is deleted as described above).

Motion sensors

Spin Lab uses the accelerometer to measure how you tilt the phone, so you can steer your top. Sensors are read only while a match is on screen, and they stop when you leave the screen or the app goes to the background. The readings are used right away to drive the game. They are held in memory only, are never written to storage, never logged and never sent anywhere. If your phone has no such sensor, you can steer by dragging instead and the rest of the app works.

Vibration

Spin Lab uses the vibration motor for haptic feedback on impacts and dashes. No information is collected from it.

Third parties

Spin Lab contains no third-party advertising, analytics, crash reporting or tracking code. The third-party components that talk to Google services are Google Play Games Services and Google Play Billing, described above; Play Games is used when it is available on your phone and you have not opted out, and Play Billing is checked on your phone each time the game starts, to confirm whether you own the Supporter Pack; a purchase happens only if you choose to buy. We do not share information with anyone else.

Children

Spin Lab is intended for people aged 13 and over and is not directed at children under 13.

Changes

If this policy changes, the updated version will be published at the same place with a new effective date.
