What stays on your device
Your progress (filled contracts, stars, the factories you built, your daily contract results, the free-mode floor), your settings and the time of the last ad are stored on the device only. There are no accounts, and no servers of ours receive gameplay data apart from the optional world ranking described below. Uninstalling the app, or "Delete my data" in Settings, deletes them.
What leaves your device
- Once a day the app downloads the public list of other Kodalab apps (kodalab.pt). The request carries no identifier.
- Share codes are only sent where you choose to share them, through Android's share sheet. A code contains the contract (or the date of the daily contract) and the layout of your factory, nothing else. The text that goes with it, shown to you before sending, adds how much you delivered and the cost.
- Only if you ask for it: after you pass the daily contract, the app offers the world ranking. If you choose a name (up to 16 characters) instead of "Not now", it sends that name, the score, the date, a timestamp and a random identifier created on your device to kodalab.pt. Viewing the ranking sends only that random identifier and the date. Our server keeps IP addresses only as a salted, truncated hash, to limit abuse. No account, no e-mail, no contacts, no location.
- Ads and the consent form are loaded from Google (see below).
Advertising
The app is free and shows ads through Google AdMob: a banner that never covers the controls, a full-screen ad at most after a completed contract (never in your first session, and spaced out), and rewarded ads only in free mode when you tap a button for an optional extra (a load map or more machine slots) — never automatically, never needed to fill a contract. In the EEA and UK you are asked for consent through Google's form first, and you can change it in Settings ("Ad privacy options"). AdMob may use the Android advertising id to serve and measure ads; you can reset or delete it in Android settings. See how Google uses data in ads.
Notifications
A daily reminder is only scheduled if you say yes (offered after the first completed contract, never at first launch). It is a local notification created on the device; you can turn it off in Settings.
Reviews
After a very good result the app may ask Google Play to show its rating dialog. Google Play decides whether it appears; the app never sees your rating.
Purchases
There are no purchases in this app.
Children
The app is not directed at children under 13 and does not knowingly collect personal data from them.
Your rights
Everything the app stores is on your device: "Delete my data" in Settings or uninstalling removes it. The only data about you on our server is your ranking entry, if you joined the world ranking; to delete it, e-mail joel.gomes@kodalab.pt with the name shown on the ranking. For data processed by Google for ads, use "Ad privacy options" in Settings, your Android ad settings, or Google's tools linked above.
