One Bad Bulb — Privacy Policy
Effective date: November 4, 2026
The One Bad Bulb Android app is built by MindGap Technologies LLC, a small studio in San Antonio, Texas. The app shows a dark string of holiday lights and lets you tap bulbs to swap them until you find the one bad bulb that makes the whole string light up. This policy explains what the app does and does not do with your data. It covers the One Bad Bulb app only; for the mindgap.tech website, see our general privacy policy.
Data collection and sharing
We do not collect, transmit, store, or sell any personal data. The app has no accounts, no sign-in, and no analytics, and we receive nothing about you.
The only things the app keeps on your device are game state (whether your string is currently lit, the date it was fixed, and your tap counts for the stats line) and a flag noting that you have seen the first-run hint. None of it is information about you. We never receive any of it, and the app itself sends it nowhere. If Android's own backup is turned on for your phone, the system may include it in your device backup or carry it to a new phone, under your Google account settings; we have no access to that backup.
How your data is processed
Everything happens on your device. The app reacts only to your taps; it does not use the camera, microphone, location, or motion sensors.
The app vibrates when you swap a bulb, which is why it requests the vibration permission. Once you have fixed the string, the app can schedule a single local reminder notification for December 1 ("your lights broke again"). On newer Android versions this needs the notification permission, which you can decline; the reminder is created and shown entirely on your device, with no push service and no server involved. It also asks to be woken when the phone starts, only so that reminder survives a restart. It requests nothing else.
Network activity
The app performs no network activity and does not request internet access at all; it works entirely offline.
If you choose to share your "fixed" card, the app hands the image to the Android share sheet, and the app you pick there delivers it. We never see the card, and nothing is sent anywhere unless you decide to share it.
Advertising and analytics
The app shows no advertising and contains no third-party analytics, tracking, or advertising SDKs. It does not build a profile of you and does not track you across apps or sites.
Accounts
There is no account and no sign-in. Every feature works without providing any personal information.
Children's privacy
This is a general-audience utility. It is not directed at children, does not knowingly collect any information from children, and — because it collects no personal data — has nothing to collect from users of any age.
Changes
If the app's data practices ever change, this policy will be updated first, with a new effective date. Material changes will be reflected here before they take effect.
