Privacy & Terms
Effective date: October 28, 2026
This Privacy Policy explains how Vaulabs.ai ("we", "us") handles information in connection with our Android applications, including Battery Limit Notifier, Fortune Machine, and future Vaulabs.ai apps (together, the "Apps"). By installing or using an App, you agree to the practices described here.
Information We Collect
We do not require you to create an account or provide personal details such as your name or email address to use our Apps. Every App collects basic device information (device model, OS version, language, and screen size) to keep it working correctly across devices. Beyond that, what's collected varies by App, since different Apps use different SDKs:
| App | Analytics / crash reports | Advertising (AdMob) | In-app purchases |
|---|---|---|---|
| Battery Limit Notifier | Firebase Analytics & Crashlytics | Banner ads | Yes — Pro unlock (Google Play Billing) |
| Fortune Machine | None | Banner & interstitial ads | None |
This table is updated whenever a new Vaulabs.ai app launches or an existing app's data practices change.
Advertising identifiers (your device's Advertising ID or equivalent) are collected by Google AdMob for any App showing ads, in whatever ad format that App uses. We never collect precise location, contacts, photos, or any data unrelated to an App's core function, in any App.
Analytics — Firebase
For Apps that use it (see table above), we use Firebase Analytics (a Google service) to understand how the App is used in aggregate — for example, which features are opened most often — so we can prioritize fixes and improvements. Firebase Analytics data is processed under Google's own privacy terms.
Monetization — AdMob & In-App Purchases
Our free Apps are supported by Google AdMob ads, in the banner and/or interstitial formats listed in the table above for each App. AdMob may use your advertising identifier to show ads that are relevant to you and to measure ad performance; you can reset or limit ad personalization from your device's Google Settings at any time. Apps that offer a Pro/paid unlock (for example, to remove ads) process that purchase through Google Play Billing — we never see or store your payment card details, which are handled entirely by Google Play.
Data Retention
For Apps that use Firebase (see table above), analytics and diagnostic data is retained by Firebase for up to 14 months from collection, after which it is automatically deleted or anonymized, in line with Firebase's default retention settings. Advertising identifiers are retained by AdMob according to Google's own advertising data policies, not by us directly — we do not maintain a separate database of user data.
Children's Privacy
Our Apps are not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with information, contact us at the address below and we will remove it.
Your Rights
You can opt out of personalized ads from your device settings, and uninstalling an App stops all further data collection from that device. To request details about data associated with your device, or to ask a question about this policy, email us — see Contact below.
Changes to This Policy
We may update this policy as our Apps evolve. Material changes will update the "Effective date" above; continued use of an App after a change means you accept the revised policy.
