How ButterPass handles data
TL;DR: ButterPass stores your card data on your device only. There are no accounts and no cloud storage. Ads show unless you buy Premium; Google uses the Advertising ID for ads, and we do not store or link it to your cards.
ButterPass ("App," "we," "us," or "our") is developed and operated by William Termini (ABN 47 283 458 067). This Privacy Policy explains what data we collect, how we use it, and your choices regarding your information. This policy applies to all users of ButterPass on Android.
Any card information you enter, scan, or import (names, barcodes, QR codes, images) is stored exclusively on your device. This data is never sent to our servers or any third party.
While we do not host a server to collect your data, the following services process technical identifiers:
We process data locally to provide:
ButterPass uses Android's Scoped Storage model. We can only access files you explicitly grant permission to, and our app data is sandboxed from other apps.
Ads & Premium: We show banner ads powered by Google Mobile Ads unless you purchase Premium.
Consent (GDPR/CCPA): In regulated regions, we use a required consent flow. If you refuse consent, ads will be non-personalized.
Opt-Out Rights: Your right to opt out of personalized tracking applies in jurisdictions like the EU (GDPR) and California (CCPA/CPRA). In other regions, ads may be displayed based on Google's default settings. You can adjust ad personalization in Android system settings.
Your Control: You can delete individual cards or the entire database within the app at any time.
Uninstalling: Uninstalling ButterPass deletes all card data from your device storage. If you manually exported a backup file, that file remains under your control and must be deleted manually.
Data Controller Status: Under privacy laws like the GDPR, William Termini is the Data Controller for the App. Because your card data is stored exclusively on your device, we have no technical access to it.
Right to Access/Delete: You exercise these rights yourself by viewing or deleting cards within the app.
ButterPass is not intended for children under 13. We do not knowingly collect any information from children.
