Your privacy is our highest priority. This Privacy Policy explains how Backdrop ("we," "our," or "the App") handles your information. Our core philosophy is minimalism, which extends to how we treat your data: we only collect what is absolutely necessary for the App to function.
Backdrop is designed to operate locally on your device. We do not require you to create an account, and we do not collect, store, or transmit your personal identity, custom categories, or custom autosuggestions to our servers. Your personal mental library remains entirely on your own Apple device.
We offer premium features through auto-renewing subscriptions. All payment processing is securely handled directly by Apple via your Apple ID account. We do not have access to your credit card information or billing details. To manage access to premium features, we use a third-party service (RevenueCat) which strictly uses anonymous identifiers to verify your subscription status without linking it to your personal identity.
To improve the App, we may collect anonymous, aggregated crash reports and basic usage metrics (such as which default categories are most popular) provided by Apple's native diagnostic tools. This data contains no personally identifiable information and is solely used to maintain and optimize the application's performance.
The App utilizes the following third-party services that may collect anonymous data to facilitate their specific functions:
We may occasionally update this Privacy Policy. Any changes will be posted on this page with an updated revision date. By continuing to use the App after those changes become effective, you agree to the revised policy.
