Privacy Policy
Last updated: March 21, 2026
Overview
Cura ("the App") is a photo cleanup utility for iPhone developed by ProcessFlow, Inc. ("we," "us," or "our"). We are committed to protecting your privacy. This Privacy Policy explains how the App handles your data.
The short version: We do not collect your personal data. Your photos are processed entirely on your device and never leave your phone.
Data Collection
Cura does not collect, store, or transmit your photos or personal content. There are no user accounts and no cloud uploads. However, for advertising attribution purposes, we may collect your device identifier (IDFA) and certain usage data, as described in the sections below.
Photo Access
Cura requires access to your photo library to scan for duplicates, blurry photos, and screenshots. All photo analysis is performed 100% on-device using Apple's Vision framework and Accelerate framework. No images, thumbnails, or photo metadata are ever transmitted to any external server.
Analytics
We use PostHog to collect anonymous usage analytics. This includes app opens, feature usage, and session recordings with anonymous device identifiers. No personal data is linked to these analytics. No photo content or metadata is included. You can opt out of analytics through your iOS system settings.
Error Monitoring
We use Sentry to collect anonymous crash reports and error logs. These reports help us fix bugs and improve app stability. No personal data, photo content, or identifiable information is included in crash reports.
Advertising & Attribution
To measure the effectiveness of our advertising campaigns and understand how users discover Cura, we use the following services:
- Meta (Facebook) SDK — We share your device identifier (IDFA, if you consent via the App Tracking Transparency prompt), purchase events, and app usage events (such as completing a scan or viewing the paywall) with Meta for advertising attribution and campaign measurement. Meta may use this data to link your activity to your identity for ad targeting purposes.
- TikTok Business SDK — We share the same categories of data (device identifier, purchase events, usage events) with TikTok for advertising attribution and campaign measurement. TikTok may use this data to measure ad performance and optimize campaign delivery.
- Apple Search Ads (AdServices) — We use Apple's AdServices framework to collect an attribution token that helps us understand whether you downloaded Cura from an Apple Search Ads campaign. This does not require the IDFA and no tracking permission is needed.
The data shared with Meta and TikTok is used for third-party advertising purposes and constitutes tracking as defined by Apple. You will be asked for permission via iOS's App Tracking Transparency prompt before any tracking occurs.
Third-Party Services
RevenueCat processes in-app purchases via Apple's StoreKit. RevenueCat receives only transaction data handled by Apple (purchase receipt, transaction ID). No custom user data is sent to RevenueCat by the App.
Data Storage
The App stores your free delete count in the device Keychain for tracking usage against the free tier limit. Feature vector caches (used for duplicate detection) are stored locally on your device. No data is stored on external servers.
Tracking & Your Choices
When you first open Cura, iOS will display an App Tracking Transparency (ATT) prompt asking whether you allow the App to track your activity across other companies' apps and websites. If you choose "Allow", your device identifier (IDFA) and the events described above will be shared with Meta and TikTok. If you choose "Ask App Not to Track", no data will be shared with advertising partners. You can change this setting at any time in iOS Settings → Privacy & Security → Tracking. Regardless of your choice, Apple Search Ads attribution continues to function as it does not use the IDFA.
GDPR & CCPA
If you have consented to tracking via the ATT prompt, your device identifier and certain usage data are shared with Meta and TikTok as described above. Under the GDPR and CCPA, you have the right to access, delete, or opt out of the sale or sharing of your personal data. You can revoke tracking consent at any time via iOS Settings → Privacy & Security → Tracking. For data already shared with Meta or TikTok, you may exercise your rights directly with those services. If you have further questions, please contact us at the address below.
Children's Privacy
Cura is not directed at children under the age of 13. We do not knowingly collect any personal information from children. Since the App collects no personal data from any user, it is compliant with the Children's Online Privacy Protection Act (COPPA).
Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
