Effective Date

Effective Date: August 11, 2026

Overview

Swipe the Flow does not require account creation or user login.

The developer does not operate account systems, cloud storage, or user databases for the app. Swipe the Flow uses Google Mobile Ads SDK to display ads and Google Analytics for Firebase to understand whether important app features and the optional Pro purchase flow are working as intended.

Product Analytics

Swipe the Flow uses Google Analytics for Firebase to measure a limited set of product events, such as attempts to add another image layer, views of the Pro offer, purchase starts, and verified purchase completions.

Google Analytics may process an app-instance identifier, product interaction events, purchase completion events, and approximate location derived from a masked IP address. The app does not send your photos, videos, text input, email address, name, or account information to Analytics.

Analytics data is used only to measure app usage and improve product features. It is not linked to your identity and is not used to track you across apps or websites. Automatic screen reporting, IDFV collection, advertising-personalization signals, and Analytics access to IDFA are disabled.

Advertising

Swipe the Flow uses Google Mobile Ads SDK to display advertisements.

The app requests only non-personalized ads. It does not use the advertising identifier for tracking and does not use App Tracking Transparency. The app does not track users across apps or websites owned by other companies.

For users in the European Economic Area, the United Kingdom, and Switzerland, ad consent is managed through Google's User Messaging Platform where required.

To serve non-personalized ads, Google may process limited information such as IP address, app interactions, ad impressions, and ad clicks for ad delivery, fraud prevention, and ad performance measurement. This information is not linked to your identity.

For more information about how Google handles data, please review the Google Privacy Policy.

Photos Permission

Swipe the Flow may request access to your Photos library only when you choose to save a screenshot or recorded video. This access is used solely to save content you create in the app to your device's Photos library. Photos and videos are processed on your device and are not uploaded by the app.

Developer Data Handling

Swipe the Flow does not create user accounts and does not use developer-operated backend services to store user profiles, uploaded content, or account data.

In-App Purchases

Swipe the Flow offers an optional one-time in-app purchase, "Swipe the Flow Pro," which removes ads and unlocks additional visual options. Purchases are processed by Apple through the App Store. The developer does not collect or store your payment information. A verified purchase completion may be reported to product analytics without payment details or account information.

Third-Party Services

Swipe the Flow uses Google Mobile Ads SDK as a third-party advertising service and Google Analytics for Firebase as a product analytics service.

Children's Privacy

Swipe the Flow is not directed to children under 13. The developer does not knowingly collect personal information from children through developer-operated features. Third-party advertising and analytics services may process limited data as described above.

Changes to This Privacy Policy

This Privacy Policy may be updated from time to time to reflect app changes, advertising changes, or legal requirements. The latest version will be posted on this page.
