Privacy Policy

Effective date: May 29, 2026

This Privacy Policy explains how Revio ("Revio", "the App", "we", "us", or "our") collects, uses, discloses, and protects information when you use the App.

If you do not agree with this Privacy Policy, please do not use the App.

1. Contact

For privacy questions, support, deletion requests, or other inquiries, contact us at: ad.k9studio@gmail.com.

2. Summary

Revio is a photo editing and AI enhancement app. The App may access photos you choose from your library, photos you take with the camera, and edited images you save.

Some features run on your device. Some AI features may require cloud processing, where an optimized copy of the selected image is uploaded to Firebase Cloud Functions and/or fal.ai so the requested result can be generated.

We do not sell your photos. We do not use your photos to train our own AI models. Third-party AI providers may process uploaded images according to their own terms and privacy policies.

3. Information We Collect

Photos and image data

When you choose, capture, edit, enhance, upload, or save a photo, the App processes the image data needed for the selected feature.

Photo thumbnails, albums, and selected full-resolution images are accessed only after you grant permission where iOS requires it. The App displays and processes photos so you can choose and edit them.

When a cloud AI feature is used, the App may upload an optimized copy of the selected image and related processing settings, such as model type, enhancement mode, or image URL, to cloud services.

App activity and diagnostics

We may collect app activity and diagnostic data, including:

app launches;
screen views;
feature usage events;
selected processing mode;
processing status and errors;
crash logs;
non-fatal error reports;
app version, build number, bundle identifier, installation ID, and session ID;
timestamps and service status information.

This data helps us understand feature usage, find bugs, prevent abuse, improve performance, and keep the App stable.

Purchases

If you purchase or restore Revio Pro, Apple processes the transaction. We may receive purchase status, product identifier, entitlement status, and related App Store transaction information needed to unlock or restore Pro features.

We do not receive your full payment card number or full Apple ID credentials.

Advertising and tracking-related information

The free version of the App may display ads or use ad-supported flows. If advertising SDKs or ad measurement are enabled, the App may process identifiers, ad interaction data, device information, and usage events for ad delivery, frequency control, fraud prevention, and measurement.

On iOS, advertising and measurement may use Google Mobile Ads, Apple's App Tracking Transparency framework, the Identifier for Advertisers when authorized, and related privacy controls available in iOS settings.

Contact information

If you contact us by email, we collect your email address, message content, and any information you choose to include so we can respond and provide support.

4. Permissions Used by the App

The App may request these iOS permissions:

Camera: to take a new photo for editing or enhancement;
Photo library: to let you choose photos and display recent images where iOS requires permission;
Notifications: to send optional app updates, offers, or feature notifications if you opt in;
Network access: to process cloud AI tasks, download AI models, use Firebase services, restore purchases, load store information, show ads, and operate the App.

You can change permissions in iOS Settings. If you disable a permission, related features may not work.

5. How We Use Information

We use information to:

provide photo editing, AI enhancement, background removal, colorization, restore, retouch, and save features;
process selected photos locally or through cloud services when needed;
display before and after results;
maintain Pro purchase status and restore purchases;
provide ads or ad-supported flows where applicable;
analyze usage and improve the App;
diagnose crashes, bugs, network issues, and service failures;
protect the App against abuse, fraud, and unauthorized access;
respond to support and privacy requests;
comply with legal obligations and enforce our Terms of Use.

6. Cloud AI Processing

Some AI features may upload an optimized copy of your selected image to cloud services. The App uses Firebase Cloud Functions to proxy AI requests and may use fal.ai models for features such as enhancement, face restoration, portrait retouching, and background removal.

Cloud processing may involve:

uploading the selected image or optimized image file;
creating a temporary image URL;
sending the URL and processing settings to an AI model;
checking processing status;
downloading or displaying the processed result.

Cloud processing is used only to provide the feature you requested, troubleshoot processing errors, keep the service secure, and operate the App.

7. Third-Party Services

The App may use third-party services, including:

Apple App Store and StoreKit for purchases, refunds, purchase validation, and restoration;
Google Mobile Ads and Google services for ads, ad measurement, analytics, crash reporting, and app services;
Google ML Kit and on-device models for selected image analysis and editing features;
Firebase Analytics for usage analytics;
Firebase Crashlytics for crash and error reporting;
Firebase Realtime Database for operational analytics and session status;
Firebase App Check and Apple app attestation services for abuse prevention and app verification;
Firebase Cloud Functions for backend processing;
fal.ai for AI image processing;
OneSignal for optional push notifications and notification preferences;
advertising services if ads are enabled.

These third parties may process information according to their own terms and privacy policies. Useful references include:

8. How We Share Information

We may share information:

with service providers that help operate the App, including cloud AI, analytics, crash reporting, app verification, purchases, storage, and advertising;
with Apple for App Store purchases, refunds, restoration, and platform services;
with Google for Firebase, Google Mobile Ads, analytics, crash reporting, and related app services;
with OneSignal for optional push notifications and notification preferences;
when required by law, legal process, or government request;
to protect rights, safety, security, and prevent fraud or abuse;
as part of a merger, acquisition, financing, or transfer of business assets, subject to appropriate privacy protections.

We do not sell your photos.

9. Retention

Photos processed only on your device remain on your device unless you choose to upload or save them.

Photos uploaded for cloud AI processing may be stored temporarily by Firebase, fal.ai, or related infrastructure as needed to provide results, debug failures, secure the service, or comply with service provider operations. Generated files from AI providers may remain available for a limited time and may later be deleted.

Analytics, crash logs, session data, purchase entitlement data, and support emails may be retained as long as reasonably needed for the purposes described in this Policy, unless a longer period is required or permitted by law.

10. Security

We use reasonable technical and organizational measures to protect information, including platform security controls, Firebase App Check, HTTPS network connections, and limiting cloud AI requests through backend functions.

No method of transmission or storage is completely secure. We cannot guarantee absolute security.

11. Your Choices and Rights

Depending on your location, you may have rights to access, correct, delete, restrict, object to, or receive a copy of certain personal information.

You can:

manage Camera, Photos, Notifications, and related permissions in iOS Settings;
delete local photos or edited results from your device or photo library;
request deletion of your Revio account in the App from Profile or Settings;
request account and associated data deletion through our Delete Account page;
manage or cancel App Store subscriptions from your Apple ID subscription settings;
contact us at ad.k9studio@gmail.com for privacy requests related to information we control.

We may need to verify your request before responding.

12. International Processing

The App and its service providers may process information in countries or regions other than where you live. These countries may have different data protection laws. When required, we rely on appropriate legal mechanisms to protect transferred information.

13. Children's Privacy

The App is not intended for children under 13 years old, or under the minimum age required by local law. We do not knowingly collect personal information from children. If you believe a child provided personal information, contact us and we will take appropriate steps.

We may update this Privacy Policy from time to time. If we make material changes, we will take reasonable steps to notify you, such as updating the effective date, posting the new policy, or showing notice in the App.

Your continued use of the App after an updated Privacy Policy becomes effective means you acknowledge the updated Policy.

15. Terms of Use
