Neron App Studio

1. Introduction

NERON ("we", "our", or "us") operates the Persona AI mobile application (the "App"). Persona AI lets you create an AI character from a photo and turn a script into a talking-head video. This Privacy Policy explains what information the App collects, how we use it, who receives it and how long it stays. Persona AI does not ask you to register an account or give your name or email address.

2. Information We Collect and Where It Goes

2.1 Your photo

You pick one photo for each character, from the camera or your photo library.
Persona AI does not ask you to confirm that you took the photo or have permission from the person in it, and the app does not check whose face is in it. Please only use photos you have the right to use.
The photo is kept on your device as part of the character.
Each time you generate a video, the photo is uploaded to our AI provider, fal.ai, and used there as a reference image (with the model nano-banana-2/edit) to generate your character's image.
Persona AI does not run face detection, face recognition or face tracking on the photo, and does not create or store a face template or embedding from it. To the app it is an ordinary image.
We do not use your photo to train any model of our own, and the app does not send it to any model-training job.
Where the photo is kept and for how long is described in 2.2 and section 5; how to delete it, in section 7.

2.2 Your script and your videos

The script text you write is sent to AI providers to produce speech and the talking-head video. We run these models on fal.ai: minimax/speech-02-hd (text to speech), nano-banana-2/edit (the character image, made from your photo) and veed/fabric-1.0 (the talking-head video).
The app sends the generated character image and the generated audio to the video model to make the video.
When it needs access to fal.ai (for example to start a generation), the app asks our own server (a Google Cloud function) for it. Like any server, it sees your device's IP address. It uses a scrambled (hashed) form of your IP address to limit how many requests one network can make per day.
Your finished video is not saved on your device. The app keeps a link to the video file hosted by fal.ai and plays it from that link. If you use Share, the link to the video is what gets shared.
fal.ai's own documentation states that generated files stay on its servers for at least 7 days by default and that the links are public: anyone who has the link can open the file until it expires (https://fal.ai/docs/model-apis/faq). Persona AI does not set this period. Videos are therefore kept online for a limited time and may become unavailable afterwards.
Photos you upload are stored by fal.ai under the same retention controls as generated files (https://fal.ai/docs/model-apis/data-retention).

2.3 Analytics and crash reporting

Persona AI uses Firebase Analytics and Firebase Crashlytics (Google).
Events we record: screens you open; creating and changing scenes, mood, camera angle, environment, format and resolution; choosing a template; creating an outfit or a collection (we send the length of the description or name, not its text); applying filters; switching view; looping or sharing a video; starting, finishing or failing a video generation (with your plan tier and the failure reason); starting a trial or making a purchase (package and product id, platform); and which version of a test you were shown.
We also attach these details: your plan tier, credit balance, streak, number of videos generated and number of characters, plus the app version and device information (device model, operating system version).
The events are linked to a random identifier that the app creates on your device. It is not your name or email.
Firebase may derive your approximate location (country and region) from your IP address when it receives these events.
Crash reports contain the error, where it happened, the state of the device at the time and the details above.
The app has no setting to turn analytics or crash reporting off.
Persona AI checks for app updates through Expo Updates (expo.dev). When it does, your device's IP address and the app version are sent to Expo.

2.4 Measuring our own ads (Google Ads)

Persona AI shows no ads, but we advertise Persona AI elsewhere. To measure those campaigns, the app's analytics are linked to our Google Ads account.
What is used for that measurement: app events (installs, trial starts, purchases) and the device identifiers and the Android advertising ID that go with them. The app includes the Android advertising ID permission for this.
Not exported: your name, email, photos, scripts or videos.

2.5 Notifications

The app can show a notification on your device when a video is ready. It is created on your device, after you allow notifications, and does not need our servers.
The app also includes Firebase Cloud Messaging, which may create a messaging token for your device. Our app does not send that token to our servers and does not send push messages.

2.6 Reporting a video

Coming soon. The current iOS version of the app has no in-app way to report a video, so nothing is collected for reports. This section will describe reporting when the feature is added.

2.7 Payment data

Subscriptions and purchases go through Apple (App Store) or Google (Google Play). We do not collect, process or store payment information such as card numbers or billing addresses.
We use RevenueCat to check what you have bought and unlock it. RevenueCat identifies you with an anonymous id, not an account. We receive purchase confirmation data such as subscription status.

2.8 No account

There is no account. The "Continue" screen creates the random identifier on your device, and nothing is sent to us for it.
We do not collect your name or email address in Persona AI. If you write to support, we receive the address you write from.
Persona AI does not show ads and does not use your microphone.

3. How We Use Your Information

To provide and maintain the App's functionality
To generate your character images, speech and videos with our AI provider
To manage subscription status and credit balances
To improve the App through analytics and crash reporting
To measure our own advertising campaigns (see 2.4)
To diagnose technical issues and improve stability

4. Third-Party Services

We use the following third-party services to operate the App:

fal.ai: AI image generation, speech synthesis and video generation, with the models named in 2.2. Files and requests are kept by fal.ai as described in section 5. fal.ai Privacy Policy: https://fal.ai/privacy
Firebase Analytics (Google): usage analytics and the Google Ads measurement described in 2.4. Firebase Privacy Policy
Firebase Crashlytics (Google): crash reporting. Firebase Privacy Policy
Firebase Cloud Messaging (Google): notification token (see 2.5). Firebase Privacy Policy
Google Ads: measurement of our own campaigns (see 2.4).
RevenueCat: subscription and in-app purchase management. RevenueCat Privacy Policy
Expo Updates (expo.dev): checks for app updates (see 2.3).
Apple App Store and Google Play: purchases.

5. Data Storage and Retention

On your device: your characters, their photo references, your scripts and the links to your videos are stored on your device. Deleting a character or a video in the app removes it from the app's data on your device; a cached copy of a photo you picked may stay until you clear the app's storage or remove the app.
At fal.ai: uploaded and generated files expire on fal.ai's schedule (generated files for at least 7 days by default, see 2.2), and request data (the text and file links sent with a generation) is kept for 30 days by default (https://fal.ai/docs/model-apis/data-retention).
At Google (Firebase) and RevenueCat: data is kept under those providers' own policies.
The app has no button to delete data held by fal.ai, Google Firebase or RevenueCat.

6. Data Transfers

When you use AI generation features, your photo, script and generated files are sent to fal.ai for processing. Firebase, RevenueCat and fal.ai may process data outside of the European Economic Area (EEA).

7. Your Choices

You can delete the characters and videos stored on your device in the app, or remove the app. To ask us to delete what we hold on our servers (currently nothing; video reports once the feature ships), use https://neron.app/products/persona-ai/delete-data. For anything else, including questions about your data, write to [email protected]. We do not have a self-service tool for data held by fal.ai, Google or RevenueCat. fal.ai's policy says deletion requests to fal.ai go to [email protected]. If you think your rights have been violated, you can complain to your local data protection authority.

8. Children

Persona AI is not meant for children under 13. The app has no age check. If you believe a child has sent us information, write to [email protected].

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by updating the "Last updated" date at the top of this page. We encourage you to review this Privacy Policy periodically.
