Privacy Policy
Effective date: February 4, 2026 · Last updated: November 11, 2026
In short: camera images, face data and head movement never leave your iPhone or iPad. Scroll Feed has no servers and no accounts of its own.
The App sends usage statistics to Google Analytics for Firebase and shows banner ads from Google AdMob. Both are described below, with what they receive and why.
1. Introduction
Scroll Feed (“the App”) opens the mobile websites of Instagram, TikTok, YouTube and Facebook and moves their feeds when you tilt your head. The front camera follows your head, and Google ML Kit detects your face on your iPhone or iPad. This policy explains what data the App uses, what leaves your device, who receives it, and what choices you have.
| Data | Leaves your device? | Who receives it | Why |
|---|---|---|---|
| Camera frames, face detection results, head tilt | No | Nobody | Hands-free scrolling |
| Your device’s angle during setup (motion sensor) | No | Nobody | Setup |
| Usage events, device and app details, approximate location, random app instance ID, vendor identifier | Yes | Google (Firebase Analytics) | Usage statistics |
| Ad request and ad measurement data | Yes | Google (AdMob) | Showing and measuring ads |
| Your device’s advertising identifier, only if you allow tracking (version 2.0.1 and later) | Yes | Google (AdMob) | Personalizing and measuring ads |
| Whether a consent form is needed, and your choice | Request only; choice stays on your device | Google (User Messaging Platform) | Asking for consent where the law requires it |
| ML Kit performance and error metrics | Yes | Google (ML Kit) | Diagnostics |
| Your sign-ins and what you watch on those websites | Goes to those services directly, not to us | Instagram, TikTok, YouTube, Facebook | Their own services |
2. Data that stays on your device
2.1. Camera, face and head movement
The App uses the front camera while a feed or the setup is open. Google ML Kit finds your face in each camera frame and measures the up-and-down angle of your head. The App uses that angle only to decide whether to show the next or the previous video.
- Camera frames are processed on your iPhone or iPad and discarded right away. The App does not record, store or send any image or video.
- Face detection results and head movement are not stored or sent anywhere.
- The App does not show or save a camera preview.
2.2. Motion sensor
During setup, the App reads your device’s motion sensor to check that the device stands at a usable angle. This happens on your device only. The reading is not stored or sent.
3. Data that leaves your device
3.1. Usage statistics: Google Analytics for Firebase
The App sends these events to Firebase Analytics, so we can see how the App is used and where it fails:
- the screens you open (the home screen or a feed);
- the feed you choose, and how you opened it (the home grid, the Continue card, resume, or “How to use?”);
- when a feed opens and closes, how long it stayed open, why it closed, how many times you swiped by hand, and whether setup was involved;
- when setup starts, each step you finish (for the device-angle step, how long it took and how many tries), when the setup’s fallback screen appears, and how setup ends;
- whether you allowed camera access, and whether you opened Settings from the camera prompt;
- when hands-free scrolling can’t start and the technical reason, for example that the camera is unavailable;
- error codes when a page fails to load;
- for sign-in: when you tap TikTok’s login button, when a login window opens, closes or is cancelled;
- when you tap “How to use?”.
Firebase Analytics also records app opens, sessions and time in the App, together with your device model, iOS version, App version, language, and approximate location (country, region and city). Google estimates that location from your IP address; it does not use Location Services. Analytics gives each installation a random app instance ID and reads your device’s vendor identifier, which is limited to this developer’s apps.
Analytics data does not include your name, email address, passwords, or anything you see or type in a feed. It contains no camera, face, head or motion data. We do not link Analytics to AdMob or any other advertising product, and we keep Google signals off, so Analytics data is not used for advertising.
Firebase’s installation service also sends Google basic device, iOS and App details that Google says are never linked to a user or device identifier.
3.2. Ads: Google AdMob
The App shows banner ads from Google AdMob at the bottom of the screen. From version 2.0.1, ads can be personalized, depending on the choices described below. Earlier versions ask for non-personalized ads only. Ads can also depend on the App’s context and your approximate location.
According to Google, the AdMob SDK collects:
- your IP address, to estimate your general location;
- a device identifier limited to this developer’s apps;
- the ads you have seen and how you interacted with them;
- performance data, such as launch time and energy use, and crash logs.
Google uses this data to serve and measure ads, limit how often you see an ad, report results in aggregate, and prevent fraud. Where your choices allow it, Google also uses it to personalize ads. No camera, face, head or motion data is sent to AdMob or used to choose ads. Ad installs may be measured with Apple’s SKAdNetwork, which does not share your identity with ad networks.
Tracking. From version 2.0.1, the App asks for your permission to track you when you first open it. If you allow it, iOS gives AdMob your device’s advertising identifier, and Google can use it to personalize ads based on your activity in other companies’ apps and websites. If you don’t, AdMob does not receive the identifier. Earlier versions never ask, so AdMob gets no advertising identifier from them. You can change your choice at any time in iOS Settings > Privacy & Security > Tracking.
3.3. Consent: Google User Messaging Platform
Before it requests ads, the App asks Google’s User Messaging Platform whether a consent form is needed. Google decides this from your approximate location.
- European Economic Area, United Kingdom and Switzerland: Google’s consent form appears, and the App requests ads only when your choice allows it. Ads are personalized only if you consent to personalized ads. Firebase Analytics starts with its analytics storage switched off and keeps it off unless your choice allows it. While it is off, Analytics sends events without the app instance ID or the vendor identifier, and Google uses them only for aggregated, modeled statistics.
- US states with consumer privacy laws: Google may show a notice about these laws. You can opt out of the sale or sharing of your data for targeted ads with Privacy Settings on the App’s main screen.
- Everywhere else: Google does not require a form. Analytics works as described in section 3.1, and the tracking choice in section 3.2 applies to ads.
Your choice is stored on your device. Where Google’s form or notice applies, you can change your choice at any time with Privacy Settings on the App’s main screen.
3.4. Face detection diagnostics: Google ML Kit
Face detection runs entirely on your device. According to Google, ML Kit sends Google these metrics about how its features perform: device details (manufacturer, model, iOS version and build, available machine-learning hardware), the App’s bundle ID and version, a per-installation identifier that is not meant to identify you or your device, speed measurements, the image format and resolution it processed, which feature events happened, and error codes. Google uses them for diagnostics and usage analytics. ML Kit does not send camera frames or face detection results. See Google’s ML Kit data disclosure.
4. Data stored on your device
- whether you finished setup;
- the feed you used last, so the App can mark it and offer to continue;
- your consent choice, stored by Google’s consent SDK;
- cookies and sign-in sessions of the websites you open in the App (see section 5);
- the App version in which the App last asked you to rate it on the App Store.
This data stays on your device and is not sent to us. Deleting the App deletes it.
5. Websites you open in the App
The App shows the mobile websites of Instagram, TikTok, YouTube and Facebook. When you browse these feeds or sign in, you use those services directly, and their own privacy policies apply. You sign in on their pages; the App does not see, store or send your password.
The App adds small scripts to these pages. They move to the next or previous video and notice when TikTok’s login window opens. They do not collect what you see or type. Like a web browser, the App keeps the websites’ cookies and sign-in sessions on your device.
6. How we use data
- To scroll feeds with the tilt of your head, on your device.
- To understand how the App is used, and to find and fix problems.
- To show ads, which keep the App free.
We do not use your data to identify you or to build a profile of you. We do not sell your data for money. Some US state laws count personalized ads as a sale or sharing of data; section 3.3 explains how to opt out. Camera, face, head and motion data are never used for advertising, marketing or data mining, by us or by anyone else.
6.1. Legal bases (European Economic Area, United Kingdom and Switzerland)
- Camera: your permission, which you can withdraw in iOS Settings. Camera, face, head and motion data are processed only on your device and never reach us.
- Analytics: the choice you make in Google’s consent form. You can change it in Privacy Settings.
- Ads: the choice you make in Google’s consent form. You can change it in Privacy Settings.
7. Data retention
- Camera, face, head and motion data: never stored. Each camera frame is discarded as soon as it is processed.
- Analytics data: data tied to an app instance ID is deleted automatically within 14 months after you last use the App. Aggregated reports, which do not identify an installation, can be kept longer.
- Advertising and ML Kit data: kept by Google under Google’s retention policies.
- Data on your device: kept until you delete the App.
8. Children’s privacy
The App is rated 18+ on the App Store and is not intended for anyone under 18. We do not knowingly collect data from children. If you believe a child used the App, contact us and we will delete any data we can identify.
9. Security
The App has no servers of its own. The data it sends goes only to the Google services in section 3, over encrypted connections (HTTPS). The websites in section 5 handle your data under their own policies.
10. Your choices and rights
- Camera: turn camera access off in iOS Settings at any time. The App needs the camera for hands-free scrolling and does not open a feed without it.
- Ads and analytics consent: in the European Economic Area, the United Kingdom and Switzerland, change your choice in Privacy Settings on the App’s main screen.
- Tracking: from version 2.0.1, allow or deny tracking when the App asks, and change it later in iOS Settings > Privacy & Security > Tracking.
- US privacy choices: in US states with consumer privacy laws, opt out in Privacy Settings on the App’s main screen.
- Stop all collection: outside those regions the App has no in-app switch for analytics. Deleting the App stops all collection.
- Access, correction and deletion: email scrollfeed.app@gmail.com. We answer within 30 days. Analytics data is tied to a random app instance ID, not to your name, so we may not be able to find the data that belongs to you.
- Complaints: in the European Economic Area or the United Kingdom, you can also complain to your local data protection authority.
11. Changes to this policy
We may update this policy. We will post the new version on this page and change the “Last updated” date.
