Privacy Policy
Last updated: 6 November 2026 · Applies to the Duovid apps for iOS and Android
- Duovid has no accounts, no servers of its own, no ads, no analytics and no tracking.
- Your videos, photos, voice, scripts and captions are processed and stored only on your device.
- Nothing is uploaded. A video only leaves your phone when you save or share it.
- The only network use is an optional download of a speech model for auto captions, and an optional GIPHY search when you add a GIF or sticker from GIPHY.
1. Who we are
Duovid (“the app”) is made by Gremza (“we”, “us”). It is a video app for reaction videos, selfie videos and simple edits. This policy explains what the app does with your information. Because Duovid works entirely on your device, the answer is: almost nothing leaves it.
2. Data we collect
We do not collect any personal data. Duovid does not ask for your name, email, phone number or any login. We do not run a backend that receives your content, and the app contains no advertising, analytics, crash-reporting or tracking SDKs.
We do not sell, rent or share data with anyone, because we do not have it.
3. Permissions and what they are used for
Duovid asks for the following permissions only when a feature needs them. You can deny or revoke any of them in your device settings; the related feature will then be unavailable.
| Permission | Why Duovid needs it |
|---|---|
| Camera | To record your selfie or your reaction next to the video you are commenting on. |
| Microphone | To record your voice, voice-overs and commentary. |
| Photos / media | To let you pick videos and photos to react to or edit, and to save finished videos to your gallery. Duovid only reads the items you choose. |
| Speech recognition (iOS) | To generate automatic captions from your voice. Duovid requires Apple's recognizer to run on-device, so your audio is not sent to Apple. |
| Notifications (Android) | To show progress while a video is exported or a speech model is downloaded in the background. |
| Internet (Android) | Only to download an optional speech model and, when you open the GIPHY picker, to search and download GIFs and stickers from GIPHY (see section 5). |
4. How your content is processed and stored
- Recordings and projects (videos, photos, audio, text, captions and drafts) are stored in the app's private storage on your device.
- Teleprompter scripts and settings are stored locally on your device.
- Auto captions are created on your device, either with the speech recognizer built into your phone or with a downloaded speech model. Your voice is never uploaded.
- Green screen (cutting you out of the background) is computed on your device.
- Videos shared into Duovid from other apps (via the share sheet) are copied into the app's local storage on your device.
- Exported videos are saved to your gallery or passed to the app you choose in the share sheet. What happens to them after that is governed by that app or service.
Your device's own backup (iCloud on iPhone, Google backup on Android) may include Duovid's local data, depending on your device settings; these backups are handled by Apple or Google, not by us. On Android only settings and teleprompter scripts are backed up. Downloaded speech models are never backed up.
5. Network connections
Duovid works offline. It connects to the internet in two optional situations only:
- Speech model download. When you tap Download for a caption language that your phone cannot transcribe by itself (for example Albanian), the app downloads a speech model file from Hugging Face. Like any download, this request reveals your IP address and basic device/network information to that host, as described in Hugging Face's privacy policy. No audio, video, text or personal information is sent. You can delete downloaded models at any time in Settings.
- GIPHY search (GIFs and stickers). When you open the GIPHY picker to add a GIF or sticker on top of your video, the app sends your search terms (or a request for trending GIFs) to GIPHY and downloads the previews and the GIF you pick. Like any web request, this reveals your IP address and basic device/network information to GIPHY, as described in GIPHY's privacy policy. Nothing else is sent: no account, no identifiers, and none of your videos, photos, audio or projects. Duovid never contacts GIPHY unless you open the picker, and the GIF you add is stored only on your device.
On Android, the green-screen feature uses Google's on-device ML Kit library. According to the ML Kit terms, ML Kit may contact Google to receive model updates and may send anonymous performance and usage metrics about the library itself to Google. It does not send your camera images or videos.
Links to the App Store or Google Play (for example “Rate Duovid”) open in those stores, which apply their own privacy policies.
6. Data retention and deletion
Your data stays on your device for as long as you keep it. You are in full control:
- Delete an individual project from the home screen.
- Delete all projects and remove downloaded speech models in Settings.
- Uninstalling Duovid removes all of its data from your device. Videos you saved to your gallery are not affected.
Because we do not hold any of your data, there is nothing for us to access, correct, export or delete on our side.
7. Children
Duovid does not knowingly collect personal information from anyone, including children under 13 (or the equivalent minimum age in your country), because it does not collect personal information at all.
8. Your rights
Depending on where you live (for example under the GDPR in the EU/EEA or the UK, or the CCPA in California), you have rights to access, correct, delete and port your personal data and to object to its processing. Since Duovid does not collect or store personal data on any server, these rights are exercised directly on your device as described in section 6. If you have any question, contact us at the address below.
9. Changes to this policy
If the way Duovid handles data changes, we will update this page and the “Last updated” date above. Significant changes will also be mentioned in the app's release notes.
