Privacy Policy
Last updated: 13 November 2026
This Privacy Policy explains how NicoVid ("we", "the app") handles information when you use our Android application, a downloader for Niconico (nicovideo.jp) videos. Your trust matters, so this policy is written in plain language. By installing or using the app, you agree to the practices described below.
1. Information we collect
We do not collect, store, or transmit personal data to us. There is no account system and no sign-in. More precisely:
- No personal information is requested. NicoVid works anonymously. You are never asked for your name, email, phone number, Niconico credentials or payment details inside the app.
- Video URLs and pages. When you open or download a video, the app sends the video URL or content ID directly to Niconico's servers (www.nicovideo.jp, nvapi.nicovideo.jp and api.nicovideo.jp) to retrieve video details, the stream URL and subtitle (timed-text) tracks. Those servers see your IP address and the URL you requested as part of serving the request — the same as any request your browser would make.
- Download of media. The actual video/audio streams are downloaded directly from Niconico's CDN to your device. We do not proxy, store or log the files or the URLs.
- Nothing is sent to our servers because we do not operate any backend that receives your data.
2. What is stored on your device
- Settings and preferences (preferred quality, theme options, rewards/VIP progress) are kept in local app storage (Android SharedPreferences) on your device only.
- Watchlist and download history are stored locally on your device. They are never uploaded.
- Downloaded files are saved to your device's storage (for example your Pictures or Movies/Downloads folder) and can be deleted any time from the app or your file manager.
- Cached thumbnails use a local image cache on the device.
3. Permissions used
| Permission | Why it's needed |
|---|---|
| INTERNET | Fetch video pages, streams and subtitles from nicovideo.jp; save videos |
| ACCESS_NETWORK_STATE | Detect connectivity before/during downloads |
| POST_NOTIFICATIONS | Show progress and completion of downloads |
| FOREGROUND_SERVICE | Keep downloads running reliably in the background |
| WAKE_LOCK | Prevent the CPU from sleeping mid-download |
| READ_MEDIA_VIDEO / READ_MEDIA_IMAGES / READ_MEDIA_AUDIO | Detect and list saved videos on Android 13+ (API 33+) |
| READ_EXTERNAL_STORAGE (max SDK 32) | Access saved videos on Android 12L and below |
| WRITE_EXTERNAL_STORAGE (max SDK 28) | Save videos to shared storage on Android 9 and below |
4. Advertising & analytics
NicoVid contains no advertising SDK and no analytics or crash-reporting SDK. We do not serve or measure ads, and we do not build advertising profiles. (If a future version introduces ads or analytics, this policy will be updated before release.)
5. Third-party services
- Niconico (Nico Nico Douga, operated by Dwango/DMM) — the source of every video you view or download. Requests to nicovideo.jp are subject to Niconico's terms and privacy policy; we do not control how Niconico processes your requests.
- Open file actions — when you tap "Open" or "Share" on a downloaded file, Android's system share sheet launches another app of your choice. That interaction happens between you, Android and the chosen app, not us.
6. Children
The app is not directed at children under 13, and we do not knowingly collect data from them (we collect no data at all). Niconico content itself may carry its own age guidance — please use it accordingly.
7. Data security
- All network traffic uses HTTPS.
- No credentials, tokens or account data are collected, stored or transmitted by NicoVid.
- Local app storage is sandboxed by Android's app storage model and is accessible only to the app on a normal, non-rooted device.
8. Your choices & deleting your data
- Delete downloads at any time inside the app or with your file manager.
- Clear watchlist / history / preferences via the app's settings or Android → Apps → NicoVid → Storage → Clear data.
- Remove everything by uninstalling the app. Android deletes the app's private storage on uninstall; files you saved to shared storage remain yours to keep or delete.
9. Content rights & responsible use
Downloading does not grant you rights to the content. You may download only videos you are permitted to access and download, and you must comply with Niconico's terms of service and applicable copyright law. NicoVid is an independent tool and is not affiliated with or endorsed by Nico Nico Douga / Dwango / DMM.
10. Changes to this policy
We may update this policy as the app evolves. The "Last updated" date at the top always shows the current version. Continued use of the app after an update means you accept the revised policy.
