Privacy Policy

Summary

画像、音声、文書は通常ブラウザ内でローカル変換されます。動画はサーバー処理のためにアップロードされ、ダウンロード後または1時間後に削除されます。トラブルシューティングのために明示的に許可した場合のみ、より長く保持されます。omnivert.xyz では解析は初期状態で無効で、同意後に Yandex Metrica が限定的な技術データを受け取ります。Webvisor とクリックマップは無効です。寄付時には Stripe がデータを処理する場合があります。

第三者の OMNIVERT インスタンスではデータの扱いが異なる場合があります。

Conversions

Most conversions (images, documents, audio) happen entirely locally on your device using WebAssembly versions of the relevant tools (e.g. ImageMagick, Pandoc, FFmpeg). This means your files never leave your device and we will never have access to them.

Video conversions are performed on our servers because they require more processing power and cannot be done very quickly on the browser yet. Videos you convert with OMNIVERT are deleted after being downloaded, or after one hour, unless you explicitly give permission for us to store them longer purely for troubleshooting purposes.

Donations

We use Stripe on the about page to collect donations. Stripe may collect certain information about the payment and device for fraud prevention as described in their documentation on advanced fraud detection. External network requests to Stripe are deferred, and are only made after you click the button to pay.

Conversion Errors

When a video conversion fails, we may collect some anonymous data to help us diagnose the issue. This data may include:
  • The job ID, which is the anonymized file name
  • The format you converted from
  • The format you converted to
  • The FFmpeg stderr output of your job (error message)
  • The actual video file (if given explicit permission)
This information is used solely for the purpose of diagnosing conversion issues. The actual video file will only ever be collected if you give us permission to do so, where it will only be used for troubleshooting.

Analytics

設定の「プライバシーとデータ」で明示的に有効にするまで、解析は読み込まれません。omnivert.xyz で有効にすると、Yandex Metrica はページ URL、参照元、ブラウザと端末情報、おおよその位置情報を受け取り、Yandex プライバシーポリシーに従ってブラウザ保存領域や Cookie を使用する場合があります。Webvisor、クリックマップ、自動リンク追跡は無効です。ファイル名や内容は送信されず、いつでも無効にできます。

Local Storage

We use your browser's local storage to save your settings, and your browser's session storage to temporarily store the GitHub contributors list for the "About" section to reduce repeated GitHub API requests. No personal data is stored or transmitted.

The WebAssembly versions of the conversion tools we use (FFmpeg, ImageMagick, Pandoc) are also stored locally on your browser when you first visit the website, so you don't need to redownload them each visit. No personal data is stored or transmitted. You may view or delete this data at any time in the "Privacy & data" section in settings.
