YouTube API Services — notice

Krupno uses YouTube API Services. When you connect a YouTube channel, the App accesses YouTube on your behalf through the official YouTube API Services. By using these features you agree to the YouTube Terms of Service, and Google's handling of your data is described in the Google Privacy Policy.

1. What data we collect

2. What we do NOT do

3. How data is processed

Data is stored on servers operated by the Operator within the European Union. Media files you upload are processed by our own processing servers: preparing the video format for each platform, speech recognition for automatic subtitles (run on our own servers, not by a third party) and rendering.

AI caption drafting (Anthropic). To draft captions, titles, descriptions and hashtags, the App sends to Anthropic PBC (Claude API) a few still frames of the selected video (or the photo), the text of the speech recognised in it, any hint you typed and your brand profile. The same service is used when you ask for ideas, scripts, subtitle translation or highlights. Anthropic acts as our processor for this purpose only; under its commercial terms, content sent through its API is not used to train its models. No account data, access tokens or statistics are sent. Every AI draft is shown to you and can be edited before anything is published.

3a. Data on your device, cookies and similar technologies

The App stores the following on your device, in the App's own protected storage: your sign-in session (access and refresh tokens, kept in the system keychain), your preferences, drafts of posts and edits, and local copies of the media you are editing or have chosen to upload. This information is used only to run the App and is removed when you sign out, delete the draft or uninstall the App. The App does not use advertising identifiers and does not track you across other apps or websites.

When you connect a social account, the sign-in happens on a web page of the respective platform (Google, Meta or TikTok). That platform may place, access or recognize cookies or similar technologies on your device according to its own policies (for Google, see the Google cookies policy). Our own website at krupno.app and the App's server do not set cookies of their own.

4. Platform data

Use of data received from YouTube API Services is subject to the Google Privacy Policy and the YouTube Terms of Service. Use of data received from Meta and TikTok APIs is limited to the features described above. You can revoke the App's access at any time in the security settings of the respective platform (e.g. Google security settings: https://security.google.com/settings/security/permissions).

5. Retention and deletion

Your data is kept while your account is active. You may request deletion of your account and all associated data at any time via the App or by writing to biuro@wixmart.pl; deletion is completed within 30 days. Disconnecting a social account removes its stored token immediately.

Data obtained from YouTube API Services is handled to the stricter schedule required by the YouTube API Services Terms of Service:

6. Your rights (GDPR)

You have the right of access, rectification, erasure, restriction, portability and objection. Requests: biuro@wixmart.pl. You may lodge a complaint with the Polish supervisory authority (UODO).
