YouTube API Services – Privacy Notice

Last updated: 18 October 2026

This notice describes how Unisystem Video Publisher, an internal tool of UNISYSTEM Sp. z o.o., ul. Nowy Świat 36, 80-299 Gdańsk, Poland, uses YouTube API Services. The tool is used exclusively by Unisystem’s marketing team to publish Unisystem’s own videos to our YouTube channel @UnisystemPl, to read the statistics and comments of our own videos in order to evaluate the results of promoting them, and to prepare changes to the metadata of our videos and drafts of replies to comments. It is not offered to external users.

YouTube API Services

Unisystem Video Publisher uses YouTube API Services, including the YouTube Data API and the YouTube Analytics API. By using the tool you agree to be bound by the YouTube Terms of Service. Data processed by YouTube and Google is subject to the Google Privacy Policy.

What data the tool accesses

After authorization by our channel manager (Google OAuth 2.0), the tool accesses only our own YouTube channel:

  • basic channel information (channel name and ID, list of our uploaded videos);
  • metadata of our videos: titles, descriptions, tags, language and visibility status;
  • caption (subtitle) tracks of our videos;
  • video and subtitle files that we upload to our channel;
  • comments on our videos, as returned by the YouTube Data API: the text of the comment, its date and the public display name of the commenter. Comments are written by third parties and may contain personal data;
  • aggregated statistics of our videos from the YouTube Analytics API (read-only access, OAuth scope yt-analytics.readonly): the number of views, watch time and average view duration, the number of thumbnail impressions and their click-through rate, broken down by traffic source type (including views coming from advertising), by day and by video;
  • the search phrases typed into YouTube search that led to views of our videos, with the number of views, as aggregated by the YouTube Analytics API.

Our videos and channel data are read and changed with the OAuth scopes youtube.upload and youtube.force-ssl. Where we obtain a separate authorization that is read-only, it uses the scopes youtube.readonly and yt-analytics.readonly and cannot change anything on our channel.

The tool does not access other channels, viewers’ personal data (other than the public comments described above) or revenue reports. The statistics and search phrases returned by the YouTube Analytics API are aggregated numbers and do not identify individual viewers.

How the data is used

The channel and video data is used only to upload our own videos to our channel as private, to set and update their titles, descriptions, chapters, tags, language and subtitles, and to verify the result. The tool never changes the visibility of a video; videos are published manually by an employee in YouTube Studio.

The statistics and search phrases from the YouTube Analytics API are used only by our marketing team, for two purposes: to assess the results of promoting our own videos (how many views of our videos come from advertising, per day and per video, compared with the cost of the promotion), and to prepare proposed changes to the titles, descriptions, chapters, tags, subtitles and thumbnails of our own videos, based on how viewers find and watch them. This access is read-only. We do not use the statistics for any other purpose, and we do not use them to profile or identify viewers.

The comments on our videos are used only to review what viewers ask and write about our videos, to sort the comments (for example, a question about a product or spam) and to prepare drafts of replies. The tool never replies to a comment, hides it, reports it, deletes it or blocks a user: a reply is written and published only by an employee in YouTube Studio. The names of the commenters are left out of the reports and drafts prepared from the comments. We do not use comments to profile viewers or to build advertising audiences.

Nothing is published automatically. Proposed changes to the metadata, subtitles and thumbnails of our videos are reviewed and approved by an employee before they are applied to the channel.

Storage, sharing and deletion

We do not sell the data obtained through YouTube API Services and we do not disclose it to anyone outside Unisystem, except as described in this section. The tool does not use cookies and does not collect information from users’ devices.

The data read from the YouTube Data API and the YouTube Analytics API for the review described above (channel and video metadata, caption tracks, comments, statistics and search phrases) is saved in files on a company computer used by our marketing team, in a dedicated folder that is not shared. We keep each file for no longer than 30 days from the day it was read. Older files are deleted every time the review is run, and anyone on the team can delete them earlier. After 30 days the data is deleted or read again from YouTube. At least every 30 days we also check that our authorization to use the data is still valid; if it is not, we delete the files and stop reading.

The files are analysed with an AI assistant used by our marketing team, a service provider that processes them on our behalf only to prepare the reports, proposed changes and reply drafts described above. We do not allow the data to be used to train AI models, and we do not disclose it to anyone else.

The aggregated viewing statistics used to evaluate the results of promoting our videos (view counts by day, traffic source type and video) are also saved in a local snapshot of our marketing data on a company computer used by our marketing team, together with other marketing figures. A copy of that snapshot is uploaded daily to a private storage bucket (Cloudflare R2) read by our internal marketing dashboard; the bucket has no public access, and the dashboard is available only to authorized Unisystem staff after logging in (Cloudflare Access). The statistics are not sold, shared or disclosed to third parties. We keep them only as long as they are needed to evaluate the results of promoting our videos. The tool checks that its access is still authorized every time it collects the statistics. When access is revoked, the tool stops collecting the statistics, and we delete the stored YouTube Analytics statistics, including the copy in the private storage bucket, within 30 days of the revocation. The files with comments, metadata, search phrases and other statistics described above are not copied to the dashboard bucket.

If you wrote a comment on one of our videos and want us to delete any copy of it that we hold, write to contact@unisystem.com; you can also delete or edit the comment itself on YouTube.

The OAuth access credential (refresh token) is stored only on a company computer used by our marketing team and is not shared with third parties. It is deleted when access is revoked or when the tool is no longer used.

Revoking access

Access granted to the tool, including access to YouTube Analytics, can be revoked at any time on the Google security settings page: https://security.google.com/settings/security/permissions. After access is revoked, the tool stops reading data from YouTube and we delete the data described in this notice within 30 days.
