Privacy Policy
Last updated: September 16, 2026
This Privacy Policy sets out how usefirst.studio ("we" or "us") handles user information in connection with ShortLine, a tool we provide. ShortLine posts short videos created by the user to the user's own connected TikTok and YouTube accounts, and lets the user check the viewing data for the videos posted.
ShortLine uses YouTube API Services. By using ShortLine in connection with YouTube, the user is deemed to have agreed to the YouTube Terms of Service. For information on how Google handles data, please see the Google Privacy Policy.
Information We Collect
Within the scope permitted by the official OAuth authentication of each platform, ShortLine handles the following information.
YouTube (Google)
- Basic channel information (channel ID, channel name) — to confirm the posting destination is the correct channel
- Information about videos on the user's channel (title, publish status, scheduled publish date/time, duration) — to check posting status and prevent duplicate posts
- Viewing data for the user's channel (views, average view duration, audience retention, likes, comments, shares, subscriber change) — so the user can check the performance of posted videos
- Video files, titles, descriptions, tags, and thumbnail images uploaded by the user
Scopes used:
youtube.upload (posting videos),
youtube.readonly (reading channel and video information),
youtube.force-ssl (managing videos, such as setting thumbnails),
yt-analytics.readonly (reading viewing data)
TikTok
- Basic account information (username, profile information)
- Video files and descriptions uploaded by the user
ShortLine does not collect or store the user's password.
Purpose of Use
We use the information we collect only for the following purposes.
- To post videos to the account the user has connected, based on the user's instructions
- To confirm that the destination account/channel is the one intended
- To aggregate viewing data for posted videos so the user can use it to improve their videos
- For error diagnosis and troubleshooting to the extent necessary for the posting process
We do not use the information we collect for advertising delivery, profiling of users, or any purpose other than those above.
Third-Party Disclosure
Except where required by law, we do not sell, provide, or share the information we collect with third parties. Posting videos and retrieving viewing data are carried out through the official APIs of each platform (YouTube, TikTok). The ShortLine website and tool do not display third-party advertising or content.
ShortLine's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Data Storage and Cookies
OAuth access tokens, refresh tokens, posting records, and aggregated viewing data are stored only on the device running ShortLine and are not stored on our web servers.
The ShortLine website (fatehack.com) does not use cookies or similar technologies to store information on, or collect information from, the user's device. The post-authentication redirect page only displays the authentication code returned by each platform on screen and does not record it.
Retention Period
OAuth tokens are retained only for as long as necessary for posting and retrieving viewing data. If the user disconnects the integration, or requests deletion, we will delete the tokens we hold and the information obtained from that account within 7 days.
Disconnecting Your Account
Users may disconnect ShortLine at any time.
- Google / YouTube: You can remove ShortLine's access from Google Account security settings (third-party access)
- TikTok: You can remove ShortLine from the TikTok app under Settings and privacy → Security → App permissions
After disconnecting, the tokens we hold can no longer be used. Deleting the information we have stored does not affect videos or data on YouTube or TikTok. If you would like your data deleted, please contact us using the details below.
