It is used only to create your result and is deleted automatically as soon as the analysis finishes. For Suggestion, only the first 10 seconds are used.

What does Suggestion do?

It scores your video's hook. If the score is below 90, it writes stronger opening lines in your video's language.

Tag Finder shows the public tags, stats and description of any YouTube video. Compare tags shows which tags a competitor uses that you do not. Channel Planner shows the best days to upload.

Will my video go viral?

Nobody can promise that. Trenndly gives you suggestions that help you present your video better. Always read and edit the results before you publish.

How do I delete my data?

You can delete any History item yourself. To delete your account and related data, email us at the address in the Contact section.

Privacy Policy

1About this policy

This Privacy Policy explains how Trenndly ("Trenndly", "we", "our" or "us") handles information when you use our website at trenndly.netlify.app and our tools: video tag and title analysis, Suggestion (hook check), Competitor tools (Tag Finder, tag comparison and Channel Planner), and Video Prompt.

By creating an account or using Trenndly, you confirm that you have read this policy and the User Rules in section 13. If you do not agree, please do not use the service.

  • Preview image: a small frame taken from your video, saved only so your History looks clear.

Results we create for you

  • Tags, hashtags, keywords, titles, SEO score, hook score, stronger hook lines, scene-by-scene prompts and reference image prompts.
  • Results from Tag Finder, tag comparison and Channel Planner, which use public data from the YouTube Data API.

4Videos and AI processing

When you use Analyze, Suggestion or Video Prompt with a video, the video is sent securely to our AI provider so it can watch and listen to it and write your results. For Suggestion, only the first 10 seconds are used. Ideas you type are also processed by the AI provider to write your prompts.

We delete your video from the AI provider as soon as the analysis finishes, and we do not keep your video file ourselves. The AI provider handles information under its own terms and policies.

AI results can contain mistakes. Please read and edit every result before you publish it. Do not upload private, confidential or sensitive footage.
